Abstract:
Using the model and quantitative parameters of contrast-enhanced ultrasound (CEUS) to assess the severity of secondary hyperparathyroidism (SHPT) was proposed. 42 SHPT patients who underwent CEUS examination were divided into three groups, light, moderate, and heavy as per parathyroid hormone (PTH). The process of CEUS was divided into two phases, wash-in phase and wash-out phase. The three groups were analyzed with their enhancing model in the two phases. The quantitative parameters of CEUS such as Arrival Time (AT), Time to Peak (TTP), Mean Transit Time (MTT), and Maximum Intensity (IMAX) were measured by time-intensity curve (TIC) and compared among the three groups. The enhancing model of light SHPT, moderate SHPT, and heavy SHPT showed statistical significance in wash-in phase and wash-out phase (P<0.05). No difference was observed in AT and TTP among the three groups (P>0.05) while MTT and IMAX showed statistical significance (P<0.05). The CEUS of light SHPT was characterized by “slow-in, fast-out, and lower-enhancement” with short enhancement time; the CEUS of moderate SHPT was characterized by “fast-in, fast-out, and higher-enhancement” with slightly long enhancement time; the CEUS of heavy SHPT was characterized by “fast-in, slow-out, and higher-enhancement” with long enhancement time. Therefore, the model and quantitative parameters of CEUS can be benefit for the assessment of the severity of SHPT.

Abstract:
Background: Intraplaque neovascularization and vasa vasorum (VV) proliferation contribute in the progression and rupture of atherosclerotic lesions. Contrast Enhanced Ultrasonography (CEUS) has been reported to attain data regarding intraplaque neovessels and VV. However, whether the detection of microbubbles by CEUS within atherosclerotic plaques truly represents microvessels is a point of concern. We aimed to evaluate stable and unstable carotid artery plaque (CAP) VV pattern by CEUS and its correlation with histology and immunochemistry. Patients and methods: Patients with CAP scheduled for plaque endarterectomy were enrolled. CAP was initially identified by conventional ultrasonography and subsequently CEUS (harmonic ultrasound imaging with simultaneous intravenous contrast agent injection) was performed. The recorded image loops were evaluated by a semi-automated method. Plaque specimens were excised and underwent histological and immunochemical (for CD34, Vascular Endothelial Growth Factor, CD68 and CD3 antibodies) analysis. Results: Fourteen patients (67.6 ± 10.2 years, 10 males) with a 86.9 ± 11.5 % degree of carotid artery stenosis were evaluated. Histology showed that half of the plaques were unstable. Enhancement of plaque brightness on CEUS was significant for both stable and unstable plaque subgroups (p = 0.018 for both). Immunochemistry showed that microvessels, as assessed by CD34 antibody, were more dense in unstable vs. stable plaques (36.6 ± 17.4 vs. 13.0 ± 7.2 respectively, p = 0.002). However, correlation between plaque brigthness enhancement on CEUS and microvessel density was significant only for stable (r = 0.800, p = 0.031) plaques. Conclusions: The identification of brightness enhacement during CEUS in carotid atherosclerotic plaques may not always reflect the presence of VV.

Abstract:
Background and Objectives: preoperative differentiation of enlarged parathyroid glands may be challenging in conventional B-mode ultrasound. The aim of our study was to analyse qualitative and quantitative characteristics of parathyroid gland lesions, using multiparametric ultrasound protocol—B-mode, Colour Doppler (CD), and contrast-enhanced ultrasound (CEUS)—and to evaluate correlation with morphology in patients with hyperparathyroidism (HPT). Materials and Methods: consecutive 75 patients with 88 parathyroid lesions and biochemically confirmed HPT prior to parathyroidectomy were enrolled in the prospective study. B-mode ultrasound, CD, and CEUS were performed with the subsequent qualitative and quantitative evaluation of acquired data. We used 1 mL or 2 mL of intravenous ultrasound contrast agent during the CEUS examination. Correlation with post-surgical morphology was evaluated. Results: seventy parathyroid adenomas were hypoechoic and well contoured with increased central echogenicity (44.3%), peripheral-central vascularization (47%), and polar feeding vessel (100%). Twelve hyperplasias presented with similar ultrasound appearance and were smaller in volume (p = 0.036). Hyperplasias had a tendency for homogenous, marked intense enhancement vs. peripherally enhanced adenomas with central wash-out in CEUS after quantitative analysis. No significant difference was observed in contrasting dynamics, regardless of contrast media volume use (1 mL vs. 2 mL). We achieved 90.9% sensitivity and 72.7% specificity, 93% positive predictive value (PPV), 87.3% negative predictive value (NPV), and 87.3% accuracy in the differentiation of parathyroid lesions prior to post-processing. In a quantitative lesion analysis, our sensitivity increased up to 98%, specificity 80%, PPV 98%, and NPV 80% with an accuracy of 96.4%. Conclusions: CEUS of parathyroid lesions shows potential in the differentiation of adenoma from hyperplasia, regardless of the amount of contrast media injected. The quantitative analysis improved the sensitivity and specificity of differentiation between parathyroid lesions. Hyperplasia was characterized by homogeneous enhancement, fast uptake, and homogeneous wash-out appearance; adenoma—by peripheral uptake, central wash-out, and reduced hemodynamics. The use of CEUS quantification methods are advised to improve the ultrasound diagnostic role in suspected parathyroid lesions.

