description: We present a lensing and photometric study of the exceptional system SDSS J1538+5817, identified by the SLACS survey. The lens is a luminous elliptical at redshift z=0.143. Using HST public images in two different filters, the presence of two background sources lensed into an Einstein ring and a double system is ascertained. Our new spectroscopic observations, performed at the NOT, reveal that the two sources are located at the same redshift z=0.531. We investigate the total mass distribution of the lens between 1 and 4 kpc from the galaxy center by means of parametric and non-parametric lensing codes that describe the multiple images as point-like objects. Several disparate lensing models agree on: (1) reproducing accurately the observed image positions; (2) predicting a nearly axisymmetric total mass distribution, centered and oriented as the light distribution; (3) measuring a value of 8.11 x 10^{10} M_{Sun} for the total mass projected within the Einstein radius of 2.5 kpc; (4) estimating a total mass density profile slightly steeper than an isothermal one. A fit of the SDSS multicolor photometry with CSP models provides a value of 20 x 10^{10} M_{Sun} for the total stellar mass of the galaxy and of 0.9 for the fraction of projected luminous over total mass enclosed inside the Einstein radius. By combining lensing and photometric mass measurements, we differentiate the lens mass content in terms of luminous and dark matter components. This two-component modeling, which is viable only in extraordinary systems like SDSS J1538+5817, leads to a description of the global properties of the galaxy dark matter halo. Extending these results to a larger number of lenses would improve considerably our understanding of galaxy formation and evolution processes in the LCDM scenario.

Projecting catch potential for British Columbia First Nations under climate change and fisheries management scenarios

description: Human activities, particularly climate change and over-exploitation, negatively impact marine biodiversity and seafood availability which is a source of food for many coastal communities to be negatively impacted. Coastal First Nations in British Columbia are inherently connected to marine life through fishing - thus, it's crucial to explore climate change and fisheries' effects on fish stocks. This study assessed the potential seafood availability from 24 marine species that are important for four First Nations in British Columbia: Skidegate, ‘Namgis, Tla’amin, and Nuxalk (Bella Coola). This study estimated that in 2018, the marine food harvest for the communities totaled approximately 28.3, 27.0, 27.9, and 19.0 tonnes, respectively. Using a Dynamic Bioclimate Envelope model, the study projected potential changes in seafood availability, for the four First Nations under climate change and fishing scenarios. Sockeye salmon (Oncorhynchus nerka), chinook salmon (Oncorhynchus tshawytscha), and eulachon (Thaleichthys pacificus) were most sensitive to climate change, with projected declines by 2090 under the high emissions scenarios, while pink salmon (Oncorhynchus gorbuscha), Nuttall’s cockle (Clainocardium nuttallii), and dolly varden trout (Salvelinus malma malma) were more resilient to climate change. Tla’amin faced the greatest risk of climate change on potential seafood availability, with an average of 15.8% decline under the higher emissions scenario while Skidegate was projected to be the least affected. The effect of fishing scenarios on seafood availability was shown to play a significant role in seafood availability. Under a 'conservation-focused' scenario i.e., fishing level in British Columbia waters is managed at half of the level at maximum sustainable yield (MSY), the model projected 58.5% higher seafood availability to the four coastal First Nations by 2090 relative to 2018, compared to managing at MSY. In contrast, fishing level at iv 50% above MSY led to a 55.5% decrease in seafood availability. The study underscores the intricate relationship between climate change, fisheries management, and seafood availability for coastal First Nations in British Columbia. The research suggests a context-based strategy, incorporating First Nations' needs, as necessary foundation for effective climate adaptation and fisheries management.

description: Within the last decade, discourse analysts have delved into the private sphere to examine the institution of the family. Analysts have noted how the family is a fertile research site and how investigation of family interaction gives, among other things, crucial insight into the intricate relational struggles between parents and their children. Considered a micro institution, the family provides the day-to-day context in which relations of power and connection are enacted, and human bonds are either severed or forged. In this respect, it is a key social institution, one “that mediates the individual and the social, with identifiable structures, functions, and hierarchies” (Sarangi, 2006, p. 403).

