Experiences and factors influencing a sample of teachers in New York state public elementary and middle schools to focus on environmental education in their teaching.
This study focuses on how fourteen elementary and middle level teachers in New York chose to teach environmental topics as part of their science curricula. Prior research suggested that factors influencing teachers to make curricular decisions are different from those that motivated them to become teachers in the first place Espinet, et.
Studies examining experiences that influence people to practice "environmentally responsible" behaviors Chawla, ; McGarry, ; Tanner, suggested that positive childhood contacts with nature were important predictors for such behavior in adulthood. Findings of this study were largely consistent with these results, however, this sample of teachers viewed their childhood nature experiences as being mostly responsible for the development of their appreciation of the environment, while their actual decision to begin teaching EE was primarily influenced by other experiences, as discussed above.
This study also examined how these teachers prepared themselves for teaching EE. The findings indicate that these teachers used a wide variety of preparation strategies. A minority reported becoming prepared for teaching EE through their pre-service teacher education programs. These results were in agreement with prior findings that most teacher education programs in this country do not include a focus on EE.
Even where preparation for EE is included, it has been rated by the participants as. I will highlight the following teaching strategies in my presentation: 1 the decision of include climate-related works at the end of syllabi for courses in subjects like "The Literature of Energy" in order to complicate and contextualize readings from earlier in the courses and to delay the climate topic until I feel students are ready to face it; 2 breaking down climate into an array of specific, graspable sub-issues food, water, transportation, architecture in courses on sustainability literature; and 3 appreciating the psychology of "numbers and nerves" in course design for topics such as genocide and climate change that seem to require quantitative description for instance, psychic numbing, pseudoinefficacy, the prominence effect, the asymmetry of trust, and the trans-scalar imaginary.
This presentation will briefly describe my own experiences teaching climate change literature at the University of Nevada, Reno, and the University of Idaho and will also draw from my forthcoming book, with psychologist Paul Slovic, titled Numbers and Nerves: Information, Emotion, and Meaning in a World of Data Oregon State University Press, October Towards Rare Itemset Mining.
While mining literature has been almost exclusively focused on frequent itemsets, in many practical situations rare ones are of higher interest e.

Environmental laws for mining activities in Provincia de San Juan Argentina , gravel mines exploitation.
This paper analyses San Juan Province - Argentina prevailing environmental legislation for mining activity and gravel mines. The study focuses the subject from a mining engineering point of view. These three courses served as case studies for class-based, quasiquantitative pilot investigation aimed at gaining a deeper insight into some of the issues involved in the implementation in college of nontraditional, open-ended, problem-solving-oriented teaching strategies which are in dissonance with the cognitive or affective styles and functional paradigms of most students.
This probe into the dissonance issue revealed that prospective teachers are capable of handling the new instructional model and do gain in their higher-level cognitive learning. However, undergraduates perceive these courses to be either difficult or not in accord with their needs, and their appreciation of the instructional techniques and style employed is different from that of graduate students accordingly. Towards a comprehensive knowledge package for teaching proof: A focus on the misconception that empirical arguments are proofs.
Full Text Available The concept of proof is central to meaningful learning of mathematics, but is hard for students to learn. A serious misconception dominant amongst students at all levels of schooling is that empirical arguments are proofs. An important question, then, is the following: What knowledge might enable teachers to help students overcome this misconception? Major elements of this knowledge package are summarised and its further development is contributed to by discussing a research-based instructional intervention found to be effective in helping secondary students begin to overcome the misconception that empirical arguments are proofs.
Implications for mathematics teacher education are considered. Trust Mines. The United States and the Navajo Nation entered into settlement agreements that provide funds to conduct investigations and any needed cleanup at 16 of the 46 priority mines , including six mines in the Northern Abandoned Uranium Mine Region. We designed a qualitative study using a focus group to allow participants to elaborate freely and facilitate a discussion.
Participants were surgeons with extensive experience in performing the Onstep technique from If trainees are inexperienced, the training setup should be a traditional step-by-step programme. A training setup should consist of an explanation of the technique with emphasis on anatomy and difficult parts of the procedure The nature of science NOS has become a central goal of science education in many countries.
This study refers to a developmental work research program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students. The 1-year-long, , program consisted of a series of activities to support teachers to develop their pedagogical content knowledge of NOS.
In order to accomplish our goal, we enabled teacher-researchers to analyze their own discourse practices and to trace evidence of effective NOS teaching. Many studies indicate the importance of examining teachers' discussions about science in the classroom, since it is teachers' understanding of NOS reflected in these discussions that will have a vital impact on students' learning.
Our proposal is based on the assumption that reflecting on the ways people form meanings enables us to examine and seek alternative ways to communicate aspects of NOS during science lessons. The analysis of discourse data, which has been carried out with the teacher-researchers' active participation, indicated that initially only a few aspects of NOS were implicitly incorporated in teacher-researchers' instruction.
As the program evolved, all teacher-researchers presented more informed views on targeted NOS aspects. On the whole, our discourse- focused professional development program with its participatory, explicit, and reflective character indicated the importance of involving teacher-researchers in analyzing their own talk. It is this involvement that results in obtaining a valuable awareness of aspects concerning pedagogical content knowledge of NOS teaching.

