Providing public information is one of the main activities of The Nuclear Training Centre (ICJT) at the Jozef Stefan Institute. Our primary target is students of primary and secondary schools. The lecture they listen to during their visit to our centre was old fashioned since we used classic overhead projector. We have modernized it with an LCD projector and computer-based interactive presentation in order to improve students' comprehension. (author)

A transcriptional regulator, Hes1, plays crucial roles in the control of differentiation and proliferation of neuronal, endocrine, and T-lymphocyte progenitors during development. Mechanisms for the regulation of cell proliferation by Hes1, however, remain to be verified. In embryonic carcinoma cells, endogenous Hes1 expression was repressed by retinoic acid in concord with enhanced p27Kip1 expression and cell cycle arrest. Conversely, conditional expression of a moderate but not maximal level of Hes1 in HeLa cells by a tetracycline-inducible system resulted in reduced p27Kip1 expression, which was attributed to decreased basal transcript rather than enhanced proteasomal degradation, with concomitant increases in the growth rate and saturation density. Hes1 induction repressed the promoter activity of a 5′ flanking basal enhancer region of p27Kip1 gene in a manner dependent on Hes1 expression levels, and this was mediated by its binding to class C sites in the promoter region. Finally, hypoplastic fetal thymi, as well as livers and brains of Hes1-deficient mice, showed significantly increased p27Kip1 transcripts compared with those of control littermates. These results have suggested that Hes1 directly contributes to the promotion of progenitor cell proliferation through transcriptional repression of a cyclin-dependent kinase inhibitor, p27Kip1.

Full Text Available Abstract Background p27Kip1 plays a major role as a negative regulator of the cell cycle. The regulation of p27Kip1 degradation is mediated by its specific ubiquitin ligase subunits S-phase kinase protein (Skp 2 and cyclin-dependent kinase subunit (Cks 1. However, little is known regarding the prognostic utility of p27Kip1, Skp2 and Cks1 expression in renal cell carcinoma. Methods Immunohistochemistry was performed for p27Kip1, Skp2 and Cks1 in tissue microarrays of 482 renal cell carcinomas with follow-up. The data were correlated with clinicopathological features. The univariate and multivariate survival analyses were also performed to determine their prognostic significance. Results Immunoreactivity of p27Kip1, Skp2 and Cks1 was noted in 357, 71 and 82 patients, respectively. Skp2 and Cks1 expression were not noted in chromophobe cancers. A strong correlation was found between Skp2 and Cks1 expression (P Kip1 levels (P = 0.006 and P Kip1 expression and Skp2 expression were correlated with larger tumor size and higher stage, as well as tumor necrosis. Cks1 expression was only correlated with tumor size. In univariate analysis, low p27Kip1 expression, Skp2 and Cks1 expression were all associated with a poor prognosis, while in multivariate analysis, only low p27Kip1 expression were independent prognostic factors for both cancer specific survival and recurrence-free survival in patients with RCC. Conclusion Our results suggest that immunohistochemical expression levels of p27Kip1, Skp2 and Cks1 may serve as markers with prognostic value in renal cell carcinoma.

Cyclin-dependent kinases (CDKs) and cyclins, their regulatory subunits, govern cell-cycle progression in eukaryotic cells. Kip1/p27 is the main cyclin-dependent kinase inhibitor, which arrests cell division inhibiting G1-S transition. Kip1/p27 seems to play a critical role in the pathogenesis of several human malignancies and its lower expression has been shown to correlate with a poor prognosis in adult solid tumors. Bone marrow blasts from 49 children with leukemia, 37 acute lymphoblastic leukemia (ALL), and 12 acute myeloid leukemia (AML) were studied. Exon 3 of Kip1/p27 was amplified using the polymerase chain reaction technique (PCR). Single strand conformational polymorphism and heterodouplex analysis were performed to detect DNA sequence with altered conformations and were subsequently sequenced to document mutations. Mutations in Kip1/p27 gene were detected in 2 out of 3 T-ALL, 6 out of 12 AML patients, and only 1 out of 34 B lineage ALL cases. Although the patient groups are small, a highly significant relation of the mutation status with the type of leukemia (P = 0.0037) and the risk group according to treatment protocols (P = 0.00021) was estimated. A statistically significant difference in the white blood count was observed (P = 0.019) between the mutated and non-mutated patient groups although no statistically significant association of the mutation status with the hemoglobin and platelets values, karyotype, age, sex, disease progression, and outcome was determined. Based upon these results, the Kip1/p27 mutations should be considered for further prospective testing as an additional parameter for risk stratification and treatment of childhood leukemia.

Ubiquitin-mediated degradation of the cyclin-dependent kinase inhibitor p27 Kip1 was shown to be required for the activation of key cyclin-dependent kinases, thereby triggering the onset of DNA replication and cell cycle progression. Although the SCF Skp2 ubiquitin ligase has been reported to mediate p27 Kip1 degradation, the nature of the human ubiquitin-conjugating enzyme involved in this process has not yet been determined at the cellular level. Here, we show that antisense oligonucleotides targeting the human ubiquitin-conjugating enzyme Cdc34 downregulate its expression, inhibit the degradation of p27 Kip1 , and prevent cellular proliferation. Elevation of p27 Kip1 protein level is found to be the sole requirement for the inhibition of cellular proliferation induced upon downregulation of Cdc34. Indeed, reducing the expression of p27 Kip1 with a specific antisense oligonucleotide is sufficient to reverse the anti-proliferative phenotype elicited by the Cdc34 antisense. Furthermore, downregulation of Cdc34 is found to specifically increase the abundance of the SCF Skp2 ubiquitin ligase substrate p27 Kip1 , but has no concomitant effect on the level of IkBα and β-catenin, which are known substrates of a closely related SCF ligase

It was reported recently that resveratrol could sensitize a number of cancer cells to the antitumoral effects of some conventional chemotherapy drugs. The current study was designed to investigate whether resveratrol could sensitize leukemic cells to proteasome inhibitors. Leukemic cells were treated with MG132 alone or in combination with resveratrol. Cell viability was investigated using MTT assay, and induction of apoptosis and cell cycle distribution was measured using flow cytometry. Western blot and real-time RT-PCR were used to investigate the expression of FOXO1 and p27 Kip1 . CHIP was performed to investigate the binding of FOXO1 to the p27 Kip1 promoter. Resveratrol strongly reduced cytotoxic activities of proteasome inhibitors against leukemic cells. MG132 in combination with resveratrol caused cell cycle blockade at G1/S transition via p27 Kip1 accumulation. Knockdown of p27 Kip1 using siRNA dramatically attenuated the protective effects of resveratrol on cytotoxic actions of proteasome inhibitors against leukemic cells. Resveratrol induced FOXO1 expression at the transcriptional level, while MG132 increased nuclear distribution of FOXO1. MG132 in combination with resveratrol caused synergistic induction of p27 Kip1 through increased recruitment of FOXO1 on the p27 Kip1 promoter. Resveratrol may have the potential to negate the cytotoxic effects of proteasome inhibitors via regulation of FOXO1 transcriptional activity and accumulation of p27 Kip1

Full Text Available Vitamin E δ-tocotrienol has been shown to have antitumor activity, but the precise molecular mechanism by which it inhibits the proliferation of cancer cells remains unclear. Here, we demonstrated that δ-tocotrienol exerted significant cell growth inhibition pancreatic ductal cancer (PDCA cells without affecting normal human pancreatic ductal epithelial cell growth. We also showed that δ-tocotrienol-induced growth inhibition occurred concomitantly with G(1 cell-cycle arrest and increased p27(Kip1 nuclear accumulation. This finding is significant considering that loss of nuclear p27(Kip1 expression is a well-established adverse prognostic factor in PDCA. Furthermore, δ-tocotrienol inactivated RAF-MEK-ERK signaling, a pathway known to suppress p27(Kip1 expression. To determine whether p27(Kip1 induction is required for δ-tocotrienol inhibition of PDCA cell proliferation, we stably silenced the CDKN1B gene, encoding p27(Kip1, in MIAPaCa-2 PDCA cells and demonstrated that p27(Kip1 silencing suppressed cell-cycle arrest induced by δ-tocotrienol. Furthermore, δ-tocotrienol induced p27(Kip1 mRNA expression but not its protein degradation. p27(Kip1 gene promoter activity was induced by δ-tocotrienol through the promoter's E2F-1 binding site, and this activity was attenuated by E2F-1 depletion using E2F-1 small interfering RNA. Finally, decreased proliferation, mediated by Ki67 and p27(Kip1 expression by δ-tocotrienol, was confirmed in vivo in a nude mouse xenograft pancreatic cancer model. Our findings reveal a new mechanism, dependent on p27(Kip1 induction, by which δ-tocotrienol can inhibit proliferation in PDCA cells, providing a new rationale for p27(Kip1 as a biomarker for δ-tocotrienol efficacy in pancreatic cancer prevention and therapy.

Cholangiocarcinoma is a deadly disease which responds poorly to surgery and conventional chemotherapy or radiotherapy. Early diagnosis is difficult due to the anatomical and biological characteristics of cholangiocarcinoma. Cyclin-dependent kinase inhibitor 1B (p27Kip1) is a cyclin‑dependent kinase inhibitor and in the present study, we found that p27Kip1 expression was suppressed in the nucleus and increased in the cytoplasm in 53 samples of cholangiocarcinoma from patients with highly malignant tumors (poorly-differentiated and tumor-node-metastsis (TNM) stage III-IV) compared with that in samples from 10 patients with chronic cholangitis. The expression of phosphorylated (p-)p27Kip1 (Ser10), one of the phosphorylated forms of p27Kip1, was increased in the patient samples with increasing malignancy and clinical stage. Coincidentally, chromosome region maintenance 1 (CRM-1; also referred to as exportin 1 or Xpo1), a critical protein responsible for protein translocation from the nucleus to the cytoplasm, was also overexpressed in the tumor samples which were poorly differentiated and of a higher clinical stage. Through specific short hairpin RNA (shRNA)-mediated knockdown of CRM-1 in the cholangiocarcinoma cell line QBC939, we identified an elevation of cytoplasmic p27Kip1 and a decrease of nuclear p27Kip1. Furthermore, the viability and colony formation ability of QBC939 cells was largely reduced with G1 arrest. Consistent with the findings of the in vitro experiments, in a xenograft mouse model, the tumors formed in the CRM-1 knockdown group were markedly smaller and weighed less than those in the control group in vivo. Taken together, these findings demonstrated that the interplay between CRM-1 and p27Kip1 may provide potentially potent biomarkers and functional targets for the development of future cholangiocarcinoma treatments.

p27Kip1 Is Required to Mediate a G1 Cell Cycle Arrest Downstream of ATM following Genotoxic Stress.

Full Text Available The DNA damage response (DDR is a coordinated signaling network that ensures the maintenance of genome stability under DNA damaging stress. In response to DNA lesions, activation of the DDR leads to the establishment of cell cycle checkpoints that delay cell-cycle progression and allow repair of the defects. The tumor suppressor p27Kip1 is a cyclin-CDK inhibitor that plays an important role in regulating quiescence in a variety of tissues. Several studies have suggested that p27Kip1 also plays a role in the maintenance of genomic integrity. Here we demonstrate that p27Kip1 is essential for the establishment of a G1 checkpoint arrest after DNA damage. We also uncovered that ATM phosphorylates p27Kip1 on a previously uncharacterized residue (Ser-140, which leads to its stabilization after induction of DNA double-strand breaks. Inhibition of this stabilization by replacing endogenous p27Kip1 with a Ser-140 phospho-mutant (S140A significantly sensitized cells to IR treatments. Our findings reveal a novel role for p27Kip1 in the DNA damage response pathway and suggest that part of its tumor suppressing functions relies in its ability to mediate a G1 arrest after the induction of DNA double strand breaks.

Histone Deacetylase Inhibitors Increase p27Kip1 by Affecting Its Ubiquitin-Dependent Degradation through Skp2 Downregulation

Full Text Available Histone deacetylase inhibitors (HDACIs represent an intriguing class of pharmacologically active compounds. Currently, some HDACIs are FDA approved for cancer therapy and many others are in clinical trials, showing important clinical activities at well tolerated doses. HDACIs also interfere with the aging process and are involved in the control of inflammation and oxidative stress. In vitro, HDACIs induce different cellular responses including growth arrest, differentiation, and apoptosis. Here, we evaluated the effects of HDACIs on p27Kip1, a key cyclin-dependent kinase inhibitor (CKI. We observed that HDACI-dependent antiproliferative activity is associated with p27Kip1 accumulation due to a reduced protein degradation. p27Kip1 removal requires a preliminary ubiquitination step due to the Skp2-SCF E3 ligase complex. We demonstrated that HDACIs increase p27Kip1 stability through downregulation of Skp2 protein levels. Skp2 decline is only partially due to a reduced Skp2 gene expression. Conversely, the protein decrease is more profound and enduring compared to the changes of Skp2 transcript. This argues for HDACIs effects on Skp2 protein posttranslational modifications and/or on its removal. In summary, we demonstrate that HDACIs increase p27Kip1 by hampering its nuclear ubiquitination/degradation. The findings might be of relevance in the phenotypic effects of these compounds, including their anticancer and aging-modulating activities.

This paper describes a teaching experiment designed to examine the learning (i.e., retention of content and conceptual development) that takes place when public scientific web lectures delivered by scientists are utilized to present advanced ideas in physics to students with a high school background in physics. The students watched an exemplary public physics web lecture that was followed by a collaborative generic activity session. The collaborative session involved a guided critical reconstruction of the main arguments in the lecture, and a processing of the key analogical explanations. Then the students watched another exemplary web lecture on a different topic. The participants (N=14) were divided into two groups differing only in the order in which the lectures were presented. The students’ discussions during the activities show that they were able to reason and demonstrate conceptual progress, although the physics ideas in the lectures were far beyond their level in physics. The discussions during the collaborative session contributed significantly to the students’ understanding. We illustrate this point through an analysis of one of these discussions between two students on an analogical explanation of the Aharonov-Bohm effect that was presented in one of the lectures. The results from the tests that were administered to the participants several times during the intervention further support this contention.

Full Text Available Background. Enhanced expression of cell cycle inhibitor p27kip1 suppresses cell proliferation. Ursodeoxycholic acid (UDCA delays progression of primary biliary cirrhosis (PBC but its effect on p27kip1 expression is uncertain. Aims. To analyze the expression of p27kip1 and its transcription modulator FoxO1 in patients with PBC, and to assess the impact of UDCA on this pathway. Materials and Methods. The examined human tissue included explanted livers from patients with cirrhotic PBC (n=23, primary sclerosing cholangitis (PSC; n=9, alcoholic liver disease (ALD; n=9, and routine liver biopsies from patients with non-cirrhotic PBC (n=26. Healthy liver samples served as controls (n=19. Livers of FoxO-deficient mice were also studied. mRNA and protein expressions were analyzed by real-time PCR and Western blot. Results. p27kip1 expression was increased in cirrhotic and non-cirrhotic PBC. FoxO1 mRNA levels were increased in PBC (8.5-fold increase versus controls. FoxO1 protein expression in PBC was comparable to controls, but it was decreased in patients with PSC and ALD (63% and 70% reduction, respectively; both P<0.05 versus control. UDCA-treated non-cirrhotic patients with PBC showed decreased expression of p27kip1 mRNA. Conclusion. PBC progression is characterized by a FoxO1-independent increase of p27kip1 expression. In early PBC, UDCA may enhance liver regeneration via p27kip1-dependent mechanism.

Feynman Lectures on Gravitation

Borcherds, P

2003-01-01

In the early 1960s Feynman lectured to physics undergraduates and, with the assistance of his colleagues Leighton and Sands, produced the three-volume classic Feynman Lectures in Physics. These lectures were delivered in the mornings. In the afternoons Feynman was giving postgraduate lectures on gravitation. This book is based on notes compiled by two students on that course: Morinigo and Wagner. Their notes were checked and approved by Feynman and were available at Caltech. They have now been edited by Brian Hatfield and made more widely available. The book has a substantial preface by John Preskill and Kip Thorne, and an introduction entitled 'Quantum Gravity' by Brian Hatfield. You should read these before going on to the lectures themselves. Preskill and Thorne identify three categories of potential readers of this book. 1. Those with a postgraduate training in theoretical physics. 2. 'Readers with a solid undergraduate training in physics'. 3. 'Admirers of Feynman who do not have a strong physics background'. The title of the book is perhaps misleading: readers in category 2 who think that this book is an extension of the Feynman Lectures in Physics may be disappointed. It is not: it is a book aimed mainly at those in category 1. If you want to get to grips with gravitation (and general relativity) then you need to read an introductory text first e.g. General Relativity by I R Kenyon (Oxford: Oxford University Press) or A Unified Grand Tour of Theoretical Physics by Ian D Lawrie (Bristol: IoP). But there is no Royal Road. As pointed out in the preface and in the introduction, the book represents Feynman's thinking about gravitation some 40 years ago: the lecture course was part of his attempts to understand the subject himself, and for readers in all three categories it is this that makes the book one of interest: the opportunity to observe how a great physicist attempts to tackle some of the hardest challenges of physics. However, the book was written 40

Objective: To analyze the effect of X-irradiation on the proteins expression of p57 kip2 and TGF-β1 in lung cancer cell stain A549 and its clinical significance. Methods: Lung cancer cell stain A549 was cultivated and cell, protein was extracted at 6,12,24,36 and 48 hours after X-irradiation by different doses(2,4, 8 and 12 Gy). The expression of p57 kip2 and TGF-β1 proteins were examined by Western blot. Results: The expression of p57 kip2 in lung cancer cell stain A549 was very low before X-irradiation, and increased significantly after irradiation with different doses and reached the peak level at 12 hours after irradiation (P kip2 and TGF-β1 proteins which increased with certain doses, p57 kip2 and TGF-β1 could be used to predict the damage degree of cancer cells by X-ray.

Loss of function of Saccharomyces cerevisiae kinesin-related CIN8 and KIP1 is suppressed by KAR3 motor domain mutations.

The kinesin-related products of the CIN8 and KIP1 genes of Saccharomyces cerevisiae redundantly perform an essential function in mitosis. The action of either gene-product is required for an outwardly directed force that acts upon the spindle poles. We have selected mutations that suppress the temperature-sensitivity of a cin8-temperature-sensitive kip1-delta strain. The extragenic suppressors analyzed were all found to be alleles of the KAR3 gene. KAR3 encodes a distinct kinesin-related protein whose action antagonizes Cin8p/Kip1p function. All seven alleles analyzed were altered within the region of KAR3 that encodes the putative force-generating (or "motor") domain. These mutations also suppressed the inviability associated with the cin8-delta kip1-delta genotype, a property not shared by a deletion of KAR3. Other properties of the suppressing alleles revealed that they were not null for function. Six of the seven were unaffected for the essential karyogamy and meiosis properties of KAR3 and the seventh was dominant for the suppressing trait. Our findings suggest that despite an antagonistic relationship between Cin8p/Kip1p and Kar3p, aspects of their mitotic roles may be similar.

The cell cycle inhibitor p27Kip¹ controls self-renewal and pluripotency of human embryonic stem cells by regulating the cell cycle, Brachyury and Twist.

The continued turn over of human embryonic stem cells (hESC) while maintaining an undifferentiated state is dependent on the regulation of the cell cycle. Here we asked the question if a single cell cycle gene could regulate the self-renewal or pluripotency properties of hESC. We identified that the protein expression of the p27(Kip)¹ cell cycle inhibitor is low in hESC cells and increased with differentiation. By adopting a gain and loss of function strategy we forced or reduced its expression in undifferentiating conditions to define its functional role in self-renewal and pluripotency. Using undifferentiation conditions, overexpression of p27(Kip)¹ in hESC lead to a G₁phase arrest with an enlarged and flattened hESC morphology and consequent loss of self-renewal ability. Loss of p27(Kip)¹ caused an elongated/scatter cell-like phenotype involving up-regulation of Brachyury and Twist gene expression. We demonstrate the novel finding that p27(Kip)¹ protein occupies the Twist1 gene promoter and manipulation of p27(Kip)¹ by gain and loss of function is associated with Twist gene expression changes. These results define p27(Kip)¹ expression levels as critical for self-renewal and pluripotency in hESC and suggest a role for p27(Kip)¹ in controlling an epithelial to mesenchymal transition (EMT) in hESC.

Accelerated turnover of taste bud cells in mice deficient for the cyclin-dependent kinase inhibitor p27Kip1

Full Text Available Abstract Background Mammalian taste buds contain several specialized cell types that coordinately respond to tastants and communicate with sensory nerves. While it has long been appreciated that these cells undergo continual turnover, little is known concerning how adequate numbers of cells are generated and maintained. The cyclin-dependent kinase inhibitor p27Kip1 has been shown to influence cell number in several developing tissues, by coordinating cell cycle exit during cell differentiation. Here, we investigated its involvement in the control of taste cell replacement by examining adult mice with targeted ablation of the p27Kip1 gene. Results Histological and morphometric analyses of fungiform and circumvallate taste buds reveal no structural differences between wild-type and p27Kip1-null mice. However, when examined in functional assays, mutants show substantial proliferative changes. In BrdU incorporation experiments, more S-phase-labeled precursors appear within circumvallate taste buds at 1 day post-injection, the earliest time point examined. After 1 week, twice as many labeled intragemmal cells are present, but numbers return to wild-type levels by 2 weeks. Mutant taste buds also contain more TUNEL-labeled cells and 50% more apoptotic bodies than wild-type controls. In normal mice, p27 Kip1 is evident in a subset of receptor and presynaptic taste cells beginning about 3 days post-injection, correlating with the onset of taste cell maturation. Loss of gene function, however, does not alter the proportions of distinct immunohistochemically-identified cell types. Conclusions p27Kip1 participates in taste cell replacement by regulating the number of precursor cells available for entry into taste buds. This is consistent with a role for the protein in timing cell cycle withdrawal in progenitor cells. The equivalence of mutant and wild-type taste buds with regard to cell number, cell types and general structure contrasts with the hyperplasia

Cyclin-dependent kinase inhibitors, p21 Cip1 and p27 Kip1 , are upregulated during vascular cell proliferation and negatively regulate growth of vascular cells. We hypothesized that absence of either p21 Cip1 or p27 Kip1 in apolipoprotein E (apoE)-deficiency may increase atherosclerotic plaque formation. Compared to apoE -/- aortae, both apoE -/- /p21 -/- and apoE -/- /p27 -/- aortae exhibited significantly more atherosclerotic plaque following a high-cholesterol regimen. This increase was particularly observed in the abdominal aortic regions. Deficiency of p27 Kip1 accelerated plaque formation significantly more than p21 -/- in apoE -/- mice. This increased plaque formation was in parallel with increased intima/media area ratios. Deficiency of p21 Cip1 and p27 Kip1 accelerates atherogenesis in apoE -/- mice. These findings have significant implications for our understanding of the molecular basis of atherosclerosis associated with excessive proliferation of vascular cells.

Salivary protein histatin 3 regulates cell proliferation by enhancing p27{sup Kip1} and heat shock cognate protein 70 ubiquitination

Histatins are salivary proteins with antimicrobial activities. We previously reported that histatin 3 binds to heat shock cognate protein 70 (HSC70), which is constitutively expressed, and induces DNA synthesis stimulation and promotes human gingival fibroblast (HGF) survival. However, the underlying mechanisms of histatin 3 remain largely unknown. Here, we found that the KRHH sequence of histatin 3 at the amino acid positions 5–8 was essential for enhancing p27{sup Kip1} (a cyclin-dependent kinase inhibitor) binding to HSC70 that occurred in a dose-dependent manner; histatin 3 enhanced the binding between p27{sup Kip1} and HSC70 during the G{sub 1}/S transition of HGFs as opposed to histatin 3-M(5–8) (substitution of KRHH for EEDD in histatin 3). Histatin 3, but not histatin 3-M(5–8), stimulated DNA synthesis and promoted HGF survival. Histatin 3 dose-dependently enhanced both p27{sup Kip1} and HSC70 ubiquitination, whereas histatin 3-M(5–8) did not. These findings provide further evidence that histatin 3 may be involved in the regulation of cell proliferation, particularly during G{sub 1}/S transition, via the ubiquitin–proteasome system of p27{sup Kip1} and HSC70. - Highlights: • KRHH amino acid sequence was required in histatin 3 to bind HSC70. • Histatin 3 enhanced HSC70 binding to p27{sup Kip1} during the G{sub 1}/S transition in HGFs. • KRHH sequence stimulated DNA synthesis and promoted cell survival. • Histatin 3 dose-dependently enhanced both p27{sup Kip1} and HSC70 ubiquitination. • Histatin 3 stimulates cell proliferation via the ubiquitin–proteasome system.

A generation of physicists probing the extremes of gravity can trace its scientific heritage to one man: Kip Thorne of the California Institute of Technology. A recent symposium to mark Thorne's 60th birthday brought together nearly 200 experts on gravity at its strongest and strangest: the domains of black holes, colliding neutron stars, and other exotic deep-space objects. Participants came to honor their mentor, who has led the way in converting Albert Einstein's General Theory of Relativity from a purely theoretical science into an astrophysical and observational one.

The sociology of big science | Public Lecture by Ulrike Felt | 15 July

"The sociology of big science" Public Lecture by Prof. Ulrike Felt Tuesday 15 July 2014 - 7.30 p.m. Globe of Science and Innovation Lecture in English, translated in French. Entrance free. Limited number of seats. Reservation essential: +41 22 767 76 76 or cern.reception@cern.ch What science for what kind of society? Reflecting the development of big science Without any doubt, CERN can be described as being among the most ambitious scientific enterprises ever undertaken. For 60 years, the Member States have not only invested considerable financial means into this institution, but have also supported the creation of a highly visionary research programme. And this has led to a change in the way science is done, as captured by the idea of "big science". Yet this naturally also raises a number of quite fundamental questions: How did the meaning of "doing science" change? What justifies societal engagement with and support for such a cost-intensive long-t...

Although clinical studies have identified that a single nucleotide polymorphism in the p27(kip1) gene is associated with success or failure after vein bypass grafting, the underlying mechanisms for this difference are not well defined. Using a high-throughput approach in a flow-dependent vein graft model, we explored the differences in p27(kip1)-related genes that drive the enhanced hyperplastic response under low-flow conditions. Bilateral rabbit carotid artery interposition grafts with jugular vein were placed with a unilateral distal outflow branch ligation to create differential flow states. Grafts were harvested at 2 hours and at 1, 3, 7, 14, and 28 days after implantation, measured for neointimal area, and assayed for cell proliferation. Whole-vessel messenger RNA was isolated and analyzed using an Affymetrix (Santa Clara, Calif) gene array platform. Ingenuity Pathway Analysis (Ingenuity, Redwood City, Calif) was used to identify the gene networks surrounding p27(kip1). This gene set was then analyzed for temporal expression changes after graft placement and for differential expression in the alternate flow conditions. Outflow branch ligation resulted in an eightfold difference in mean flow rates throughout the 28-day perfusion period (P Flow reduction led to a robust hyperplastic response, resulting in a significant increase in intimal area by 7 days (0.13 ± 0.04 mm(2) vs 0.014 ± 0.006 mm(2); P flow grafts demonstrated a burst of actively dividing intimal cells (36.4 ± 9.4 cells/mm(2) vs 11.5 ± 1.9 cells/mm(2); P = .04). Sixty-five unique genes within the microarray were identified as components of the p27(kip1) network. At a false discovery rate of 0.05, 26 genes demonstrated significant temporal changes, and two dominant patterns of expression were identified. Class comparison analysis identified differential expression of 11 genes at 2 hours and seven genes and 14 days between the high-flow and low-flow grafts (P flow and shear stress result in

Full Text Available It is a norm for people from a multilingual and multicultural country such as Malaysia to speak at least two or more languages. Thus, the Malaysian multilingual situation resulted in speakers having to make decisions about which languages are to be used for different purposes in different domains. In order to explain the phenomenon of language choice, Fishman domain analysis (1964 was adapted into this research. According to Fishman’s domain analysis, language choice and use may depend on the speaker’s experiences situated in different settings, different language repertoires that are available to the speaker, different interlocutors and different topics. Such situations inevitably cause barriers and difficulties to those professionals who work in the education domain. Therefore, the purpose of this research is to explore the language choice and use of Malaysian public university lecturers in the education domain and to investigate whether any significant differences exist between ethnicity and field of study with the English language choice and use of the lecturers. 200 survey questionnaires were distributed to examine the details of the lecturers’ language choice and use. The findings of this research reveal that all of the respondents generally preferred to choose and use English language in both formal and informal education domain. Besides, all of the respondents claimed that they chose and used more than one language. It is also found that ethnicity and field of study of the respondents influence the language choice and use in the education domain. In addition, this research suggested that the language and educational policy makers have been largely successful in raising the role and status of the English language as the medium of instruction in tertiary education while maintaining the Malay language as having an important role in the communicative acts, thus characterizing the lecturers’ language choice and use.