description: In the last few years we have witnessed the emergence, primarily in on-line communities, of new types of social networks that require for their representation more complex graph structures than have been employed in the past. One example is the folksonomy, a tripartite structure of users, resources, and tags -- labels collaboratively applied by the users to the resources in order to impart meaningful structure on an otherwise undifferentiated database. Here we propose a mathematical model of such tripartite structures which represents them as random hypergraphs. We show that it is possible to calculate many properties of this model exactly in the limit of large network size and we compare the results against observations of a real folksonomy, that of the on-line photography web site Flickr. We show that in some cases the model matches the properties of the observed network well, while in others there are significant differences, which we find to be attributable to the practice of multiple tagging, i.e., the application by a single user of many tags to one resource, or one tag to many resources.

description: This brief essay focuses on a single turn in an interchange between an adult educator (Anna), and a five-year old girl (Claire), who are playing math games together. Using multiple layers of contextual information, the paper shows how much interactional work can be involved in teacher talk, even in an informal setting. First, conversation analysis (CA) is used to analyze the turn in question, as well as its sequential context. Next, data from a participant interview is described within the context of Goffman‟s (1974) theories of frames and footing. Thus, four layers of context—turn, sequence, participant interview, and frames—work together to help describe this pedagogical interaction.

description: We present radiative transfer models for submillimeter galaxies with spectroscopic redshifts and mid-infrared spectroscopy from Spitzer/IRS and analyze available Spitzer/MIPS 24, 70 and 160mu data. We use two types of starburst models, a cirrus model and a model for the emission of an AGN torus in order to investigate the nature of these objects. We find that for three of the objects (25%) cirrus emission alone can account for the mid-infrared spectrum and the MIPS and submillimeter data. For the remaining objects we find that we need a combination of starburst and cirrus in order to fit simultaneously the multi--wavelength data. We find that the typical submillimeter galaxy has comparable luminosity in the starburst (median L=10^12.5 Lo) and cirrus (median L=10^12.4 Lo) components. This could arise if the galaxies have been forming stars continuously for the last 250Myr with the star formation occurring in the last 5Myr being shrouded by high-optical-depth molecular cloud dust, whereas the rest of the starlight is attenuated by diffuse dust or cirrus with an Av of about 1mag.

Classroom as Context: Procedural Consequentiality in a Secondary English Classroom

Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2010

description: Discussions abound concerning the role of context when examining data from a conversation analytic (CA) framework. Lively debates concerning the place of gender, class, and other cultural constructs in CA (e.g. Schegloff, 1997; Wetherall, 1998) have led some to conclude that nothing other than the talk itself can be used when practicing CA. However, Schegloff (1991, 1992) has noted at least two instances when the relevance of contextual features can be shown. One of those notions, termed procedural consequentiality (Schegloff, 1992), denotes that a certain aspect of context affects how the interaction unfolds. This brief discussion will analyze such a spate of talk, where the very direction of the conversation is contingent on the fact that a teacher is interacting with students.

description: We use a deep Chandra observation to examine the structure of the hot intra-group medium of the compact group of galaxies Stephan's Quintet. The group is thought to be undergoing a strong dynamical interaction as an interloper, NGC 7318b, passes through the group core at ~850 km/s. A bright ridge of X-ray and radio continuum emission has been interpreted as the result of shock heating, with support from observations at other wavelengths. We find that gas in this ridge has a similar temperature (~0.6 keV) and abundance (~0.3 solar) to the surrounding diffuse emission, and that a hard emission component is consistent with that expected from high-mass X-ray binaries associated with star-formation in the ridge. The cooling rate of gas in the ridge is consistent with the current star formation rate, suggesting that radiative cooling is driving the observed star formation. The lack of a high-temperature gas component is used to place constraints on the nature of the interaction and shock, and we find that an oblique shock heating a pre-existing filament of HI may be the most likely explanation of the X-ray gas in the ridge. The mass of hot gas in the ridge is only ~2 per cent of the total mass of hot gas in the group, which is roughly equal to the deficit in observed HI mass compared to predictions. The hot gas component is too extended to have been heated by the current interaction, strongly suggesting that it must have been heated during previous dynamical encounters.

