Discours sur la peur et contre l’Europe dans les tracts du Front National (2008-2017)
Creators: name: Silletti, Alida Maria
Publisher: name: University of Turin
Year: 2019
Subjects: Marine Le Pen ; dédiabolisation ; tracts ; Union Européenne ; identité nationale

description: Le Front National pose comme raison d’être du mouvement la sécurité, la prospérité et l’identité nationales, la sauvegarde des valeurs traditionnelles, prônant un discours sur la peur vis-à-vis de ce qui porte atteinte à la France et à son peuple. Parmi ces menaces, au-delà de l’immigré, bouc émissaire traditionnel du mouvement, figurent également la mondialisation et l’UE. Cette contribution porte sur l’analyse de treize tracts du FN et de Marine Le Pen, disponibles sur le site du mouvement, parus entre 2008 et 2017, caractérisés par le renvoi à l’Union européenne en tant que responsable politique et économique de la situation de crise traversée par la France. Elle vise à identifier le discours sur la peur et contre l’Europe proposé par le FN à partir d’un examen des aspects visuels et du contenu des tracts en termes de stratégies référentielles et de structures argumentatives par le biais, entre autres, du vocabulaire et des illustrations choisis par leurs rédacteurs. Le cadre théorique sur lequel nous nous appuyons relève de la parole politique, du discours propagandiste et de la propagande politique réalisée via les tracts. Nous essaierons de montrer le parcours qui, partant de l’instigation de la peur, en passant par la désillusion du présent, aboutit à Marine Le Pen, « patriote » qui peut redresser la France, la guérir de ses maux et de sa dépendance vis-à-vis de l’UE, pour redonner la parole aux citoyens français. Ce travail nous permet ainsi de rappeler les caractéristiques qui font du FN un mouvement populaire, nationaliste, traditionnaliste, antimoderne, et ce malgré les tentatives de « dédiabolisation » que Marine Le Pen opère depuis 2003 du point de vue formel mais non pas des contenus abordés, qui restent ceux du FN.

description: We have computed radiative equilibrium models for the gas in the circumstellar envelope surrounding the hot, classical Be star $γ$Cassiopeia. This calculation is performed using a code that incorporates a number of improvements over previous treatments of the disk's thermal structure by \citet{mil98} and \citet{jon04}; most importantly, heating and cooling rates are computed with atomic models for H, He, CNO, Mg, Si, Ca, & Fe and their relevant ions. Thus, for the first time, the thermal structure of a Be disk is computed for a gas with a solar chemical composition as opposed to assuming a pure hydrogen envelope. We compare the predicted average disk temperature, the total energy loss in H$α$, and the near-IR excess with observations and find that all can be accounted for by a disk that is in vertical hydrostatic equilibrium with a density in the equatorial plane of $ρ(R)\approx 3$ to $5\cdot 10^{-11} (R/R_*)^{-2.5} \rm g cm^{-3}$. We also discuss the changes in the disk's thermal structure that result from the additional heating and cooling processes available to a gas with a solar chemical composition over those available to a pure hydrogen plasma.

description:
This theoretical paper is a Black feminist love letter to Toni Morrison from three cultural theorists and critical (teacher) educators constellating in a multiracialized doctoral student-professor assemblage. Following the claim that Morrison’s work is central to Critical Whiteness Studies (CWS), we articulate our unease with the ongoing epistemic anti-Black violence evidenced in CWS scholarship in teacher education. We wonder, what is the work of CWS in teacher education? Must we continue this work? Must we continue this work? Who are we and what has whiteness (work) done to us? Through a Morrisonian reading with the critical interventions suggested in Playing in the Dark, we closely read CWS in teacher education literature whilst employing letter writing, an exegetical cultural studies method, to explore the above questions. We further call for the death of whiteness while delighting in what Morrison’s theorizing vis-à-vis possibilities that lay in the beyond and after.