'Rare sugars' are defined as monosaccharides that exist in nature but are only present in limited quantities. The development of mass production method of rare sugars revealed some interesting physiological effects of these on animal cells, but the mechanisms have not been well studied. We examined the effect of D-allose on the proliferation of cancer cells and the underlying molecular mechanism of the action. The HuH-7 hepatocellular carcinoma cells were treated with various monosaccharides for 48 h and D-allose was shown to inhibit cell growth by 40% in a dose-dependent manner. D-allose induced G1 cell cycle arrest but not apoptosis. The microarray analysis revealed that D-allose significantly up-regulated thioredoxin interacting protein (TXNIP) gene expression, which is often suppressed in tumor cells and western blot analysis confirmed its increase at protein level. The overexpression of TXNIP also induced G1 cell cycle arrest. Analysis of cell cycle regulatory genes showed p27kip1, a key regulator of G1/S cell cycle transition, to be increased at the protein but not the transcriptional level. Protein interaction between TXNIP and jab1, and p27kip1 and jab1, was observed, suggesting stabilization of p27kip1 protein by the competitive inhibition of jab1-mediated nuclear export of p27kip1 by TXNIP. In addition, increased interaction and nuclear localization of TXNIP and p27kip1 were apparent after D-allose treatment. Our findings surprisingly suggest that D-allose, a simple monosaccharide, may act as a novel anticancer agent via unique TXNIP induction and p27kip1 protein stabilization.

Dynamics of multiple nuclei in Ashbya gossypii hyphae depend on the control of cytoplasmic microtubules length by Bik1, Kip2, Kip3, and not on a capture/shrinkage mechanism.

Grava, Sandrine; Philippsen, Peter

2010-11-01

Ashbya gossypii has a budding yeast-like genome but grows exclusively as multinucleated hyphae. In contrast to budding yeast where positioning of nuclei at the bud neck is a major function of cytoplasmic microtubules (cMTs), A. gossypii nuclei are constantly in motion and positioning is not an issue. To investigate the role of cMTs in nuclear oscillation and bypassing, we constructed mutants potentially affecting cMT lengths. Hyphae lacking the plus (+)end marker Bik1 or the kinesin Kip2 cannot polymerize long cMTs and lose wild-type nuclear movements. Interestingly, hyphae lacking the kinesin Kip3 display longer cMTs concomitant with increased nuclear oscillation and bypassing. Polymerization and depolymerization rates of cMTs are 3 times higher in A. gossypii than in budding yeast and cMT catastrophes are rare. Growing cMTs slide along the hyphal cortex and exert pulling forces on nuclei. Surprisingly, a capture/shrinkage mechanism seems to be absent in A. gossypii. cMTs reaching a hyphal tip do not shrink, and cMT +ends accumulate in hyphal tips. Thus, differences in cMT dynamics and length control between budding yeast and A. gossypii are key elements in the adaptation of the cMT cytoskeleton to much longer cells and much higher degrees of nuclear mobilities.

Highlights: •CopA3 peptide isolated from the Korean dung beetle has antimicrobial activity. •Our study reported that CopA3 has anticancer and immunosuppressive effects. •We here demonstrated that CopA3 has neurotropic and neuroprotective effects. •CopA3 degrades p27Kip1 protein and this mediates effects of CopA3 on neuronal cells. -- Abstract: We recently demonstrated that the antibacterial peptide, CopA3 (a D-type disulfide dimer peptide, LLCIALRKK), inhibits LPS-induced macrophage activation and also has anticancer activity in leukemia cells. Here, we examined whether CopA3 could affect neuronal cell proliferation. We found that CopA3 time-dependently increased cell proliferation by up to 31 ± 2% in human neuroblastoma SH-SY5Y cells, and up to 29 ± 2% in neural stem cells isolated from neonatal mouse brains. In both cell types, CopA3 also significantly inhibited the apoptosis and viability losses caused by 6-hydroxy dopamine (a Parkinson disease-mimicking agent) and okadaic acid (an Alzheimer’s disease-mimicking agent). Immunoblotting revealed that the p27Kip1 protein (a negative regulator of cell cycle progression) was markedly degraded in CopA3-treated SH-SY5Y cells. Conversely, an adenovirus expressing p27Kip1 significantly inhibited the antiapoptotic effects of CopA3 against 6-hydroxy dopamine- and okadaic acid-induced apoptosis, and decreased the neurotropic effects of CopA3. These results collectively suggest that CopA3-mediated protein degradation of p27Kip1 may be the main mechanism through which CopA3 exerts neuroprotective and neurotropic effects

Attempts at strategic thinking in occupational public health: the Lucas Lecture of 1987

Energy Technology Data Exchange (ETDEWEB)

Millar, J D

1987-05-06

This lecture on strategic thinking in occupational public health stressed that attention must be directed toward the prevention of occupational diseases and injuries through an organized community effort. According to the speaker, such an aim encompasses the various disciplines involved in occupational medicine, safety, and nursing to include such avenues as clinical and social medicine and general public-health practice. A summary was offered of the development of public health and occupational health in the United States, as it grew from the level of state and local responsibility to become a concern of the Federal Government. Occupational medicine also grew at the business sector level with surgical services being established for injured workers at the job site and concerns over toxic exposures growing. The passage of the Occupational Safety and Health Act of 1970 is discussed along with a brief review of new Federal agencies formed by the act. New efforts are being directed at hazard identification and risk assessment, and also at controlling the exposures through preventive or protective measures. Additional efforts are currently being made in the educational field.

S-phase kinase-associated protein 2 (SKP2) gene is a tumor suppressor gene, and is involved in the ubiquitin-mediated degradation of P27kip1. SKP2 and P27kip1 affect the proceeding and prognosis of leukemia through regulating the proliferation, apoptosis and differentiation of leukemia cells. In this study, we explored the mechanism of reversing of HL-60/A drug resistance through SKP2 down-regulation. HL-60/A cells were nucleofected by Amaxa Nucleofector System with SKP2 siRNA. The gene and protein expression levels of Skp2, P27kip1, and multi-drug resistance associated protein (MRP) were determined by reverse transcription-polymerase chain reaction and western blot analysis, respectively. The cell cycle was analyzed by flow cytometry. The 50% inhibitory concentration value was calculated using cytotoxic analysis according to the death rate of these two kinds of cells under different concentrations of chemotherapeutics to compare the sensitivity of the cells. HL-60/A cells showed multi-drug resistance phenotype characteristic by cross-resistance to adriamycin, daunorubicin, and arabinosylcytosine, due to the expression of MRP. We found that the expression of SKP2 was higher in HL-60/A cells than in HL-60 cells, but the expression of P27kip1 was lower. The expression of SKP2 in HL-60/A cells nucleofected by SKP2 siRNA was down-regulated whereas the protein level of P27kip1 was up-regulated. Compared with the MRP expression level in the control group (nucleofected by control siRNA), the mRNA and protein expression levels of MRP in HL-60/A cells nucleofected by SKP2 siRNA were lower, and the latter cells were more sensitive to adriamycin, daunorubicin, and arabinosylcytosine. Down-regulating the SKP2 expression and arresting cells in the G0/G1 phase improve drug sensitivity of leukemia cells with down-regulated MRP expression.

The volume of medical knowledge has increased exponentially and so has the need to improve the efficiency of current teaching practices.With increasing emphasis on interactive and problem based learning, the place of lectures in modern medical education has become a questionable issue. Objectives were to assess the perspective of undergraduate medical students regarding the role and effectiveness of lectures as a mode of instruction as well as the ways and means that can be employed to enhance the effectiveness of lectures. A cross sectional study was carried out among 2nd to final year medical students from five medical colleges including both private and public sector institutions. A total of 347 students participated by completing a structured questionnaire. Data was analyzed using SPSS-17. Sixty seven percent students considered lectures as a useful mode of instruction (47% males and 77% females), whereas 83% of the students reported that clinical sessions were superior to lectures because of small number of students in clinical sessions, active student participation, enhanced clinical orientation, and interaction with patients. About 64% responded that lectures should be replaced by clinical sessions. Majority of the students (92%) reported not being able to concentrate during a lecture beyond 30 minutes, whereas 70% skipped lectures as they were boring. A significantly greater proportion of male respondents, students from clinical years, and those who skipped lectures, considered lectures to be boring, a poor utilization of time and resources, and could not concentrate for the full duration of a lecture compared to females, students from preclinical years, and those who do not skip lectures, respectively. Lecturing techniques need to be improvised. The traditional passive mode of instruction has to be replaced with active learning and inquiry based approach to adequately utilize the time and resources spent on lectures.

During the development of the mammalian cerebral cortex, newborn postmitotic projection neurons are born from local neural stem cells and must undergo radial migration so as to position themselves appropriately to form functional neural circuits. The zinc finger transcriptional repressor Rp58 (also known as Znf238 or Zbtb18) is critical for coordinating corticogenesis, but its underlying molecular mechanism remains to be better characterised. Here, we demonstrate that the co-expression of Rp58 and the cyclin dependent kinase inhibitor (CDKI) p27 kip1 is important for E14.5-born cortical neurons to coordinate cell cycle exit and initiate their radial migration. Notably, we find that the impaired radial positioning of Rp58-deficient cortical neurons within the embryonic (E17.5) mouse cortex, as well as their multipolar to bipolar transition from the intermediate zone to the cortical plate can be restored by forced expression of p27 kip1 in concert with suppression of Rnd2, a downstream target gene of Rp58. Furthermore, the restorative effects of p27 kip1 and Rnd2 abrogation are reminiscent of suppressing RhoA signalling in Rp58-deficient cells. Our findings demonstrate functional interplay between a transcriptional regulator and a CDKI to mediate neuroprogenitor cell cycle exit, as well as to promote radial migration through a molecular mechanism consistent with suppression of RhoA signalling.

Endometriosis is a gynecological benign chronic disease defined as the growth of endometrial glands and stroma in extra-uterine sites, most commonly implanted over visceral and peritoneal surfaces within the female pelvis causing inflammatory lesions. It affects around 10% of the female population and is often accompanied by chronic pelvic pain, adhesion formation and infertility. Therefore, endometriosis could be considered a "social disease", since it affects the quality of life, reproductivity and also has a socio-economic impact. The expression of cell cycle and inflammatory proteins is modified in the endometriotic tissues. Immunostaining of glandular and stromal cells in endometrial biopsies obtained from patients with endometriosis compared with those of healthy control demonstrated that endometriotic tissues have lower levels of p27 kip1 protein. Endometriosis endometrial cells cultures have also lower levels of p27 kip1 compared to health endometrial cells cultures and restore the cell cycle balance when transduced with an adenoviral vector carring the p27 kip1 coding gene (Adp27EGFP). The low levels of p27 kip1 are related to the S phase in the cell cycle, whereas higher levels lead to a G1 cell cycle arrest. The inflammatory cytokine IL-1β was recently identified as another key protein in the endometriosis proliferation. This cytokine has elevated levels during the proliferative and secretory phases of the menstrual cycle. In endometriosis endometrial cells cultures the IL-1β stimulates the production of IL-6 and IL-8, increasing the cell proliferation and reducing the apoptosis and Bax expression in these cells. According to these remarks, this work aims to evaluate the inflammatory effects in vitro, but more next to what happens in a woman's body, associating endometrial cells with stem cells, thus mimicking the endometrial microenvironment, with gene therapy using Adp27, notoriously known as controller cell cycle, apoptosis and potent modulator of

Lecturer on tour!

Readers may recall the interview with Professor Peter Kalmus which appeared in the July issue of Physics Education and which indicated his latest role of lecturer for the 1998-9 Institute of Physics Schools and Colleges Lecture series. This year's lecture is entitled `Particles and the universe' and the tour was due to begin in St Andrews, Scotland, late in September. Professor Kalmus will be looking at various aspects of particle physics, quantum physics and relativity, and discussing how they reveal the secrets of the beginning of our universe. His own experience of working at CERN, the European centre for particle physics in Switzerland, as well as at other international research facilities will provide a unique insight into activity in one of the most exciting areas of physics. The talks are aimed at the 16-19 age group but members of the public are also welcome to attend. They will act as an opportunity to gain a sneak preview of the dynamic new topics that will soon feature in the A-level syllabus arising from the Institute's 16-19 project. Further details of attendance are available from the local organizers, a list of whom may be obtained from Catherine Wilson in the Education Department at the Institute of Physics, 76 Portland Place, London W1N 3DH (tel: 0171 470 4800, fax: 0171 470 4848).

Gastric cancer is the second most common cause of global cancer-related mortality. Although dedifferentiation predicts poor prognosis in gastric cancer, the molecular mechanism underlying dedifferentiation, which could provide fundamental insights into tumor development and progression, has yet to be elucidated. Furthermore, the molecular mechanism underlying the effects of hexamethylene bisacetamide (HMBA), a recently discovered differentiation inducer, requires investigation and there are no reported studies concerning the effect of HMBA on gastric cancer. Based on the results of FACS analysis, the levels of proteins involved in the cell cycle or apoptosis were determined using western blotting after single treatments and sequential combinations of HMBA and LiCl. GSK-3β and proton pump were investigated by western blotting after up-regulating Akt expression by Ad-Akt infection. To investigate the effects of HMBA on protein localization and the activities of GSK-3β, CDK2 and CDK4, kinase assays, immunoprecipitation and western blotting were performed. In addition, northern blotting and RNase protection assays were carried out to determine the functional concentration of HMBA. HMBA increased p27Kip1 expression and induced cell cycle arrest associated with gastric epithelial cell differentiation. In addition, treating gastric-derived cells with HMBA induced G0/G1 arrest and up-regulation of the proton pump, a marker of gastric cancer differentiation. Moreover, treatment with HMBA increased the expression and activity of GSK-3β in the nucleus but not the cytosol. HMBA decreased CDK2 activity and induced p27Kip1 expression, which could be rescued by inhibition of GSK-3β. Furthermore, HMBA increased p27Kip1 binding to CDK2, and this was abolished by GSK-3β inhibition. The results presented herein suggest that GSK-3β functions by regulating p27Kip1 assembly with CDK2, thereby playing a critical role in G0/G1 arrest associated with HMBA-induced gastric epithelial

MicroRNAs are short regulatory RNAs that negatively modulate protein expression at a post-transcriptional level and are deeply involved in the pathogenesis of several types of cancers. Here we show that miR-221 and miR-222, encoded in tandem on chromosome X, are overexpressed in the PC3 cellular model of aggressive prostate carcinoma, as compared with LNCaP and 22Rv1 cell line models of slowly growing carcinomas. In all cell lines tested, we show an inverse relationship between the expression of miR-221 and miR-222 and the cell cycle inhibitor p27(Kip1). We recognize two target sites for the microRNAs in the 3' untranslated region of p27 mRNA, and we show that miR-221/222 ectopic overexpression directly results in p27 down-regulation in LNCaP cells. In those cells, we demonstrate that the ectopic overexpression of miR-221/222 strongly affects their growth potential by inducing a G(1) to S shift in the cell cycle and is sufficient to induce a powerful enhancement of their colony-forming potential in soft agar. Consistently, miR-221 and miR-222 knock-down through antisense LNA oligonucleotides increases p27(Kip1) in PC3 cells and strongly reduces their clonogenicity in vitro. Our results suggest that miR-221/222 can be regarded as a new family of oncogenes, directly targeting the tumor suppressor p27(Kip1), and that their overexpression might be one of the factors contributing to the oncogenesis and progression of prostate carcinoma through p27(Kip1) down-regulation.

Bos, Henk J M

1993-01-01

"[These lectures] are about themes of the history of mathematics which, for various reasons, are dear to me. The early differential and integral calculus, the work of Christiaan Huygens, and the concept of construction in seventeenth- and eighteenth-century mathematics are the three themes around which much of my research has concentrated and which continue to fascinate me by the insights they offer in the development of that special human activity called mathematics." -from the Introduction This volume contains eleven lectures ranging over a variety of topics in the history of mathematics. The lectures, presented between 1970 and 1987, were delivered in a variety of venues and appeared only in less accessible publications. Those who teach mathematics, as well as mathematics historians, will appreciate this insightful, wide-ranging book.

In Vivo Interplay between p27Kip1, GATA3, ATOH1, and POU4F3 Converts Non-sensory Cells to Hair Cells in Adult Mice

Directory of Open Access Journals (Sweden)

Bradley J. Walters

2017-04-01

Full Text Available Summary: Hearing loss is widespread and persistent because mature mammalian auditory hair cells (HCs are nonregenerative. In mice, the ability to regenerate HCs from surrounding supporting cells (SCs declines abruptly after postnatal maturation. We find that combining p27Kip1 deletion with ectopic ATOH1 expression surmounts this age-related decline, leading to conversion of SCs to HCs in mature mouse cochleae and after noise damage. p27Kip1 deletion, independent of canonical effects on Rb-family proteins, upregulated GATA3, a co-factor for ATOH1 that is lost from SCs with age. Co-activation of GATA3 or POU4F3 and ATOH1 promoted conversion of SCs to HCs in adult mice. Activation of POU4F3 alone also converted mature SCs to HCs in vivo. These data illuminate a genetic pathway that initiates auditory HC regeneration and suggest p27Kip1, GATA3, and POU4F3 as additional therapeutic targets for ATOH1-mediated HC regeneration. : Auditory hair cells are nonregenerative, resulting in persistent hearing loss upon damage. Walters et al. find that manipulating two genes, p27Kip1 and Atoh1, induces the conversion of nonsensory cells to hair cells in adult mice. This effect is mediated by GATA3 and POU4F3, where POU4F3 alone was found to convert nonsensory cells.

Varao-Sousa, Trish L; Kingstone, Alan

2015-01-01

The present study investigated what impact the presentation style of a classroom lecture has on memory, mind wandering, and the subjective factors of interest and motivation. We examined if having a professor lecturing live versus on video alters the learning experience of the students in the classroom. During the lectures, students were asked to report mind wandering and later complete a memory test. The lecture format was manipulated such that all the students received two lectures, one live and one a pre-recorded video. Results indicate that lecture format affected memory performance but not mind wandering, with enhanced memory in the live lectures. Additionally, students reported greater interest and motivation in the live lectures. Given that a single change to the classroom environment, professor presence, impacted memory performance, as well as motivation and interest, the present results have several key implications for technology-based integrations into higher education classrooms.

In light of educators' concerns that lecture attendance in medical school has declined, the authors sought to assess students' perceptions, evaluations, and motivations concerning live lectures compared with accelerated, video-recorded lectures viewed online. The authors performed a cross-sectional survey study of all first- and second-year students at Harvard Medical School. Respondents answered questions regarding their lecture attendance; use of class and personal time; use of accelerated, video-recorded lectures; and reasons for viewing video-recorded and live lectures. Other questions asked students to compare how well live and video-recorded lectures satisfied learning goals. Of the 353 students who received questionnaires, 204 (58%) returned responses. Collectively, students indicated watching 57.2% of lectures live, 29.4% recorded, and 3.8% using both methods. All students have watched recorded lectures, and most (88.5%) have used video-accelerating technologies. When using accelerated, video-recorded lecture as opposed to attending lecture, students felt they were more likely to increase their speed of knowledge acquisition (79.3% of students), look up additional information (67.7%), stay focused (64.8%), and learn more (63.7%). Live attendance remains the predominant method for viewing lectures. However, students find accelerated, video-recorded lectures equally or more valuable. Although educators may be uncomfortable with the fundamental change in the learning process represented by video-recorded lecture use, students' responses indicate that their decisions to attend lectures or view recorded lectures are motivated primarily by a desire to satisfy their professional goals. A challenge remains for educators to incorporate technologies students find useful while creating an interactive learning culture.

Full Text Available Competence is one of the important parts of brand study, while brand it is a part of the marketing that has an important position by selling product and services. So brand itself not only for the company, it can also manage individual brands, public figures, and lecturer. This research aimed for determining the use of blogs as a medium to support the competence of lecturers from the aspect trustworthiness, commitment, ability to develop themselves practicing a profession, and a limiting factor in building the competence of lecturers. This research uses a qualitative approach with a single case study through observation, interviews, focus group discussions, and literature. The study found that lecturer use blogs to share lectures, ideas about contemporary events, and upload Islamic articles. Lecturer assessed reliably, because the lecturer writing on a blog is the result of his work, and a lot of consultation requests from various circles. The lecturer is committed to making a change for the better in every way when communicating via blog to maintain conformity with the words of his behavior, and lecturer has the ability to develop themselves in their profession as a lecturer, that gives him the strength to continue working.

Authentic Astronomical Discovery in Planetariums: Data-Driven Immersive Lectures

Wyatt, Ryan Jason

2018-01-01

Planetariums are akin to “branch offices” for astronomy in major cities and other locations around the globe. With immersive, fulldome video technology, modern digital planetariums offer the opportunity to integrate authentic astronomical data into both pre-recorded shows and live lectures. At the California Academy of Sciences Morrison Planetarium, we host the monthly Benjamin Dean Astronomy Lecture Series, which features researchers describing their cutting-edge work to well-informed lay audiences. The Academy’s visualization studio and engineering teams work with researchers to visualize their data in both pre-rendered and real-time formats, and these visualizations are integrated into a variety of programs—including lectures! The assets are then made available to any other planetariums with similar software to support their programming. A lecturer can thus give the same immersive presentation to audiences in a variety of planetariums. The Academy has also collaborated with Chicago’s Adler Planetarium to bring Kavli Fulldome Lecture Series to San Francisco, and the two theaters have also linked together in live “domecasts” to share real-time content with audiences in both cities. These lecture series and other, similar projects suggest a bright future for astronomers to bring their research to the public in an immersive and visually compelling format.

The Web-Lecture - a viable alternative to the traditional lecture format?

Science.gov (United States)

Meibom, S.

2004-12-01

Educational research shows that students learn best in an environment with emphasis on teamwork, problem-solving, and hands-on experience. Still professors spend the majority of their time with students in the traditional lecture-hall setting where the combination of large classes and limited time prevents sufficient student-teacher interaction to foster an active learning environment. Can modern computer technology be used to provide "lecture-type" information to students via the World Wide Web? If so, will that help professors make better and/or different use of their scheduled time with the students? Answering these questions was the main motivation for the Extra-Solar Planet Project. The Extra-Solar Planet Project was designed to test the effectiveness of a lecture available to the student on the World Wide Web (Web-Lecture) and to engage the students in an active learning environment were their use the information presented in the Web-Lecture. The topic of the Web-Lecture was detection of extra-solar planets and the project was implemented into an introductory astronomy course at University of Wisconsin Madison in the spring of 2004. The Web-Lecture was designed to give an interactive presentation of synchronized video, audio and lecture notes. It was created using the eTEACH software developed at the University of Wisconsin Madison School of Engineering. In my talk, I will describe the project, show excerpts of the Web-Lecture, and present assessments of student learning and results of student evaluations of the web-lecture format.

Vocal intensity in lecturers: Results of measurements conducted during lecture sessions

Witold Mikulski

2013-12-01

Full Text Available Background: Occupational voice users (inter alia: lecturers speak with different levels of vocal intensity. Speakers adjust this intensity knowingly (e.g. to underline the importance of fragments of the speech or unknowingly. The unknown adjustment of voice intensity occurs e.g. in the presence of high acoustic background noise (so-called Lombard effect, but it also results from many other factors: hearing loss, construction of the vocal tract, habits and others. The aim of the article is to confirm the thesis that in similar conditions of acoustic properties of the room different lecturers speak with different levels of vocal intensity. Materials and Methods: The study was conducted in a group of 10 lecturers in the same conference room. A-weighted sound pressure level determined at 1 m from the lecturer's mouth was adopted as a parameter defining the intensity of the lecturer's voice. The levels of all lecturers' voice intensity were compared and evaluated according to the criteria defined in EN ISO 9921. Results: Nine in ten lecturers were speaking with normal voice intensity (60-65 dB and only one full-time university lecturer was speaking with raised voice (66-71 dB. Conclusions: It was found that in the room of the same acoustic conditions the lecturers spoke with different intensities of voice. Some lecturers occasionally, and one all the time spoke with the voice intensity specified by PN-EN ISO 9921 as a raised voice. The results of the preliminary study warrant further studies in a larger group of teachers. Med Pr 2013;64(6:797–804

In vitro differentiation of HT-29 M6 mucus-secreting colon cancer cells involves a trychostatin A and p27(KIP1)-inducible transcriptional program of gene expression.

Mayo, Clara; Lloreta, Josep; Real, Francisco X; Mayol, Xavier

Tumor cell dedifferentiation-such as the loss of cell-to-cell adhesion in epithelial tumors-is associated with tumor progression. To better understand the mechanisms that maintain carcinoma cells in a differentiated state, we have dissected in vitro differentiation pathways in the mucus-secretor HT-29 M6 colon cancer cell line, which spontaneously differentiates in postconfluent cultures. By lowering the extracellular calcium concentration to levels that prevent intercellular adhesion and epithelial polarization, our results reveal that differentiation is calcium-dependent and involves: (i) a process of cell cycle exit to G(0) and (ii) the induction of a transcriptional program of differentiation gene expression (i.e., mucins MUC1 and MUC5AC, and the apical membrane peptidase DPPIV). In calcium-deprived, non-differentiated postconfluent cultures, differentiation gene promoters are repressed by a trichostatin A (TSA)-sensitive mechanism, indicating that loss of gene expression by dedifferentiation is driven by histone deacetylases (HDAC). Since TSA treatment or extracellular calcium restoration allow gene promoter activation to similar levels, we suggest that induction of differentiation is one mechanism of HDAC inhibitor antitumor action. Moreover, transcriptional de-repression can also be induced in non-differentiating culture conditions by overexpressing the cyclin-dependent kinase inhibitor p27(KIP1), which is normally induced during spontaneous differentiation. Since p27(KIP1) downregulation in colon cancer is associated with poor prognosis independently of tumor cell division rates, we propose that p27 (KIP1) may prevent tumor progression by, at least in part, enhancing the expression of some differentiation genes. Therefore, the HT-29 M6 model allows the identification of some basic mechanisms of cancer cell differentiation control, so far revealing HDAC and p27(KIP1) as key regulatory factors of differentiation gene expression.

The inhibition of activated hepatic stellate cells proliferation by arctigenin through G0/G1 phase cell cycle arrest: persistent p27(Kip1) induction by interfering with PI3K/Akt/FOXO3a signaling pathway.

2015-01-15

Proliferation of hepatic stellate cells (HSCs) is vital for the development of fibrosis during liver injury. In this study, we describe that arctigenin (ATG), a major bioactive component of Fructus Arctii, exhibited selective cytotoxic activity via inhibiting platelet-derived growth factor-BB (PDGF-BB)-activated HSCs proliferation and arrested cell cycle at G0/G1 phase, which could not be observed in normal human hepatocytes in vitro. The cyclin-dependent kinase (CDK) 4/6 activities could be strongly inhibited by ATG through down-regulation of cyclin D1 and CDK4/6 expression in early G1 phase arrest. In the ATG-treated HSCs, the expression level of p27(Kip1) and the formation of CDK2-p27(Kip1) complex were also increased. p27(Kip1) silencing significantly attenuated the effect of ATG, including cell cycle arrest and suppression of proliferation in activated HSCs. We also found that ATG suppressed PDGF-BB-induced phosphorylation of Akt and its downstream transcription factor Forkhead box O 3a (FOXO3a), decreased binding of FOXO3a to 14-3-3 protein, and stimulated nuclear translocation of FOXO3a in activated HSCs. Furthermore, knockdown of FOXO3a expression by FOXO3a siRNA attenuated ATG-induced up-regulation of p27(Kip1) in activated HSCs. All the above findings suggested that ATG could increase the levels of p27(Kip1) protein through inhibition of Akt and improvement of FOXO3a activity, in turn inhibited the CDK2 kinase activity, and eventually caused an overall inhibition of HSCs proliferation.

