Abstract Objectives Understanding the issues concerning the conducting of virtual orthodontic learning sessions (VOLSs) is essential. This study aims to identify attendees- and host-related aspects that could optimise learning and uptake from the VOLSs. Methodology Fourteen pre-validated questions were anonymously and electronically sent to 3000 orthodontic residents and specialists globally. The survey included demographic questions and questions to gauge attendees' engagement, memorising, and motivation-related factors. Reminders were sent at two-week intervals to non-respondents. The survey was closed when the sample size was met. Descriptive and inferential statistics were performed. Results 593 orthodontic residents and specialists (294 males and 299 females), primarily junior orthodontists and residents aged between 25 and 35 years of age, completed the survey. Post-VOLS recording was highly requested by the participants (8.84/10, 95% CI 8.67–9.00) with no significant influence of demographics on this trend (p > 0.05). Most of the participants were in favour of short post-VOLSs feedback (6.79/10 95% CI 6.58–6.99) with significant differences (p = 0.048) between participants from different regions of the world. The average number of screenshots taken was 6.1 per lecture. The learners’ interests in attending on-line lectures were mainly to learn new clinical orthodontic tips (96.8%). Conclusion Implementing a short feedback survey after VOLSs, the provision of recording, and the provision of certificates of attendance need to be considered.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.

Tea is an imperative beverage elsewhere in the world.  The need and demand for tea are increasing day by day.  Tea Association of USA expects continued growth in tea sales due to awareness on its health benefits. There are more than 3000 kinds of tea varieties are there but only four varieties are widely used. The authors investigated the opinion on sustainability perspectives and problems faced by them while they intend to buy. Willing Participants are included in survey with the sample size of 237.  The correlation result revealed that there is a positive relationship between educational qualification and sustainability perspectives of tea products among consumers. .  It is also found that lack of information and high price were the major problems faced by tea consumers while intend to buy sustainable tea. So the tea manufacturers and processors must throw light on these issues to improve its preference among consumers.

This chapter explores the research related to whether career counselling is effective for individuals with vocational issues. In particular, there is considerable empirical support for career counselling related to career choice issues and searching for employment. Hence, practitioners can use this evidence to convince administrators, policymakers, parents, students, and other constituencies of the worth of career counselling. In addition, the chapter provides empirical evidence that practitioners can use to improve their effectiveness in working with people with career issues. This discussion mainly focuses on the results from older and newer meta-analyses regarding the ingredients that have a significant influence on effect sizes or the critical ingredients in career counselling. For example, there is considerable evidence that support from individuals, including the counsellor, may play an important role in the effectiveness of career counselling. Other factors that contribute to effective practice are also identified and discussed. The chapter further explores the need for additional research that addresses the most effective methods for providing career counselling. As the world of work becomes increasingly complex, it is important that researchers continue to explore the most effective strategies for assisting people in finding satisfying, meaningful, and productive work.

Georg Lukács

That Hegel was a significant influence on the young Georg Lukács'Theory of the Novelis a point few would dispute. Lukács himself insisted that the first part of TN represented his own transition from Kantian to Hegelian theory, and most critics have subsequently affirmed the importance of Hegel to Lukács' pre- (or, depending on one's view, proto-) Marxist argument inTN. Yet the two are in some ways strange to take together in the context of novelistic theory. Despite the profusion of novelistic literature in his own time and his own significant appropriation of it for the limning of essential moments of the development of the world-historical spirit, Hegel's officialAestheticshardly presents what one could claim to be an especially worked-outtheoryof the novel. TheAestheticstakes up literature in general primarily under the rubric of providing a theory of the genres ofpoetry— epic, lyric and dramatic — and what relatively few words Hegel actually devotes to the novel and prose literature in the lectures are tucked in corners: at the end of the discussion of the development of the epic, in the discussion of the historical form of the romantic, and in scattered comments elsewhere. As forTN, despite the strong connections some have drawn between Hegel and Lukács — Peter Demetz said that Lukács was ‘in a certain sense … the last Hegelian in the grand style’ (Demetz 1967: 215) — others have questioned whether Lukács' work should be regarded primarily as making a contribution to the philosophy of literature in the tradition from which Hegel writes.

