  1. Alan Turing the enigma

    CERN Document Server

    Hodges, Andrew

    1983-01-01

    It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades--all before his suicide at age forty-one. This classic biography of the founder of computer science, reissued on the centenary of his birth with a substantial new preface by the author, is the definitive account of an extraordinary mind and life. A gripping story of mathematics, computers, cryptography, and homosexual persecution, Andrew Hodges's acclaimed book captures bot

  3. Obituary: Alan D. Fiala (1942-2010)

    Kaplan, George

    2011-12-01

    Dr. Alan Dale Fiala, astronomer and expert on solar eclipses, died on May 26, 2010 in Arlington, Virginia, of respiratory failure after a brief illness. He was 67. Fiala had been a staff astronomer at the U.S. Naval Observatory in Washington, D.C., for his entire professional career, where he rose from a position as a summer intern to become the Chief of the Nautical Almanac Office, responsible for annual publications for astronomy and navigation that are used the world over. He retired from the observatory in 2000. Although a childhood case of polio affected his mobility for the rest of his life, he seldom let his physical constraints limit his activities, which were many and varied. Alan Fiala was born in Beatrice, Nebraska on November 9, 1942, the middle son of Emil A. ("John") and Lora Marie Fiala. Fiala's father was a postal clerk and Civil Service examiner. Fiala expressed interest in astronomy at a very young age. He contracted polio when he was 9. He graduated from Beatrice High School in 1960 with a straight-A average and went on to study at Carleton College. He received his B.A. summa cum laude after three years, in 1963, with a major in astronomy and minors in physics and mathematics. He was elected to Phi Beta Kappa, Sigma Xi, and Pi Mu Epsilon (mathematics). In 1962, Alan Fiala obtained a job as a summer intern at the Naval Observatory in Washington, working in the Nautical Almanac Office (NAO). He entered the graduate program at Yale University and continued to work summers at the observatory. He received his Ph.D. in 1968, under Gerald Clemence. His dissertation was titled "Determination of the Mass of Jupiter from a Study of the Motion of 57 Mnemosyne." After receiving his doctorate, Fiala became a permanent member of the Naval Observatory staff. Computers were just being introduced there and he participated in the automation of many procedures used to prepare the annual publications of the Nautical Almanac Office. One of his first assignments was

    Huan, Tran Doan; Amsler, Maximilian; Marques, Miguel A. L.; Botti, Silvana; Willand, Alexander; Goedecker, Stefan

    2013-03-01

    Low-energy structures of alanates are currently known to be described by patterns of isolated, nearly ideal tetrahedral [AlH4] anions and metal cations. We discover that the novel polymeric motif recently proposed for LiAlH4 plays a dominant role in a series of alanates, including LiAlH4, NaAlH4, KAlH4, Mg(AlH4)2, Ca(AlH4)2, and Sr(AlH4)2. In particular, most of the low-energy structures discovered for the whole series are characterized by networks of corner-sharing [AlH6] octahedra, forming wires and/or planes throughout the materials. Finally, for Mg(AlH4)2 and Sr(AlH4)2, we identify two polymeric phases to be lowest in energy at low temperatures.

  18. A reversible hydrogen storage mechanism for sodium alanate: the role of alanes and the catalytic effect of the dopant

    Energy Technology Data Exchange (ETDEWEB)

    Walters, R. Tom [707 Cardinal Drive, Aiken, SC 29803 (United States)]. E-mail: jdtwalters@mindspring.com; Scogin, John H. [707 Cardinal Drive, Aiken, SC 29803 (United States)

    2004-10-06

    We propose a reversible hydrogen storage mechanism for cycled sodium alanate. The individual mechanistic reaction steps for the decomposition reaction derive a set of time-dependent differential equations that simultaneously produce the evolution plots for each species. These plots reproduce several aspects of in situ X-ray diffraction (XRD) data, as well as the measured relative composition of selected decomposition samples at various extents of reaction. The presence of alanes facilitates both the decomposition and reformation of sodium alanate based on the principle of microscopic reversibility. A major role for the titanium dopant in catalyzed sodium alanate dynamics may be alloy formation at or near the surface of bulk aluminum that facilitates the formation and sorption properties of alanes.

    The papers presented here, in this special volume dedicated to the memory of Alan Turner (1947-2012), provide a glimpse of the multi-faceted ways in which the mammalian fossil record can be investigated. The authors of contributions in this Special Issue are by no means an exhaustive list of his international collaborators and colleagues, and indeed, many are not represented here, but the contents cover many of the topics and issues that were of central archaeological and wider Quaternary mammalian interest to Alan. Although the papers are not intended to provide a comprehensive overview of all techniques that can be applied, the set nevertheless reveals a snapshot of the state-of-the-art and of some of the methods that have the potential to bring much more of the past to life. Alan always sought to move beyond the 'stamp-collecting' approach of simply listing which taxa were present at a site, attempting to elucidate what the presence of those animals might mean in terms of palaeoecology. In particular, the span of Alan's career has seen major advances in our understanding of Quaternary mammalian biostratigraphy and palaeobiogeography, the widespread application of novel techniques such as ancient DNA, the development of high-precision geochronology and the discovery of new hominin species. The papers presented here reflect those developments and highlight interdisciplinary approaches, from examination of sediments to careful measurements of the fossils themselves, from modelling the presence of taxa at particular points in the Quaternary to examination of the similarities and differences in fauna within and between sites.

  3. Development of hydrogen storage systems using sodium alanate

    Lozano Martinez, Gustavo Adolfo

    2010-12-06

    In this work, hydrogen storage systems based on sodium alanate were studied, modelled and optimised, using both experimental and theoretical approaches. The experimental approach covered investigations of the material from mg scale up to kg scale in demonstration test tanks, while the theoretical approach discussed modelling and simulation of the hydrogen sorption process in a hydride bed. Both approaches demonstrated the strong effect of heat transfer on the sorption behaviour of the hydride bed and led to feasible methods to improve and optimise the volumetric and gravimetric capacities of hydrogen storage systems. The applied approaches aimed at an optimal integration of sodium alanate material in practical hydrogen storage systems. First, it was experimentally shown that the size of the hydride bed influences the hydrogen sorption behaviour of the material. This is explained by the different temperature profiles that are developed inside the hydride bed during the sorptions. In addition, in a self-constructed cell it was possible to follow the hydrogen sorptions and the developed temperature profiles within the bed. Moreover, the effective thermal conductivity of the material was estimated in-situ in this cell, given very good agreement with reported values of ex-situ measurements. It was demonstrated that the effective thermal conductivity of the hydride bed can be enhanced by the addition of expanded graphite. This enhancement promotes lower temperature peaks during the sorptions due to faster heat conduction through the bed, which in addition allows faster heat transfer during sorption. Looking towards simulations and further evaluations, empirical kinetic models for both hydrogen absorption and desorption of doped sodium alanate were developed. Based on the results of the model, the optimal theoretical pressure-temperature conditions for hydrogen sorptions were determined. A new approach is proposed for the mass balance of the reactions when implementing

    2014-01-01

    Inevitably, there are times in a nation’s history when its hopes, fears and confidence in its own destiny appear to hinge on the fate of a single person. One of these pivotal moments occurred on the early morning of May 5, 1961, when a 37-year-old test pilot squeezed himself into the confines of the tiny Mercury spacecraft that he had named Freedom 7. On that historic day, U.S. Navy Commander Alan Shepard carried with him the hopes, prayers, and anxieties of a nation as his Redstone rocket blasted free of the launch pad at Cape Canaveral, hurling him upwards on a 15-minute suborbital flight that also propelled the United States into the bold new frontier of human space exploration. This book tells the enthralling story of that pioeering flight as recalled by many of the participants in the Freedom 7 story, including Shepard himself, with anecdotal details and tales never before revealed in print. Although beaten into space just three weeks earlier by the Soviet cosmonaut Yuri Gagarin, Alan Shepard’s h...

    Post-translational modifications of core histones are important for various DNA-templated processes such as transcription and repair. We recently reported that the ALFIN LIKE 6 (AL6) gene, identified in a forward genetic screen, is critical for phosphate deficiency-induced root hair formation and several other processes associated with the regulation of cellular phosphate homeostasis. AL6 contains a Plant Homeo Domain (PHD) finger that can bind to trimethylated lysine 4 of histone H3 (H3K4me3). Homozygous mutants defective in AL6 expression form very short root hairs under phosphate-deficient conditions, presumably caused by altered expression of putative primary and secondary down-stream targets of AL6. In this Addendum, we speculate about possible roles of AL6, H3K4 trimethylation and other chromatin modifications in the adaptation of plants to low phosphate availability. PMID:23531693

    Alan WIlliams is noted for his seminal contributions to the field of leucocyte membrane glycoproteins (that is, differentiation antigens). He played a leading role in the development of approaches to the purification and structural analysis of cell surface antigens. His comprehensive characterization of the structure of the rat Thy-1 antigen, as well as the application of monoclonal antibodies to the designation and subsequent isolation of multiple new leucocyte antigens, were exemplary. His discovery that Thy-1 is structurally related to immunoglobulin led directly to the concept of the immunoglobulin (Ig) superfamily, which embraced a spectrum of cell surface molecules involved in a variety of cell recognition systems. He was a very strong advocate in support of the rat as a model animal in the study of immunological phenomena. He was energetic and courageous, as well as radiating enthusiasm for immunological research, inspiring others, critically analysing accepted dogmas and setting high standards. In short, he was a brilliant research scientist.

  10. Alan Turing and the origins of modern Gaussian elimination

    Directory of Open Access Journals (Sweden)

    Dopico, Froilán M.

    2013-12-01

    Full Text Available The solution of a system of linear equations is by far the most important problem in Applied Mathematics. It is important both in itself and because it is an intermediate step in many other important problems. Gaussian elimination is nowadays the standard method for solving this problem numerically on a computer and it was the first numerical algorithm to be subjected to rounding error analysis. In 1948, Alan Turing published a remarkable paper on this topic: “Rounding-off errors in matrix processes” (Quart. J. Mech. Appl. Math. 1, pp. 287-308. In this paper, Turing formulated Gaussian elimination as the matrix LU factorization and introduced the “condition number of a matrix”, both of them fundamental notions of modern Numerical Analysis. In addition, Turing presented an error analysis of Gaussian elimination for general matrices that deeply influenced the spirit of the definitive analysis developed by James Wilkinson in 1961. Alan Turing’s work on Gaussian elimination appears in a fascinating period for modern Numerical Analysis. Other giants of Mathematics, as John von Neumann, Herman Goldstine, and Harold Hotelling were also working in the mid-1940s on Gaussian elimination. The goal of these researchers was to find an efficient and reliable method for solving systems of linear equations in modern “automatic computers”. At that time, it was not clear at all whether Gaussian elimination was a right choice or not. The purpose of this paper is to revise, at an introductory level, the contributions of Alan Turing and other authors to the error analysis of Gaussian elimination, the historical context of these contributions, and their influence on modern Numerical Analysis.La resolución de sistemas de ecuaciones lineales es sin duda el problema más importante en Matemática Aplicada. Es importante en sí mismo y también porque es un paso intermedio en la resolución de muchos otros problemas de gran relevancia. La eliminaci

    The road to becoming an astronomer is exciting, but often fraught with danger and conflicting messages. A PhD student is inundated with catch-phrases such as "publish or perish" and "it's not about the quantity, but the quality of work". How do we know which advice to follow? How can we publish copious amounts of quality work in only three years so as to maximize our success in the future? How do we even know what "good quality" really is? With only a short time to prepare ourselves for the big wide world of Astronomy, what is the best way for a PhD student to maximize their research and ultimately maximize their success as a real astronomer? The PhD students of today are the astronomers of tomorrow, but their journey depends on a positive work environment in which they can thrive and improve. Here I present the results of a survey of current PhD students on how they believe they can maximize their success in science. I find that PhD students in Australia expect to write more papers during their PhD than is e...

    Full Text Available The electrochemical alane production process was proposed for a feasible production of alane. The operation of process was difficult because of short circuit by a dendrite growth in the reactor. Therefore, characteristics of the dendrite growth in the process were investigated. We conducted the electrochemical alane production process using Teflon block for inhibition of the dendrite growth. The obtained dendrite was characterized by XRD, SEM and ICP-AES. It was concluded that the dendrite growth was attributed to a melting and agglomeration of Al fine particles existed in the solution.

  1. LEDs/ALAN-Working To Be Good Neighbors

    Adams, Robert

    2015-08-01

    ALAN (Artificial Light At Night) and LEDs have recently become major discussion topics in the areas of astronomy, light pollution, endangered species and human health to mention but a few. In years past, MH, LPS and HPS dominated night lighting with LPS and its associated narrow spectrum as the preferred source around observatories and shorelines. LEDs offer the ability to modify the spectrum, realize substantial energy savings and other associated benefits while meeting the requirements of the astronomy community.The primary concern of the different groups relates to blue light content of the LED. For astronomers, the molecular (Raleigh) scattering related to the blue light interferes with certain portions of the spectrum used for deep space studies. The ecologists studying various endangered species find blue and green light can be related to declining leatherback turtle population in certain areas of the world. Other animals ranging from bats to moths and other insects are now being studied to determine the effect of the blue light spectrum on their behavior. The impact of blue light on the human circadian rhythm and vision, especially in the older population, is being extensively studied today.This presentation will discuss the spectral power distribution (SPD) of various light sources, the performance of new LED solutions and how the SPD of these new LED’s can be adapted to address some of the issues raised by various constituencies. A discussion describing why some of the metrics used to describe standard lighting are not adequate for specifying the new LED solutions with the modified spectra will be included.Today, lighting plans and implementation are all too often based on opinions and limited data. The ensuing problems and repercussions make it imperative to collect accurate and thorough information. Data collection is now ongoing using a variety of techniques analyzing the “before” and “after” lighting results from the C of HI LED streetlight

    Nowadays, hydrogen is highly interesting as an energy source, in particular in the automotive field. In fact, hydrogen is attractive as a fuel because it prevents air pollution and greenhouse emissions. One of the main problems with the utilization of hydrogen as a fuel is its on-board storage. The purpouse of this work was to develop a new hybrid material consisting of a polyaniline matrix with sodium alanate (NaAlH{sub 4}) using a spray-drying process. The polyaniline used for this experiment was synthesized by following a well-established method for the synthesis of the emeraldine base form of polyaniline using dodecylbenzenesulfonic acid as dopant. Micro particles of polyaniline/sodium alanate hybrids with 30 and 50 wt% of sodium alanate were prepared by using a spray-drying technique. Dilute solutions of polyaniline/sodium alanate were first prepared, 10g of the solid materials were mixed with 350 ml of toluene under stirring at room temperature for 24h and the solutions were dried using spray-dryer (Büchi, Switzerland) with 115°C of an inlet temperature. The hybrids were analyzed by differential scanning calorimetry, FT-IR and scanning electron microscopy (SEM). The addition of sodium alanate decreased the glass transition temperature of the hybrids when compared to neat polyaniline. FT-IR spectrum analysis was performed to identify the bonding environment of the synthesized material and was observed that simply physically mixture occurred between polyaniline and sodium alanate. The SEM images of the hybrids showed the formation of microspheres with sodium alanate dispersed in the polymer matrix.

    Cellular oxygen tension is sensed by a family of prolyl hydroxylases (PHD1-3) that regulate the degradation of hypoxia-inducible factors (HIF-1{alpha} and -2{alpha}). The PHD2 isoform is considered as the main downregulator of HIF in normoxia. Our previous results have shown that nuclear translocation of PHD2 associates with poorly differentiated tumor phenotype implying that nuclear PHD2 expression is advantageous for tumor growth. Here we show that a pool of PHD2 is shuttled between the nucleus and the cytoplasm. In line with this, accumulation of wild type PHD2 in the nucleus was detected in human colon adenocarcinomas and in cultured carcinoma cells. The PHD2 isoforms showing high nuclear expression increased anchorage-independent carcinoma cell growth. However, retention of PHD2 in the cytoplasm inhibited the anchorage-independent cell growth. A region that inhibits the nuclear localization of PHD2 was identified and the deletion of the region promoted anchorage-independent growth of carcinoma cells. Finally, the cytoplasmic PHD2, as compared with the nuclear PHD2, less efficiently downregulated HIF expression. Forced HIF-1{alpha} or -2{alpha} expression decreased and attenuation of HIF expression increased the anchorage-independent cell growth. However, hydroxylase-inactivating mutations in PHD2 had no effect on cell growth. The data imply that nuclear PHD2 localization promotes malignant cancer phenotype.

Using density functional theory, we examine the defect-mediated formation of alane monomers on Al(111) in a two-step process: (1) dissociative adsorption of H2 and (2) alane formation, which are both endothermic on a clean surface. Only with Ti dopant to facilitate H2 dissociation and vacancies to provide Al adatoms, both processes become exothermic. In agreement, in situ scanning tunneling microscopy showed that during H2 exposure, alane monomers and clusters form primarily in the vicinity of Al vacancies and Ti atoms. Moreover, ball milling of the Al samples with Ti (providing necessary defects) showed a 10 % conversion of Al into AlH3 or closely related species at 344 bar H2 , indicating that the predicted pathway may lead to the direct synthesis of alane from elements at pressures much lower than the 10(4)  bar expected from bulk thermodynamics.

  9. Artificial Intelligence, Evolutionary Computing and Metaheuristics In the Footsteps of Alan Turing

    CERN Document Server

    2013-01-01

    Alan Turing pioneered many research areas such as artificial intelligence, computability, heuristics and pattern formation.  Nowadays at the information age, it is hard to imagine how the world would be without computers and the Internet. Without Turing's work, especially the core concept of Turing Machine at the heart of every computer, mobile phone and microchip today, so many things on which we are so dependent would be impossible. 2012 is the Alan Turing year -- a centenary celebration of the life and work of Alan Turing. To celebrate Turing's legacy and follow the footsteps of this brilliant mind, we take this golden opportunity to review the latest developments in areas of artificial intelligence, evolutionary computation and metaheuristics, and all these areas can be traced back to Turing's pioneer work. Topics include Turing test, Turing machine, artificial intelligence, cryptography, software testing, image processing, neural networks, nature-inspired algorithms such as bat algorithm and cuckoo sear...

    2014-10-01

    Full Text Available In European Higher Education, learning outcomes and competences have been used sometimes with different meanings and sometimes with the same meaning. But both terms have been more commonly used to refer to knowledge, understanding and abilities a student must demonstrate at the end of a learning experience.  Their use is a consequence of the paradigm shift of the Bologna Process to a learner centered education environment. The definition of standards of competences (or learning outcomes for the PhD degree is thus a need for the quality assurance of this degree. In this work, subject-specific and generic competences for the PhD in Food Science and Technology and their alignment with the European Qualifications Framework (EQF level descriptors for quality assurance purposes have been identified.

    2011-01-01

    Knowledge of the relative stabilities of alane (AlH3) complexes with electron donors is essential for identifying hydrogen storage materials for vehicular applications that can be regenerated by off-board methods; however, almost no thermodynamic data are available to make this assessment. To fill this gap, we employed the G4(MP2) method to determine heats of formation, entropies, and Gibbs free energies of formation for thirty-eight alane complexes with NH3-nRn (R = Me, Et; n = 0-3), pyridine, pyrazine, triethylenediamine (TEDA), quinuclidine, OH2-nRn (R = Me, Et; n = 0-2), dioxane, and tetrahydrofuran (THF). Monomer, bis, and selected dimer complex geometries were considered. Using these data, we computed the thermodynamics of the key formation and dehydrogenation reactions that would occur during hydrogen delivery and alane regeneration, from which trends in complex stability were identified. These predictions were tested by synthesizing six amine-alane complexes involving trimethylamine, triethylamine, di...

    Full Text Available he thesis is put forward that changes in public policy which originally promoted broad access to higher education are leading to the diminished likelihood that minorities, those from low-income backgrounds and females in underrepresented disciplines will pursue, or be able to complete, the doctorate. By reviewing a wide range of research literature and statistical reports on the status of doctoral education in the U.S. & Canada, a detailed sociological portrait of those who pursue the Ph.D. is presented. Recommendations are given for further research on doctoral education, particularly in areas of attrition,retention, student indebtedness, social stratification, and post-doctoral career plans.

    Full Text Available Intensive gene targeting studies in mice have revealed that prolyl hydroxylase domain proteins (PHDs play important roles in murine embryonic development; however, the expression patterns and function of these genes during embryogenesis of other vertebrates remain largely unknown. Here we report the molecular cloning of phd1 and systematic analysis of phd1, phd2, and phd3 expression in embryos as well as adult tissues of Xenopus laevis. All three phds are maternally provided during Xenopus early development. The spatial expression patterns of phds genes in Xenopus embryos appear to define a distinct synexpression group. Frog phd2 and phd3 showed complementary expression in adult tissues with phd2 transcription levels being high in the eye, brain, and intestine, but low in the liver, pancreas, and kidney. On the contrary, expression levels of phd3 are high in the liver, pancreas, and kidney, but low in the eye, brain, and intestine. All three phds are highly expressed in testes, ovary, gall bladder, and spleen. Among three phds, phd3 showed strongest expression in heart.

  3. Alane adsorption and dissociation on the Si(0 0 1) surface

    Science.gov (United States)

    Smith, R. L.; Bowler, D. R.

    2017-10-01

    We used DFT to study the energetics of the decomposition of alane, AlH3, on the Si(0 0 1) surface, as the acceptor complement to PH3. Alane forms a dative bond with the raised atoms of silicon surface dimers, via the Si atom lone pair. We calculated the energies of various structures along the pathway of successive dehydrogenation events following adsorption: AlH2, AlH and Al, finding a gradual, significant decrease in energy. For each stage, we analyse the structure and bonding, and present simulated STM images of the lowest energy structures. Finally, we find that the energy of Al atoms incorporated into the surface, ejecting a Si atom, is comparable to Al adatoms. These findings show that Al incorporation is likely to be as precisely controlled as P incorporation, if slightly less easy to achieve.

    tenured university positions. However, over the past 20–30 years, and particularly the past 10 years, the situation has changed dramatically. Governments in many countries have invested massively in PhD education, believing that trained researchers will contribute to the ‘knowledge society’, and thus...... increase the competitiveness of their countries in the future economies of the world. Thus, only a small fraction of PhD graduates now end up in academic research. Yet, the PhD remains a research degree, and indeed, institutions have become heavily dependent on PhD students for their research output...... during their PhD studies. The purpose of this article is to explore how this seeming paradox is being addressed in biomedicine and to show that far from being inconsistent that the two aspects are in fact complementary.

  13. Hydrogen release properties of lithium alanate for application to fuel cell propulsion systems

    Science.gov (United States)

    Corbo, P.; Migliardini, F.; Veneri, O.

    In this paper the results of an experimental study on LiAlH 4 (lithium alanate) as hydrogen source for fuel cell propulsion systems are reported. The compound examined in this work was selected as reference material for light metal hydrides, because of its high hydrogen content (10.5 wt.%) and interesting desorption kinetic properties at moderate temperatures. Thermal dynamic and kinetic of hydrogen release from this hydride were investigated using a fixed bed reactor to evaluate the effect of heating procedure, carrier gas flow rate and sample form. The aim of this study was to characterize the lithium alanate decomposition through the reaction steps leading to the formation of Li 3AlH 6 and LiH. A hydrogen tank was designed and realized to contain pellets of lithium alanate as feeding for a fuel cell propulsion system based on a 2-kW Polymeric Electrolyte Fuel Cell (PEFC) stack. The fuel cell system was integrated into the power train comprising DC-DC converter, energy storage systems and electric drive for moped applications (3 kW). The experiments on the power train were conducted on a test bench able to simulate the vehicle behaviour and road characteristics on specific driving cycles. In particular the efficiencies of individual components and overall power train were analyzed evidencing the energy requirements of the hydrogen storage material.

    The Beyond the PhD (B-PhD) Professional Development Program is the newest addition to the Minorities Striving and Pursuing Higher Degrees of Success (MS PHD'S®) Professional Development Program in Earth System Science. This exciting new program is designed to facilitate the development of a new community of underrepresented minority (URM) doctoral candidates and recent doctorate degree recipients in Earth system science (ESS)-related fields. Building upon MS PHD'S extensive professional development activities provided to URM undergraduate and graduate students, B-PhD's vision is to encourage and support URM doctoral students and early career PhD's in becoming part of the global workforce. (Since its inception in 2003, MSPHD'S supports 213 participants of which 42 have achieved the doctoral degree and another 71 are enrolled in doctoral programs.) By providing customized support and advocacy for participants, B-PhD facilitates smoother and informed transitions from graduate school to postdoctoral and tenure-track positions, as well as other "first" jobs in academia, government, industry, and non-profit organizations. In 2011, the first conference for 18 doctoral candidate and recent graduates was hosted at the University of Texas at Arlington's (UTA) College of Science. Using a format of guest speakers, brown bag discussions, and interactive breakout sessions, participants engaged in sessions entitled "Toolkits for Success in Academia, Business and Industry, Federal Government and Non-Profits", "Defining Short, Mid and Long Term Career Goals", "Accessing and Refining Skill Sets and Other Door Openers", "International Preparation and Opportunities", "Paying it Forward/Lifting as You Climb", and "Customized Strategies for Next Steps". This presentation will discuss outcomes from this pilot project, the use of social media to track and support ongoing B-PhD activities, and objectives for future B-PhD workshops.

    In the framework of long-term scientific collaboration among the founder members coming from Holland and Italy there was a growing consensus to activate a philosophical doctorate (PhD) program, involving young Italian researchers in the field of perinatal medicine, neonatology and pediatrics. The aims were to promote excellence in research, offering to young Italian physicians the opportunity to maturate an International research experience leading to PhD degree, and to promote human and technological improvement energies in perinatal, neonatal and pediatrics research. Thus, an official collaboration among the Dutch Universities from Maastricht and Utrecht and the Italian Children's Hospital from Alessandria, has been activated on March 1st 2010, finalized to the PhD program. The experimental phase included the selection of projects and relative candidates after an interview-selection focusing on their scientific attitudes and the availability on their research projects. Candidates' selection started on May 2010 and on September 29th ten projects and candidates have been approved by the scientific commission. Research topics included: perinatal asphyxia, aging and the origin of adulthood neurodegenerative disease, neuroprotective strategies, biochemical pulmonology, intrauterine growth retardation and perinatal teratology. To date, all projects have been approved by local Ethics Committee from the University/Hospital of origin of the candidates. Five manuscripts have been published and/or submitted to international Journals regarding pneumology, perinatal asphyxia and teratology, whilst about 60-70% of data regarding clinical studies have already been collected.