We have shown that dietary fish oil is protective against experimentally induced colon cancer, and the protective effect is enhanced by coadministration of pectin. However, the underlying mechanisms have not been fully elucidated. We hypothesized that fish oil with butyrate, a pectin fermentation product, protects against colon cancer initiation by decreasing cell proliferation and increasing differentiation and apoptosis through a p27(Kip1)-mediated mechanism. Rats were provided diets of corn or fish oil, with/without butyrate, and terminated 12, 24, or 48 hours after azoxymethane (AOM) injection. Proliferation (Ki-67), differentiation (Dolichos Biflorus Agglutinin), apoptosis (TUNEL), and p27(Kip1) (cell-cycle mediator) were measured in the same cell within crypts in order to examine the coordination of cell cycle as a function of diet. DNA damage (N(7)-methylguanine) was determined by quantitative IHC analysis. Dietary fish oil decreased DNA damage by 19% (P = 0.001) and proliferation by 50% (P = 0.003) and increased differentiation by 56% (P = 0.039) compared with corn oil. When combined with butyrate, fish oil enhanced apoptosis 24 hours after AOM injection compared with a corn oil/butyrate diet (P = 0.039). There was an inverse relationship between crypt height and apoptosis in the fish oil/butyrate group (r = -0.53, P = 0.040). The corn oil/butyrate group showed a positive correlation between p27(Kip1) expression and proliferation (r = 0.61, P = 0.035). These results indicate the in vivo effect of butyrate on apoptosis and proliferation is dependent on dietary lipid source. These results demonstrate the presence of an early coordinated colonocyte response by which fish oil and butyrate protects against colon tumorigenesis. ©2015 American Association for Cancer Research.

In his lecture, the author discusses the question as to whether our technical standards come up to the requirements of our legal system. It is true that acceptance of our technical standards is voluntary but, as in the case of standards issued by the Government, standardization will only prove useful when accepted by the majority of the citizens. This becomes evident in cases where the health and quality of life of the citizens has to be defended against the impacts of technical progress. Here, the state has to fulfil a protective function for the benefit of its citizens. Hence the 'standardization contract' has been agreed upon in order to guarantee compliance of technical standards and requirements with the interests of public life and health. (HSCH) [de

Full Text Available In the early 20th century, some American ministers were eager participants in the Chautauqua and Lyceum lecture circuits that flourished across the Midwest and beyond. Ministers expressed their vocation in the public arena, and the Redpath Chautauqua collection shows how part of this public life was conducted. In their role as lecturers in multiple educational and civic venues, ministers functioned as experts on the Bible, as well as supporting American ideals that were loosely connected to Protestant Christianity. The essay explores how a substantial archival collection reveals a particular public role ministers played in a popular culture venue in early 20th century America.

Bexarotene (Targretin ® ) is currently the only FDA approved retinoid X receptor (RXR) -selective agonist for the treatment of cutaneous T-cell lymphomas (CTCLs). The main side effects of bexarotene are hypothyroidism and elevation of serum triglycerides (TGs). The novel RXR ligand, 9-cis UAB30 (UAB30) does not elevate serum TGs or induce hypothyroidism in normal subjects. To assess preclinical efficacy and mechanism of action of UAB30 in the treatment of CTCLs and compare its action with bexarotene. With patient-derived CTCL cell lines, we evaluated UAB30 function in regulating growth, apoptosis, cell cycle check points, and cell cycle-related markers. Compared to bexarotene, UAB30 had lower half maximal inhibitory concentration (IC 50 ) values and was more effective in inhibiting the G1 cell cycle checkpoint. Both rexinoids increased the stability of the cell cycle inhibitor, p27kip1 protein, in part, through targeting components involved in the ubiquitination-proteasome system: 1) decreasing SKP2, a F-box protein that binds and targets p27kip1 for degradation by 26S proteasome and 2) suppressing 20S proteasome activity (cell line-dependent) through downregulation of PSMA7, a component of the 20S proteolytic complex in 26S proteasome. UAB30 and bexarotene induce both early cell apoptosis and suppress cell proliferation. Inhibition of the G1 to S cell cycle transition by rexinoids is mediated, in part, through downregulation of SKP2 and/or 20S proteasome activity, leading to increased p27kip1 protein stability. Because UAB30 has minimal effect in elevating serum TGs and inducing hypothyroidism, it is potentially a better alternative to bexarotene for the treatment of CTCLs.

Kilowatt Isotope Power System. Phase I. System test report. 78-KIPS-33

International Nuclear Information System (INIS)

1978-01-01

The KIPS Ground Demonstration System (GDS) was designed to simulate, as closely as possible, a Flight System Conceptual Design (FSCD). No radiator was incorporated and electric heat sources were used in place of isotope heat sources. To minimize air in-leakage and to simulate heat losses associated with space operation, the system was operated in a vacuum chamber. Initial testing was performed on the development system which did not incorporate a high performance turbine or non-condensing configuration of the cold liquid passages in certain regenerator vapor regions. After testing of the development system and retrofit to the GDS configuration, which included improvements in the above two items, the GDS was installed in the test chamber. Testing to date showed the GDS configuration has demonstrated a system efficiency of greater than 15%. Satisfactory heat balances have been calculated on most system components, permitting evaluation of component performance. Certain performance deficiencies currently exist which prevented the 18% efficiency goal being attained. These can be corrected with further development

Listen and Watch: The Practice of Lecturing and the Epistemological Status of Sex Education Films in Germany.

Science.gov (United States)

Laukötter, Anja

2015-01-01

This article takes as its starting point Frauennot-Frauenglück (Women's Misery--Women's Happiness), a film representative of health education films on sex hygiene in Weimar Germany. This paper opens by situating the film in the landscape of German health education films from World War I to the Weimar era. I document the evolution of interest in sexual health education films in the early decades of the twentieth century and show how their narratives changed as a result of the increasing popularity of feature films in the Weimar period. The article then focuses on the lectures which accompanied health education films. I argue that an analysis of these under-investigated lectures can raise new stimulating epistemological questions on the historical status of health education films, as these lectures changed the filmic dispositive. I show how this common practice served as a technique of rhetorical reworking in efforts to adjust or orient the visuality of what was shown to the public. Drawing on two very different lectures which accompanied Frauennot-Frauenglück, the article identifies two approaches to lecturing. While one consisted in enabling controversial films to be screened to the public, the other (socialist) approach transforms initial censorial intentions, allowing the speaker stress his personal or new positions.

Herbal composition of Cinnamomum cassia, Pinus densiflora, Curcuma longa and Glycyrrhiza glabra prevents atherosclerosis by upregulating p27 (Kip1) expression.

Kiom-18 is a novel composition of Cinnamomum cassia, Pinus densiflora, Curcuma longa and Glycyrrhiza glabra. Curcuma longa and Glycyrrhiza glabra, which are traditional medicines in Asia, have been reported to demonstrate preventive effects against atherosclerosis; however, they have not yet been developed into functional atherosclerosis treatments. We therefore studied the anti-atherosclerotic effects and possible molecular mechanisms of Kiom-18 using vascular smooth muscle cells (VSMCs). To assess the anti-proliferative effect of Kiom-18 in vitro, we performed thymidine incorporation, cell cycle progression, immunoblotting and immunofluorescence assays in VSMCs stimulated by platelet derived-growth factor (PDGF)-BB. In addition, we used LDLr knockout mice to identify the effects of Kiom-18 as a preliminary result in an atherosclerosis animal model. Kiom-18 inhibited platelet-derived growth factor (PDGF)-BB-stimulated-VSMC proliferation and DNA synthesis. Additionally, Kiom-18 arrested the cell cycle transition of G0/G1 stimulated by PDGF-BB and its cell cycle-related proteins. Correspondingly, the level of p27(kip1) expression was upregulated in the presence of the Kiom-18 extract. Moreover, in an atherosclerosis animal model of LDLr knockout mice, Kiom-18 extract showed a preventive effect for the formation of atherosclerotic plaque and suppressed body weight, fat weight, food treatment efficiency, neutrophil count, and triglyceride level. These results indicate that Kiom-18 exerts anti-atherosclerotic effects by inhibiting VSMC proliferation via G0/G1 arrest, which upregulates p27(Kip1) expression.

The study of Einstein's theory of general relativity experienced a renaissance beginning in the early 1960s. Prior to this resurgence of interest, general relativity was isolated from mainstream physics-admired for its elegance, perhaps, but only from a distance. The generation of students who risked their careers by entering this neglected field has now reached the age of festschrifts. In June of 2000, Caltech hosted ;Kipfest,; a conference in honor of Kip Thorne's 60th birthday. Thorne started graduate school at Princeton in 1962 and began research in general relativity under John Wheeler's guidance in the heady early days of the renaissance. Since then, he has played a prominent role in general relativity: as co-author of the influential textbook Gravitation, as a leader in research regarding astrophysical applications of Einstein's theory, and as a co-founder and chief advocate for the Laser Interferometer Gravitational Wave Observatory (LIGO), to mention a few aspects of his far-reaching work. ;Kipfest; included 14 speakers discussing fields to which Thorne has contributed. But the conference also reflected Thorne's long-standing commitment to communicating science to a general audience: Igor Novikov, Stephen Hawking, Timothy Ferris, and Alan Lightman gave popular talks at ;Kipfest,; with Thorne himself tricked into delivering a fifth. The Future of Spacetime gathers adaptations of these five lectures, along with a lengthy introductory essay by Richard Price.

Explicit constructivism: a missing link in ineffective lectures?

Science.gov (United States)

Prakash, E S

2010-06-01

This study tested the possibility that interactive lectures explicitly based on activating learners' prior knowledge and driven by a series of logical questions might enhance the effectiveness of lectures. A class of 54 students doing the respiratory system course in the second year of the Bachelor of Medicine and Bachelor of Surgery program in my university was randomized to two groups to receive one of two types of lectures, "typical" lectures (n = 28, 18 women and 10 men) or "constructivist" lectures (n = 26, 19 women and 7 men), on the same topic: the regulation of respiration. Student pretest scores in the two groups were comparable (P > 0.1). Students that received the constructivist lectures did much better in the posttest conducted immediately after the lectures (6.8 +/- 3.4 for constructivist lectures vs. 4.2 +/- 2.3 for typical lectures, means +/- SD, P = 0.004). Although both types of lectures were well received, students that received the constructivist lectures appeared to have been more satisfied with their learning experience. However, on a posttest conducted 4 mo later, scores obtained by students in the two groups were not any different (6.9 +/- 3 for constructivist lectures vs. 6.9 +/- 3.7 for typical lectures, P = 0.94). This study adds to the increasing body of evidence that there is a case for the use of interactive lectures that make the construction of knowledge and understanding explicit, easy, and enjoyable to learners.

Flipped classroom or an active lecture?

Science.gov (United States)

Pickering, James D; Roberts, David J H

2018-01-01

Recent changes in anatomy education have seen the introduction of flipped classrooms as a replacement to the traditional didactic lecture. This approach utilizes the increasing availability of digital technology to create learning resources that can be accessed prior to attending class, with face-to-face sessions then becoming more student-centered via discussion, collaborative learning, and problem-solving activities. Although this approach may appear intuitive, this viewpoint commentary presents a counter opinion and highlights a simple alternative that utilizes evidence-based active learning approaches as part of the traditional lecture. The active lecture takes the traditional lecture, and (1) ensures the lecture content is relevant and has clear objectives, (2) contains lecture material that is designed according to the latest evidence-base, (3) complements it with additional supplementary material, (4) creates space to check prior understanding and knowledge levels, and (5) utilizes suitable technology to facilitate continual engagement and interaction.

Electronic voting to encourage interactive lectures: a randomised trial

Science.gov (United States)

2007-01-01

Background Electronic Voting Systems have been used for education in a variety of disciplines. Outcomes from these studies have been mixed. Because results from these studies have been mixed, we examined whether an EVS system could enhance a lecture's effect on educational outcomes. Methods A cohort of 127 Year 5 medical students at the University of Adelaide was stratified by gender, residency status and academic record then randomised into 2 groups of 64 and 63 students. Each group received consecutive 40-minute lectures on two clinical topics. One group received the EVS for both topics. The other group received traditional teaching only. Evaluation was undertaken with two, 15-question multiple-choice questionnaires (MCQ) assessing knowledge and problem solving and undertaken as a written paper immediately before and after the lectures and repeated online 8–12 weeks later. Standardised institutional student questionnaires were completed for each lecture and independent observers assessed student behaviour during the lectures. Lecturer's opinions were assessed by a questionnaire developed for this study. Results Two-thirds of students randomised to EVS and 59% of students randomised to traditional lectures attended. One-half of the students in the EVS group and 41% in the traditional group completed all questionnaires. There was no difference in MCQ scores between EVS and traditional lectures (p = 0.785). The cervical cancer lectures showed higher student ranking in favour of EVS in all parameters. The breast cancer lectures showed higher ranking in favour of traditional lectures in 5 of 7 parameters (p lecturer-students interactions were increased in the EVS lecture for one lecturer and reduced for the other. Both lecturers felt that the EVS lectures were difficult to prepare, that they were able to keep to time in the traditional lectures, that the educational value of both lecture styles was similar, and that they were neutral-to-slightly favourably disposed

2015-08-01

Full Text Available Background: Lombard’s effect increases the level of vocal intensity in the environment, in which noise occurs. This article presents the results of the author’s own study of vocal intensity level and A-weighted sound pressure level of background noise during normal lectures. The aim of the study was to define whether above-mentioned parameters depend on acoustic properties of rooms (classrooms or lecture rooms and to define how many lectors speak with raised voice. Material and Methods: The study was performed in a group of 50 teachers and lecturers in 10 classrooms with cubature of 160–430 m3 and reverberation time of 0.37–1.3 s (group A consisted of 3 rooms which fulfilled, group B consisted of 3 rooms which almost fulfilled and group C consisted of 4 rooms which did not fulfill criteria based on reverberation time (maximum permissible value is 0.6–0.8 s according to PN-B-02151-4:2015. Criteria of raising voice were based on vocal intensity level (maximum value: 65 dB according to EN ISO 9921:2003. The values of above-mentioned parameters were determined from modes of A-weighted sound pressure level distributions during lectures. Results: Great differentiation of vocal intensity level between lectors was found. In classrooms of group A lectors were not using raised voice, in group B – 21%, and in group C – 60% of lectors were using raised voice. Conclusions: It was observed that acoustic properties of classrooms (defined by reverberation time exert their effect on lecturer’s vocal intensity level (i.e., raising voice, which may contribute to the increased risk of vocal tract illnesses. The occurrence of Lombard’s effect in groups of teachers and lecturers, conducting lectures in rooms, was evidenced. Med Pr 2015;66(4:487–496

We will mention simulation and concentrate on track finding and reconstruction, reviewing different algorithms prototyped for the LHC experiments. We will ...

Do not Lose Your Students in Large Lectures: A Five-Step Paper-Based Model to Foster Students’ Participation

Full Text Available Like most of the pharmacy colleges in developing countries with high population growth, public pharmacy colleges in Egypt are experiencing a significant increase in students’ enrollment annually due to the large youth population, accompanied with the keenness of students to join pharmacy colleges as a step to a better future career. In this context, large lectures represent a popular approach for teaching the students as economic and logistic constraints prevent splitting them into smaller groups. Nevertheless, the impact of large lectures in relation to student learning has been widely questioned due to their educational limitations, which are related to the passive role the students maintain in lectures. Despite the reported feebleness underlying large lectures and lecturing in general, large lectures will likely continue to be taught in the same format in these countries. Accordingly, to soften the negative impacts of large lectures, this article describes a simple and feasible 5-step paper-based model to transform lectures from a passive information delivery space into an active learning environment. This model mainly suits educational establishments with financial constraints, nevertheless, it can be applied in lectures presented in any educational environment to improve active participation of students. The components and the expected advantages of employing the 5-step paper-based model in large lectures as well as its limitations and ways to overcome them are presented briefly. The impact of applying this model on students’ engagement and learning is currently being investigated.

Are radiography lecturers, leaders?

International Nuclear Information System (INIS)

Hendry, Julie Anne

2013-01-01

This review article aims to explore the concept of radiography lecturers acting as leaders to their student followers. Through a brief review of the literature, a definition of leadership is suggested and some leadership theories explored. The path-goal theory, leader–member exchange theory and the contemporary theory of transformational leadership are examined more closely. Links between lecturer-leader behaviour and student motivation and learning are tentatively suggested with transformational leadership appearing to offer the optimal leadership style for lecturers to adopt. The paucity of literature relating directly to radiography is acknowledged and areas for further research are suggested. The article concludes with some of the author's practical ideas for incorporating transformational leadership styles and behaviours into radiography education today

Albert Einstein memorial lectures

CERN Document Server

Mechoulam, Raphael; The Israel Academy for Sciences and Humanities

2012-01-01

This volume consists of a selection of the Albert Einstein Memorial Lectures presented annually at the Israel Academy of Sciences and Humanities. Delivered by eminent scientists and scholars, including Nobel laureates, they cover a broad spectrum of subjects in physics, chemistry, life science, mathematics, historiography and social issues. This distinguished memorial lecture series was inaugurated by the Israel Academy of Sciences and Humanities following an international symposium held in Jerusalem in March 1979 to commemorate the centenary of Albert Einstein's birth. Considering that Einstein's interests, activities and influence were not restricted to theoretical physics but spanned broad fields affecting society and the welfare of humankind, it was felt that these memorial lectures should be addressed to scientists, scholars and erudite laypersons rather than to physicists alone.

As a result of the research, it was necessary to answer the following important questions: What are the objectives of the lecture and the role of the lecturer? Which lectures are more preferable: traditional or interactive? What do lecturers expect from the lecture, do they consider it an advantage or an unnecessary educational activity?The materials were developed for the survey (questionnaire to conduct the research and analyze the results obtained. The students were surveyed before training and after completion of the semester. The study involved 200 students of all areas of Mechanics and Technology Faculty of Novosibirsk State Technical University. Statistical analysis was used for the analysis of the results.As a result, the experiment revealed nonconformity of opinions of students about the purpose of the lecture and the role of a lecturer before the training and after the end of the semester. Lectures, according to students, should help to implement all kinds of practical and independent assignments.Educational standards imply a reduction in the hours of classroom training and an increase in independent work, and the majority of students are not ready (do not want to to study the materials on the topics of discipline completely independently or partially.It revealed a contradiction in opinion, what form of organization of the lecture classes is more interesting to students, which can increase the motivation of the visit and work on the lectures.The technology of designing the educational process in the conditions of the mixed training is proposed, applying the technological map.The technological map is presented in the form of stages of designing the educational process, including recommendations on the use of

Full Text Available Abstract Many lecture recording and presentation systems transmit slides or chalkboard content along with a small video of the instructor. As a result, two areas of the screen are competing for the viewer's attention, causing the widely known split-attention effect. Face and body gestures, such as pointing, do not appear in the context of the slides or the board. To eliminate this problem, this article proposes to extract the lecturer from the video stream and paste his or her image onto the board or slide image. As a result, the lecturer acting in front of the board or slides becomes the center of attention. The entire lecture presentation becomes more human-centered. This article presents both an analysis of the underlying psychological problems and an explanation of signal processing techniques that are applied in a concrete system. The presented algorithm is able to extract and overlay the lecturer online and in real time at full video resolution.

CDKN1C, also known as p57 kip2 , is considered to be a potential tumor suppressor implicated in several kinds of human cancers. However, the current knowledge of CDKN1C in breast cancer remains obscure. In the present study, we demonstrated that CDKN1C was dramatically downregulated in breast cancer compared with normal tissues by using real-time quantitative polymerase chain reaction, western blot and two public data portals: The Cancer Genome Atlas (TCGA) and Oncomine datasets. Moreover, the expression of CDKN1C was correlated with age and tumor size in the TCGA cohort containing 708 cases of breast cancer. Low expression of CDKN1C was significantly associated with poor overall survival (OS) in the TCGA cohort and validated cohort composed of 1402 patients. Multivariate Cox regression analysis indicated that CDKN1C was an independent prognostic factor for worse OS (HR = 1.78, 95% CI: 1.09-2.89, p = 0.020). Furthermore, gene set enrichment analysis (GSEA) revealed that CDKN1C was significantly correlated with gene signatures involving DNA repair, cell cycle, glycolysis, adipogenesis, and two critical signaling pathways mTORC1 and PI3K/Akt/mTOR. In conclusion, our data suggested an essential role of CDKN1C in the tumorgenesis of breast cancer. Targeting CDKN1C may be a promising strategy for anticancer therapeutics.

Diversity dynamics operating between students lecturers and management in a historically Black university: The lecturers perspective

Directory of Open Access Journals (Sweden)

Michelle S. May

2012-03-01

Research purpose: The purpose of the research was to describe the experiences of nine lecturers in a particular HBU. This was undertaken to analyse and interpret the conscious and unconscious diversity dynamics operating in the relationship between the students, lecturers and management, from the lecturers’ perspective. Motivation for the study: The researcher was interested in the nature of the diversity dynamics operating in the relationship between students, lecturers and management in an HBU, as a platform towards understanding diversity dynamics in educational institutions and South African organisations. Research design, approach and method: Qualitative and descriptive research approaches were used. Hermeneutic phenomenology, using the systems psychodynamic perspective, allowed for the description and interpretation of diversity dynamics operating in the relationship between the students, lecturers and management. The data were obtained through in-depth interviews with nine lecturers. Thematic analysis resulted in two broad themes for which a discussion was provided and a research hypothesis formulated. Main findings: Two broad themes manifested, firstly diversity characteristics and secondly struggle skills entrenching the Black and White divide. Practical/managerial implications: The research highlighted the importance of understanding the diversity dynamics operating in the relationship between students, lecturers and management. This was in order to develop our understanding of diversity dynamics operating in educational institutions specifically, and organisations in general. Contribution/value-add: The understanding about diversity dynamics is available for application, by lecturers and management, to form a different understanding of conscious and unconscious factors impacting on the relationship between the three stakeholders, and subsequently the effectiveness of the three stakeholders in their respective roles. This understanding can also be

The energy utilities are working in an area of the community confronted by critical questions. The motto fo the 2nd IZE Communications Day proceedings was: 'Energy and the Environment - Public relations in the area of tension between Ecology and Economy'. It was a meeting of domestic and international business directors, politicians, public-relations specialists and journalists. The main concern of the lectures, discussions, workshops and conversation topics was how communication with the medium could be improved, thus enhancing their image in the press, on the radio and television. Top editors from the leading newspapers have strated and discussed their policy. A workshop case-study showed how readily the credibility and acceptance of the energy and environment sector could be improved through longterm, honest, dialogue-oriented and professional public relations work.

Argonne lectures on particles accelerator magnets

The quest for elementary particles has promoted the development of particle accelerators producing beams of increasingly higher energies. In a synchrotron, the particle energy is directly proportional to the product of the machine's radius times the bending magnets' field strength. Present proton experiments at the TeV scale require facilities with circumferences ranging from a few to tens of kilometers and relying on a large number (several hundred to several thousand) high field dipole magnets and high field gradient quadrupole magnets. These electro-magnets use high-current-density, low-critical-temperature superconducting cables and are cooled down at liquid helium temperature. They are among the most costly and the most challenging components of the machine. After explaining what are the various types of accelerator magnets and why they are needed (lecture 1), we briefly recall the origins of superconductivity and we review the parameters of existing superconducting particle accelerators (lecture 2). Then, we review the superconducting materials that are available at industrial scale (chiefly, NbTi and Nb 3 Sn) and we explain in details the manufacturing of NbTi wires and cables (lecture 3). We also present the difficulties of processing and insulating Nb 3 Sn conductors, which so far have limited the use of this material in spite of its superior performances. We continue by discussing the two dimensional current distributions which are the most appropriate for generating pure dipole and quadrupole fields and we explain how these ideal distributions can be approximated by so called cosθ and cos 2θ coil designs (lecture 4). We also present a few alternative designs which are being investigated and we describe the difficulties of realizing coil ends. Next, we present the mechanical design concepts that are used in existing accelerator magnets (lecture 5) and we describe how the magnets are assembled (lecture 6).

Full Text Available Recording lectures using video lecture capture software and making them available for students to watch anytime, from anywhere, has become a common practice in many universities across many disciplines. The software has become increasingly easy to use and is commonly provided and maintained by higher education institutions. Several studies have reported that students use lecture capture to enhance their learning and study for assessments, as well as to catch up on material they miss when they cannot attend class due to extenuating circumstances. Furthermore, students with disabilities and students from non-English Speaking Backgrounds (NESB may benefit from being able to watch the video lecture captures at their own pace. Yet, the effect of this technology on class attendance remains a controversial topic and largely unexplored in undergraduate microbiology education. Here, we show that when video lecture captures were available in our large enrollment general microbiology courses, attendance did not decrease. In fact, the majority of students reported that having the videos available did not encourage them to skip class, but rather they used them as a study tool. When we surveyed NESB students and nontraditional students about their attitudes toward this technology, they found it helpful for their learning and for keeping up with the material.

Full Text Available Abstract Background Electronic Voting Systems have been used for education in a variety of disciplines. Outcomes from these studies have been mixed. Because results from these studies have been mixed, we examined whether an EVS system could enhance a lecture's effect on educational outcomes. Methods A cohort of 127 Year 5 medical students at the University of Adelaide was stratified by gender, residency status and academic record then randomised into 2 groups of 64 and 63 students. Each group received consecutive 40-minute lectures on two clinical topics. One group received the EVS for both topics. The other group received traditional teaching only. Evaluation was undertaken with two, 15-question multiple-choice questionnaires (MCQ assessing knowledge and problem solving and undertaken as a written paper immediately before and after the lectures and repeated online 8–12 weeks later. Standardised institutional student questionnaires were completed for each lecture and independent observers assessed student behaviour during the lectures. Lecturer's opinions were assessed by a questionnaire developed for this study. Results Two-thirds of students randomised to EVS and 59% of students randomised to traditional lectures attended. One-half of the students in the EVS group and 41% in the traditional group completed all questionnaires. There was no difference in MCQ scores between EVS and traditional lectures (p = 0.785. The cervical cancer lectures showed higher student ranking in favour of EVS in all parameters. The breast cancer lectures showed higher ranking in favour of traditional lectures in 5 of 7 parameters (p Conclusion In this setting, EVS technology used in large group lectures did not offer significant advantages over the more traditional lecture format.

