In this study, we explored the relationships between teachers’ self-articulated professional learning goals and their teaching experience. Although those relationships seem self-evident, in programmes for teachers’ professional development years of teaching experience are hardly taken into account. Sixteen teachers with varying years of experience and subjects were interviewed. The results show different learning goals, related to communication and organisation, curriculum and instruction, innovation, responsibilities, and themselves as professional. Various relationships between learning goals and teaching experience emerged, which clearly reflect the development from early- to mid- and late-career teachers. Issues related to curriculum and instruction appeared to be learning goals for early- and mid-career teachers. This implies that regardless of increasing teaching expertise, curriculum and instruction remain central to teachers’ continuous learning. Late-career teachers were interested in learning about extra-curricular tasks and innovations. Models of professional life phases have been used to interpret these results. 相似文献

Previous studies have shown (1) that the form of the pigeon’s conditioned keypecking response resembles that of its ingestive pecking response, (2) that both ingestive and conditioned pecking in the pigeon are compound responses, including both transport (neck-movement) and gape (jaw-movement) components, and (3) that during operant conditioning or autoshaping of pecking behavior, the gape component comes under the associative control of the CS. In the present study, the gape component was experimentally isolated and a classical conditioning paradigm (water US) was used to bring jaw movements under the control of a CS (light). The results indicate that the topography of the jaw-movement CR is very similar to, though more variable than, that of the UR. They are consistent with the hypothesis that reported similarities in the form of ingestive and conditioned pecking responses reflect, in part, classical conditioning of the gape component. 相似文献

Metabolic syndrome contributes to pathogenesis of Type-2 diabetes and CAD. Insulin Resistance is the key factor of metabolic
syndrome implicated in development of Non Alcoholic Fatty Liver Disease (NAFLD). In present study we have investigated the
prevalence of NAFLD in metabolic syndrome and contribution of metabolic risk factors in causation of NAFLD in non-diabetic
North Indian male population. The study was conducted on 495 non-diabetic, nonalcoholic subjects (age 30–65 years). Metabolic
Syndrome was assessed by using ATP III and ADA (2005) criteria. Anthropometric factors-Waist circumference and blood pressure
were measured. Fasting serum samples were analyzed for Glucose, Triglycerides, Cholesterol and its fractions, Insulin, Alanine
transaminase, Aspartate transaminase, Gamma glutamyl transferase and free fatty acids. Insulin resistance was estimated by
Homeostasis Model and Insulin sensitivity by QUICKI Index. Liver ultrasonographic scanning was used for assessing fatty liver.
The prevalence of metabolic syndrome and NAFLD was 24% and 14.8% respectively in non-alcoholic population and 27% of metabolic
syndrome had NAFLD which was associated with hyperinsulinemia, insulin resistance, insulin insensitivity along with elevated
levels of waist circumference, blood pressure, triglyceride, FFA and decreased HDL-Cholesterol. The prevalence of NAFLD increased
with insulin resistance and clustering of metabolic risk factors. 相似文献

ABSTRACTWe report on biological control of an active infestation by biscuit beetles (Stegobium paniceum) of museum objects (Old Masters paintings) in the storage facilities of the Museum of Fine Arts in Vienna. Because chemical and non-chemical treatment methods would have been very problematic, the release of parasitic wasps (Lariophagus distinguendus) was discussed and accepted by the director of the collection. We released 3000 wasps every month from August 2013 until September 2014 in the two infested storage rooms and monitored the activity of biscuit beetles on sticky blunder traps and light traps, and also by visual inspection. In the insect monitoring of 2014 until 2018 no more biscuit beetles were found in the two storage depositories, showing that the treatment was 100% successful. To our knowledge, this is the first proof of a fully successful biological control of a museum pest using parasitoids only, and also of stored product/food pest, outside a laboratory experimental setup. This biological pest control method allowed avoiding negative side effects such as contamination from treatments with biocides, or costly logistics in case of chemical-free methods. 相似文献

In this paper we present a detailed synthesis of the development of the Human Genome Project (HGP) from the mid 1980s through 2000, in order to test our hypothesis of “social bubbles”, which claims that strong social interactions between enthusiastic supporters weave a network of reinforcing feedbacks that lead to widespread endorsement and extraordinary commitment by those involved, beyond what would be rationalized by a standard cost-benefit analysis in the presence of extraordinary uncertainties and risks. The HGP was initiated as a public project funded by government agencies, starting at a moderate pace. The progressive introduction of different actors and the development of various interests catalyzed the project, which eventually became eminent both in the public and private sectors. The competition between the public and the private sector played greatly in favor of both: the financial burden as well as the horizon of the public project were significantly reduced, the private project(s) gained from the hype of the public project, yet had to play an active and collaborative role in order to remain in the game. This is at the core of the social bubble hypothesis. To further our argument, we present quantitative analysis of the development of the biotech sector within the financial stock market. Lastly, we point to the fact that the hypes fueling the bubble during its growth have not been followed by real tangible outcomes over the short expected time horizons. Indeed, at the time of writing (May, 2011), the consensus of the scientific community is that it will take decades to exploit the fruits of the HGP. 相似文献

Faculty homepage discovery is an important step toward building an academic portal. Although the general homepage finding
tasks have been well studied (e.g., TREC-2001 Web Track), faculty homepage discovery has its own special characteristics and
not much focused research has been conducted for this task. In this paper, we view faculty homepage discovery as text categorization
problems by utilizing Yahoo BOSS API to generate a small list of high-quality candidate homepages. Because the labels of these
pages are not independent, standard text categorization methods such as logistic regression, which classify each page separately,
are not well suited for this task. By defining homepage dependence graph, we propose a conditional undirected graphical model
to make joint predictions by capturing the dependence of the decisions on all the candidate pages. Three cases of dependencies
among faculty candidate homepages are considered for constructing the graphical model. Our model utilizes a discriminative
approach so that any informative features can be used conveniently. Learning and inference can be done relatively efficiently
for the joint prediction model because the homepage dependence graphs resulting from the three cases of dependencies are not
densely connected. An extensive set of experiments have been conducted on two testbeds to show the effectiveness of the proposed
discriminative graphical model. 相似文献