  19. The Third Force in Folklore Studies: Gary Alan Fine's Sociological Approach

    Directory of Open Access Journals (Sweden)

    Dragana Antonijević

    2016-03-01

    Full Text Available This paper attempts to offer a critical overview of the theoretical and methodological contribution of micro-sociologist and social psychologist Gary Alan Fine to folklore studies. It begins with a discussion of both the major and most questioned points of his methodology, continues with a consideration of the wider folkloristical framework of his interpretation, and ends with a suggestion for innovation and improvement of Fine's analytical framework for the interpretation of folk narratives. Gary Alan Fine's most significant contribution to folklore studies was research of rumours and urban legends, including their meaning, function, and influence on individual behavior. In a series of papers, apart from offering an interpretation of various urban and corporate legends, he also demonstrated methods and means of connecting social and cultural factors with narrative content, in the context of social and economic structures and relations in post-industrial and late-capitalist global societies. Of special interest are papers in which he analyzes folklore as expressive culture and a form of symbolic communication between small groups, as an important form of selfidentification and behavior strategies both from within and without of the group. Fine makes a point when he diagnoses a lack of analyses of this sort in American folklore studies, wishing there were enough to make a significant turn in contemporary folkloristics. This is why Fine named his new research strategy the "third force". Another dimension of his contribution is the further elaboration of the analytical framework that relies on socio-structural, socio-psychological, symbolical and economical parameters of explanation. For that purpose, he constructed a theoretical and methodogical model called the folklore diamond. With his suggestions and critique of the existing state of folklore studies, Gary Alan Fine provided a very significant contribution to the science of folklore in general.

  7. Alan Turing's electronic brain the struggle to build the ACE, the world's fastest computer

    CERN Document Server

    Copeland, B Jack

    2012-01-01

    The mathematical genius Alan Turing, now well known for his crucial wartime role in breaking the ENIGMA code, was the first to conceive of the fundamental principle of the modern computer-the idea of controlling a computing machine's operations by means of a program of coded instructions, stored in the machine's 'memory'. In 1945 Turing drew up his revolutionary design for an electronic computing machine-his Automatic Computing Engine ('ACE'). A pilot model of the ACE ran its firstprogram in 1950 and the production version, the 'DEUCE', went on to become a cornerstone of the fledgling British

  12. Structural insight into histone recognition by the ING PHD fingers.

    Science.gov (United States)

    Champagne, Karen S; Kutateladze, Tatiana G

    2009-05-01

    The Inhibitor of Growth (ING) tumor suppressors are implicated in oncogenesis, control of DNA damage repair, cellular senescence and apoptosis. All members of the ING family contain unique amino-terminal regions and a carboxy-terminal plant homeodomain (PHD) finger. While the amino-terminal domains associate with a number of protein effectors including distinct components of histone deacetylase (HDAC) and histone acetyltransferase (HAT) complexes, the PHD finger binds strongly and specifically to histone H3 trimethylated at lysine 4 (H3K4me3). In this review we describe the molecular mechanism of H3K4me3 recognition by the ING1-5 PHD fingers, analyze the determinants of the histone specificity and compare the biological activities and structures within subsets of PHD fingers. The atomic-resolution structures of the ING PHD fingers in complex with a H3K4me3 peptide reveal that the histone tail is bound in a large and deep binding site encompassing nearly one-third of the protein surface. An extensive network of intermolecular hydrogen bonds, hydrophobic and cation-pi contacts, and complementary surface interactions coordinate the first six residues of the H3K4me3 peptide. The trimethylated Lys4 occupies an elongated groove, formed by the highly conserved aromatic and hydrophobic residues of the PHD finger, whereas the adjacent groove accommodates Arg2. The two grooves are connected by a narrow channel, the small size of which defines the PHD finger's specificity, excluding interactions with other modified histone peptides. Binding of the ING PHD fingers to H3K4me3 plays a critical role in regulating chromatin acetylation. The ING proteins function as tethering molecules that physically link the HDAC and HAT enzymatic complexes to chromatin. In this review we also highlight progress recently made in understanding the molecular basis underlying biological and tumorigenic activities of the ING tumor suppressors.

  13. Robots testing robots: ALAN-Arm, a humanoid arm for the testing of robotic rehabilitation systems.

    Robotics is increasing in popularity as a method of providing rich, personalized and cost-effective physiotherapy to individuals with some degree of upper limb paralysis, such as those who have suffered a stroke. These robotic rehabilitation systems are often high powered, and exoskeletal systems can attach to the person in a restrictive manner. Therefore, ensuring the mechanical safety of these devices before they come in contact with individuals is a priority. Additionally, rehabilitation systems may use novel sensor systems to measure current arm position. Used to capture and assess patient movements, these first need to be verified for accuracy by an external system. We present the ALAN-Arm, a humanoid robotic arm designed to be used for both accuracy benchmarking and safety testing of robotic rehabilitation systems. The system can be attached to a rehabilitation device and then replay generated or human movement trajectories, as well as autonomously play rehabilitation games or activities. Tests of the ALAN-Arm indicated it could recreate the path of a generated slow movement path with a maximum error of 14.2mm (mean = 5.8mm) and perform cyclic movements up to 0.6Hz with low gain (<1.5dB). Replaying human data trajectories showed the ability to largely preserve human movement characteristics with slightly higher path length and lower normalised jerk.

  14. A Semiotic Analysis of Visual Elements Particular to the Medium of Comics in Alan Ford by Max Bunker and Magnus

    Directory of Open Access Journals (Sweden)

    Hrvoje Gržina

    2014-12-01

    Full Text Available This paper presents the results of a semiotic analysis of visual elements characteristic for the medium of comic books applied to the first seventy-five issues of the Croatian edition of Alan Ford. After a description of the cultural and historical framework, it analyzes individual signs in comics and different elements specific for expression in comic books in Western culture with the aim of exploring which of these signs are present in Alan Ford, and to what extent. The results show that the analyzed comic book is deeply rooted in the visual and literary Western tradition, and that it contains virtually all the characteristic elements of representation in comic books. However, the paper also concludes that certain iconic elements of the vocabulary of comics – i.e. onomatopoeic neologisms – are to a certain extent specific and typical only for Alan Ford.

  15. The Production Rate and Employment of Ph.D. Astronomers

    CERN Document Server

    Metcalfe, Travis S

    2007-01-01

    In an effort to promote self-regulation of the astronomy job market, I examine the supply of, and demand for, astronomers over time. On the supply side, I document the production rate of Ph.D. astronomers from 1970 to 2006 using the UMI Dissertation Abstracts database, along with data from other independent sources. I compare the long-term trends in Ph.D. production with federal astronomy research funding over the same time period, and I demonstrate that additional funding is correlated with higher subsequent Ph.D. production. On the demand side, I monitor the changing patterns of employment using statistics about the number and types of jobs advertised in the AAS Job Register from 1984 to 2006. Finally, I assess the sustainability of the job market by normalizing this demand by the annual Ph.D. production. The most recent data suggest that there are now annual advertisements for about one postdoctoral job, half a faculty job, and half a research/support position for every new domestic Ph.D. recipient in astr...

The most recent data suggest that there are now annual advertisements for about one postdoctoral job, half a faculty job, and half a research/support position for every new domestic Ph.D. recipient in astronomy and astrophysics. The average new astronomer might expect to hold up to 3 jobs before finding a steady position.

  18. Dido3 PHD Modulates Cell Differentiation and Division

    Directory of Open Access Journals (Sweden)

    Jovylyn Gatchalian

    2013-07-01

    Full Text Available Death Inducer Obliterator 3 (Dido3 is implicated in the maintenance of stem cell genomic stability and tumorigenesis. Here, we show that Dido3 regulates the expression of stemness genes in embryonic stem cells through its plant homeodomain (PHD finger. Binding of Dido3 PHD to histone H3K4me3 is disrupted by threonine phosphorylation that triggers Dido3 translocation from chromatin to the mitotic spindle. The crystal structure of Dido3 PHD in complex with H3K4me3 reveals an atypical aromatic-cage-like binding site that contains a histidine residue. Biochemical, structural, and mutational analyses of the binding mechanism identified the determinants of specificity and affinity and explained the inability of homologous PHF3 to bind H3K4me3. Together, our findings reveal a link between the transcriptional control in embryonic development and regulation of cell division.

  19. An analysis of Ph.D. examiners' reports in engineering

    2016-03-01

    In recent years, there have been increasing calls for an overall transformation of the nature of engineering Ph.D. programs and the way theses are assessed. There exists a need to understand the examination process to ensure the best quality outcome for candidates in engineering. The work we present in this paper uses data collected between 2003 and 2010 for a total of 1220 Australian Ph.D. theses by analysing examiner reports. Our analysis indicates that Ph.D. theses in engineering, N = 106, differ considerably from those in other fields in areas such as gender of candidates and examiners and the examiners' geographical location. We also found that assessment areas such as significance and contribution of the thesis, publications arising from the thesis, breadth, depth and recency of the literature review and communication and editorial correctness are areas in which the proportion of text of engineering examiners' comments differs significantly from other fields.

    2017-01-01

    What jobs do mid-career PhD physicists hold? In a first-ever study, we collected data in 2011 from over 1,500 physics PhD recipients from the classes of 1996, 1997, 2000, and 2001. About 45% of the physics PhD recipients in these classes immediately took jobs that were not temporary, and over 40% accepted postdocs. How does taking a postdoc affect mid-career employment? What is the relationship between first job (after any postdocs) and mid-career employment? How do physicists' actual jobs compare with what they thought they would be doing when they graduated? Using our initial employment and mid-career data, I will answer these questions and more.

  1. Enhancing the skills of PhD supervisors facing internationalization

    DEFF Research Database (Denmark)

    Bøgelund, Pia

    2013-01-01

    This research started out due to some institutional changes at a department at Aalborg University as regards supervision of PhD students. For various reasons the department suddenly got a large intake of PhD students in 2008, many of which came with an international background. After a period...... of time staff members of the department began to look very frustrated. Not only did they feel burdened with the large intake, they also struggled with the task of facilitating the transition of international students to become independent scholars. The situation led to the creation of a more general...... interview study within the faculty, and an inquiry into the field of cross-cultural supervision with the purpose of enhancing the skills of PhD supervisors. As is often the case with cross-cultural exchange and inquiry, the study ended up by being just as informative on the supervision cultures and settings...

  2. Hydrogen release from sodium alanate observed by time-resolved neutron backscattering.

    2011-06-29

    Innermolecular motion in Na(3)AlH(6) gives rise to a Lorentzian spectrum with a wavenumber-independent width of about 1  µeV at 180 °C, which is probably due to the rotation of AlH(6) tetrahedra. There is no such quasielastic line in NaAlH(4) or NaH. Based on this finding, time-resolved measurements on the neutron backscattering spectrometer SPHERES were used to monitor the decomposition kinetics of sodium alanate, [Formula: see text] NaH. Both reaction steps were found to be accelerated by autocatalysis, most likely at the surfaces of Na(3)AlH(6) and NaH crystallites.

  4. Alan Strange as an adolescent: a discussion of Peter Shaffer's Equus.

    Science.gov (United States)

    Glenn, J

    1976-01-01

    Psychoanalytic knowledge of adolescence helps us to understand the protagonists of Peter Shaffer's play Equus. Alan Strang, the seventeen-year-old who maimed six horses, had undergone a retreat from oedipal wishes to narcissism typical of teenagers. His fragile attempts at achieving a sound sense of identity are undermined when his seeking of a noninestuous object produces panic and impotence. Dr. Dysart, the psychiatrist who envies his patient's passion, and fears hurting him through treatment, displays in an exaggerated way countertransferences often seen in therapists of adolescents. In addition, his doubts have some foundation in that the treatment he employs, catharsis, can encourage primitive defenses and the outpouring of uncontrolled, unneutralized drive derivatives. This is more likely to prevent adaptive creativity than the cure the doctor dreads. Finally, some technical problems in dealing with sublimations in psychoanalysis (which is not Dr. Dysart's form of treatment) are discussed.

    Full Text Available This article presents the first author's experiences as an Australian doctoral student undertaking a PhD by publication in the arena of the social sciences. She published nine articles in refereed journals and a peer-reviewed book chapter during the course of her PhD. We situate this experience in the context of current discussion about doctoral publication practices, in order to inform both postgraduate students and academics in general. The article discusses recent thinking about PhD by publication and identifies the factors that students should consider prior to adopting this approach, in terms of university requirements, supervisors' attitudes, the research subject matter, intellectual property, capacity and working style, and issues of co-authorship. It then outlines our perceptions of the advantages and disadvantages of undertaking a PhD by publication. We suggest that, in general, the advantages outweigh the disadvantages. We conclude by reflecting on how the first author's experiences relate to current discussions about fostering publications by doctoral students.

  3. The Society of Brains: How Alan Turing and Marvin Minsky Were Both Right

    Struzik, Zbigniew R.

    2015-04-01

    In his well-known prediction, Alan Turing stated that computer intelligence would surpass human intelligence by the year 2000. Although the Turing Test, as it became known, was devised to be played by one human against one computer, this is not a fair setup. Every human is a part of a social network, and a fairer comparison would be a contest between one human at the console and a network of computers behind the console. Around the year 2000, the number of web pages on the WWW overtook the number of neurons in the human brain. But these websites would be of little use without the ability to search for knowledge. By the year 2000 Google Inc. had become the search engine of choice, and the WWW became an intelligent entity. This was not without good reason. The basis for the search engine was the analysis of the ’network of knowledge’. The PageRank algorithm, linking information on the web according to the hierarchy of ‘link popularity’, continues to provide the basis for all of Google's web search tools. While PageRank was developed by Larry Page and Sergey Brin in 1996 as part of a research project about a new kind of search engine, PageRank is in its essence the key to representing and using static knowledge in an emergent intelligent system. Here I argue that Alan Turing was right, as hybrid human-computer internet machines have already surpassed our individual intelligence - this was done around the year 2000 by the Internet - the socially-minded, human-computer hybrid Homo computabilis-socialis. Ironically, the Internet's intelligence also emerged to a large extent from ‘exploiting’ humans - the key to the emergence of machine intelligence has been discussed by Marvin Minsky in his work on the foundations of intelligence through interacting agents’ knowledge. As a consequence, a decade and a half decade into the 21st century, we appear to be much better equipped to tackle the problem of the social origins of humanity - in particular thanks to the

    Well defined secondary structure motifs (e.g., helices) in polypeptides can be systematically studied in vacuo, offering a unique ``clean room" condition to quantify the stabilizing intramolecular interactions. Here we address theoretically the structure of alanine polypeptides Ac-Alan-LysH^+ (n=5,10,15), for which gas-phase helical structure was indicated in experiment [1]. Using van der Waals (vdW) corrected [2] Density Functional Theory (DFT), we present vibrational spectra and compare to room temperature multiple photon IR spectroscopy data obtained at the FELIX free electron laser. For the longer molecules (n=10,15) α-helical models provide good qualitative agreement (theory vs. experiment) already in the harmonic approximation. For Ac-Ala5LysH^+, the predicted lowest energy conformer (``g-1'') in vdW corrected DFT (PBE, B3LYP, revPBE) is not a simple helix. However, the harmonic free energy suggests that g-1 and the lowest-energy α-helical conformers are energetically close at 300 K, and thus might all coexist in experiment. Consistently, their calculated vibrational spectra agree with experiment, but only if anharmonic effects are included by explicit molecular dynamics simulations. [1] R.

    2015-06-01

    The super acidity of the unsolvated Al(C6F5)3 enabled isolation of the elusive silane-alane complex [Si-H⋅⋅⋅Al], which was structurally characterized by spectroscopic and X-ray diffraction methods. The Janus-like nature of this adduct, coupled with strong silane activation, effects multifaceted frustrated-Lewis-pair-type catalysis. When compared with the silane-borane system, the silane-alane system offers unique features or clear advantages in the four types of catalytic transformations examined in this study, including: ligand redistribution of tertiary silanes into secondary and quaternary silanes, polymerization of conjugated polar alkenes, hydrosilylation of unactivated alkenes, and hydrodefluorination of fluoroalkanes.

  8. Soybean GmPHD-type transcription regulators improve stress tolerance in transgenic Arabidopsis plants.

    Directory of Open Access Journals (Sweden)

    Wei Wei

    Full Text Available BACKGROUND: Soybean [Glycine max (L. Merr.] is one of the most important crops for oil and protein resource. Improvement of stress tolerance will be beneficial for soybean seed production. PRINCIPAL FINDINGS: Six GmPHD genes encoding Alfin1-type PHD finger protein were identified and their expressions differentially responded to drought, salt, cold and ABA treatments. The six GmPHDs were nuclear proteins and showed ability to bind the cis-element "GTGGAG". The N-terminal domain of GmPHD played a major role in DNA binding. Using a protoplast assay system, we find that GmPHD1 to GmPHD5 had transcriptional suppression activity whereas GmPHD6 did not have. In yeast assay, the GmPHD6 can form homodimer and heterodimer with the other GmPHDs except GmPHD2. The N-terminal plus the variable regions but not the PHD-finger is required for the dimerization. Transgenic Arabidopsis plants overexpressing the GmPHD2 showed salt tolerance when compared with the wild type plants. This tolerance was likely achieved by diminishing the oxidative stress through regulation of downstream genes. SIGNIFICANCE: These results provide important clues for soybean stress tolerance through manipulation of PHD-type transcription regulator.

  12. Critical issues in PhD training for biomedical scientists.

    Science.gov (United States)

    Juliano, R L; Oxford, G S

    2001-10-01

    The rapidly changing world of modern biomedical research is raising important new issues for traditional PhD training programs and is creating concern among young PhD scientists about their futures. Specifically, the United States is producing substantially more biomedical PhDs than can be accommodated in professional positions that truly require the PhD as a credential. The "surplus" PhD population is being relegated to poorly paid, unstable, and increasingly unsatisfying jobs. In addition, many current graduate and postdoctoral training programs may not be adequately preparing young scientists for the more complex, more quantitative biological science of the future. Finally, many current graduate training programs are not attracting a sufficient portion of the most talented young people in the nation. To ameliorate these problems in the training and early career paths of basic biomedical scientists, the authors make specific recommendations, such as urging (1) that graduate trainees should be supported exclusively by competitive individual fellowships, training grants, or institutional funds and not by RO1s or similar research awards; (2) that graduate and postdoctoral stipends be increased so that they provide a reasonable living wage; and (3) that research-intensive academic institutions create a career path for biomedical PhDs other than that designed for the traditional tenure-track, grant-funded principal investigator and faculty member. They conclude that it is in the interest of faculty and institutions to make these and other drastic changes because the current system is both inherently unfair and self-destructive.

  13. The multisensor PHD filter: II. Erroneous solution via Poisson magic

    Science.gov (United States)

    Mahler, Ronald

    2009-05-01

    The theoretical foundation for the probability hypothesis density (PHD) filter is the FISST multitarget differential and integral calculus. The "core" PHD filter presumes a single sensor. Theoretically rigorous formulas for the multisensor PHD filter can be derived using the FISST calculus, but are computationally intractable. A less theoretically desirable solution-the iterated-corrector approximation-must be used instead. Recently, it has been argued that an "elementary" methodology, the "Poisson-intensity approach," renders FISST obsolete. It has further been claimed that the iterated-corrector approximation is suspect, and in its place an allegedly superior "general multisensor intensity filter" has been proposed. In this and a companion paper I demonstrate that it is these claims which are erroneous. The companion paper introduces formulas for the actual "general multisensor intensity filter." In this paper I demonstrate that (1) the "general multisensor intensity filter" fails in important special cases; (2) it will perform badly in even the easiest multitarget tracking problems; and (3) these rather serious missteps suggest that the "Poisson-intensity approach" is inherently faulty.

  14. The Cancer Cell Oxygen Sensor PHD2 Promotes Metastasis via Activation of Cancer-Associated Fibroblasts

    Directory of Open Access Journals (Sweden)

    Anna Kuchnio

    2015-08-01

    Full Text Available Several questions about the role of the oxygen sensor prolyl-hydroxylase 2 (PHD2 in cancer have not been addressed. First, the role of PHD2 in metastasis has not been studied in a spontaneous tumor model. Here, we show that global PHD2 haplodeficiency reduced metastasis without affecting tumor growth. Second, it is unknown whether PHD2 regulates cancer by affecting cancer-associated fibroblasts (CAFs. We show that PHD2 haplodeficiency reduced metastasis via two mechanisms: (1 by decreasing CAF activation, matrix production, and contraction by CAFs, an effect that surprisingly relied on PHD2 deletion in cancer cells, but not in CAFs; and (2 by improving tumor vessel normalization. Third, the effect of concomitant PHD2 inhibition in malignant and stromal cells (mimicking PHD2 inhibitor treatment is unknown. We show that global PHD2 haplodeficiency, induced not only before but also after tumor onset, impaired metastasis. These findings warrant investigation of PHD2’s therapeutic potential.

    2004-05-01

    Leonard F. Peltier, MD, PhD, was an orthopaedic surgeon, academician, administrator, laboratory investigator, historian, and mentor. His career spanned nearly six decades, beginning with graduate education at the University of Minnesota (UM) under the auspices of Owen H. Wangensteen, MD, PhD. In addition to obtaining a PhD in physiology in the UM Graduate School, he completed general and orthopaedic surgery residencies and attained board certification in each specialty. He served in the US Army Occupation Force Medical Corps in Germany just after World War II. In 1957, at 37 years old, he assumed the chairmanship of the orthopaedic training program at the University of Kansas. In 1971, he couldn't resist the opportunity to become one of the founding members of the "start-up" University of Arizona College of Medicine, accepting an appointment as chair of the new orthopaedic training program, where he remained until his retirement in 1990. He took clinical problems to the laboratory, and made important scientific contributions, particularly in the area of fat embolism and in using calcium sulfate (plaster of Paris) to fill bone defects. He served on governing boards of national professional organizations and presided over the American Association for the Surgery of Trauma from 1980-1981. Throughout his career, he was fascinated by, and published extensively in, the history of medicine arena. Known fondly as "the professor" to many of his residents and colleagues, he had a pragmatic, honest, upbeat, and often humorous approach to life's challenges, valuing personal integrity above other virtues. He explored various eclectic interests far beyond his professional contributions while maintaining his family as a central priority. With his exemplary productivity and interests in the surgical and laboratory sciences, history of medicine, appreciation of fine arts, and perceptive and effective interactions with family, friends, patients, and colleagues, the memory of Leonard

    This study is a component of a four-year investigation of MS PHD'S Professional Development Program's virtual community through the lenses of underrepresented minority students in Earth system science and engineering fields. In this presentation, the development, assessment and projected utilization of the ongoing study will be discussed. The overall goal of this study is to examine the effectiveness of virtual team building methods and understand how the development of a communal cyberinfrastructure acts as an integral part of the emergence of a Scientific Renaissance. The exemplar, Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S), provides professional development experiences to facilitate the advancement of students of color achieving outstanding Earth system careers. Undergraduate and graduate students are supported through access to scientific conferences, mentorship and virtual community building. Framed by critical theory, this ethnographic exploration uses a mixed methods research design to record, observe, and analyze both the processes and products of the website, listserv and synchronous web-based dialogue. First, key findings of the formative evaluation and annual reports of the successfully implemented 2003 MS PHD'S Pilot Project are presented. These findings inform future evaluations of the use of technological resources and illustrate how this public space provides peer support and enriched research opportunities. Quantitative methods such as statistical analysis, academic and professional tracking and evaluative tools for scientific content and competency are complimented by qualitative methods that include observations, heuristic case studies and focus group interviews. The findings of this ongoing investigation will provide insight on how national organizations, higher education practitioners, community-based support systems and underrepresented minorities in the sciences promote diversity by developing

  3. Exploring PHD fingers and H3K4me0 interactions with molecular dynamics simulations and binding free energy calculations: AIRE-PHD1, a comparative study.

    Directory of Open Access Journals (Sweden)

    Dimitrios Spiliotopoulos

    Full Text Available PHD fingers represent one of the largest families of epigenetic readers capable of decoding post-translationally modified or unmodified histone H3 tails. Because of their direct involvement in human pathologies they are increasingly considered as a potential therapeutic target. Several PHD/histone-peptide structures have been determined, however relatively little information is available on their dynamics. Studies aiming to characterize the dynamic and energetic determinants driving histone peptide recognition by epigenetic readers would strongly benefit from computational studies. Herein we focus on the dynamic and energetic characterization of the PHD finger subclass specialized in the recognition of histone H3 peptides unmodified in position K4 (H3K4me0. As a case study we focused on the first PHD finger of autoimmune regulator protein (AIRE-PHD1 in complex with H3K4me0. PCA analysis of the covariance matrix of free AIRE-PHD1 highlights the presence of a "flapping" movement, which is blocked in an open conformation upon binding to H3K4me0. Moreover, binding free energy calculations obtained through Molecular Mechanics/Poisson-Boltzmann Surface Area (MM/PBSA methodology are in good qualitative agreement with experiments and allow dissection of the energetic terms associated with native and alanine mutants of AIRE-PHD1/H3K4me0 complexes. MM/PBSA calculations have also been applied to the energetic analysis of other PHD fingers recognizing H3K4me0. In this case we observe excellent correlation between computed and experimental binding free energies. Overall calculations show that H3K4me0 recognition by PHD fingers relies on compensation of the electrostatic and polar solvation energy terms and is stabilized by non-polar interactions.

    Mutations in autoimmune regulator (AIRE) gene cause autoimmune polyendocrinopathy candidiasis ectodermal dystrophy. AIRE is expressed in thymic medullary epithelial cells, where it promotes the expression of peripheral-tissue antigens to mediate deletional tolerance, thereby preventing self-reactivity. AIRE contains two plant homeodomains (PHDs) which are sites of pathological mutations. AIRE-PHD fingers are important for AIRE transcriptional activity and presumably play a crucial role in the formation of multimeric protein complexes at chromatin level which ultimately control immunological tolerance. As a step forward the understanding of AIRE-PHD fingers in normal and pathological conditions, we investigated their structure and used a proteomic SILAC approach to assess the impact of patient mutations targeting AIRE-PHD fingers. Importantly, both AIRE-PHD fingers are structurally independent and mutually non-interacting domains. In contrast to D297A and V301M on AIRE-PHD1, the C446G mutation on AIRE-PHD2 destroys the structural fold, thus causing aberrant AIRE localization and reduction of AIRE target genes activation. Moreover, mutations targeting AIRE-PHD1 affect the formation of a multimeric protein complex at chromatin level. Overall our results reveal the importance of AIRE-PHD domains in the interaction with chromatin-associated nuclear partners and gene regulation confirming the role of PHD fingers as versatile protein interaction hubs for multiple binding events.