Liquid embolization of brain arteriovenous malformation using novel detachable tip micro catheter: a technical report
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background and importance—Liquid embolization using Onyx® of brain arteriovenous malformations (AVMs) is sometimes limited by micro catheter retention by Onyx® cast during the disengagement process. Use of the new detachable tip micro catheter is presented in this report. Clinical presentation—Two feeding arteries of a previously ruptured brain AVM in a 62-year-old man were embolized by Onyx 18 prior to surgery using the new Apollo™ micro catheter with the detachable-tip (30 mm) was utilized. The arterial feeders were accessed without difficulty by micro catheter, guided by 0.010" microwire. Onyx reflux around the distal end of the micro catheter was necessary for effective embolization of arteriovenous fistulous components of brain AVM. The micro catheter was successfully retracted after embolization in both feeding arteries, with distal end detachment seen in one but not the other arterial embolization. No arterial thrombosis, vasospasm, dissection, or rupture was seen at respective sites of disengagement. Conclusion—Use of the new micro catheters with detachable-tip design allowed prolonged Onyx® injection times, safe micro catheter disengagement, without any limitations in accessing target arterial feeders.
Teacher Knowledge as Context

description: Research has shown that teachers bring into the classroom multiple domains of knowledge, including disciplinary knowledge, pedagogical content knowledge (i.e., the process of relaying disciplinary knowledge to students), knowledge of how learning occurs, knowledge of students’ learning styles, knowledge of curricular and contextual demands, their own personal practical knowledge (e.g., experiences in the classroom as a student; cultural norms surrounding the role of a teacher), and knowledge of how to reflect on all of these domains in order to adapt one’s teaching accordingly1. This piece will briefly explain and demonstrate the importance in examining teacher knowledge as context within classroom discourse analysis in order to enrich the understanding of what is happening in classroom interaction and explain why it is so.

Culture as Context
Creators: name: Takahashi, Junko
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2010

description: The relationship between context and culture seems to result in certain patterns, forms, and linguistic or non-linguistic features. They are all packaged in a product called “text.” If we closely observe our own linguistic behavior, we can see how much all of these elements affect each other. From a discourse analytic perspective, culture is a necessary aspect to examine in order to infer what is truly occurring in a conversation. Gumperz (1982) suggests that no matter what the context is, “all verbal behavior is governed by social norms specifying participant roles, rights and duties vis-à-vis each other” (p.165). He warns us of the danger of misunderstanding the speaker’s intentions and meanings if we solely rely on our own cultural background to interpret the talk. For instance, Hill, Ide, Ikuta, Kawasaki and Ogino (1986) and Ide (2006) assert that a strict Japanese social code for politeness called “wakimae” (discernment) requires all Japanese speakers to comply with it without choice in their verbal activities. Japanese society emphasizes humility and one way this is realized is the use of the “non-acceptance” strategy in compliment responses.

description: Understanding NP-complete problems is a central topic in computer science. This is why adiabatic quantum optimization has attracted so much attention, as it provided a new approach to tackle NP-complete problems using a quantum computer. The efficiency of this approach is limited by small spectral gaps between the ground and excited states of the quantum computer's Hamiltonian. We show that the statistics of the gaps can be analyzed in a novel way, borrowed from the study of quantum disordered systems in statistical mechanics. It turns out that due to a phenomenon similar to Anderson localization, exponentially small gaps appear close to the end of the adiabatic algorithm for large random instances of NP-complete problems. This implies that unfortunately, adiabatic quantum optimization fails: the system gets trapped in one of the numerous local minima.

