to be from 2.5 to 5.5 cases per 1,000 catheter-day. the clinical impact is relevant and increases the cost of the HD Unit. Methods: The present study is the irst of 2 phases. It was conducted from January to December of 2012, and included all patients and nurses who were in the HD Unit. The prevalence of Gramnegative bacilli (GNB) and methicillin-resistant Staphylococcus aureus (MrSA) colonizing the nasal passages and the skin is described. Also, phenotypic association was sought by genus, species and sensitivities between colonizing bacterial strains and blood cultures with GNB and MRSA. Results: the study included 70 patients and 10 nurses. the prevalence of nasal colonization in patients by GNB was 9% and 6% in the pericatheter, and no nursing GNB colonization was discovered. The prevalence of MRSA nasal colonization was 19% and 6% in the pericatheter for patients and in the nurses the nasal colonization was 50% and 10% in the hands. We identiied 29 cases of primary bacteremia. The primary bacteremia rate is 1.5 per 1,000 catheter-day or 0.4 episodes per patient per year. Conclusion: We demonstrated a high prevalence of MrSA colonization in patients and nurses in the HD Unit. No relationship was found between primary bacteremia by GNB and patients and nurses’ bacteria colonization by the phenotypic comparison.

A controlled synthesis of CuO nanostructures with various morphologies were successfully achieved by presence/absence of low frequency (42 kHz) ultrasound with two different methods. The size, shape and morphology of the CuO nanostructures were tailored by altering the ultrasound, mode of addition and solvent medium. The crystalline structure and molecular vibrational modes of the prepared nanostructures were analysed through X-ray diffraction and FTIR measurement, respectively which confirmed that the nanostructures were phase pure high-quality CuO with monoclinic crystal structure. The morphological evaluation and elemental composition analysis were done using TEM and EDS attached with SEM, respectively. Furthermore, we demonstrated that the prepared CuO nanostructures could be served as an effective photocatalyst towards the degradation of methyl orange (MO) under visible light irradiation. Among the various nanostructures, the spherical shape CuO nanostructures were found to have the better catalytic activities towards MO dye degradation. The catalytic degradation performance of MO in the presence of CuO nanostructures showed the following order: spherical\nanorod \layered oval \nanoleaf \triangular \shuttles structures. The influence of loading and reusability of catalyst revealed that the efficiency of visible light assisted degradation of MO was effectively enhanced and more than 95 % of degradation was achieved after 3 cycles

This phenomenological study explored Black male law enforcement officers’ perspectives of how racial profiling shaped their decisions to explore and commit to a law enforcement career. Criterion and snow ball sampling was used to obtain the 17 participants for this study. Super’s (1990) archway model was used as the theoretical framework. The archway model “is designed to bring out the segmented but unified and developmental nature of career development, to highlight the segments, and to make their origin clear” (Super, 1990, p. 201). Interview data were analyzed using inductive, deductive, and comparative analyses. Three themes emerged from the inductive analysis of the data: (a) color and/or race does matter, (b) putting on the badge, and (c) too black to be blue and too blue to be black. The deductive analysis used a priori coding that was based on Super’s (1990) archway model. The deductive analysis revealed the participants’ career exploration was influenced by their knowledge of racial profiling and how others view them. The comparative analysis between the inductive themes and deductive findings found the theme “color and/or race does matter” was present in the relationships between and within all segments of Super’s (1990) model. The comparative analysis also revealed an expanded notion of self-concept for Black males – marginalized and/or oppressed individuals. Self-concepts, “such as self-efficacy, self-esteem, and role self-concepts, being combinations of traits ascribed to oneself” (Super, 1990, p. 202) do not completely address the self-concept of marginalized and/or oppressed individuals. The self-concept of marginalized and/or oppressed individuals is self-efficacy, self-esteem, traits ascribed to oneself expanded by their awareness of how others view them. (DuBois, 1995; Freire, 1970; Sheared, 1990; Super, 1990; Young, 1990). Ultimately, self-concept is utilized to make career and life decisions. Current human resource policies and practices do not take into consideration that negative police contact could be the result of racial profiling. Current human resource hiring guidelines penalize individuals who have had negative police contact. Therefore, racial profiling is a discriminatory act that can effectively circumvent U.S. Equal Employment Opportunities Commission laws and serve as a boundary mechanism to employment (Rocco & Gallagher, 2004).