    2016-01-01

    Many resources are invested in research training, but very little literature exists on predictors for a successful PhD and postdoctoral training outcome. A PhD program has two overall objectives: to extend knowledge about a hopefully important health topic and to provide extensive training to improve the PhD student's skills through learning research methods and collaboration. A substantial number of PhD students may run into some kind of problem in the course of their PhD program. In this article, some determinants all starting with an "I" and indicative of a good PhD outcome are reported. The successful PhD student can be described as having an Interest in the PhD program, an Incentive for the program, and an Idea of what he or she wants to investigate, showing Initiative, and having high personal Integrity and good Interpersonal relationships. When these so-called I-determinants are present, the likelihood of success in a PhD program is high. More evidence is available for selection of candidates for postdoctoral appointments since it is known that the postdoctoral candidate has completed a PhD program, published papers in peer-reviewed journals, and received awarded grants. However, other characteristics determine a successful transition of the postdoctoral candidate into a research leader. These determinants are Identity, Independence and Image, Implementation ability in terms of being able to implement decisions and projects, working with Innovative and Important topics, having In-depth knowledge of the research topic, being Interactive and Integrated with the scientific community, and Internationally oriented. In conclusion, regardless of the framework of research, the personal characteristics of a researcher play a very important role in the quality of research. Application of some of the principles mentioned in this article might allow decision to reach a more evidence-based way to recruit PhD students and postdoctorals.

    In 2011 the Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S)® initiative launched its newest activity entitled the MS PHD'S "Beyond the PhD (B-PhD) Professional Development Program." This exciting new program was designed to facilitate the development of a new community of underrepresented minority (URM) doctoral candidates and recent doctorate degree recipients in Earth system science (ESS)-related fields. The MS PHD'S B-PhD provides customized support and advocacy for MS PHD'S B-PhD participants in order to facilitate smoother and informed transitions from graduate school, to postdoctoral and tenure-track positions, as well as other "first" jobs in government, industry, and non-profit organizations. In November 2011 the first cohort of MS PHD'S B-PhD participants engaged in intensive sessions on the following topics: "Toolkits for Success for Academia, Business/Industry, Federal Government and Non-Profits", "Defining Short, Mid and Long Term Career Goals", "Accessing and Refining Skill Sets and Other Door Openers", "International Preparation and Opportunities", "Paying it Forward/Lifting as You Climb", and "Customized Strategies for Next Steps". This pilot event, which was hosted by the University of Texas at Arlington's (UTA) College of Science, also provided opportunities for participants to serve as guest lecturers in the UTA's Colleges of Science and Engineering and included one-on-one discussions with MS PHD'S B-PhD mentors and guest speakers who are well established within their individual ESS fields. Insights regarding opportunities, challenges and obstacles commonly faced by URMs within the ESS fields, as well as strategies for success were shared by MS PHD'S B-PhD mentors and guest speakers. Survey results indicate that MS PHD'S B-PhD participants appreciated not only the material covered during this pilot activity, but also appreciated the opportunity to become part of a community of young URM ESS

  16. PHD2: from hypoxia regulation to disease progression.

    Science.gov (United States)

    Meneses, Ana M; Wielockx, Ben

    2016-01-01

    Oxygen represents one of the major molecules required for the development and maintenance of life. An adequate response to hypoxia is therefore required for the functioning of the majority of living organisms and relies on the activation of the hypoxia-inducible factor (HIF) pathway. HIF prolyl hydroxylase domain-2 (PHD2) has long been recognized as the major regulator of this response, controlling a myriad of outcomes that range from cell death to proliferation. However, this enzyme has been associated with more pathways, making the role of this protein remarkably complex under distinct pathologies. While a protective role seems to exist in physiological conditions such as erythropoiesis; the picture is more complex during pathologies such as cancer. Since the regulation of this enzyme and its closest family members is currently considered as a possible therapy for various diseases, understanding the different particular roles of this protein is essential.

    These are notes of a talk I gave in a seminar at the University of Pennsylvania summarizing results in the Ph.D. thesis of Michael Mueter obtained under the direction of Wolfgang Meyer at the University of Muenster. His thesis on "Kruemmungserhoehende Deformationen mittels Gruppenaktionen" examines in detail curvature properties of so called Cheeger deformations. Such deformations have been a crucial ingredient in non-negative and positive curvature constructions. His thesis contains a wealth of interesting properties of such deformations, but since it was never published, is only known to a few experts. I have no intention to publish these notes, but post them as a service to the public. A scanned version of his thesis (written in German) is available on my homepage.

  2. The Oxygen Sensor PHD2 Controls Dendritic Spines and Synapses via Modification of Filamin A

    Inmaculada Segura

    2016-03-01

    Full Text Available Neuronal function is highly sensitive to changes in oxygen levels, but how hypoxia affects dendritic spine formation and synaptogenesis is unknown. Here we report that hypoxia, chemical inhibition of the oxygen-sensing prolyl hydroxylase domain proteins (PHDs, and silencing of Phd2 induce immature filopodium-like dendritic protrusions, promote spine regression, reduce synaptic density, and decrease the frequency of spontaneous action potentials independently of HIF signaling. We identified the actin cross-linker filamin A (FLNA as a target of PHD2 mediating these effects. In normoxia, PHD2 hydroxylates the proline residues P2309 and P2316 in FLNA, leading to von Hippel-Lindau (VHL-mediated ubiquitination and proteasomal degradation. In hypoxia, PHD2 inactivation rapidly upregulates FLNA protein levels because of blockage of its proteasomal degradation. FLNA upregulation induces more immature spines, whereas Flna silencing rescues the immature spine phenotype induced by PHD2 inhibition.

    Fuse, T.; Hiramatsu, D.; Nakanishi, W.

    2016-06-01

    We propose a new technique to detect multiple targets from full-waveform airborne laser scanner. We introduce probability hypothesis density (PHD) filter, a type of Bayesian filtering, by which we can estimate the number of targets and their positions simultaneously. PHD filter overcomes some limitations of conventional Gaussian decomposition method; PHD filter doesn't require a priori knowledge on the number of targets, assumption of parametric form of the intensity distribution. In addition, it can take a similarity between successive irradiations into account by modelling relative positions of the same targets spatially. Firstly we explain PHD filter and particle filter implementation to it. Secondly we formulate the multi-target detection problem on PHD filter by modelling components and parameters within it. At last we conducted the experiment on real data of forest and vegetation, and confirmed its ability and accuracy.

  5. Prolyl-4-hydroxylase 3 (PHD3 expression is downregulated during epithelial-to-mesenchymal transition.

    Directory of Open Access Journals (Sweden)

    Trenton L Place

    Full Text Available Prolyl-4-hydroxylation by the intracellular prolyl-4-hydroxylase enzymes (PHD1-3 serves as a master regulator of environmental oxygen sensing. The activity of these enzymes is tightly tied to tumorigenesis, as they regulate cell metabolism and angiogenesis through their control of hypoxia-inducible factor (HIF stability. PHD3 specifically, is gaining attention for its broad function and rapidly accumulating array of non-HIF target proteins. Data from several recent studies suggest a role for PHD3 in the regulation of cell morphology and cell migration. In this study, we aimed to investigate this role by closely examining the relationship between PHD3 expression and epithelial-to-mesenchymal transition (EMT; a transcriptional program that plays a major role in controlling cell morphology and migratory capacity. Using human pancreatic ductal adenocarcinoma (PDA cell lines and Madin-Darby Canine Kidney (MDCK cells, we examined the correlation between several markers of EMT and PHD3 expression. We demonstrated that loss of PHD3 expression in PDA cell lines is highly correlated with a mesenchymal-like morphology and an increase in cell migratory capacity. We also found that induction of EMT in MDCK cells resulted in the specific downregulation of PHD3, whereas the expression of the other HIF-PHD enzymes was not affected. The results of this study clearly support a model by which the basal expression and hypoxic induction of PHD3 is suppressed by the EMT transcriptional program. This may be a novel mechanism by which migratory or metastasizing cells alter signaling through specific pathways that are sensitive to regulation by O2. The identification of downstream pathways that are affected by the suppression of PHD3 expression during EMT may provide important insight into the crosstalk between O2 and the migratory and metastatic potential of tumor cells.

  7. Epidermal or dermal specific knockout of PHD-2 enhances wound healing and minimizes ischemic injury.

    Directory of Open Access Journals (Sweden)

    Andrew S Zimmermann

    Full Text Available INTRODUCTION: Hypoxia-inducible factor (HIF-1α, part of the heterodimeric transcription factor that mediates the cellular response to hypoxia, is critical for the expression of multiple angiogenic growth factors, cell motility, and the recruitment of endothelial progenitor cells. Inhibition of the oxygen-dependent negative regulator of HIF-1α, prolyl hydroxylase domain-2 (PHD-2, leads to increased HIF-1α and mimics various cellular and physiological responses to hypoxia. The roles of PHD-2 in the epidermis and dermis have not been clearly defined in wound healing. METHODS: Epidermal and dermal specific PHD-2 knockout (KO mice were developed in a C57BL/6J (wild type background by crossing homozygous floxed PHD-2 mice with heterozygous K14-Cre mice and heterozygous Col1A2-Cre-ER mice to get homozygous floxed PHD-2/heterozygous K14-Cre and homozygous floxed PHD-2/heterozygous floxed Col1A2-Cre-ER mice, respectively. Ten to twelve-week-old PHD-2 KO and wild type (WT mice were subjected to wounding and ischemic pedicle flap model. The amount of healing was grossly quantified with ImageJ software. Western blot and qRT-PCR was run on protein and RNA from primary cells cultured in vitro. RESULTS: qRT-PCR demonstrated a significant decrease of PHD-2 in keratinocytes and fibroblasts derived from tissue specific KO mice relative to control mice (*p<0.05. Western blot analysis showed a significant increase in HIF-1α and VEGF protein levels in PHD-2 KO mice relative to control mice (*p<0.05. PHD-2 KO mice showed significantly accelerated wound closure relative to WT (*p<0.05. When ischemia was analyzed at day nine post-surgery in a flap model, the PHD-2 tissue specific knockout mice showed significantly more viable flaps than WT (*p<0.05. CONCLUSIONS: PHD-2 plays a significant role in the rates of wound healing and response to ischemic insult in mice. Further exploration shows PHD-2 KO increases cellular levels of HIF-1α and this increase leads to the

    Full Text Available Besides teaching, research is one of the main activities of the Faculty of Medicine of the University of Ljubljana. Since 1995, the PhD study at the Faculty of Medicine has been organized via the Biomedicine university programme. The authors performed the analysis of the quality of Biomedicine PhD study at the Faculty of Medicine between the years 1995 and 2010. The authors were interested in the number of PhD students that started and finished their PhD studies and how successful PhD students were during that period (how many papers they wrote on the topic of the PhD and what was the impact factor of the papers. In the 15-year period from 1995–2010, 702 students started the Biomedicine PhD programme, while 652 students completed it. Most PhD students (70.7 % have written one SCI paper related to the thesis. Finally, the medium impact factor of the SCI paper related to the PhD thesis was 2.6. We may conclude that the quality of PhD theses evaluated according to the impact factor of the SCI papers related to the theses is solid, however our strength should be aimed toward the continuous increase of quality. In this regard, PhD candidates, mentors as well as the commission for the evaluation of PhD theses must do their homework diligently.

    Aluminium nitride (AlN) films grown with dimethylethylamine alane (DMEAA) are compared with the ones grown with trimethylaluminium (TMA). In the high-resolution x-ray diffraction Ω scans, the full width at half maximum (FWHM) of (0002) AlN films grown with DMEAA is about 0.70 deg, while the FWHM of (0002)AlN films grown with TMA is only 0.11 deg. The surface morphologies of the films are different, and the rms roughnesses of the surface are approximately identical. The rms roughness of AlN films grown with DMEAA is 47.4 nm, and grown with TMA is 69.4 nm. Although using DMEAA as the aluminium precursor cannot improve the AlN crystal quality, AlN growth can be reached at low temperature of 673 K. Thus, DMEAA is an alternative aluminium precursor to deposit AlN film at low growth temperatures.

    Safe and efficient hydrogen storage is a significant challenge inhibiting the use of hydrogen as a primary energy carrier. Although energy storage performance properties are critical to the success of solid-state hydrogen storage systems, operator and user safety is of highest importance when designing and implementing consumer products. As researchers are now integrating high energy density solid materials into hydrogen storage systems, quantification of the hazards associated with the operation and handling of these materials becomes imperative. The experimental effort presented in this paper focuses on identifying the hazards associated with producing, storing, and handling sodium alanates, and thus allowing for the development and implementation of hazard mitigation procedures. The chemical changes of sodium alanates associated with exposure to oxygen and water vapor have been characterized by thermal decomposition analysis using simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS) and X-ray diffraction methods. Partial oxidation of sodium alanates, an alkali metal complex hydride, results in destabilization of the remaining hydrogen-containing material. At temperatures below 70 C, reaction of sodium alanate with water generates potentially combustible mixtures of H{sub 2} and O{sub 2}. In addition to identifying the reaction hazards associated with the oxidation of alkali-metal containing complex hydrides, potential treatment methods are identified that chemically stabilize the oxidized material and reduce the hazard associated with handling the contaminated metal hydrides.

    1997-06-01

    In the early 1980s several prominent scientists left the hallowed halls of respected universities seeking to exploit the revolution occurring in biology in an environment devoid of the bureaucratic and political confines of academia. The emergence of the biotechnology industry has been marked by both spectacular failures and success stories. Genentech was founded in 1976 by biochemist Herbert Boyer and venture capitalist Robert Swanson and went public in 1980. In 1995 Genentech merged with Roche Holdings Ltd., of Basel Switzerland. Distinguished from other biotech companies by the varied array of products it has brought to market, Genentech has also developed a unique corporate culture embodying many traditional academic values. Just as Genentech went public in 1980, Arthur D. Levinson, PhD, finished a post-doctoral appointment in Michael Bishop's lab at the University of California, San Francisco. Despite the disapproval of colleagues, he joined the fledgling company as a senior scientist. Working his way though the ranks, Levinson became Vice President of Research Technology in 1989 and was named President and CEO in 1995. Interviewed at the sprawling corporate headquarters in South San Francisco, Levinson reflected on the process of high risk science, the benefits of the private sector, and the changing relationship between biotech companies and the academic world.

    In this paper, an improved nonlinear Gaussian mixture probability hypothesis density (GM-PHD) filter is proposed to address bearings-only measurements in multi-target tracking. The proposed method, called the Gaussian mixture measurements-probability hypothesis density (GMM-PHD) filter, not only approximates the posterior intensity using a Gaussian mixture, but also models the likelihood function with a Gaussian mixture instead of a single Gaussian distribution. Besides, the target birth model of the GMM-PHD filter is assumed to be partially uniform instead of a Gaussian mixture. Simulation results show that the proposed filter outperforms the GM-PHD filter embedded with the extended Kalman filter (EKF) and the unscented Kalman filter (UKF). PMID:27626423

    Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomic autoimmune disease resulting from the defective function of a gene codifying for a transcription factor named autoimmune regulation (AIRE). The AIRE protein contains several domains among which two PHD fingers involved in the transcriptional activation. We investigated the function of the two PHD finger domains and the COOH terminal portion of AIRE by using several mutated constructs transfected in mammalian cells and a luciferase reporter assay. The results predict that the second PHD as well as the COOH terminal regions have marked transactivational properties. The COOH terminal region contains the fourth LXXLL and the PXXPXP motifs which play a critical role in mediating the transactivation capacity of the AIRE protein. Our study provides a definition of the role of the PHD fingers in transactivation and identifies a new transactivation domain of the AIRE protein localized in the COOH terminal region.

    Full Text Available globalization is changing the qualitative characteristics of society, affecting both the life and mentality of people. In relevance to globalization, higher education is gaining new dimensions as well. Bologna and Lisbon documents guide and obligate each country to create integrated and harmonious international space of higher education in Europe. phd studies are considered as integral in the higher education structure; therefore, internationalization is a significant imperative for phd studies development. In the process of internationalization, the need for students’ intercultural competencies is widely recognized. Firstly, we suppose that the impact of globalization on internationalization still remains underestimated. Globalization makes internationalization not only more intense, but also qualitatively different. Secondly, there is a lack of systemic analysis on the development of intercultural research competencies in phd studies. We relate the need for intercultural research competencies to the following critical and rhetorical question: ‘Are today’s phd students ready to solve tomorrow’s global problems?’

    evolutionary origin for the phd/doc operon. Doc induces growth arrest of Escherichia coli cells in a reversible manner, by targeting the protein synthesis machinery. Moreover, Doc activates the endogenous E. coli RelE mRNA interferase but does not require this or any other known chromosomal toxin......Prokaryotic toxin-antitoxin modules are involved in major physiological events set in motion under stress conditions. The toxin Doc (death on curing) from the phd/doc module on phage P1 hosts the C-terminal domain of its antitoxin partner Phd (prevents host death) through fold complementation....... This Phd domain is intrinsically disordered in solution and folds into an alpha-helix upon binding to Doc. The details of the interactions reveal the molecular basis for the inhibitory action of the antitoxin. The complex resembles the Fic (filamentation induced by cAMP) proteins and suggests a possible...

    Full Text Available In this paper, an improved nonlinear Gaussian mixture probability hypothesis density (GM-PHD filter is proposed to address bearings-only measurements in multi-target tracking. The proposed method, called the Gaussian mixture measurements-probability hypothesis density (GMM-PHD filter, not only approximates the posterior intensity using a Gaussian mixture, but also models the likelihood function with a Gaussian mixture instead of a single Gaussian distribution. Besides, the target birth model of the GMM-PHD filter is assumed to be partially uniform instead of a Gaussian mixture. Simulation results show that the proposed filter outperforms the GM-PHD filter embedded with the extended Kalman filter (EKF and the unscented Kalman filter (UKF.

    The Minorities Striving and Pursuing Higher Degrees of Success (MS PHD'S) Professional Development Program in Earth system science (ESS) is a model initiative for improving the retention of underrepresented minority (URM) students in STEM fields. Entering its ninth cohort, MS PHD'S remains committed to helping URM undergraduate and graduate students achieve outstanding careers in ESS. MS PHD'S facilitates URM student achievement through a three-phase program designed to increase student exposure to the ESS community. By engaging in a series of professional development and skill building exercises, peer-to-peer community building activities, participation in scientific society conferences and workshops, mentoring by URM and other scientists, and a virtual community, URM students gain the confidence and support necessary to achieve their academic goals and enter the ESS workforce. Since its inception, MS PHD'S continues to support 189 participants. Of these 189 participants, 35 have advanced from undergraduate and graduate academic pathways to completion of their PhD and another 60 are currently enrolled in doctoral programs. MS PHD'S maintains close ties with program alumni to further support retention, inclusivity, and broadening participation of URM students and graduates in STEM activities. Its model is built on reengaging alumni to become mentors and leaders for each new cohort as well as facilitating valuable opportunities for alumni to advance in their ESS related academic and professional career pathways.

    Sp140 is a nuclear leukocyte-specific protein involved in primary biliary cirrhosis and a risk factor in chronic lymphocytic leukemia. The presence of several chromatin related modules such as plant homeodomain (PHD), bromodomain and SAND domain suggests a role in chromatin-mediated regulation of gene expression; however, its real function is still elusive. Herein we present the solution structure of Sp140-PHD finger and investigate its role as epigenetic reader in vitro. Sp140-PHD presents an atypical PHD finger fold which does not bind to histone H3 tails but is recognized by peptidylprolyl isomerase Pin1. Pin1 specifically binds to a phosphopeptide corresponding to the L3 loop of Sp140-PHD and catalyzes cis-trans isomerization of a pThr-Pro bond. Moreover co-immunoprecipitation experiments demonstrate FLAG-Sp140 interaction with endogenous Pin1 in vivo. Overall these data include Sp140 in the list of the increasing number of Pin1 binders and expand the regulatory potential of PHD fingers as versatile structural platforms for diversified interactions. © 2013 FEBS.

  10. Solution NMR structure and histone binding of the PHD domain of human MLL5.

    Directory of Open Access Journals (Sweden)

    Alexander Lemak

    Full Text Available Mixed Lineage Leukemia 5 (MLL5 is a histone methyltransferase that plays a key role in hematopoiesis, spermatogenesis and cell cycle progression. In addition to its catalytic domain, MLL5 contains a PHD finger domain, a protein module that is often involved in binding to the N-terminus of histone H3. Here we report the NMR solution structure of the MLL5 PHD domain showing a variant of the canonical PHD fold that combines conserved H3 binding features from several classes of other PHD domains (including an aromatic cage along with a novel C-terminal α-helix, not previously seen. We further demonstrate that the PHD domain binds with similar affinity to histone H3 tail peptides di- and tri-methylated at lysine 4 (H3K4me2 and H3K4me3, the former being the putative product of the MLL5 catalytic reaction. This work establishes the PHD domain of MLL5 as a bone fide 'reader' domain of H3K4 methyl marks suggesting that it may guide the spreading or further methylation of this site on chromatin.

    Loss of prolyl hydroxylase 2 (PHD2) activates the hypoxia-inducible factor-dependent hypoxic response, including anaerobic glycolysis, which causes large amounts of lactate to be released from cells into the circulation. We found that Phd2-null mouse embryonic fibroblasts (MEFs) produced more lactate than wild-type MEFs, as expected, whereas systemic inactivation of PHD2 in mice did not cause hyperlacticacidemia. This unexpected observation led us to hypothesize that the hypoxic response activated in the liver enhances the Cori cycle, a lactate-glucose carbon recycling system between muscle and liver, and thereby decreases circulating lactate. Consistent with this hypothesis, blood lactate levels measured after a treadmill or lactate tolerance test were significantly lower in Phd2-liver-specific knockout (Phd2-LKO) mice than in control mice. An in vivo (13)C-labeled lactate incorporation assay revealed that the livers of Phd2-LKO mice produce significantly more glucose derived from (13)C-labeled lactate than control mice, suggesting that blockade of PHD2 in the liver ameliorates lactic acidosis by activating gluconeogenesis from lactate. Phd2-LKO mice were resistant to lactic acidosis induced by injection of a lethal dose of lactate, displaying a significant elongation of survival. Moreover, oral administration of a PHD inhibitor improved survival in an endotoxin shock mice model. These data suggest that PHD2 is a potentially novel drug target for the treatment of lactic acidosis, which is a serious and often fatal complication observed in some critically ill patients.

    Full Text Available In response to the important issues regarding diversity in business schools and corporate America, the KPMG Foundation established the PhD Project. The PhD Project helps business professionals and recent college graduates earn doctoral degrees in business disciplines and join business school faculty. While the PhD Project has helped increase the number of minority faculty members in business schools, it may be helpful to gather insights from the recent PhD alumni who have received support from the PhD Project. Our study examines attitudes about preparedness of PhD Project alums for their first faculty position after completing their PhD program. Results show that PhD Project alumni and majority PhD alumni (alumni not associated with the PhD Project felt they were prepared for their first faculty position, but they were not significantly different in their evaluation in most respects. However, to our surprise, majority PhD alumni felt they were better prepared for research than PhD Project alumni. This difference was significant and further analyses showed that younger faculty and those in the ethnic majority were better prepared for research. Both groups considered themselves well prepared for research and teaching. Neither group was as optimistic about being prepared for service responsibilities and the academic climate or politics of an academic career. Our findings show that the PhD Project is necessary to help ensure that minority faculty members are adequately prepared for research and their academic careers.

  16. Towards understanding a mechanism for reversible hydrogen storage: theoretical study of transition metal catalysed dehydrogenation of sodium alanate.

    Ljubić, Ivan; Clary, David C

    2010-04-28

    On the basis of density functional theory and coupled-cluster CCSD(T) calculations we propose a mechanism of the dehydrogenation of transition metal doped sodium alanate. Insertion of two early 3d-transition metals, scandium and titanium, both of which are promising catalysts for reversible hydrogen storage in light metal hydrides, is compared. The mechanism is deduced from studies on the decomposition of a model system consisting of one transition metal atom and two NaAlH(4) units. Subsequently, the significance of such minimal cluster model systems to the real materials is tested by embedding the systems into the surface of the NaAlH(4) crystal. It is found that the dehydrogenation proceeds via breaking of the bridge H-Al bond and consequent formation of intermediate coordination compounds in which the H(2) molecule is side-on (eta(2)-) bonded to the transition metal centre. The total barrier to the H(2) release is thus dependent upon both the strength of the Al-H bond to be broken and the depth of the coordinative potential. The analogous mechanism applies for the recognized three successive dehydrogenation steps. The gas-phase model structures embedded into the surface of the NaAlH(4) crystal exhibit an unambiguous kinetic stability and their general geometric features remain largely unchanged.

  17. A PHD-polycomb repressive complex 2 triggers the epigenetic silencing of FLC during vernalization.

    Vernalization, the acceleration of flowering by winter, involves cold-induced epigenetic silencing of Arabidopsis FLC. This process has been shown to require conserved Polycomb Repressive Complex 2 (PRC2) components including the Su(z)12 homologue, VRN2, and two plant homeodomain (PHD) finger proteins, VRN5 and VIN3. However, the sequence of events leading to FLC repression was unclear. Here we show that, contrary to expectations, VRN2 associates throughout the FLC locus independently of cold. The vernalization-induced silencing is triggered by the cold-dependent association of the PHD finger protein VRN5 to a specific domain in FLC intron 1, and this association is dependent on the cold-induced PHD protein VIN3. In plants returned to warm conditions, VRN5 distribution changes, and it associates more broadly over FLC, coincident with significant increases in H3K27me3. Biochemical purification of a VRN5 complex showed that during prolonged cold a PHD-PRC2 complex forms composed of core PRC2 components (VRN2, SWINGER [an E(Z) HMTase homologue], FIE [an ESC homologue], MSI1 [p55 homologue]), and three related PHD finger proteins, VRN5, VIN3, and VEL1. The PHD-PRC2 activity increases H3K27me3 throughout the locus to levels sufficient for stable silencing. Arabidopsis PHD-PRC2 thus seems to act similarly to Pcl-PRC2 of Drosophila and PHF1-PRC2 of mammals. These data show FLC silencing involves changed composition and dynamic redistribution of Polycomb complexes at different stages of the vernalization process, a mechanism with greater parallels to Polycomb silencing of certain mammalian loci than the classic Drosophila Polycomb targets.