In P schools, the moral education debate often focuses on character education programs or other moral curricula. Such programs and curricula are championed as a means of teaching morality and transmitting moral…. Technologies for Decreasing Mining Losses.
In case of stratified deposits like oil shale deposit in Estonia, mining losses depend on mining technologies. Current research focuses on extraction and separation possibilities of mineral resources. Selective mining , selective crushing and separation tests have been performed, showing possibilities of decreasing mining losses.
Rock crushing and screening process simulations were used for optimizing rock fractions. In addition mine backfilling, fine separation, and optimized drilling and blasting have been analyzed. All tested methods show potential and depend on mineral usage.
Usage in addition depends on the utilization technology. The questions like stability of the material flow and influences of the quality fluctuations to the final yield are raised. It remains a dilemma for social work educators to teach research so that it can be embraced by students as an integral part of social work practice.

Drawing on developments in data mining and techniques in secondary data…. Bauxite Mining Sustainably. In , the International Aluminum Institute began a program to report on the bauxite mining and rehabilitation activities of the worldwide industry. A survey process was initiated and reports were published in , and Mine drivage in hydraulic mines.
Range of mine drivage is high due to the large number of shortwalls mined by hydraulic monitors. Reducing mining cost in hydraulic mines depends on lowering drivage cost by use of new drivage systems or by increasing efficiency of drivage systems used at present. The following drivage methods used in hydraulic mines are compared: heading machines with hydraulic haulage of cut rocks and coal, hydraulic monitors with hydraulic haulage, drilling and blasting with hydraulic haulage of blasted rocks.
Mining and geologic conditions which influence selection of the optimum mine drivage system are analyzed. Standardized cross sections of mine roadways driven by the 3 methods are shown in schemes. Support systems used in mine roadways are compared: timber supports, roof bolts, roof bolts with steel elements, and roadways driven in rocks without a support system.
Data on mine drivage in hydraulic coal mines in the Kuzbass are discussed. Decision mining enriches process models with rules underlying decisions in processes using historical process execution data. Choices between multiple activities are specified through rules defined over process data. Existing decision mining methods focus on discovering mutually-exclusive rules,. Mannhardt, F. Decision mining revisited - Discovering overlapping rules. Internet technologies in the mining industry. Towards unattended mining systems.
Global suppliers of longwall systems focus mainly on maximising the efficiency of the equipment they manufacture. Given the fact that, since , coal demand on world markets has been constantly on the increase, even during an economic downturn, this endeavour seems fully justified. However, it should be remembered that maximum efficiency must be accompanied by maximum safety of all underground operations.
This statement is based on the belief that the mining industry, which exploits increasingly deep and dangerous coal beds, faces the necessity to implement comprehensive IT systems for managing all mining processes and, in the near future, to use unmanned mining systems, fully controllable from the mine surface. The computerisation of mines is an indispensable element of the development of the world mining industry, a belief which has been put into practice with e- mine , developed by the FAMUR Group.
Data mining , mining data : energy consumption modelling. Most modern mining operations are accumulating large amounts of data on production and business processes. Data, however, provides value only if it can be translated into information that appropriate users can utilize. This paper emphasized that a new technological focus should emerge, notably how to concentrate data into information; analyze information sufficiently to become knowledge; and, act on that knowledge.
The data-to-action approach was exercised in the development of an energy consumption model ECM , in partnership with a major US-based copper mining company, 2 software companies, and the MISOM laboratory. The approach begins by integrating several key data sources using data warehousing techniques, and increasing the existing level of integration and data cleaning. An online analytical processing OLAP cube was also created to investigate the data and identify a subset of several million records.
Data mining algorithms were applied using the information that was isolated by the OLAP cube. The data mining results showed that traditional cost drivers of energy consumption are poor predictors. A comparison was made between traditional methods of predicting energy consumption and the prediction formed using data mining. Traditionally, in the mines for which data were available, monthly averages of tons and distance are used to predict diesel fuel consumption.
However, this article showed that new information technology can be used to incorporate many more variables into the budgeting process, resulting in more accurate predictions. The ECM helped mine planners improve the prediction of energy use through more data integration, measure development, and workflow analysis. Effect of teaching motivational interviewing via communication coaching on clinician and patient satisfaction in primary care and pediatric obesity- focused offices.
Studies indicate needed improvement in clinician communication and patient satisfaction. Motivational interviewing MI helps promote patient behavior change and improves satisfaction. In this pilot study, we tested a coaching intervention to teach MI to all clinic staff to improve clinician and patient satisfaction.
In the intervention clinics one primary care and one pediatric obesity- focused , we trained all clinic staff in MI through meetings as a group seven times, directly observing clinicians in practice times, and providing real-time feedback on MI techniques. In all clinics, we assessed patient satisfaction via anonymous surveys and also assessed clinician burnout and self-rated MI skills.
Clinicians in the intervention clinics reported improvements in burnout scores, self-rated MI skills, and perceived cohesion whereas clinicians in the control clinic reported worse scores. Patient satisfaction improved in the intervention clinics more than in the control clinics. This is the first study to find some benefit of training an entire clinic staff in MI via a coaching model. It might help to train staff in MI to improve clinician satisfaction, team cohesion, perceived skills, and patient satisfaction.