Abstract:
In the past thirty years, breast cancer in women has continued to rise. The age of onset for women has become lower. Contrast-enhanced ultrasound (CEUS) can clearly show the blood perfusion and neovascularization of breast masses. Elastography provides information on the stiffness of tissues. The combination of them shows a good advantage in the various early diagnosis of breast cancer. The combined electrograph can distinguish benign and malignant apocrine breast tumors. The shear wave electrograph (SWE) combined with CEUS has the strongest consistency in the diagnosis and pathology of breast benign tumors. When they were diagnosed separately, it was found that SWE has higher diagnostic value than CEUS; the quantitative diagnosis of SWE is slightly higher than the qualitative diagnosis, and the qualitative diagnosis of CEUS is higher than the quantitative diagnosis. Both SWE and CEUS are valuable in the diagnosis of benign and malignant apocrine breast tumor when combined treatment is made.

Abstract:
Background Microvascularization of the bowel wall can be visualized and quantified non-invasively by software-assisted analysis of derived time-intensity curves. Purpose To perform software-based quantification of bowel wall perfusion using quantitative contrast-enhanced ultrasound (CEUS) according to clinical response in patients with inflammatory bowel disease treated with vedolizumab. Material and Methods In a prospective study, in 18 out of 34 patients, high-frequency ultrasound of bowel wall thickness using color Doppler flow combined with CEUS was performed at baseline and after 14 weeks of treatment with vedolizumab. Clinical activity scores at week 14 were used to differentiate between responders and non-responders. CEUS parameters were calculated by software analysis of the video loops. Results Nine of 18 patients (11 with Crohn’s disease and seven with ulcerative colitis) showed response to treatment with vedolizumab. Overall, the responder group showed a significant decrease in the semi-quantitative color Doppler vascularization score. Amplitude-derived CEUS parameters of mural microvascularization such as peak enhancement or wash-in rate decreased in responders, in contrast with non-responders. Time-derived parameters remained stable or increased during treatment in all patients. Conclusion Analysis of bowel microvascularization by CEUS shows statistically significant changes in the wash-in-rate related to response of vedolizumab therapy.

Abstract:
SummaryObjective of our study is qualitative and quantitative comparison of contrast enhanced ultrasound (CEUS) and 18F-FDG PETCT in monitoring hepatic alveolar echinococcosis (HAE). Parasitic liver lesions were examined regarding number, size, morphology, vascularization and metabolic activity. Patients, methods: 36 patients with medicallytreated HAE were included in this prospective clinical study. Abdominal ultrasound and CEUS were carried out using ultrasound contrast amplifier SonoVue®. As part of monitoring, patients were examined by 18F-FDG-PET-CT. Quantitative analysis of CEUS was performed using the Software Vue- Box™ Quantification Toolbox. Maximum contrast enhancement in lesions peak enhancement (PE) was used as parameter. For quantification of 18F-FDG PET-CT, maximum Standardized Uptake Value (SUVmax) of lesions was specified and statistically compared with PE. Results: 18F-FDG uptake in parasitic liver lesions was diagnosed by 18F-FDG PET-CT in 32 of 36 patients. Vascularization of liver lesions was detected by CEUS in 22 of 32 FDG-positive patients with sensitivity of 69% and specificity of 100%. Mean maximum diameter of lesions was 69.5mm in CEUS and 63.7mm in B-scan ultrasound (p < 0.0001). No significant correlation was found between SUVmax and PE (p = 0.8879). Conclusion: In comparison to FDG PET-CT, the gold standard for detecting viable lesions by depicting metabolism, CEUS detects viable lesions with high specificity and moderate sensitivity by showing vascularization. CEUS must be regarded as an important tool in monitoring HAE. Dimensions of parasitic lesions are displayed more precisely through CEUS than in B-scan. With currently available methods, CEUS quantification has no benefit in monitoring HAE lesions in daily clinical practice.