    The main oxygen sensor hypoxia inducible factor (HIF) prolyl hydroxylase 2 (PHD2) is a critical regulator of tissue homeostasis during erythropoiesis, hematopoietic stem cell maintenance, and wound healing. Recent studies point toward a role for the PHD2-erythropoietin (EPO) axis in the modulation of bone remodeling, even though the studies produced conflicting results. Here, we used a number of mouse strains deficient of PHD2 in different cell types to address the role of PHD2 and its downstream targets HIF-1α and HIF-2α in bone remodeling. Mice deficient for PHD2 in several cell lineages, including EPO-producing cells, osteoblasts, and hematopoietic cells (CD68:cre-PHD2(f/f) ) displayed a severe reduction of bone density at the distal femur as well as the vertebral body due to impaired bone formation but not bone resorption. Importantly, using osteoblast-specific (Osx:cre-PHD2(f/f) ) and osteoclast-specific PHD2 knock-out mice (Vav:cre- PHD2(f/f) ), we show that this effect is independent of the loss of PHD2 in osteoblast and osteoclasts. Using different in vivo and in vitro approaches, we show here that this bone phenotype, including the suppression of bone formation, is directly linked to the stabilization of the α-subunit of HIF-2, and possibly to the subsequent moderate induction of serum EPO, which directly influenced the differentiation and mineralization of osteoblast progenitors resulting in lower bone density. Taken together, our data identify the PHD2:HIF-2α:EPO axis as a so far unknown regulator of osteohematology by controlling bone homeostasis. Further, these data suggest that patients treated with PHD inhibitors or EPO should be monitored with respect to their bone status. © 2016 American Society for Bone and Mineral Research.

    Full Text Available Introduction: Quality of research in PhD programs increases if supervisors become aware of students' expectations from them. This qualitative study aimed to explore expectations of PhD students from their supervisors was done.   Methods: This qualitative content analysis study was conducted on 22 graduated PhD students of Iran University of Medical Sciences, in 2014. The samples were purposefully selected and interviewed. All interviews were recorded and transcribed verbatim.   Results: After analyzing and coding data, it was found that PhD students have four main expectations from their supervisors. These expectations consist of scientific support including help with selection of subject, preparation and registration of proposal, data collection and support for writing and examination of the thesis. Developing scientific skills and help with preparing manuscripts were other expectations. Emotional-social support with five categories including relationship between supervisor-student, general expectations of supervisor, supervisor personality characteristics, needed emotional skills and social activities related to thesis and finally providing adequate resources including financial support and access to facilities inside and outside the university were among the other expectations.   Conclusion: PhD students need to scientific, emotional, social and material supports from their supervisors in the process of performing thesis. These expectations should be told to supervisors.

    Malaysian government has recently set a new goal to produce 60,000 Malaysian PhD holders by the year 2023. As a Malaysia's largest institution of higher learning in terms of size and population which offers more than 500 academic programmes in a conducive and vibrant environment, UiTM has taken several initiatives to fill up the gap. Strategies to increase the numbers of graduates with PhD are a process that is challenging. In many occasions, many have already identified that the struggle to get into the target set is even more daunting, and that implementation is far too ideal. This has further being progressing slowly as the attrition rate increases. This study aims to apply the proposed models that incorporates several factors in predicting the number PhD students that will complete their PhD studies on time. Binary Logistic Regression model is proposed and used on the set of data to determine the number. The results show that only 6.8% of the 2014 PhD students are predicted to graduate on time and the results are compared wih the actual number for validation purpose.

    The Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S) program focuses on increasing the number of underrepresented minorities (URM) receiving advanced degrees in Earth system sciences (ESS). Subscribing to Aristotle's philosophy that the "whole is greater than the sum of its parts", MS PHD'S uses a synergistic model of tiered mentoring practices, successful minority scientist role models, peer-to-peer community building activities, professional development training techniques, networking opportunities, and state of the art virtual communication tools to facilitate the retention and advancement of underrepresented ESS scientists. Using a three-phase program structure supported by a virtual community, URM students in ESS are afforded opportunities to establish mentoring relationships with successful scientists, build meaningful ties with URM peers and future colleagues, strengthen oral and written communication skills, engage in networking opportunities within premier scientific venues, and maintain continuity of networks formed through program participation. Established in 2003, MS PHD'S is now in its ninth cohort. From the original cohort of 24 participants, the program has grown to support 213 participants. Of these 213 participants, 42 have obtained the doctorate and are employed within the ESS workforce. Another 71 are enrolled in doctoral programs. Looking to the future with the purpose of continually furthering its synergistic philosophy, MS PHD'S has developed a new initiative, Beyond the PhD, designed to support and advance the representation of URM scientists within a global workforce.

    The activating transcription factor-4 (ATF-4) is translationally induced under anoxic conditions, mediates part of the unfolded protein response following endoplasmic reticulum (ER) stress, and is a critical regulator of cell fate. Here, we identified the zipper II domain of ATF-4 to interact with the oxygen sensor prolyl-4-hydroxylase domain 3 (PHD3). The PHD inhibitors dimethyloxalylglycine (DMOG) and hypoxia, or proteasomal inhibition, all induced ATF-4 protein levels. Hypoxic induction of ATF-4 was due to increased protein stability, but was independent of the ubiquitin ligase von Hippel-Lindau protein (pVHL). A novel oxygen-dependent degradation (ODD) domain was identified adjacent to the zipper II domain. Mutations of 5 prolyl residues within this ODD domain or siRNA-mediated down-regulation of PHD3, but not of PHD2, was sufficient to stabilize ATF-4 under normoxic conditions. These data demonstrate that PHD-dependent oxygen-sensing recruits both the hypoxia-inducible factor (HIF) and ATF-4 systems, and hence not only confers adaptive responses but also cell fate decisions.

    The ISO/IEEE 11073 (x73) family of standards is a reference frame for medical device interoperability. A draft for an ECG device specialization (ISO/IEEE 11073-10406-d02) has already been presented to the Personal Health Device (PHD) Working Group, and the Standard Communications Protocol for Computer-Assisted ElectroCardioGraphy (SCP-ECG) Standard for short-term diagnostic ECGs (EN1064:2005+A1:2007) has recently been approved as part of the x73 family (ISO 11073-91064:2009). These factors suggest the coordinated use of these two standards in foreseeable telecardiology environments, and hence the need to harmonize them. Such harmonization is the subject of this paper. Thus, a mapping of the mandatory attributes defined in the second draft of the ISO/IEEE 11073-10406-d02 and the minimum SCP-ECG fields is presented, and various other capabilities of the SCP-ECG Standard (such as the messaging part) are also analyzed from an x73-PHD point of view. As a result, this paper addresses and analyzes the implications of some inconsistencies in the coordinated use of these two standards. Finally, a proof-of-concept implementation of the draft x73-PHD ECG device specialization is presented, along with the conversion from x73-PHD to SCP-ECG. This paper, therefore, provides recommendations for future implementations of telecardiology systems that are compliant with both x73-PHD and SCP-ECG.

    Cellular and physiological responses to changes in dioxygen levels in metazoans are mediated via the posttranslational oxidation of hypoxia-inducible transcription factor (HIF). Hydroxylation of conserved prolyl residues in the HIF-{alpha} subunit, catalyzed by HIF prolyl-hydroxylases (PHDs), signals for its proteasomal degradation. The requirement of the PHDs for dioxygen links changes in dioxygen levels with the transcriptional regulation of the gene array that enables the cellular response to chronic hypoxia; the PHDs thus act as an oxygen-sensing component of the HIF system, and their inhibition mimics the hypoxic response. We describe crystal structures of the catalytic domain of human PHD2, an important prolyl-4-hydroxylase in the human hypoxic response in normal cells, in complex with Fe(II) and an inhibitor to 1.7 Angstroms resolution. PHD2 crystallizes as a homotrimer and contains a double-stranded {beta}-helix core fold common to the Fe(II) and 2-oxoglutarate-dependant dioxygenase family, the residues of which are well conserved in the three human PHD enzymes (PHD 1-3). The structure provides insights into the hypoxic response, helps to rationalize a clinically observed mutation leading to familial erythrocytosis, and will aid in the design of PHD selective inhibitors for the treatment of anemia and ischemic disease.

  5. Laboratories, museums, and the comparative perspective: Alan A. Boyden's quest for objectivity in serological taxonomy, 1924-1962.

    The rise of experimentation and the decline of natural history constitute the historiographic backbone to most narratives about the history of the life sciences in the twentieth century. As I argue here, however, natural history practices, such as the collection adn comparison of data from numerous species, adn experimental practices have actually converged throughout the century, giving rise to a new hybrid research culture which is essential to the contemporary life sciences. Looking at some examples of researchers who studied experimentally the relationships between organisms offers a unique window into how the norms, values, and practices of natural history entered the laboratory and, conversely, how the norms, values, and practices of experimentation transformed natural history. this paper concentrates on a largely overlooked episode in the history of the life sciences: the development of Alan A. Boyden's serological taxonomy. In the United States, from the late 1920s to the early 1960s, he was the most prominent advocate of this experimental approach in natural history. His quest for an objective method to understand the relationships among species, his creation of a serological museum where he could apply his comparative perspective, and his continued negotiations between natural historical and experimental traditions, illustrate the rise of a new hybrid research culture in the twentieth century. It also helps us solve a historiographic puzzle, namely how biological diversity become so central in the experimental life sciences, i.e., in a tradition which we generally understand as having focused on a few model organisms, and which relegated the study of biodiversity to naturalists and their museums.

  6. GM-PHD Filter Combined with Track-Estimate Association and Numerical Interpolation

    Full Text Available For the standard Gaussian mixture probability hypothesis density (GM-PHD filter, the number of targets can be overestimated if the clutter rate is too high or underestimated if the detection rate is too low. These problems seriously affect the accuracy of multitarget tracking for the number and the value of measurements and clutters cannot be distinguished and recognized. Therefore, we proposed an improved GM-PHD filter to tackle these problems. Firstly, a track-estimate association was implemented in the filtering process to detect and remove false-alarm targets. Secondly, a numerical interpolation technique was used to compensate the missing targets caused by low detection rate. At the end of this paper, simulation results were presented to demonstrate the proposed GM-PHD algorithm is more effective in estimating the number and state of targets than the previous ones.

  8. Science PhD career preferences: levels, changes, and advisor encouragement.

    Directory of Open Access Journals (Sweden)

    Henry Sauermann

    Full Text Available Even though academic research is often viewed as the preferred career path for PhD trained scientists, most U.S. graduates enter careers in industry, government, or "alternative careers." There has been a growing concern that these career patterns reflect fundamental imbalances between the supply of scientists seeking academic positions and the availability of such positions. However, while government statistics provide insights into realized career transitions, there is little systematic data on scientists' career preferences and thus on the degree to which there is a mismatch between observed career paths and scientists' preferences. Moreover, we lack systematic evidence whether career preferences adjust over the course of the PhD training and to what extent advisors exacerbate imbalances by encouraging their students to pursue academic positions. Based on a national survey of PhD students at tier-one U.S. institutions, we provide insights into the career preferences of junior scientists across the life sciences, physics, and chemistry. We also show that the attractiveness of academic careers decreases significantly over the course of the PhD program, despite the fact that advisors strongly encourage academic careers over non-academic careers. Our data provide an empirical basis for common concerns regarding labor market imbalances. Our results also suggest the need for mechanisms that provide PhD applicants with information that allows them to carefully weigh the costs and benefits of pursuing a PhD, as well as for mechanisms that complement the job market advice advisors give to their current students.

    @@ Dear Editor, Oxygen levels are critical for cellular physiology.Under low oxygen (hypoxia),cells increase glycolysis while limiting mitochondrial oxidative metabolism.Such adaptation is largely mediated by the transcription factors HIF,which accumulate under hypoxia [1,2].Prolyl hydroxylase domain proteins (PHD) function as cellular oxygen sensors and target HIF for subsequent degradation under normoxia [2].The PHD/HIF pathway is conserved in Drosophila,where a single prolyl hydroxylase,Fatiga,has been characterized.We have previously reported that Fatiga regulates cellular growth rates in a HIF-independent manner,yet mechanisms remained elusive [3].

    of EPO transcription. The α subunits of the hypoxia-inducible transcription factor are hydroxylated by three prolyl hydroxylase domain (PHD enzymes, which belong to the iron and 2-oxoglutarate-dependent oxygenase superfamily. Sequence analysis of the genes encoding the PHDs in patients with erythrocytosis has revealed heterozygous germline mutations only occurring in Egl nine homolog 1 (EGLN1, also known as PHD2, the gene that encodes PHD2. To date, 24 different EGLN1 mutations comprising missense, frameshift, and nonsense mutations have been described. The phenotypes associated with the patients carrying these mutations are fairly homogeneous and typically limited to erythrocytosis with normal to elevated EPO. However, exceptions exist; for example, there is one case with development of concurrent paraganglioma (PHD2-H374R. Analysis of the erythrocytosis-associated PHD2 missense mutations has shown heterogeneous results. Structural studies reveal that mutations can affect different domains of PHD2. Some are close to the hypoxia-inducible transcription factor α/2-oxoglutarate or the iron binding sites for PHD2. In silico studies demonstrate that the mutations do not always affect fully conserved residues. In vitro and in cellulo studies showed varying effects of the mutations, ranging from mild effects to severe loss of function. The exact mechanism of a potential tumor-suppressor role for PHD2 still needs to be elucidated. A knockin mouse model expressing the first reported PHD2-P317R mutation recapitulates the phenotype observed in humans (erythrocytosis with inappropriately normal serum EPO levels and demonstrates that haploinsufficiency and partial deregulation of PHD2 is sufficient to cause erythrocytosis.

    Endochondral ossification plays an important role in the formation of the primary ossification centers (POCs) and secondary ossification centers (SOCs) of mammalian long bones. However, the molecular mechanisms that regulate POC and SOC formation are different. We recently demonstrated that Prolyl Hydroxylase Domain-containing Protein 2 (Phd2) is a key mediator of vitamin C effects on bone. We investigated the role of Phd2 on endochondral ossification of the epiphyses by conditionally deleting the Phd2 gene in osteoblasts and chondrocytes. We found that the deletion of Phd2 in osteoblasts did not cause changes in bone parameters in the proximal tibial epiphyses in 5 week old mice. In contrast, deletion of Phd2 in chondrocytes resulted in increased bone mass and bone formation rate (normalized to tissue volume) in long bone epiphyses, indicating that Phd2 expressed in chondrocytes, but not osteoblasts, negatively regulates secondary ossification of epiphyses. Phd2 deletion in chondrocytes elevated mRNA expression of hypoxia-inducible factor (HIF) signaling molecules including Hif-1α, Hif-2α, Vegfa, Vegfb, and Epo, as well as markers for chondrocyte hypertrophy and mineralization such as Col10, osterix, alkaline phosphatase, and bone sialoprotein. These data suggest that Phd2 expressed in chondrocytes inhibits endochondral ossification at the epiphysis by suppressing HIF signaling pathways. PMID:27775044

  5. Hypoxia and loss of PHD2 inactivate stromal fibroblasts to decrease tumour stiffness and metastasis.

    Cancer-associated fibroblasts (CAFs) interact with tumour cells and promote growth and metastasis. Here, we show that CAF activation is reversible: chronic hypoxia deactivates CAFs, resulting in the loss of contractile force, reduced remodelling of the surrounding extracellular matrix and, ultimately, impaired CAF-mediated cancer cell invasion. Hypoxia inhibits prolyl hydroxylase domain protein 2 (PHD2), leading to hypoxia-inducible factor (HIF)-1α stabilisation, reduced expression of αSMA and periostin, and reduced myosin II activity. Loss of PHD2 in CAFs phenocopies the effects of hypoxia, which can be prevented by simultaneous depletion of HIF-1α. Treatment with the PHD inhibitor DMOG in an orthotopic breast cancer model significantly decreases spontaneous metastases to the lungs and liver, associated with decreased tumour stiffness and fibroblast activation. PHD2 depletion in CAFs co-injected with tumour cells similarly prevents CAF-induced metastasis to lungs and liver. Our data argue that reversion of CAFs towards a less active state is possible and could have important clinical implications.

    2013-12-01

    Results from a recent graduate student survey found unsurprisingly that Solar and Space Physics (S&SP) Ph.D. graduate students almost all aspire to have research careers in Solar and Space Physics. This study reports on the research career outcomes over the last decade for S&SP Ph.Ds. We used publication of peer-reviewed articles as the indicator for persistence in a research career. We found that nearly two-thirds (64%) of Ph.D.s who graduated between 2001 to 2009 published refereed-papers four or more years after their Ph.D., while 17% of Ph.D.s never published another paper beyond the year they received their Ph.D. The remaining 19% of Ph.Ds, stopped publishing within three-years of receiving their Ph.D. We found that though there is statistically no difference on persistence of publishing research between graduates of the largest programs compared to all other programs, there are significant differences between programs. We also found there was no gender differences in any of the persistence data (i.e., men and women stop or continue publishing at the same rates). Graduate programs, faculty advisors and potential graduate students can use these data for career planning. This study suggests that a significant majority of S&SP Ph.D.s (77%) find post-doctoral research positions and a majority (56%) find research careers beyond their post-doc.

    The Pygo-BCL9 complex is a chromatin reader, facilitating β-catenin-mediated oncogenesis, and is thus emerging as a potential therapeutic target for cancer. Its function relies on two ligand-binding surfaces of Pygo's PHD finger that anchor the histone H3 tail methylated at lysine 4 (H3K4me) with assistance from the BCL9 HD1 domain. Here, we report the first use of fragment-based screening by NMR to identify small molecules that block protein-protein interactions by a PHD finger. This led to the discovery of a set of benzothiazoles that bind to a cleft emanating from the PHD-HD1 interface, as defined by X-ray crystallography. Furthermore, we discovered a benzimidazole that docks into the H3K4me specificity pocket and displaces the native H3K4me peptide from the PHD finger. Our study demonstrates the ligandability of the Pygo-BCL9 complex and uncovers a privileged scaffold as a template for future development of lead inhibitors of oncogenesis.

    Full Text Available Writers use some textual devices like hedges and boosters in order to contribute to their textual voice. Differences between M.A. theses and Ph.D. dissertations in English Language Teaching (ELT Department in terms of hedges in Turkish context seem to be an overlooked area. Thus, this paper aims to find the similarities and differences between M.A. theses and Ph.D. dissertations about English Language Teaching in terms of hedges. For this purpose, 10 M.A. theses and 10 Ph.D. dissertations were randomly chosen. Data were analyzed and categorized on the basis of contextual features with the help of content analysis. Various hedging tools emerged as a result of content analysis and it was found that hedges used in the Ph.D. dissertations nearly double those in the M.A. theses. Moreover, modals -followed by passivization- are the leading form of hedging while nouns have the least frequency of hedging type, which could explain some of the differences between novice and experienced writers. In the light of these findings, important implications are drawn for graduate and postgraduate students to enhance their writing skills and be familiar with the principles of academic writing for their future career.

  12. Ensuring PhD development of responsible conduct of research behaviors: who's responsible?

    Titus, Sandra L; Ballou, Janice M

    2014-03-01

    The importance of public confidence in scientific findings and trust in scientists cannot be overstated. Thus, it becomes critical for the scientific community to focus on enhancing the strategies used to educate future scientists on ethical research behaviors. What we are lacking is knowledge on how faculty members shape and develop ethical research standards with their students. We are presenting the results of a survey with 3,500 research faculty members. We believe this is the first report on how faculty work with and educate their PhD students on basic research standards. Specifically, we wanted to determine whether individual faculty members, who are advisors or mentors, differ in how they implemented components of responsible conduct of research (RCR) with their PhD students. Mentors were more likely than advisors or supervisors to report working with all of their PhDs, who graduated in the last 5 years, on the 17 recognized critical components of RCR training and research skill development. We also found about half of the faculty members believe RCR is an institutional responsibility versus a faculty responsibility. Less than a quarter have had opportunities to participate in faculty training to be a better mentor, advisor, or research teacher, and about one third of faculty did not or could not remember whether they had guidelines related to their responsibilities to PhD students. We discuss the implications of our findings and focus on ways that PhD research mentoring can be enhanced.

    2016-07-01

    Full Text Available Introduction: Enhancing the quality and dynamicity of higher education programs requires continuous evaluation of curriculums. Reproductive health PhD program was established in 2006 in Iran while recommending that its curriculum be evaluated by assessing graduates’ performance in workplace and surveying students, faculty members and managers. This study aimed to explore challenges of the curriculum of reproductive health PhD program. Methods: Employing a qualitative content analysis approach and using purposive and sometimes opportunistic sampling, experiences and viewpoints of 33 graduates and students of reproductive health PhD program, educational managers and reproductive health board members about the curriculum of reproductive health PhD program were collected through individual interviews and notes in 2014-15. Data were transcribed and important expressions were coded. Classification of similar codes led to preliminary categories. Five main categories were extracted by further classifications. Results: The five main categories included inadequacy of course topics and contents, challenges of student education, failure in realizing curriculum goals, long research period, and ambiguity in graduates’ professional status were appeared; each of these included various subcategories. Conclusion: Results showed that the curriculum of reproductive health PhD program required revisions to meet the program’s mission and designing courses such as sexual health and reinforcing the clinical nature of the program were necessary. Moreover, the results emphasized that the establishment of an independent educational department of reproductive health for managing higher education affairs and greater supervision of the reproductive health board on educational affairs was necessary. Furthermore, reproductive health specialists should be employed in different positions to meet society’s reproductive health needs.

  17. [Research misconduct: Knowledge, actions and attitudes of PhD candidates].

    Hofmann, Bjørn; Holm, Søren

    2016-09-01

    BACKGROUND Increasing attention is being paid to research misconduct in academic journals and in the media, but we know relatively little about its extent or attitudes to research misconduct, or how these are changing. This study therefore aims to investigate PhD candidates' knowledge, own actions and attitudes to specific forms of research misconduct.MATERIAL AND METHOD In autumn 2015, an anonymous questionnaire survey was distributed to all participants in the introductory course for PhD candidates at the Faculty of Medicine at the University of Oslo.RESULTS Altogether 77 PhD candidates (79 %) responded to the questionnaire. A total of 62 % conducted clinical research and 25 % conducted basic research. Around one in four had heard about serious forms of research misconduct in the previous year, and around 4 % were aware of various forms of serious research misconduct in their own department in the previous year. Compared to earlier studies, an increasing number (16 %) responded that they had been subjected to unethical pressure with regard to inclusion or order of authors. Approximately two-thirds were uncertain of whether their department had written policies for academic conduct. One-third of PhD candidates did not disassociate themselves from actions that are generally viewed as scientific misconduct. One-tenth thought it acceptable to falsify or fabricate data in order to expedite publication, one-fifth did not object to taking the credit for others' ideas, and almost half did not believe it was wrong to attempt a number of methods of analysis until one arrived at a significant answer.INTERPRETATION PhD candidates at the Faculty of Medicine were aware of research misconduct, both generally and from their own department. They themselves reported some type of scientific misconduct, and a large majority were uncertain of their department's guidelines. Some of the candidates also accepted several forms of research misconduct.

    2014-01-01

    The growing number of PhD students has spurred debates about the societal relevance of PhD training trajectories. The academic labour market does not provide enough jobs and many PhD graduates will have a career outside academia. It has been questioned whether current PhD training trajectories are still adequate and collaborative research projects are introduced as alternative trajectories. Such trajectories can support the development of a broader set of skills, but might have adverse effect...

  20. PHD1 links cell-cycle progression to oxygen sensing through hydroxylation of the centrosomal protein Cep192.

    PHD1 belongs to the family of prolyl-4-hydroxylases (PHDs) that is responsible for posttranslational modification of prolines on specific target proteins. Because PHD activity is sensitive to oxygen levels and certain byproducts of the tricarboxylic acid cycle, PHDs act as sensors of the cell's metabolic state. Here, we identify PHD1 as a critical molecular link between oxygen sensing and cell-cycle control. We show that PHD1 function is required for centrosome duplication and maturation through modification of the critical centrosome component Cep192. Importantly, PHD1 is also required for primary cilia formation. Cep192 is hydroxylated by PHD1 on proline residue 1717. This hydroxylation is required for binding of the E3 ubiquitin ligase SCF(Skp2), which ubiquitinates Cep192, targeting it for proteasomal degradation. By modulating Cep192 levels, PHD1 thereby affects the processes of centriole duplication and centrosome maturation and contributes to the regulation of cell-cycle progression.

    To describe the funding, education, enrollment, and graduation patterns from economic, social, and administrative sciences PhD programs in colleges and schools of pharmacy in the United States. Economic, social, and administrative sciences PhD programs were identified from the American Association of Colleges of Pharmacy (AACP) Web site. A 41-item online survey instrument was sent to the director of graduate studies of each identified program. Only programs offering a PhD degree were included in the study. Of the 26 programs surveyed, 20 (77%) provided useable responses to the survey instrument. Approximately 91% of PhD programs guarantee funding to incoming students with an average commitment of 2.9 years. On average, students were paid a stipend of $18,000 per year for commitments to research and teaching assistantships, each averaging approximately 2 years in length. Programs admitted an average of 3.5 students per year and graduated approximately 85% of entering students. The majority of students are non-US citizens and accept positions in either academic or industrial positions after graduation. Most economic, social, and administrative sciences PhD programs guarantee funding to incoming PhD candidates. Programs offering funding packages significantly below the average may be at a competitive disadvantage. It is unclear whether the number of students graduating from PhD programs is adequate to fulfill academic and industrial needs.

  2. Substrate preference of the HIF-prolyl hydroxylase-2 (PHD2) and substrate-induced conformational change.

    2013-09-01

    HIF prolyl-4-hydroxylase 2 (PHD2) is a non-heme Fe, 2-oxoglutarate (2OG) dependent dioxygenase that regulates the hypoxia inducible transcription factor (HIF) by hydroxylating two conserved prolyl residues in N-terminal oxygen degradation domain (NODD) and C-terminal oxygen degradation domain (CODD) of HIF-1α. Prior studies have suggested that the substrate preference of PHD2 arises from binding contacts with the β2β3 loop of PHD2. In this study we tested the substrate selectivity of PHD2 by kinetic competition assays, varied ionic strength, and global protein flexibility using amide H/D exchange (HDX). Our results revealed that PHD2 preferred CODD by 20-fold over NODD and that electrostatics influenced this effect. Global HDX monitored by mass spectrometry indicated that binding of Fe(II) and 2OG stabilized the overall protein structure but the saturating concentrations of either NODD or CODD caused an identical change in protein flexibility. These observations imply that both substrates stabilize the β2β3 loop to the same extent. Under unsaturated substrate conditions NODD led to a higher HDX rate than CODD due to its lower binding affinity to PHD2. Our results suggest that loop closure is the dominant contributor to substrate selectivity in PHD2.