Marshall, Leisa L; Nykamp, Diane L; Momary, Kathryn M

2014-12-15

To compare the impact of 2 different teaching and learning methods on student mastery of learning objectives in a pharmacotherapy module in the large classroom setting. Two teaching and learning methods were implemented and compared in a required pharmacotherapy module for 2 years. The first year, multiple interactive mini-cases with inclass individual assessment and an abbreviated lecture were used to teach osteoarthritis; a traditional lecture with 1 inclass case discussion was used to teach gout. In the second year, the same topics were used but the methods were flipped. Student performance on pre/post individual readiness assessment tests (iRATs), case questions, and subsequent examinations were compared each year by the teaching and learning method and then between years by topic for each method. Students also voluntarily completed a 20-item evaluation of the teaching and learning methods. Postpresentation iRATs were significantly higher than prepresentation iRATs for each topic each year with the interactive mini-cases; there was no significant difference in iRATs before and after traditional lecture. For osteoarthritis, postpresentation iRATs after interactive mini-cases in year 1 were significantly higher than postpresentation iRATs after traditional lecture in year 2; the difference in iRATs for gout per learning method was not significant. The difference between examination performance for osteoarthritis and gout was not significant when the teaching and learning methods were compared. On the student evaluations, 2 items were significant both years when answers were compared by teaching and learning method. Each year, students ranked their class participation higher with interactive cases than with traditional lecture, but both years they reported enjoying the traditional lecture format more. Multiple interactive mini-cases with an abbreviated lecture improved immediate mastery of learning objectives compared to a traditional lecture format, regardless of

CDKN1C/p57kip2 is a candidate tumor suppressor gene in human breast cancer

CDKN1C (also known as p57 KIP2 ) is a cyclin-dependent kinase inhibitor previously implicated in several types of human cancer. Its family members (CDKN1A/p21 CIP1 and B/p27 KIP1 ) have been implicated in breast cancer, but information about CDKN1C's role is limited. We hypothesized that decreased CDKN1C may be involved in human breast carcinogenesis in vivo. We determined rates of allele imbalance or loss of heterozygosity (AI/LOH) in CDKN1C, using an intronic polymorphism, and in the surrounding 11p15.5 region in 82 breast cancers. We examined the CDKN1C mRNA level in 10 cancers using quantitative real-time PCR (qPCR), and the CDKN1C protein level in 20 cancers using immunohistochemistry (IHC). All samples were obtained using laser microdissection. Data were analyzed using standard statistical tests. AI/LOH at 11p15.5 occurred in 28/73 (38%) informative cancers, but CDKN1C itself underwent AI/LOH in only 3/16 (19%) cancers (p = ns). In contrast, CDKN1C mRNA levels were reduced in 9/10 (90%) cancers (p < 0.0001), ranging from 2–60% of paired normal epithelium. Similarly, CDKN1C protein staining was seen in 19/20 (95%) cases' normal epithelium but in only 7/14 (50%) cases' CIS (p < 0.004) and 5/18 (28%) cases' IC (p < 0.00003). The reduction appears primarily due to loss of CDKN1C expression from myoepithelial layer cells, which stained intensely in 17/20 (85%) normal lobules, but in 0/14 (0%) CIS (p < 0.00001). In contrast, luminal cells displayed less intense, focal staining fairly consistently across histologies. Decreased CDKN1C was not clearly associated with tumor grade, histology, ER, PR or HER2 status. CDKN1C is expressed in normal epithelium of most breast cancer cases, mainly in the myothepithelial layer. This expression decreases, at both the mRNA and protein level, in the large majority of breast cancers, and does not appear to be mediated by AI/LOH at the gene. Thus, CDKN1C may be a breast cancer tumor suppressor

Much of this material was instrumental in many areas of mathematics, in particular in the theory of algebraic groups and in the subsequent classification of finite groups. This posthumous edition incorporates additions and corrections prepared by the author during his retirement, including a new introductory chapter. A bibliography and editorial notes have also been added. This is a great unsurpassed introduction to the subject of Chevalley groups that influenced generations of mathematicians. I would recommend it to anybody whose interests include group theory. -Efim Zelmanov, University of California, San Diego Robert Steinberg's lectures on Chevalley groups were given at Yale University in 1967.

Lectures on functor homology

CERN Document Server

Touzé, Antoine

2015-01-01

This book features a series of lectures that explores three different fields in which functor homology (short for homological algebra in functor categories) has recently played a significant role. For each of these applications, the functor viewpoint provides both essential insights and new methods for tackling difficult mathematical problems. In the lectures by Aurélien Djament, polynomial functors appear as coefficients in the homology of infinite families of classical groups, e.g. general linear groups or symplectic groups, and their stabilization. Djament’s theorem states that this stable homology can be computed using only the homology with trivial coefficients and the manageable functor homology. The series includes an intriguing development of Scorichenko’s unpublished results. The lectures by Wilberd van der Kallen lead to the solution of the general cohomological finite generation problem, extending Hilbert’s fourteenth problem and its solution to the context of cohomology. The focus here is o...

Lectures on quasiconformal mappings

CERN Document Server

Ahlfors, Lars V

2006-01-01

Lars Ahlfors's Lectures on Quasiconformal Mappings, based on a course he gave at Harvard University in the spring term of 1964, was first published in 1966 and was soon recognized as the classic it was shortly destined to become. These lectures develop the theory of quasiconformal mappings from scratch, give a self-contained treatment of the Beltrami equation, and cover the basic properties of Teichm�ller spaces, including the Bers embedding and the Teichm�ller curve. It is remarkable how Ahlfors goes straight to the heart of the matter, presenting major results with a minimum set of prerequisites. Many graduate students and other mathematicians have learned the foundations of the theories of quasiconformal mappings and Teichm�ller spaces from these lecture notes. This edition includes three new chapters. The first, written by Earle and Kra, describes further developments in the theory of Teichm�ller spaces and provides many references to the vast literature on Teichm�ller spaces and quasiconformal ...

Portraiture in the Large Lecture: Storying One Chemistry Professor's Practical Knowledge

Science.gov (United States)

Eddleton, Jeannine E.

Practical knowledge, as defined by Freema Elbaz (1983), is a complex, practically oriented set of understandings which teachers use to actively shape and direct their work. The goal of this study is the construction of a social science portrait that illuminates the practical knowledge of a large lecture professor of general chemistry at a public research university in the southeast. This study continues Elbaz's (1981) work on practical knowledge with the incorporation of a qualitative and intentionally interventionist methodology which "blurs the boundaries of aesthetics and empiricism in an effort to capture the complexity, dynamics, and subtlety of human experience and organizational life," (Lawrence-Lightfoot & Davis, 1997). This collection of interviews, observations, writings, and reflections is designed for an eclectic audience with the intent of initiating conversation on the topic of the large lecture and is a purposeful attempt to link research and practice. Social science portraiture is uniquely suited to this intersection of researcher and researched, the perfect combination of methodology and analysis for a project that is both product and praxis. The following research questions guide the study. • Are aspects of Elbaz's practical knowledge identifiable in the research conversations conducted with a large lecture college professor? • Is practical knowledge identifiable during observations of Patricia's large lecture? Freema Elbaz conducted research conversations with Sarah, a high school classroom and writing resource teacher who conducted much of her teaching work one on one with students. Patricia's practice differs significantly from Sarah's with respect to subject matter and to scale.

"Annotated Lectures": Student-Instructor Interaction in Large-Scale Global Education

Directory of Open Access Journals (Sweden)

Roger Diehl

2009-10-01

Full Text Available We describe an "Annotated Lectures" system, which will be used in a global virtual teaching and student collaboration event on embodied intelligence presented by the University of Zurich. The lectures will be broadcasted via video-conference to lecture halls of different universities around the globe. Among other collaboration features, an "Annotated Lectures" system will be implemented in a 3D collaborative virtual environment and used by the participating students to make annotations to the video-recorded lectures, which will be sent to and answered by their supervisors, and forwarded to the lecturers in an aggregated way. The "Annotated Lectures" system aims to overcome the issues of limited studentinstructor interaction in large-scale education, and to foster an intercultural and multidisciplinary discourse among students who review the lectures in a group. After presenting the concept of the "Annotated Lectures" system, we discuss a prototype version including a description of the technical components and its expected benefit for large-scale global education.

Interactive lectures: Clickers or personal devices?

Science.gov (United States)

Morrell, Lesley J; Joyce, Domino A

2015-01-01

Audience response systems ('clickers') are frequently used to promote participation in large lecture classes, and evidence suggests that they convey a number of benefits to students, including improved academic performance and student satisfaction. The limitations of these systems (such as limited access and cost) can be overcome using students' personal electronic devices, such as mobile phones, tablets and laptops together with text message, web- or app-based polling systems. Using questionnaires, we compare student perceptions of clicker and smartphone based polling systems. We find that students prefer interactive lectures generally, but those that used their own device preferred those lectures over lectures using clickers. However, device users were more likely to report using their devices for other purposes (checking email, social media etc.) when they were available to answer polling questions. These students did not feel that this distracted them from the lecture, instead, concerns over the use of smartphones centred around increased battery usage and inclusivity for students without access to suitable technology. Our results suggest that students generally preferred to use their own devices over clickers, and that this may be a sensible way to overcome some of the limitations associated with clickers, although issues surrounding levels of distraction and the implications for retention and recall of information need further investigation.

Active Learning in ASTR 101 Lectures

Science.gov (United States)

Deming, Grace L.

1998-12-01

The lecture is the most common teaching method used at colleges and universities, but does this format facilitate student learning? Lectures can be brilliantly delivered, but they are received by a passive audience. As time passes during a lecture, student attention and effective notetaking diminish. Many students become more interested in a subject and retain information longer in courses that rely on active rather than passive teaching methods. Interactive teaching strategies such as the think-pair-share-(write), the 3-minute paper, and the misconception confrontation can be used to actively engage students during lecture. As a cooperative learning strategy, the think-pair-share-(write) technique requires active discussion by everyone in the class. The "write" component structures individual accountability into the activity. The 3-minute paper is an expansion of the standard 1-minute paper feedback technique, but is required of all students rather than voluntary or anonymous. The misconception confrontation technique allows students to focus on how their pre- conceived notions differ from the scientific explanation. These techniques can be easily adopted by anyone currently using a standard lecture format for introductory astronomy. The necessary components are a commitment by the instructor to require active participation by all students and a willingness to try new teaching methods.

Milner-Bolotin, Marina M.; Kotlicki, A.; Rieger, G.; Bates, F.; Moll, R.; McPhee, K.; Nashon, S.

2006-12-01

We describe Interactive Lecture Experiments (ILE), which build on Interactive Lecture Demonstrations proposed by Sokoloff and Thornton (2004) and extends it by providing students with the opportunity to analyze experiments demonstrated in the lecture outside of the classroom. Real time experimental data is collected, using Logger Pro combined with the digital video technology. This data is uploaded to the Internet and made available to the students for further analysis. Student learning is assessed in the following lecture using conceptual questions (clickers). The goal of this project is to use ILE to make large lectures more interactive and promote student interest in science, critical thinking and data analysis skills. We report on the systematic study conducted using the Colorado Learning Attitudes about Science Survey, Force Concept Inventory, open-ended physics problems and focus group interviews to determine the impact of ILE on student academic achievement, motivation and attitudes towards physics. Three sections of students (750 students) experienced four ILE experiments. The surveys were administered twice and academic results for students who experienced the ILE for a particular topic were compared to the students, from a different section, who did not complete the ILE for that topic. Additional qualitative data on students’ attitudes was collected using open ended survey questions and interviews. We will present preliminary conclusions about the role of ILEs as an effective pedagogy in large introductory physics courses. Sokoloff, D.R. and R.K. Thornton (2004).

Tang, Brandon; Coret, Alon; Qureshi, Aatif; Barron, Henry; Ayala, Ana Patricia; Law, Marcus

2018-04-10

The adoption of the flipped classroom in undergraduate medical education calls on students to learn from various self-paced tools-including online lectures-before attending in-class sessions. Hence, the design of online lectures merits special attention, given that applying multimedia design principles has been shown to enhance learning outcomes. The aim of this study was to understand how online lectures have been integrated into medical school curricula, and whether published literature employs well-accepted principles of multimedia design. This scoping review followed the methodology outlined by Arksey and O'Malley (2005). Databases, including MEDLINE, PsycINFO, Education Source, FRANCIS, ERIC, and ProQuest, were searched to find articles from 2006 to 2016 related to online lecture use in undergraduate medical education. In total, 45 articles met our inclusion criteria. Online lectures were used in preclinical and clinical years, covering basic sciences, clinical medicine, and clinical skills. The use of multimedia design principles was seldom reported. Almost all studies described high student satisfaction and improvement on knowledge tests following online lecture use. Integration of online lectures into undergraduate medical education is well-received by students and appears to improve learning outcomes. Future studies should apply established multimedia design principles to the development of online lectures to maximize their educational potential. ©Brandon Tang, Alon Coret, Aatif Qureshi, Henry Barron, Ana Patricia Ayala, Marcus Law.

Significance assessment of the external control effects of lecturers

Directory of Open Access Journals (Sweden)

Kurbatova Margarita, V.

2015-06-01

Full Text Available The state policy regarding higher education has changed in the last decade. These changes were part of the efficiency programs of the public sector. Governments of different countries ruined previously existing system of higher education state regulation and attempted to build the quasi-market structure in the higher education industry. Such transformations served as timely and progressive reforms in the recent studies of the economics of education. Substitution of bureaucratic management mechanisms and modern competition managerial tools are articulated. Economic and institutional and sociological studies on the effects of the introduction of quasi-markets and managerial tools in higher education governance oppose to orthodox market approach. They drew attention to the fact that evaluation methods and improve the effectiveness of organizations and employees that are typical of the private sector often produce results that differ from those in the public sector. To assess the consequences of the introduction of managerial tools of external control activities of university lecturers used a methodology based on the allocation of the individual structural components (effects and building on their basis of a multi-level hierarchical model in the research. Each component of the model (single effect is characterized by a degree of significance (importance and the degree of severity. The results of the systematization and assessment of the significance of the effects of external control activity of lecturers of Russian universities implemented in conditions of quasi-market mechanisms of the higher education system are highlighted in the paper.

On performing concepts during science lectures

Science.gov (United States)

Pozzer-Ardenghi, Lilian; Roth, Wolff-Michael

2007-01-01

When lecturing, teachers make use of both verbal and nonverbal communication. What is called teaching, therefore, involves not only the words and sentences a teacher utters and writes on the board during a lesson, but also all the hands/arms gestures, body movements, and facial expressions a teacher performs in the classroom. All of these communicative modalities constitute resources that are made available to students for making sense of and learning from lectures. Yet in the literature on teaching science, these other means of communication are little investigated and understood - and, correspondingly, they are undertheorized. The purpose of this position paper is to argue for a different view of concepts in lectures: they are performed simultaneously drawing on and producing multiple resources that are different expressions of the same holistic meaning unit. To support our point, we provide examples from a database of 26 lectures in a 12th-grade biology class, where the human body was the main topic of study. We analyze how different types of resources - including verbal and nonverbal discourse and various material artifacts - interact during lectures. We provide evidence for the unified production of these various sense-making resources during teaching to constitute a meaning unit, and we emphasize particularly the use of gestures and body orientations inside this meaning unit. We suggest that proper analyses of meaning units need to take into account not only language and diagrams but also a lecturer's pointing and depicting gestures, body positions, and the relationships between these different modalities. Scientific knowledge (conceptions) exists in the concurrent display of all sense-making resources, which we, following Vygotsky, understand as forming a unit (identity) of nonidentical entities.

Retinoic Acid Signaling Mediates Hair Cell Regeneration by Repressing p27kip and sox2 in Supporting Cells.

Science.gov (United States)

Rubbini, Davide; Robert-Moreno, Àlex; Hoijman, Esteban; Alsina, Berta

2015-11-25

During development, otic sensory progenitors give rise to hair cells and supporting cells. In mammalian adults, differentiated and quiescent sensory cells are unable to generate new hair cells when these are lost due to various insults, leading to irreversible hearing loss. Retinoic acid (RA) has strong regenerative capacity in several organs, but its role in hair cell regeneration is unknown. Here, we use genetic and pharmacological inhibition to show that the RA pathway is required for hair cell regeneration in zebrafish. When regeneration is induced by laser ablation in the inner ear or by neomycin treatment in the lateral line, we observe rapid activation of several components of the RA pathway, with dynamics that position RA signaling upstream of other signaling pathways. We demonstrate that blockade of the RA pathway impairs cell proliferation of supporting cells in the inner ear and lateral line. Moreover, in neuromast, RA pathway regulates the transcription of p27(kip) and sox2 in supporting cells but not fgf3. Finally, genetic cell-lineage tracing using Kaede photoconversion demonstrates that de novo hair cells derive from FGF-active supporting cells. Our findings reveal that RA has a pivotal role in zebrafish hair cell regeneration by inducing supporting cell proliferation, and shed light on the underlying transcriptional mechanisms involved. This signaling pathway might be a promising approach for hearing recovery. Hair cells are the specialized mechanosensory cells of the inner ear that capture auditory and balance sensory input. Hair cells die after acoustic trauma, ototoxic drugs or aging diseases, leading to progressive hearing loss. Mammals, in contrast to zebrafish, lack the ability to regenerate hair cells. Here, we find that retinoic acid (RA) pathway is required for hair cell regeneration in vivo in the zebrafish inner ear and lateral line. RA pathway is activated very early upon hair cell loss, promotes cell proliferation of progenitor cells

Maryam Rahimirad

2015-06-01

Full Text Available Academic listening skill is an indispensable necessity for English for academic purposes (EAP students in English-medium universities and also critical for their future success in comprehending conference lectures. But due to the specific nature of such academic lectures, nonnative students all too often face challenges in getting a full command of this task. This study investigates the challenges of listening to academic lectures and the impact of related metacognitive strategies on academic lecture listening comprehension on a group of Iranian learners in an EAP workshop. Fifteen academic staff who took part in two intact classes at the University of Qom, Iran, were randomly assigned to treatment (N = 8 and control (N = 7 groups. The treatment group received 16 hr of metacognitive strategy instruction based on the models proposed by Vandergrift during academic listening instruction, while the control group was just exposed to academic lectures with no explicit strategy instruction. The academic listening sections of the British International English Language Testing System (IELTS were utilized to measure the listening comprehension of both groups before and after the treatment. The results of the data analysis determined that the experimental group significantly outperformed the control group in the listening posttest. The interviews before and after the treatment revealed details of challenges in academic lecture comprehension and also shed light on the perception of the learners regarding metacognitive strategy instruction and the frequency of main metacognitive strategies used in comprehending academic lectures.

Science for Alaska: Public Understanding of Science D. L. Campbell11University of Alaska Fairbanks, USA Around 200 people brave 40-below-zero temperatures to listen to university researchers and scientists give lectures about their work at an event called the Science for Alaska Lecture Series, hosted by the University of Alaska Fairbanks Geophysical Institute. It is held once a week, for six weeks during the coldest part of a Fairbanks, Alaska, winter. The topics range from space physics to remote sensing. The lectures last for 45 minutes with 15 minutes for audience questions and answers. It has been popular for about 20 years and is one of many public outreach efforts of the institute. The scientists are careful in their preparations for presentations and GI's Public Relations staff chooses the speakers based on topic, diversity and public interest. The staff also considers the speaker's ability to speak to a general audience, based on style, clarity and experience. I conducted a qualitative research project to find out about the people who attended the event, why they attend and what they do with the information they hear about. The participants were volunteers who attended the event and either stayed after the lectures for an interview or signed up to be contacted later. I used used an interview technique with open-ended questions, recorded and transcribed the interview. I identified themes in the interviews, using narrative analysis. Preliminary data show that the lecture series is a form of entertainment for people who are highly educated and work in demanding and stressful jobs. They come with family and friends. Sometimes it's a date with a significant other. Others want to expose their children to science. The findings are in keeping with the current literature that suggests that public events meant to increase public understanding of science instead draws like-minded people. The findings are different from Campbell's hypothesis that attendance was based

Should Lecture Recordings Be Mandated in Dental Schools? Two Viewpoints: Viewpoint 1: Lecture Recordings Should Be Mandatory in U.S. Dental Schools and Viewpoint 2: Lecture Recordings Should Not Be Mandatory in U.S. Dental Schools.

Science.gov (United States)

Zandona, Andrea Ferreira; Kinney, Janet; Seong, WookJin; Kumar, Vandana; Bendayan, Alexander; Hewlett, Edmond

2016-12-01

Transcription or recording of lectures has been in use for many years, and with the availability of high-fidelity recording, the practice is now ubiquitous in higher education. Since technology has permeated education and today's tech-savvy students have expectations for on-demand learning, dental schools are motivated to record lectures, albeit with positive and negative implications. This Point/Counterpoint article addresses the question of whether lecture recording should be mandatory in U.S. dental schools. Viewpoint 1 supports the statement that lecture recording should be mandatory. Proponents of this viewpoint argue that the benefits-notably, student satisfaction and potential for improvement in student performance-outweigh concerns. Viewpoint 2 takes the opposite position, arguing that lecture recording decreases students' classroom attendance and adversely affects the morale of educators. Additional arguments against mandatory lecture recordings involve the expense of incorporating technology that requires ongoing support.

Using lecture capture: a qualitative study of nursing faculty's experience.

Science.gov (United States)

Freed, Patricia E; Bertram, Julie E; McLaughlin, Dorcas E

2014-04-01

As lecture capture technology becomes widely available in schools of nursing, faculty will need to master new technological skills and make decisions about recording their classroom lectures or other activities. This study sought to understand faculty's experience of using a new lecture capture system. This qualitative study used Kruger's systematic approach to explore undergraduate nursing faculty's first-time experience using a lecture capture system purchased by the university. Four focus groups were conducted with a total of fourteen undergraduate faculty using lecture capture for the first-time. The interviews were recorded and transcribed and then analyzed by the researchers. Four themes were identified from the faculty interviews. Two of the themes expressed faculty's concerns about the teaching role, and two themes expressed the faculty's concerns about student learning. Participants experienced stress when learning to use the new lecture capture technology and struggled to resolve it with their own beliefs and teaching values. The impact of lecture capture on student learning, impact on class attendance, and the promotion of a culture of lecturing were revealed as important issues to consider when lecture capture becomes available. © 2013.

Feinstein / CPPM, Marseille, F The fact that the mass of the visible stars could not account for the gravitational cohesion of the galaxy clusters was the first manifestation of non-radiating matter in the Universe. Since then, many observations imply that most of the matter is indeed dark. Its nature is still unknown and likely to have several contributions. Recent results indicate that most of it may not be composed of normal matter. These lectures will review the experimental methods, which have been developed to unravel this 70-year long mystery and confront their results with the current theoretical framework of cosmology.

2017-01-01

Full Text Available In the context of modernization of the Russian system of higher education, it is necessary to analyze the working time of the university lecturers, taking into account both basic job functions as the university lecturer, and others.The mathematical problem is presented for the optimal working time planning for the university lecturers. The review of the documents, native and foreign works on the study is made. Simulation conditions, based on analysis of the subject area, are defined. Models of optimal working time sharing of the university lecturers («the second half of the day» are developed and implemented in the system MathCAD. Optimal solutions have been obtained.Three problems have been solved:1 to find the optimal time sharing for «the second half of the day» in a certain position of the university lecturer;2 to find the optimal time sharing for «the second half of the day» for all positions of the university lecturers in view of the established model of the academic load differentiation;3 to find the volume value of the non-standardized part of time work in the department for the academic year, taking into account: the established model of an academic load differentiation, distribution of the Faculty number for the positions and the optimal time sharing «the second half of the day» for the university lecturers of the department.Examples are given of the analysis results. The practical application of the research: the developed models can be used when planning the working time of an individual professor in the preparation of the work plan of the university department for the academic year, as well as to conduct a comprehensive analysis of the administrative decisions in the development of local university regulations.

Neoadjuvant chemotherapy (NAC) with taxanes followed by fluorouracil, epirubicin, and cyclophosphamide (FEC), and concurrent trastuzumab is a potent regimen for HER2 over-expressing breast cancer. A high pathological complete response (pCR) rate has been achieved using this regimen; however, the predictive factors and prognostic effects of pCR currently remain unclear. In the present study, we determined whether pCR was related to histological grade (HG) and several biological factors including p27 Kip1 . We also assessed the prognosis of the pCR and non-pCR groups, and expected differences between those positive and negative for lymph node metastasis after chemotherapy. A total of 129 Japanese women with HER2-positive invasive breast cancer received either paclitaxel or docetaxel followed by FEC, with the concomitant administration of trastuzumab. The statuses of HG, ER, PgR, Ki67, and p27 Kip1 were evaluated to determine their relationship with pCR. Relapse-free survival (RFS) and overall survival (OS) were also analyzed for their relationship with pCR and pathological nodal involvement. pCR was obtained in 84 out of 129 patients and the pCR rate was 65.1 %. The pCR rates related to 5 factors were as follows: HG (grade 3, 70.0 % vs. grades 1–2, 36.8 %), ER (negative, 78.6 % vs. positive, 40.0 %), PgR (negative, 75.3 % vs. positive, 38.9 %), Ki67 (high, 72.0 % vs. low, 47.2 %), and p27 Kip1 (low, 71.0 % vs. high, 50.0 %). RFS was significantly better in the pCR group than in the non-pCR group (p = 0.018). Patients with remaining nodal disease in the pCR group had worse OS (p = 0.0002). High-HG, low-ER, low-PgR, high-Ki67, and low-p27 Kip1 were identified as predictive factors of pCR in NAC with trastuzumab, while pCR and negative nodes were predictive of better survivals.

A comparative study of traditional lecture methods and interactive lecture methods in introductory geology courses for non-science majors at the college level

Science.gov (United States)

Hundley, Stacey A.

In recent years there has been a national call for reform in undergraduate science education. The goal of this reform movement in science education is to develop ways to improve undergraduate student learning with an emphasis on developing more effective teaching practices. Introductory science courses at the college level are generally taught using a traditional lecture format. Recent studies have shown incorporating active learning strategies within the traditional lecture classroom has positive effects on student outcomes. This study focuses on incorporating interactive teaching methods into the traditional lecture classroom to enhance student learning for non-science majors enrolled in introductory geology courses at a private university. Students' experience and instructional preferences regarding introductory geology courses were identified from survey data analysis. The information gained from responses to the questionnaire was utilized to develop an interactive lecture introductory geology course for non-science majors. Student outcomes were examined in introductory geology courses based on two teaching methods: interactive lecture and traditional lecture. There were no significant statistical differences between the groups based on the student outcomes and teaching methods. Incorporating interactive lecture methods did not statistically improve student outcomes when compared to traditional lecture teaching methods. However, the responses to the survey revealed students have a preference for introductory geology courses taught with lecture and instructor-led discussions and students prefer to work independently or in small groups. The results of this study are useful to individuals who teach introductory geology courses and individuals who teach introductory science courses for non-science majors at the college level.

Lecture One: Rediscovering Darwin for theology – Rethinking human personhood

Directory of Open Access Journals (Sweden)

J. Wentzel van Huyssteen

2017-11-01

Full Text Available In a series of three articles, presented at the Goshen Annual Conference on Science and Religion in 2015, with the theme ‘Interdisciplinary Theology and the Archeology of Personhood’, J. Wentzel van Huyssteen considers the problem of human evolution – also referred to as ‘the archaeology of personhood’ – and its broader impact on theological anthropology. These Goshen Lectures explore the potentiality that the history of human evolution provides bridge theories to theological anthropology and thus to a positive and constructive way of appropriating Darwinian thought for a public, interdisciplinary Christian theology. Lecture One tracks a select number of contemporary proposals for the evolution of aspects of human personhood. These aspects were of significance for Darwin: the evolution of cognition; the evolution of imagination, music and language; the evolution of morality; and the evolution of the religious disposition. The article acknowledges the close ties to hominid ancestors and focuses on the emergence of human distinctiveness, consciousness and personhood, and the propensity for religious awareness and experience.

Hypertension or most commonly known as high blood pressure is a non-communicable disease affecting to health of people with non-detectible cause (primary) and some with determined causes (secondary). The prevalence of hypertension morbidity was very high globally, the consequences of the disease if not been treated is death. The purpose of this study was to determine the relationship between hypertension and anthropometry measurements such as weight, height and body mass index among academic staff in public universities in Malaysia. The design for this study was cross-sectional and the method for data collection was mailed questionnaire. The initial sample size for this study was 189, therefore, 500 questionnaires were distributed to randomly selected academicians in public universities, colleges and polytechnics in Malaysia. However, only 101 questionnaires were returned and were analysed in this study. The target population were academicians which includes lecturers and senior lecturers in public universities in Malaysia. The methods of analysis employed was logistic regression and frequency analysis. It was found that weight, height and body mass index (BMI) have no significant relationship with hypertension but based on the Crude Odd Ratio, all these three anthropometry measures showed that there were protective risk of hypertension among lecturers and senior lecturers in public university, Malaysia. In a nutshell, there were no evidence to conclude that anthropometry measurements can affect hypertension status among academic staff at public university.

