description: We present a review of the field of formaldehyde (H2CO) 6cm masers in the Galaxy. Previous to our ongoing work, H2CO 6cm masers had been detected in the Galaxy only toward three regions: NGC7538 IRS1, Sgr B2, and G29.96-0.02. Current efforts by our group using the Very Large Array, Arecibo, and the Green Bank Telescope have resulted in the detection of four new H2CO 6cm maser regions. We discuss the characteristics of the known H2CO masers and the association of H2CO 6cm masers with very young regions of massive star formation. We also review the current ideas on the pumping mechanism for H2CO 6cm masers.

description: Matter-light quantum interface and quantum memory for light are important ingredients of quantum information protocols, such as quantum networks, distributed quantum computation, etc. In this Letter we present a spatially multimode scheme for quantum memory for light, which we call a quantum hologram. Our approach uses a multi-atom ensemble which has been shown to be efficient for a single spatial mode quantum memory. Due to the multi-atom nature of the ensemble it is capable of storing many spatial modes, a feature critical for the present proposal. A quantum hologram has a higher storage capacity compared to a classical hologram, and is capable of storing quantum features of an image, such as multimode superposition and entangled quantum states, something that a standard hologram is unable to achieve. Due to optical parallelism, the information capacity of the quantum hologram will obviously exceed that of a single-mode scheme.

description: We propose the use of algebras of generalized functions for the analysis of certain highly singular problems in the calculus of variations. After a general study of extremal problems on open subsets of Euclidean space in this setting we introduce the first and second variation of a variational problem. We then derive necessary (Euler-Lagrange equations) and sufficient conditions for extremals. The concept of association is used to obtain connections to a distributional description of singular variational problems. We study variational symmetries and derive an appropriate version of Nöther's theorem. Finally, a number of applications to geometry, mechanics, elastostatics and elastodynamics are presented.

description: Prices of commodities or assets produce what is called time-series. Different kinds of financial time-series have been recorded and studied for decades. Nowadays, all transactions on a financial market are recorded, leading to a huge amount of data available, either for free in the Internet or commercially. Financial time-series analysis is of great interest to practitioners as well as to theoreticians, for making inferences and predictions. Furthermore, the stochastic uncertainties inherent in financial time-series and the theory needed to deal with them make the subject especially interesting not only to economists, but also to statisticians and physicists. While it would be a formidable task to make an exhaustive review on the topic, with this review we try to give a flavor of some of its aspects.

description: We present two methods for constructing a flat band (FB) system having a flat energy dispersion over the entire Brillouin zone within tight-binding model, where the resulting Hamiltonian may not be easily obtained by existing methods based on a bipartite graph and line graph techniques. In the first method, we derive a set of conditions equivalent to the appearance of FBs for a given graph structure. This method allows parameter to be tuned so that systems with a small number of sites per unit cell has a FB. In the second method, we show that FB systems can be obtained by removing or adding sites to an existing FB system under specific rules. In particular, the site addition method enables us to construct multiple FB systems stemming from a single FB system. The FB system obtained by the second method has the characteristics that the component ratios in the FB eigenstate are partially common to the original system. We illustrate how lattices having a FB can be constructed by applying the latter method starting from an existing lattice such as a kagome lattice, demonstrating that a wide variety of lattices can possess a FB in the band structure.

description: Trust in political institutions is an integral component of societal cohesion. Institutional trust is essential to maintaining legitimacy of the democratic institutions and support for political reforms across European societies. The recent economic and financial crisis of 2008-2009 and the austerity policies that followed have contributed to the rising inequality within and between European countries. Although some European societies have proven to be more resilient to the effects of the crisis, many others have experienced rapid economic and social decline. Furthermore, policy responses adopted by a number of countries to counteract the consequences of the crisis have resulted in severe cuts in social expenditures further contributing to the decline in well-being and trust of their citizens. This policy brief summarizes the main findings of the RE-InVEST report titled "Economic crisis, vulnerability and institutional trust". All the analyses were based on the individual survey data from the European Social Survey (ESS) covering the period from 2002 to 2012.
Re-Focusing Social Investment on Capabilities and Human Rights

description: In 2012 the Committee on Employment and Social Affairs of the European Parliament approved a "Social Investment Pact" as a response to the crisis, thereby encouraging the European Commission and the Member States to embrace the social investment approach to welfare reform. In the document it is argued that the economic crisis requires a "modernization" of the European Social Model and national social policies, transforming welfare states from institutions "that mainly respond to damages caused by market failure" into "activating welfare states", that "invest in people and provide instruments and incentives with a view to create sustainable jobs and growth as well as prevent social distortions". Thus, social investment aims at "preparing individuals, families and societies to adapt to changing economic conditions and labor market demands", contributing "to reassure a proper employment level in the future and to improve Europe’s competitiveness"1. In the social investment perspective, governments should treat social policies not primarily as spending but rather "as investments that will give real return in