Coping skills of incest and sexual abuse victims
Creators: name: Phillips, Cecilie Anne Bannatyne
Publisher: name: University of British Columbia
Year: 2010

description: Childhood incest and sexual abuse was explored in depth to determine the coping skills used by victims, based upon their descriptive recall of these events. Eighteen adult women, who were group therapy members and leaders, were interviewed about their experiences as sexually abused children and adolescents. The critical incident technique was used to identify what hindered or facilitated the victims coping in the eighty-one abuse experiences collected. Each incident was categorized according to the identifiable stress, and the type of coping method used. Three categories of identifiable stress emerged from the data which were labelled offenders, significant others, and victims. Of these, the largest number of incidents related to stress created by offenders. In this sample, victims utilized direct action, inhibition of action, and intrapsychic coping methods, but not information seeking. Of these, direct action was most frequently employed. Independent judges found these categories reliable. Results are examined according to theoretical frameworks in coping theory and current perspectives on sexual abuse.

description: Complex systems are often characterized by large-scale hierarchical organizations. Whether the prominent elements, at the top of the hierarchy, share and control resources or avoid one another lies at the heart of a system's global organization and functioning. Inspired by network perspectives, we propose a new general framework for studying the tendency of prominent elements to form clubs with exclusive control over the majority of a system's resources. We explore associations between prominence and control in the fields of transportation, scientific collaboration, and online communication.

Estimating the effective lifetime of the $z\sim6$ quasar population from the composite proximity zone profile

description: The lifetime of quasars can be estimated by means of their proximity zone sizes, which are regions of enhanced flux bluewards of the Lyman-$α$ emission line observed in the rest-frame UV spectra of high-redshift quasars, because the intergalactic gas has a finite response time to the quasars' radiation. We estimate the effective lifetime of the high-redshift quasar population from the composite transmitted flux profile within the proximity zone region of a sample of $15$ quasars at $5.8\leq z\leq 6.6$ with precise systemic redshifts, and similar luminosities, i.e. $-27.6\leq M_{1450}\leq-26.4$, and thus a similar instantaneous ionizing power. We develop a Bayesian method to infer the effective lifetime from the composite spectrum, including robust estimates of various sources of uncertainty on the spectrum. We estimate an effective lifetime of the quasar population as a whole of $\log_{10}(t_{Q}/{yr}) = 5.7^{+0.5 (+0.8)}_{-0.3 (-0.5)}$ given by the median and $68$th ($95$th) percentile of the posterior probability distribution. While our result is consistent with previous quasar lifetime studies, it poses significant challenges on the current model for the growth of supermassive black holes (SMBHs) located in the center of the quasars' host galaxies, which requires that quasar lifetimes are more than an order of magnitude longer.

Ha Emission from the Magellanic Bridge

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present here a preliminary report and commentary of recently processed observations of Ha emission towards the Magellanic Bridge. These data have been analysed in an attempt to quantify the extent to which the stellar population is capable of reshaping the local ISM. We find that the Ha emission regions are small, weak and sparsely distributed, consistent with a relatively quiescent and inactive ISM where radiative and collisional ionisation is inefficient and sporadic. This suggests that energetic processes at the small scale (i.e. ~tens of pc) do not dominate the energy balance within the ISM of the Bridge, which therefore hosts a pristine turbulent structure, otherwise inaccessible within our own Galaxy. We find Ha emission that is well correlated with detected 12CO(1-0) line emission (a proxy for molecular hydrogen), as well as other easily identified ring-like HI features.

An Archaeology of Convict Leasing in the American South

Year: 2023

description:
Between the mid-nineteenth and mid-twentieth centuries, thousands of men, women, and children in the American South were forced to labor for private businesses and individuals under the convict lease system. This system disproportionately impacted Black men and boys, although it also ensnared Black women and girls as well as poor white men, women, and children. Motivated by the financial gains achieved through leasing prisoners, states ensured that the system continued despite numerous highly-publicized human rights violations. Although numerous scholars and grassroots activists have brought attention to the history of convict leasing, historical archaeology has only engaged with the phenomenon in a limited capacity. In this article, we call for archaeologists, and archaeologists of the African Diaspora in particular, to engage with sites and materialities of convict leasing more directly. Our article outlines a potential path forward for such a research program.

description: We point out that a light scalar field fluctuating around a symmetry-enhaced point can generate large non-Gaussianity in density fluctuations. We name such a particle as an "ungaussiton", a scalar field dominantly produced by the quantum fluctuations,generating sizable non-Gaussianity in the density fluctuations. We derive a consistency relation between the bispectrum and the trispectrum, tau_NL = 10^3 f_NL^(4/3), which can be extended to arbitrary high order correlation functions. If such a relation is confirmed by future observations, it will strongly support this mechanism.