Oxidized modifications of LDL (oxLDL) play a key role in the development of endothelial dysfunction and atherosclerosis. However, the underlying mechanisms of oxLDL-mediated cellular behavior are not completely understood. Here, we compared the effects of two major types of oxLDL, copper-oxidized LDL (Cu 2+ -oxLDL) and lipoxygenase-oxidized LDL (LPO-oxLDL), on proliferation of human aortic endothelial cells (HAECs). Cu 2+ -oxLDL enhanced HAECs' proliferation in a dose- and degree of oxidation-dependent manner. Similarly, LPO-oxLDL also enhanced HAEC proliferation. Mechanistically, both Cu 2+ -oxLDL and LPO-oxLDL enhance HAEC proliferation via activation of Rho, Akt phosphorylation, and a decrease in the expression of cyclin-dependent kinase inhibitor 1B (p27 kip1 ). Both Cu 2+ -oxLDL or LPO-oxLDL significantly increased Akt phosphorylation, whereas an Akt inhibitor, MK2206, blocked oxLDL-induced increase in HAEC proliferation. Blocking Rho with C3 or its downstream target ROCK with Y27632 significantly inhibited oxLDL-induced Akt phosphorylation and proliferation mediated by both Cu 2+ - and LPO-oxLDL. Activation of RhoA was blocked by Rho-GDI-1, which also abrogated oxLDL-induced Akt phosphorylation and HAEC proliferation. In contrast, blocking Rac1 in these cells had no effect on oxLDL-induced Akt phosphorylation or cell proliferation. Moreover, oxLDL-induced Rho/Akt signaling downregulated cell cycle inhibitor p27 kip1 Preloading these cells with cholesterol, however, prevented oxLDL-induced Akt phosphorylation and HAEC proliferation. These findings provide a new understanding of the effects of oxLDL on endothelial proliferation, which is essential for developing new treatments against neovascularization and progression of atherosclerosis.

Dynamic e-learning modules for student lecture preparation

Directory of Open Access Journals (Sweden)

Timothy McIntyre

2018-03-01

Full Text Available We have developed and demonstrated the effectiveness of a set of online interactive learning modules to accompany physics courses at first- and second-year university levels. Students access the modules prior to attending lectures to familiarize themselves with content which is then discussed and reaffirmed in class. Student surveys and access data show that students were much more likely to use material presented in this form, rather than a textbook, when preparing for lectures given in an active learning format. The students found that interactive simulations, videos of problem-solving approaches prepared by course staff, and quick-check immediate feedback questions were all useful tools for lecture preparation–none of which are available when using a traditional textbook for lecture preparation.

Full Text Available Video-linked lectures allow healthcare students across multiple sites, and between university and hospital bases, to come together for the purposes of shared teaching. Recording and streaming video-linked lectures allows students to view them at a later date and provides an additional resource to support student learning. As part of a UK Higher Education Academy-funded Pathfinder project, this study explored medical students' perceptions of video-linked lectures and video-streaming, and their impact on learning. The methodology involved semi-structured interviews with 20 undergraduate medical students across four sites and five year groups. Several key themes emerged from the analysis. Students generally preferred live lectures at the home site and saw interaction between sites as a major challenge. Students reported that their attendance at live lectures was not affected by the availability of streamed lectures and tended to be influenced more by the topic and speaker than the technical arrangements. These findings will inform other educators interested in employing similar video technologies in their teaching.Keywords: video-linked lecture; video-streaming; student perceptions; decisionmaking; cross-campus teaching.

The human anatomy, or in brief, the body structure has fascinated man for ages. Due to the information explosion and the increase in specializations, this knowledge is available in a very sketchy manner in high school biology courses. The first comprehensive course on the human anatomy is taught to the first year medical students in medical colleges. This is in keeping with the regulations of the Medical Council of India. The anatomy lecture classes occupy a considerable time of the course, to provide the students with an effective knowledge of the gross anatomy, histology, embryology and the clinical anatomy. On the other hand, the students' feedback regarding the lecture methods and the teaching environment is crucial in judging the efficacy of the present curriculum. To obtain the students' feedback about the environment of the lecture classes, as regards the venue, the teaching and learning aids which are used, the lecture class schedule of the university (the number of classes per week, the durations of the lecture classes, etc.) and the existing departmental practices (display of the class routine in advance, synchronization between the lecture and the practical classes), so that their suggestions could help the faculty in planning the most effective teaching procedures. A semi structured questionnaire was supplied to the students to get their feedback. Most of the students found the air conditioned seminar room's environment to be more comfortable and they supported the existing durations of the lecture hours with the combined use of chalk and a board and overhead projectors (OHPs). The perceptions of the learners helped in modifying the departmental practice in the desired way.

2016-09-01

Full Text Available At the present the Russian government is undertaking a higher education system reform actively introducing management tools of new public management. Implementation of these instruments is accompanied by the transformation of universities in the customer-oriented organizations and lecturers into the employees. There is a substitution of incentives based on the existing informal norms of academic standards and reputation mechanisms of control to the incentives based on the quasi-market conditions artificially generated by the state and corresponding to the mechanisms of external assessment and monitoring. Practices changing used by lecturers to follow their interests is the inevitable result and more widespread form is opportunism. The purpose of the paper is to characterize the forms of manifestation of opportunistic behavior of university lecturers emerging as a result of changes in the nature of lecturers’ contract in the conditions of university governance managerisation. The main forms of lecturers’ opportunism and assesses of its degree based on data analysis of the two waves of the expert survey on the problems of assessing the impact of implementation mechanisms of external evaluation of their activities and the questionnaire survey of lecturers more than 40 Russian universities of different status are described as well as lecturers’ strategy of behavior, which are presented as a combination of different severity practices used by opportunistic behavior is highlighted. It shows the relation between the non-observance of academic freedom and the choice of lecturers’ strategies conduct. It is proved that the lecturers of Russian universities depending on the accumulated stocks of human and social capital as well as the resource capacity of separate universities are choosing different strategies to follow their own interests, which differ in the level of shirking in different areas of activity.

Jen, Aaron; Webb, Emily M; Ahearn, Bren; Naeger, David M

2016-01-01

The didactic lecture remains one of the most popular teaching formats in medical education; yet, factors that most influence lecturing success in radiology education are unknown. The purpose of this study is to identify patterns of narrative student feedback that are associated with relatively higher and lower evaluation scores. All student evaluations from our core radiology elective during 1 year were compiled. All evaluation comments were tagged, to identify discrete descriptive concepts. Correlation coefficients were calculated, for each tag with mean evaluation scores. Tags that were the most strongly associated with the highest- versus lowest-rated (> or < 1 SD) lectures were identified. A total of 3,262 comments, on 273 lectures, rated by 77 senior medical students, were analyzed. The mean lecture score was 8.96 ± 0.62. Three tags were significantly positively correlated with lecture score: "interactive"; "fun/engaging"; and "practical/important content" (r = 0.39, r = 0.34, and r = 0.32, respectively; all P < .001). More tags (n = 12) were significantly negatively correlated with score; the three tags with the strongest such correlation were: "not interactive"; "poorly structured or unevenly paced"; and "content too detailed or abundant" (r = -0.44, r = -0.39, and r = -0.36, respectively; all P < .001). Analysis of only the highest- and lowest-rated lectures yielded similar results. Several factors were identified that were strongly associated with lecture score. Among the actionable characteristics, interactive lectures with appropriately targeted content (ie, practical/useful) were the most highly rated. Copyright © 2016 American College of Radiology.

2017-02-01

Full Text Available BACKGROUND The current generation is rightly described as generation M (edia highlighting the increasing time spent with media on any given day. The availability of mobiles and the absence of mobile jammers in lecture classes will seriously interfere with lecture attendance or concentration in lecture hours. We intend to take a survey on the level of social media use or use of smartphone for other non-academic uses by medical students during their lecture hours. We expect them to put forward their views as to how they perceive live lectures and what can be done to improve the effect of live lectures in this era of widespread and anytime media use. Aims of the study were- 1. To conduct a survey among medical students in preclinical postings regarding use of social media use during live lecture hours. 2. To assess their perception regarding conventional lecture duration and the factors, which could improve their concentration during lecture hours. MATERIALS AND METHODS A cross-sectional descriptive study was conducted among the participants. Approval was obtained from the Institutional Research Committee. All the 135 participants of the study were administered a semi-structured prevalidated questionnaire to assess their perception regarding live lecture and a survey regarding use of social media was taken. The collected data was entered into MS Excel and analysed using Epiinfo version 7. Percentages were used to quantify the results. Settings and Design- The study was conducted among third semester students attending pharmacology lectures in Government Medical College, Thrissur. RESULTS 77 (57% participants agreed of using social media regularly in lecture hours. Majority used it to chat or connect with friends and in gaming either because of addiction or to avoid boredom. They were a majority in opinion that the hot noon time lectures should be cut short in duration. They preferred the use of newer technology based methods to be adopted for

Hrepic, Zdeslav; Zollman, Dean A.; Sanjay Rebello, N.

2007-06-01

In spite of advances in physics pedagogy, the lecture is by far the most widely used format of instruction. We investigated students' understanding and perceptions of the content delivered during a physics lecture. A group of experts (physics instructors) also participated in the study as a reference for the comparison. During the study, all participants responded to a written conceptual survey on sound propagation. Next, they looked for answers to the survey questions in a videotaped lecture by a nationally known teacher. As they viewed the lecture, they indicated instances, if any, in which the survey questions were answered during the lecture. They also wrote down (and if needed, later explained) the answer, which they perceived was given by the instructor in the video lecture. Students who participated in the study were enrolled in a conceptual physics course and had already covered the topic in class before the study. We discuss and compare students' and experts' responses to the survey questions before and after the lecture.

Hessheimer, Heather M; Rogo, Ellen J; Howlett, Bernadette

2011-08-01

The purposes of this quasi-experimental, one-group crossover study were to determine the effect of questioning during dental hygiene lectures on low-level and high-level learning and to evaluate student perceptions of questioning. Twenty-three dental hygiene students participated in two control lectures using traditional lecturing methods. The students served as their own controls by next participating in two experimental lectures with questions asked throughout the lecture at both low and high cognitive levels. Student performance was measured with an examination containing low- and high-level questions. The interaction between the group and the level of questions was analyzed using ANOVA, and no statistically significant difference was found. Based on a Likert scale (1 to 6), average ratings for student perceptions were as follows: enjoyment of use, 4.5; understanding the lecture material, 4.74; and questioning effectiveness, 4.35. Student perceptions of questioning were positive; however, this strategy was found to be no more effective than the traditional lecture in promoting retention of information.

To examine the correlation between students accessing recorded lecture files (audio and slides) online and course grades and class attendance. Second professional year (of 6-year program) students in a therapeutics course had access to recorded online lectures for 72 hours following live lectures. The number and duration of lecture accessions were compared to final course grades and class attendance. Course grades were compared to those of a historical control group. At the end of the semester, students completed a brief survey instrument regarding their use and perceptions of online lectures. No correlation was found between final course grades and the number of lecture accessions (r = 0.0014) or total number of minutes lectures were viewed (r = 0.033), nor between class attendance and minutes viewed (r = 0.2158). Students with access to recorded lectures outperformed the historical control group on the final examination (p students reported no influence of online files on class attendance. Posting lectures online did not affect student outcomes, but students did score higher on the final examination.

A marriage of continuance: professional development for mathematics lecturers

Barton, Bill; Oates, Greg; Paterson, Judy; Thomas, Mike

2015-06-01

In a 2-year project, we developed and trialled a mode of lecturing professional development amongst staff in our department of mathematics. Theoretically grounded in Schoenfeld's resources, orientations, and goals (ROG) model of teacher action, a group met regularly to discuss both the video excerpts of themselves lecturing along with written pre- and post-lecture statements of their "ROGs". We found evidence of improved teaching performance but more interestingly, identified key aspects of our practice and of undergraduate mathematics that received repeated attention and developed further theoretical insight into lecturer behaviour in mathematics. The trial has been successful enough to be expanded into further groups that now constitute a professional development culture within our department.

A syndrome of multiorgan hyperplasia with features of gigantism, tumorigenesis, and female sterility in p27(Kip1)-deficient mice.

Targeted disruption of the murine p27(Kip1) gene caused a gene dose-dependent increase in animal size without other gross morphologic abnormalities. All tissues were enlarged and contained more cells, although endocrine abnormalities were not evident. Thymic hyperplasia was associated with increased T lymphocyte proliferation, and T cells showed enhanced IL-2 responsiveness in vitro. Thus, p27 deficiency may cause a cell-autonomous defect resulting in enhanced proliferation in response to mitogens. In the spleen, the absence of p27 selectively enhanced proliferation of hematopoietic progenitor cells. p27 deletion, like deletion of the Rb gene, uniquely caused neoplastic growth of the pituitary pars intermedia, suggesting that p27 and Rb function in the same regulatory pathway. The absence of p27 also caused an ovulatory defect and female sterility. Maturation of secondary ovarian follicles into corpora lutea, which express high levels of p27, was markedly impaired.

Lectures are traditionally used for teaching declarative knowledge. One established tool for clinical education is the demonstration of a real patient. The use of real patients in the daily clinical environment is increasingly difficult. The use of a virtual patient simulator (VPS) can potentially circumvent these problems. Unlimited availability and the opportunity of an electronic feedback system could possibly enrich traditional lectures by enabling more interactivity that meets the expectations of the current student generation. As students face the consequences of their own decisions they take a more active role in the lecture. VPS links declarative knowledge with visual perception that is known to influence students' motivation. Until now, there have been no reports covering the usage and validation of interactive VPS for supporting traditional lectures. In this study, we (1) described the development of a custom-made three-dimensional (3D) VPS for supporting the traditional lecture and (2) performed a feasibility study including an initial assessment of this novel educational concept. Conceptualization included definition of curricular content, technical realization and validation. A custom-made simulator was validated with 68 students. The degree of student acceptance was evaluated. Furthermore, the effect on knowledge gain was determined by testing prelecture and postlecture performance. A custom-made simulator prototype that displays a 3D virtual clinic environment was developed and linked to a PowerPoint presentation. Students were able to connect to the simulator via electronic devices (smartphones and tablets) and to control the simulator via majority vote. The simulator was used in 6 lectures and validated in 2 lectures with 68 students each. Student acceptance and their opinion about effectiveness and applicability were determined. Students showed a high level of motivation when using the simulator as most of them had fun using it. Effect on

All important subjects of radiation protection are presented in concise form; the explanations may serve as lecture manuscripts. The lectures are divided into 16 to 19 teaching units. Each teaching unit is supplemented by a slide to be projected on a screen while the text is read. This method of visual teaching has already been tried with good results in medicine and medical engineering. Pictures of the slides are given in the text so that the book may also be used for self-studies. The main facts are summarized at the end of each lesson. The finished book will consist of 8 lessons; the first three of these discuss 1. Radiation effects and hazards 2. Dose definitions and units and their role in radiology and radiation protection 3. Dose limits and legal specifications. (orig.) [de

2017-01-01

In recent years, medical schools have provided students access to video recordings of course lectures, but few studies have investigated the impact of this on ratings of courses and teachers. This study investigated whether the method of viewing lectures was related to student ratings of the course and its components and whether the method used changed over time. Preclinical medical students indicated whether ratings of course lectures were based primarily on lecture attendance, video capture, or both. Students were categorized into Lecture, Video, or Both groups based on their responses to this question. The data consisted of 7584 student evaluations collected over 2 years. Students who attended live lectures rated the course and its components higher than students who only viewed the video or used both methods, although these differences were very small. Students increasingly watched lectures exclusively by video over time: in comparison with first-year students, second-year students were more likely to watch lectures exclusively by video; in comparison with students in the first half of the academic year, students in the second half of the academic year were more likely to watch lectures exclusively by video. With the increase in use of lecture video recordings across medical schools, attention must be paid to student attitudes regarding these methods.

The Feynman lectures on physics

International Nuclear Information System (INIS)

Feynman, R.P.

1979-01-01

This set of lectures tries to elucidate from the beginning those features of the quantum mechanics which are most general. The first lectures tackle head on the ideas of a probability amplitude, the interference of amplitudes, the abstract notion of a state, and the superposition and resolution of states - and the Dirac notation is used from the start. In each instance the ideas are introduced together with a detailed discussion of some specific examples - to try to make the physical ideas as real as possible. The time dependence of states including states of definite energy comes next, and the ideas are applied at once to the study of two-state systems. A detailed discussion of the ammonia maser provides the framework for the introduction to radiation absorption and induced transitions. The lectures then go on to consider more complex systems, leading to a discussion of the propagation of electrons in a crystal, and to a rather complete treatment of the quantum mechanics of angular momentum. Our introduction to quantum mechanics ends in Chapter 20 with a discussion of the Schroedinger wave function, its differential equation, and the solution for the hydrogen atom. The last Chapter of this volume is not intended to be a part of the 'course.' It is a 'seminar' on superconductivity and was given in the spirit of some of the entertainment lectures of the first two volumes, with the intent of opening to the students a broader view of the relation of what they were learning to the general culture of physics. Feynman's 'epilogue' serves as the period to the three-volume series [fr

Optoelectronic lessons as an interdisciplinary lecture

Science.gov (United States)

Wu, Dan; Wu, Maocheng; Gu, Jihua

2017-08-01

It is noticed that more and more students in college are passionately curious about the optoelectronic technology, since optoelectronic technology has advanced extremely quickly during the last five years and its applications could be found in a lot of domains. The students who are interested in this area may have different educational backgrounds and their majors cover science, engineering, literature and social science, etc. Our course "History of the Optoelectronic Technology" is set up as an interdisciplinary lecture of the "liberal education" at our university, and is available for all students with different academic backgrounds from any departments of our university. The main purpose of the course is to show the interesting and colorful historical aspects of the development of this technology, so that the students from different departments could absorb the academic nourishment they wanted. There are little complex derivations of physical formulas through the whole lecture, but there are still some difficulties about the lecture which is discussed in this paper.

Sir Robert Ball: Victorian Astronomer and Lecturer par excellence

Science.gov (United States)

Jones, R. I. G.

2005-12-01

Between 1875 and 1910 Sir Robert Stawell Ball gave an estimated 2,500 lectures in towns and cities all over the British Isles and abroad. This paper traces his lecturing career from its beginnings in Ireland to the triumphs of the Royal Institution, and on lecture tours in the United States of America. After a period in mathematics and mechanics, he became a populariser of science, especially astronomy, and found fame and fortune among the working classes and the aristocracy. What motivated him to tireless travels is uncertain, but it might have been that it was rewarding, financially and to his reputation. Whatever his motives, contemporary accounts are clear that BallÕs lectures were extremely popular and well-received.

Maintaining Students’ Involvement in a Math Lecture Using Countdown Timers

Directory of Open Access Journals (Sweden)

Ann Krizzel A. Aban

2015-12-01

Full Text Available Involving students in a lecture is an important but not an easy task that every lecturer must encourage. This task becomes even greater in a math class that is composed of eighty to a hundred sixty students. In 2007, the University of the Philippines Los Baños (UPLB started offering some of its basic math courses in lecture-recitation set-up. This shift and many other factors drove most math instructors of UPLB to widely use presentation software, such as the PowerPoint (PPT, to deliver their lectures. The non-stop use of these softwares, however, seems to have negative effects on the students when it comes to maintaining their involvement in a lecture discussion for they tend to be more passive spectators. On the other hand, adding countdown timers strategically on some parts of the discussion seems to lessen such negative effects. This study determined the effectiveness of using countdown timers in maintaining students’ involvement in a lecture of MATH 27 (Analytic Geometry and Calculus II, a course in UPLB commonly taken by sophomore students. Results show that the effectiveness of countdown timers, as perceived by the students, is independent to students’ genders and degree programs, but is dependent to the colleges where the students belong to. Also, some effects of countdown timers are significantly correlated to various data from students’ profiles. It was concluded in the study that the use of countdown timers is effective in maintaining student’s involvement in MATH 27 lectures and might also be useful in other math lecture classes

Lectures on the mathematics of quantum mechanics I

CERN Document Server

Dell'Antonio, Gianfausto

2015-01-01

The first volume (General Theory) differs from most textbooks as it emphasizes the mathematical structure and mathematical rigor, while being adapted to the teaching the first semester of an advanced course in Quantum Mechanics (the content of the book are the lectures of courses actually delivered.). It differs also from the very few texts in Quantum Mechanics that give emphasis to the mathematical aspects because this book, being written as Lecture Notes, has the structure of lectures delivered in a course, namely introduction of the problem, outline of the relevant points, mathematical tools needed, theorems, proofs. This makes this book particularly useful for self-study and for instructors in the preparation of a second course in Quantum Mechanics (after a first basic course). With some minor additions it can be used also as a basis of a first course in Quantum Mechanics for students in mathematics curricula. The second part (Selected Topics) are lecture notes of a more advanced course aimed at giving th...

Digital Earth visualization technologies, from ArcGIS to Google Earth, have allowed for the integration of complex, disparate data sets to produce visually rich and compelling three-dimensional models of sub-surface and surface resource distribution patterns. The rendering of these models allows the public to quickly understand complicated geospatial relationships that would otherwise take much longer to explain using traditional media. At the Denver Museum of Nature & Science (DMNS), we have used such visualization technologies, including real-time virtual reality software running in the immersive digital "fulldome" Gates Planetarium, to impact the community through topical policy presentations. DMNS public lectures have covered regional issues like water resources, as well as global topics such as earthquakes, tsunamis, and resource depletion. The Gates Planetarium allows an audience to have an immersive experience-similar to virtual reality "CAVE" environments found in academia-that would otherwise not be available to the general public. Public lectures in the dome allow audiences of over 100 people to comprehend dynamically changing geospatial datasets in an exciting and engaging fashion. Surveys and interviews show that these talks are effective in heightening visitor interest in the subjects weeks or months after the presentation. Many visitors take additional steps to learn more, while one was so inspired that she actively worked to bring the same programming to her children's school. These preliminary findings suggest that fulldome real-time visualizations can have a substantial long-term impact on an audience's engagement and interest in science topics.

Mathematical omnibus thirty lectures on classic mathematics

CERN Document Server

Fuchs, Dmitry; Fuchs, Dmitry

2007-01-01

The book consists of thirty lectures on diverse topics, covering much of the mathematical landscape rather than focusing on one area. The reader will learn numerous results that often belong to neither the standard undergraduate nor graduate curriculum and will discover connections between classical and contemporary ideas in algebra, combinatorics, geometry, and topology. The reader's effort will be rewarded in seeing the harmony of each subject. The common thread in the selected subjects is their illustration of the unity and beauty of mathematics. Most lectures contain exercises, and solutions or answers are given to selected exercises. A special feature of the book is an abundance of drawings (more than four hundred), artwork by an accomplished artist, and about a hundred portraits of mathematicians. Almost every lecture contains surprises for even the seasoned researcher.

T ahmine Razi

2013-05-01

Full Text Available Introduction: One of the main problems in learning extraoral radiographic anatomic indexes is the long interval between presentation of radiology and human anatomy courses, resulting in forgetting anatomic regions. Therefore, radiographic indexes are formed as complete abstract and transient images in students’ minds; as a result, their learning and retention decrease. The aim of this study was to compare lecture with combination of computer-assisted learning and lecture of extra-oral radiographic landmarks among dental students. Methods: This interventional study was carried out in 2009 on 51 dental students of Tabriz University of Medical Sciences. Students were randomly allocated into two groups. The first group was taught through a teaching method which involved lectures in the classroom. In the second group, a CD was given to the students. The teaching was accomplished through presentation using skull. Six months after finishing the teaching, both groups took a similar test for evaluation of long term learning. The data was analyzed by SPSS 16 using U Mann-Whitney test. Results: There was no significant differences in the mean scores between the two groups in the first exam after teaching (P=0.13, yet it was significant in the second exam (regarding retention (P=0.006, and average of non-traditional teaching method group (20.89±10.23 was higher than that of lecture group (13.48±6.39. Conclusion: Based on the results, non-traditional technique of teaching was not more effective than the lecture in short-term learning but in longterm learning, non-traditional technique was more effective than the lecture.

2010-10-01

To compare eclampsia and magnesium toxicity management among residents randomly assigned to lecture or simulation-based education. Statified by year, residents (n = 38) were randomly assigned to 3 educational intervention groups: Simulation→Lecture, Simulation, and Lecture. Postintervention simulations were performed for all and scored using standardized lists. Maternal, fetal, eclampsia management, and magnesium toxcity scores were assigned. Mann-Whitney U, Wilcoxon rank sum and χ(2) tests were used for analysis. Postintervention maternal (16 and 15 vs 12; P < .05) and eclampsia (19 vs 16; P < .05) scores were significantly better in simulation based compared with lecture groups. Postintervention magnesium toxcitiy and fetal scores were not different among groups. Lecture added to simulation did not lead to incremental benefit when eclampsia scores were compared between Simulation→Lecture and Simulation (19 vs 19; P = nonsignificant). Simulation training is superior to traditional lecture alone for teaching crucial skills for the optimal management of both eclampsia and magnesium toxicity, 2 life-threatening obstetric emergencies.

Full Text Available The lecture has been much maligned as a pedagogical form. It has been denigrated as a «hot ‎medium» that has long been «superseded» by the cooler dialogical and televisual forms. Yet the lecture ‎persists and even flourishes today in the form of the podcast, the TED Talk, Kahn Academy and the «smart» ‎lecture hall (outfitted with audio, video and student feedback technologies. This persistence ‎should lead us to re-evaluate both the lecture and the role of the media that have been related to it over time. This paper examines the lecture as a site of intersecting media, as «a site where differences between media are negotiated» as these media ‎evolve (Franzel 2010. This study shows the lecture as bridging oral ‎communication with writing and newer media technologies, rather than as being superseded ‎by newer electronic and digital forms. The result is a remarkably adaptable and robust form ‎that combines textual record and ephemeral event. It is that is capable of addressing a range of ‎different demands and circumstances, both in terms of classroom pragmatics and more abstractly, of the circulation of knowledge itself. The Web, which ‎brings multiple media together with new and established forms and genres, presents fertile ‎grounds for the continuation and revitalization of the lecture as a dominant pedagogical form.

2001-01-01

These lectures concentrate on evolution and generation of dark matter perturbations. The purpose of the lectures is to present, in a systematic way, a comprehensive review of the cosmological parameters that can lead to observable effects in the dark matter clustering properties. We begin by reviewing the relativistic linear perturbation theory formalism. We discuss the gauge issue and derive Einstein's and continuity equations for several popular gauge choices. We continue by developing fluid equations for cold dark matter and baryons and Boltzmann equations for photons, massive and massless neutrinos. We then discuss the generation of initial perturbations by the process of inflation and the parameters of that process that can be extracted from the observations. Finally we discuss evolution of perturbations in various regimes and the imprint of the evolution on the dark matter power spectrum both in the linear and in the nonlinear regime. (author)

PDF Lecture Materials for Online and ``Flipped'' Format Astronomy Courses

Science.gov (United States)

Kary, D. M.; Eisberg, J.

2013-04-01

Online astronomy courses typically rely on students reading the textbook and/or a set of text-based lecture notes to replace the “lecture” material. However, many of our students report that this is much less engaging than in-person lectures, especially given the amount of interactive work such as “think-pair-share” problems done in many astronomy classes. Students have similarly criticized direct lecture-capture. To address this, we have developed a set of PowerPoint-style presentations with embedded lecture audio combined with prompts for student interaction including think-pair-share questions. These are formatted PDF packages that can be used on a range of different computers using free software. The presentations are first developed using Microsoft PowerPoint software. Audio recordings of scripted lectures are then synchronized with the presentations and the entire package is converted to PDF using Adobe Presenter. This approach combines the ease of editing that PowerPoint provides along with the platform-independence of PDF. It's easy to add, remove, or edit individual slides as needed, and PowerPoint supports internal links so that think-pair-share questions can be inserted with links to feedback based on the answers selected. Modern PDF files support animated visuals with synchronized audio and they can be read using widely available free software. Using these files students in an online course can get many of the benefits of seeing and hearing the course material presented in an in-person lecture format. Students needing extra help in traditional lecture classes can use these presentations to help review the materials covered in lecture. Finally, the presentations can be used in a “flipped” format in which students work through the presentations outside of class time while spending the “lecture” time on in-class interaction.