Vesterbacka, P. In Finland, mining became popular in the mid's when the mining amendments to the law made the mining activities easier for foreign companies.
Also the price of the minerals rose and mining in Finland became economically profitable. Expanding mining industry brought new challenges to radiation safety aspect since radioactive substances occur in nearly all minerals. In Finnish soil and bedrock the average crystal abundance of uranium and thorium are 2. It cannot be predicted beforehand how radionuclides behave in the mining processes which why they need to be taken into account in mining activities.
The guide sets the limits for radiation doses to the public also from mining activities. In general, no measures to limit the radiation exposure are needed, if the dose from the operation liable to cause exposure to natural radiation is no greater than 0. If the exposure of the public may be higher than 0. In that case the mining company responsible company has to make a radiological baseline study. The baseline study must focus on the environment that the mining activities may impact.
The study describes the occurrence of natural radioactivity in the environment before any mining activities are started. The baseline study lasts usually for two to three years in natural circumstances. Based on the baseline study measurements, detailed information of the existing levels of radioactivity in the environment can be attained. Once the mining activities begin, it is important that the limits are set for the wastewater discharges to the environment and environmental surveillance in the vicinity of.

Acid mine drainage AMD is recognized as one of the most serious environmental problem associated with mining industry. Acid water, also known as acid mine drainage forms when iron sulfide minerals found in the rock of coal seams are exposed to oxidizing conditions in coal mining. Until , mine drainage in Hongai coal mines was not treated, leading to harmful effects on humans, animals and aquatic ecosystem. This report has examined acid mine drainage problem and techniques for acid mine Extending mine life.
Mine layouts, new machines and techniques, research into problem areas of ground control and so on, are highlighted in this report on extending mine life. The main resources taken into account are coal mining , uranium mining , molybdenum and gold mining. Full text: The economic and environmental sustainability of uranium mining has been analysed by Monash University researcher Dr Gavin Mudd in a paper that challenges the perception that uranium mining is an 'infinite quality source' that provides solutions to the world's demand for energy.
Dr Mudd says information on the uranium industry touted by politicians and mining companies is not necessarily inaccurate, but it does not tell the whole story, being often just an average snapshot of the costs of uranium mining today without reflecting the escalating costs associated with the process in years to come.
The deeper the mining process required to extract the ore, the higher the cost for mining companies, the greater the impact on the environment and the more resources needed to obtain the product. I t is clear that there is a strong sensitivity of energy and water consumption and greenhouse emissions to ore grade, and that ore grades are likely to continue to decline gradually in the medium to long term.
These issues are critical to the current debate over nuclear power and greenhouse emissions, especially with respect to ascribing sustainability to such activities as uranium mining and milling. For example, mining at Roxby Downs is responsible for the emission of over one million tonnes of greenhouse gases per year and this could increase to four million tonnes if the mine is expanded. Focus on focusing.
The discovery and impact of the principle of strong focusing was celebrated at a history Symposium at Stanford on 25 July in the course of the US Summer School on Particle Accelerators.