Aims: The present study is aimed at studying the research question whether high satisfaction levels achieved through either (1) the fact that one's quality of life is truly satisfactory (i.e., stabilized life satisfaction) or through (2) adapting a more favorable perception of one's quality of life by lowering standards (i.e., resigned life satisfaction) are associated with different levels of positive affect (PA) and negative affect (NA) when compared to each other but also when compared to dissatisfied individuals. Case Report: A sample of 104 adults completed measures assessing stabilized and resigned life satisfaction, PA and NA, and global life satisfaction (i.e., no explicit consideration of differences in standards) in an online survey. Participants were not paid for participation but received feedback on results of the study if interest was expressed. Results: Stabilized life satisfaction and global life satisfaction showed highly similar correlation pattern with PA and NA. Resigned satisfaction was negatively associated with PA and positively correlated with NA. Stabilized and resigned satisfied individuals showed more favorable levels of PA and NA compared with dissatisfied individuals, but did not differ from each other with regard to their levels of PA and NA. Conclusion: Although showing a less favorable correlation pattern with PA and NA, adopting a resigned form of satisfaction (i.e., taking a more favorable view of one's quality of life by lowering individual standards) seemed to prevent individuals from experiencing the same high levels of NA like dissatisfied ones. This has not been studied in detail so far, and therefore, the present paper opens a further area of research within the context of life satisfaction.

This paper contributes to the literature on the intra-firm diffusion of innovations by investigating the factors that affect the firm’s decision to adopt and use sets of complementary innovations. We define complementary innovations those innovations whose joint use generates super additive gains, i.e. the gain from the joint adoption is higher than the sum of the gains derived from the adoption of each innovation in isolation. From a theoretical perspective, we present a simple decision model, whereby the firm decides ‘whether’ and ‘how much’ to invest in each of the innovations under investigation based upon the expected profit gain from each possible combination of adoption and use. The model shows how the extent of complementarity among the innovations can affect the firm’s profit gains and therefore the likelihood that the firm will adopt these innovations jointly, rather than individually. From an empirical perspective, we focus on four sets of management practices, namely operating (OMP), monitoring (MMP), targets (TMP) and incentives (IMP) management practices. We show that these sets of practices, although to a different extent, are complementary to each other. Then, we construct a synthetic indicator of the depth of their use. The resulting intra-firm index is built to reflect not only the number of practices adopted but also the depth of their individual use and the extent of their complementarity. The empirical testing of the decision model is carried out using the evidence from the adoption behaviour of a sample of 1,238 UK establishments present in the 2004 Workplace Employment Relations Survey (WERS). Our empirical results show that the intra-firm profitability based model is a good model in that it can explain more of the variability of joint adoption than models based upon the variability of adoption and use of individual practices. We also investigate whether a number of firm specific and market characteristics by affecting the size of the gains (which the joint adoption of innovations can generate) may drive the intensity of use of the four innovations. We find that establishment size, whether foreign owned, whether exposed to an international market and the degree of homogeneity of the final product are important determinants of the intensity of the joint adoption of the four innovations. Most importantly, our results point out that the factors that the economics of innovation literature has been showing to affect the intensity of use of a technological innovation do also affect the intensity of use of sets of innovative management practices. However, they can explain only a small part of the diversity of their joint adoption use by the firms in the sample.

A key concern organisations face is how to incorporate Internet tools into their marketing communications mix. Where and how should companies invest their human, technological and financial resources? This paper explores a subset of this problem, online complaining and electronic customer service. It applies diffusion of innovation as a theoretical framework to investigate organisational implementation of email technology and explain the outcome of annual customer service surveys in 2001, 2002 and 2003. The results add to the small body of research on electronic service recovery by extending diffusion of innovations to email service recovery and underscoring the importance of adoption phases, particularly for SMEs. Larger companies provide more channels for submitting complaints, which represents an early phase of adoption. There was little difference in how large and small companies respond to online complaints, a later phase of adoption.

It is argued widely that the academy today is in the process of significant change—in the institutional assumptions of what constitutes the university and the construction of knowledge and in its relations with the city and the world. This article addresses the evolution of the modern university in the context of the discourses of contemporary globalizing institutions. Further, it empirically assesses the organizational priorities of U.S. research universities in light of the application of these discourses to their objectives and practices, finding that they are playing a key role in the formal representation of the institutional direction, goals, and values of American higher education.

