The International Meetings of Early-stage Researchers in Palaeontology (IMERP) are aimed at early-stage palaeontologists, from undergraduate students to recent post-doctoral researchers. Geologists, biologists or any scientist with research topics related to palaeontology, as well as palaeoartists, are also welcome. The IMERP has two main objectives: To provide a friendly environment for early-stage researchers to present their research through oral or poster presentations and follow each other’s progress. To share new methods and ideas useful in palaeontology, and develop the skills of the attendees with the help of leading experts, invited to give lectures about their fields. The IMERPs are usually held in villages or towns located in countryside areas of geological interest. This way the meeting can be held in a closer and more friendly environment, as well as help to the dissemination of the regional natural heritage among the local population. A field trip to this paleontological and geological heritage is offered to the meeting participants. After the 1st IMERP in 2016, the 2nd IMERP was held in Sigri (Lesbos, Greece) in 2017, the 3rd IMERP in Krasiejów (Opole, Poland) in 2018, and the 4th in Cuenca (Spain) in 2019

AbstractMy research interest lies at the interaction between human-computer interaction (HCI) and geoinformatics. I am interested in developing new methods and novel user interfaces to navigate through spatial information. This article will give a brief overview on my past and current research topics and streams. Generally speaking, geography is playing an increasingly important role in computer science and also in the field of HCI ranging from social computing to natural user interfaces (NUIs). At the same time, research in geography has focused more and more on technology-mediated interaction with spatiotemporal phenomena. By bridging the two fields, my aim is to exploit this fruitful intersection between those two and develop, design and evaluate user interfaces that help people to solve their daily tasks more enjoyable and effectively.

Introduction: Maxillofacial defects are facial disfigurements resulting from congenital abnormalities, surgical resection of tumours, trauma, or a combination of these. The resulting deformity often leads to a difficult path of recovery with lifelong consequences, causing both physical disability and mental distress. Prosthetic rehabilitation is not only a solution to cover the physical deficit, but also a way to improve function as well as the quality of life for such patients. However, the knowledge amongst undergraduate dental health professionals about the same has been at sparse. Aim: To evaluate the knowledge, attitude, and practices regarding maxillofacial defects and their prosthetic rehabilitation amongst dental undergraduate students. Materials and Methods: A cross-sectional survey was conducted between January 2020 and June 2020, amidst the third year, fourth year undergraduate students, and interns of Belagavi city, Karnataka, India. The data was collected using a 16-item custom designed proforma, comprising of questions evaluating student’s basic knowledge about the diagnosis, treatment procedures, and treatment planning of maxillofacial defects and their prosthetic rehabilitation. Statistical analysis was done using Chi-square test in each group, using SPSS version 22 p-value <0.05 to be considered significant. Results: A total of 286 participants answered the questionnaire, of which 117 (40.9%) were interns, 116 (40.6%) were third year students, and 53 (18.5%) were fourth year students. 279 (97.6%) participants had an understanding regarding maxillofacial defects. Of those who had witnessed cases, only 18.2% had observed more than three cases (p-value <0.001). Out of respondents with treatment understanding, 184 (64.3%) answered that it required a multidisciplinary approach (p-value <0.001). 197 (68.9%) of the respondents felt that silicone was the most commonly used material (p<0.003). 165 (57.7%) answered that waxes were the most commonly used impression material (p-value <0.001). Out of the respondents awared about treatment modalities, 120 (42%) respondents majority answered that CAD-CAM would contribute the most to maxillofacial rehabilitation. Conclusion: Comprehensive understanding and clinical application of prosthodontic rehabilitation of maxillofacial defects among undergraduate students was found to be lacking. This awareness should be initiated at an early stage of the clinical training for undergraduate training programme, as it will help to understand the basic aspects involved in the prosthodontic rehabilitation of maxillofacial defects.

This volume summarizes the present status of research in the field of organic and inorganic boron chemistry, presented by the invited speakers at the 12th International Meeting on Boron Chemistry (IMEBORON-XII), held in Sendai, Japan, 11-15 September 2005. IMEBORON-XII consisted of 1 plenary lecture, 22 invited lectures, 24 keynote lectures, 48 short oral presentations, and 99 poster presentations. In all, 280 chemists contributed to a truly international meeting, with participants representing China, Czech Republic, Germany, Israel, Japan, Mexico, Poland, Russia, South Korea, Spain, Sweden, the United Kingdom, and the United States.The presentations at IMEBORON-XII covered all aspects of boron chemistry including theoretical studies, synthetic methods of organic and inorganic boron compounds, novel molecular structures, application of organic and inorganic boron compounds to organic synthesis as catalysts or as reagents, medicinal applications, and creation of new materials (liquid crystals, supramolecular clusters, nanocylinders, molecular electronic devices, nanomachines, ceramics, etc.). Not only the distinguished senior members of the boron community, but also young boron chemists took an active part in the conference. Not only traditional boron chemistry, but also new evolving research areas of boron chemistry were presented. Accordingly, I feel that a new generation of both researchers and research fields is coming in boron chemistry. A selection of the invited contributions to IMEBORON-XII is presented in the 14 papers in this issue.The importance of scientific exchange in this field was recognized during IMEBORON-XII. Therefore, the continuation of this series of conferences was discussed, and the venue for IMEBORON-XIII in 2008 will be organized by Prof. F. Teixidor at the Institut de Ciencia de Materials de Barcelona, C.S.I.S., Campus U.A.B., Ballaterra, Spain.Yoshinori YamamotoChairman of IMEBORON-XII