The third section contains subsections on passive treatment, biological treatment, physiochemical treatment, and a new subsection on beneficial uses for mine drainage and treatment wastes. Factors influencing mine rescue team behaviors.
Participants in the study included mine rescue team members, team trainers, mine officials, state mining personnel, and individual mine managers. A subset of the data consists of responses from participants with mine rescue backgrounds. These responses were noticeably different from those given by on-site emergency personnel who were at the mine and involved with decisions made during the first moments of an event.
As a result, mine rescue team behavior data were separated in the analysis and are reported in this article. By considering the responses from mine rescue team members and trainers, it was possible to sort the data and identify seven key areas of importance to them. On the basis of the responses from the focus group participants with a mine rescue background, the authors concluded that accurate and complete information and a unity of purpose among all command center personnel are two of the key conditions needed for an effective mine rescue operation.

Implications of Emerging Data Mining. Data Mining describes a technology that discovers non-trivial hidden patterns in a large collection of data.
Although this technology has a tremendous impact on our lives, the invaluable contributions of this invisible technology often go unnoticed. This paper discusses advances in data mining while focusing on the emerging data mining capability. Such data mining applications perform multidimensional mining on a wide variety of heterogeneous data sources, providing solutions to many unresolved problems.
This paper also highlights the advantages and disadvantages arising from the ever-expanding scope of data mining. Data Mining augments human intelligence by equipping us with a wealth of knowledge and by empowering us to perform our daily tasks better. As the mining scope and capacity increases, users and organizations become more willing to compromise privacy.
Data integration and analysis capability of combining business and financial trends together with the ability to deterministically track market changes will drastically affect our lives.

The Exclusive Economic Zone EEZ declared by President Reagan in March has met with a mixed response from those who would benefit from a guaranteed, nautical-mile km protected underwater mining zone off the coasts of the United States and its possessions.
On the one hand, the U. Department of the Interior is looking ahead and has been very successful in safeguarding important natural resources that will be needed in the coming decades. On the other hand, the mining industry is faced with a depressed metals and mining market. Less qualified teachers may have difficulty teaching ESS because of a lack of conceptual understanding, which leads to diminished confidence in content knowledge.
More importantly, teachers' limited conceptual understanding of the core ideas automatically leads to a lack of pedagogical content knowledge. This mixed methods study aims to explore the ways in which current secondary schooling, especially the small numbers of highly qualified ESS teachers in the USA, might influence students' learning of the discipline. To gain a better understanding of the current conditions of ESS education in secondary schools, in the first phase, we qualitatively examined a sample middle and high school ESS textbook to explore how the big ideas of ESS, particularly geological time, are represented.
In the second phase, we quantitatively analyzed the participating college students' conceptual understanding of geological time by comparing those who had said they had had secondary school ESS learning experience with those who did not.
Additionally, college students' perceptions on learning and teaching ESS are discussed. Findings from both the qualitative and quantitative phases indicate participating students' ESS learning experience in their secondary schools seemed to have limited or little influence on their conceptual understandings of the discipline.
We believe that these results reflect the current ESS education status, connected with the declining numbers of highly qualified ESS teachers in secondary schools.

Original contributions in the Process mining. Process mining includes the automated discovery of processes from event logs. Based on observed events e. One of the essential problems in process mining is that one cannot assume to have seen all possible At best, one has seen a representative subset. Therefore, classical synthesis techniques are not suitable as they aim at finding a model that is able to exactly reproduce the log. To address this, we propose a two-step approach.
First, using a configurable approach, a transition system is constructed. Data mining. The knowledge discovery process is as old as Homo sapiens. Until some time ago, this process was solely based on the 'natural personal' computer provided by Mother Nature. Fortunately, in recent decades the problem has begun to be solved based on the development of the Data mining technology, aided by the huge computational power of the 'artificial' computers.
Digging intelligently in different large databases, data mining aims to extract implicit, previously unknown and potentially useful information from data, since 'knowledge is power'.

The stability of the main stopes and the crown pillar of the mines has been evaluated - part of which is located below the road between Santa Eulalia and San Carles de Peralta. The stability is assessed with an empirical approach using the O index, the scaled span method and a stability graph together with a numerical approach.
Results show that the stopes of the mines are globally stable but some lack an adequate safety factor. Therefore some local reinforcements and monitoring are needed. The finite element modelling in two dimensions yields realistic results on the current stope stability and possible rock falls which have already occurred.
This paper reports research about the necessity of image making for sustainable mine developments in the Republic of Korea. One of the big risks in mining activities is mining area residents opposing mine developments and operations. Analysis of the media reports on disputes between mining companies and residents can determine causes of opposing mine developments, dispute process, and influences of disputes on processes of mining projects.
To do this, civil complaints from to and 24 media reports since on opposing mining activities are analyzed. And, to analyze difficulties of mining companies, the survey is conducted to target to mining companies. The result of analysis cited that the major reasons of anti- mining activities are environmental degradation and reduced agricultural productivity. In the past, construction-oriented, environment-unfriendly mining projects had lasted.
And while mine reclamation had been postponed in abandoned mines , mining area residents had suffered from mining pollution. So, mining area residents are highly influenced by the prejudice that mining activities are harmful to mining area communities. Current mining projects in South Korea, unlike the past mining activity, focus on minimizing environmental damage and contributing to mining area communities financially. But, in many case of disputes between mining companies and mining area residents, the both cannot reach an agreements because of the negative prejudice.
Moreover, some communities categorically refuse any mining activity. On the. Energy efficient technologies for the mining industry. Klein, B. Keevil Inst.

