Exemplary science instructors use inquiry to tailor content to student’s learning needs; traditional textbooks treat science
as a set of facts and a rigid curriculum. Publishers now allow instructors to compile pieces of published and/or self-authored
text to make custom textbooks. This brings numerous advantages, including the ability to produce smaller, cheaper text and
added flexibility on the teaching models used. Moreover, the internet allows instructors to decentralize textbooks through
easy access to educational objects such as audiovisual simulations, individual textbook chapters, and scholarly research articles.
However, these new opportunities bring with them new problems. With educational materials easy to access, manipulate and duplicate,
it is necessary to define intellectual property boundaries, and the need to secure documents against unlawful copying and
use is paramount. Engineers are developing and enhancing information embedding technologies, including steganography, cryptography,
watermarking, and fingerprinting, to label and protect intellectual property. While these are showing their utility in securing
information, hackers continue to find loop holes in these protection schemes, forcing engineers to constantly assess the algorithms
to make them as secure as possible. As newer technologies rise, people still question whether custom publishing is desirable.
Many instructors see the process as complex, costly, and substandard in comparison to using traditional text. Publishing companies
are working to improve attitudes through advertising. What lacks is peer reviewed evidence showing that custom publishing
improves learning. Studies exploring the effect of custom course materials on student attitude and learning outcomes are a
necessary next step. 相似文献

In this study, we aimed to understand experience of students about transition from lecture mode to case study pedagogy in business management courses. Indian education system is predominantly a follower of the lecture mode of teaching from the grass-root level till graduation. Hence Indian students are relatively less familiar with the case based teaching method. In recent times, the case pedagogy has been rapidly replacing the lecture mode in higher education institutes of India, especially at the business management colleges. We conducted a grounded theory based interview of 33 post graduate students enrolled in a business school (B School) in India, which incorporated a pedagogy shift from lecture to case method during academic session 2010–2011. We found that some of the major factors which facilitated the transition process of the students to this new style of learning were previous educational background, prior work experience, course evaluation methods, institute policies and proper orientation through preparatory sessions. Our findings substantiated extant studies conducted in the context of western countries. The findings also provide a systematic analysis of the various issues in incorporating such pedagogic shifts, which may help academicians to successfully troubleshoot any problems associated with commencement of case based teaching in the Indian context. 相似文献

This paper examines the history of child-care by non-kin, “non-family” members and their representations in colonial India. It focuses primarily on Bengal and relies on several genres of literary documents. Bengal harboured the seat of the British imperial capital in the city of Calcutta until 1911 and its culture was shaped in unique ways compared with other Indian cities. Based on a reading of select literary documents such as European advice manuals and Bengali personal narratives, the paper argues that the relationship between caregivers and children in colonial households attests to the building of new ties and deep ambiguous, multi-dimensional relationships with non-kin members thereby revealing the plasticity of Indian families where sociocultural boundaries were blurred and intimate relationships forged. Beginning with the literary representation of a wet-nurse in Mahasweta Devi's short story Breast-Giver, the paper delves into the world of European and Indian accounts to recuperate the history of the caregivers. It demonstrates that despite the emphasis of recent scholars that the construction of a respectable middle-class identity was based on a sharp distinction from lower social groups, such as working women and prostitutes, the history of child-care by hired domestics reveals the sharing of a common world by different caste-class groups and the interpenetration of the two domains of culture. 相似文献

The introduction of television in conventional higher education has been experimented with worldwide since the early 1950s. Several ways of putting television to effective use in higher education have been developed. One of the successful educational projects in the developing countries is the Countrywide Classroom Project in India. The traditional educational system at all levels remains compartmentalized which makes it necessary to use new and innovative means of education. With the intention of overcoming some of the numerous obstacles to knowledge and learning in the Indian context, the University Grants Commission initiated a unique educational experiment‐‐the Countrywide Classroom‐‐in 1984. Beginning with 1 hour of telecast of Countrywide Classroom programmes on all working days in Doordarshan, India's National Public Service Television network, it has now evolved to 20 hours of telecast per week. Over a period of time, a decentralized production system, using countrywide creative talent, came into being. The Countrywide Classroom has created a niche audience of youth and adults in cities, small towns and remote areas devoid of adequate educational facilities. This paper presents a discussion of the Countrywide Classroom Project, its infrastructure, production, transmission, limitations and future directions. 相似文献