Abstract:
Objective: The preoperative diagnostical differentiation of parotid gland tumor (PGT) is not always simple due to several different entities. B-mode-ultrasound (US) remains the imaging modality of choice, while histopathology serves as the gold standard for finalizing the diagnosis. We aimed to evaluate the use of multiparametric US (mpUS) in the assessment of PGT. Methods: We included 97 PGTs from 96 patients. A standardized mpUS protocol using B-mode-US, shear-wave elastography (SWE), and standardized contrast-enhanced ultrasound (CEUS) was performed prior to surgical intervention. SWE was assessed by real-time measurement conducting a minimum of five measurements, while quantitative CEUS parameters were assessed with a post-processing perfusion software. Results: SWE allowed differentiation between benign PGT (Warthin’s Tumor (WT) paired with lymph nodes (LN) and pleomorphic adenoma (PA)), and WT and LN were softer compared to PA. WT showed lower velocities than squamous cell carcinoma (SCC): the most common malignant PGT. CEUS parameters showed significant group differences between WT and PA, WT and malignant lesions, WT and SCC, WT paired with LN versus PA, and WT paired with LN versus SCC. Conclusion: MpUS seems to be beneficial in the assessment of PGT characterization, with benign PGT appearing to be softer in SWE than tumors with malignant tendencies. The quantitative CEUS parameter shows higher perfusion in WT than in PA, and malignant PGTs are less vascularized than WTs.

Abstract This article reviews the application of contrast-enhanced ultrasound (CEUS) in gauging renal microvascular perfusion in diverse renal diseases. The unique nature of the contrast agents used in CEUS provides real-time and quantitative imaging of the vasculature. In addition to the traditional use of CEUS for evaluation of kidney masses, it also emerges as a safe and effective imaging approach to assess microvascular perfusion in diffuse renal lesions, non-invasively. Although the precise CEUS parameters that may best predict disease still warrant systematic evaluation, animal models and limited clinical trials in humans raise hopes that CEUS could outcompete competing modalities as a first-line tool for assessing renal perfusion non-invasively, even in ailments such as acute kidney injury and chronic kidney disease.

BackgroundContrast-enhanced ultrasonography (CEUS) features of primary hepatobiliary neoplasms have been reported in dogs but no information is available in cats.MethodsQualitative and quantitative features of bile duct adenomas (BDAs, n=20), bile duct carcinomas (BDCs, n=16), and hepatocellular carcinomas (HCCs, n=8) are described in 44 cats.ResultsThere was an overlap in CEUS qualitative features between different histotypes, both in wash-in and wash-out phases. Distinction between different neoplasms based only on the CEUS qualitative features was not possible. At peak of enhancement, the BDAs, BDCs and HCCs showed a large range of echogenicities, from hypoenhancement to hyperenhancement, in comparison to the liver parenchyma. Eight of 20 BDAs showed inhomogeneous hyperenhancement during wash-in, which is a feature reported as typical of malignant lesions in dogs. BDC had a significantly faster wash-in compared with both BDA and HCC but the diagnostic accuracy of all the included quantitative variables was only moderate. No significant differences in the wash-out quantitative features of BDA and BDC were evident.ConclusionThere is poor evidence that CEUS may be used to distinguish between different primary hepatobiliary neoplasms in cats.

Abstract:
In recent years, due to the influence of living habits and smoking, the number of lung cancer patients worldwide has increased year by year, and it has gradually developed into one of the common diseases endangering human life. CEUS can observe the lesion and realize the rapid identification of the location of the active area of the lesion. CEUS is the abbreviation of contrast-enhanced ultrasound technology. Contrast-enhanced ultrasound technology is to inject ultrasound contrast agent through a peripheral vein to perform ultrasound exploration to observe the enhancement of the internal nodules. Compared with color ultrasound, it can diagnose more accurately and improve the inspection effect. At present, this technology is used for the diagnosis of many types of space-occupying lesions, but it is rarely used for the diagnosis of lung lesions. The purpose of this study is to explore the role of CEUS quantitative parameters combined with lung biopsy in the assessment of benign and malignant peripheral lung diseases. Based on the relevant theoretical basis of CEUS and lung biopsy, 158 patients with peripheral lung disease were selected as experimental subjects, and they were divided into experimental group and control group for comparative experiments. Experiments proved the effectiveness of CEUS quantitative parameters combined with lung biopsy methods. The experimental results showed that, compared with the benign group, the time-intensity curve, the rise time, and the peak time of the malignant lesions were significantly prolonged. In addition, CEUS combined with the quantitative parameters of lung biopsy can effectively distinguish the activity of lung lesions and the site of necrosis and promote the effective increase of the positive rate of lung biopsy.