    Arda, Berna

    2012-06-01

    Publication ethics, an important subtopic of science ethics, deals with determination of the misconducts of science in performing research or in the dissemination of ideas, data and products. Science, the main features of which are secure, reliable and ethically obtained data, plays a major role in shaping the society. As long as science maintains its quality by being based on reliable and ethically obtained data, it will be possible to maintain its role in shaping the society. This article is devoted to the presentation of opinions of PhD candidate students in health sciences in Ankara concerning publication ethics. The data obtained from 143 PhD students from the fields of medicine, dentistry, pharmacy and veterinary reveal limited but unique experiences. It also shows that plagiarism is one of the worst issues in the publication ethics from the perspective of these young academics.

    2009-01-01

    The PhD viva -- regardless of its format -- has the potential to be a significant rite of passage for the student. It is an experience that can resonate for months or years afterwards. Part of the challenge is that for everyone involved -- student, supervisory team and examiners -- a degree of end-point uncertainty exists. These ambiguities and tensions are perhaps an inherent part of any examination but are particularly characteristic of the examination of the individual and unique body of work that constitutes the doctoral thesis. In recent years, increased attention has been placed on the processes that surround the examination, aiming to increase transparency, consistency and fairness. However, the process of examining a student and their thesis remains challenging and is surrounded by different agendas, ideologies and practices. This paper examines some of the issues surrounding the PhD viva, primarily focusing on the British viva whilst weaving in commentary about the Australian system.

    2001-05-01

    The PHD fingers of the human MLL and Drosophila trx proteins have strong amino acid sequence conservation but their function is unknown. We have determined that these fingers mediate homodimerization and binding of MLL to Cyp33, a nuclear cyclophilin. These two proteins interact in vitro and in vivo in mammalian cells and colocalize at specific nuclear subdomains. Overexpression of the Cyp33 protein in leukemia cells results in altered expression of HOX genes that are targets for regulation by MLL. These alterations are suppressed by cyclosporine and are not observed in cell lines that express a mutant MLL protein without PHD fingers. These results suggest that binding of Cyp33 to MLL modulates its effects on the expression of target genes.

  10. The training, careers, and work of Ph.D. physical scientists: Not simply academic

    Science.gov (United States)

    2002-11-01

    We present an in-depth portrait of the training, careers, and work of recent Ph.D. physical scientists. Use of specialized training varies widely, with about half often using knowledge of their Ph.D. specialty area in their jobs. The use of specialized training does not, however, correlate with job satisfaction. In this and other important measures, there are relatively few differences between "academics" and "nonacademics." Important job skills for all employment sectors include writing, oral presentation, management, data analysis, designing projects, critical thinking, and working in an interdisciplinary context. Rankings given by respondents of graduate training in some of these skill areas were significantly lower than the importance of these skills in the workplace. We also found that the rated quality of graduate training varies relatively little by department or advisor. Finally, although nonacademic aspirations among graduate students are fairly common, these do not appear to be well supported while in graduate school.

  14. Including systematic reviews in PhD programmes and candidatures in nursing - 'Hobson's choice'?

    Science.gov (United States)

    Olsson, Cecilia; Ringnér, Anders; Borglin, Gunilla

    2014-03-01

    Nowadays, gathering and synthesising evidence, i.e. conducting systematic reviews, is considered an important part of any health service research endeavour. Reviewing the literature, however suggest that it is not yet common that PhD students/doctoral candidates publish systematic reviews or even include a high quality review of the literature as a part of their PhD programme or candidature. Implying that systematic reviewing skills might not be acquired by going through an education on a postgraduate level. Additionally, scholars debating systematic reviews 'to be or not to be' as a part of research training seem to be sparse, especially within the field of nursing. In this issue for debate, we would like to propose that the absence of systematic reviews' in this context might severely hamper the 'up and coming' researchers as well as the research conducted. We envisage that this lack can have a negative impact on international nursing practice, and therefore propose that systematic reviews should be considered, whenever appropriate, as a mandatory part of any PhD programme or candidature. We believe that abilities in systematic reviewing will be a sought after research skills in the near future. Including systematic reviews would promote i) refined, well-grounded adequate research questions, ii) PhDs with broad and elevated methodological skills, iii) an increased level of evidence based nursing praxis. However, to make this a reality, supervisors, PhD students, and candidates would need to understand the value of this kind of research activity. Finally, lobbying University faculty boards and grant providers that are not inclined to view literature reviews as 'proper' research or as an important part of health service research, needs to be put on the agenda.

    Histone covalent modifications regulate many, if not all, DNA-templated processes, including gene expression and DNA damage response. The biological consequences of histone modifications are mediated partially by evolutionarily conserved 'reader/effector' modules that bind to histone marks in a modification- and context-specific fashion and subsequently enact chromatin changes or recruit other proteins to do so. Recently, the Plant Homeodomain (PHD) finger has emerged as a class of specialized 'reader' modules that, in some instances, recognize the methylation status of histone lysine residues, such as histone H3 lysine 4 (H3K4). While mutations in catalytic enzymes that mediate the addition or removal of histone modifications (i.e., 'writers' and 'erasers') are already known to be involved in various human diseases, mutations in the modification-specific 'reader' proteins are only beginning to be recognized as contributing to human diseases. For instance, point mutations, deletions or chromosomal translocations that target PHD fingers encoded by many genes (such as recombination activating gene 2 (RAG2), Inhibitor of Growth (ING), nuclear receptor-binding SET domain-containing 1 (NSD1) and Alpha Thalassaemia and Mental Retardation Syndrome, X-linked (ATRX)) have been associated with a wide range of human pathologies including immunological disorders, cancers, and neurological diseases. In this review, we will discuss the structural features of PHD fingers as well as the diseases for which direct mutation or dysregulation of the PHD finger has been reported. We propose that misinterpretation of the epigenetic marks may serve as a general mechanism for human diseases of this category. Determining the regulatory roles of histone covalent modifications in the context of human disease will allow for a more thorough understanding of normal and pathological development, and may provide innovative therapeutic strategies

    Today, postgraduate students experience a variety of stresses and anxiety in different situations of academic cycle. Stress and anxiety have been defined as a syndrome shown by emotional exhaustion and reduced personal goal achievement. This article addresses the causes and different strategies of coping with this phenomena by PhD students at Iranian Universities of Medical Sciences. The study was conducted by a qualitative method using conventional content analysis approach. Through purposive sampling, 16 postgraduate medical sciences PhD students were selected on the basis of theoretical sampling. Data were gathered through semistructured interviews and field observations. Six hundred fifty-four initial codes were summarized and classified into 4 main categories and 11 subcategories on the thematic coding stage dependent on conceptual similarities and differences. The obtained codes were categorized under 4 themes including "thesis as a major source of stress," "supervisor relationship," "socioeconomic problem," and "coping with stress and anxiety." It was concluded that PhD students experience stress and anxiety from a variety of sources and apply different methods of coping in effective and ineffective ways. Purposeful supervision and guidance can reduce the cause of stress and anxiety; in addition, coping strategy must be in a thoughtful approach, as recommended in this study.

    Full Text Available This paper describes how computer science doctoral writers construct the closing chapters of their PhD theses. The data are drawn from the chapters playing a concluding role of 48 PhD theses defended at the University of Glasgow from 2008 to 2014. The analysis applied a qualitative-quantitative approach. The titles of the concluding chapters of the theses were first examined and also their divisions into sections and sub-sections. Then the chapters were subjected to a move-step analysis: Move 1 (M1 “Revisiting the study”; Move 2 (M2 “Consolidating research space”; Move 3 (M3 “Proposing practical applications and implications”, Move 4 (M4 “Recommending future work” and Move 5 (M5 “Recapitulating the study”. The results revealed that most of the computer science PhD theses have one final concluding chapter with three main moves: M1, M2 and M4. The most frequent steps are “reviewing the work carried out” and “summarizing the specific work reported in every thesis chapter” in M1, “presenting results and contributions”, “answering the initial research questions or hypotheses”, and “making claims” in M2, and “acknowledging limitations” and “suggesting further research” in M4. Movestep patterns appear in recurrent cycles throughout the concluding chapters. Several suggestions for pedagogical purposes are provided.

    2008-01-01

    More than 14 percent of the PhD's awarded in the United States during the first four decades of the twentieth century went to women, a proportion not achieved again until the 1980s. This book is the result of a study in which the authors identified all of the American women who earned PhD's in mathematics before 1940, and collected extensive biographical and bibliographical information about each of them. By reconstructing as complete a picture as possible of this group of women, Green and LaDuke reveal insights into the larger scientific and cultural communities in which they lived and worked. The book contains an extended introductory essay, as well as biographical entries for each of the 228 women in the study. The authors examine family backgrounds, education, careers, and other professional activities. They show that there were many more women earning PhD's in mathematics before 1940 than is commonly thought. Extended biographies and bibliographical information are available from the companion website fo...

    2016-06-01

    Results from a recent graduate student survey found unsurprisingly that Solar and Space Physics (S&SP) PhD graduate students almost all aspire to have research careers in Solar and Space Physics. This study reports on the research career persistence over the first decade of the new millennium for S&SP PhDs. We used publication of science citation indexed articles as the indicator for persistence in a research career. We found that nearly two thirds (64%) of PhDs who graduated between 2001 and 2009 published refereed papers in 2012 or 2013, while 17% of PhDs never published another paper beyond the year they received their PhD. The remaining 19% of PhDs stopped publishing within three years of receiving their PhD. We found no gender difference between research persistence. We also found that though there is statistically no difference on persistence of publishing research between graduates of the largest programs compared to all other programs, there are significant differences between individual programs. This study indicates that a majority of S&SP PhDs find research careers but that a significant fraction pursue careers where publishing in science citation indexed journals is not required. Graduate programs, advisors, and potential graduate students can use these data for career planning and developing mentoring programs that meet the career outcomes of all of their graduates.

  1. Advancing Minorities and Women to the PhD in Physics and Astronomy

    2017-01-01

    We briefly review the current status of underrepresented minorities in physics and astronomy: The underrepresentation of Black-, Hispanic-, and Native-Americans is an order of magnitude problem. We then describe the Fisk-Vanderbilt Masters-to-PhD Bridge program as a successful model for addressing this problem. Since 2004 the program has admitted 110 students, 90% of them underrepresented minorities (50% female), with a retention rate of 90%. The program has become the top producer of African American master's degrees in physics, and is now one of the top producers of minority PhDs in astronomy, materials science, and physics. We summarize the main features of the program including its core strategies: (1) replacing the GRE in admissions with indicators that are better predictive of long-term success, (2) partnering with a minority-serving institution for student training through collaborative research, and (3) using the master's degree as a deliberate stepping stone to the PhD. We show how misuse of the GRE in graduate admissions may by itself in large part explain the ongoing underrepresentation of minorities in PhD programs, and we describe our alternate methods to identify talented individuals most likely to succeed. We describe our mentoring model and toolkit which may be utilized to enhance the success of all PhD students.

  2. Substrate-Trapped Interactors of PHD3 and FIH Cluster in Distinct Signaling Pathways

    2016-03-01

    Full Text Available Amino acid hydroxylation is a post-translational modification that regulates intra- and inter-molecular protein-protein interactions. The modifications are regulated by a family of 2-oxoglutarate- (2OG dependent enzymes and, although the biochemistry is well understood, until now only a few substrates have been described for these enzymes. Using quantitative interaction proteomics, we screened for substrates of the proline hydroxylase PHD3 and the asparagine hydroxylase FIH, which regulate the HIF-mediated hypoxic response. We were able to identify hundreds of potential substrates. Enrichment analysis revealed that the potential substrates of both hydroxylases cluster in the same pathways but frequently modify different nodes of signaling networks. We confirm that two proteins identified in our screen, MAPK6 (Erk3 and RIPK4, are indeed hydroxylated in a FIH- or PHD3-dependent mechanism. We further determined that FIH-dependent hydroxylation regulates RIPK4-dependent Wnt signaling, and that PHD3-dependent hydroxylation of MAPK6 protects the protein from proteasomal degradation.

    As senior population increases, various healthcare devices and services are developed such as fall detection device, home hypertension management service, and etc. However, to vitalize healthcare devices and services market, standardization for interoperability between device and service must precede. To achieve the standardization goal, the IEEE 11073 Personal Health Device (PHD) group has been standardized many healthcare devices, but until now there are few devices compatible with the PHD standard. One of main reasons is that it isn't easy for device manufactures to implement standard communication module by analyzing standard documents of over 600 pages. In this paper, we propose a standard message generation toolkit to easily standardize existing non-standard healthcare devices. The proposed toolkit generates standard PHD messages using inputted device information, and the generated messages are adapted to the device with the standard state machine file. For the experiments, we develop a reference H/W, and test the proposed toolkit with three healthcare devices: blood pressure, weighting scale, and glucose meter. The proposed toolkit has an advantage that even if the user doesn't know the standard in detail, the user can easily standardize the non-standard healthcare devices.

    Full Text Available Increasing biomedical workforce diversity remains a persistent challenge. Recent reports have shown that biomedical sciences (BMS graduate students become less interested in faculty careers as training progresses; however, it is unclear whether or how the career preferences of women and underrepresented minority (URM scientists change in manners distinct from their better-represented peers. We report results from a survey of 1500 recent American BMS Ph.D. graduates (including 276 URMs that examined career preferences over the course of their graduate training experiences. On average, scientists from all social backgrounds showed significantly decreased interest in faculty careers at research universities, and significantly increased interest in non-research careers at Ph.D. completion relative to entry. However, group differences emerged in overall levels of interest (at Ph.D. entry and completion, and the magnitude of change in interest in these careers. Multiple logistic regression showed that when controlling for career pathway interest at Ph.D. entry, first-author publication rate, faculty support, research self-efficacy, and graduate training experiences, differences in career pathway interest between social identity groups persisted. All groups were less likely than men from well-represented (WR racial/ethnic backgrounds to report high interest in faculty careers at research-intensive universities (URM men: OR 0.60, 95% CI: 0.36-0.98, p = 0.04; WR women: OR: 0.64, 95% CI: 0.47-0.89, p = 0.008; URM women: OR: 0.46, 95% CI: 0.30-0.71, p<0.001, and URM women were more likely than all other groups to report high interest in non-research careers (OR: 1.93, 95% CI: 1.28-2.90, p = 0.002. The persistence of disparities in the career interests of Ph.D. recipients suggests that a supply-side (or "pipeline" framing of biomedical workforce diversity challenges may limit the effectiveness of efforts to attract and retain the best and most

  8. Factors that facilitate or inhibit interest of domestic students in the engineering PhD: A mixed methods study

    Science.gov (United States)

    Howell Smith, Michelle C.

    Given the increasing complexity of technology in our society, the United States has a growing demand for a more highly educated technical workforce. Unfortunately, the proportion of United States citizens earning a PhD in engineering has been declining and there is concern about meeting the economic, national security and quality of life needs of our country. This mixed methods sequential exploratory instrument design study identified factors that facilitate or inhibit interest in engineering PhD programs among domestic engineering undergraduate students in the United States. This study developed a testable theory for how domestic students become interested in engineering PhD programs and a measure of that process, the Exploring Engineering Interest Inventory (EEII). The study was conducted in four phases. The first phase of the study was a qualitative grounded theory exploration of interest in the engineering PhD. Qualitative data were collected from domestic engineering students, engineering faculty and industry professional who had earned a PhD in engineering. The second phase, instrument development, developed the Exploring Engineering Interest Inventory (EEII), a measurement instrument designed with good psychometric properties to test a series of preliminary hypotheses related to the theory generated in the qualitative phase. In the third phase of the study, the EEII was used to collect data from a larger sample of junior and senior engineering majors. The fourth phase integrated the findings from the qualitative and quantitative phases. Four factors were identified as being significant influences of interest in the engineering PhD: Personal characteristics, educational environment, misperceptions of the economic and personal costs, and misperceptions of engineering work. Recommendations include increasing faculty encouragement of students to pursue an engineering PhD and programming to correct the misperceptions of the costs of the engineering PhD and the

    Columbia University's Bridge to the Ph.D. in the Natural Sciences Program is increasing the number of underrepresented scholars entering graduate programs and equipping them to succeed in these programs. In a given year, three to five Bridge participants are hired as full-time Columbia University research assistants for up to two years. Now in its seventh year, the Program supports seven participants, and its alumni (including five astronomers) have gone on to Ph.D. programs across the country. Although to date fewer than 40 people have participated in the Program, a number too small for an exclusively statistical evaluation of its effectiveness, we are collecting invaluable longitudinal data on the career progressions of underrepresented aspiring scientists across the natural sciences. At least a dozen Bridge alumni will earn their Ph.D. in the next two-three years, and we will then learn much more about the impact that the Bridge Program has had on our participants' trajectories. Among other things, we hope to use these data to determine the Program's effectiveness in developing feelings of self-efficacy and participants' confidence in their ability to succeed in doctoral programs, to measure the rate at which Bridge alumni successfully complete doctoral programs relative to their peers, and to identify the aspects of the Program that participants find most helpful to their progress at different stages of their paths to and through doctoral programs. Here we describe the data we have already obtained as part of our on-going study, and preliminary results from our analysis.

    Therapeutic angiogenesis has been considered as a potential strategy for treating peripheral artery diseases including hind-limb ischemia (HLI); however, no effective drug-based treatment is currently available. Here we showed that intramuscular administration of salidroside, an active compound of Chinese herb Rhodiola, could robustly enhance blood perfusion recovery by promoting neovascularization in HLI mice. We revealed that salidroside promoted skeletal muscle cell migration and paracrine function through inhibiting the transcriptional level of prolyl-hydroxylase domain 3 (PHD3) without affecting PHD1 and PHD2. Paracrine signals from salidroside-treated skeletal muscle cells enhanced endothelial and smooth muscle cells migration, while inhibition of FGF2/FGF2R and PDGF-BB/PDGFR-β pathways abolished this effect, as well as neovascularization in HLI mice. Furthermore, we elucidated that salidroside inhibition on PHD3 might occur through estrogen receptor alpha (ERα). Together, our findings highlights the potential application of salidroside as a novel pharmalogical inhibitor of ERα/PHD3 axis for therapeutic angiogenesis in HLI diseases. PMID:28266625

    For decades, top scientists in colleges and universities pursued a clear path to success: enroll in a prestigious graduate program, conduct research, publish papers, complete the PhD, pursue postdoctoral work. With perseverance and a bit of luck, a tenure-track professorship awaited at the end. In today s academic job market, this scenario represents the exception. As the number of newly conferred science PhDs keeps rising, the number of tenured professorships remains stubbornly stagnant. Only 14 percent of those with PhDs in science occupy tenure-track positions five years after completing their degree.

    As the number of seniors with chronic disease increases, the need of home healthcare settop-box is increased to manage their chronic disease in their home environment. Using the home healthcare settop-box, the patients can regularly check their health data, and finally, it can lead the decrease of medical expenses. For the home healthcare settop-box, the most important factor is the standard compatibility, which can interoperate with standard devices of any other companies. In this paper, we propose a home healthcare settop-box using ISO/IEEE 11073 PHD standard. It collects health data according to the PHD standard, and provides a chronic-care service based on the collected data. The proposed settop-box is connected with 3 devices of weigh scale, blood pressure monitor, and glucose meter, and tested at 10 homes for a month. Lastly, the proposed settop-box can be used for various healthcare services such as Google Health and Telemedicine Services using a healthcare platform server.

    Columbia University's Bridge to the Ph.D. in the Natural Sciences Program aims to enhance the participation of students from underrepresented groups in Ph.D. programs. To achieve this, the Bridge Program provides an intensive research, coursework, and mentoring experience to post-baccalaureates seeking to strengthen their graduate school applications and to prepare for the transition into graduate school. To date, 20 Bridge Program alumni --- including four in astronomy --- have gone on to Ph.D. programs at Columbia, the University of Michigan, Johns Hopkins, the University of Washington, Albert Einstein, Yale, and SUNY-Albany, among others. In this talk, I will touch on some of the connections between Pre-MAP and the Bridge Program, and particularly how my involvement in the former prepared me to lead the latter.

  3. Short Hairpin RNA Silencing of PHD-2 Improves Neovascularization and Functional Outcomes in Diabetic Wounds and Ischemic Limbs.

    Directory of Open Access Journals (Sweden)

    Kevin J Paik

    Full Text Available The transcription factor hypoxia-inducible factor 1-alpha (HIF-1α is responsible for the downstream expression of over 60 genes that regulate cell survival and metabolism in hypoxic conditions as well as those that enhance angiogenesis to alleviate hypoxia. However, under normoxic conditions, HIF-1α is hydroxylated by prolyl hydroxylase 2, and subsequently degraded, with a biological half-life of less than five minutes. Here we investigated the therapeutic potential of inhibiting HIF-1α degradation through short hairpin RNA silencing of PHD-2 in the setting of diabetic wounds and limb ischemia. Treatment of diabetic mouse fibroblasts with shPHD-2 in vitro resulted in decreased levels of PHD-2 transcript demonstrated by qRT-PCR, higher levels of HIF-1α as measured by western blot, and higher expression of the downstream angiogenic genes SDF-1 and VEGFα, as measured by qRT-PCR. In vivo, shPHD-2 accelerated healing of full thickness excisional wounds in diabetic mice compared to shScr control, (14.33 ± 0.45 days vs. 19 ± 0.33 days and was associated with an increased vascular density. Delivery of shPHD-2 also resulted in improved perfusion of ischemic hind limbs compared to shScr, prevention of distal digit tip necrosis, and increased survival of muscle tissue. Knockdown of PHD-2 through shRNA treatment has the potential to stimulate angiogenesis through overexpression of HIF-1α and upregulation of pro-angiogenic genes downstream of HIF-1α, and may represent a viable, non-viral approach to gene therapy for ischemia related applications.

  4. The PHD finger of human UHRF1 reveals a new subgroup of unmethylated histone H3 tail readers.

    Nada Lallous

    Full Text Available The human UHRF1 protein (ubiquitin-like containing PHD and RING finger domains 1 has emerged as a potential cancer target due to its implication in cell cycle regulation, maintenance of DNA methylation after replication and heterochromatin formation. UHRF1 functions as an adaptor protein that binds to histones and recruits histone modifying enzymes, like HDAC1 or G9a, which exert their action on chromatin. In this work, we show the binding specificity of the PHD finger of human UHRF1 (huUHRF1-PHD towards unmodified histone H3 N-terminal tail using native gel electrophoresis and isothermal titration calorimetry. We report the molecular basis of this interaction by determining the crystal structure of huUHRF1-PHD in complex with the histone H3 N-terminal tail. The structure reveals a new mode of histone recognition involving an extra conserved zinc finger preceding the conventional PHD finger region. This additional zinc finger forms part of a large surface cavity that accommodates the side chain of the histone H3 lysine K4 (H3K4 regardless of its methylation state. Mutation of Q330, which specifically interacts with H3K4, to alanine has no effect on the binding, suggesting a loose interaction between huUHRF1-PHD and H3K4. On the other hand, the recognition appears to rely on histone H3R2, which fits snugly into a groove on the protein and makes tight interactions with the conserved aspartates D334 and D337. Indeed, a mutation of the former aspartate disrupts the formation of the complex, while mutating the latter decreases the binding affinity nine-fold.

  5. The Road to Become a Legitimate Scholar: A Case Study of International PhD Students in Science and Engineering

    Full Text Available The purpose of the doctoral education process is to create and legitimize scholarly researchers. This transformation, from student to scholar, is widely discussed in the literature. However, recent rapid changes in university culture have resulted in less time for supervision, stricter completion deadlines, and a greater focus on efficiency and productivity. This has had an impact on this transition process, and this impact has not been widely studied. The aim of this article is to understand the consequences of the current trends for PhD students and the education of PhD students in general. The article is based on interviews with 14 international students from two different research programs at the Faculty of Engineering and Science at Aalborg University in Denmark. The case of international PhD students in a western setting is singled out as a challenging case for becoming a legitimate scholar, since they face the additional challenge of becoming socialised into their new foreign setting. Overall, the study concludes that the transition process of doctoral students is affected by the way different supervisors deal with current university trends and how PhD students fit or do not fit into their knowledge production practices. The study identifies matches or mismatches in a knowledge production perspective, quality of contact, and degree of independence of the PhD student as factors that influence whether a transition process can be marked as sound, troublesome, or lacking. Finally, the study identifies an overall risk of neglecting the more interdependent types of international PhD students. Suggestions are given as how to address this risk.

  6. Hypoxia and loss of PHD2 inactivate stromal fibroblasts to decrease tumour stiffness and metastasis

    2015-01-01

    Cancer-associated fibroblasts (CAFs) interact with tumour cells and promote growth and metastasis. Here, we show that CAF activation is reversible: chronic hypoxia deactivates CAFs, resulting in the loss of contractile force, reduced remodelling of the surrounding extracellular matrix and......, which can be prevented by simultaneous depletion of HIF-1α. Treatment with the PHD inhibitor DMOG in an orthotopic breast cancer model significantly decreases spontaneous metastases to the lungs and liver, associated with decreased tumour stiffness and fibroblast activation. PHD2 depletion in CAFs co...

    2004-12-01

    How did the 2003 Minorities Striving and Pursuing Higher Degrees of Success (MS PHD'S) in Ocean Sciences Program customize evaluative methodology and instruments to align with program goals and processes? How is data captured to document cognitive and affective impact? How are words and numbers utilized to accurately illustrate programmatic outcomes? How is compliance with implicit and explicit funding regulations demonstrated? The 2003 MS PHD'S in Ocean Sciences Program case study provides insightful responses to each of these questions. MS PHD'S was developed by and for underrepresented minorities to facilitate increased and sustained participation in Earth system science. Key components of this initiative include development of a community of scholars sustained by face-to-face and virtual mentoring partnerships; establishment of networking activities between and among undergraduate, graduate, postgraduate students, scientists, faculty, professional organization representatives, and federal program officers; and provision of forums to address real world issues as identified by each constituent group. The evaluative case study of the 2003 MS PHD'S in Ocean Sciences Program consists of an analysis of four data sets. Each data set was aligned to document progress in the achievement of the following program goals: Goal 1: The MS PHD'S Ocean Sciences Program will successfully market, recruit, select, and engage underrepresented student and non-student participants with interest/ involvement in Ocean Sciences; Goal 2: The MS PHD'S Ocean Sciences Program will provide meaningful engagement for participants as determined by quantitative analysis of user-feedback; Goal 3: The MS PHD'S Ocean Sciences Program will provide meaningful engagement for participants as determined by qualitative analysis of user-feedback, and; Goal 4: The MS PHD'S Ocean Sciences Program will develop a constituent base adequate to demonstrate evidence of interest, value, need and sustainability in

    The presence of a solvent is often viewed as indispensable to explain the structure of peptides and proteins. However, well defined secondary structure motifs (helices, sheets, ...) also exist in vacuo, offering a unique ``clean room'' condition to quantify the stabilizing interactions. We here unravel the structure of LysineH^+ capped polyalanine peptides Ac-Alan-LysH^+ (n-5,10,15), by combining experimental multi-photon IR spectra obtained using the FELIX free-electron laser at room-temperature with van der Waals-corrected all-electron density-functional theory (DFT) in the generalized gradient approximation in the FHI-aims code [1]. Earlier ion mobility studies of these molecules indicate helical structure [2], which we here demonstrate quantitatively. For n=5, we find a close energetic competition of different helix motifs (α, 310), with similar and good agreement between measured and calculated vibrational spectra. We show how the LysH^+ termination acts to induce helices also for longer peptides, and how vibrational modes develop with helix length (n=10,15), yielding, e.g., a softening of collective modes towards the infinite helix limit.