The measures are aimed at optimizing energy-use and efficiency in mining and processing and identifying opportunities and methods of improving this efficiency. Energy conservation in comminution and beneficiation is a primary focus of research activities at the University of British Columbia UBC. The objective is to reduce energy usage in metal mines by 20 per cent overall.
Open pit copper, gold and molybdenum mines are being targeted. Projects underway at UBC were outlined, with particular reference to energy usage, recovery and alternative energy sources; preconcentration; reducing energy usage from comminution in sorting, high pressure grinding rolls and high speed stirred mills; Hydromet; other energy efficient technologies such as control and flotation; and carbon dioxide sequestration. Studies were conducted at various mining facilities, including mines in Sudbury, Ontario.
Radio Propagation in Open-pit Mines. In this paper we present the results of an extensive measurement campaign performed at two large iron ore mining centers in Brazil at the 2. Although several studies focusing on radio propagation in underground mines have been published, measurement data and careful analyses for open Our results aim at filling this gap in the literature. The research is motivated by the ongoing mine automation initiatives, where connectivity becomes critical.
This paper presents the first set of results comprising measurements under a gamut of propagation conditions. A second The results indicate that conventional wisdom is wrong, in other words, radio-frequency RF propagation in surface mines can be far more elaborate than plain free-space line-of-sight conditions. Mining Method. The reducing coal market has been enforcing the coal industry to make exceptional rationalization and restructuring efforts since the end of the eighties.
To the competition from crude oil and natural gas has been added the growing pressure from rising wages and rising production cost as the workings get deeper. To improve the competitive position of the coal mines against oil and gas through cost reduction, studies to improve mining system have been carried out. To find fields requiring improvements most, the technologies using in Tae Bak Colliery which was selected one of long running mines were investigated and analyzed.
The mining method appeared the field needing improvements most to reduce the production cost. The present method, so-called inseam roadway caving method presently is using to extract the steep and thick seam. However, this method has several drawbacks.
To solve the problems, two mining methods are suggested for a long term and short term method respectively. Inseam roadway caving method with long-hole blasting method is a variety of the present inseam roadway caving method modified by replacing timber sets with steel arch sets and the shovel loaders with chain conveyors.
And long hole blasting is introduced to promote caving. And pillar caving method with chock supports method uses chock supports setting in the cross-cut from the hanging wall to the footwall. Two single chain conveyors are needed. One is installed in front of chock supports to clear coal from the cutting face. The other is installed behind the supports to transport caved coal from behind. This method is superior to the previous one in terms of safety from water-inrushes, production rate and productivity.
The only drawback is that it needs more investment. Rheological phenomena in focus. More than possibly any other scientific discipline, rheology is easily visualized and the relevant literature contains many excellent photographs of unusual and often bizarre phenomena. The present book brings together these photographs for the first time. They are supported by a full explanatory text. Rheological Phenomena in Focus will be an indispensable support manual to all those who teach rheology or have to convince colleagues of the practical relevance of the subject within an industrial setting.
For those who teach fluid mechanics, the book clearly illustrates the difference be. Get on your boots: preparing fourth-year medical students for a career in surgery, using a focused curriculum to teach the competency of professionalism. Few educational programs exist for medical students that address professionalism in surgery, even though this core competency is required for graduate medical education and maintenance of board certification.
Lapses in professional behavior occur commonly in surgical disciplines, with a negative effect on the operative team and patient care. Therefore, education regarding professionalism should begin early in the surgeon's formative process, to improve behavior. The goal of this project was to enhance the attitudes and knowledge of medical students regarding professionalism, to help them understand the role of professionalism in a surgical practice.
Teaching methods included lecture, small group discussion, case studies, and journal club. We assessed attitudes about professionalism with a pre-course survey and tracked effect on learning and behavior with a post-course questionnaire. We asked AIs to rate the egregiousness of 30 scenarios involving potential lapses in professionalism. A total of AIs mean age, News Corp is a network of leading companies in the worlds of diversified media, news, education, and information services Dow Jones.