Abstract:
Diseases of the urinary system are regularly encountered in daily veterinary practice. The development of increasingly efficient diagnostic tools is crucial to meet the high-quality requirements of contemporary professional standards. This project had many purposes, aiming to describe pioneering methods, protocols and diagnosis related to imaging of ureters and urinary bladder, chosen as they represent daily diagnostic challenges in daily routine practice. This project consisted of three papers: the first paper is a prospective pilot project concerning quantitative CEUS exam applied to distinguish neoplastic and non-neoplastic lesions of the urinary bladder in small animals; the second paper is a multicentric retrospective observational project describing the CT appearance of a novel CVC congenital malformation; the third paper is a retrospective study conducted on canine healthy patients, aimed at assessing the visibility of the ureters on high field MR on T1 and T2 sequences avoiding the use of paramagnetic contrast agents. The results of this project allowed to obtain objectifiable parameters for the distinction of neoplastic and non-neoplastic lesions of urinary bladder using quantitative CEUS; we also described the CT appearance of the transcaval ureter, a malfomaration of the CVC never described in veterinary medicine; finally, we described the feasibility of evaluation of normal ureters through high-field MR on T2-weighted sequences, in healthy canine patients. In conclusion, this project allowed to describe new diseases that could affect urinary tract function and contributes to the development of new methods and protocols with the potential to reduce the invasiveness of certain diagnostic procedures related to the urinary tract.

This study examined the perceptions of celebrity CEOs potentially transitioning to political candidates. Using Carly Fiorina's campaign for Senator of California, this study identified how young voters perceive celebrity CEOs as politicians, their identification of celebrity CEOs, and the evaluations of CEOs and their companies. Results indicate a more favorable evaluation of Fiorina resulted in a more favorable reaction to Hewlett- Packard. Results also confirm the use of media messages to prime young voters about political candidates. Finally, political party affiliation was found to significantly influence the findings of this study while gender and political cynicism did not. Theoretical implications and areas of future research in celebrity and politics are discussed.

Abstract:
The effects of cranial electrotherapy stimulation (CES) on human EEG and brain current density were evaluated by quantitative electroencephalography (qEEG) and low resolution brain electromagnetic tomography (LORETA). A total of 72 research subjects were provided with a single session of CES, 38 were provided with 0.5 Hz CES while 34 were provided with 100 Hz CES. The qEEG paired t-tests revealed that in both frequencies of CES there was a significant (.05) increase in alpha relative power with concomitant decreases in delta and beta relative power. The 0.5 Hz CES decreased a wider frequency range of delta activity, while the 100 Hz CES decreased a wider frequency range of beta activity; suggesting some difference may exist in the EEG response to different frequencies of CES. The changes found in qEEG relative power were consistent with the affective and cognitive effects of CES reported in the literature, such as increased relaxation and decreased anxiety. Statistically significant changes for qEEG values other than relative power, such as coherence, amplitude asymmetry, phase lag and power ratios were also found. The LORETA paired t-tests found statistically significant (.05) increases in cortical and subcortical theta and alpha frequency current density with concomitant decreases in delta and beta current density. The effects of CES on current density varied by frequency, but did not show a differential in response based on proximity to the contacts, or structures within the brain. Statistically significant changes in current density were found in all 2394 gray matter voxels represented by LORETA, indicating a whole brain response to the CES stimulus. The qEEG and LORETA findings revealed that a single 20-minute session of CES does have a significant effect on the cortical and subcortical activity of the human brain resulting in activity consistent with decreased anxiety and increased relaxation.

Abstract:
While the number of African American women filling executive level positions in Fortune 500 companies in America has improved, there is still a need for significant improvements in increasing their access to corporate chief executive officer (CEO) positions. African American women occupy only 11.7% of the board seats, and their representation as CEOs has steadily declined. Throughout the history of Fortune 500 companies, there have been only 14 African American men with CEO titles. As of January 2017, there are no African American women CEOs. The purpose of this phenomenological study was to examine the lived experiences and perceptions of 15 African American women who aspire to be chief executive officers in corporate America. The experiences and perceptions of these women were examined to understand why there is a limited number of African American women CEOs despite their increase in executive level roles. The responses from 15 African American revealed that the increased numbers of these women in the executive leadership level resulted from diversity initiatives that made it possible for these women to return to school, and provided a context in which organizational leaders could recognize their talent. The organizations' use of diversity initiatives contributed to practices that legally allow them to minimize the number of minorities they hire at the executive level. The theoretical framework included elements from critical theory, critical race theory, and black feminist theory. The increased representation of these women at the executive level contributes to positive social change because the information adds to the existing literature on the lack of African American women CEOs in corporate America and may provide knowledge that will guide other women pursuing this role.