We have at the Department of Radiation Biology developed a transcriptionally targeting suicide gene therapy system which is built on a double stranded DNA plasmid...... framework. One of the most significant barriers for efficient plasmid transport however, is the nuclear envelope that compartmentalizes the transcriptional machinery from the translational in a human cell.

    An equity research analyst's job is to determine whether the price of a stock is likely to go up or down. For science-based businesses, particularly biotechnology companies, a PhD in the life sciences can be very helpful in making this determination. I transitioned from a postdoc position to working in equity research. Here I present information on how I made the transition, an overview of the day-to-day activities of an analyst, and thoughts on how to prepare to look for a job in finance. There are significant positives to working on Wall Street, including exposure to cutting-edge clinical/translational research, access to some of the best scientists in the world, a dynamic work environment, and compensation that generally exceeds academic salaries. This comes at the cost of some independence and the satisfaction of being able to call oneself a scientist.

  17. Developing PhD Nurse Scientists: Do Bachelor of Science in Nursing Honors Programs Help?

    Neuberger, Geri B

    2016-10-01

    The critical need for more nurses with research doctoral degrees to replace vacancies among retiring nursing faculty and nurse administrators is identified. The Future of Nursing report recommends that the number of nurses with PhD degrees double by 2020. Encouraging nursing students to begin doctoral education early in their careers is essential to meeting this goal now and in the future. One method to promote early enrollment into doctoral education is participation in a bachelor of science in nursing (BSN) honors program. We describe the recruitment and application process, mentor selection, scholarly activities, and publication of final manuscripts for one such program. The success of one BSN honors program in enabling graduation with university honors and encouraging enrollment and graduation with doctoral degrees is described. The development of more BSN Honors programs and enhancement of activities of current programs are recommended. [J Nurs Educ. 2016;55(10):579-582.]. Copyright 2016, SLACK Incorporated.

    By the middle of 1993, > 30,000 protein sequences has been listed. For 1000 of these, the three-dimensional (tertiary) structure has been experimentally solved. Another 7000 can be modelled by homology. For the remaining 21,000 sequences, secondary structure prediction provides a rough estimate of structural features. Predictions in three states range between 35% (random) and 88% (homology modelling) overall accuracy. Using information about evolutionary conservation as contained in multiple sequence alignments, the secondary structure of 4700 protein sequences was predicted by the automatic e-mail server PHD. For proteins with at least one known homologue, the method has an expected overall three-state accuracy of 71.4% for proteins with at least one known homologue (evaluated on 126 unique protein chains).

    2015-01-01

    This article describes fundraising strategies by a School of Nursing to support a post-master's accelerated (3-year) PhD degree program. A sample proposal to solicit funds is included, as well as a contract that students sign before accepting the scholarship and agreeing to teach for 3 years or repay the money. The first campaign raised $2.3 million for ten students, and the second campaign raised $1.3 million for six students. One useful marketing strategy is to show the impact of an investment in educating ten doctoral students who will become faculty and teach 100 additional students per year, who will then become professionals caring for thousands of patients during their careers. Over a 10 year period, the impact of an accelerated program is enormous, with 660 students taught who in their lifetime will care for 2.4 million patients. The article also discusses motivation and mind sets for giving to promote success in fundraising.

    2017-05-01

    Full Text Available In recent decades some countries of the Middle East have offered facilities to attract international students to pursue their higher education within their higher education institutions. The purpose of this study is to understand the difficulties faced by these students while conducting their studies abroad, and in doing so, to broaden the awareness of the challenges they face to complete their research. The participants of this qualitative study are international PhD students studying at a Middle Eastern public university. The university has reported increasing enrollment of international students, particularly from Africa in the last few years. Data were collected using a set of semi-structured interviews that drew out information on critical incidents that characterized the kind of difficulties students had faced in their studies. The data collected was further analyzed using a qualitative software package, NVivo (QSR International, 11. Six main themes came out from the content analysis of the interviews, which are the role of the adviser, student features, funding issues, family engagement, research and psychological obstacles which provide a holistic picture of student perspectives on the factors that influence degree progress. While these students might have faced difficulties mentioned in existing literature, this study argues that the participants have indicated experiencing psychological obstacles that were not described in earlier studies, such as the state of mind they were in as a result of being worried for family members due to war or violence in their home countries, and drop in currency exchange rates and difficulties in acquiring money due to international sanctions imposed against their countries. This study provides important thoughts on the factors that impact the degree progress of international PhD students from Africa, while at the same time revealing a serious gap in the advisers’ role which can contribute to the

    William Collins, Ph.D., received his B.S. and M.Sc. degrees in entomology from Michigan State University. He completed his Ph.D. at Rutgers University in two years, just before being inducted into the Army to serve in the Korean War. He was assigned to Fort Detrick at the Biological Warfare Research Laboratories and after three years returned to Rutgers as an extension entomologist. He accepted a position in 1959 with the U.S. Public Health Service, with which he has worked for the last 50 years. In 1963, the Public Health Service laboratory moved to Atlanta and Dr. Collins' group began working with non-human primates following the discovery that monkey malarias were transmissible to humans. Parasites from monkeys or apes isolated in Asia, South America, and Africa were sent to the laboratory in Chamblee, Georgia, where they were adapted and transmitted to laboratory-maintained primates and their life cycles described and characterized. Transmissions to human volunteers were also attempted. In 1973, the laboratory operation was transferred to the CDC, and the emphasis changed from the study of monkey malaria in monkeys to that of human malaria in monkeys. During the last 25 to 30 years, different isolates of human malaria parasites have been adapted to New World monkeys to characterize the isolates for the development and testing of drugs and vaccines. Dr. Collins' task has been to identify and choose the best combination of vector-parasite-host combinations for testing each vaccine candidate. He has co-authored more than 450 manuscripts and has been awarded the U.S. Public Health Service Superior Service Award, The Joseph A. LaPrince Medal for Malariology from the American Society of Tropical Medicine and Hygiene, The Distinguished Service Award of the Department of Health and Human Services, the William Watson Medal of Excellence from the Centers for Disease Control and Prevention, and the Hoogstraal Medal from the American Committee of Medical Entomology.

    We have examined the success rates of 19 American, Canadian, Australian, and Dutch graduate programs in producing astronomers. A 20-year baseline was considered (1975-1994), incorporating 897 PhD recipients. The major conclusion from our study is that the fraction of PhD graduates still involved in astronomical research is surprisingly insensitive to the institutional source of one's PhD. With few exception, 55-75% of graduates, regardless of PhD source, remain active in the astronomical research community. While it remains true that graduates of so-called ``prestigious'' programs preferentially populate the same, it is also clear that an abundance of opportunities exist at smaller ``non-prestigious'' institutions, liberal arts colleges, government, and industry. The latter, of course, generally carry enhanced administrative and/or teaching duties, but, on the other hand, do not entirely preclude a role in the research community. A Kepler-Meier survival analysis of two disparate institutes demonstrates that `...

    Histone methylation occurs on both lysine and arginine residues, and its dynamic regulation plays a critical role in chromatin biology. Here we identify the UHRF1 PHD finger (PHD{sub UHRF1}), an important regulator of DNA CpG methylation, as a histone H3 unmodified arginine 2 (H3R2) recognition modality. This conclusion is based on binding studies and cocrystal structures of PHD{sub UHRF1} bound to histone H3 peptides, where the guanidinium group of unmodified R2 forms an extensive intermolecular hydrogen bond network, with methylation of H3R2, but not H3K4 or H3K9, disrupting complex formation. We have identified direct target genes of UHRF1 from microarray and ChIP studies. Importantly, we show that UHRF1's ability to repress its direct target gene expression is dependent on PHD{sub UHRF1} binding to unmodified H3R2, thereby demonstrating the functional importance of this recognition event and supporting the potential for crosstalk between histone arginine methylation and UHRF1 function.

    2012-01-01

    In this study, we focused on the interoperability and authentication of medical devices in the context of telemedical systems. A recent standard called the ISO/IEEE 11073 Personal Health Device (X73-PHD) Standards addresses the device interoperability problem by defining common protocols for agent (medical device) and manager (appliance) interface. The X73-PHD standard however has not addressed security and authentication of medical devices which is important in establishing integrity of a telemedical system. We have designed and implemented a security policy within the X73-PHD standards. The policy will enable device authentication using Asymmetric-Key Cryptography and the RSA algorithm as the digital signature scheme. We used two approaches for performing the digital signatures: direct software implementation and use of embedded security modules (ESM). The two approaches were evaluated and compared in terms of execution time and memory requirement. For the standard 2048-bit RSA, ESM calculates digital signatures only 12% of the total time for the direct implementation. Moreover, analysis shows that ESM offers more security advantage such as secure storage of keys compared to using direct implementation. Interoperability with other systems was verified by testing the system with LNI Healthlink, a manager software that implements the X73-PHD standard. Lastly, security analysis was done and the system's response to common attacks on authentication systems was analyzed and several measures were implemented to protect the system against them.

    Ambient assisted living and integrated care in an aging society is based on the vision of the lifelong Electronic Health Record calling for HealthCare Information Systems and medical device interoperability. For medical devices this aim can be achieved by the consistent implementation of harmonized international interoperability standards. The ISO/IEEE 11073 (x73) family of standards is a reference standard for medical device interoperability. In its Personal Health Device (PHD) version several devices have been included, but an ECG device specialization is not yet available. On the other hand, the SCP-ECG standard for short-term diagnostic ECGs (EN1064) has been recently approved as an international standard ISO/IEEE 11073-91064:2009. In this paper, the relationships between a proposed x73-PHD model for an ECG device and the fields of the SCP-ECG standard are investigated. A proof-of-concept implementation of the proposed x73-PHD ECG model is also presented, identifying open issues to be addressed by standards development for the wider interoperability adoption of x73-PHD standards.

    Historically, there has been a lack of ethnic and gender diversity in the geo-sciences. The Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S) Professional Development Program provides a bridge to young scientists of diverse backgrounds who in turn will impact many. In a process of 3 phases, the program introduces the students to the scientific community through participation in professional and society meetings and networking with scientists and personnel within federal agencies, academic institutions and STEM-based industries. The program builds confidence, offers role models for professional development and provides students support during their education. Upon completion, students achieve a high level of self-actualization and self-esteem combined with individual growth. They become part of a community that continuously provides support and security to each other. This support is tangible through the mentor/mentee relationships which will help with individual growth throughout the mentoring cycle. Having role models and familiar faces to whom mentees can relate to will encourage our students to succeed in the STEM's field. To date, 159 students have participated in the program: 26 have successfully completed their PhD and 56 are currently enrolled in the PhD programs nationwide. The MS PHD'S Program creates a forum of diverse peoples by diverse peoples with diverse interest and strength, where the ongoing goal is to continually raise the bar for each individual. MS PHD'S establishes a nurturing goal-oriented environment for the geo scientist of the future who in turn will make profound contributions on a local, national and global scale. To conclude, MSPHD'S not only bridges the gap of unrepresented minorities in STEM careers, but also generates educational approaches to make the earth system sciences available to more, impacting all.

  6. Ecospirituality in the Age of Technological Overkill: Body-Time Reclamation in the Fiction of Alan Lightman and Don DeLillo

    2011-01-01

    Full Text Available In exploring the link between ecospirituality and the hard sciences, I argue that theformer provides a much-needed complement to the latter. The fragmentation ofdisciplinary pursuits fostered by the Enlightenment and by the continued progress ofunquestioned technological advance as an end in itself finds its ultimate expression inour current disconnection from the natural world, from each other, and even fromourselves. As a corrective to such disconnection, ecospiritual impulses emerge in anattempt to unify a discombobulated subject, a self so fragmented by the multiplenarratival requirements of a communication-obsessed age (where we can be reached bycell phone, regular phone, multiple email addresses, Facebook, and other social mediathat the "contemplative" facet of being human within the rhythms of the natural worldis all but obscured-indeed, is hardly given the requisite environment in which tofunction. Against this over-reliance on technology, on where the hard sciences have ledus, ecospirituality emerges as a balm for the terrorized human spirit. Don DeLillo'srecent novel Point Omega documents this poignantly. His narrator speaks of the "usualterror" of cities with their "endless counting down," with people constantly checkingtheir watches and other time-keeping devices. DeLillo's protagonist moves to the desertwhere "geological time" becomes the paradigm through which a restorative calm isgenerated. Alan Lightman's fiction proves even more relentless in its depiction of thedissociation engendered by an over-reliance on technology. Lightman's protagonist inThe Diagnosis is an information trader who suffers a breakdown and is only restored towell-being through a re-acquaintance with his own natural body rhythms along withthose of the natural world. Many of the characters in the short-story collectionEinstein's Dreams also find that a connection to nature counteracts the senselesscompetition of a consumer-driven, technologically

    Plasmid-encoded addiction genes augment the apparent stability of various low copy number bacterial plasmids by selectively killing plasmid-free (cured) segregants or their progeny. The addiction module of plasmid prophage P1 consists of a pair of genes called phd and doc. Phd serves to prevent host death when the prophage is retained and, should retention mechanisms fail, Doc causes death on curing. Doc acts as a cell toxin to which Phd is an antidote. In this study we show that host mutants...

    Full Text Available To evaluate the Greenspan era, we nevertheless need to address three questions: Is his success due to talent or just luck? Does he have a system of monetary policy or is he himself the system? What will be his legacy? Greenspan was certainly lucky, but he was also clairvoyant. Above all, he has developed a profoundly original monetary policy. His confidence strategy is clearly opposed to the credibility strategy developed in central banks and the academic milieu after 1980, but also inflation targeting, which today constitutes the mainstream monetary policy regime. The question of his legacy seems more nuanced. However, Greenspan will remain 'for a considerable period of time' a highly heterodox and original central banker. His political vision, his perception of an uncertain world, his pragmatism and his openness form the structure of a powerful alternative system, the confidence strategy, which will leave its mark on the history of monetary policy.

    2015-12-01

    Full Text Available Tracking multiple moving targets from a video plays an important role in many vision-based robotic applications. In this paper, we propose an improved Gaussian mixture probability hypothesis density (GM-PHD tracker with weight penalization to effectively and accurately track multiple moving targets from a video. First, an entropy-based birth intensity estimation method is incorporated to eliminate the false positives caused by noisy video data. Then, a weight-penalized method with multi-feature fusion is proposed to accurately track the targets in close movement. For targets without occlusion, a weight matrix that contains all updated weights between the predicted target states and the measurements is constructed, and a simple, but effective method based on total weight and predicted target state is proposed to search the ambiguous weights in the weight matrix. The ambiguous weights are then penalized according to the fused target features that include spatial-colour appearance, histogram of oriented gradient and target area and further re-normalized to form a new weight matrix. With this new weight matrix, the tracker can correctly track the targets in close movement without occlusion. For targets with occlusion, a robust game-theoretical method is used. Finally, the experiments conducted on various video scenarios validate the effectiveness of the proposed penalization method and show the superior performance of our tracker over the state of the art.

    Fernández Gómez, José; Wilson, Zoe A

    2014-08-01

    Controlling pollen development is of major commercial importance in generating hybrid crops and selective breeding, but characterized genes for male sterility in crops are rare, with no current examples in barley. However, translation of knowledge from model species is now providing opportunities to understand and manipulate such processes in economically important crops. We have used information from regulatory networks in Arabidopsis to identify and functionally characterize a barley PHD transcription factor MALE STERTILITY1 (MS1), which expresses in the anther tapetum and plays a critical role during pollen development. Comparative analysis of Arabidopsis, rice and Brachypodium genomes was used to identify conserved regions in MS1 for primer design to amplify the barley MS1 gene; RACE-PCR was subsequently used to generate the full-length sequence. This gene shows anther-specific tapetal expression, between late tetrad stage and early microspore release. HvMS1 silencing and overexpression in barley resulted in male sterility. Additionally, HvMS1 cDNA, controlled by the native Arabidopsis MS1 promoter, successfully complemented the homozygous ms1 Arabidopsis mutant. These results confirm the conservation of MS1 function in higher plants and in particular in temperate cereals. This has provided the first example of a characterized male sterility gene in barley, which presents a valuable tool for the future control of male fertility in barley for hybrid development.

    Full Text Available Recently I completed a performative (creative PhD in the School of Creative Communication (now the Faculty of Design and Creative Practice at the University of Canberra, Australia, where such doctorates were established only in 2002. Since I completed in 2006, I have been contemplating some process issues that emerged during my three and a half year's studies. While conferring with fellow students and colleagues at three universities in England, I found that the many of the problems they encountered were similar and so were not due uniquely to the innovative phase that I encountered, but were part of a wider scenario. At my university, the requirements for a creative doctorate are a creative component (equivalent to about 60,000 words and a theoretical component (exegesis of about 30,000 words. The physical outcome of my thesis is two artist's books: one, Tissue, is autobiographical, while questioning the nature of autobiography, memory and identity. The other, Re-Picturing My Life, is the theoretical component, examining several paradigms including issues of methodology; the value of art as research; theories of memory, identity, autobiography, and human interactions with objects. I have placed some of my text/images in this paper to provide a taste of the work in my thesis. My paper reflects on performative work in the context of academic research, and the resilience, determination and sense of humour needed to complete a doctorate successfully in this valuable area of endeavour.

    Full Text Available In 2008, Amanda Lindhout was kidnapped by a group of extremists while traveling as a freelance journalist in Somalia. She and a colleague were held captive for more than 15 months, released only after their families paid a ransom. In this interview, Amanda discusses her experiences in captivity and her ongoing recovery from this experience with Katherine Porterfield, Ph.D. a clinical psychologist at the Bellevue/NYU Program for Survivors of Torture. Specifically, Amanda describes the childhood experiences that shaped her thirst for travel and knowledge, the conditions of her kidnapping, and her experiences after she was released from captivity. Amanda outlines the techniques that she employed to survive in the early aftermath of her capture, and how these coping strategies changed as her captivity lengthened. She reflects on her transition home, her recovery process, and her experiences with mental health professionals. Amanda's insights provide an example of resilience in the face of severe, extended trauma to researchers, clinicians, and survivors alike. The article ends with an discussion of the ways that Amanda's coping strategies and recovery process are consistent with existing resilience literature. Amanda's experiences as a hostage, her astonishing struggle for physical and mental survival, and her life after being freed are documented in her book, co-authored with Sara Corbett, A House in the Sky.

    Full Text Available A key aspect of the effective supervision of PhD research is the supervisor-student relationship. This interaction is affected by the characteristics and needs of students and institutional conditions, as well as the skills, attitudes, and roles of supervisors and their supervisory styles. When supervision is carried out at a distance, it entails an additional challenge, mainly concerning interaction. The purpose of this study is to improve the research process, supervision, and design of virtual environments in order to support this supervision. The study identifies the supervisory relationships that affect doctoral research conducted at a distance from the student’s academic institution. It also describes how students and their supervisors perceived the characteristics of supervision and the skills and attitudes students perceived in and expected from their supervisors. For data collection, semistructured interviews were used. The results indicate important differences between supervisors’ perceptions concerning their own role and students’ needs regarding supervision, and they demonstrate the importance of attending to student needs and, on the part of supervisors, exercising responsibility in the development of research competencies in students, as is the case of independence of criteria and autonomy.

Research is a primary job for the ones pursuing academic career and statistics is one of the basic components of a research. Metaphor is used as an equivalent to figurative expression (‘mecaz’ in Turkish language. Study group is composed of 19 females (age 27.7 and 40 males (age 30.85 - 59 students in total. Demographic information of participants was collected. Participants were provided with questionnaire in order to assess their metaphorical creation whereby they were asked to fill in the sentence - “statistics is like/ similar to …, because…” - with metaphor. The study has collected total of 59 metaphors in 6 categories. The most created metaphor is in ‘discovering/ revealing’ category. 42.5% of Master’s students and 25% of PhD students are in this category. Metaphors created by graduate students are representing their views about statistics course and hence their view about importance of research. The category ‘discovering/ revealing’, the one with the most created metaphor of this study, is the main concept of science. Consequently, good knowledge of statistics is needed for graduate students to conduct research.

    Fifty-one percent (N = 80) of directors of doctoral PhD and PsyD programs in clinical psychology, accredited by the American Psychological Association (APA), responded to a survey on assessment training. The study was a replication of an earlier survey by Piotrowski and Keller (1984b) on instruction, practices, and attitudes on testing. Our findings indicated that training emphasis in assessment coursework has changed very little over the past decade. Intelligence testing was emphasized in most programs, followed by objective and projective personality assessment. However, training in behavioral assessment techniques was required in only half of the responding programs. There were no significant differences between PhD and PsyD programs concerning required coursework in assessment. Factors that influence the perennial importance of testing in the clinical core curriculum are discussed.

    Full Text Available Öz Erkek egemen toplumlarda kadına yönelik şiddetin kısmi bir kabul gördüğü bilinmektedir. Kadına yönelik şiddetin özel bir şekli de namus cinayetleridir. Son zamanlarda ulusal medyada kendisine oldukça fazla yer bulan namus cinayetleri, sosyolojik çalışmalarda da kendisine yer bulmaya başlamıştır. Bu çalışma, Türkiye’de son zamanlarda oldukça sık tartışılan namus cinayetlerinin sosyal ve kültürel hayattaki durumunu tartışmaya açmaktadır. Çalışma basında yer alan namus cinayetleri ile sınırlıdır. Çalışmada içerik analizi yöntemi kullanılmıştır. Bu bağlamda, Türkiye’de meydana gelen namus cinayetlerinin yoğun olarak ortaya çıktığı bölgelerdeki sosyal sorunlar, farklı bölgelerdeki sosyal yapının namus cinayetlerini nasıl etkilediği, toplumda nasıl yansıma bulduğu ve özellikle kadınlar tarafından nasıl algılandığı konusu, basına yansıyan haberlerin içerik çözümlemesiyle ortaya konulmaya çalışılmıştır. Abstract Violence against women is somewhat acceptable in societies which dominated by the patriarchal system. One of the aspects of violence against women is honor killings. Nowadays, honor killings take place pretty much in Turkish national media. This article discusses the social and cultural basis of honor killings debated quite often recently. The work is limited to honor killings reported by mass media. In the work the content analysis method was used. In this context, social problems and social structures of different regions of Turkey analyzed to determine the source of problem. Additionally, the place of the honor killings, how they come up, and their effects on women and society have been presented with the content analysis of the news on the media.

  7. Reactivity of NHC Alane Adducts towards N-Heterocyclic Carbenes and Cyclic (Alkyl)(amino)carbenes: Ring Expansion, Ring Opening, and Al-H Bond Activation.

    The synthesis of mono-NHC alane adducts of the type (NHC)⋅AlH3 (NHC=Me2 Im (1), Me2 Im(Me) (2), iPr2 Im (3 and [D3 ]-3), iPr2 Im(Me) (4), Dipp2 Im (10); Im=imidazolin-2-ylidene, Dipp=2,6-diisopropylphenyl) and (NHC)⋅AliBu2 H (NHC=iPr2 Im (11), Dipp2 Im (12)) as well as their reactivity towards different types of carbenes is presented. Although the mono-NHC adducts remained stable at elevated temperatures, ring expansion occurred when (iPr2 Im)⋅AlH3 (3) was treated with a second equivalent of the carbene iPr2 Im to give (iPr2 Im)⋅AlH(RER-iPr2 ImH2 ) (6). In 6, {(iPr2 Im}AlH} is inserted into the NHC ring. In contrast, ring opening was observed with the sterically more demanding Dipp2 Im with the formation of (iPr2 Im)⋅AlH2 (ROR-Dipp2 ImH2 )H2 Al⋅(iPr2 Im) (9). In 9, two {(iPr2 Im)⋅AlH2 } moieties stabilize the ring-opened Dipp2 Im. If two hydridic sites are blocked, the adducts are stable with respect to further ring expansion or ring opening, as exemplified by the adducts (iPr2 Im)⋅AliBu2 H (11) and (Dipp2 Im)⋅AliBu2 H (12). The adducts (NHC)⋅AlH3 and (iPr2 Im)⋅AliBu2 H reacted with cAAC(Me) by insertion of the carbene carbon atom into the Al-H bond to give (NHC)⋅AlH2 /iBu2 (cAAC(Me) H) (13-18) instead of ligand substitution, ring-expansion, or ring-opened products. © 2017 Wiley-VCH Verlag GmbH & Co.

    Full Text Available Today’s firms face a new global economy powered by knowledge rather than physical resources and natural raw materials. Universities are crucial actors in ensuring economic development, not only by training highly qualified human capital, but also by producing new knowledge with innovation potential. University–industry research collaborations (UICs have been increaingly recognized as an innovation mode. Highly qualified people, mainly at Ph.D. level, are fundamental for the increase of the knowledge pool from which firms and society as a whole can benefit in terms of the production of innovation. The demand for more specialized researchers in business/industry has led to new versions of doctoral programs, such as Industrial Ph.D. Programs (IPPs, which are well-established in a number of countries. After using an analytical international and comparative education methodology, we have found that the cooperation with industry to develop Ph.D. programs in Colombia is relatively weak and requires to be enhanced. In this paper, we argue for the alignment of the so-called third academic mission of economic development with the traditional academic missions of teaching and research through the implementation of IPPs as a mechanism for strengthening the innovation process of firms and country’s economic growth.

  13. Using Communicative Action Theory to Analyse Relationships Between Supervisors and Phd Students in a Technical University in Sweden

    Directory of Open Access Journals (Sweden)

    Michael Christie

    2013-04-01

    Full Text Available In this paper the authors use the theory of communicative action (Habermas, 1984-6 to analyse problematic relationships that can occur between supervisors and PhD students, between co-supervisors and between the students themselves. In a situation where power is distributed unequally, instrumental and strategic action on the part of either party can complicate and disturb efficacious relationships. We use Flanagan’s critical incident technique (Flanagan, 1954 to analyse twenty-five incidents that are told from a supervisor perspective and twentyfive from a PhD student perspective. The analysis reveals that a large proportion of incidents involved power struggles. Other categories include lack of professional or emotional support and poor communication. Rational dialogue based on Habermasian principles might have avoided many of these problems. The analysis concludes with some practical suggestions as to how the use of communicative action theory and critical incident technique can improve supervision, supervision training and the PhD process.

