In vitro studies of multiwalled carbon nanotube/ultrahigh molecular weight polyethylene nanocomposites with osteoblast-like MG63 cells

Carbon nanotubes are highly versatile materials; new applications using them are continuously being developed. Special attention is being dedicated to the possible use of multiwalled carbon nanotubes in biomaterials contacting with bone. However, carbon nanotubes are also controversial in regards to effects exerted on living organisms. Carbon nanotubes can be used to improve the tribological properties of polymer/composite materials. Ultrahigh molecular weight polyethylene (UHMWPE) is a polymer widely used in orthopedic applications that imply wear and particle generation. We describe here the response of human osteoblast-like MG63 cells after 6 days of culture in contact with artificially generated particles from both UHMWPE polymer and multiwalled carbon nanotubes (MWCNT)/UHMWPE nanocomposites. This novel composite has superior wear behavior, having thus the potential to reduce the number of revision hip arthroplasty surgeries required by wear failure of acetabular cups and diminish particle-induced osteolysis. The results of an in vitro study of viability and proliferation and interleukin-6 (IL-6) production suggest good cytocompatibility, similar to that of conventional UHMWPE (WST-1 assay results are reported as percentage of control ± SD: UHMWPE = 96.19 ± 7.92, MWCNT/UHMWPE = 97.92 ± 8.29%; total protein: control = 139.73 ± 10.78, UHMWPE = 137.07 ± 6.17, MWCNT/UHMWPE = 163.29 ± 11.81 µg/mL; IL-6: control = 90.93 ± 10.30, UHMWPE = 92.52 ± 11.02, MWCNT/UHMWPE = 108.99 ± 9.90 pg/mL). Standard cell culture conditions were considered as control. These results, especially the absence of significant elevation in the osteolysis inductor IL-6 values, reinforce the potential of this superior wear-resistant composite for future orthopedic applications, when compared to traditional UHMWPE.

Interaction between growth differentiation factor 9, insulin-like growth factor I and growth hormone on the in vitro development and survival of goat preantral follicles

The objective of this study was to determine the effects of GDF-9, IGF-I, and GH alone or combined on preantral follicle survival, activation and development after 1 and 7 days of in vitro culture. Either fresh (non-cultured) or cultured ovarian tissue was processed for histological and fluorescence analysis. For all media tested, the percent of normal follicles was greater when compared to minimum essential medium supplemented (MEM+) alone, except when ovarian tissue was cultured with GDF-9/IGF-I or GDF-9/GH (P < 0.05). Fluorescence analysis showed that the percent of viable follicles after 7 days of culture was similar for non-cultured tissue and for all treatments tested. The percent of primordial follicles was reduced (P < 0.05) and there was a significant and concomitant increase in the percent of intermediate and primary follicles in all treatments tested after 7 days of culture when compared to non-cultured tissue. After 7 days of culture, the highest percent of intermediate follicles was observed with IGF-I/GH (61.3%), and the highest percent of primary follicles was achieved with IGF-I (57.7%). After 7 days of culture in MEM+ containing GDF-9, IGF-I and GH alone or in all associations, a significant increase in follicular diameter was observed when compared to MEM+ alone and non-cultured tissue. In conclusion, GDF-9, IGF-I and GH alone or in combination maintain preantral follicle survival and promote primordial follicle activation. Nevertheless, the data showed that IGF-I/GH and IGF-I alone are efficient in promoting the transition from primordial to intermediate follicles and from intermediate to primary follicles, respectively.