Réalisée dans le cadre d’un contrat CIFRE, cette thèse étudie la construction, l’appropriation et les effets de la politique d’égalité professionnelle entre les femmes et les hommes chez Orange. Mobilisant la perspective appropriative des dispositifs de gestion enrichie par le concept de logiques institutionnelles, ce travail repose sur un matériau riche et varié : entretiens, données RH, séquences d’observation, documents internes, notamment. Nous montrons que la coexistence de plusieurs conceptions de l’égalité professionnelle au sein de l’entreprise structure fortement l’application de la politique au niveau local, mais également sa construction, qu’il s’agisse de l’accord d’entreprise ou de la politique non négociée. L’analyse conjointe de l’application de la politique et de ses effets, permise par la combinaison de matériaux et de méthodes qualitatifs et quantitatifs, nous donne de plus l’opportunité de comprendre les effets quantifiables (ou l’absence d’effets quantifiables) d’une mesure à l’aune de la manière dont elle est appliquée au niveau local. Nous mettons enfin en exergue les spécificités de la négociation sur l’égalité professionnelle par rapport à d’autres négociations, dues notamment à la transversalité de l’égalité professionnelle à de nombreux processus RH ; et nous soulignons l’importance de la coexistence et de l’articulation de l’accord d’entreprise et de la politique non négociée sur l’égalité professionnelle
This thesis, written while working under a CIFRE contract, studies the construction, the implementation and the effects of the gender equality policy at Orange. Using the appropriative perspective of management tools enriched by the concept of institutional logics, this work is based on various data, in particular: interviews, HR data, observations, internal documents. We show that the coexistence of various conceptions of gender equality within the company strongly affects the implementation of the gender equality policy within the entities, but also its construction, for both the collective bargaining agreement and the non-negotiated policy. The joint analysis of the implementation and of the effects of the policy, made possible by a mixed-method design, allows us to understand the quantifiable effects (or the absence of quantifiable effects) of a measure according to the way it is implemented within the entities. We underline the specificities of the collective bargaining about gender equality, notably due to the fact that gender equality cuts across various HR processes. Finally, we show the importance of the coexistence and articulation of the collective bargaining agreement and non-negotiated gender equality policy

Full text
Abstract:
In general, doctoral programs in counselor education and supervision (CES) have low minority enrollments. Faculty members in clinical mental health counseling (CMHC) master's degree in science (MS) programs primarily come from CES doctoral programs; therefore, faculty members do not generally reflect the diversity of the MS student population. Using the theory of planned behavior and the bioecological model, the purpose of this research was to determine the extent to which age, gender, faculty support, income, level of parents' or primary caregivers' education, and the Council for Accreditation of Counseling and Related Educational Programs (CACREP) accreditation status predict White and racial minority MS students' decisions to pursue CES doctoral studies and to see if there were differences between the factors for White and minority students. A demographic questionnaire and the Perceived Faculty Support Scale were used to measure the variables through multiple regression, Spearman rho, t tests, chi square, and the Mann Whitney U analyses. No variables were significantly predictive for either student groups. Because there were no significant differences between White and minority MS students choosing CES programs, an approach to increase the number of minority faculty members in CMCHC MS programs as a way of promoting positive social change might be for program administrators and faculty to recruit more minority students into MS programs in order to expand the pool of potential CES students. An additional recommendation is for current CES faculty to encourage more minority students who do choose CES doctoral programs to pursue faculty positions after graduation.

Ce protocole a été appliqué au dosage des ARNt-Q modifiés présents dans le foie de différents animaux, dans des cellules normales ou néoplastiques de foie de rat en culture, ainsi que dans des tumeurs humaines du tractus génital féminin. Nos résultats montrent que les ARNt-Q des foies de mammifères adultes sont totalement modifiés en queuosines. Par contre, une diminution du taux de modification des ARNt-Q est observée dans les foies de rats nouveau-nés et dans les foies de poulets élevés en batterie. Une hypomodification importante des ARNt-Q est également constatée dans des cellules d'hépatome de rat. Les tumeurs humaines du tractus génital féminin présentent, elles aussi, une diminution du contenu en queuosines de leur ARNt. Dans toutes ces études, nous avons pu démontrer que les ARNt asp sont toujours les moins affectés par l'hypomodification. Ces observations montrent que l'hypomodification des ARNt-Q est la conséquence, soit d'une diminution de l'apport en queuine, soit d'un dysfonctionnement métabolique spécifique aux cellules tumorales. Les mécanismes impliqués dans l'hypomodification des ARNt-Q de tissus tumoraux et dans cette sorte de "protection" constante des ARNt asp modifiés restent à élucider.