Responding to the initiative by the European Parliament, the European Commission adopted in 2013 a "Social Investment Package" aimed at influencing the content of the European Semester, promoting a focus on social investment and active inclusion in country specific recommendations3. The twofold aim of this Policy Brief is: to assess the Social Investment Package against the normative framework developed on the human rights and capabilities approaches (HRCA) and to highlight the key policy implications for a renewed social investment agenda.

Towards more inclusive social protection and active labour market policies in the EU: a social investment perspective
Creators: name: Nicaise, I.
name: Lehwess-Litzmann, R.
Publisher: name: Zenodo
Year: 2019

description: Work Package 5 of the Re-InVEST project – synthesised in this policy brief – applies the notion of social investment to the policy areas of social protection and active labour market policies. Both policies are wide-ranging in themselves, but so intimately connected that it is hard to examine them separately.

The European Commission’s Annual Growth Survey for 20192 and the accompanying Joint Employment Report3 reflect a strong social investment perspective, with a lot of attention for education and training, childcare, health care, targeted active labour market measures and integrated services for vulnerable groups. Yet, the discourse in these documents concerning social protection remains rather ambiguous, with no emphasis on better coverage or more decent benefit levels except for the guaranteed minimum income.

This policy brief argues that better social protection is necessary and does not trap people into dependency. It also questions the quality of active labour market policies and calls for a European quality framework in this area.

description: We discuss the gamma-ray absorption in the inner region of the microquasar SS433. Our investigation includes several contributions to the opacity of this system. They result from the ambient fields generated by the primary star, possibly an A-type supergiant, and a very extended disk around the black hole. Besides the sharp and dramatic absorption effect that occurs every time the star crosses the emission zone, we find in the UV photon field from the extended disk an important source of absorption for very high energy gamma-rays. This results in periodic gamma-ray observational signatures.

Minimal standards

description: 1. Scope Recommendations for the responsible inclusion of special groups of data subjects in 1+MG such as minors, persons not able to consent, minorities, vulnerable persons and groups, and deceased persons. The recommendations are directed towards researchers, research ethics committees (RECs), and 1+MG data centres and oversight bodies. 2. Objectives − To identify existing approaches and best practices for inclusion of special groups. − To develop 1+MG minimal requirements for inclusion of special subjects. 3. Background The term ‘special subjects’ in the context of 1+MG project applies to a diverse set of potential research subjects: minors, persons with diminished capacity to consent, persons not able to consent, other vulnerable groups, deceased persons etc. These special subjects in at least some respects are incapable of deliberating or acting based on their own plans or are controlled by others. To respect a person representing special group means to protect him/her to ensure that the person is not subjected to abuse, exploitation, or discrimination. Usually, definitions of vulnerability combine two aspects: (1) lack of ability, capacity, means and/or willingness to protect one's own interests, and (2) exposure to the possibility of being harmed, especially through exploitation. As outlined in the Declaration of Helsinki, vulnerable groups and individuals “may have an increased likelihood of being wronged or of incurring additional harm” (WMA, 2013). In case of involving vulnerable persons and groups in research “specific protections should be provided for vulnerable subjects and vulnerable populations, based on the general principle of acting in their best interest” (ESHG, 2003). There is ongoing discussion in the field of research ethics regarding the usefulness of the concept of vulnerable groups. CIOMS Guidelines advise to “avoid considering members of entire classes of individuals as vulnerable” (CIOMS, 2016) and instead suggest looking at specific characteristics and situations that may render persons vulnerable, as this can “aid in identifying the special protections needed” (CIOMS, 2016). CIOMS Guidelines also remind that different characteristics and situations generating vulnerability may co-exist, making some individuals more vulnerable than others. Evaluating vulnerability of research subjects or groups before involving them in research is a duty of researchers and respective research ethics committees (RECs). For initial identification of vulnerability, a useful tool is Kipnis's taxonomy of vulnerability in research