Modulation of murine blastocyst hatching in vitro by glutamine and tryptophan

Enrichment of culture media with amino acids improves embryo development. However, little is known about the specific action of each amino acid during embryogenesis. The present study was undertaken to examine the effect of L-glutamine (Gln) and tryptophan (Trp) on mouse embryo hatching, expansion and viability in vitro. Blastocysts were collected from 6- to 8-week-old female BALB/c mice (N = 30) and cultured in M2 medium containing either 0.125, 0.25 or 0.5 mM Trp, 1 mM Gln, or M2 alone. Gln significantly increased (100%; P < 0.05) blastocyst hatching at 24 h compared to M2 alone or Trp; moreover, Trp inhibited blastocyst hatching when compared to M2 alone (P < 0.05) at 72 h. In contrast, the percentage of embryos reaching the state of expanded blastocyst at 48 h was significantly higher in medium with 1 mM Gln (66.6%; P < 0.05) or with 0.125 mM Trp (61.1%; P < 0.05). Unexpectedly, Trp increased the percentage of degenerated blastocysts after 48 h (67.7%; P < 0.05), while Gln preserved blastocyst viability. These results suggest that Gln may enhance blastocyst hatching, expansion and viability in vitro.

Phytohemagglutinin improves the development and ultrastructure of in vitro-cultured goat (Capra hircus) preantral follicles

The objective this study was to determine the effect of phytohemagglutinin (PHA) on survival, growth and gene expression in caprine secondary follicles culturedin vitro. Secondary follicles (∼0.2 mm) were isolated from the cortex of caprine ovaries and cultured individually for 6 days in α-MEM+ supplemented with PHA (0, 1, 10, 50, 100, or 200 µg/mL). After 6 days of culture, follicle diameter and survival, antrum formation, ultrastructure and expression of mRNA for FSH receptors (FSH-R), proliferating cell nuclear antigen (PCNA), and neuronal nitric oxide synthase were determined. All treatments maintained follicular survival [α-MEM+ (94.59%); 1 µg/mL PHA (96.43%); 10 µg/mL PHA (84.85%); 50 µg/mL PHA (85.29%); 100 µg/mL PHA (88.57%), and 200 µg/mL PHA (87.50)], but the presence of 10 µg/mL PHA in the culture medium increased the antrum formation rate (21.21%) when compared with control (5.41%, P < 0.05) and ensured the maintenance of oocyte and granulosa cell ultrastructures after 6 days of culture. The expression of mRNA for FSH-R (2.7 ± 0.1) and PCNA (4.4 ± 0.2) was also significantly increased in follicles cultured with 10 µg/mL PHA in relation to those cultured in α-MEM+ (1.0 ± 0.1). In conclusion, supplementation of culture medium with 10 µg/mL PHA maintains the follicular viability and ultrastructure, and promotes the formation of antral cavity after 6 days of culture in vitro.

Representations of cultural encounters in the global business press – The importance of cross-cultural competence

This qualitative study has started from the interest to examine how the reality of crosscultural encounters is presented in the global business press. The research paper emphasizes different ways to classify culture and cross-cultural competency, both from the point of view of individuals and organizations. The analysis consists of public discourses, where cross-cultural realities are created through different persons, stories and contexts For data collection, a comprehensive database search was performed and 10 articles from the widely known worldwide business magazine The Financial Times were chosen as the data for the study paper. For the functions of addressing the research study questions, Thematic Content Analysis (TCA) and also Discourse Analysis (DA) are utilized, added with the continuous comparison method of grounded theory in the formation of the data.The academic references consist of literary works and articles presenting relevant concepts, creating a cross-cultural framework, and it is designed to assist the reader in the navigation through the topics of culture and cross-cultural competency. The repertoires were formed from the data and following, the first repertoire is contrast difference between home and target culture that the individual was able to discern. As a consequence of the first repertoire, the companies then offer cultural training to their employees to prepare them to situations of increasing levels of cultural variation. The third repertoire is increased awareness of other cultures, which is conveyed as a result of cultural training and contextual work experience. The fourth repertoire is globalization as an international business environment, where the people in the articles perform their job functions. It is stated in the conclusions that the representations emphasize Western values and personal traits in leadership.