description:
As ocean warming continues to impact marine species globally, there is a need to understand the mechanisms underlying shifts in abundance and distribution. There is growing evidence that upper and lower temperature tolerances rather than mean preferences explain range shifts, but the full thermal niche is unknown for many marine species and observational data are often ill-suited to estimate the upper and lower thermal tolerances. We quantified critical thermal maximum (CTmax ) and critical thermal minimum (CTmin ) using standard methods to quantify temperature limits and thermal ranges of 14 economically and ecologically important juvenile fish species on the US Atlantic coast. We then tested the climate variability hypothesis (CVH), which states that higher-latitude species should have a wider temperature tolerance due to higher climatic variability closer to the poles. Our findings generally support the CVH in the juvenile fishes that we evaluated. However, low-latitude species were not uniformly stenothermal. Rather, species with median occurrences across a wide range of latitudes had wide temperature tolerances, but only the tropical species we tested had more narrow ranges. These findings suggest that quantifying temperature tolerances may be used to predict which low-latitude species are most likely to shift in response to warming water and those that may be more sensitive to climate change in this region.

Low radio frequency observations of seven nearby galaxies with GMRT

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We have observed seven nearby large angular sized galaxies at 0.33 GHz using GMRT with angular resolution of $\sim10''$ and sub-mJy sensitivity. Using archival higher frequency data at 1.4 or $\sim$6 GHz, we have then determined their spatially resolved non-thermal spectrum. As a general trend, we find that the spectral indices are comparatively flat at the galaxy centres and gradually steepen with increasing galactocentric distances. Using archival far infrared (FIR) MIPS 70 $μ m$ data, we estimate the exponent of radio-FIR correlation. One of the galaxy (NGC 4826) was found to have an exponent of the correlation of $\sim1.4$. Average exponent from 0.33 GHz data for the rest of the galaxies was 0.63$\pm$0.06 and is significantly flatter than the exponent 0.78$\pm$0.04 obtained using 1.4 GHz data. This indicates cosmic ray electron (CRe) propagation to have reduced the correlation between FIR and 0.33 GHz radio. Assuming a model of simple isotropic diffusion of CRe, we find that the scenario can explain the frequency dependent cosmic ray electron propagation length scales for only two galaxies. Invoking streaming instability could, however, explain the results for the majority of the remaining ones.

description: The newly found states Y(4260), Y(4361), Y(4664) and Z$^\pm$(4430) stir broad interest in the study of spectroscopy in a typical charmonium scale. The Y(4260) which was observed earlier has been interpreted as hybrid, molecular state, and baryonium, etc. In this note we show for the first time that these new structures, which are hard to be interpreted as charmonium states, can be systematically embedded into an extended baryonium picture. According to this assignment, the so far known characters of these states are understandable. And, in the same framework, we make some predictions for experimenters to measure in the future.

description:
A recent wave of studies has focused on the identities of communication scholars, quantifying the degree to which Whites, men, and Americans dominate the discipline.This study analyzes the communication citation elite (CCE)—a group of 1,675 highly cited scholars in communication research—in terms of race, gender, and country of employment over 20 years. Applying computational methods and content analysis, we find that 91.5% of first-author CCE members are White, 74.3% are men, and 78.6% work in the United States. Longitudinal analyses of each identity category reveal only minor shifts, most prominently slight gains for women and non-U.S. scholars. White representation among first authors decreased less than 4 percentage points over the study period (from 95.1% to 91.2%), with Black representation ending lower than it began (0.61% to 0.54%). Data from the International Communication Association indicate that the CCE is substantially more American and male than the organization’s full membership as of 2021.

description: The LIGO and Virgo observatories have reported 39 new gravitational-wave detections during the first part of the third observation run, bringing the total to 50. Most of these new detections are consistent with binary black-hole coalescences, making them suitable targets to search for gravitational-wave memory, a non-linear effect of general relativity. We extend a method developed in previous publications to analyse these events to determine a Bayes factor comparing the memory hypothesis to the no-memory hypothesis. Specifically, we calculate Bayes factors using two waveform models with higher-order modes that allow us to analyse events with extreme mass ratios and precessing spins, both of which have not been possible before. Depending on the waveform model we find a combined $\ln \mathrm{BF}_{\mathrm{mem}} = 0.024$ or $\ln \mathrm{BF}_{\mathrm{mem}} = 0.049$ in favour of memory. This result is consistent with recent predictions that indicate $\mathcal{O}(2000)$ binary black-hole detections will be required to confidently establish the presence or absence of memory.

description: The document layout analysis (DLA) aims to split the document image into different interest regions and understand the role of each region, which has wide application such as optical character recognition (OCR) systems and document retrieval. However, it is a challenge to build a DLA system because the training data is very limited and lacks an efficient model. In this paper, we propose an end-to-end united network named Dynamic Residual Fusion Network (DRFN) for the DLA task. Specifically, we design a dynamic residual feature fusion module which can fully utilize low-dimensional information and maintain high-dimensional category information. Besides, to deal with the model overfitting problem that is caused by lacking enough data, we propose the dynamic select mechanism for efficient fine-tuning in limited train data. We experiment with two challenging datasets and demonstrate the effectiveness of the proposed module.