Abstract:
We illustrate the central role the bonobo plays in testing evolutionary hypotheses regarding ape minds (including our own). The importance of bonobos has become apparent only recently with sustained fieldwork at multiple sites in the Congo Basin as well as the first direct quantitative comparisons between bonobos, chimpanzees and humans. This recent work has revealed a number of traits in which bonobos and chimpanzees are more similar to humans than they are to each other. This means that bonobos are crucial to determining the evolutionary processes by which cognitive traits evolved in our own lineage. Based on the evidence within, it becomes clear that one can no longer know chimpanzees or humans without also knowing bonobos. We argue this makes investing in bonobo research and improved protection for bonobos in captivity and the wild an even higher priority. Nous illustrons le rôle central joué par le bonobo pour tester les hypothèses relatives à l’évolution de l’esprit des grands singes (y compris le nôtre). L’importance des bonobos n’est apparue que récemment grâce à un travail de terrain soutenu sur de multiples sites dans le bassin du Congo ainsi qu’aux premières comparaisons quantitatives directes entre les bonobos, les chimpanzés et les humains. Ces récents travaux ont révélé un certain nombre de caractéristiques pour lesquelles les bonobos et les chimpanzés présentent plus de similarités avec les humains que l’un envers l’autre. Cela signifie que les bonobos sont essentiels pour déterminer les processus d’évolution par lesquels les caractéristiques cognitives ont évolué dans notre propre lignée. Sur la base des preuves contenues dans ce document, il devient clair que l’on ne peut plus connaître les chimpanzés ou les humains sans connaître les bonobos. Cela rend donc d’autant plus primordiaux l’investissement dans la recherche sur les bonobos et l’amélioration de la protection des bonobos en captivité comme à l’état sauvage.

Abstract:
Social science research on environment and activism with a cross- or transnational scope (REACTS) is described as a consolidated but confused, stagnant field of scholarship, one which has yet to surpass the comparable state of international studies at large. Previous reviews of the literature in this growing and interdisciplinary research domain have gone so far as so divide it into either its cross-national or its transnational branch, respectively associated with cross-national and environmental social science (CESS), or transnational and environmental social science (TESS). As evidence of stagnancy, once the CESS and TESS branches of REACTS are combined, changes in the cross-national research agenda have been merely the reverse of the transnational one. From 1969–75, REACTS literature covered the themes of population, catastrophic limits to growth, interstate conferences and organizations, North–South relations, survivalist/lifeboat ethics, resource and land conservation, and the social movement organization/non-governmental organization/"third sector." From 1977–91, the issues covered shifted to emphasize violence/conflict, counter environmentalist backlash, seal hunting, whaling, rural energy (improved bioenergy cookstoves), and possibly baby foods, though the earlier concerns with population, (nature) conservation, interstate conferences and survivalist/lifeboat ethics continued. The resistance literature was considerably consolidated and there was a quantitative change in the attention that environmental activism itself received within the pre-existing orientations. In the post-1992 era, the thematic array of transnational REACTS expanded even further as additional issues made it to the agenda in international and environmental studies.

Abstract:
AbstractProvision of safe drinking water (DW) is one of the major requisites for human health, related to four Sustainable Development Goals (SDGs) of the United Nation 2030 Agenda: SDGs 3 (Good health), 6 (Clean water and sanitation), 11 (Sustainable cities) and 12 (Responsible production and consumption). However, this is hindered by the presence, especially in highly-anthropized contexts, of contaminants of emerging concern (CECs) in DW, that may pose a risk for human health. The present study aims at developing a holistic framework to support both (i) decision-makers for CECs prioritization in DW regulation and (ii) water utilities for the selection of appropriate monitoring and treatment interventions for the optimization of DW supply system. In detail, a quantitative chemical risk assessment (QCRA), including uncertainties related to both exposure and hazard assessments, was developed. Then, it was combined with testing and modeling of CECs fate in treatment processes and in distribution network, obtaining a robust tool to achieve the above-mentioned SDGs. Graphical Abstract

Abstract:
Num ambiente cada vez mais concorrencial, as organizações precisam de conhecer o perfil dos seus clientes e estar atentas às mudanças do meio envolvente e ao comportamento dos concorrentes, consumidores e clientes. Para isso, precisam de obter dados através de várias fontes de informação que, depois de tratados de forma sistemática, geram conhecimento sobre o mercado. O desenvolvimento de um Sistema de Marketing Intelligence (SMI) permite recolher, organizar, armazenar, processar dados e distribuir informações pertinentes e atempadas aos gestores e equipa de vendas da empresa. Na maior parte das situações as empresas dispõem de programas de gestão comercial (Customer Relationship Management – CRM, por exemplo) que os ajudam na gestão da informação dos clientes da empresa. No entanto, este capítulo vai mais lá disso, pois contempla a conceção de um sistema que, para além da gestão da informação da empresa e dos seus clientes, engloba a análise de informação sobre o meio envolvente, a concorrência e os consumidores. Para isso, são explicadas as principais técnicas de pesquisa que viabilizam a obtenção de informação sistemática e/ ou pontual para ajudar no processo de tomada de decisões de nível estratégico e tático. O capítulo começa com a descrição dos elementos que compõem um SMI de uma empresa fornecendo o conceito e analisando detalhadamente os componentes desse sistema (meio envolvente, empresa, clientes, concorrentes e consumidor). Na secção dois são apresentadas as principais técnicas de pesquisa (estudos documentais, qualitativos e quantitativos), seguindo-se, na secção seguinte, o cruzamento entre os elementos do SMI com as técnicas de pesquisa. O capítulo encerra com o esboço de um SMI.