Partial chemical and functional characterization of milk whey products obtained by different processes

Whey protein samples (S-1 to S-5) were tested in vivo and in vitro for nutritional properties and selected bioactivities. Weanling male Wistar rats fed modified AIN-93G (12 g protein.100 g-1) diets for 21 days were used the in vivo studies. The nutritional parameters did not differ among the protein diets tested. Erythrocyte glutathione content was considered high and was higher for S-3, but liver glutathione was the same for all dietary groups. For S-3, cytokine secretion (IL-10 and TNF-α) by human peripheral blood mononuclear cells (in RPMI-1640 medium) was higher in the absence of antigen than in the presence of BCG antigen. Interleukin-4 secretion was repressed in all treatments. The IC50, whey protein concentration required to inhibit 50% of the melanoma cell proliferation, was 2.68 mg.mL-1 of culture medium for the S-3 sample and 3.66 mg.mL-1 for the S-2 sample. Based on these results, it was concluded that S-3 (whey protein concentrate enriched with TGF-β and lactoferrin) produced better nutritional and immunological responses than the other products tested.

Study of the physical and physicochemical characteristics of fruits of the licuri palm (Syagrus coronata (Mart.) Becc.) found in the Atlantic Forest of Minas Gerais, Brazil

AbstractThe Atlantic Forest has species of native fruits, consumed fresh and processed, which have an important contribution to food sovereignty of families that consume it. This study examined the physical and physicochemical characteristics, proximate composition, concentration of carotenoids, vitamin C, vitamin E and minerals in the pulp and kernels of fruits of licuri (Syagrus coronata (Mart.) Becc.). Titratable acidity was analyzed by volumetric neutralization, soluble solids by refractometry, proteins by the micro-Kjeldahl method, lipids by gravimetry using soxhlet, dietary fiber by non-enzymatic gravimetry, carotenoids and vitamin C by HPLC-DAD, vitamin E by HPLC-fluorescence, and minerals by ICP-AES. Pulp were a source of Zn (0.95 mg 100–1), a good source of fiber (6.15 g 100–1), excellent source of provitamin A (758.75 RAE 100–1), Cu (0.69 mg 100–1), Fe (3.81 mg 100–1), Mn (3.40 mg 100–1) and Mo (0.06 mg 100–1). The kernel were a source of Fe (3.36 mg 100–1) and excellent source of Mn (6.14 mg 100–1), Cu (0.97 mg 100–1) and Mo (0.07 mg 100–1). The nutritional value and wide availability of licuri fruit make it an important resource for reducing food insecurity and improving nutrition of the rural population and other individuals who have access to it.

Marginal/minority popular music : the concept of the "third space" and the case for "hybridities" of cultures/identities /