  14. Adaptive Measurement Partitioning Algorithm for a Gaussian Inverse Wishart PHD Filter that Tracks Closely Spaced Extended Targets

    Directory of Open Access Journals (Sweden)

    P. Li

    2017-06-01

    Full Text Available Use of the Gaussian inverse Wishart probability hypothesis density (GIW-PHD filter has demonstrated promise as an approach to track an unknown number of extended targets. However, when targets of various sizes are spaced closely together and performing maneuvers, estimation errors will occur because measurement partitioning algorithms fail to provide the correct partitions. Specifically, the sub-partitioning algorithm fails to handle cases in which targets are of different sizes, while other partitioning approaches are sensitive to target maneuvers. This paper presents an improved partitioning algorithm for a GIW-PHD filter in order to solve the above problems. The sub-partitioning algorithm is improved by considering target extension information and by employing Mahalanobis distances to distinguish among measurement cells of different sizes. Thus, the improved approach is not sensitive to either differences in target sizes or target maneuvering. Simulation results show that the use of the proposed partitioning approach can improve the tracking performance of a GIW-PHD filter when target are spaced closely together.

    2012-03-01

    New Mexico State University (NMSU) in Las Cruces, NM, is accredited by the Higher Learning Commission (HLC) and a member of the North Central Association of Colleges and Schools (NCA). As part of our continuous accreditation, the physics department annually assesses its progress towards goals and objectives. Our academic goals include the development of skills pertinent to solving advanced problems in physics, a mastery of advanced concepts in physics, an in-depth knowledge of one or more subfields, and develop the ability to conduct original research in a specialization. These goals are supported by objectives, including scientific expertise, advanced training, experimental training, communication skills, and technical know-how. We measure one direct student learning outcome, the ability to solve advanced problems in general physics subjects. The instrument for this measurement is our written physics comprehensive (Ph.D. candidacy) exam, which is administered by an examination committee consisting of all faculty members. We report annually on the percentage of students passing the exam in the various areas (QM, mechanics, E&M, Stat. Mech.). Ineffective preparation of our students in one area would show up by unusually low scores in that area. Since the problems are written and graded by all faculty (not just by those who taught the class), this provides an independent assessment of student learning and also evidence by other professionals skilled in the field. Our examinations are similar to published exams at other institutions. The results of the exam provide feedback to the course instructors, to the students, and to the department head who schedules instructors and courses. In some cases, retaking a course has been a condition of passing the exam for a student. (I acknowledge the efforts of Gary Kyle, who has managed our assessment for many years, and of the entire NMSU physics faculty for contributing to this process.)

    Full Text Available Turkish doctorate programs are mainly composed of course work, preliminary examination, and dissertation stages. In these stages, naturally, several traditions and approaches are followed in different universities and graduate institutes. In this study, it is aimed to identify the main tendencies in preparing PhD dissertations in humanities and social sciences and to analyze the current situation in terms of production of academic knowledge and academic institutionalization in Turkey. Towards, the preparation processes for preliminary examinations and their contents, the procedures for the selection of advisors, dissertation subjects and research methodologies, and rationale for the study subjects, preference of research methodologies and academic writing techniques, and lastly relations with advisors and dissertation committee members are chosen for investigation. Quantitative methodology and survey technique has been used in the study to reach people who have completed their doctoral study on humanities and social sciences in 2011, 2012 and 2013 years in ten Turkish Universities that have given most doctoral graduates in social sciences. 405 people have responded the questionnaire form. The results indicate that the main motive behind selecting dissertation topics is related to career advancement, i.e securing a good position within the university system. Study found that systematic literature review is the most used research methodology and the reading-noting of all related sources than starting to write according to the materials is the most used academic writing technique in dis- sertations. Also, it is found that 1/3 of the participants had no chance to choose his/her advisors. Most of them perceived their relationship with their advisors positively, while admitting that the rate of advisors who actively contributed to the writing process is only 45 %.

    2011-12-01

    Full Text Available Citation practice provides justification for arguments and allows a writer to indicate a rhetorical gap for her/his research and adopt a tone of authority. Claims must be supported with evidence, and writers must demonstrate an understanding of approaches and knowledge in their fields of specialisation, in order to persuade the examiners that the thesis is worthy of the award of a doctorate (Thompson, 2005b. Candidates need to keep the adequate interpersonal relationship with the immediate audience (the examiners. They have to evaluate the previous research in an area of study and to be respectful with previous claims from authorities in the disciplines. They also need to position themselves in relation to other disciplinary members and highlight their individual claims. This paper investigates contrastively how interactional resources of citation and, in particular reporting verbs, are deployed in the literature review chapters of PhD theses written in English and in Spanish.El uso de citas y referencias proporciona una justificación para la argumentaci��n y permite al académico identificar un hueco o espacio retórico donde situar su investigación y adoptar cierto tono de autoridad. Las hipótesis o afirmaciones científicas deben apoyarse en evidencias, y los investigadores deben demostrar un buen conocimiento de los enfoques de su campo de especialización, para así persuadir a los miembros del tribunal examinador de la tesis de que ésta es digna de merecer el doctorado (Thompson, 2005b.

  2. Career Outcomes for Astronomy Ph.D. Graduates of the University of Texas at Austin: The Next Generation

    Science.gov (United States)

    Dinerstein, Harriet L.

    2011-01-01

    Sixteen years ago I conducted a survey of the career trajectories and outcomes of 78 individuals who earned Ph.D.s from the Department of Astronomy at the University of Texas at Austin during the period 1984-1995 (Dinerstein, H. 1996, AAS, 189.0501). In the current poster I extend these statistics up to the present, adding 68 Ph.D. recipients from 1996-2010. This is a sufficiently large sample to search for secular trends such as possible changes in duration of the postdoctoral stage, redistribution of demographics among different kinds of long-term positions, and the emergence of new categories of astronomy-related employment. The picture is less discouraging than one might expect. As of 2010, about 75% of the Texas graduates 7 - 14 years past the Ph.D. are still doing astronomy, and most of those in non-astronomical careers left the field by choice (and often have had considerable success in their alternate careers). Of those 6 years or less past the Ph.D., 50% were in postdoctoral positions and less than 10% had left astronomy. Recent reconsiderations of the employment market (Metcalfe, T.S. 2008, PASP, 120, 229; Seth, A. 2009, Astro2010: The Astronomy and Astrophysics Decadal Survey, Position Paper No. 51) make the point that a typical astronomer who ultimately achieves a permanent position will have held two or three prior temporary positions; this was equally true three decades ago. There has been notable growth nationwide in the number of astronomers employed as faculty at small liberal arts colleges and other undergraduate-centered institutions, a trend that to some degree was anticipated by the University of Texas cohort, which included a number of students for whom this was their personal goal. In a world where job certainty is no longer so prevalent, motivated and resourceful astronomers are finding ways to remain active members of our community.

    According to 2014 findings of the National Research Council, geoscience and related industries indicate an anticipated 48,000 blue-collar, scientific, and managerial positions to be filled by underrepresented minority (URM) workers in the next 15 years. An Information Handling Services (IHS) report prepared for the American Petroleum Institute forecasts even greater numbers estimating upward of 408,000 opportunities for URM workers related to growth in accelerated development of oil, gas and petroleum industries. However, many URM students lack the training in both the hard sciences and craft skills necessary to fill these positions. The Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S) Professional Development Program uses integrative and holistic strategies to better prepare URM students for entry into all levels of the geoscience workforce. Through a three-phase program of mentoring, community building, networking and professional development activities, MS PHD'S promotes collaboration, critical thinking, and soft skills development for participants. Program activities expose URM students to education, training and real-life geoscience workforce experiences while maintaining a continuity of supportive mentoring and training networks via an active virtual community. MS PHD'S participants report increased self-confidence and self-efficacy in pursuing geoscience workforce goals. To date, the program supports 223 participants of who 57, 21 and 16 have received Doctorate, Masters and Baccalaureate degrees respectively and are currently employed within the geoscience and related industries workforce. The remaining 129 participants are enrolled in undergraduate and graduate programs throughout the U.S. Geographic representation of participants includes 35 states, the District of Columbia, Puerto Rico and two international postdoctoral appointments - one in Saudi Arabia and the other in France.

    The intrinsic product polarization and intramolecular isotope effect of the S(1D, 3P)+HD reaction have been investigated on both the lowest singlet state (1A‧) and the triplet state (3A‧ and 3A″) potential energy surfaces by using quasi-classical trajectory and quantum mechanical methods. The calculations indicate that intramolecular isotope effects are different on the three electronic states. The stereodynamics study shows that the P(θr) distributions, P(ϕr) distributions, and polarization-dependent differential cross sections (PDDCSs) (00) are sensitive to mass factor and the product angular momentum vectors are not only aligned but also oriented.

    2011-01-01

    Background Educating nurses to doctoral level is an important means of developing nursing capacity globally. There is an international shortage of doctoral nursing programmes, hence many nurses seek their doctorates overseas. The UK is a key provider of doctoral education for international nursing students, however, very little is known about international doctoral nursing students' learning experiences during their doctoral study. This paper reports on a national study that sought to investigate the learning expectations and experiences of overseas doctoral nursing students in the UK. Methods Semi-structured qualitative interviews were conducted in 2008/09 with 17 international doctoral nursing students representing 9 different countries from 6 different UK universities. Data were analysed thematically. All 17 interviewees were enrolled on 'traditional' 3 year PhD programmes and the majority (15/17) planned to work in higher education institutions back in their home country upon graduation. Results Studying for a UK PhD involved a number of significant transitions, including adjusting to a new country/culture, to new pedagogical approaches and, in some cases, to learning in a second language. Many students had expected a more structured programme of study, with a stronger emphasis on professional nursing issues as well as research - akin to the professional doctorate. Students did not always feel well integrated into their department's wider research environment, and wanted more opportunities to network with their UK peers. A good supervision relationship was perceived as the most critical element of support in a doctoral programme, but good relationships were sometimes difficult to attain due to differences in student/supervisor expectations and in approaches to supervision. The PhD was perceived as a difficult and stressful journey, but those nearing the end reflected positively on it as a life changing experience in which they had developed key professional and

    Full Text Available Nowadays, there is an increasing need of new skills for PhD students to face the future labour market prospects. PhD graduates must have qualities attractive not only in academia but also outside, in both manufacture and service-oriented enterprises, in small innovative companies, and in the civil services and public administration, among others. To know what the needs of these future employees are, is of great importance to be able to improve their personal and academic formation. The aim of this work was, in the framework of the EC-funded ISEKI_Food 4 network, to evaluate the most desirable specific and soft skills that PhD students should acquire by the end of their doctoral studies. To this aim, several surveys were conducted and sent to the different stakeholders (academia and food industry partners in order to collect the information needed. Results showed that competences related to research skills and techniques, research management, personal effectiveness and communication skills were considered to be the most valuable skills to be acquired by our PhD students to meet the future needs of the labour market.  The importance of these skills was appreciated differently, depending on the stakeholder. To sum up, some recommendations to integrate such valuable skills into the curricula of the PhD student are given.

    The MLL1 gene is a frequent target for recurrent chromosomal translocations, resulting in transformation of hematopoietic precursors into leukemia stem cells. Here, we report on structure-function studies that elucidate molecular events in MLL1 binding of histone H3K4me3/2 marks and recruitment of the cyclophilin CyP33. CyP33 contains a PPIase and a RRM domain and regulates MLL1 function through HDAC recruitment. We find that the PPIase domain of CyP33 regulates the conformation of MLL1 through proline isomerization within the PHD3-Bromo linker, thereby disrupting the PHD3-Bromo interface and facilitating binding of the MLL1-PHD3 domain to the CyP33-RRM domain. H3K4me3/2 and CyP33-RRM target different surfaces of MLL1-PHD3 and can bind simultaneously to form a ternary complex. Furthermore, the MLL1-CyP33 interaction is required for repression of HOXA9 and HOXC8 genes in vivo. Our results highlight the role of PHD3-Bromo cassette as a regulatory platform, orchestrating MLL1 binding of H3K4me3/2 marks and cyclophilin-mediated repression through HDAC recruitment.

    The histone lysine demethylase KDM5B regulates gene transcription and cell differentiation and is implicated in carcinogenesis. It contains multiple conserved chromatin-associated domains, including three PHD fingers of unknown function. Here, we show that the first and third, but not the second, PHD fingers of KDM5B possess histone binding activities. The PHD1 finger is highly specific for unmodified histone H3 (H3K4me0), whereas the PHD3 finger shows preference for the trimethylated histone mark H3K4me3. RNA-seq analysis indicates that KDM5B functions as a transcriptional repressor for genes involved in inflammatory responses, cell proliferation, adhesion, and migration. Biochemical analysis reveals that KDM5B associates with components of the nucleosome remodeling and deacetylase (NuRD) complex and may cooperate with the histone deacetylase 1 (HDAC1) in gene repression. KDM5B is downregulated in triple-negative breast cancer relative to estrogen-receptor-positive breast cancer. Overexpression of KDM5B in the MDA-MB 231 breast cancer cells suppresses cell migration and invasion, and the PHD1-H3K4me0 interaction is essential for inhibiting migration. These findings highlight tumor-suppressive functions of KDM5B in triple-negative breast cancer cells and suggest a multivalent mechanism for KDM5B-mediated transcriptional regulation.

    The Arabidopsis thaliana MALE STERILITY1 (MS1) gene encodes a nuclear protein with Leu zipper-like and PHD-finger motifs and is important for postmeiotic pollen development. Here, we examined MS1 function using both cell biological and molecular biological approaches. We introduced a fusion construct of MS1 and a transcriptional repression domain (MS1-SRDX) into wild-type Arabidopsis, and the transgenic plants showed a semisterile phenotype similar to that of ms1. Since the repression domain can convert various kinds of transcriptional activators to dominant repressors, this suggested that MS1 functioned as a transcriptional activator. The Leu zipper-like region and the PHD motif were required for the MS1 function. Phenotypic analysis of the ms1 mutant and the MS1-SRDX transgenic Arabidopsis indicated that MS1 was involved in formation of pollen exine and pollen cytosolic components as well as tapetum development. Next, we searched for MS1 downstream genes by analyzing publicly available microarray data and identified 95 genes affected by MS1. Using a transgenic ms1 plant showing dexamethasone-inducible recovery of fertility, we further examined whether these genes were immediately downstream of MS1. From these results, we discuss a role of MS1 in pollen and tapetum development and the conservation of MS1 function in flowering plants.

    Full Text Available Reperfusion of ischemic cardiac tissue is the standard treatment for improving clinical outcome following myocardial infarction but is inevitably associated with ischemia-reperfusion injury (IRI. Ischemic myocardial injury can be alleviated by exposing the heart to brief episodes of sublethal ischemia-reperfusion prior to the ischemic insult, a phenomenon that has been termed ischemic preconditioning (IPC. Similarly, remote IPC (RIPC is defined as transient episodes of ischemia at a distant site before a subsequent prolonged injury of the target organ. In this setting, adaptive responses to hypoxia/ischemia in peripheral tissues include the release of soluble factors that have the potential to protect cardiomyocytes remotely. Oxygen fluctuation is a hallmark of insufficient tissue perfusion and ischemic episodes. Emerging evidence indicates that prolyl hydroxylase oxygen sensors (PHDs and hypoxia-inducible transcription factors (HIFs are critical regulators of IPC and RIPC. In this minireview, we discuss recent findings concerning the role of the PHD-HIF axis in IPC and RIPC-mediated cardioprotection and examine molecular pathways and cell types that might be involved. We also appraise the therapeutic value of targeting the PHD-HIF axis to enhance cardiac tolerance against IRI.

    2014-01-01

    The academic job market has become increasingly competitive for PhD graduates. In this note, we ask the basic question of 'Are we producing more PhDs than needed?' We take a systems approach and offer a 'birth rate' perspective: professors graduate PhDs who later become professors themselves, an analogue to how a population grows. We show that the reproduction rate in academia is very high. For example, in engineering, a professor in the US graduates 7.8 new PhDs during his/her whole career on average, and only one of these graduates can replace the professor's position. This implies that in a steady state, only 12.8% of PhD graduates can attain academic positions in the USA. The key insight is that the system in many places is saturated, far beyond capacity to absorb new PhDs in academia at the rates that they are being produced. Based on the analysis, we discuss policy implications.

    2013-01-01

    For several decades, a barrier has existed between research and clinical medicine, making it difficult for aspiring scientists to gain exposure to human pathophysiology and access to clinical/translational research mentors during their graduate training. In 2005, the Howard Hughes Medical Institute announced the Med Into Grad initiative to support graduate programs that integrate clinical knowledge into PhD biomedical training, with the goal of preparing a new cadre of translational researchers to work at the interface of the basic sciences and clinical medicine. Two institutions, Baylor College of Medicine and the Cleveland Clinic/Case Western Reserve University, developed new PhD programs in translational biology and/or molecular medicine. These programs teach the topics and skills that today's translational researchers must learn and expose students to clinical medicine. In this article, the authors compare and contrast the history, implementation, and evaluation of the Translational Biology and Molecular Medicine program at Baylor College of Medicine and the Molecular Medicine program at the Cleveland Clinic/Case Western Reserve University. The authors also demonstrate the feasibility of creating a multidisciplinary graduate program in molecular medicine that integrates pathophysiology and clinical medicine without extending training time. They conclude with a discussion of the similarities in training approaches that exist despite the fact that each program was independently developed and offer observations that emerged during their collaboration that may benefit others who are considering developing similar programs.

    In 1960, the first Department of Oral Biology in the United States dedicated to the conduct of research, graduate biomedical research education, and the provision of basic oral science education for the DDS curriculum was established at the University at Buffalo. In 1963, the Department organized the first PhD Program in Oral Biology in the United States. This PhD program has produced a large cadre of oral health researchers, many of whom have gone on to make major contributions to dental research and education. This article provides a brief history of the program, the context within which the program was organized and developed, and a description of some of the many faculty, students, and fellows associated with the program. Additionally, to celebrate the 50th anniversary of this program, a symposium, entitled "The Oral Microbiome, Immunity and Chronic Disease", was held on June 12-14, 2013, in Buffalo, New York. The proceedings are published online in Advances in Dental Research (2014, Vol. 26).

  2. Erythropoietin inhibits HIF-1α expression via upregulation of PHD-2 transcription and translation in an in vitro model of hypoxia-ischemia.

    Hypoxia inducible factor (HIF)-1α is the central transcriptional factor for the regulation of oxygen-associated genes in response to hypoxia. Erythropoietin (EPO), a hematopoietic growth factor, increases oxygen availability during hypoxia/ischemia and is associated with neuroprotection following hypoxia-ischemia in laboratory models of stroke. However, EPO has failed to translate in a clinical setting. Thus, it is critical to elucidate the key players in EPO-induced neuroprotection. Our preliminary studies have shown that EPO, as a downstream gene of HIF, inhibits HIF-1α in a dose-dependent manner in an in vitro model of hypoxia-ischemia. This study is designed to elucidate the primary mediator of EPO-induced HIF-1α inhibition and subsequent cell survival/neuroprotection. Oxygen and glucose deprivation (OGD) of nerve growth factor-differentiated rat pheochromocytoma (PC-12) cells were used to model hypoxia-ischemia in an in vitro environment. The profile of HIF-1α, HIF-2α and prolyl hydroxylase domain 2 (PHD-2) expression; HIF-1α and prolyl hydroxylase (PHD-2) mRNA levels; matrix metalloproteinase (MMP)-9; and cell death was evaluated in the presence and absence of either EPO or PHD-2 inhibitor during OGD. Our findings showed that EPO treatment resulted in an increase in PHD-2 transcription and translation, inhibition of HIF-1α expression, reactive oxygen species formation, and MMP-9 activity, resulting in increased cell survival after OGD. We also observed that EPO-induced cell survival/neuroprotection was reversed by siRNA silencing of PHD-2. This led to the conclusion that PHD-2 is a key mediator of EPO-induced HIF-1α inhibition and subsequent neuroprotection in an in vitro model of hypoxia-ischemia.

    Full Text Available Abstract Public health ethics is neither taught widely in medical schools or schools of public health in the US or around the world. It is not surprising that health care professionals are particularly challenged when faced with ethical questions which extend beyond safeguarding the interests of their individual patients to matters that affect overall public good. The perceived threat of terror after September 11 2007, the anthrax attacks and the Katrina debacle are recent circumstances which may result in coercion. These have piqued the interest of medical professionals and the general public on public health ethics. The Ethics of Coercion in Mass Casualty Medicine written by Griffin Trotter MD, PhD attempts to fill a timely void in this area by examining the ethics of coercion in times of public health disasters.

  8. [Comment on "Meeting Ph.D. Graduates' needs in a changing global environment"] Challenges to fostering interdisciplinary graduate education

    Kock, Beaudry

    C. Susan Weiler's article ("Meeting Ph.D. graduates' needs in a changing global environment," Eos, 55(13), 149, 151) calling for more care and attention to interdisciplinary graduate education illuminated an important and neglected issue. Weiler makes the excellent point that for society to manage complex natural systems effectively, it is imperative that we establish stronger connections between science and public policy. However, as a nation, the United States lacks the institutional research culture to foster this. Nor are we training sufficient numbers of professionals with the skills to make these connections; and when the small number of truly interdisciplinary scientists emerge annually into the workforce, there are few positions that fit them.I echo Weiler's call for increased interdisciplinary collaboration, and the necessary training to support this increase. However, there are some fundamental obstacles her article does not explore.

  9. A PHD in histone language: on the role of histone methylation in plant responses to phosphate deficiency.

    Chandrika, Nulu Naga Prafulla; Sundaravelpandian, Kalaipandian; Schmidt, Wolfgang

    2013-06-01

    Post-translational modifications of core histones are important for various DNA-templated processes such as transcription and repair. We recently reported that the ALFIN LIKE 6 (AL6) gene, identified in a forward genetic screen, is critical for phosphate deficiency-induced root hair formation and several other processes associated with the regulation of cellular phosphate homeostasis. AL6 contains a Plant Homeo Domain (PHD) finger that can bind to trimethylated lysine 4 of histone H3 (H3K4me3). Homozygous mutants defective in AL6 expression form very short root hairs under phosphate-deficient conditions, presumably caused by altered expression of putative primary and secondary down-stream targets of AL6. In this Addendum, we speculate about possible roles of AL6, H3K4 trimethylation and other chromatin modifications in the adaptation of plants to low phosphate availability.

  14. Eco-Driven Chemical Research in the Boundary Between Academia and Industry. PhD Students' Views on Science and Society

    Science.gov (United States)

    Sjöström, Jesper

    2013-10-01

    This paper examines and discusses the views on science and society held among PhD students working in two different industrially and environmentally driven research programmes in the broad area of green chemistry. It is based on thirteen in-depth interviews. The analysis shows three main ways of handling the situation as "post-academic" PhD student: (1) the student sees the PhD work mainly as a job and does not reflect about his/her research or the research funding, (2) the student is satisfied with the post-academic situation, accepts the established innovation policy discourse and is sceptical to traditional academic research, and (3) the student sees collaborative research programmes as a way to get funding, which can be used for secretly done basic research. Most PhD students either emphasise usefulness—in line with the dominating research policy discourse—or they adopt the positivistic view of science as objective and independent of the surrounding society. However, there are only a few signs of "double problematisation", that is a critical view where both disciplinary-oriented and industry-dependent research are problematised.

    Faculty diversity is a longstanding challenge in the US. However, we lack a quantitative and systemic understanding of how the career transitions into assistant professor positions of PhD scientists from underrepresented minority (URM) and well-represented (WR) racial/ethnic backgrounds compare. Between 1980 and 2013, the number of PhD graduates from URM backgrounds increased by a factor of 9.3, compared with a 2.6-fold increase in the number of PhD graduates from WR groups. However, the number of scientists from URM backgrounds hired as assistant professors in medical school basic science departments was not related to the number of potential candidates (R(2)=0.12, p>0.07), whereas there was a strong correlation between these two numbers for scientists from WR backgrounds (R(2)=0.48, pprofessors and posited no hiring discrimination. Simulations show that, given current transition rates of scientists from URM backgrounds to faculty positions, faculty diversity would not increase significantly through the year 2080 even in the context of an exponential growth in the population of PhD graduates from URM backgrounds, or significant increases in the number of faculty positions. Instead, the simulations showed that diversity increased as more postdoctoral candidates from URM backgrounds transitioned onto the market and were hired.

    Recent decades have seen a sharp increase in the number of female PhD graduates in the Netherlands. Currently, the share of females among newly graduated PhDs is almost on par with that of males. A considerable body of scientific studies has investigated the role of gender in the academic workplace. However, the role of gender in the careers of all PhD graduates, including those outside academia, has been studied less. In this study, we investigate gender differences in type of job, occupation, career perception and research performance of recent PhDs. The study is based on a survey of persons who obtained a PhD from one of five Dutch universities between 2008 and early 2012. We show that gender differences in post-PhD careers are non-existent in some aspects studied, but there are small differences in other aspects, such as sector of employment, type of contract, involvement in teaching and management, and career perception. In contrast, male and female PhDs differ sharply on two factors. The first is field of PhD, females being heavily underrepresented in engineering and the natural sciences. The second is part-time employment, females being much more likely to work part-time than males, especially if they work in the Netherlands. In later career stages, the combination of the small and large differences can be presumed to affect the career progression of female PhDs through cumulative disadvantage.

    SUMMARY The histone lysine demethylase KDM5B regulates gene transcription and cell differentiation. It contains three PHD fingers, the biological roles of which remain elusive. Here, we show that the first PHD1 finger of KDM5B binds unmodified histone H3, whereas the third PHD3 finger prefers the trimethylated mark, H3K4me3. RNA-seq analysis indicates that KDM5B functions as a transcriptional repressor for a set of genes. Biochemical analysis reveals that KDM5B associates with components of the nucleosome remodeling and deacetylase (NuRD) complex and may cooperate with HDAC1 in gene repression. Compared with the estrogen receptor positive breast cancers, KDM5B is downregulated in the triple-negative breast cancer. Overexpression of KDM5B in the MDA-MB 231 breast cancer cells suppresses cell migration and invasion ability, and the PHD1-H3K4me0 interaction is important for inhibition of migration. These findings highlight tumor-suppressive functions of KDM5B in triple-negative breast cancer cells and suggest a novel multivalent mechanism for KDM5B-mediated transcriptional regulation.