AbstractLonafarnib (Zokinvy™) is an orally active farnesyltransferase inhibitor developed by Eiger BioPharmaceuticals under license from Merck & Co. for the treatment of hepatitis D virus (HDV) infections, and progeria and progeroid laminopathies. The drug was originally discovered by Merck & Co as an investigational drug in oncology. In progeria, lonafarnib inhibits farnesyltransferase to prevent farnesylation and subsequent accumulation of progerin and progerin-like proteins in the nucleus and cellular cytoskeleton. In November 2020, lonafarnib received its first approval in the USA to reduce the risk of mortality in Hutchinson-Gilford Progeria Syndrome (HGPS) and for the treatment of processing-deficient progeroid laminopathies (with either heterozygous LMNA mutation with progerin-like protein accumulation, or homozygous or compound heterozygous ZMPSTE24 mutations) in patients ≥ 12 months of age with a body surface area (BSA) of ≥ 0.39 m2. Lonafarnib is under regulatory review in the European Union. Clinical development for the treatment of HDV infections is underway in multiple countries. This article summarizes the milestones in the development of lonafarnib leading to this first approval.

description: This Re-InVEST Policy Brief explores our Participatory Action Human Rights and Capability Approach (PAHRCA) approach to research and knowledge construction which we implemented in 13 countries over the 2015-2018 period. We briefly outline key concepts underpinning the PAHCRA approach, discuss how it was operationalised, and then reflect on the degree to which co-construction of knowledge is a form of ‘enabling research’ that enhances the collective agency of vulnerable groups in their fight for a more equitable society. Our specific social co-construction of knowledge illuminated how policies and practices can produce distinct experiences from the perspective of the most vulnerable.
On the relation between the astrophysical neutrino fluxes and the cosmic ray fluxes

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Some generalizations of the relation between high-energy astrophysical neutrino and cosmic ray fluxes are obtained, taking into account present results on the cosmic ray spectrum and composition as well as a more realistic modeling of the Galactic and extragalactic cosmic ray components down to PeV energies. It is found that the level of neutrino fluxes measured by IceCube can be consistent with sources that are thin to escaping protons. This could also make it easier for heavier nuclei to be emitted from the sources without suffering excessive disintegration processes.

Detection of a 1258 Hz high-amplitude kilohertz quasi-periodic oscillation in the ultra-compact X-ray binary 1A 1246-588

description: We have observed the ultra-compact low-mass X-ray binary (LMXB) 1A 1246-588 with the Rossi X-ray Timing Explorer (RXTE). In this manuscript we report the discovery of a kilohertz quasi-periodic oscillation (QPO) in 1A 1246-588. The kilohertz QPO was only detected when the source was in a soft high-flux state reminiscent of the lower banana branch in atoll sources. Only one kilohertz QPO peak is detected at a relatively high frequency of 1258+-2 Hz and at a single trial significance of more than 7 sigma. Kilohertz QPOs with a higher frequency have only been found on two occasions in 4U 0614+09. Furthermore, the frequency is higher than that found for the lower kilohertz QPO in any source, strongly suggesting that the QPO is the upper of the kilohertz QPO pair often found in LMXBs. The full-width at half maximum is 25+-4 Hz, making the coherence the highest found for an upper kilohertz QPO. From a distance estimate of ~6 kpc from a radius expansion burst we derive that 1A 1246-588 is at a persistent flux of ~0.2-0.3 per cent of the Eddington flux, hence 1A 1246-588 is one of the weakest LMXBs for which a kilohertz QPO has been detected. The root-mean-square (rms) amplitude in the 5-60 keV band is 27+-3 per cent, this is the highest for any kilohertz QPO source so far, in line with the general anti-correlation between source luminosity and rms amplitude of the kilohertz QPO peak identified before. Using the X-ray spectral information we produce a colour-colour diagram. The source behaviour in this diagram provides further evidence for the atoll nature of the source.