Effect of lecture instruction on student performance on qualitative questions

Science.gov (United States)

Heron, Paula R. L.

2015-06-01

The impact of lecture instruction on student conceptual understanding in physics has been the subject of research for several decades. Most studies have reported disappointingly small improvements in student performance on conceptual questions despite direct instruction on the relevant topics. These results have spurred a number of attempts to improve learning in physics courses through new curricula and instructional techniques. This paper contributes to the research base through a retrospective analysis of 20 randomly selected qualitative questions on topics in kinematics, dynamics, electrostatics, waves, and physical optics that have been given in introductory calculus-based physics at the University of Washington over a period of 15 years. In some classes, questions were administered after relevant lecture instruction had been completed; in others, it had yet to begin. Simple statistical tests indicate that the average performance of the "after lecture" classes was significantly better than that of the "before lecture" classes for 11 questions, significantly worse for two questions, and indistinguishable for the remaining seven. However, the classes had not been randomly assigned to be tested before or after lecture instruction. Multiple linear regression was therefore conducted with variables (such as class size) that could plausibly lead to systematic differences in performance and thus obscure (or artificially enhance) the effect of lecture instruction. The regression models support the results of the simple tests for all but four questions. In those cases, the effect of lecture instruction was reduced to a nonsignificant level, or increased to a significant, negative level when other variables were considered. Thus the results provide robust evidence that instruction in lecture can increase student ability to give correct answers to conceptual questions but does not necessarily do so; in some cases it can even lead to a decrease.

Woo, M A; Kimmick, J V

2000-01-01

Although many higher education programs are using the Internet to teach classes, there are few published reports on the effectiveness of this method on test scores or student satisfaction. The purpose of this study was to compare test and student satisfaction scores of graduate nursing students who take a nursing research course via the Internet with those of students who take the same course via traditional lecture instruction. In addition, student technical support use and Internet student lecture attendance also were examined. A total of 97 students (Internet, 44; lectures, 53) participated. There were no significant differences in test scores and overall course student satisfaction (P > .05). However, the Internet students reported significantly higher (P = .04) stimulation of learning compared with the traditional lecture students. Technical support use by the Internet students was high initially and was related to software problems. Of interest were the large proportion of Internet students (73 percent) who attended at least 3 of the 10 lectures. Use of the Internet to teach graduate-level nursing research can provide comparable learning and student satisfaction to traditional lecture instructional methods.

Effects of three types of lecture notes on medical student achievement.

Science.gov (United States)

Russell, I J; Caris, T N; Harris, G D; Hendricson, W D

1983-08-01

Two parallel studies were conducted with junior medical students to determine what influence the forms of lecture notes would have on learning. The three types of notes given to the students were: a comprehensive manuscript of the lecture containing text, tables, and figures; a partial handout which included some illustrations but required substantial annotation by the students; and a skeleton outline containing no data from the lecture. The students' knowledge about the subject was measured before the lecture, immediately after the lecture, two to four weeks later, and approximately three months later. The students' responses to questionnaires indicated a strong preference for very detained handouts as essential to preparation for examinations. By contract, the students' performances on tests generally were better for those who had received the partial or skeleton handout formats. This was particularly true for information presented during the last quarter of each lecture, when learning efficiency of the skeleton handout group increased while the other two handout groups exhibited learning fatigue. It was concluded that learning by medical students was improved when they recorded notes in class.

The interrupted learner: How distractions during live and video lectures influence learning outcomes.

Science.gov (United States)

Zureick, Andrew H; Burk-Rafel, Jesse; Purkiss, Joel A; Hortsch, Michael

2017-11-27

New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi-year study of the first-year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated. Here, three cohorts of first-year medical students (N = 439 respondents, 86.6% response rate) were surveyed in greater detail regarding lecture attendance and video usage, focusing on study behaviors that may influence histology learning outcomes. Students who reported always attending lectures or viewing lecture videos had higher average histology scores than students who employed an inconsistent strategy (i.e., mixing live attendance and video lectures). Several behaviors were negatively associated with histology performance. Students who engaged in "non-lecture activities" (e.g., social media use), students who reported being interrupted while watching the lecture video, or feeling sleepy/losing focus had lower scores than their counterparts not engaging in these behaviors. This study suggests that interruptions and distractions during medical learning activities-whether live or recorded-can have an important impact on learning outcomes.

Trends in National Emergency Medicine Conference Didactic Lectures Over a 6-Year Period.

Gottlieb, Michael; Riddell, Jeff; Njie, Abdoulie

2017-01-01

National conference didactic lectures have traditionally featured hour-long lecture-based presentations. However, there is evidence that longer lectures can lead to both decreased attention and retention of information. The authors sought to identify trends in lecture duration, lecture types, and number of speakers at four national emergency medicine (EM) conferences over a 6-year period. The authors performed a retrospective analysis of the length, number of speakers, and format of didactic lectures at four different national EM conferences over 6 years. The authors abstracted data from the national academic assemblies for the four largest not-for-profit EM organizations in the United States: American Academy of Emergency Medicine, American College of Emergency Physicians, Council of Emergency Medicine Residency Directors, and Society for Academic Emergency Medicine. There was a significant yearly decrease in the mean lecture lengths for three of the four conferences. There was an increase in the percentage of rapid fire sessions over the preceding 2 years with a corresponding decrease in the percentage of general educational sessions. There was no significant difference in the mean number of speakers per lecture. An analysis of 4210 didactic lecture sessions from the annual meetings of four national EM organizations over a 6-year period showed significant decreases in mean lecture length. These findings can help to guide EM continuing medical education conference planning and research.

Lectures on Quantum Gravity

2006-01-01

The 2002 Pan-American Advanced Studies Institute School on Quantum Gravity was held at the Centro de Estudios Cientificos (CECS),Valdivia, Chile, January 4-14, 2002. The school featured lectures by ten speakers, and was attended by nearly 70 students from over 14 countries. A primary goal was to foster interaction and communication between participants from different cultures, both in the layman’s sense of the term and in terms of approaches to quantum gravity. We hope that the links formed by students and the school will persist throughout their professional lives, continuing to promote interaction and the essential exchange of ideas that drives research forward. This volume contains improved and updated versions of the lectures given at the School. It has been prepared both as a reminder for the participants, and so that these pedagogical introductions can be made available to others who were unable to attend. We expect them to serve students of all ages well.

The Stanley Melville Memorial Lectures 1937-1945

2006-01-01

The Archibald Reid Memorial Competition theses have been precised in a previous edition of Radiography (Vol 11 Issue 3 Aug 2005). A great deal of information about the development of the profession and techniques was highlighted. In this edition (Vol 12 Issue 1 February 2006) we have looked at the Stanley Melville Memorial Lectures from 1937 to 1945. Unfortunately the First lecture, which took place in 1937, was not published. Eminent speakers, radiologists, radiographers, physicists and industrialists presented papers based on the background of radiography or radiotherapy of that period. There was obviously no point in reprinting the full lecture/paper but in selecting interesting information, quotations and ideas it was hoped to stimulate further reading and to continue the database. The exercise was also undertaken to show the progress made from the beginning to the present day procedures and practice. It will be seen that some of the concepts we hold today were in fact outlined 50 or 60 years ago. The other important thing to note is how the enthusiasm and foresight which people like Stanley Melville exhibited, has brought radiology and radiography, and radiologists and radiographers to the present. Seven of the Melville lectures appear in this paper and those delivered between 1946 and 1950 will form the basis of the next paper in the series

Full Text Available considerable progress in developing public administration teaching. However the need to increase student interest and involvement in the learning process is a largely widespread issue in all Romanian universities, which impacts on both teaching/learning methodology and student assessment methods. The present study aims to analyze (1 teaching practices, (2 students’ preferences and perceptions regarding these practices, and (3 the relationship between these preferences and real practices. I focused on teaching of public administration (or administrative sciences as a discipline and the possible variations in students’ preferences as opposed to teachers’ beliefs and real practices. Moreover, I was concerned with educational effectiveness in terms of acquired competencies and aspects that could increase the effectiveness of students’ learning. In respect of these objectives I designed two questionnaires: one for students in public administration enrolled in undergraduate programs and another for the teaching staff. The two questionnaires addressed comparable research questions. Some questions were similar in order to allow the comparison of responses for both categories of respondents. Seven public universities were selected through a convenience sampling method from more than 32 Romanian universities which have developed accredited public administration programs. I have chosen the seven most important programs according to student numbers, from all geographic areas of the country. The last part shows that the three hypotheses were not fully validated and for a further research, I should investigate the problem of poor results of my students by a qualitative research among the students with poor attendance and lower thanaverage academic performance.

Dudley Wright in 1984, is to bring recent progress in science to the attention of the general public. Each Colloquium consists of a series of lectures given by eminent scientists, this year including two Nobel Prize Winners, all of which are open to the general public. The 2000 series of Colloquium lectures is entitled “Time, Matter, Energy : from stars to our genes”, three familiar notions which nevertheless remain intangible for us. This series of five lectures will examine these notions in original ways. Thus the notion of time will be viewed from the perspective of the astronomer who, with the aid of telescopes, is able to go back in time and watch time expanding with the universe.

Material and Methods: The present study was conducted in the well-equipped lecture theater of Dhanalakshmi Srinivasan Medical College and Hospital (DSMCH, Tamil Nadu. A fully prepared interactive lecture on the specific topic was delivered by using power point presentation for second year MBBS students. Before start to deliver the lecture, instructor distributed multiple choice 10 questionnaires to attempt within 10 minutes. After 30 minutes of delivering lecture, again instructor distributed same 10 sets of multiple choice questionnaires to attempt in 10 minutes. The topic was never disclosed to the students before to deliver the lecture. Statistics: We analyzed the pre-lecture & post-lecture questions of each student by applying the paired t-test formula by using www.openepi.com version 3.01 online/offline software and by using Microsoft Excel Sheet Windows 2010. Results: The 31 male, 80 female including 111 students of average age 18.58 years baseline (pre-lecture receptivity mean % was 30.99 ± 14.64 and post-lecture receptivity mean % was increased upto 53.51± 19.52. The only 12 students out of 111 post-lecture receptivity values was less (mean % 25.8± 10.84 than the baseline (mean % 45± 9.05 receptive value and this reduction of receptivity was more towards negative side. Conclusion: In interactive lecture session with power point presentation students/learners can learn, even in large-class environments, but it should be active-learner centered.

Using Online Lectures to Make Time for Active Learning

Science.gov (United States)

Prunuske, Amy J.; Batzli, Janet; Howell, Evelyn; Miller, Sarah

2012-01-01

To make time in class for group activities devoted to critical thinking, we integrated a series of short online lectures into the homework assignments of a large, introductory biology course at a research university. The majority of students viewed the online lectures before coming to class and reported that the online lectures helped them to complete the in-class activity and did not increase the amount of time they devoted to the course. In addition, students who viewed the online lecture performed better on clicker questions designed to test lower-order cognitive skills. The in-class activities then gave the students practice analyzing the information in groups and provided the instructor with feedback about the students’ understanding of the material. On the basis of the results of this study, we support creating hybrid course models that allow students to learn the fundamental information outside of class time, thereby creating time during the class period to be dedicated toward the conceptual understanding of the material.

CERN. Geneva

2018-01-01

Algorithms have existed, in one form or another, for as long as humanity has. During the second half of the 20th century, the field was revolutionised with the introduction of ever faster computers. In these lectures we discuss how algorithms are designed, how to evaluate their speed, and how to identify areas of improvement in existing algorithms. An algorithm consists of more than just a series of instructions; almost as important is the memory structure of the data on which it operates. A part of the lectures will be dedicated to a discussion of the various ways one can store data in memory, and their advantages and disadvantages.

Introductory lectures on conformal field theory and strings

International Nuclear Information System (INIS)

Randjbar-Daemi, S.; Strathdee, J.

1990-01-01

The aim of these lectures is to provide an introduction to a first quantized formulation of string theory. This amounts to developing a consistent set of prescriptions for the perturbative computation of on-shell string amplitudes. The principal tool in this development is 2-dimensional conformal field theory on oriented manifolds of finite genus without boundaries (we treat only closed strings). This class of theory is much simpler than 4-dimensional quantum gravity with which it has many similarities. The geometry is not dynamical in this case, and the matter fields are not sensitive to local features of the geometry but only to global properties which can be characterized by a finite set of parameters (moduli). This can be formulated as field theory on a Riemann surface. We specialize mainly to free field theories for which the quantization problem can be completely solved by elementary means. An introduction to the general case will be given in Lectures II and III where the algebraic approach is discussed. The mathematics of Riemann surfaces is a well developed subject whose formalism is reviewed along with some of the principal theorems in Lecture IV. Physical string states are realized in the Hilbert space of a conformal field theory by the action of so-called ''vertex operators'' on the field theory vacuum state. Correlation functions of these vertex operators serve as ingredients for the computation of string amplitudes. They are to be integrated so as to include the contributions of all conformally inequivalent geometries, and a further manipulation (the GSO projection) is to be performed. These steps are to be regarded as part of the string prescription. The are introduced ad hoc to meet invariance and unitarity requirements. However, in these introductory lectures we give a description only of the integration over geometries (Lecture VII). The GSO projection, and related questions of modular invariance and unitarity are beyond the scope of these lectures

Monte Carlo Techniques for Nuclear Systems - Theory Lectures

International Nuclear Information System (INIS)

Brown, Forrest B.; Univ. of New Mexico, Albuquerque, NM

2016-01-01

These are lecture notes for a Monte Carlo class given at the University of New Mexico. The following topics are covered: course information; nuclear eng. review & MC; random numbers and sampling; computational geometry; collision physics; tallies and statistics; eigenvalue calculations I; eigenvalue calculations II; eigenvalue calculations III; variance reduction; parallel Monte Carlo; parameter studies; fission matrix and higher eigenmodes; doppler broadening; Monte Carlo depletion; HTGR modeling; coupled MC and T/H calculations; fission energy deposition. Solving particle transport problems with the Monte Carlo method is simple - just simulate the particle behavior. The devil is in the details, however. These lectures provide a balanced approach to the theory and practice of Monte Carlo simulation codes. The first lectures provide an overview of Monte Carlo simulation methods, covering the transport equation, random sampling, computational geometry, collision physics, and statistics. The next lectures focus on the state-of-the-art in Monte Carlo criticality simulations, covering the theory of eigenvalue calculations, convergence analysis, dominance ratio calculations, bias in Keff and tallies, bias in uncertainties, a case study of a realistic calculation, and Wielandt acceleration techniques. The remaining lectures cover advanced topics, including HTGR modeling and stochastic geometry, temperature dependence, fission energy deposition, depletion calculations, parallel calculations, and parameter studies. This portion of the class focuses on using MCNP to perform criticality calculations for reactor physics and criticality safety applications. It is an intermediate level class, intended for those with at least some familiarity with MCNP. Class examples provide hands-on experience at running the code, plotting both geometry and results, and understanding the code output. The class includes lectures & hands-on computer use for a variety of Monte Carlo calculations

The effect of podcast lectures on nursing students' knowledge retention and application.

Science.gov (United States)

Abate, Karen S

2013-01-01

This pilot study sought to evaluate the effectiveness of academic podcasts in promoting knowledge retention and application in nursing students. Nursing education no longer simply occurs in a fixed location or time. Computer-enhanced mobile learning technologies, such as academic podcasts, must be grounded in pedagogically sound characteristics to ensure effective implementation and learning in nursing education. A convenience sample of 35 female undergraduate nursing students was randomized into three groups: a traditional face-to-face lecture group, an unsegmented (non-stop) podcast lecture group, and a segmented podcast lecture group. Retention and application of information were measured through a multiple-choice quiz and a case study based on lecture content. Students in the segmented podcast lecture group demonstrated higher scores on multiple-choice and case-study assessments than those in the other two groups. Nurse educators should be aware of this finding when seeking to employ podcast lectures in nursing education.

Kassab, Salah Eldin; Hassan, Nahla; Abu-Hijleh, Marwan F; Sequeira, Reginald P

2016-01-01

Recruitment of tutors to work in problem-based learning (PBL) programs is challenging, especially in that most of them are graduated from discipline-based programs. Therefore, this study aims at examining whether lecturing skills of faculty could predict their PBL tutoring skills. This study included evaluation of faculty (n=69) who participated in both tutoring and lecturing within particular PBL units at the College of Medicine and Medical Sciences (CMMS), Arabian Gulf University, Bahrain. Each faculty was evaluated by medical students (n=45±8 for lecturing and 8±2 for PBL tutoring) using structured evaluation forms based on a Likert-type scale (poor to excellent). The prediction of tutoring skills using lecturing skills was statistically analyzed using stepwise linear regression. Among the parameters used to judge lecturing skills, the most important predictor for tutoring skills was subject matter mastery in the lecture by explaining difficult concepts and responding effectively to students' questions. Subject matter mastery in the lecture positively predicted five tutoring skills and accounted for 25% of the variance in overall effectiveness of the PBL tutors (F=22.39, P=0.000). Other important predictors for tutoring skills were providing a relaxed class atmosphere and effective use of audiovisual aids in the lecture. Predicting the tutoring skills based on lecturing skills could have implications for recruiting tutors in PBL medical programs and for tutor training initiatives.

This research project was part of a planned initiative at the University of Pittsburgh School of Dental Medicine to incorporate lecture recordings as standard educational support technologies. The goal of an institutional survey was 1) to gather current data about how dental educators across the United States and Canada use lecture recordings; 2) determine dental educators' perceived value and outcomes of using lecture recordings; and 3) develop recommendations based on #1 and #2 for the dental education community. Of the sixty-six North American dental schools at the time of the study, forty-five schools responded to the survey, for a 68 percent response rate. Of the respondents, twenty-eight schools were found to currently conduct lecture recording; these comprised the study sample. This study focused on the dental schools' past experiences with lecture recording; thus, those not currently engaged in lecture recording were excluded from further analysis. The survey questions covered a wide range of topics, such as the scope of the lecture recording, logistics, instructional design considerations, outcomes related to student learning, evaluation and reception, barriers to lecture recording, and issues related to copyright and intellectual property. The literature review and results from the survey showed that no common guidelines for best practice were available regarding lecture recordings in dental education. The article concludes with some preliminary recommendations based on this study.

Blended learning, a new approach in educational planning, is defined as an applying more than one method, strategy, technique or media in education. Todays, due to the development of infrastructure of Internet networks and the access of most of the students, the Internet can be utilized along with traditional and conventional methods of training. The aim of this study was to compare the students' learning and satisfaction in combination of lecture and e-learning with conventional lecture methods. This quasi-experimental study is conducted among the sophomore students of Public Health School, Tehran University of Medical Science in 2012-2013. Four classes of the school are randomly selected and are divided into two groups. Education in two classes (45 students) was in the form of lecture method and in the other two classes (48 students) was blended method with e-Learning and lecture methods. The students' knowledge about tuberculosis in two groups was collected and measured by using pre and post-test. This step has been done by sending self-reported electronic questionnaires to the students' email addresses through Google Document software. At the end of educational programs, students' satisfaction and comments about two methods were also collected by questionnaires. Statistical tests such as descriptive methods, paired t-test, independent t-test and ANOVA were done through the SPSS 14 software, and p≤0.05 was considered as significant difference. The mean scores of the lecture and blended groups were 13.18±1.37 and 13.35±1.36, respectively; the difference between the pre-test scores of the two groups was not statistically significant (p=0.535). Knowledge scores increased in both groups after training, and the mean and standard deviation of knowledge scores of the lectures and combined groups were 16.51±0.69 and 16.18±1.06, respectively. The difference between the post-test scores of the two groups was not statistically significant (p=0.112). Students

2016-11-01

Full Text Available Soft skills, especially communication skills, are important skills which each graduate must possess. Accordingly, several courses and approaches have been carried out in universities to train students in communication skills. The skills are normally evaluated by course lecturers. However, assessments by a third party from outside the university are valuable so that the students’ ahievements may be weighed against external evaluators’ point of views. In the Department of Electrical, Electronic and Systems Engineering (DEESE, Universiti Kebangsaan Malaysia (UKM, communication skills assessment by external lecturers and industry representatives are performed on Hari Poster JKEES, where students present their final year project poster. There are two categories of evaluation, namely project and communication skills. The project evaluation covers content, result and impact, while communication skills evaluation covers poster layout and design, and delivery. This study only analyse the students’ communication skills achievement. The participants of this study consists of 109 final year students from two batches, of which 51 students are from year 2014 and the other 58 students from year 2015. The results show that for the year 2014 students, the mean mark given by external lecturers in layout and design category is 6.7, while the mean mark from industry evaluators is 6.5. For the 2015 batch, the mean mark in the layout and design category is 6.3 from external lecturers and 5.9 from industry evaluators. In the delivery category, the mean marks for the 2014 batch are 7.1 and 6.6 from external lecturers and industry evaluators, espectively. Meanwhile, for the 2015 batch, the mean marks by external lecturers and industry evaluators are 6.3 and 5.8, respectively. The results show that both external lecturers and industry representatives judged DEESE students’ communication skills to be good.

This invaluable monograph has arisen in part from E Witten's lectures on topological quantum field theory in the spring of 1989 at Princeton University. At that time Witten unified several important mathematical works in terms of quantum field theory, most notably the Donaldson polynomial, the Gromov-Floer homology and the Jones polynomials. In his lectures, among other things, Witten explained his intrinsic three-dimensional construction of Jones polynomials via Chern-Simons gauge theory. He provided both a rigorous proof of the geometric quantization of the Chern-Simons action and a very ill

2007-10-01

This study explored whether first-year medical students make deliberate decisions about attending nonrequired lectures. If so, it sought to identify factors that influence these decisions, specifically addressing the potential impact of electronic materials. Medical students who completed first-year studies between 2004 and 2006 responded to an open-ended survey question about their own lecture-attendance decisions. Responses were coded to capture major themes. Students' ratings of the electronic materials were also examined. Most respondents made deliberate attendance decisions. Decisions were influenced by previous experiences with the lecturer, predictions of what would occur during the session itself, personal learning preferences, and learning needs at that particular time, with the overriding goal of maximizing learning. Access to electronic materials did not influence students' choices. Fears that the increasing availability of technology-enhanced educational materials has a negative impact on lecture attendance seem unfounded.

A Comparison of Traditional and Engaging Lecture Methods in a Large, Professional-Level Course

Science.gov (United States)

Miller, Cynthia J.; McNear, Jacquee; Metz, Michael J.

2013-01-01

In engaging lectures, also referred to as broken or interactive lectures, students are given short periods of lecture followed by "breaks" that can consist of 1-min papers, problem sets, brainstorming sessions, or open discussion. While many studies have shown positive effects when engaging lectures are used in undergraduate settings,…

Just do it: flipped lecture, determinants and debate

Science.gov (United States)

Kensington-Miller, Barbara; Novak, Julia; Evans, Tanya

2016-08-01

This paper describes a case study of two pure mathematicians who flipped their lecture to teach matrix determinants in two large mathematics service courses (one at Stage I and the other at Stage II). The purpose of the study was to transform the passive lecture into an active learning opportunity and to introduce valuable mathematical skills, such as debate, argument and disagreement. The students were told in advance to use the online material to prepare, which had a short handout on matrix determinants posted, as the lesson would be interactive and would rely on them having studied this. At the beginning of the lesson, the two mathematicians worked together to model the skill of professional disagreement, one arguing for the cofactor expansion method and the other for the row reduction method. After voting for their preferred method, the students worked in small groups on examples to defend their choice. Each group elected a spokesperson and a political style debate followed as the students argued the pros and cons of each technique. Although one lecture does not establish whether the flipped lecture model is preferable for student instruction, the paper presents a case study for pursuing this approach and for further research on incorporating this style of teaching in Science, Technology, Engineering and Mathematics subjects.

Lectures on Lie groups

CERN Document Server

Hsiang, Wu-Yi

2017-01-01

This volume consists of nine lectures on selected topics of Lie group theory. We provide the readers a concise introduction as well as a comprehensive 'tour of revisiting' the remarkable achievements of S Lie, W Killing, É Cartan and H Weyl on structural and classification theory of semi-simple Lie groups, Lie algebras and their representations; and also the wonderful duet of Cartans' theory on Lie groups and symmetric spaces.With the benefit of retrospective hindsight, mainly inspired by the outstanding contribution of H Weyl in the special case of compact connected Lie groups, we develop the above theory via a route quite different from the original methods engaged by most other books.We begin our revisiting with the compact theory which is much simpler than that of the general semi-simple Lie theory; mainly due to the well fittings between the Frobenius-Schur character theory and the maximal tori theorem of É Cartan together with Weyl's reduction (cf. Lectures 1-4). It is a wonderful reality of the Lie t...

Lectures on Quantum Mechanics

CERN Document Server

Basdevant, Jean-Louis

2007-01-01

Beautifully illustrated and engagingly written, Lectures on Quantum Mechanics presents theoretical physics with a breathtaking array of examples and anecdotes. Basdevant's style is clear and stimulating, in the manner of a brisk classroom lecture that students can follow with ease and enjoyment. Here is a sample of the book's style, from the opening of Chapter 1: "If one were to ask a passer-by to quote a great formula of physics, chances are that the answer would be 'E = mc2'. Nevertheless, the formula 'E=hV' which was written in the same year 1905 by the same Albert Einstein, and which started quantum theory, concerns their daily life considerably more. In fact, of the three watershed years for physics toward the beginning of the 20th century - 1905: the Special Relativity of Einstein, Lorentz and Poincaré; 1915: the General Relativity of Einstein, with its extraordinary reflections on gravitation, space and time; and 1925: the full development of Quantum Mechanics - it is surely the last which has the mos...

Enhancing learning: A comparison of lecture and gaming outcomes.

Science.gov (United States)

Gipson, Mary; Bear, Mary

2013-01-01

Contrary to what we anticipated, our outcomes indicated that learning and satisfaction with learning were no different between the traditional lecture group and the educational gaming group. Learners in the gaming group scored on the examination just as well as, but no higher than, did those in the lecture group. Similarly, students in the gaming group were just as, but no more, satisfied with their learning than were students in the lecture group. Of note, both teaching/learning strategies were shown to be effective for learning with students earning a B average on the examination. Likewise, students in both groups were very satisfied with their respective teaching/learning strategies. Given that our assessment did not support gaming as a superior teaching/learning strategy over lecture, what remains now is the need for a longitudinal study to determine if there are differences in long-term learning. As we implement creative methods of instruction, it is also important to test their effectiveness to ensure that the teaching-learning process is evidence based.

Modelling lecturer performance index of private university in Tulungagung by using survival analysis with multivariate adaptive regression spline

Science.gov (United States)

Hasyim, M.; Prastyo, D. D.

2018-03-01

Survival analysis performs relationship between independent variables and survival time as dependent variable. In fact, not all survival data can be recorded completely by any reasons. In such situation, the data is called censored data. Moreover, several model for survival analysis requires assumptions. One of the approaches in survival analysis is nonparametric that gives more relax assumption. In this research, the nonparametric approach that is employed is Multivariate Regression Adaptive Spline (MARS). This study is aimed to measure the performance of private university’s lecturer. The survival time in this study is duration needed by lecturer to obtain their professional certificate. The results show that research activities is a significant factor along with developing courses material, good publication in international or national journal, and activities in research collaboration.

Extension lectures: the effects of radiation from atomic bombing

About 56,000 A-bomb survivors are living in Nagasaki city even today. Nagasaki citizens, whether they are A-bomb survivors or not, can not live without concerns on the existence of radiation effects. They have fears of any amount of radiation and are afraid that it may harm their life. As results of studies in the university on radiation effects are not familiar to the citizens, we have started extension lectures on 'the effects of radiation from A-bombing' to them since 1990. We discuss the problems as well as significance of the extension lectures by reporting the details of the extension lectures which we have managed in the past. (author)

How is the Inquiry Skills of Biology Preservice Teachers in Biotechnology Lecture?