e19536 Background: Prognosis of patients with Hodgkin lymphoma (HL) has substantially improved but therapy of HL can however contribute to delayed toxicity. Long term treatment outcomes of HL in our local population were evaluated. Methods: Clinical and treatment data was prospectively collected from all patients with a histological diagnosis of HL. Patients were all fully staged with CT scan and bone marrow biopsy. Results: On the basis of 217 patients seen at the National Cancer Centre Singapore between 1990–2008, we found that there was a peak in young adulthood with 103 patients who were diagnosed before the age of 30 (48%), median age of presentation 32 (range 17–84). Patients who were young (< 30 years) were more likely to present with nodular sclerosis HL (p=0.0001). Treatment outcomes were comparable to other published series, 85% of cases received ABVD based treatment. 5 year OS for early stage HL was 92% and 88% for advanced stage HL. Overall FFTF was 93% at 5 years. Of note, comparing patients with early stage (Stage I/ II) HL (n=114) who had ABVD 4 cycles followed by involved field radiotherapy (IFRT) with those who received 6–8 cycles of ABVD, there was no difference in OS, FFTF (p= 0.99, 0.48 respectively). Bulky early stage HL who received 6 cycles of ABVD and IFRT had better FFTF rates than those who had just 4 cycles of ABVD followed by IFRT (p=0.06). In contrast, patients patients with advanced HL (Stage III/ IV) (n=70) who completed 6–8 cycles of ABVD did not benefit from additional IFRT even in the presence of bulky disease (n=15). Acute toxicities included that of bleomycin induced pneumonitis (BIP) seen in 15% of cases. Neither the omission of bleomycin nor the presence BIP adversely affected treatment outcomes. Hematological malignancies were seen in 1% of survivors appearing after a median of 7.3 years. Hypothyroidism was noted in 3% of cases. Conclusions: 1) Epidemiology of HL in Singapore is increasingly similar to that of developed countries with a peak in young adults. 2)Young age was predictive of a nodular sclerosis subtype 3) Abbreviated chemotherapy using 4 cycles of ABVD followed by IFRT performed similarly to 6 cycles of ABVD in early stage HL, but in patients with bulky disease this may not be sufficient. 4) BIP occurred in 15% of cases. BIP and the omission of bleomycin did not adversely affect treatment outcomes. No significant financial relationships to disclose.

Background and Aims. Small gastric or colorectal tumours can be visually undetectable during laparoscopic surgeries, and available methods still do not provide a 100% localisation rate. Thus, new methods for further improvements in tumour localisation are highly desirable. In this study, we evaluated the usage of the Medical Tactile Endosurgical Complex (MTEC) in gastrointestinal surgery for localisation of tumours. The MTEC provides the possibility of instrumental mechanoreceptoric palpation, which serves as an analogue of conventional manual palpation.Methods. Ninety-six elective surgeries were performed, including 48 open surgeries, 43 laparoscopies, and 5 robot-assisted surgeries. The 20 mm version of the MTEC tactile mechanoreceptor was used in open surgeries, and the 10 mm version in laparoscopic and robot-assisted surgeries.Results. The mean time of instrumental mechanoreceptoric palpation was 3 minutes 12 seconds for open surgeries, which constituted the early stage of the learning curve, and 3 minutes 34 seconds for laparoscopic surgeries. No side effects or postoperative complications related to instrumental mechanoreceptoric palpation were observed, and this procedure provided data sufficient for tumour localisation in more than 95% of cases.Conclusion. Instrumental mechanoreceptoric palpation performed using MTEC is a simple, safe, and reliable method for tumour localisation in gastrointestinal laparoscopic surgery.