  11. Functional validation of putative toxin-antitoxin genes from the Gram-positive pathogen Streptococcus pneumoniae: phd-doc is the fourth bona-fide operon

    Directory of Open Access Journals (Sweden)

    Wai Ting eChan

    2014-12-01

    Full Text Available Bacterial toxin-antitoxin (TAs loci usually consist of two genes organized as an operon, where their products are bound together and inert under normal conditions. However, under stressful circumstances the antitoxin, which is more labile, will be degraded more rapidly, thereby unleashing its cognate toxin to act on the cell. This, in turn, causes cell stasis or cell death, depending on the type of TAs and/or time of toxin exposure. Previously based on in silico analyses, we proposed that Streptococcus pneumoniae, a pathogenic Gram-positive bacterium, may harbor between four to ten putative TA loci depending on the strains. Here we have chosen the pneumococcal strain Hungary19A-6 which contains all possible ten TA loci. In addition to the three well-characterized operons, namely relBE2, yefM-yoeB, and pezAT, we show here the functionality of a fourth operon that encodes the pneumococcal equivalent of the phd-doc TA. Transcriptional fusions with gene encoding Green Fluorescent Protein showed that the promoter was slightly repressed by the Phd antitoxin, and exhibited almost background values when both Phd-Doc were expressed together. These findings demonstrate that phd-doc shows the negative self-regulatory features typical for an authentic TA. Further, we also show that the previously proposed TAs XreA-Ant and Bro-XreB, although they exhibit a genetic organization resembling those of typical TAs, did not appear to confer a functional behavior corresponding to bona fide TAs. In addition, we have also discovered new interesting bioinformatics results for the known pneumococcal TAs RelBE2 and PezAT. A global analysis of the four identified toxins-antitoxins in the pneumococcal genomes (PezAT, RelBE2, YefM-YoeB, and Phd-Doc showed that RelBE2 and Phd-Doc are the most conserved ones. Further, there was good correlation among TA types, clonal complexes and sequence types in the 48 pneumococcal strains analyzed.

  12. Outcomes assessment of science & engineering doctor of philosophy (Ph.D.) programs: An exploratory study of prospective influencers in distinguished graduate placement

    Science.gov (United States)

    Williamson, Louise M.

    This exploratory study was an investigation of the mission and emphases of twenty-two science & engineering doctor of philosophy (Ph.D.) programs in ten fields of study at nine public research universities in the United States and the corresponding influence those factors impose on placement of Ph.D. graduates of those programs into academic program settings. Ph.D. program chairs participated via protocol to provide descriptive, statistical, and experiential details of their Ph.D. programs and offered insight on current conditions for academic placement opportunities. The quantitative analysis served as the basis of examination of influencers in graduate placement for those Ph.D. programs that are informed about placement activity of their graduates. Among the nine tested hypotheses there were no statistically significant findings. The qualitative expressions of this study---those found in the confounding variables, the limitations of the study, those questions that elicited opinions and further discussion and follow-up queries with program chairs---added most meaningfully, however, to the study in that they served as a gauge of the implications of neglect for those Ph.D. programs that remain uninformed about their graduate placement activity. Central to the findings of this study was that one compelling fact remains the same. Denecke, Director of Best Practice at the Council of Graduate Schools, pointed out years ago that just as "we know very little about why those who finish and why those who leave do so, we also know surprisingly little about where students go after their degrees...we therefore have little information about how effective doctoral programs are in preparing doctorates for short- and long-term career success." The fact remains that the effectiveness of doctoral programs in the context of career success is just as uncertain today. A serious admonition is that one-half of those programs that participated in this study remain uninformed about the

During the early theoretical research, on the base of empirical study and behavioristic methods, he revealed and summed up the elementary facts American democracy occurred and devel-oped, that was, the social organizations represented by interest groups shared the civil power and the society restricted power. By virtue of these facts, the democracy has been effectively maintained and improved. Dahl’ s democratic theory has the important enlightenment and reference value for exploring the social governance path and accumulating social governance experiences.

    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.

    There is a growing need for doctoral-prepared allied health professionals in health care practice, research, and teaching. This paper describes the development and evolution of the PhD Program in Health Related Sciences at Virginia Commonwealth University, which was designed to meet the demand for flexible learning environments by working allied health professionals. The program, now on its 14th year, offers interdisciplinary education in allied health fields through a blended learning environment that includes online and on-site education. An alumni assessment of the program was conducted in 2006 and 2008 to understand how well the program trained its graduates and how well the program responded to the needs of students. Six primary areas were reviewed: 1) extent to which program goals were achieved, 2) general skills and knowledge development for the student, 3) adequacy of the advising function of the program, 4) specific skill development for the student, 5) adequacy of instructional technology, and 6) impressions of the overall program. Findings from the alumni assessment led to changes in curriculum, enhanced use of distance education teaching, additional instructor training on distance-based multimedia technologies, and enhanced student-faculty interaction. Assessment of this program identified key areas, such as technology support, student-student interaction, and student-instructor interaction, which should be emphasized in the development or redesign of allied health educational programs offered in blended learning formats.

  20. The Histone Demethylase KDM5 Activates Gene Expression by Recognizing Chromatin Context through Its PHD Reader Motif

    Directory of Open Access Journals (Sweden)

    Xingyin Liu

    2015-12-01

    Full Text Available KDM5 family proteins are critically important transcriptional regulators whose physiological functions in the context of a whole animal remain largely unknown. Using genome-wide gene expression and binding analyses in Drosophila adults, we demonstrate that KDM5 (Lid is a direct regulator of genes required for mitochondrial structure and function. Significantly, this occurs independently of KDM5’s well-described JmjC domain-encoded histone demethylase activity. Instead, it requires the PHD motif of KDM5 that binds to histone H3 that is di- or trimethylated on lysine 4 (H3K4me2/3. Genome-wide, KDM5 binding overlaps with the active chromatin mark H3K4me3, and a fly strain specifically lacking H3K4me2/3 binding shows defective KDM5 promoter recruitment and gene activation. KDM5 therefore plays a central role in regulating mitochondrial function by utilizing its ability to recognize specific chromatin contexts. Importantly, KDM5-mediated regulation of mitochondrial activity is likely to be key in human diseases caused by dysfunction of this family of proteins.

    Equitable gender representation is an important aspect of scientific workforce development to secure a sufficient number of individuals and a diversity of perspectives. Biology is the most gender equitable of all scientific fields by the marker of degree attainment, with 52.5% of PhDs awarded to women. However, equitable rates of degree completion do not translate into equitable attainment of faculty or postdoctoral positions, suggesting continued existence of gender inequalities. In a national cohort of 336 first-year PhD students in the biological sciences (i.e., microbiology, cellular biology, molecular biology, developmental biology, and genetics) from 53 research institutions, female participants logged significantly more research hours than males and were significantly more likely than males to attribute their work hours to the demands of their assigned projects over the course of the academic year. Despite this, males were 15% more likely to be listed as authors on published journal articles, indicating inequality in the ratio of time to credit. Given the cumulative advantage that accrues for students who publish early in their graduate careers and the central role that scholarly productivity plays in academic hiring decisions, these findings collectively point to a major potential source of persisting underrepresentation of women on university faculties in these fields.

    Preparing nursing doctoral students with knowledge and skills for developing science, stewarding the discipline, and educating future researchers is critical. This study examined the content of 120 U.S. PhD programs in nursing as communicated on program websites in 2012. Most programs included theory, research design, and statistics courses. Nursing inquiry courses were evidenced on only half the websites. Course work or research experiences in informatics were mentioned on 22.5% of the websites; biophysical measurement and genetics/genomics were mentioned on fewer than 8% of program websites. Required research experiences and instruction in scientific integrity/research ethics were more common when programs had Institutional Training Award funding (National Institutes of Health T32 mechanism) or were located at a university with a Clinical and Translational Science Award. Changes in education for the next generation of PhD students are critically needed to support advancement of nursing science. Copyright © 2015 Elsevier Inc. All rights reserved.

    In a survey of all PhD programs in psychology in the United States and Canada, the authors documented the quantitative methodology curriculum (statistics, measurement, and research design) to examine the extent to which innovations in quantitative methodology have diffused into the training of PhDs in psychology. In all, 201 psychology PhD programs (86%) participated. This survey replicated and extended a previous survey (L. S. Aiken, S. G. West, L. B. Sechrest, & R. R. Reno, 1990), permitting examination of curriculum development. Most training supported laboratory and not field research. The median of 1.6 years of training in statistics and measurement was mainly devoted to the modally 1-year introductory statistics course, leaving little room for advanced study. Curricular enhancements were noted in statistics and to a minor degree in measurement. Additional coverage of both fundamental and innovative quantitative methodology is needed. The research design curriculum has largely stagnated, a cause for great concern. Elite programs showed no overall advantage in quantitative training. Forces that support curricular innovation are characterized. Human capital challenges to quantitative training, including recruiting and supporting young quantitative faculty, are discussed. Steps must be taken to bring innovations in quantitative methodology into the curriculum of PhD programs in psychology.

    Full Text Available Abstract Background Accumulated evidence suggest that specific patterns of histone posttranslational modifications (PTMs and their crosstalks may determine transcriptional outcomes. However, the regulatory mechanisms of these "histone codes" in plants remain largely unknown. Results In this study, we demonstrate for the first time that a salinity stress inducible PHD (plant homeodomain finger domain containing protein GmPHD5 can read the "histone code" underlying the methylated H3K4. GmPHD5 interacts with other DNA binding proteins, including GmGNAT1 (an acetyl transferase, GmElongin A (a transcription elongation factor and GmISWI (a chromatin remodeling protein. Our results suggest that GmPHD5 can recognize specific histone methylated H3K4, with preference to di-methylated H3K4. Here, we illustrate that the interaction between GmPHD5 and GmGNAT1 is regulated by the self-acetylation of GmGNAT1, which can also acetylate histone H3. GmGNAT1 exhibits a preference toward acetylated histone H3K14. These results suggest a histone crosstalk between methylated H3K4 and acetylated H3K14. Consistent to its putative roles in gene regulation under salinity stress, we showed that GmPHD5 can bind to the promoters of some confirmed salinity inducible genes in soybean. Conclusion Here, we propose a model suggesting that the nuclear protein GmPHD5 is capable of regulating the crosstalk between histone methylation and histone acetylation of different lysine residues. Nevertheless, GmPHD5 could also recruit chromatin remodeling factors and transcription factors of salt stress inducible genes to regulate their expression in response to salinity stress.

  6. In what ways do the experiences of students in PhD programs in the molecular biosciences foster knowledge transfer?

    Prevost, Amy C.

    Doctoral training in the molecular biosciences often fails to prepare students for academic and alternate careers. Several studies of doctoral training have reported a need to improve doctoral education; outlining specific criticisms related to the need to broaden the scope of the doctoral degree in order to prepare students for careers. The development of doctoral students' knowledge transfer skills is the key to making this transition. The theory advanced in this study extends the literature on doctoral education related to student experiences that foster the development of knowledge transfer skills. These insights will be a resource for academic leaders as they develop new programs and the re-develop existing ones; to students and graduates as they become leaders in their field; and to mentors, who have a large role in the development of doctoral students. Research conducted for this dissertation led to the development of theory about elements of the doctoral experience that foster the development of knowledge transfer skills in the molecular biosciences. In exploring ways the experiences of students in PhD programs in the molecular biosciences foster knowledge transfer, I was able to develop a framework for understanding these experiences in the context of doctoral programs. Students' experiences are affected by different elements of doctoral education. As they develop identities as researchers and scientists, and transition from novices to experts, students' experiences are shaped by their mentors, peers, programs and departments. Subjects spoke about their experiences in interviews. This study exposed a need to balance support and challenge for doctoral students to allow them to develop the capacity to perform scientific research and act as leaders. The development of knowledge transfer skills within this context is important preparation for students in the molecular biosciences. Doctoral students in this area need to apply their expertise in increasingly

    Equitable gender representation is an important aspect of scientific workforce development to secure a sufficient number of individuals and a diversity of perspectives. Biology is the most gender equitable of all scientific fields by the marker of degree attainment, with 52.5% of PhDs awarded to women. However, equitable rates of degree completion do not translate into equitable attainment of faculty or postdoctoral positions, suggesting continued existence of gender inequalities. In a national cohort of 336 first-year PhD students in the biological sciences (i.e., microbiology, cellular biology, molecular biology, developmental biology, and genetics) from 53 research institutions, female participants logged significantly more research hours than males and were significantly more likely than males to attribute their work hours to the demands of their assigned projects over the course of the academic year. Despite this, males were 15% more likely to be listed as authors on published journal articles, indicating inequality in the ratio of time to credit. Given the cumulative advantage that accrues for students who publish early in their graduate careers and the central role that scholarly productivity plays in academic hiring decisions, these findings collectively point to a major potential source of persisting underrepresentation of women on university faculties in these fields. © 2017 D.

    The core of evidence-based practice (EBP) as advocated for within the practice arms of the health and social sciences is to promote the routine incorporation of the best available research evidence into practice efforts. This requires discipline-specific education that is not only grounded in professional practice but also prepares would-be scientists in the application of the sophisticated techniques that characterize today's high research standards. Doctoral-level education is an important primer for future scientific endeavors across disciplines. This study examined 2334 theses published across Sweden in public health, criminology, nursing, psychiatry, psychology, social work, and sociology during the period 1997-2012. Of the theses reviewed, 13% aimed to investigate the effects of interventions. The highest percentage of effectiveness studies was found in nursing, public health, and psychology. The percentage of outcome research increased during the period. Controlled studies (with comparison group and pre- and post-test) occurred primarily within public health, nursing, psychiatry, and psychology. Of the 296 theses that included an intervention effectiveness study, 131 (44%), or 5.6% of all theses reviewed, met all four assessment criteria for quality. PhD education across seven disciplines in Sweden may be producing a professional core of scientists that is ill prepared to produce the type of research that is necessary to inform practice of the effects of its interventions as exposure to the rigors of quality effectiveness research is all but non-existent. This has implications for the advancement of an evidence-based practice and intervention science more broadly.

  9. The methyltransferase NSD3 has chromatin-binding motifs, PHD5-C5HCH, that are distinct from other NSD (nuclear receptor SET domain) family members in their histone H3 recognition.

    The NSD (nuclear receptor SET domain-containing) family members, consisting of NSD1, NSD2 (MMSET/WHSC1), and NSD3 (WHSC1L1), are SET domain-containing methyltransferases and aberrant expression of each member has been implicated in multiple diseases. They have specific mono- and dimethylase activities for H3K36, whereas play nonredundant roles during development. Aside from the well characterized catalytic SET domain, NSD proteins have multiple potential chromatin-binding motifs that are clinically relevant, including the fifth plant homeodomain (PHD5) and the adjacent Cys-His-rich domain (C5HCH) located at the C terminus. Herein, we report the crystal structures of the PHD5-C5HCH module of NSD3, in the free state and in complex with H3(1-7) (H3 residues 1-7), H3(1-15) (H3 residues 1-15), and H3(1-15)K9me3 (H3 residues 1-15 with trimethylation on K9) peptides. These structures reveal that the PHD5 and C5HCH domains fold into a novel integrated PHD-PHD-like structural module with H3 peptide bound only on the surface of PHD5 and provide the molecular basis for the recognition of unmodified H3K4 and trimethylated H3K9 by NSD3 PHD5. Structural studies and binding assays show that differences exist in histone binding specificity of the PHD5 domain between three members of the NSD family. For NSD2, the PHD5-C5HCH:H3 N terminus interaction is largely conserved, although with a stronger preference for unmethylated H3K9 (H3K9me0) than trimethylated H3K9 (H3K9me3), and NSD1 PHD5-C5HCH does not bind to H3 peptides. Our results shed light on how NSD proteins that mediate H3K36 methylation are localized to specific genomic sites and provide implications for the mechanism of functional diversity of NSD proteins.

    2013-12-01

    Full Text Available “Time” magazine chose Albert Einstein as “Person of the Century.” This was undoubtedly a reasonable choice, but as I will argue in this article, there are also good reasons for contending that Turing might have received this honor. One such reason I consider here is his purely scientific work, which stems from the greatest mathematical tradition, and how it affected the development of mathematics itself and was finally instrumental in shaping a new technological world. This is true both as regards the computation and treatment of information as well as the establishment of new forms of social relations. In relation to the foregoing, we have Turing’s contributions to the deciphering of secret codes during the Second World War, which in a somewhat metaphorical sense may be regarded as a new tool for undermining personal privacy, that civil right whose denial finally ruined his lifeEn diciembre de 1999, la revista Time eligió a Albert Einstein “The Person of the Century”. Fue, no cabe duda, una elección razonable, pero, como se argumenta en este artículo, existen también buenos argumentos para sostener que Turing podría haber recibido tal honor. En apoyo de semejante tesis están sus trabajos puramente científicos, que se esbozan aquí, trabajos que entroncan con la mejor tradición matemática, y cómo afectaron al desarrollo matemático, siendo finalmente instrumentales en la configuración de un nuevo mundo tecnológico, tanto en lo que al cálculo y manejo de información se refiere, como en lo relativo al establecimiento de nuevas formas de relaciones sociales. Relacionadas con lo anterior, se encuentran las aportaciones que hizo durante la Segunda Guerra Mundial al desciframiento de códigos secretos, que, en cierto sentido, metafórico, se pueden considerar como una nueva herramienta para socavar la privacidad, ese derecho civil cuya negación arruinó su propia vida.

    The 75th anniversary of Turing's seminal paper and his centennial year anniversary occur in 2011 and 2012, respectively. It is natural to review and assess Turing's contributions in diverse fields in the light of new developments that his thoughts has triggered in many scientific communities. Here, the main idea is to discuss how the work of Turing allows us to change our views on the foundations of Mathematics, much like quantum mechanics changed our conception of the world of Physics. Basic notions like computability and universality are discussed in a broad context, making special emphasis on how the notion of complexity can be given a precise meaning after Turing, i.e., not just qualitative but also quantitative. Turing's work is given some historical perspective with respect to some of his precursors, contemporaries and mathematicians who took up his ideas farther.

    Johnson, James V; Jeske, Arthur H

    2011-12-01

    Many lessons can be learned from the career of Dr. Sumter Arnim, chief among them that we have a professional obligation to apply scientific knowledge to the practice of dentistry and to involve our patients in their dental care, and to share this translational knowledge with one's colleagues. Arnim's work was an honor not only for the University of Texas Dental Branch (now, The University of Texas School of Dentistry at Houston), but for every school and student with whom he interacted. Our profession is better for having had Sumter Arnim as one of its members, and he can be credited with having played a leadership role in what is now known as evidence-based dentistry in Texas, the United States, and beyond. One of the authors of this paper (JVJ) had the opportunity to be a student at the University of Texas Dental Branch during the time that Dr. Sumter Arnim was faculty member. Dr. Arnim was deservedly respected by his students and faculty colleagues alike, due in no small part to his dedication to dentistry. This dedication to the profession was well known, as Dr. Arnim had been accepted to Yale University Medical School, but soon after enrollment there, he elected to pursue a Ph.D. degree in Pathology, rather than M.D. Dr. Arnim constantly stressed the bacteriologic nature of dental disease and the value of prevention to his Dental Branch students, serving as Director of the Postgraduate School with great distinction. His steadfast belief in the biological basis of dentistry was manifest in his frequent admonition to the student body: "You can either be doctors or hardware merchants." Finally, it is ironic that in 2011, the American Dental Association has reiterated some of Arnim's career themes in its current publication on barriers to oral health in the United States, with primary messages that include, "Prevention is essential. A public health model based on the surgical intervention in disease that could have been prevented after that disease has occurred

  6. Career Coaches as a Source of Vicarious Learning for Racial and Ethnic Minority PhD Students in the Biomedical Sciences: A Qualitative Study

    2016-01-01

    Introduction Many recent mentoring initiatives have sought to help improve the proportion of underrepresented racial and ethnic minorities (URMs) in academic positions across the biomedical sciences. However, the intractable nature of the problem of underrepresentation suggests that many young scientists may require supplemental career development beyond what many mentors are able to offer. As an adjunct to traditional scientific mentoring, we created a novel academic career “coaching” intervention for PhD students in the biomedical sciences. Objective To determine whether and how academic career coaches can provide effective career-development-related learning experiences for URM PhD students in the biomedical sciences. We focus specifically on vicarious learning experiences, where individuals learn indirectly through the experiences of others. Method The intervention is being tested as part of a longitudinal randomized control trial (RCT). Here, we describe a nested qualitative study, using a framework approach to analyze data from a total of 48 semi-structured interviews from 24 URM PhD students (2 interviews per participant, 1 at baseline, 1 at 12-month follow-up) (16 female, 8 male; 11 Black, 12 Hispanic, 1 Native-American). We explored the role of the coach as a source of vicarious learning, in relation to the students’ goal of being future biomedical science faculty. Results Coaches were resources through which most students in the study were able to learn vicariously about how to pursue, and succeed within, an academic career. Coaches were particularly useful in instances where students’ research mentors are unable to provide such vicarious learning opportunities, for example because the mentor is too busy to have career-related discussions with a student, or because they have, or value, a different type of academic career to the type the student hopes to achieve. Implications Coaching can be an important way to address the lack of structured career

  7. Biomedical Ph.D. students enrolled in two elite universities in the United kingdom and the United States report adopting multiple learning relationships.

    Matthew W Kemp

    Full Text Available The ability to form multiple learning relationships is a key element of the doctoral learning environment in the biomedical sciences. Of these relationships, that between student and supervisor has long been viewed as key. There are, however, limited data to describe the student perspective on what makes this relationship valuable. In the present study, we discuss the findings of semi-structured interviews with biomedical Ph.D. students from the United Kingdom and the United States to: i determine if the learning relationships identified in an Australian biomedical Ph.D. cohort are also important in a larger international student cohort; and ii improve our understanding of student perceptions of value in their supervisory relationships.32 students from two research intensive universities, one in the United Kingdom (n = 17, and one in the United States (n = 15 were recruited to participate in a semi-structured interview. Verbatim transcripts were transcribed, validated and analysed using a Miles and Huberman method for thematic analysis.Students reported that relationships with other Ph.D. students, post-doctoral scientists and supervisors were all essential to their learning. Effective supervisory relationships were perceived as the primary source of high-level project guidance, intellectual support and confidence. Relationships with fellow students were viewed as essential for the provision of empathetic emotional support. Technical learning was facilitated, almost exclusively, by relationships with postdoctoral staff.These data make two important contributions to the scholarship of doctoral education in the biomedical sciences. Firstly, they provide further evidence for the importance of multiple learning relationships in the biomedical doctorate. Secondly, they clarify the form of a 'valued' supervisory relationship from a student perspective. We conclude that biomedical doctoral programs should be designed to contain a minimum level

    Bromodomain functions as the acetyl-lysine binding domains to regulate gene transcription in chromatin. Bromodomains are rapidly emerging as new epigenetic drug targets for human diseases. However, owing to their transient nature and modest affinity, histone-binding selectivity of bromodomains has remained mostly elusive. Here, we report high-resolution crystal structures of the bromodomain-PHD tandem module of human transcriptional coactivator CBP bound to lysine-acetylated histone H4 peptides. The structures reveal that the PHD finger serves a structural role in the tandem module and that the bromodomain prefers lysine-acetylated motifs comprising a hydrophobic or aromatic residue at -2 and a lysine or arginine at -3 or -4 position from the acetylated lysine. Our study further provides structural insights into distinct modes of singly and diacetylated histone H4 recognition by the bromodomains of CBP and BRD4 that function differently as a transcriptional coactivator and chromatin organizer, respectively, explaining their distinct roles in control of gene expression in chromatin.

    Bacterial toxin-antitoxin (TA) systems serve a variety of physiological functions including regulation of cell growth and maintenance of foreign genetic elements. Sequence analyses suggest that TA families are linked by complex evolutionary relationships reflecting likely swapping of functional domains between different TA families. Our crystal structures of Phd-Doc from bacteriophage P1, the HigA antitoxin from Escherichia coli CFT073, and YeeU of the YeeUWV systems from E. coli K12 and Shigella flexneri confirm this inference and reveal additional, unanticipated structural relationships. The growth-regulating Doc toxin exhibits structural similarity to secreted virulence factors that are toxic for eukaryotic target cells. The Phd antitoxin possesses the same fold as both the YefM and NE2111 antitoxins that inhibit structurally unrelated toxins. YeeU, which has an antitoxin-like activity that represses toxin expression, is structurally similar to the ribosome-interacting toxins YoeB and RelE. These observations suggest extensive functional exchanges have occurred between TA systems during bacterial evolution.

    近35年来,随着美国少数族裔作家(包括非洲裔美国作家)在"美国性"定义问题上的重要性日益突显,美国文学研究的重心发生了深刻的变化.到底是什么构成了"非洲裔美国人身份或黑人身份"?这一问题在非洲裔美国文学内部引发了激烈的对话,而在诺贝尔文学奖得主托妮·莫里森和普利策小说奖得主詹姆士·阿兰·麦克斐逊的小说中,这类讨论显得尤为深刻.本文通过细读莫里森的小说《柏油娃》和麦克斐逊的两篇短篇小说,即"我为什么喜欢乡村音乐"和"活动空间",探讨其中隐含的关于种族真实性问题的争论.本文的中心论点是,作品通过旅行而不是通过对种族概念的抽象化,传达出作品人物对自己身份和身份归宿的理解.就本质而言,这些故事是在对一个观念进行言说,即身份是一个过程问题而不是位置问题.%American literary studies have witnessed a profound shift in emphasis over the last thirty five years in the United States, with minority writers, including African American writers, taking a more prominent role in defining what it means to be American.We also find within African American literature, there has come to be a vigorous dialogue as to what constitutes an authentic African American, or black, identity.This discussion has been especially profound in the fictions of Nobel Laureate, Toni Morrison, and the Pulitzer-Prize-winning fiction writer, James Alan McPherson.This essay seeks to examine this struggle over issues of racial authenticity by examining Morrison's 1980 novel, Tar Baby, and two short stories by McPherson, "Why I Like Country Music" and "Elbow Room." At the center of the argument is that it is travel, not an essentialized notion of race, that informs the characters' understanding of who they are and who they can be.In essence, the stories speak to the notion that identity is a matter of process, not location.

Like for NSC, the epidermal growth factor receptor (EGFR) and Notch receptor signaling pathways are believed to be important for the maintenance of bCSC. These pathways as such present promising targets in a future anti-bCSC GBM...... treatment. The overall aim of the present PhD project has been to study the functional role of EGFR and Notch activity in bCSCs stem cell-like features and tumorigenic potential with the purpose of deepen our knowledge about the significance of these pathways in the bCSC population in GBM. By establishing...... and culturing human derived GBM xenograft cells under NSC conditions we obtained neurosphere cultures that contained cells with stem cell-like and tumorigenic properties. We moreover characterized the different cultures based on their expression level of the EGFR and Notch receptor as well as the expression...