Another Look at Norris and Ortega (2000)

Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2010

description: Since Norris and Ortega‟s (2000) seminal work on the effectiveness of second language instruction, there has been a proliferation of meta-analyses in the field of applied linguistics. Subsequent meta-analysts, however, have uncritically followed the methodological choices made by Norris and Ortega. This paper suggests a critical reevaluation of the methodological procedures underlying the Norris and Ortega (2000) meta-analysis. I reexamined their procedures, and reassessed the 49 unique samples they used in their meta-analysis. In doing so, I identified three key methodological limitations with the study, pertaining, respectively, to (a) the data collection procedure, (b) the coding system, and (c) the statistical analysis. I argue that the lack of data quality inherent in the primary studies, the oversimplified coding scheme, and the inappropriate use of effect size statistics combine to compromise the validity of the conclusions Norris and Ortega have drawn from their meta-analysis. I subsequently provide alternative procedures which may yield a more empirically sound research synthesis, recommending, for future meta-analysts, the „best evidence synthesis‟ approach where conclusions are drawn from combining quantitative and qualitative analyses.

Speech Characteristics of Japanese Speakers Affecting American and Japanese Listener Evaluations

Year: 2010

description: The study examines what pronunciation features (i.e., segmental and suprasegmental features, as well as other acoustic properties such as speech rate, intensity, pitch, and pitch range) affect the intelligibility of Japanese learners of English, when judged by native-speaking (NS; American) and non-native-speaking (NNS; Japanese) listeners. Kashiwagi and Snyder (2008) concluded, based on both statistical and interview data, that intelligibility and accentedness judgments were quasi-independent of each other, and that segmental features in the speech samples of Japanese learners were perceived both by NS (American) and NNS (Japanese) listeners to be more problematic than suprasegmentals. The present study is designed to verify these conclusions by re-examining the data with further statistical procedures. Additional data on speech rate, intensity, pitch, and pitch range were also added to the statistical analyses to explore the issue of intelligibility. The resulting data suggest that non-native pronunciation of segmentals, especially of certain vowels, affect the judgments of intelligibility most strongly, and that intelligibility scores and accentedness ratings are controlled by different sets of factors. Speech rate, intensity, pitch and pitch range are also found to have some effects. The data also suggest that NS (American) and NNS (Japanese) listeners are affected differently by certain pronunciation features.

The interaction relies on surface forces experienced by the atoms at about one micrometer distance from the mechanical structure. We observe resonant coupling to several well-resolved mechanical modes of the condensate. Coupling via surface forces does not require magnets, electrodes, or mirrors on the oscillator and could thus be employed to couple atoms to molecular-scale oscillators such as carbon nanotubes.

Frames, Footing, and Teacher-Initiated Questions: An Analysis of a Beginning French Class for Adults
Creators: name: Creider, Sarah
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2009

description: Unlike children learning to speak, adults come to the language-learning process with years of life experience. They may be beginners in a new language, but they are not beginners in their own lives. Yet, some of the most common types of teacher/student exchanges, especially those that follow a teacher-initiated question, may lead to situations in which students who are speaking about familiar topics still feel, act, and are treated as novices. This paper explores a beginning French class for adults, asking how the class participants deal with dual — and sometimes conflicting — roles. On the one hand, the teacher‘s knowledge of French puts her in the role of expert, especially in comparison to her beginning-level students. At the same time, teacher and students are all adults who, outside of the classroom, would meet as equals in terms of general knowledge and experience. These shifting roles can be seen especially clearly in interchanges following questions about students‘ own lives. While it seems evident that a student would know more about her background than anyone else, such questions often seem more like tests of how well students can answer in French than actual requests for information.