Hyperkalemia is a life threatening electrolyte derangement that must be recognized and treated quickly. Pseudohyperkalemia is defined as a difference between serum and plasma potassium concentration of more than 0.4 meq/L with serum values on the higher side when both the samples are obtained at the same time, remain at room temperature and are tested within 1 h of sample collection. Given the implication of basing medical decisions on falsely elevated potassium levels, timely identification of the entity of pseudohyperkalemia and differentiating it from true hyperkalemia becomes utmost important. Here we present a case report of a 36 year old female admitted with a provisional diagnosis of pyrexia of unknown origin with hepatosplenomegaly and anaemia under evaluation. During hospital stay her potassium levels in whole blood, serum and plasma reportedly differed significantly. An abnormal WBC count beyond assay range was reported and during subsequent investigations this lead to a peripheral smear being advised and diagnosis revealed chronic lymphoblastic leukaemia with blast crisis and 86% blast cells. In patients with leukocytosis and thrombocytosis, pseudohyperkalemia may exist in the absence of electrocardiogram changes or other clinical manifestations of true hyperkalemia thus leading to reevaluation of potassium values in serum, plasma and whole blood to arrive at the true picture. 相似文献

The purpose of this study was to assess the predictive values of central obesity and hyperandrogenemia in development of insulin resistance and dyslipidemia in the polycystic ovarian syndrome (PCOS) patients in our region. Differences of fasting blood glucose level, insulin resistance index HOMA-IR, lipid parameters, waist hip ratio (WHR), body mass index, LH/FSH ratio and testosterone levels between 45 PCOS cases and 35 age matched controls were obtained. Strength of association between different parameters in the case group was assayed by Pearson’s correlation analysis. Dependence of insulin resistance and WHR on different predictors was assessed by multiple linear regression assay. Total cholesterol, LDL cholesterol, LH, FSH, LH/FSH ratio, WHR and insulin resistance were significantly higher in the case group (p < 0.05). Serum testosterone showed strong correlation with insulin resistance and LH/FSH ratio (r = 0.432 and 0.747, p = 0.01 and 0.001 respectively) in the PCOS patients while WHR and serum testosterone level stood out to be most significant predictors for the insulin resistance (β = 0.361 and 0.498; p = 0.048 and 0.049 respectively). Hyperandrogenemia and central obesity were the major factors predicting development of insulin resistance and its related metabolic and cardiovascular complications in our PCOS patients. We suggest early monitoring for androgen level and WHR in these patients for predicting an ensuing insulin resistance and modulating the treatment procedure accordingly to minimise future cardiovascular risks. 相似文献

The effects of rheological behavior of blood and pulsatility on flow through an artery with stenosis have been investigated. Blood has been represented by a non-Newtonian fluid obeying Herschel–Bulkley equation. Using the Reynolds number as the perturbation parameter, a perturbation technique is adopted to solve the resulting quasi-steady non-linear coupled implicit system of differential equations. Analytical expressions for velocity distribution, wall shear stress, volumetric flow rate and the mean flow resistance have been obtained. It is observed that the wall shear stress and flow resistance increase for increasing value of yield stress with other parameters held fixed. One of the remarkable results of the present analysis is not only to bring out the effect of the size of the stenosis but also to study the influence of the shape of the stenosis. The change in the shape of the stenosis brings out a significant change in the value of flow resistance but it has no effect on the variation of wall shear stress except shifting the point (where it attains its maximum value) towards downstream. It is pertinent to point out that pulsatile flow of Newtonian fluid, Bingham plastic fluid and Power-law fluid become particular cases of the present model. The present approach has general validity in comparison with many mathematical models developed by others and may be applied to any mathematical model by taking into account of any type of rheological property of blood. The obtained velocity profiles have been compared with the experimental data and it is observed that blood behaves like a Herschel–Bulkley fluid rather than Power-law and Bingham fluids. Finally, some biorheological applications of the present model have briefly been discussed. 相似文献