description: All light has structure, but only recently it has become possible to construct highly controllable and precise potentials so that most laboratories can harness light for their specific applications. In this chapter, we review the emerging techniques for high-resolution and configurable optical trapping of ultracold atoms. We focus on optical deflectors and spatial light modulators in the Fourier and direct imaging configurations. These optical techniques have enabled significant progress in studies of superfluid dynamics, single-atom trapping, and underlie the emerging field of atomtronics. The chapter is intended as a complete guide to the experimentalist for understanding, selecting, and implementing the most appropriate optical trapping technology for a given application. After introducing the basic theory of optical trapping and image formation, we describe each of the above technologies in detail, providing a guide to the fundamental operation of optical deflectors, digital micromirror devices, and liquid crystal spatial light modulators. We also describe the capabilities of these technologies for manipulation of trapped ultracold atoms, where the potential is dynamically modified to enable experiments, and where time-averaged potentials can realise more complex traps. The key considerations when implementing time-averaged traps are described.

We propose the way of generalization of inflationary scenarios with the Gauss-Bonnet term and a scalar field minimally coupled with the Ricci scalar to the corresponding scenarios with a scalar field nonminimally coupled with the Ricci scalar. Using the effective potential, we construct a set of models with the same values of the scalar spectral index $n_s$ and the amplitude of the scalar perturbations $A_s$ and different values of the tensor-to-scalar ratio $r$.

description: We have developed an experimental device for studying the main mechanism of dust formation in electric arc furnace steelmaking: the burst of gas bubbles at the liquid steel surface. As in the case of the air-water system, the bubble-burst process takes place in three steps: breaking of the film cap, projection of film drops, and projection of jet drops. The film break and the jet drop formation are observed with a high-speed video camera. The film drop aerosol enters a particle counter, which characterizes the drops in size and number. Results are presented and discussed. The quantification of both types of projections leads to the conclusion that the film drop projections represent the major source of dust. The amount of film drops greatly decreases with the parent bubble size. Bubbles with diameter under 4mm theoretically do not produce film drops. Decreasing the CO-bubble size enough would therefore represent an effective solution for reducing drastically the electric arc furnace dust emission.
A case study of the acquisition of vocabulary by a group of ESL students examined from the perspective of knowledge structures
Creators: name: Henry, David Alexander
Publisher: name: University of British Columbia
Year: 2010

description: This case study examined the processes of vocabulary teaching and learning in a sixth grade ESL classroom. In examining the processes of vocabulary teaching and learning, the method used was a qualitative analysis of classroom discourse. The classroom followed a language teaching approach which was content based (or thematic) and was organized primarily around a framework of the knowledge structures of classification and description. The study focussed on classification and description and made a distinction between the language of classifying and describing a specific topic and the metalanguage of classification. In examining the processes of vocabulary teaching and learning the study made a distinction between direct strategies (such as giving definitions) and indirect strategies (which called for contextual use). Results suggested that: 1. indirect strategies of teaching language and vocabulary seemed to be more effective than direct strategies; 2. the teaching focus on classification and description was reflected in the use of the language of classification and description and the metalanguage of classification; 3. teachers used more of the language and metalanguage of classification than the students but not as wide a range as occurs in written discourse; 4. students seemed to acquire and use less of the metalanguage of classification than of the the language of classification and description, and preferred syntactic rather than lexical realizations when discussing classification and description; 5. when the language used corresponded to the knowledge structure of the topic, this appeared to help the learning of words associated with the topic; 6. assessing the quality of students' use of the terms associated with the knowledge structure of a topic seemed to be useful in evaluating their understanding of the topic.

description: We demonstrate existence of waves localized at the interface of two nonlinear periodic media with different coefficients of the cubic nonlinearity via the one-dimensional Gross--Pitaevsky equation. We call these waves the surface gap solitons (SGS). In the case of smooth symmetric periodic potentials, we study analytically bifurcations of SGS's from standard gap solitons and determine numerically the maximal jump of the nonlinearity coefficient allowing for the SGS existence. We show that the maximal jump vanishes near the thresholds of bifurcations of gap solitons. In the case of continuous potentials with a jump in the first derivative at the interface, we develop a homotopy method of continuation of SGS families from the solution obtained via gluing of parts of the standard gap solitons and study existence of SGS's in the photonic band gaps. We explain the termination of the SGS families in the interior points of the band gaps from the bifurcation of linear bound states in the continuous non-smooth potentials.