Science.gov (United States)

Hayat, M. S.; Rustaman, N. Y.

2017-09-01

This study was to investigate the inquiry skills of biology pre-service teachers in one teachers college in Central Java in biotechnology lecture. The method used is a case study of 29 biology preservice teacher. Data were collected using observation sheets, questionnaires, and interview guidelines. Research findings collected through questionnaires show that most students are accustomed to asking questions and formulating biotechnology issues; Skilled in conducting experiments; Skilled in obtaining relevant information from various sources; As well as skilled at processing, analyzing and interpreting data. Based on observation: lectures are not dominated by lecturers, students are able to solve problems encountered and conduct investigations. Based on the interview towards lecturers: students are always actively involved in questioning, investigation, inquiry, problem solving and experimenting in lectures. Why do most students show good inquiry skills? Because students are accustomed to invited inquiry in biology lectures. The impact, the students become more ready to be invited to do more advanced inquiry, such as real-world application inquiry, because the skill of inquiry is essentially trained.

The Winfrith lecturers' demonstration kits for radiation and radioactivity

International Nuclear Information System (INIS)

Woffinden, G.B.

1981-01-01

During the early part of the 1970s a need arose for suitable aids to assist lecturers in giving talks on radioactivity and radiation to employees and occasionally to science students in local schools and colleges. A kit capable of demonstrating the basic properties of alpha, beta and gamma radiation was assembled for these purposes. During the latter half of the decade a demand arose for talks to non-scientific groups of the general public on nuclear power and radiation and some of the items in the original demonstration kit were found to be appropriate for these talks. The items used, now constitute the Basic Demonstration Kit. Meanwhile, a few changes or additions were made to the original kit which is now known as the Comprehensive Demonstration Kit. (author)

Should Attendance Be Required in Lecture Classrooms in Dental Education? Two Viewpoints: Viewpoint 1: Attendance in the Lecture Classroom Should Be Required and Viewpoint 2: Attendance Should Not Be Required in the Lecture Classroom.

Science.gov (United States)

Cutler, Christopher W; Parise, Mary; Seminario, Ana Lucia; Mendez, Maria Jose Cervantes; Piskorowski, Wilhelm; Silva, Renato

2016-12-01

This Point/Counterpoint discusses the long-argued debate over whether lecture attendance in dental school at the predoctoral level should be required. Current educational practice relies heavily on the delivery of content in a traditional lecture style. Viewpoint 1 asserts that attendance should be required for many reasons, including the positive impact that direct contact of students with faculty members and with each other has on learning outcomes. In lectures, students can more easily focus on subject matter that is often difficult to understand. A counter viewpoint argues that required attendance is not necessary and that student engagement is more important than physical classroom attendance. This viewpoint notes that recent technologies support active learning strategies that better engage student participation, fostering independent learning that is not supported in the traditional large lecture classroom and argues that dental education requires assimilation of complex concepts and applying them to patient care, which passing a test does not ensure. The two positions agree that attendance does not guarantee learning and that, with the surge of information technologies, it is more important than ever to teach students how to learn. At this time, research does not show conclusively if attendance in any type of setting equals improved learning or ability to apply knowledge.

Selected Topics in Nuclear Theory. Lectures Given at the International Summer School on Selected Topics in Nuclear Theory

Energy Technology Data Exchange (ETDEWEB)

Janouch, F. [ed.

1963-01-15

An International Summer School on Selected Topics in Nuclear Theory was held during the period 20 August to 9 September 1962 in the Low Tatra Mountains, Czechoslovakia, under the auspices of the Nuclear Research Institute of the Czechoslovak Academy of Sciences, with financial support from the International Atomic Energy Agency. In view of the wide interest of the seven topics considered there and of the speed with which the field of theoretical physics is developing, the Agency decided to make available its facilities for rapid publication and to publish the lectures under its own imprint; however, all editorial and composition work has been performed under the supervision of the general editor. Dr. F. Janouch of the Nuclear Research Institute of the Czechoslovak Academy of Sciences. The problem of keeping in touch with the rapidly changing but fundamental field of theoretical physics is a difficult one, particularly for scientists in the developing countries. It is hoped that such publications as the present one and the companion volume containing the lectures presented at the Agency's Seminar on Theoretical Physics at Trieste w ill help, at least in a modest fashion, to overcome these difficulties.

Therefore, this study aims at examining whether lecturing skills of faculty could predict their PBL tutoring skills. Methods: This study included evaluation of faculty (n=69 who participated in both tutoring and lecturing within particular PBL units at the College of Medicine and Medical Sciences (CMMS, Arabian Gulf University, Bahrain. Each faculty was evaluated by medical students (n=45±8 for lecturing and 8±2 for PBL tutoring using structured evaluation forms based on a Likert-type scale (poor to excellent. The prediction of tutoring skills using lecturing skills was statistically analyzed using stepwise linear regression. Results: Among the parameters used to judge lecturing skills, the most important predictor for tutoring skills was subject matter mastery in the lecture by explaining difficult concepts and responding effectively to students' questions. Subject matter mastery in the lecture positively predicted five tutoring skills and accounted for 25% of the variance in overall effectiveness of the PBL tutors (F=22.39, P=0.000. Other important predictors for tutoring skills were providing a relaxed class atmosphere and effective use of audiovisual aids in the lecture. Conclusion: Predicting the tutoring skills based on lecturing skills could have implications for recruiting tutors in PBL medical programs and for tutor training initiatives. Keywords: PBL, tutor, tutoring skills, lecturing skills

The Business of Experimental Physics: Instrument Makers and Itinerant Lecturers in the German Enlightenment

Science.gov (United States)

Hochadel, Oliver

2007-06-01

While it is a commonplace in the historiography of electricity that itinerant lecturers and instrument makers were `somehow' part of the `electrical flare' of the 18th century, very little is actually known about them, about their background, their careers and their self-understanding. Yet, research focusing on these practitioners of experimental physics outside the established institutions can contribute immensely to our understanding of the scientific culture of the Enlightenment. The development of electrical machines, the supply for increasing demand for instruments and instruction, the creation of interest in electricity through public demonstrations, relied heavily on these men. Furthermore, these `scientific salesmen' offered a perfect contrast, a foil for the natural philosophers from whom to distinguish themselves. Natural philosophers tried to discredit their extra-academic competitors, thereby forging their own image as serious, honest, truth-seeking, independent researchers. This essay focuses on this situation in the German Empire, tracing the steps of the itinerant lecturer Jakob von Bianchy on his way from court to college, from the workshop to the theatre, from Lake Como, to Vienna and Paris.

2017-01-01

Live-streaming video has had increasing uses in medical education, especially in distributed education models. The literature on the impact of live-streaming in non-distributed education models, however, is scarce. To determine the attitudes towards live-streaming and recorded lectures as a resource to pre-clerkship medical students in a non-distributed medical education model. First and second year medical students were sent a voluntary cross-sectional survey by email, and were asked questions on live-streaming, recorded lectures and in person lectures using a 5-point Likert and open answers. Of the 118 responses (54% response rate), the data suggested that both watching recorded lectures (Likert 4.55) and live-streaming lectures (4.09) were perceived to be more educationally valuable than face-to-face attendance of lectures (3.60). While responses indicated a statistically significant increase in anticipated classroom attendance if both live-streaming and recorded lectures were removed (from 63% attendance to 76%, p =0.002), there was no significant difference in attendance if live-streaming lectures were removed but recorded lectures were maintained (from 63% to 66%, p=0.76). The addition of live-streaming lectures in the pre-clerkship setting was perceived to be value added to the students. The data also suggests that the removal of live-streaming lectures would not lead to a statistically significant increase in classroom attendance by pre-clerkship students.

2013-01-01

Purpose: To demonstrate that virtual lectures can substitute conventional lectures in radiology education for medical students. Methods and materials: During the course 2005–2006, 89 out from 191 (46.6%) third year students of a subject entitled “General Radiology”, participated voluntarily in a pilot study including 22 virtual lectures (Flash presentations translated from the same PowerPoint presentations of conventional lectures, adding recorded narration and navigation tools). Participants (P) studied by means of virtual lectures, while non-participants (NP) assisted to conventional lectures. The results of the final oral exam classified from 0 to 3, and a 60-questions evaluation on image interpretation were used to compare both groups after training. Finally, 34 students from the group P (38.2%) fulfilled a 10-points scale quality survey about the project. Results: Final exam qualifications were significantly higher for P than for NP (2.11 ± 0.85 versus 1.73 ± 1.04) as well as the number of correct answers of the evaluation on image interpretation (24.2 ± 6.2 versus 21.2 ± 5.4), but differences could obey to different attitudes between both groups. The usefulness of virtual lectures to learn General Radiology obtained the highest global scoring (8.82 ± 1.00). Contents were generally better evaluated than the design of the presentations. Conclusion: Virtual lectures can substitute conventional lectures in radiology education for medical students with no detriment to students’ learning. Their potential advantage is that magisterial lectures can be used to discuss contents with students in a more participative way if virtual lectures are provided before

Attention span during lectures: 8 seconds, 10 minutes, or more?

Science.gov (United States)

Bradbury, Neil A

2016-12-01

In the current climate of curriculum reform, the traditional lecture has come under fire for its perceived lack of effectiveness. Indeed, several institutions have reduced their lectures to 15 min in length based upon the "common knowledge" and "consensus" that there is a decline in students' attention 10-15 min into lectures. A review of the literature on this topic reveals many discussions referring to prior studies but scant few primary investigations. Alarmingly, the most often cited source for a rapid decline in student attention during a lecture barely discusses student attention at all. Of the studies that do attempt to measure attention, many suffer from methodological flaws and subjectivity in data collection. Thus, the available primary data do not support the concept of a 10- to 15-min attention limit. Interestingly, the most consistent finding from a literature review is that the greatest variability in student attention arises from differences between teachers and not from the teaching format itself. Certainly, even the most interesting material can be presented in a dull and dry fashion, and it is the job of the instructor to enhance their teaching skills to provide not only rich content but also a satisfying lecture experience for the students.

General remarks by Angelo Bassi and GianCarlo Ghirardi During the autumn of 1989 the International Centre for Theoretical Physics, Trieste, celebrated the 25th anniversary of its creation. Among the many prestigious speakers, who delivered extremely interesting lectures on that occasion, was the late John Stewart Bell. All lectures have been recorded on tape. We succeeded in getting a copy of John's lecture. In the lecture, many of the arguments that John had lucidly stressed in his writings appear once more, but there are also extremely interesting new remarks which, to our knowledge, have not been presented elsewhere. In particular he decided, as pointed out by the very choice of the title of his lecture, to call attention to the fact that the theory presents two types of difficulties, which Dirac classified as first and second class. The former are those connected with the so-called macro-objectification problem, the latter with the divergences characterizing relativistic quantum field theories. Bell describes the precise position of Dirac on these problems and he stresses appropriately how, contrary to Dirac's hopes, the steps which have led to a partial overcoming of the second class difficulties have not helped in any way whatsoever to overcome those of the first class. He then proceeds to analyse the origin and development of the Dynamical Reduction Program and draws attention to the problems that still affect it, in particular that of a consistent relativistic generalization.

Stereoscopic three-dimensional (3D) imaging is increasingly used in the teaching of neuroanatomy and although this is mainly aimed at undergraduate medical students, it has enormous potential for enhancing the training of neurosurgeons. This study aims to assess whether 3D lecturing is an effective method of enhancing the knowledge and confidence of neurosurgeons and how it compares with traditional two-dimensional (2D) lecturing and cadaveric training. Three separate teaching sessions for neurosurgical trainees were organized: 1) 2D course (2D lecture + cadaveric session), 2) 3D lecture alone, and 3) 3D course (3D lecture + cadaveric session). Before and after each session, delegates were asked to complete questionnaires containing questions relating to surgical experience, anatomic knowledge, confidence in performing procedures, and perceived value of 3D, 2D, and cadaveric teaching. Although both 2D and 3D lectures and courses were similarly effective at improving self-rated knowledge and understanding, the 3D lecture and course were associated with significantly greater gains in confidence reported by the delegates for performing a subfrontal approach and sylvian fissure dissection. Stereoscopic 3D lectures provide neurosurgical trainees with greater confidence for performing standard operative approaches and enhances the benefit of subsequent practical experience in developing technical skills in cadaveric dissection.

Rawls on Dewey before the Dewey Lectures.

Science.gov (United States)

Botti, Daniele

2017-01-01

This article sheds light on John Rawls's views on John Dewey's philosophical temperament by investigating unpublished papers and lectures that Rawls wrote and delivered across the late 1940s, the 1950s, the 1960s, and the early 1970s. Moreover, the article shows that Rawls's rejection of Kant's dualisms predates by at least three decades the "Dewey Lectures" (1980) and that Dewey's notion of deliberation as "dramatic rehearsal in imagination" might have had an impact on Rawls's development of the notion of "reflective equilibrium" as a state of affairs that we strive to reach in ethical reflection.

EGCG-targeted p57/KIP2 reduces tumorigenicity of oral carcinoma cells: Role of c-Jun N-terminal kinase

The green tea polyphenol epigallocatechin-3-gallate (EGCG) regulates gene expression differentially in tumor and normal cells. In normal human primary epidermal keratinocytes (NHEK), one of the key mediators of EGCG action is p57/KIP2, a cyclin-dependent kinase (CDK) inhibitor. EGCG potently induces p57 in NHEK, but not in epithelial cancer cells. In humans, reduced expression of p57 often is associated with advanced tumors, and tumor cells with inactivated p57 undergo apoptosis when exposed to EGCG. The mechanism of p57 induction by EGCG is not well understood. Here, we show that in NHEK, EGCG-induces p57 via the p38 mitogen-activated protein kinase (MAPK) signaling pathway. In p57-negative tumor cells, JNK signaling mediates EGCG-induced apoptosis, and exogenous expression of p57 suppresses EGCG-induced apoptosis via inhibition of c-Jun N-terminal kinase (JNK). We also found that restoration of p57 expression in tumor cells significantly reduced tumorigenicity in athymic mice. These results suggest that p57 expression may be an useful indicator for the clinical course of cancers, and could be potentially useful as a target for cancer therapies

Lectures on the mathematics of quantum mechanics II selected topics

CERN Document Server

Dell'Antonio, Gianfausto

2016-01-01

The first volume (General Theory) differs from most textbooks as it emphasizes the mathematical structure and mathematical rigor, while being adapted to the teaching the first semester of an advanced course in Quantum Mechanics (the content of the book are the lectures of courses actually delivered.). It differs also from the very few texts in Quantum Mechanics that give emphasis to the mathematical aspects because this book, being written as Lecture Notes, has the structure of lectures delivered in a course, namely introduction of the problem, outline of the relevant points, mathematical tools needed, theorems, proofs. This makes this book particularly useful for self-study and for instructors in the preparation of a second course in Quantum Mechanics (after a first basic course). With some minor additions it can be used also as a basis of a first course in Quantum Mechanics for students in mathematics curricula. The second part (Selected Topics) are lecture notes of a more advanced course aimed at giving th...

Stefani, Gianna

2008-01-01

The lectures gathered in this volume present some of the different aspects of Mathematical Control Theory. Adopting the point of view of Geometric Control Theory and of Nonlinear Control Theory, the lectures focus on some aspects of the Optimization and Control of nonlinear, not necessarily smooth, dynamical systems. Specifically, three of the five lectures discuss respectively: logic-based switching control, sliding mode control and the input to the state stability paradigm for the control and stability of nonlinear systems. The remaining two lectures are devoted to Optimal Control: one investigates the connections between Optimal Control Theory, Dynamical Systems and Differential Geometry, while the second presents a very general version, in a non-smooth context, of the Pontryagin Maximum Principle. The arguments of the whole volume are self-contained and are directed to everyone working in Control Theory. They offer a sound presentation of the methods employed in the control and optimization of nonlinear d...

Three lectures on macroscopic aspects of nuclear dynamics

International Nuclear Information System (INIS)

Swiatecki, W.J.

1979-03-01

These lectures concentrate on macroscopic aspects of nuclear dynamics, those aspects that come into prominence when the number of nucleons, A, is large, A >> 1. An attempt is made to set up a theory of the dynamics of nuclear shape changes, for small (sub-sonic) collective velocities. To set up the equations of motion one needs three forces: conservative, dissipative, and inertial. The first lecture deals with statics, i.e., it discusses methods of treating the Potential Energy Function of nuclear systems. From the Potential Energy the conservative forces that drive the time evolution of a nuclear configuration can be deduced. The division of the underlying potential energy into Local, Proximity, and Global terms is stressed. The second lecture deals with dynamical aspects, especially with the nuclear Dissipation Function, which describes how dissipative frictional forces oppose the conservative driving forces. The underlying physics is the approximate validity of the Independent-Particle model. This, combined with the Randomization Hypothesis, leads to simple formulas that suggest that dissipative forces may often overshadow the inertial forces. The third lecture outlines the kind of dynamics that results from the balance of these forces, and describes a number of applications to nuclear fission and heavy-ion collisions of this New Dynamics. Particularly simple equations of motion are set up, and some of the consequences are explored. 18 references, 31 figures, 3 tables

Full Text Available [english] Practising veterinarians in Germany are obliged to take part in continuing education. Due to high expenses which are incurred while taking part in continuing education, such as replacement of personnel, travel costs, conference fees, etc., it is important that efforts toward achievement of learning objectives are maximized. Through the introduction of rapid e-learning techniques, several conferences have been digitised and made available via the internet including publication of CD-ROMs to give participants the possibility of repeated learning. The acceptability of this technique was tested via utilisation data and a survey of participants. It was found that 83.3% of lecturers provided their talks (i.e., a total of approximately 196 lectures for digital distribution. The website featuring the on-line lectures recorded an average of 22 visits per day during a 12-month period. The survey conducted on 82 participants showed a high level of acceptance toward the e-learning technique. In conclusion, there is evidence of a great demand for using new media in continuing education for practitioners of veterinary medicine.

Zhang, Niu; Henderson, Charles N.R.

2016-01-01

Objective: The objective of this study was to evaluate the academic impact of cooperative peer instruction during lecture pauses in an immunology/endocrinology course. Methods: Third-quarter students participated across iterations of the course. Each class offered 20 lectures of 50 minutes each. Classes were divided into a peer-instruction group incorporating cooperative peer instruction and a control group receiving traditional lectures. Peer-instruction group lectures were divided into 2–3 short presentations followed by a multiple-choice question (MCQ). Students recorded an initial answer and then had 1 minute to discuss answers with group peers. Following this, students could submit a revised answer. The control group received the same lecture material, but without MCQs or peer discussions. Final-exam scores were compared across study groups. A mixed-design analysis of covariance was used to analyze the data. Results: There was a statistically significant main effect for the peer-instruction activity (F(1, 93) = 6.573, p = .012, r = .257), with recall scores higher for MCQs asked after peer-instruction activities than for those asked before peer instruction. Final-exam scores at the end of term were greater in the peer-instruction group than the control group (F(1, 193) = 9.264, p = .003, r = .214; question type, F(1, 193) = 26.671, p = .000, r = .348). Conclusion: Lectures with peer-instruction pauses increase student recall and comprehension compared with traditional lectures. PMID:26967766

I will emphasize what can be learnt from cosmology (e.g. the evidence for cold dark matter and the limits on neutrino masses). The third and the fourth lectures will be devoted the direct detection of WIMPs, its technical challenges and the present status. I will describe the recent advances from phonon-mediated detectors which currently provide the best limits and revi...

New Perspectives in Planetarium Lectures: How to Tell Science under the Dome while Preserving the "Enchantment"

Science.gov (United States)

Gandolfi, G.; Catanzaro, G.; Giovanardi, S.; Masi, G.; Vomero, V.

2005-12-01

We discuss the philosophy and strategy of a modern planetarium lecture within the larger frame of the communication of astronomy. The planetarium is a peculiar medium that requires a creative and rigorous approach in order to balance the three motivating forces behind the 'planetarium experience': scientific knowledge (method and contents); technological 'sense of wonder' and a pre-rational (not necessarily anti-rational) sense of 'enchantment'. While scientific and technological resources are typically fully exploited in state-of-the-art domes, the latter concept-introduced by Max Weber in order to categorize the mystic/aesthetic impact of nature on the human mind-has not been sufficiently explored. To use it effectively demands an understanding of the public perception of astronomy, stressing the crucial role of professional communication skills for the effective communication of science. Rather than enforcing a narrow focus on pure science and/or a crusade against astrology, we believe that the planetarium experience should be a stimulating reawakening of curiosity and a holistic awareness of the sky and hence of the Universe. Fine tuning of the above three components makes the classical confl ict between the boring academic lecture under the stars versus disneyish, supertechnological shows obsolete. We present some approaches for creating "fine-tuned lectures", with examples from our experience at the Rome Planetarium.

Lectures on the Topological Vertex

CERN Document Server

Mariño, M

2008-01-01

In this lectures, I will summarize the approach to Gromov–Witten invariants on toric Calabi–Yau threefolds based on large N dualities. Since the large N duality/topological vertex approach computes Gromov–Witten invariants in terms of Chern–Simons knot and link invariants, Sect. 2 is devoted to a review of these. Section 3 reviews topological strings and Gromov–Witten invariants, and gives some information about the open string case. Section 4 introduces the class of geometries we will deal with, namely toric (noncompact) Calabi–Yau manifolds, and we present a useful graphical way to represent these manifolds which constitutes the geometric core of the theory of the topological vertex. Finally, in Sect. 5, we define the vertex and present some explicit formulae for it and some simple applications. A brief Appendix contains useful information about symmetric polynomials. It has not been possible to present all the relevant background and physical derivations in this set of lectures. However, these...

Lectures on matrix field theory

CERN Document Server

Ydri, Badis

2017-01-01

These lecture notes provide a systematic introduction to matrix models of quantum field theories with non-commutative and fuzzy geometries. The book initially focuses on the matrix formulation of non-commutative and fuzzy spaces, followed by a description of the non-perturbative treatment of the corresponding field theories. As an example, the phase structure of non-commutative phi-four theory is treated in great detail, with a separate chapter on the multitrace approach. The last chapter offers a general introduction to non-commutative gauge theories, while two appendices round out the text. Primarily written as a self-study guide for postgraduate students – with the aim of pedagogically introducing them to key analytical and numerical tools, as well as useful physical models in applications – these lecture notes will also benefit experienced researchers by providing a reference guide to the fundamentals of non-commutative field theory with an emphasis on matrix models and fuzzy geometries.

Graduate student driven efforts to increase diversity of department lecture series

Science.gov (United States)

Bryant, R.; Keisling, B. A.

2017-12-01

It is well documented that women and people of color (and especially women of color) remain underrepresented in the geoscience community. As graduate students we noticed this underrepresentation in our department lecture series. Since 2013, 40% of the invited speakers were women and 5% URM, with the majority of the URM scientists coming to campus for an annual special lecture that highlights the work of black geoscientists. Our goals for the 2017-18 lecture series are the following: 1) to increase the percentage of women speakers from 40% to 50% or higher, 2) to increase the participation of URM scientists from one per year to at least one per semester, 3) to expand the established annual special lecture highlighting contributions from black geoscientists from one lecture to four, and 4) to motivate a department-wide conversation surrounding the issues and significance of inclusion and equity in our departmental geoscience community and beyond. Our focus on gender, race, and ethnicity in diversifying the lecture series unfortunately falls short of capturing the full range of perspectives from groups that are underrepresented as defined by the NSF. We see our work as a first step and hope to encourage more conversations about broader diversity. To accomplish our goals, we will seek advice and counsel from scholars in fields like Sociology and Education, as well as pursue external funding to bolster the budget allocated by our department. As graduate students, it is important for us to envision facets of our peers and ourselves reflected in the perspectives, experiences and narratives of prominent speakers brought to campus. We find it therefore important that our department lecture series, a highly visible venue, be more inclusive and representative. Our efforts show that seeking external support and setting achievable goals can lead to better representation of underrepresented groups in such spaces.

Many studies have emphasized the incorporation of active learning into classrooms to reinforce didactic lectures for physiology courses. This work aimed to determine if presenting classic papers during didactic lectures improves the learning of physiology among undergraduate students. Twenty-two students of health information technology were randomly divided into the following two groups: 1) didactic lecture only (control group) and 2) didactic lecture plus paper presentation breaks (DLPP group). In the control group, main topics of gastrointestinal and endocrine physiology were taught using only the didactic lecture technique. In the DLPP group, some topics were presented by the didactic lecture method (similar to the control group) and some topics were taught by the DLPP technique (first, concepts were covered briefly in a didactic format and then reinforced with presentation of a related classic paper). The combination of didactic lecture and paper breaks significantly improved learning so that students in the DLPP group showed higher scores on related topics compared with those in the control group (P physiology.

Lectures on Higgs Boson Physics in the Standard Model and Beyond

CERN Document Server

Wells, James D

2009-01-01

These lectures focus on the structure of various Higgs boson theories. Topics in the first lectures include: mass generation in chiral theories, spontaneous symmetry breaking, neutrino masses, perturbative unitarity, vacuum stability, vacuum alignment, flavor changing neutral current solutions with multiple Higgs doublets, analysis of type I theory with Z2 symmetry, and rephasing symmetries. After an Essay on the Hierarchy Problem, additional topics are covered that more directly relate to naturalness of the electroweak theory. Emphasis is on their connection to Higgs boson physics. Topics in these later lectures include: supersymmetry, supersymmetric Higgs sector in the Runge basis, leading-order radiative corrections of supersymmetric light Higgs boson mass, theories of extra dimensions, and radion mixing with the Higgs boson in warped extra dimensions. And finally, one lecture is devoted to Higgs boson connections to the hidden sector.

Observing the Testing Effect using Coursera Video-recorded Lectures: A Preliminary Study

Full Text Available We investigated the testing effect in Coursera video-based learning. One hundred and twenty-three participants either (a studied an instructional video-recorded lecture four times, (b studied the lecture three times and took one recall test, or (c studied the lecture once and took three tests. They then took a final recall test, either immediately or a week later, through which their learning was assessed. Whereas repeated studying produced better recall performance than did repeated testing when the final test was administered immediately, testing produced better performance when the final test was delayed until a week after. The testing effect was observed using Coursera lectures. Future directions are documented.

On March 11, 2011, a mega earthquake shook the eastern part of Japan, recording a magnitude of 9.0. I have written about my work experience at the university hospital-funded lectures, set up to provide support in the disaster areas. When the lecture was launched, the university did not give official approval to it. For me, it was almost like I had just landed a job at a hospital in a rural area. Now, there are a number of funded lectures mainly in and around disaster-hit areas. I expect that these lectures will narrow down their objectives so that people involved in them will be able to end their tenure happily.

Premature ovarian failure during chemotherapy is a serious problem for young women with cancer. To preserve the fertility of these patients, approaches to prevent chemotherapy-induced ovarian failure are needed. In a previous study, we reported that melatonin treatment prevents the depletion of the dormant follicle pool via repression of the simultaneous activation of dormant primordial follicles by cisplatin. However, melatonin's protective effect was only partial and thus insufficient. In this study, we found that the hormone ghrelin enhances the protective effect of melatonin against cisplatin-induced ovarian failure in mouse model. Co-administration of melatonin and ghrelin more effectively prevented cisplatin-induced follicle disruption. Simultaneous treatment with melatonin and ghrelin almost restored the number of primordial follicles and the corpus luteum in cisplatin-treated ovaries, compared with single administration. We found melatonin and ghrelin receptors on the cell membrane of premature oocytes of primordial follicles. In addition, melatonin and ghrelin co-administration inhibited the cisplatin-induced phosphorylation of PTEN and FOXO3a that induces cytoplasmic translocation of FOXO3a. Inhibition of FOXO3a phosphorylation by melatonin and ghrelin increased the binding affinity of FOXO3a for the p27 Kip1 promoter in primordial follicles. Co-administration of melatonin and ghrelin in cisplatin-treated ovaries restored the expression of p27 Kip1 , which is critical for retention of the dormant status of primordial follicles. In conclusion, these findings suggest that melatonin and ghrelin co-administration is suitable for use as a fertoprotective adjuvant therapy during cisplatin chemotherapy in young female cancer patients. © 2017 John Wiley & Sons A/S.