The topic of this thesis is marginaVminority popular music and the question of identity; the term "marginaVminority" specifically refers to members of racial and cultural minorities who are socially and politically marginalized. The thesis argument is that popular music produced by members of cultural and racial minorities establishes cultural identity and resists racist discourse. Three marginaVminority popular music artists and their songs have been chosen for analysis in support of the argument: Gil Scott-Heron's "Gun," Tracy Chapman's "Fast Car" and Robbie Robertson's "Sacrifice." The thesis will draw from two fields of study; popular music and postcolonialism. Within the area of popular music, Theodor Adorno's "Standardization" theory is the focus. Within the area of postcolonialism, this thesis concentrates on two specific topics; 1) Stuart Hall's and Homi Bhabha's overlapping perspectives that identity is a process of cultural signification, and 2) Homi Bhabha's concept of the "Third Space." For Bhabha (1995a), the Third Space defines cultures in the moment of their use, at the moment of their exchange. The idea of identities arising out of cultural struggle suggests that identity is a process as opposed to a fixed center, an enclosed totality. Cultures arise from historical memory and memory has no center. Historical memory is de-centered and thus cultures are also de-centered, they are not enclosed totalities. This is what Bhabha means by "hybridity" of culture - that cultures are not unitary totalities, they are ways of knowing and speaking about a reality that is in constant flux. In this regard, the language of "Otherness" depends on suppressing or marginalizing the productive capacity of culture in the act of enunciation. The Third Space represents a strategy of enunciation that disrupts, interrupts and dislocates the dominant discursive construction of US and THEM, (a construction explained by Hall's concept of binary oppositions, detailed in Chapter 2). Bhabha uses the term "enunciation" as a linguistic metaphor for how cultural differences are articulated through discourse and thus how differences are discursively produced. Like Hall, Bhabha views culture as a process of understanding and of signification because Bhabha sees traditional cultures' struggle against colonizing cultures as transforming them. Adorno's theory of Standardization will be understood as a theoretical position of Western authority. The thesis will argue that Adorno's theory rests on the assumption that there is an "essence" to music, an essence that Adorno rationalizes as structure/form. The thesis will demonstrate that constructing music as possessing an essence is connected to ideology and power and in this regard, Adorno's Standardization theory is a discourse of White Western power. It will be argued that "essentialism" is at the root of Western "rationalization" of music, and that the definition of what constitutes music is an extension of Western racist "discourses" of the Other. The methodological framework of the thesis entails a) applying semiotics to each of the three songs examined and b) also applying Bhabha's model of the Third Space to each of the songs. In this thesis, semiotics specifically refers to Stuart Hall's retheorized semiotics, which recognizes the dual function of semiotics in the analysis of marginal racial/cultural identities, i.e., simultaneously represent embedded racial/cultural stereotypes, and the marginal raciaVcultural first person voice that disavows and thus reinscribes stereotyped identities. (Here, and throughout this thesis, "first person voice" is used not to denote the voice of the songwriter, but rather the collective voice of a marginal racial/cultural group). This dual function fits with Hall's and Bhabha's idea that cultural identity emerges out of cultural antagonism, cultural struggle. Bhabha's Third Space is also applied to each of the songs to show that cultural "struggle" between colonizers and colonized produces cultural hybridities, musically expressed as fusions of styles/sounds. The purpose of combining semiotics and postcolonialism in the three songs to be analyzed is to show that marginal popular music, produced by members of cultural and racial minorities, establishes cultural identity and resists racist discourse by overwriting identities of racial/cultural stereotypes with identities shaped by the first person voice enunciated in the Third Space, to produce identities of cultural hybridities. Semiotic codes of embedded "Black" and "Indian" stereotypes in each song's musical and lyrical text will be read and shown to be overwritten by the semiotic codes of the first person voice, which are decoded with the aid of postcolonial concepts such as "ambivalence," "hybridity" and "enunciation."

Manufacturing 'authenticity' : a case study of the Niagara wine cluster

In this thesis, I use "Fabricating Authenticity," a model developed in the Production of Culture Perspective, to explore the evolving criteria for judging what constitute "real" and authentic Niagara wines, along with the naturalization of these criteria, as the Canadian Niagara wine cluster has come under increasing stress from globalization. Authenticity has been identified as a hallmark of contemporary marketing and important to cultural industries, which can use it for creating meaningful differentiation; making it a renewable resource for securing consumers, increasing market value; and for relationships with key brokers. This is important as free trade and international treaties are making traditional protective barriers, like trade tariffs and markups, obsolete and as governments increasingly allocate industry support via promotion and marketing policies that are directly linked to objectives of city and regional development, which in turn carry real implications for what gets to be judged authentic and inauthentic local culture. This research uses a mixed methods research strategy, drawing upon ethnographic observation, marketing materials, newspaper reports, and secondary data to provide insight into the processes and conflicts over efforts to fabricate authenticity, comparing the periods before and after the passage of NAFT A to the present period. The Niagara wine cluster is a good case in point because it has little natural advantage nor was there a tradition of quality table wine making to facilitate the naturalization of authenticity. Geographic industrial clusters have been found particularly competitive in the global economy and the exploratory case study contributes to our understanding of the dynamic of '1abricating authenticity," building on various theoretical propositions to attempt to derive explanations of how global processes affect strategies to create "authenticity," how these strategies affect cultural homogeneity and heterogeneity at the local level, and how the concept of "cluster" contributes to the process of managing authenticity.