Abstract:
The approach is taking into account the fact that Entrepreneurs and, broadly speaking, the CEOs are ubiquitous, a characteristic of the market that can never be absent. It is considered a modern factor of production, along with the classic ones, as land, labor, and capital. For our purpose, we consider a factor of production any resource needed for the creation of an economic good, or service, in order to make, finally, profit. In this respect, both owners/entrepreneurs and CEOs are considered a decisive factor of production because, by their skills, knowledge, and abilities, they create and add value to the firm/corporation. We used the quantitative research, consisting in the study of the practices and experiences of the firms, ownership and management in order to synthesize that the Entrepreneurship and CEOs’ existence are intrinsic and vital to economic businesses. The results prove that it is necessary combining in original and efficient manner the skills and knowledge of the Entrepreneur and CEOs to get profit and the sustainability on the specific market. These challenges demand quick and appropriate answers from entities. Therefore, the theory of the firm, the theory of entrepreneurship has to be developed based on these new realities and folded on the main form of organization.

Abstract:
This chapter provides the reader with a helicopter view of a quantitative value-based framework. A key argument in this book is that volatility is always present. Uncertainty means that today's successful CEOs and their executive teams need to be able to act simultaneously as strategists—that is, designers of corporate strategy—and opportunists—with the ability to grasp opportunities that meet their value criteria as they arise. In essence, this requires the setting of clear strategic goals, but—given the reality of uncertainty—also being willing to revise intended decisions, seeking to continually maximize the organization's options to appropriate value. While uncertainty generally deters investment, executives who reframe their roles as strategic opportunists can actually benefit from uncertainty.

Abstract:
The use of LNG propulsion in ships has significant environmental benefits but also creates challenges in handling the LNG. Due to the safety regulations, the maintenance of the LNG ship systems is essential and requires a high degree of reliability and accuracy. Here, digital assistance systems, e.g., based on Augment-ed Reality (AR) technology, can support the maintenance and service purposes of LNG ship systems by displaying additional information directly on the objects to be serviced. Thus, this paper deals with the development and evaluation of a digital assistance system using AR technology. The developed assistance system based on an Android smartphone enables users to access maintenance instruc-tions and manuals, simplifies spare parts' ordering, and supports the work pro-cess step by step through context-sensitive virtualizations. Its evaluation was conducted as a combined quantitative and qualitative user study. Overall, the assistance system offers promising potentials for reducing workload and improv-ing processes.

L’étude montre l’influence du système éducatif chinois sur les études et les comportements des étudiants chinois en France. Elle permet aussi de voir l’importance de la motivation et de l’objectif du séjour dans le choix des activités à l’étranger. Enfin, cette étude pourrait inspirer les enseignants de FLE à l’égard de la formation en compétences interculturelles des étudiants, notamment de nationalité chinoise.

Abstract:
Notre travail s’articule autour du thème de l’eau dans Pierre et Jean et Mont-Oriol de Guy de Maupassant. En effet, ces deux œuvres romanesques regorgent d’eau dans toutes ses formes. Dans Pierre et Jean, le lexique de la mer est fort abondant. Le thème de la mer revient sans cesse dans le roman. Il y apparaît en ouverture et en conclusion, évoquant longuement les bateaux et la pêche. Dans Mont-Oriol, l’élément aquatique détermine son espace romanesque et constitue à lui seul le cadre du roman. Il est présent sous plusieurs aspects : eau, source, lac, station, ruisseau. Les images de l’eau dans ces deux œuvres romanesques reflètent l’amour de l’auteur normand pour cet élément naturel. Afin d’analyser ce jaillissement du lexique de l’eau dans ces deux œuvres, nous exploiterons la fonction Contexte et celle du vocabulaire spécifique du logiciel Hyperbase, un logiciel d'exploitation statistique documentaire et de traitement quantitatif des grands corpus, élaboré par Étienne Brunet. En effet, Notre démarche pour le traitement de notre corpus par ce logiciel avait abouti à une base de données que nous avons appelée MAUPASSA.EXE. Dans la présentation du vocabulaire spécifique de chaque œuvre, il s’agit de signaler les unités dont la fréquence manifeste un excédent ou un déficit significatif. Pour déterminer le vocabulaire spécifique d’un corpus, le logiciel Hyperbase calcule l’écart réduit de chaque forme dans chacune des parties du corpus. La mise en œuvre du bouton CONTEXTE, permet de voir l’occurrence que l’on cherche dans le contexte du paragraphe. Si l’on clique sur l’un des passages affichés, on a la possibilité de voir la page entière où le mot apparaît. Nous allons donc nous baser sur cette fonction qui fait gagner aux chercheurs un temps considérable en vue de déterminer le sens que Maupassant donne à l’eau dans toutes ses formes.