In addition to the optical phonons allowed by symmetry; A1, E1 and E2(high) modes, two additional Raman peaks are observed around 528 cm-1 and 560 cm-1 for these nanostructures. Calculations for the frequencies of surface optical (SO) phonon modes in InN nanostructures yield values close to those of the new Raman modes. A possible reason for large intensities for SO modes in these nanostructures is also discussed.

description: We study the formation of fifty-three galaxy cluster-size dark matter halos formed within a pair of cosmological LCDM N-body simulations, and track the accretion histories of cluster subhalos with masses large enough to host 0.1L* galaxies. By associating subhalos with cluster galaxies, we find the majority of galaxies in clusters experience no pre-processing in the group environment prior to their accretion into the cluster. On average, ~70% of cluster galaxies fall into the cluster potential directly from the field, with no luminous companions in their host halos at the time of accretion; and less than ~12% are accreted as members of groups with five or more galaxies. Moreover, we find that cluster galaxies are significantly less likely to have experienced a merger in the recent past (~6 Gyr) than a field halo of the same mass. These results suggest that local, cluster processes like ram-pressure stripping, galaxy harassment, or strangulation play the dominant role in explaining the difference between cluster and field populations at a fixed stellar mass; and that pre-evolution or past merging in the group environment is of secondary importance for setting cluster galaxy properties for most clusters. The accretion times for z = 0 cluster members are quite extended, with ~20% incorporated into the cluster halo more than 7 Gyr ago and ~20% within the last 2 Gyr. By comparing the observed morphological fractions in cluster and field populations, we estimate an approximate timescale for late-type to early-type transformation within the cluster environment to be ~6 Gyr.

description: We studied the spectral features of Si II $λλ$4130, 5972, 6355 and S II W-trough for a large sample of Type Ia supernovae (SNe Ia). We find that in NV (Normal-Velocity) subclass of SNe Ia, these features tend to reach a maximum line strength near maximum light, except for Si II $λ$5972. Spectral features with higher excitation energy, such as S II W-trough, are relatively weak and have relatively low velocity. SNe Ia with larger $Δ$m$_{15}$($B$) tend to have lower velocities especially at phases after maximum light. NV SNe show a trend of increasing line strength with increasing $Δ$m$_{15}$($B$), while 91T/99aa-like SNe show an opposite trend. Near maximum light, the absorption depth of Si II $λ$5972 shows the strongest correlation with $Δ$m$_{15}$($B$), while at early times the sum of the depths of Si II $λλ$4130 and 5972 shows the strongest correlation with $Δ$m$_{15}$($B$). The overall correlation between velocity and line strength is positive, but within NV SNe the correlation is negative or unrelated. In normal SNe Ia, the velocity-difference and depth-ratio of a longer-wavelength feature to a shorter-wavelength feature tend to increase with increasing $Δ$m$_{15}$($B$). These results are mostly well explained with atomic physics, but some puzzles remain, possibly related to the effects of the saturation, line competition or other factors.

description: We search for possible time lags caused by quantum gravitational (QG) effects using gamma-ray bursts (GRBs) detected by INTEGRAL. The advantage of this satellite is that we have at our disposal the energy and arrival time of every detected single photon, which enhances the precision of the time resolution. We present a new method for seeking time lags in unbinned data using a maximum likelihood method and support our conclusions with Monte Carlo simulations. The analysis of the data yields a mass scale well below the Planck mass whose value may however increase if better statistics of GRBs were available. Furthermore, we disagree with previous studies in which a non-monotonic function of the redshift was used to perform a linear fit.

description: We present an exploratory study of gaugino-pair production in polarized and unpolarized hadron collisions, focusing on the correlation of beam polarization and gaugino/Higgsino mixing in the general Minimal Supersymmetric Standard Model. Helicity-dependent cross sections induced by neutral and charged electroweak currents and squark exchanges are computed analytically in terms of generalized charges, defined similarly for chargino-pair, neutralino-chargino associated, and neutralino-pair production. Our results confirm and extend those obtained previously for negligible Yukawa couplings and nonmixing squarks. Assuming that the lightest chargino mass is known, we show numerically that measurements of the longitudinal single-spin asymmetry at the existing polarized pp collider RHIC and at possible polarization upgrades of the Tevatron or the LHC would allow for a determination of the gaugino/Higgsino fractions of charginos and neutralinos. The theoretical uncertainty coming from factorization scale and squark mass variations and the expected experimental error on the lightest chargino mass is generally smaller than the one induced by the polarized parton densities, so that more information on the latter would considerably improve on the analysis.