Background Decisions about new health technologies are increasingly being made while trials are still in an early stage, which may result in substantial uncertainty around key decision drivers such as estimates of life expectancy and time to disease progression. Additional data collection can reduce uncertainty, and its value can be quantified by computing the expected value of sample information (EVSI), which has typically been described in the context of designing a future trial. In this article, we develop new methods for computing the EVSI of extending an existing trial’s follow-up, first for an assumed survival model and then extending to capture uncertainty about the true survival model. Methods We developed a nested Markov Chain Monte Carlo procedure and a nonparametric regression-based method. We compared the methods by computing single-model and model-averaged EVSI for collecting additional follow-up data in 2 synthetic case studies. Results There was good agreement between the 2 methods. The regression-based method was fast and straightforward to implement, and scales easily included any number of candidate survival models in the model uncertainty case. The nested Monte Carlo procedure, on the other hand, was extremely computationally demanding when we included model uncertainty. Conclusions We present a straightforward regression-based method for computing the EVSI of extending an existing trial’s follow-up, both where a single known survival model is assumed and where we are uncertain about the true survival model. EVSI for ongoing trials can help decision makers determine whether early patient access to a new technology can be justified on the basis of the current evidence or whether more mature evidence is needed. Highlights Decisions about new health technologies are increasingly being made while trials are still in an early stage, which may result in substantial uncertainty around key decision drivers such as estimates of life-expectancy and time to disease progression. Additional data collection can reduce uncertainty, and its value can be quantified by computing the expected value of sample information (EVSI), which has typically been described in the context of designing a future trial. In this article, we have developed new methods for computing the EVSI of extending a trial’s follow-up, both where a single known survival model is assumed and where we are uncertain about the true survival model. We extend a previously described nonparametric regression-based method for computing EVSI, which we demonstrate in synthetic case studies is fast, straightforward to implement, and scales easily to include any number of candidate survival models in the EVSI calculations. The EVSI methods that we present in this article can quantify the need for collecting additional follow-up data before making an adoption decision given any decision-making context.

The ability to recognise new research trends early is strategic for many stakeholders, such as academics, institutional funding bodies, academic publishers and companies. While the state of the art presents several works on the identification of novel research topics, detecting the emergence of a new research area at a very early stage, i.e., when the area has not been even explicitly labelled and is associated with very few publications, is still an open challenge. This limitation hinders the ability of the aforementioned stakeholders to timely react to the emergence of new areas in the research landscape. In this paper, we address this issue by hypothesising the existence of an embryonic stage for research topics and by suggesting that topics in this phase can actually be detected by analysing diachronically the co-occurrence graph of already established topics. To confirm our hypothesis, we performed a study of the dynamics preceding the creation of novel topics. This analysis showed that the emergence of new topics is actually anticipated by a significant increase of the pace of collaboration and density in the co-occurrence graphs of related research areas. These findings are very relevant to a number of research communities and stakeholders. Firstly, they confirm the existence of an embryonic phase in the development of research topics and suggest that it might be possible to perform very early detection of research topics by taking into account the aforementioned dynamics. Secondly, they bring new empirical evidence to related theories in Philosophy of Science. Finally, they suggest that significant new topics tend to emerge in an environment in which previously less interconnected research areas start cross-fertilising.

Most horticultural students at Fort Valley State College (1890 land grant college) have little or no background in aspects of horticultural marketing. We offer a course in Marketing Technology to address this lack of background in horticultural marketing. In this course, students learn how to obtain a business license and a tax number. The significance of financial planning is stressed through practice. Students learn the strategies involved in merchandising and pricing, the proper display techniques, and the importance of advertising. Field-trips to local horticultural businesses allow for students to interact with professionals in horticulture. Students are required to do reports on each field-trip taken in the course.

When it comes to basic rights of the fetus, including the right to life, theoretical studies around the world on human rights of the fetus still have not reached an agreement on approaches and explanation. Criminal law at the international and national levels still leaves the possibility of protecting the unborn child. Viet Nam’s criminal law is no exception to this trend. In addition, Viet Nam is currently facing human trafficking with new methods and tricks. Children are bought and paid for while still in the womb, then born abroad and given to traffickers. Children are only protected by criminal law for human trafficking if they are born, alive, and detected by the authorities. While the act of trafficking in fetuses is often easily detected by the authorities right from the stage of purchasing and paying, it is not feasible to prosecute this act for human trafficking under the criminal law of Viet Nam. This reduces the criminal law’s ability to suppress crime, at the same time, leaves many fetuses unprotected. Should criminal law be left outside the legal mechanism to protect children while in the fetal stage? This article suggests considering fetus trafficking as a form of human trafficking and to criminalize fetus trafficking. Criminal law should recognize fetus trafficking as a sign of crime or an early stage in the criminal process of human trafficking, because children need special care and protection, including appropriate legal protection before and after birth, due to their physical and mental immaturity.