description: We report on the numerical discovery of quasi-periodic oscillations (QPOs) associated with accretion through a non-axisymmetric magnetic boundary layer in the unstable regime, when two ordered equatorial streams form and rotate synchronously at approximately the angular velocity of the inner disk The streams hit the star's surface producing hot spots. Rotation of the spots leads to high-frequency QPOs. We performed a number of simulation runs for different magnetospheric sizes from small to tiny, and observed a definite correlation between the inner disk radius and the QPO frequency: the frequency is higher when the magnetosphere is smaller. In the stable regime a small magnetosphere forms and accretion through the usual funnel streams is observed, and the frequency of the star is expected to dominate the lightcurve. We performed exploratory investigations of the case in which the magnetosphere becomes negligibly small and the disk interacts with the star through an equatorial belt. We also performed investigation of somewhat larger magnetospheres where one or two ordered tongues may dominate over other chaotic tongues. In application to millisecond pulsars we obtain QPO frequencies in the range of 350 Hz to 990 Hz for one spot. The frequency associated with rotation of one spot may dominate if spots are not identical or antipodal. If the spots are similar and antipodal then the frequencies are twice as high. We show that variation of the accretion rate leads to drift of the QPO peak.

Positions : possibilities and pleasures in gay, bisexual, and queer men's storytelling
Creators: name: Gendron, Mathew
Publisher: name: University of British Columbia

description: Sex between gay, bisexual, and queer (GBQ) men has been primarily explored through sexual health and public health frameworks (Adam, 2016; Frost, 2017; Salway Hottes et al., 2015). Despite producing valuable research on GBQ men’s sexual decision-making and health disparities, these frameworks have struggled to capture the complex idiosyncrasies of GBQ men’s sex. Hermeneutically-informed theories of human agency call for research that holds biophysical and sociocultural aspects of human experience in their complexity (Martin et al., 2003), while positioning theories further explore how one’s situatedness in available storylines shapes what can be experienced at a given time and place (Harré, 2012, 2015; Harré & van Langenhove, 1991). Aligned with counselling psychology’s aspirations toward sex-positivity (Burnes et al., 2017), I leveraged these frameworks to develop situated understandings of GBQ men’s sex and pleasure. Twenty diverse GBQ men participated in a collaborative storytelling process adapted from Arvay’s (2003) collaborative narrative method. Participants told stories about pleasurable and unpleasurable sex they have had with men, which participants and I subsequently reviewed through collaborative reflection. Thematic analysis (Braun et al., 2019; Braun & Clarke, 2006, 2019) of these reflections produced four themes and 11 subthemes that explore how GBQ men narrate themselves in sexual stories and how GBQ men’s narrative positions shape perceived possibilities and pleasures in sex. I discuss the importance of understanding GBQ men’s sex in its layered complexity before discussing implications for future sex-positive research and counselling practice.
Acculturation, Interpersonal Networks, and the Learner’s Sense of Self: The Effects of Social Relationships on Second Language Learning

description: In reaction to what they considered the prevailing bias of second language acquisition (SLA) research towards cognitive-oriented theories, Firth and Wagner (1997) called for a greater recognition of the social context and interactive nature of language use. Without negating the importance of cognitive dimensions of learning, the authors noted that ―language is acquired and learned through social interaction … and should be studied in interactive encounters‖ (Firth & Wagner, 1997, p. 287). The article set off a firestorm of controversy. Some critics argued that language acquisition is ―fundamentally a psycholinguistic process‖ (Gass & Selinker, 2001, p. 239), and that language acquisition and language use are two entirely separate entities (Gass 1998). Firth and Wagner acknowledged this criticism, but still maintained that language acquisition ―is built on language use‖ (Firth & Wagner, 2007, p. 806) and that it is a process that takes place ―in the micromoments of social interaction‖ (Firth & Wagner, 2007, p. 807). This perspective was echoed by Wenger (1998), who stated that ―learners are social beings … this fact is a central aspect of learning‖ (Wenger, 1998, p. 4).