Exploring the Perceptions of Cultural Competence Among Personal Support Workers in an Ontario Long-Term Care Home: A Case Study

Personal Support Workers (PSWs) spend a large amount of time with long-term care (LTC) home residents providing assistance with their activities of daily living. The s limited research on their perceptions of cultural competence presents the need to bridge this knowledge gap. The researcher conducted a qualitative case study at a LTC home in Ontario. Data were collected by conducting a policy document analysis, a key informant interview with the Director of Care (DOC), and two focus groups with PSWs. The five major overarching themes were: The Culture of the LTC Home, Provision of a Supportive Environment, Collaborative Team Approach to Care, Building a Relationship with the Residents, and Maintenance of Staff Morale. The findings illuminated the broad nature of culture, connections to person centered care, and the factors that facilitate or hinder PSWs’ culturally competent care. The ambiguous perception of cultural competence among PSWs suggests further research and education on cultural competence in LTC home settings.

Socialisation du salariat professionnel et transmission de la culture dans les organisations syndicales québécoises

Français : Partant de la question du renouvellement de la main-d’œuvre québécoise, ce mémoire s’intéresse aux salariés professionnels des organisations syndicales québécoises. Ces dernières se sont dotées d’un important salariat professionnel dont le renouvellement en cours ou à prévoir suppose des défis importants, notamment à propos de la transmission de la culture organisationnelle. Ainsi, ce mémoire portera sur la socialisation des salariés professionnels des organisations syndicales québécoises à partir de quatre études de cas (FTQ, Syndicat des Métallos, CSN et FIQ). Il sera notamment question des pratiques de gestion de personnel de ces organisations liées au transfert de la culture, soit les pratiques de socialisation et de recrutement, de la formalisation de ces pratiques et de leur contrôle. Les résultats permettent de mettre en évidence les rapports entre la structure administrative des organisations syndicales et le modèle de socialisation des salariés professionnels nouvellement embauchés y ayant cours. De plus, bien que la tendance va en s’amplifiant, les pratiques de socialisation, à l’instar des autres pratiques de gestion de personnel en milieu syndical, demeurent peu formalisées. Enfin, les résultats permettent également de constater que le contrôle des dirigeants syndicaux sur la transmission de la culture aux professionnels est relativement faible comparativement à celui des pairs.

Je qui devient Nous et Nous qui devient Je : sens unitaire de la culture chez Hegel

Le thème de la culture (Bildung) se caractérise d’abord, dans l’ensemble de l’œuvre de Hegel, par sa diversité contextuelle. Bien que la culture y soit définie spécifiquement comme un mode de développement propre à l’humain, à la différence de l’usage usuel du terme en allemand, cette diversité fait en sorte qu’on la retrouve aussi bien dans les remarques anthropologiques les plus anodines que dans les passages s’intéressant à l’histoire de l’esprit du monde ou encore les textes de nature politique. Il s’agit donc, dans le présent travail, d’étudier pour eux-mêmes les différents contextes généraux dans lesquels la notion apparaît (Phénoménologie de l’esprit, philosophie politique et philosophie de l’histoire) pour en arriver à retracer le fil conducteur donnant à la culture hégélienne son unité de sens. Loin d’être un concept indéterminé, la culture désigne, à tous les niveaux où il se manifeste, le dynamisme propre à l’esprit.