description: We probe type IIA geometries with \emph{folded} semiclassical strings those encode the strong coupling dynamics associated with long operators in a class of SCFTs pertaining to spacetimes whose dimension vary from $6d$ down to $2d$. We particularly focus on folded string configurations those are extended through stack of flavor $ Dp $ ($ p=6,8 $) branes localized along the internal manifold. Considering some specific examples within the realm of $ \mathcal{N}=2 $ linear quivers, we show that the associated string spectrum exhibits a pole as the string approaches flavor D6 branes. We identify this as a \emph{fragmentation} of long operators in the dual $ \mathcal{N}=2 $ SCFTs. On the other hand, a similar analysis for $ \mathcal{N}=(1,0) $ SCFTs in $6d$ as well as $ \mathcal{N}=(0,4) $ SCFTs in $ 4d $ reveals a set of new dispersion relations at strong coupling. Based on semiclassical calculations, we set an argument that explains either of these cases.

description: We investigate the statistics of three kinds of records associated with planar random walks, namely diagonal, simultaneous and radial records. The mean numbers of these records grow as universal power laws of time, with respective exponents 1/4, 1/3 and 1/2. The study of diagonal and simultaneous records relies on the underlying renewal structure of the successive hitting times and locations of translated copies of a fixed target. In this sense, this work represents a two-dimensional extension of the analysis made by Feller of ladder points, i.e., records for one-dimensional random walks. This approach yields a variety of analytical asymptotic results, including the full statistics of the numbers of diagonal and simultaneous records, the joint law of the epoch and location of the current diagonal record and the angular distribution of the current simultaneous record. The sequence of radial records cannot be constructed in terms of a renewal process. In spite of this, their mean number is shown to grow with a super-universal square-root law for isotropic random walks in any spatial dimension. Their full distribution is also obtained. Higher-dimensional diagonal and simultaneous records are also briefly discussed.

description: We present a catalogue of morphologically classified bright galaxies in the north equatorial stripe (230 deg$^2$) derived from the Third Data Release of the Sloan Digital Sky Survey (SDSS). Morphological classification is performed by visual inspection of images in the $g$ band. The catalogue contains 2253 galaxies complete to a magnitude limit of $r=16$ after Galactic extinction correction, selected from 2658 objects that are judged as extended in the photometric catalogue in the same magnitude limit. 1866 galaxies in our catalogue have spectroscopic information. A brief statistical analysis is presented for the frequency of morphological types and mean colours in the catalogue. A visual inspection of the images reveals that the rate of interacting galaxies in the local Universe is approximately 1.5% in the $r\le16$ sample. A verification is made for the photometric catalogue generated by the SDSS, especially as to its bright end completeness.

description: The rotation averaging problem is a fundamental task in computer vision applications. It is generally very difficult to solve due to the nonconvex rotation constraints. While a sufficient optimality condition is available in the literature, there is a lack of \yhedit{a} fast convergent algorithm to achieve stationary points. In this paper, by exploring the problem structure, we first propose a block coordinate descent (BCD)-based rotation averaging algorithm with guaranteed convergence to stationary points. Afterwards, we further propose an alternative rotation averaging algorithm by applying successive upper-bound minimization (SUM) method. The SUM-based rotation averaging algorithm can be implemented in parallel and thus is more suitable for addressing large-scale rotation averaging problems. Numerical examples verify that the proposed rotation averaging algorithms have superior convergence performance as compared to the state-of-the-art algorithm. Moreover, by checking the sufficient optimality condition, we find from extensive numerical experiments that the proposed two algorithms can achieve globally optimal solutions.

description: We present the preliminary results from two new surveys of blazars that have direct implications on the GLAST detection of extragalactic sources from two different perspectives: microwave selection and a combined deep X-ray/radio selection. The first one is a 41 GHz flux-limited sample extracted from the WMAP 3-yr catalog of microwave point sources. This is a statistically well defined sample of about 200 blazars and radio galaxies, most of which are expected to be detected by GLAST. The second one is a new deep survey of Blazars selected among the radio sources that are spatially coincident with serendipitous sources detected in deep X-ray images (0.3-10 keV) centered on the Gamma Ray Bursts (GRB) discovered by the Swift satellite. This sample is particularly interesting from a statistical viewpoint since a) it is unbiased as GRBs explode at random positions in the sky, b) it is very deep in the X-ray band (\fx \simgt $10^{-15}$ \ergs) with a position accuracy of a few arc-seconds, c) it will cover a fairly large (20-30 square deg.) area of sky, d) it includes all blazars with radio flux (1.4 GHz) larger than 10 mJy, making it approximately two orders of magnitude deeper than the WMAP sample and about one order of magnitude deeper than the deepest existing complete samples of radio selected blazars, and e) it can be used to estimate the amount of unresolved GLAST high latitude gamma-ray background and its anisotropy spectrum.