Introduction: Toxoplasmosis is a zoonosis that represents a serious public health problem, caused by Toxoplasma gondii, which affects 20-90% of the world human population [1,2]. It is a serious problem especially when considering the congenital transmission due to congenital sequels. Treatment with highly diluted substances is one of the alternative/complementary medicines most employed in the world [3,4]. The current ethical rules regarding the number of animals used in animal experimental protocols with the use of more conservative statistical methods [5] can not enhance the biological effects of highly diluted substances observed by the experience of the researcher. Aim: To evaluate the minimum number of animals per group to achieve a significant difference among the groups of animals treated with biotherapic T. gondii and infected with the protozoan regarding the number of cysts observed in the brain. Material and methods: A blind randomized controlled trial was performed using eleven Swiss male mice, aged 57 days, divided into two groups: BIOT-200DH - treated with biotherapic (n=6) and CONTROL - treated with hydroalcoholic solution 7% (n=7).The animals of the group BIOT-200DH were treated for 3 consecutive days in a single dose 0.1ml/dose/day. The animals of BIOT – 200DH group were orally infected with 20 cysts of ME49-T. gondii. The animals of the control group were treated with cereal alcohol 7% (n=7) for 3 consecutive days and then were infected with 20 cysts of ME49 -T. gondii orally. The biotherapic 200DH T. gondii was prepared with homogenized mouse brain, with 20 cysts of T. gondii / 100μL according to the Brazilian Homeopathic Pharmacopoeia [6] in laminar flow. After 60 days post-infection the animals were killed in a chamber saturated with halothane, the brains were homogenized and resuspended in 1 ml of saline solution. Cysts were counted in 25 ml of this suspension, covered with a 24x24 mm coverglass, examined in its full length. This study was approved by the Ethics Committee for animal experimentation of the UEM - Protocol 036/2009. The data were compared using the tests Mann Whitney and Bootstrap [7] with the statistical software BioStat 5.0. Results and discussion: There was no significant difference when analyzed with the Mann-Whitney, even multiplying the "n" ten times (p=0.0618). The number of cysts observed in BIOT 200DH group was 4.5 ± 3.3 and 12.8 ± 9.7 in the CONTROL group. Table 1 shows the results obtained using the bootstrap analysis for each data changed from 2n until 2n+5, and their respective p-values. With the inclusion of more elements in the different groups, tested one by one, randomly, increasing gradually the samples, we observed the sample size needed to statistically confirm the results seen experimentally. Using 17 mice in group BIOT 200DH and 19 in the CONTROL group we have already observed statistical significance. This result suggests that experiments involving highly diluted substances and infection of mice with T. gondii should work with experimental groups with 17 animals at least. Despite the current and relevant ethical discussions about the number of animals used for experimental procedures the number of animals involved in each experiment must meet the characteristics of each item to be studied. In the case of experiments involving highly diluted substances, experimental animal models are still rudimentary and the biological effects observed appear to be also individualized, as described in literature for homeopathy [8]. The fact that the statistical significance was achieved by increasing the sample observed in this trial, tell us about a rare event, with a strong individual behavior, difficult to demonstrate in a result set, treated simply with a comparison of means or medians. Conclusion: Bootstrap seems to be an interesting methodology for the analysis of data obtained from experiments with highly diluted substances. Experiments involving highly diluted substances and infection of mice with T. gondii should be better work with experimental groups using 17 animals at least.

The Welfare State

The purpose of this study was to understand the phenomenon of entrepreneurship activity with a coherent paradigm that has not been widely explored. Entrepreneurship has been regarded as one of the important factor that support growth and socioeconomic development of a country because it can provides so many jobs, which ultimately will improve the welfare state and competitive advantage. Prior studies have been conducted research which is none of the comprehensive approach taken to explain the factors that encourage entrepreneurial activity that occurred in various countries around the world. This study found that Individualism negatively significant influence TEA which means the higher level of individualism of a country the lower Entrepeneurial activity. Moreover, cost enforcing contracts significantly influence national entrepreneurial activity which means the higher level of cost enforcing contracts the higher level of TEA.