Temps, culture et communication : pour une critique de la statistique culturelle

Comment fonder théoriquement des indicateurs culturels? Issue de problèmes méthodologiques reliés à l’étude des rapports entre le temps de travail et le temps libre, cette question émerge à la suite du constat du déficit théorique de la statistique culturelle. En effet, l’étude du temps libre, comme du temps de travail, nécessite de questionner les fondements de cette répartition, en même temps qu’elle exige d’analyser concrètement les pratiques sociales reliées à ces catégories. Or, les ana-lyses sur l’emploi du temps libre sont souvent fondées sur des statistiques à propos des activités culturelles, statistiques dont la portée explicative est singulièrement limitée. Bien que des statistiques sur certaines de ces activités existent au moins depuis le début du XXe siècle, c’est à partir des années 1970 que les besoins de connaissance reliés à la mise en œuvre des politiques culturelles stimulent la production de statistiques plus nombreuses et plus détaillées. Afin de donner des significations à cette masse de statistiques, il est nécessaire de délimiter les frontières de ce qui est culture et communication parmi toutes les autres activités sociales. L’élaboration de cadres conceptuels de la culture par l’UNESCO et d’autres agences statistiques tente de répondre à cette exigence, tandis que les projets d’indicateurs avancés cherchent à donner un sens à l’information statistique. Ces tentatives se caractérisent toutefois par la faiblesse de leur assise théorique, problème qui se manifeste de manière aiguë dans la définition d’indicateurs qui ont nécessairement une portée normative. La résolution de cette impasse de la statistique culturelle passe au moins par une clarification des concepts reliés à la notion de culture. À cette fin, la méthodologie de la recherche repose sur une analyse critique de certains documents fondamentaux qui ont conduit à la création du cadre conceptuel pour la statistique culturelle de l’UNESCO, ainsi que sur des textes phares de Fernand Dumont, Pierre Bourdieu et Jürgen Habermas, choisis pour leur capacité à penser les activités culturelles dans l’ensemble social selon leur temporalité. La notion de temporalité est elle-même examinée sous l’angle de plusieurs approches théoriques. Il ressort de cet examen que la différenciation du temps en temps abstrait et temps concret permet d’entrevoir que les pratiques culturelles pourraient être mesurées non seulement selon la quantité de temps social qui leur est dévolue, mais aussi comme un temps qui a une valeur marchande. Les acquis de l’analyse critique des cadres conceptuels de la statistique culturelle et des textes de Dumont, Bourdieu et Habermas servent de points d’appui pour l’élaboration d’un projet d’indicateurs culturels pour le compte de l’Observatoire de la culture et des communications du Québec (OCCQ). Ce système d’indicateurs a été élaboré selon une grille qui définit ce qu’est un indicateur culturel, son objectif et sa signification. Les indicateurs ont été choisis au cours d’un processus de consultation mené par l’OCCQ auprès des agents gouvernementaux concernés et des représentants des associations professionnelles des secteurs de la culture et des communications du Québec.

Dance and the colonial body : re-choreographing postcolonial theories of the body