New insights on the dense molecular gas in NGC253 as traced by HCN and HCO+

description: We have imaged the central ~1kpc of the circumnuclear starburst disk in the galaxy NGC253 in the HCN(1-0), HCO+(1-0), and CO(1-0) transitions at 60pc resolution using the Owens Valley Radio Observatory Millimeter-Wavelength Array (OVRO). We have also obtained Atacama Pathfinder Experiment (APEX) observations of the HCN(4-3) and the HCO+(4-3) lines of the starburst disk. We find that the emission from the HCN(1-0) and HCO+(1-0) transitions, both indicators of dense molecular gas, trace regions which are non-distinguishable within the uncertainties of our observations. Even though the continuum flux varies by more than a factor 10 across the starburst disk, the HCN/HCO+ ratio is constant throughout the disk, and we derive an average ratio of 1.1+/-0.2. From an excitation analysis we find that all lines from both molecules are subthermally excited and that they are optically thick. This subthermal excitation implies that the observed HCN/HCO+ line ratio is sensitive to the underlying chemistry. The constant line ratio thus implies that there are no strong abundance gradients across the starburst disk of NGC253. This finding may also explain the variations in L'(HCN)/L'(HCO+) between different star forming galaxies both nearby and at high redshifts.

description: Hawking radiation is nowadays being understood as tunnelling through black hole horizons. Here, the extension of the Hamilton-Jacobi approach to tunnelling for non-rotating and rotating black holes in different non-singular coordinate systems not only confirms this quantum emission from black holes but also reveals the new phenomenon of absorption into white holes by quantum mechanical tunnelling. The role of a boundary condition of total absorption or emission is also clarified.

description: The production of $η^{(\prime)}π$ pairs constitutes one of the golden channels to search for hybrid exotics, with explicit gluonic degrees of freedom. Understanding the dynamics and backgrounds associated to $η^{(\prime)}π$ production above the resonance region is required to impose additional constraints to the resonance extraction. We consider the reaction $π^-p\to η^{(\prime)} π^- \,p$ measured by COMPASS. We show that the data in $2.4 < m_{η^{(\prime)}π} < 3.0$ GeV can be described by amplitudes based on double-Regge exchanges. The angular distribution of the meson pairs, in particular in the $η' π$ channel, can be attributed to flavor singlet exchanges, suggesting the presence of a large gluon content that couples strongly to the produced mesons.

The relationship between teachers' attitudes to the teaching of writing and whole-language/skills-based philosophies
Creators: name: Marshall, Ailsa
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated teachers' attitudes towards four specific strands isolated from views propounded in recent literature and research on the teaching of written composition. Much discussion in this field has focused on a "new paradigm" in that educators and researchers alike have come to view writing from a new perspective. Certain aspects of this new perspective on the teaching of writing appear to be shared by various sources in the literature. From this body of writing the researcher identified and isolated four distinct, though interwoven, shared values or "strands." These concerned Control on the part of the student-writer, Respect for what the student-writer has to say in his or her writing, Sharing the writing process, and Learning from writing by using writing as a tool for learning. A questionnaire was constructed to probe teachers' attitudes to each of these strands. Two sample populations, one with a whole-language and one with a non-integrated orientation towards teaching language, were identified. Twenty-five teachers from each population answered a three-part questionnaire. The main body of the survey probed attitudes to each of the strands. T-test results indicate that, while the whole-language oriented group reacted more favorably to all four strands in general, statistically this was highly significant in only two of the strands. That is, CONTROL on the part of the writer, and SHARING the writing process as in a community of writers appeared to be valued more highly amongst teachers with a whole-language orientation. This suggests that there may be a relationship between a whole-language orientation and these two aspects of teaching writing.