Abstract:
The results of studies of atmospheric pressure in the Arctic region of Russia for the period from 1948 to 2008 presented. The analysis of the climatic seasonal variation of the atmospheric pressure fields has been carried out. As the main research method, the probabilistic and statistical analysis of the time series of the pressure field during 60 years at fixed points in the region of the Arctic zone of Russia was used. In total, about 90,000 daily (with a six-hour interval) pressure values were studied. Based on these data, the climatic seasonal variability was constructed as an averaging of the values of a given time series at each point in space and for a fixed date. The characteristics of the seasonal cycle, its amplitude and phase have been analyzed. Those characteristics were studied and their geophysical interpretation was carried out. In particular, the minimum and maximum values of the series were determined for the entire region and the time series of these characteristics were constructed. It is shown that the deviation is asymmetrical in nature; this is an unobvious result of research. For the maximum and minimum, the best approximations were proposed, and these approximations were tested by known methods of statistical analysis, including maximum likelihood, least squares and goodness of fit methods (tests), in particular, the ?2 test. The performed study has applications both purely physical (allows to explain the nature, genesis and distribution of large-scale atmospheric formations in a climatic year) and prognostic (allows to understand and track trends in climate, as well as to quantitatively estimate the scale and variability of large-scale atmospheric processes). Numerical calculations were performed on the Lomonosov-2 supercomputer of the Moscow State University named after M.V. Lomonosov.

Abstract:
In 2013, the Irish Government published its National Disability Strategy Implementation Plan 2013-2015. As part of this strategy, a number of goals were set around participation, including job access for people with disabilities. This specific objective recommended a number of actions, including the commitment to publish a comprehensive employment strategy (CES) for people with disabilities. This strategy, the Comprehensive Employment Strategy for People with Disabilities, was published in 2015 for the period 2015-2024. The objective of this strategy, which is cross-governmental, is to support people with disabilities in accessing the labour market. Building on existing actions in the CES, the National Disability Authority (NDA) commissioned the Economic and Social Research Institute (ESRI) to undertake quantitative research into the workplace skills and abilities of persons with disabilities. To undertake this research, a number of nationally representative data sources were utilised to characterise the skills/educational endowments and gaps among persons with disabilities compared to those without. Specifically, data from the Survey on Income and Living Conditions (SILC), the Programme for the International Assessment of Adult Competencies (PIAAC), the Census of Population, and the European Union Statistics on Income and Living Conditions (EU-SILC) were examined. Where the data permitted, we differentiated those with a disability by type, everyday difficulties (e.g. difficulty dressing), and/or severity level. We also examined the employment characteristics of people with disabilities compared to persons without, and investigated the impact of having a disability on an individual’s employment prospects. What follows is a summary of the principal findings from this research, including some discussion on future directions.

As part of this strategy, a number of goals were set around participation, including job access for people with disabilities. This specific objective recommended a number of actions, including the commitment to publish a comprehensive employment strategy (CES) for people with disabilities. This strategy, the Comprehensive Employment Strategy for People with Disabilities, was published in 2015 for the period 2015-2024. The objective of this strategy, which is cross-governmental, is to support people with disabilities in accessing the labour market. Building on existing actions in the CES, the National Disability Authority (NDA) commissioned the Economic and Social Research Institute (ESRI) to undertake quantitative research into the workplace skills and abilities of persons with disabilities. To undertake this research, a number of nationally representative data sources were utilised to characterise the skills/educational endowments and gaps among persons with disabilities compared to those without. Specifically, data from the Survey on Income and Living Conditions (SILC), the Programme for the International Assessment of Adult Competencies (PIAAC), the Census of Population, and the European Union Statistics on Income and Living Conditions (EU-SILC) were examined. Where the data permitted, we differentiated those with a disability by type, everyday difficulties (e.g. difficulty dressing), and/or severity level. We also examined the employment characteristics of people with disabilities compared to persons without, and investigated the impact of having a disability on an individual’s employment prospects. What follows is a summary of the principal findings from this research, including some discussion on future directions.