How gay and bisexual men respond to mpox messages through risk- versus identity-based mechanisms: An integrated model

Publisher: name: Taylor & Francis

description:
To reduce the risk of transmission in the mpox outbreak, it is crucial to provide accurate, tailored, and culturally sensitive risk communication. In an online experiment (N = 372), we tested a theory-informed model on gay and bisexual men’s response to mpox risk communication focusing on the ingroup versus the general population. Gay and bisexual men who received an ingroup-framed risk message had a stronger protective behavioral intention through heightened risk perception. However, this intended effect of risk message framing was negated by an unintended effect through perceived morality threat to sexual identity and defensive processing. These effects further varied depending on participants' level of identification with their sexuality. Findings highlight the importance of considering the social identity implications of risk communication.

description: Ethereum Smart contracts use blockchain to transfer values among peers on networks without central agency. These programs are deployed on decentralized applications running on top of the blockchain consensus protocol to enable people to make agreements in a transparent and conflict-free environment. The security vulnerabilities within those smart contracts are a potential threat to the applications and have caused huge financial losses to their users. In this paper, we present a framework that combines static and dynamic analysis to detect Reentrancy vulnerabilities in Ethereum smart contracts. This framework generates an attacker contract based on the ABI specifications of smart contracts under test and analyzes the contract interaction to precisely report Reentrancy vulnerability. We conducted a preliminary evaluation of our proposed framework on 5 modified smart contracts from Etherscan and our framework was able to detect the Reentrancy vulnerability in all our modified contracts. Our framework analyzes smart contracts statically to identify potentially vulnerable functions and then uses dynamic analysis to precisely confirm Reentrancy vulnerability, thus achieving increased performance and reduced false positives.

description:
The history of the child welfare system and related institutions with American Indian children and families has been marked by numerous atrocities, including unnecessary separations, assimilation, and trauma. The Indian Child Welfare Act (ICWA) was enacted in 1978 to promote the stability and security of American Indian tribes and families. For children involved in the child welfare system, ICWA prioritizes the placement of American Indian children with family or tribal members. This paper examines placement outcomes for American Indian children using recent national data over 3 years from the Adoption and Foster Care Analysis and Reporting System. Multivariate regression analyses showed that American Indian children were significantly less likely to be placed with same-race/ethnicity caretakers than their non-American Indian counterparts. In addition, American Indian children were not more likely to be placed with relatives or have trial home placement compared to non-American Indian children. These findings suggest that ICWA is not reaching its intended objectives regarding placement goals specified in the law regarding American Indian children. These policy shortcomings have significant implications for American Indian children, families, and tribes in terms of well-being, family connection, and cultural loss.

description: The polarizations of optical fields, besides field intensities, provide more degrees of freedom to manipulate coherent light-matter interactions. Here we propose how to achieve a coherent switch of optomechanical entanglement in a polarized-light-driven cavity system. We show that by tuning the polarizations of the driving field, the effective optomechanical coupling can be well controlled and, as a result, quantum entanglement between the mechanical oscillator and the optical transverse electric (TE) mode can be coherently and reversibly switched to that between the same phonon mode and the optical transverse magnetic (TM) mode. This ability of switching optomechanical entanglement with such a vectorial device can be important for building a quantum network being capable of efficient quantum information interchanges between processing nodes and flying photons.