description: Using measured spin-transfer rates from alkali atoms to He-3, combined with spin-relaxation rates of the alkali atoms due to He-3 and He-4, it should be possible to differentiate between isotropic and anisotropic spin-exchange. This would give a fundamental limit on the He-3 polarization attainable in spin-exchange optical pumping. For K-He, we find the limit to be 0.90+-0.11.

description: We present a rigorous analysis of the Landau-Zener linear-in-time term crossing problem for quadratic-nonlinear systems relevant to the coherent association of ultracold atoms in degenerate quantum gases. Our treatment is based on an exact third-order nonlinear differential equation for the molecular state probability. Applying a variational two-term ansatz, we construct a simple approximation that accurately describes the whole-time dynamics of coupled atom-molecular system for any set of involved parameters. Ensuring an absolute error less than for the final transition probability, the resultant solution improves by several orders of magnitude the accuracy of the previous approximations by A. Ishkhanyan et al. developed separately for the weak coupling [J. Phys. A 38, 3505 (2005)] and strong interaction [J. Phys. A 39, 14887 (2006)] limits. In addition, the constructed approximation covers the whole moderate-coupling regime, providing for this intermediate regime the same accuracy as for the two mentioned limits. The obtained results reveal the remarkable observation that for the strong-coupling limit the resonance crossing is mostly governed by the nonlinearity, while the coherent atom-molecular oscillations arising soon after the resonance has been crossed are basically of linear nature. This observation is supposed to be of a general character due to the basic attributes of the resonance crossing processes in the nonlinear quantum systems of the discussed type of involved quadratic nonlinearity.

description: The aim of our study was to explore the relationship between the methylation status of the alpha-1A adrenergic receptor (ADRA1A) gene and hepatocellular carcinoma (HCC). We combined our in-house data-set with the Cancer Genome Atlas (TCGA) data-set to screen and identify the methylation status and expression of adrenergic receptor (AR) genes in HCC. Immunohistochemistry and western blot were performed to assess the expression of ADRA1A in HCC cell lines and tissues. We further evaluated the methylation levels of the ADRA1A promoter region in 160 HCC patients using the Sequenom MassARRAY® platform and investigated the association between methylation of ADRA1A and clinical characteristics. The expression levels of ADRA1A mRNA and protein were significantly decreased in HCC tissues. Compared with that in paired normal tissues, the mean methylation level of the ADRA1A promoter region was significantly increased in tumour tissues from 160 HCC patients (25.2% vs. 17.0%, P < 0.0001). We found that a DNA methyltransferase inhibitor (decitabine) could increase the expression of ADRA1A mRNA in HCC cell lines. Moreover, hypermethylation of the ADRA1A gene in HCC samples was associated with clinical characteristics, including alcohol intake (P = 0.0097) and alpha-fetoprotein (P = 0.0411). Receiver operator characteristic (ROC) curve analysis demonstrated that the mean methylation levels of ADRA1A could discriminate between HCC tissues and adjacent non-cancerous tissues (AUC = 0.700, P < 0.0001). mRNA sequencing indicated that the main enriched pathways were pathways in cancer, cytokine-cytokine receptor interaction and metabolic pathways (P < 0.01). ADRA1A gene hypermethylation might contribute to HCC initiation and is a promising biomarker for the diagnosis of HCC.

description: Using the functional integral method, we construct a theory of heterotic SIS Josephson junctions between single- and two-gap superconductors. The theory predicts the presence of in-phase and out-of-phase collective oscillation modes of superconducting phases. The former corresponds to the Josephson plasma mode whose frequency is drastically reduced for $\pm$ s-wave symmetry, and the latter is a counterpart of Leggett's mode in Josephson junctions. We also reveal that the critical current and the Fraunhofer pattern strongly depend on the symmetry type of the two-gap superconductor.