Cette dissertation traite la danse comme une catégorie d’analyse permettant de réorienter ou de ré-chorégraphier les théories postcoloniales du corps. Mon étude montre qu’ Edward Said, par exemple, décrit la danse seulement à travers le regard impérial, et que Homi Bhabha et Gayatri Spivak négligent complètement le rôle de la dance dans la construction de la subjectivité postcoloniale. Mon étude explique que Stavros Karayanni récemment explore la danse masculine et féminine comme espaces de résistance contre la domination coloniale. Toutefois, l’analyse de Karayanni met l’accent seulement sur le caractère insaisissable de la danse qui produit une ambigüité et une ambivalence dans le regard du sujet impériale. Contrairement aux approches de Said et de Karayanni, ma dissertation explore la danse comme un espace ou le corps du sujet colonisé chorégraphie son histoire collective que l’amnésie coloniale ne cesse de défigurer au moyen de l’acculturation et de marchandisation. Je soutiens que la danse nous offre la possibilité de concevoir le corps colonisé non seulement dans son ambiguïté, comme le souligne Karayanni, mais aussi dans son potentiel de raconter corporellement sa mémoire collective de l’intérieur de la domination impériale. Ma dissertation soutient que les catégories de l’ambiguïté et de l’insaisissabilité mystifient et fétichisent le corps dansant en le décrivant comme un élément évasif et évanescent. Ma dissertation inclut plusieurs traditions culturelles de manière à réorienter la recherche ethnographique qui décrit la dance comme articulation codée par une culture postcoloniale spécifique. Mon étude montre comment le corps colonisé produit un savoir culturel à partir de sa différence. Cette forme de savoir corporelle présente le corps colonisé en tant que sujet et non seulement objet du désir colonial. Méthodologiquement, cette dissertation rassemble des théories occidentales et autochtones de la danse. Mon étude considère aussi les théories postcoloniales du corps dansant à partir des perspectives hétérosexuelles et homosexuelles. En outre, mon étude examine les manières dont les quelles les théories contemporaines de la danse, postulées par Susan Foster et André Lepecki par exemple, peuvent être pertinentes dans le contexte postcolonial. Mon étude explore également le potentiel politique de l’érotique dans la danse à travers des représentations textuelles et cinématographiques du corps. L’introduction de ma dissertation a trois objectifs. Premièrement, elle offre un aperçu sur les théories postcoloniales du corps. Deuxièmement, elle explique les manières dans lesquelles on peut appliquer des philosophies contemporaines de la danse dans le contexte postcoloniale. Troisièmement, l’introduction analyse le rôle de la dance dans les œuvres des écrivains postcoloniales célèbres tels que Frantz Fanon, Wole Soyinka, Arundhati Roy, et Wilson Harris. Le Chapitre un remet en question les théories de l’ambiguïté et de l’insaisissabilité de la danse à partir de la théorie de l’érotique postulé par Audre Lorde. Ce chapitre examine le concept de l’érotique dans le film Dunia de Jocelyne Saab. Le Chapitre deux ouvre un dialogue entre les théories occidentales et autochtones de la danse à partir d’une étude d’un roman de Tomson Highway. Le Chapitre trois examine comment l’écrivain Trinidadien Earl Lovelace utilise la danse de carnaval comme espace culturel qui reflète l’homogénéité raciale et l’idéologie nationaliste à Trinidad et en les remettant également en question.

L'étude de la relation entre la culture organisationnelle et la violence au travail

Ce mémoire a pour objectif d’étudier la relation entre la culture organisationnelle et la violence au travail. Plus spécifiquement, les résultats permettent de déterminer comment la perception des cultures organisationnelles de type groupal, développemental, hiérarchique et rationnel de l’approche des valeurs concurrentes de Cameron et Quinn (1999) s’associent aux conflits interpersonnels et au harcèlement physique et sexuel dans les organisations. Les données proviennent de l’Étude SALVEO, menée par l’Équipe de recherche sur le travail et la santé mentale de l’Université de Montréal. À notre connaissance, aucune étude n’a étudié les perceptions des cultures organisationnelles globales des entreprises. Les études antérieures se sont intéressées à certains traits spécifiques des cultures, telles que l’acceptation, la tolérance et la banalisation de la violence, sans considérer intégralement la culture organisationnelle. Il est possible d’utiliser le modèle de Cameron et Quinn (1999) avec l’échelle de Marchand, Haines et Dextras-Gauthier (2013) pour mesurer la perception que les travailleurs se font de leur culture organisationnelle pour pouvoir les associer avec les niveaux de conflits interpersonnels et de harcèlement physique et sexuel par la suite. Les analyses multiniveaux de cette recherche ont révélé que la culture groupale s’associe à des niveaux plus bas de conflits interpersonnels et la culture développementale à des niveaux plus élevés. Bien que les résultats ne soient pas significatifs pour tous les types de culture organisationnelle, les entreprises qui adoptent des caractéristiques de la culture groupale, telles que le soutien social, la participation des travailleurs et la justice organisationnelle, semblent mieux prévenir le phénomène de la violence au travail. D’autre part, l’intégration d’un grand nombre de variables contrôles a permis de déterminer que les facteurs individuels et organisationnels les plus associés à la violence sont : le fait d’être une femme, d’être jeune, d’être syndiqué, l’effort au travail et l’injustice organisationnelle.