La peur d’une construction libérale de l’Union européenne et de la fin de l’État-providence : positions euro-critiques au sein du socialisme français à l’occasion des référendums sur le Traité de Maastricht et sur la Constitution européenne

description: En France, les référendums sur la ratification du Traité de Maastricht et du Traité constitutionnel, qui se sont respectivement déroulés le 20 septembre 1992 et le 29 mai 2005, furent des événements décisifs pour l’histoire de la construction européenne et de division pour la sphère socialiste française, mettant en évidence les fractures au sein du Parti socialiste (PS) sur la nature du processus d’intégration européenne, sur le plan économique, social et institutionnel. Ces divisions étaient en partie déjà apparues en mars 1983, sur la politique économique adoptée par le gouvernement Mauroy pour garantir la permanence de la France dans le Système monétaire européen. Les socialistes français se divisèrent, en outre, sur le Projet Spinelli, en optant pour l’abstention à l’occasion du vote au Parlement européen en février 1984. En 1992, après le choix de François Mitterrand d’organiser un référendum sur la ratification du Traité de Maastricht, et après les résultats du Congrès de Bordeaux, où le PS se prononça en faveur du « oui » au référendum, Jean-Pierre Chevènement quitta la Direction du parti pour s’engager dans la campagne en faveur du « non » et fonder le Mouvement des Citoyens (MDC), avec Max Gallo à la présidence. Le MDC constituait encore une composante du PS, dont il se sépara en avril 1993 pour se transformer en un parti en décembre de la même année. Puis, il y eut le référendum sur le Traité constitutionnel européen. Le PS organisa, entre ses membres, le 1er décembre 2004, un référendum sur le Traité qui vit prévaloir le « oui » à la ratification, mais des dirigeants socialistes importants, comme Laurent Fabius, Marc Dolez, Jean-Luc Mélenchon et Henri Emmanuelli, soutinrent le « non », pendant la campagne pour le référendum national. En dehors du PS, Chevènement fit – lui aussi - campagne en faveur du « non ».

U.S. West Coast droughts and heat waves exacerbate pollution inequality and can evade emission control policies

description:
Droughts reduce hydropower production and heatwaves increase electricity demand, forcing power system operators to rely more on fossil fuel power plants. However, less is known about how droughts and heat waves impact the county level distribution of health damages from power plant emissions. Using California as a case study, we simulate emissions from power plants under a 500-year synthetic weather ensemble. We find that human health damages are highest in hot, dry years. Counties with a majority of people of color and counties with high pollution burden (which are somewhat overlapping) are disproportionately impacted by increased emissions from power plants during droughts and heat waves. Taxing power plant operations based on each plant’s contribution to health damages significantly reduces average exposure. However, emissions taxes do not reduce air pollution damages on the worst polluting days, because supply scarcity (caused by severe heat waves) forces system operators to use every power plant available to avoid causing a blackout.

description: White dwarfs are the end state of the evolution of more than 97% of all stars, and therefore carry information on the structure and evolution of the Galaxy through their luminosity function and initial-to-final mass relation. Examining the new spectra of all white or blue stars in the Sloan Digital Sky Survey Data Release 16, we report the spectral classification of 2410 stars, down to our identification cut-off of signal-to-noise ratio equal to three. We newly identify 1404 DAs, 189 DZs, 103 DCs, 12 DBs, and 9 CVs. The remaining objects are a mix of carbon or L stars (dC/L), narrow-lined hydrogen-dominated stars (sdA), dwarf F stars and P Cyg objects. As white dwarf stars were not targeted by SDSS DR16, the number of new discoveries is much smaller than in previous releases. We also report atmospheric parameters and masses for a subset consisting of 555 new DAs, 10 new DBs, and 85 DZs for spectra with signal-to-noise ratio larger than 10.

Cultural foundations of personal meaning : their loss and recovery
Creators: name: More, Janet May Derrick
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated what occurs in an individual's life when their culture is changed or irretrievably lost; and it investigated how an individual then regains personal meaning during a time of cultural loss and change. Peter Marris' innovative Theory of Loss and Change was used as the theoretical basis for the study. This theory states that a grief-like reformulation process occurs for individuals who experience any irretrievable loss of culture. The Native Indian cultures of British Columbia were used as the cultural foundation. Three Native Indian elders were interviewed and their life histories recorded (Bertaux, 1981). The data collected was then used as multiple case studies and analyzed according to Yin (1984) and Stake (1980). Cross-matching of patterns of loss and change, and patterns of recovery of personal meaning revealed six primary forms of loss and change in the elder's lives, and five primary characteristics of recovery of personal meaning. Secondary forms and characteristics in each area were identified as well. Marris' Theory of Loss and Change was supported. It was also expanded to include the Native Indian cultures of British Columbia. In addition, the emotional elements of the reformulation process were specified. The outcome of the study was a cognitive framework useful in understanding the Native Indian cultures in British Columbia and the personal conflicts of Native Indian individuals.