Au-delà des variables climatiques, d’autres facteurs non climatiques sont à considérer dans l’analyse de la vulnérabilité et de l’adaptation au changement et variabilité climatiques. Cette mutation de paradigme place l’agent humain au centre du processus d’adaptation au changement climatique, notamment en ce qui concerne le rôle des réseaux sociaux dans la transmission des nouvelles idées. Dans le domaine de l’agriculture, le recours aux innovations est prôné comme stratégie d’adaptation. L’élaboration et l’appropriation de ces stratégies d’adaptation peuvent être considérées comme des processus d’innovation qui dépendent autant du contexte social et culturel d’un territoire, de sa dynamique, ainsi que de la stratégie elle-même. Aussi, l’appropriation et la diffusion d’une innovation s’opèrent à partir d’un processus décisionnel à l’échelle de l’exploitation agricole, qui à son tour, demande une compréhension des multiples forces et facteurs externes et internes à l’exploitation et les multiples objectifs de l’exploitant. Ainsi, la compréhension de l’environnement décisionnel de l’exploitant agricole à l’échelle de la ferme est vitale, car elle est un préalable incontournable au succès et à la durabilité de toute politique d’adaptation de l’agriculture. Or, dans un secteur comme l’agriculture, il est reconnu que les réseaux sociaux par exemple, jouent un rôle crucial dans l’adaptation notamment, par le truchement de la diffusion des innovations. Aussi, l’objectif de cette recherche est d’analyser comment les exploitants agricoles s’approprient et conçoivent les stratégies d’adaptation au changement et à la variabilité climatiques dans une perspective de diffusion des innovations. Cette étude a été menée en Montérégie-Ouest, région du sud-ouest du Québec, connue pour être l’une des plus importantes régions agricoles du Québec, en raison des facteurs climatiques et édaphiques favorables. Cinquante-deux entrevues ont été conduites auprès de différents intervenants à l’agriculture aux niveaux local et régional. L’approche grounded theory est utilisée pour analyser, et explorer les contours de l’environnement décisionnel des exploitants agricoles relativement à l’utilisation des innovations comme stratégie d’adaptation. Les résultats montrent que les innovations ne sont pas implicitement conçues pour faire face aux changements et à la variabilité climatiques même si l’évolution du climat influence leur émergence, la décision d’innover étant largement déterminée par des considérations économiques. D’autre part, l‘étude montre aussi une faiblesse du capital sociale au sein des exploitants agricoles liée à l’influence prépondérante exercée par le secteur privé, principal fournisseur de matériels et intrants agricoles. L’influence du secteur privé se traduit par la domination des considérations économiques sur les préoccupations écologiques et la tentation du profit à court terme de la part des exploitants agricoles, ce qui pose la problématique de la soutenabilité des interventions en matière d’adaptation de l’agriculture québécoise. L’étude fait ressortir aussi la complémentarité entre les réseaux sociaux informels et les structures formelles de soutien à l’adaptation, de même que la nécessité d’établir des partenariats. De plus, l’étude place l’adaptation de l’agriculture québécoise dans une perspective d’adaptation privée dont la réussite repose sur une « socialisation » des innovations, laquelle devrait conduire à l’émergence de processus institutionnels formels et informels. La mise en place de ce type de partenariat peut grandement contribuer à améliorer le processus d’adaptation à l’échelle locale.

In this study, we review the literature on the creation and diffusion of innovation in the private sectors (industry and services) in developing countries. In particular, we collect evidence on what are the barriers to innovation creation and diffusion and the channels of innovation diffusion to and within developing countries. We find that innovation in developing countries is about creation or adoption of new ideas and technologies; but the capacity for innovation is embedded in and constituted by dynamics between geographical, socio-economic, political and legal subsystems. We contextualize the findings from the review in the current theoretical framework of diffusion of innovations, and we emphasize how the institutional context typical of developing countries impacts the diffusion itself.

Despite several examples of deployed agent systems, there remain barriers to the large-scale adoption of agent technologies. In order to understand these barriers, this paper considers aspects of marketing theory which deal with diffusion of innovations and their relevance to the agents domain and the current state of diffusion of agent technologies. In particular, the paper examines the role of standards in the adoption of new technologies, describes the agent standards landscape, and compares the development and diffusion of agent technologies with that of object-oriented programming. The paper also reports on a simulation model developed in order to consider different trajectories for the adoption of agent technologies, with trajectories based on various assumptions regarding industry structure and the existence of competing technology standards. We present details of the simulation model and its assumptions, along with the results of the simulation exercises.