Active Learning in PhysicsTechnology and Research-based Techniques Emphasizing Interactive Lecture Demonstrations

Science.gov (United States)

Thornton, Ronald

2010-10-01

Physics education research has shown that learning environments that engage students and allow them to take an active part in their learning can lead to large conceptual gains compared to traditional instruction. Examples of successful curricula and methods include Peer Instruction, Just in Time Teaching, RealTime Physics, Workshop Physics, Scale-Up, and Interactive Lecture Demonstrations (ILDs). An active learning environment is often difficult to achieve in lecture sessions. This presentation will demonstrate the use of sequences of Interactive Lecture Demonstrations (ILDs) that use real experiments often involving real-time data collection and display combined with student interaction to create an active learning environment in large or small lecture classes. Interactive lecture demonstrations will be done in the area of mechanics using real-time motion probes and the Visualizer. A video tape of students involved in interactive lecture demonstrations will be shown. The results of a number of research studies at various institutions (including international) to measure the effectiveness of ILDs and guided inquiry conceptual laboratories will be presented.

Integrated lecturing within clerkship course, a new learning method in nurse-anesthesia teaching

Directory of Open Access Journals (Sweden)

Mahmood Akhlaghi

2015-06-01

Full Text Available Background and purpose: Traditional lecture-based teaching has been long used to transit theoretical knowledge to the participants. Due to some problems of this didactic approach, some believe that integration within an active method is more valuable in nursing education. In this study, we hypothesized that integrating lecture-based teaching within clerkship course would enhance nurse-anesthesia students’ knowledge.Methods: A prospective randomized study was conducted. Twenty four students of two-year nurse-anesthesia participated in the study. All of the students received either didactic lectures or integrated lectures within clerkship course during a four-month semester of their educational curriculum. Their knowledge of anesthesia course was assessed at the end of the course using Wilcoxon Rank test.Results: The integrated method improved students’ final scores at the end of the semester (p=0.004. Moreover, their scores was much better when taxonomy-2 questions were compared (p=0.001.Conclusion: Incorporating didactic lecture within anesthesia clerkship course improves participants’ knowledge of anesthesia course.Keywords:  Anesthesia, Lecture, Knowledge, Anesthesia course, Clerkship course

The impact of lecture attendance and other variables on how medical students evaluate faculty in a preclinical program.

High-quality audiovisual recording technology enables medical students to listen to didactic lectures without actually attending them. The authors wondered whether in-person attendance affects how students evaluate lecturers. This is a retrospective review of faculty evaluations completed by first- and second-year medical students at the Ohio State University College of Medicine during 2009-2010. Lecture-capture technology was used to record all lectures. Attendance at lectures was optional; however, all students were required to complete lecturer evaluation forms. Students rated overall instruction using a five-option response scale. They also reported their attendance. The authors used analysis of variance to compare the lecturer ratings of attendees versus nonattendees. The authors included additional independent variables-year of student, student grade/rank in class, and lecturer degree-in the analysis. The authors analyzed 12,092 evaluations of 220 lecturers received from 358 students. The average number of evaluations per lecturer was 55. Seventy-four percent (n = 8,968 evaluations) of students attended the lectures they evaluated, whereas 26% (n = 3,124 evaluations) viewed them online. Mean lecturer ratings from attendees was 3.85 compared with 3.80 by nonattendees (P ≤ .05; effect size: 0.055). Student's class grade and year, plus lecturer degree, also affected students' evaluations of lecturers (effect sizes: 0.055-0.3). Students' attendance at lectures, year, and class grade, as well as lecturer degree, affect students' evaluation of lecturers. This finding has ramifications on how student evaluations should be collected, interpreted, and used in promotion and tenure decisions in this evolving medical education environment.

Full Text Available Universities have experienced increases in technology ownership and usage amongst students entering undergraduate programs. Almost all students report owning a mobile phone and many students view laptops and tablets as educational tools, though they also report using them for non-academic activities during lectures. We explored the relationship between student course engagement and the use of smartphones, laptops, cell phones, and tablets during lecture. Undergraduate students responded to an online survey asking about both course engagement and mobile device habits. Results show that smartphone use was most strongly related to lowered course engagement and while laptop use was related to lowered engagement, it was to a lesser extent. In contrast, overall engagement of students using tablets or cell phones was not significantly different than those who did not.

Using standard mechanics concepts and baseline surveys as well as independent classroom observations, the effects of TA mentorship in Lecture on students' learning of physics concepts and problem-solving skills among different student subgroups taught by other TAs and lecturers using different level of student interactive engagement in classes have been analyzed. Our data indicate that in lecture training of TA promotes lecture/lab synergism in improvement students' learning of mechanics in large introductory physics classes.

The effect of problem-based and lecture-based instructional strategies on learner problem solving performance, problem solving processes, and attitudes

Science.gov (United States)

Visser, Yusra Laila

This study compared the effect of lecture-based instruction to that of problem-based instruction on learner performance (on near-transfer and far-transfer problems), problem solving processes (reasoning strategy usage and reasoning efficiency), and attitudes (overall motivation and learner confidence) in a Genetics course. The study also analyzed the effect of self-regulatory skills and prior-academic achievement on performance for both instructional strategies. Sixty 11th grade students at a public math and science academy were assigned to either a lecture-based instructional strategy or a problem-based instructional strategy. Both treatment groups received 18 weeks of Genetics instruction through the assigned instructional strategy. In terms of problem solving performance, results revealed that the lecture-based group performed significantly better on near-transfer post-test problems. The problem-based group performed significantly better on far-transfer post-test problems. In addition, results indicated the learners in the lecture-based instructional treatment were significantly more likely to employ data-driven reasoning in the solving of problems, whereas learners in the problem-based instructional treatment were significantly more likely to employ hypothesis-driven reasoning in problem solving. No significant differences in reasoning efficiency were uncovered between treatment groups. Preliminary analysis of the motivation data suggested that there were no significant differences in motivation between treatment groups. However, a post-research exploratory analysis suggests that overall motivation was significantly higher in the lecture-based instructional treatment than in the problem-based instructional treatment. Learner confidence was significantly higher in the lecture-based group than in the problem-based group. A significant positive correlation was detected between self-regulatory skills scores and problem solving performance scores in the problem

2017-03-01

Full Text Available Purpose The current study investigates the level of students’ learning and attitudes towards the teaching and learning process when using digital lectures to teach gross anatomy to year 1 medical students. Methods The study sampled year 1 medical students of cohorts 2013 and 2014. The year 1 medical students in 2013 were taught gross anatomy of the heart by didactic classroom lectures while those in 2014 were taught with digital lectures using the same content. A review session was conducted for the 2014 cohort. A 19-item survey was distributed amongst students to investigate their attitudes and feedback. The data were analysed using SPSS software. Results The 2014 cohort had a mean score of 47.65 for short essay questions and 51.19 for multiple choice questions, while the 2013 cohort scored an average of 36.80 for short essay questions and 49.22 for multiple choice questions. The difference in scores for each type of question was found to be significant. Using a 5-point Likert scale, students gave an average of 4.11 when asked if they liked the teaching and learning process and would like it to be applied further. Conclusion The results of the study provide strong evidence that the digital teaching and learning process was well received by students and could also lead to improved performance. Digital lectures can provide a satisfactory substitute for classroom lectures to teach gross anatomy, thus providing flexibility in learning and efficient learning, whilst also freeing lecture slots to promote mastery learning.

What makes lecturers in higher education use emerging technologies in their teaching?

Directory of Open Access Journals (Sweden)

Judy Backhouse

2013-09-01

Full Text Available What makes lecturers in higher education use emerging technologies in their teaching? From the literature we know that lecturers make use of teaching and learning technologies in response to top-down initiatives, and that some also initiate bottom-up experiments with their own teaching practice, driven by both pragmatic and pedagogical concerns. This study is particularly interested in what motivates lecturers to try emerging technologies – those teaching and learning technologies that are new, or are used in new ways, or in new contexts to change teaching practices. This paper analyses the responses of university lecturers in South Africa, who use emerging technologies in their teaching, to a national survey which asked what motivates their practice. The rationales that lecturers use to explain their practices include a mix of pedagogic concerns, pragmatism and external imperatives. These rationales speak to common higher education discourses: effective learning, the welfare of students, and oversight and control; efficiency in the face of the conditions of higher education; as well as the external “imperatives” of the knowledge economy and labour market. Alongside these a discourse of empowerment emerged, including resourcefulness in under-resourced contexts, and creative individual responses to higher education challenges. Such discourses seem to imply that lecturers who engage with emerging technologies are asserting themselves creatively and claiming a more positive positioning in the challenging landscape of modern higher education.

2004-01-01

In case of the SPring-8, accelerator operators are working in three shifts of eight hours. They are making the scheduled beam injection to the storage ring, routine measurements of beam parameters such as the COD, the betatron tunes, the bunch current of stored beam and so on. They are keeping watch on operational state every time. In case of something wrong, they will take measures to meet the situation. Newcomer of operator works with an experienced one to learn sequence of the beam injection, how to operate Graphical User Interface and (GUI) so on. In addition, we organise preliminary lectures on accelerator for operators. Topics done in the lectures are RF system, vacuum system, magnet system, monitors, beam diagnostics, accelerator and beamline control system etc. The contents of the lecture can be seen through web browser again and again. It is useful for operators to understand the SPring-8 facility and details of their work because some of them are not familiar with the accelerator field before being an operator of SPring-8.

Maynor, Lena M; Barrickman, Ashleigh Landis; Stamatakis, Mary K; Elliott, David P

2013-10-14

To describe students' and faculty members' perceptions of the impact of lecture recording in a doctor of pharmacy (PharmD) curriculum. Second- and third-year pharmacy students and faculty members completed an anonymous survey instrument regarding their perceptions of lecture recording with 2 classroom lecture capture software programs, Camtasia Studio and Wimba Classroom. Most students (82%) responded that Camtasia was very helpful and almost half (49%) responded that Wimba Classroom was helpful (pstudents reported being more likely to miss a class that was recorded; however, few students (10%) reported using recordings as a substitute for attending class. The most common concern of faculty members was decreased student attendance (27%). Pharmacy students consider lecture recordings beneficial, and they use the recordings primarily to review the lecture. While faculty members reported concerns with decreased attendance, few students reported using recordings as an alternative to class attendance.

The use of popular movies during lectures to aid the teaching and learning of undergraduate pharmacology.

Ventura, Sab; Onsman, Andrys

2009-07-01

The role of the lecturer has changed to one where they must engage and motivate students to learn the subject material. To investigate whether the use of short movie references to pharmacology during lectures could stimulate learning in undergraduate students. One- to two-min film clips from popular movies containing a reference to the subject being covered were incorporated into Powerpoint presentations and shown at different times during pharmacology lectures. At the end of the lecture series, a student survey was conducted to assess the impact of the movies on student motivation, engagement and learning. Three positive effects were noted. First, students related theory to (simulated) practice by recognising that what they had learnt was actually being used. Second, students were motivated to attend lectures to see what clip would be used. Third, the clips provided a sectioning break, which helped to maintain the engagement of students throughout the lecture as well as the organisation of the lecture by the lecturer. The use of short popular movie references was a novel way to motivate and maintain the interest of large classes of undergraduate students throughout lectures.

Problematic topics in first-year mathematics: lecturer and student views

Science.gov (United States)

Ní Shé, Caitríona; Mac an Bhaird, Ciarán; Ní Fhloinn, Eabhnat; O'Shea, Ann

2017-07-01

In this paper we report on the outcomes of two surveys carried out in higher education institutions of Ireland; one of students attending first-year undergraduate non-specialist mathematics modules and another of their lecturers. The surveys aimed to identify the topics that these students found difficult, whether they had most difficulty with the concepts or procedures involved in the topics, and the resources they used to overcome these difficulties. In this paper we focus on the mathematical concepts and procedures that students found most difficult. While there was agreement between students and lecturers on certain problematic topics, this was not uniform across all topics, and students rated their conceptual understanding higher than their ability to do questions, in contrast to lecturers' opinions.

Student and faculty member perspectives on lecture capture in pharmacy education.

Marchand, Jon-Paul; Pearson, Marion L; Albon, Simon P

2014-05-15

To examine faculty members' and students' use and perceptions of lecture recordings in a previously implemented lecture-capture initiative. Patterns of using lecture recordings were determined from software analytics, and surveys were conducted to determine awareness and usage, effect on attendance and other behaviors, and learning impact. Most students and faculty members were aware of and appreciated the recordings. Students' patterns of use changed as the novelty wore off. Students felt that the recordings enhanced their learning, improved their in-class engagement, and had little effect on their attendance. Faculty members saw little difference in students' grades or in-class engagement but noted increased absenteeism. Students made appropriate use of recordings to support their learning, but faculty members generally did not make active educational use of the recordings. Further investigation is needed to understand the effects of lecture recordings on attendance. Professional development activities for both students and faculty members would help maximize the learning benefits of the recordings.

Everyday Attention and Lecture Retention: The Effects of Time, Fidgeting, and Mind Wandering

Directory of Open Access Journals (Sweden)

James eFarley

2013-09-01

Full Text Available We have all had our thoughts wander from the immediate task at hand. The emerging embodied cognition literature emphasizes the role that the body plays in human thought, and raises the possibility that changes in attentional focus may be associated with changes in body behaviour. Recent research has found that when individuals view a lecture, mind wandering increases as a function of time. In the present study we asked whether this decline in attention during lecture viewing was associated with fidgeting. Participants were filmed while they watched a 40-minute lecture video, and at regular 5 minute intervals provided ratings of their attentiveness. Following the lecture, participant's memory for the material was assessed. Fidgeting behaviour was coded from video recordings of each session. Results indicated that attention to, and retention of, lecture material declined as a function of time on task. Critically, and as predicted, fidgeting also increased with time on task. We also found that the relation between fidgeting and retention was significant even when the role of attention was factored into the equation, suggesting that fidgeting makes a unique contribution to retention of lecture material over and above that contributed by an individual’s attention. We propose a novel non-attentional stress-based account of fidgeting and how this impacts retention for lecture material over and above changes in levels in mind wandering vis-a-vis changes in attention.

The Effects of Instructional Design on Student Engagement with Video Lectures at Cyber Universities

Directory of Open Access Journals (Sweden)

Jamie Costley

2017-05-01

Full Text Available Aim/Purpose: The number of students enrolled in online courses that use video lectures is on the rise. However, research shows that the number of students watching video lectures is low, and the number watching videos to completion is even lower. Background: This paper seeks to understand this problem by looking for correlations between instructional design and student engagement with video lectures. Methodology: Students at a cyber-university in South Korea (n=1801 were surveyed on their perception of the instructional design used in the courses they took and their engagement with online video lectures. Contribution: This paper contributes to the body of knowledge by demonstrating positive correlations between instructional design, watching, and finishing video lectures. Findings: While most other research has found low levels of online lecture viewership, this paper found significantly higher numbers watching and finishing videos. Other major findings of the paper are that five key elements of instructional design for online learning environments (designing methods, setting the curriculum, establishing time parameters, establishing netiquette, and utilizing the medium effectively all correlated positively with students watching and finishing video lectures. Recommendations for Practitioners\t: Based on findings in this paper, it is recommended that practitioners consider taking actions when designing their instruction for online courses. These include batching their video lectures together by topic, devoting greater resources to helping students utilize the medium, and communicate time parameters in a way that encourages students to view video lectures in a timely manner. Recommendation for Researchers: As the watching of video lectures in this study was mandatory for learners, an interesting area of further research would be to examine whether that decision led to higher numbers of students watching them. Future Research: It is important for

Classroom Activities: Simple Strategies to Incorporate Student-Centered Activities within Undergraduate Science Lectures

2012-01-01

The traditional science lecture, where an instructor delivers a carefully crafted monolog to a large audience of students who passively receive the information, has been a popular mode of instruction for centuries. Recent evidence on the science of teaching and learning indicates that learner-centered, active teaching strategies can be more effective learning tools than traditional lectures. Yet most colleges and universities retain lectures as their central instructional method. This article highlights several simple collaborative teaching techniques that can be readily deployed within traditional lecture frameworks to promote active learning. Specifically, this article briefly introduces the techniques of: reader’s theatre, think-pair-share, roundtable, jigsaw, in-class quizzes, and minute papers. Each technique is broadly applicable well beyond neuroscience courses and easily modifiable to serve an instructor’s specific pedagogical goals. The benefits of each technique are described along with specific examples of how each technique might be deployed within a traditional lecture to create more active learning experiences.

[Pedagogical training in stricto sensu graduate programs in public health].

Science.gov (United States)

Corrêa, Guilherme Torres; Ribeiro, Victoria Maria Brant

2013-06-01

The scope of this research is to discuss the relevance and need for pedagogical training of university lecturers in the Public Health field. The contention is that college teaching is a practice that requires specific training, since it is characterized by complex elements that transcend the mastery of given content. Considering stricto sensu graduate studies as an important stage in the training of future university lecturers, an attempt was made to identify and analyze the subjects and practices of pedagogical training in academic masters and doctorate programs in Public Health. To achieve the research aim, this work was based on Pierre Bourdieu's field theory and on Tomaz Tadeu da Silva's curriculum theory. Results indicate that the programs do not consider the aspect of teacher training as a major issue. With regard to the Public Health field approximately 61% of masters and 38% of doctorate programs have pedagogical training subjects/practices. Furthermore, there is a tendency for technical-instrumental training, which is in line with the history of the Public Health field. The conclusion is that there is a need to develop a culture that values college and graduate Public Health teaching, considering the complexity of pedagogical practice in all its dimensions.

Full Text Available Formal lectures have been a traditional part of medical and dental education, but there is debate as to their compulsory status. This study was designed to explore dental and medical students’ views on compulsory lectures and the use of Video-Recorded Lectures (VRL. A cross-sectional study of University of Bristol students in Years 2 to 4 was conducted using an online questionnaire. The majority of both dental (76% and medical (66% students felt lectures should be non-compulsory. The most common learning resources used by both dental and medical students were live lectures, lecture handouts and VRL. The majority of both dental (84% and medical (88% students used VRL. Most students attended lectures all of the time both before and after the introduction of VRL, even though most dental and medical students believe lectures should be non-compulsory. VRL is a popular learning resource. These findings tie-in with General Dental Council and General Medical Council recommendations that encourage self-directed learning. Dental and Medical schools should offer a range of learning resources and make use of current technology, including the use of VRL.

Using Online Video Lectures to Enrich Traditional Face-to-Face Courses

Directory of Open Access Journals (Sweden)

Suzanne C. Makarem

2015-07-01

Full Text Available University educators need to meet changing needs of the digital generation by integrating technology through online content delivery. Despite the many advantages of online education, a large number of university professors are reluctant to make the transition from traditional-face-to-face lectures to online delivery, mainly due to the time, cost, and technical competence requirements to make this transition, in addition to the lack of beliefs in the legitimacy of online education. This article demonstrates the use of online video lectures to adapt traditional university courses to a blended format. The study is implemented for a School of Business Marketing course. We illustrate a cost-effective and timeefficient way for faculty members to record and share online video lectures with limited training and technical support. Using a student sample from two sections of the same marketing course, the study findings support the use of online video lectures as an effective way to free class time for learner-centred activities, without sacrificing student performance outcomes or course satisfaction.

THE HIGHER SCHOOL LECTURE IN THE CONTEXT OF MODERN EDUCATIONAL PROCESSES

V. I. Zagvyazinsky

2014-01-01

Full Text Available The current situation in the higher education requires both the extensive implementation of the new information and communications technologies and transformation of traditional forms and ways of teaching. The author emphasizes the vital necessity of redefining the types, functions, and place of the university lecture in educational process along with the related potentials and advantages. While the mere informative outcome of the lecture is losing its position, the functions related to adjustment, methodology, meaning-building, personal development and moral upbringing are likely to get additional meaning and importance. The author demonstrates the advantages of face-to-face communication between a lecturer and a student; the special emphasis is on the problem-setting lectures implementing the interactive techniques and methods. According to the author, the optimum educational methods and technologies require both the unity and integrity of traditional and modern approaches. The rejection of approbated and recognized methods of interpersonal face-to-face communications can generate the technocratic graduates with a selfish attitude to professional activity and lack of individuality.

Lectures on Black Hole Quantum Mechanics

Science.gov (United States)

Wilczek, Frank

The lectures that follow were originally given in 1992, and written up only slightly later. Since then there have been dramatic developments in the quantum theory of black holes, especially in the context of string theory. None of these are reflected here. The concept of quantum hair, which is discussed at length in the lectures, is certainly of permanent interest, and I continue to believe that in some generalized form it will prove central to the whole question of how information is stored in black holes. The discussion of scattering and emission modes from various classes of black holes could be substantially simplified using modern techniques, and from currently popular perspectives the choice of examples might look eccentric. On the other hand fashions have changed rapidly in the field, and the big questions as stated and addressed here, especially as formulated for "real" black holes (nonextremal, in four-dimensional, asymptotically flat space-time, with supersymmetry broken), remain pertinent even as the tools to address them may evolve. The four lectures I gave at the school were based on two lengthy papers that have now been published, "Black Holes as Elementary Particles," Nuclear Physics B380, 447 (1992) and "Quantum Hair on Black Holes," Nuclear Physics B378, 175 (1992). The unifying theme of this work is to help make plausible the possibility that black holes, although they are certainly unusual and extreme states of matter, may be susceptible to a description using concepts that are not fundamentally different from those we use in describing other sorts of quantum-mechanical matter. In the first two lectures I discussed dilaton black holes. The fact that apparently innocuous changes in the "matter" action can drastically change the properties of a black hole is already very significant: it indicates that the physical properties of small black holes cannot be discussed reliably in the abstract, but must be considered with due regard to the rest of

Public information in radiation emergencies - the messenger, the public and the message

International Nuclear Information System (INIS)

Lackey, J.

1999-01-01

This paper is based on experience as a lecturer on emergency planning courses in east and west Europe, in the USA and in Hong Kong. The complex language of radiation protection confuses the public and so the messenger must avoid unnecessary jargon. In some cases the messenger may have little experience of speaking in public but this can be remedied in exercise and the fear of speaking in public may be reduced. Communication would be more efficient and possibly cause less anxiety if the public was better educated about ionizing radiation. A European initiative is described and the author' s revision of the CEC teacher's manual is reported. The debate over the linear-no-threshold model seems to undermine the credibility of the radiological protection message. The author proposes that a dose threshold should be set, preferably internationally, so those individual doses below threshold could be excluded from records and research effort redirected to more hazardous factors.

Web-based lecture technologies and learning and teaching: a study of change in four Australian universities

Directory of Open Access Journals (Sweden)

M. Gosper

2010-12-01

Full Text Available The uptake of web-based lecture technologies for recording and delivering live lectures has increased markedly in recent years. Students have responded positively, and for many their use has transformed learning – freeing them up from rigid timetables by providing choice in lecture attendance and supporting learning by extending the lecture experience and enabling them to revisit key concepts and ideas in their own time. Less transformational has been the impact on teaching. Although changing attendance patterns and disquiet about the quality of learning are of concern to many, lecturers have largely responded by simply modifying lectures. For most, the challenges of catering for the learning needs of a cohort with variable lecture attendance have not been addressed at a whole of the curriculum level. The technologies have been added on, rather than integrated into the curriculum. This paper will review the changes taking place in learning and teaching, explore the reluctance to embrace more wholesale change to the curriculum, and discuss the implications for institutions in the face of ongoing change.

Opportunities and barriers to public health nutrition education in Vietnamese universities.

Science.gov (United States)

Pham, Quynh Th; Worsley, Anthony; Lawrence, Mark; Marshall, Bernie

2017-05-01

A core challenge for low- and middle-income countries (LMICs) in combating the negative effects of the nutrition transition is to implement appropriate prevention strategies to halt the increasing prevalence of obesity and non-communicable diseases (NCDs), against a background of prevailing under nutrition. There have been several proposals for the enhancement of university nutrition education for future health and related professionals who are expected to communicate knowledge of health risks to the broad community. However, little is known about university nutrition education in LMICs. The present study aimed to investigate professional development opportunities and barriers for university nutrition lecturers to teach public health nutrition (PHN). An online survey was conducted among 242 Vietnamese health and education professionals and university nutrition lecturers across Vietnam. Purposive sampling was used to recruit participants. Comparisons of between the groups' responses were examined via SPSS Crosstabs. The structures of the perceived barriers and desired PHN training topics were examined via factor analyses. Multiple linear regression examined the influences on lecturers' learning interests in nutrition areas. The lecturers' learning interests spanned four areas: basic nutrition, basic food, food policy and 'new' trends (e.g. food policy, marketing). Major impediments to nutrition teaching in universities divided into two groups: resource limitations and professional constraints (e.g. lack of relevant training opportunities). The lecturers' perceptions of professional constraints influenced their interest in learning about 'new' trends. The results highlighted the need and opportunities to enhance PHN professional development for nutrition lecturers in Vietnam.

To identify public health core competencies and contents in pharmacy degrees at a meeting of public health lecturers in pharmacy degrees from various public and private universities. The first Meeting of the Forum of University Teaching Staff in Pharmacy Degrees was held at the Faculty of Medicine in the Complutense University, Madrid, Spain on the 19(th) and 20(th) of November 2013. The meeting was attended by 17 lecturers. Participants brought their own teaching programs and were given two previous studies on public health competencies for analysis of public health contents and competencies in pharmacy degrees. Working groups were formed and the results were shared. The highest number of core competencies was identified in the following functions: "Assessment of the population's health needs" and "Developing health policies". The final program included basic contents organized into 8 units: Concept of Public Health, Demography, Epidemiological Method, Environment and Health, Food Safety, Epidemiology of Major Health Problems, Health Promotion and Education, and Health Planning and Management. Representation of almost all the Spanish Pharmacy Faculties and the consensus reached in the description of competences and program contents will greatly improve the quality of teaching in this area.

Full Text Available Transition from school to university can cause concern for many students. One issue is the gap between students' prior expectations and the realities of university life, which can cause significant distress, poor academic performance and increased drop-out rates if not managed effectively. Research has shown several similarities in the expectations of staff and students in regards to which factors determine academic success, but there is also evidence of dissonance. For example, staff consider independent study and critical evaluation as key factors, whereas students view feedback on drafts of work and support from staff as being most important. The aim of the current study was to determine what expectations students hold when starting university education, and what expectations university lecturers have of students entering university. Lecturers (n = 20 and first year students (n = 77 completed a series of questionnaires concerning their expectations of learning in HE (staff and students and their approach to teaching (staff. Results revealed that students have largely realistic expectations of university. For example, the majority expected to be in charge of their own study. Some unrealistic expectations were also evident, e.g., most expected that teaching would be the same at university as it had been at school. The expectation that lecturers would provide detailed notes varied as a function of student age. Lecturers reported modifying their expectations of students and adapting their teaching approach according to year of study. Information-transmission/teacher-focused style was more common when teaching 1st year students; a more concept-changing/student-focused approach tended to be used when teaching 2nd year students (and above. Lecturer's expectations of student engagement did not differ according to year. Less experienced lecturers reported more negative expectations of student engagement than did experienced lecturers.

Faculty in the physical sciences are one of the academic groups least receptive to the use of active learning strategies and cooperative learning in their classrooms. This is particularly so in traditional lecture classes. It is the objective of this paper to show how effective these techniques can be in improving student performance in classes. The use of active learning strategies and cooperative learning groups in my organic chemistry lecture classes has increased the overall pass rate in my classes by an astounding 20-30% over the traditional lecture mode. This has been accomplished without any reduction in "standards". The actual methods employed are presented as well as a discussion of how I came to radically change the way I teach my classes.