Hot and cool water in Herbig Ae protoplanetary disks. A challenge for Herschel

description: The spatial origin and detectability of rotational H2O emission lines from Herbig Ae type protoplanetary disks beyond 70 micron is discussed. We use the recently developed disk code ProDiMo to calculate the thermo-chemical structure of a Herbig Ae type disk and apply the non-LTE line radiative transfer code Ratran to predict water line profiles and intensity maps. The model shows three spatially distinct regions in the disk where water concentrations are high, related to different chemical pathways to form the water: (1) a big water reservoir in the deep midplane behind the inner rim, (2) a belt of cold water around the distant icy midplane beyond the snow-line r>20AU, and (3) a layer of irradiated hot water at high altitudes z/r=0.1...0.3, extending from about 1AU to 30AU, where the kinetic gas temperature ranges from 200K to 1500K. Although region 3 contains only little amounts of water vapour (~3x10^-5 M_Earth), we find this warm layer to be almost entirely responsible for the rotational water emission lines, execpt for the 3 lowest excitation lines. Thus, Herschel will probe first and foremost the conditions and radial extension of region 3, where water is predominantly formed via neutral-neutral reactions and the gas is thermally decoupled from the dust T_gas>T_dust. The observations do not allow for a determination of the snow-line, because the snow-line truncates the radial extension of region 1, whereas the lines originate from region 3. Different line transfer approximations (LTE, escape probability, Monte Carlo) are discussed. A non-LTE treatment is required in most cases, and the results obtained with the escape probability method are found to underestimate the Monte Carlo results by 2%...45%.

description: In this contribution we announce a complete classification and new exotic phenomena of the meromorphic structure of $\z$-functions associated to conic manifolds proved in \cite{KLP1}. In particular, we show that the meromorphic extensions of these $\z$-functions have, in general, countably many logarithmic branch cuts on the nonpositive real axis and unusual locations of poles with arbitrarily large multiplicity. Moreover, we give a precise algebraic-combinatorial formula to compute the coefficients of the leading order terms of the singularities.

Complex Systems and Applied Linguistics

description: With this monograph, Diane Larsen-Freeman and Lynne Cameron unveil a complex systems approach to applied linguistics in the first book-length introduction to the topic. Stirrings of a shift in this direction have begun to appear in Larsen-Freeman’s publications this past decade (e.g., 1997, 2002). Expanding on those early papers, this work is intended “to open the conversation” (Larsen-Freeman & Cameron, 2008, p. 255) about complex systems among applied linguists; however, it is not intended to be the last word. As such, it is a rich introduction for teachers, researchers, and students who want to foreground a dynamic worldview in their theory and method for understanding complex systems. This book begins a new chapter in the intellectual history of applied linguistics by repositioning our understandings and making change central. At the very least, the development of a complex systems approach to applied linguistics at the hands of two well-respected applied linguists, each with distinguished publications records, is cause enough to engage with its ideas.

description: By considering a nonlinear combination of the probabilities of a system, a physical interpretation of Tsallis statistics as representing the nonlinear coupling or decoupling of statistical states is proposed. The escort probability is interpreted as the coupled probability, with Q = 1 - q defined as the degree of nonlinear coupling between the statistical states. Positive values of Q have coupled statistical states, a larger entropy metric, and a maximum coupled-entropy distribution of compact-support coupled-Gaussians. Negative values of Q have decoupled statistical states and for -2 < Q < 0 a maximum coupled-entropy distribution of heavy-tail coupled-Gaussians. The conjugate transformation between the heavy-tail and compact-support domains is shown to be -2Q/(2+Q) for coupled-Gaussian distributions. This conjugate relationship has been used to extend the generalized Fourier transform to the compact-support domain and to define a scale-invariant correlation structure with heavy-tail limit distribution. In the present paper, we show that the conjugate is a mapping between the source of nonlinearity in non-stationary stochastic processes and the nonlinear coupling which defines the coupled-Gaussian limit distribution. The effects of additive and multiplicative noise are shown to be separable into the coupled-variance and the coupling parameter Q, providing further evidence of the importance of the generalized moments.
