Organizational justice in the maritime industry
No full textOrganizational justice is what the individuals who make up an organization expect to receive from the organization in return for the effort they put forth in order to reach the goals of the organization. Knowing the perceptions of employees about organizational justice in terms of job satisfaction and organizational commitment is important for organizational structures. Employees always compare themselves with others in the organizations they belong to. They expect the rules to be applied equally for each person in the organization, the wages to be paid equally for the same job descriptions, to have equal rights in leaves, and to benefit from social opportunities like everybody else. However, the basis of organizational justice perception is not only outputs and comparisons to these outputs, but also the interaction between the rules of the organization and the way these rules are applied and the people in the organization. The rules of the organization and the attitude in the implementation of these rules are important. One of the reasons for the angry behavior in the organization stems from the employees' perception of justice regarding the organization they are affiliated with. If employees realize that they are not treated fairly, they may display some negative and offensive behaviors in order to ensure justice. Such behaviors not only affect the workflow in the organizational structure, but also damage the relations between employees. Considering the labor-intensive structure of the maritime industry, the long working hours of the employees, the tiring and challenging conditions of working at sea, the fact that seafarers are often away from their families and cultures for a long time, and the emotional fatigue caused by all these conditions, it is very important to ensure organizational justice in maritime. Having a substantive organizational justice in the maritime sector is necessary to increase and maintain the qualifications and motivation of maritime workers. In this part of the book, firstly, the concepts of justice and organizational justice will be defined, the principles of organizational justice, its types and the details of the basic theories of organizational justice will be explained, the results of organizational justice will be specified and then the administration of organizational justice in maritime industry will be discussed

Demonstration of ameliorating effect of papaverine in sepsis-induced acute lung injury on rat model through radiology and histology
No full textBackground: Our target was to show the role of high mobility group box-1/receptor for (HMGB1/RAGE) interaction in feces intraperitoneal injection procedure (FIP)-induced acute lung injury (ALI) pathophysiology, to investigate the effect of papaverine on RAGE associated NF-κB pathway by determining the level of soluble RAGE (sRAGE) and HMGB1, and to support this hypothesis by evaluating inflammatory biochemical, oxidative stress markers, Hounsfield unit (HU) value in computed tomography (CT), and histo-pathological results.
Methods: FIP was performed on 37 Wistar rats for creating a sepsis-induced ALI model. The animals were assigned into four groups as follows: Normal control (no treatment), placebo (FIP and saline), and receiving 20 mg/kg and 40 mg/kg per day papaverine. Twenty h after FIP, CT examination was performed for all animals, and HU value of the lung parenchyma was measured. The plasma levels of tumor necrosis factor (TNF)-α, HMGB1, sRAGE, C-reactive protein (CRP) and malondialdehyde (MDA), and lactic acid (LA) were determined and PaO2 and PaCO2 were measured from arterial blood sample. Lung damage was assessed by histopathological.
Results: TNF-, IL-6, CRP, HMGB1, MDA, LA levels, histopathologic scores, and HU values of CT were significantly increased and sRAGE levels were decreased in the saline-treated group against normal group (all P<0.05). Papaverine significantly reversed all results regardless of the dose (all P<0.05) and demonstrated inhibition of HMGB1/RAGE interaction through increasing sRAGE levels and suppresses the pro-inflammatory cytokines
Apoptotic and antiproliferative effects of Inula viscosa L. water extract in the expression of microRnas on HCT 116 cell line: an in vitro study
No full textIn this study, the antiproliferative and apoptotic effects of Inula viscosa L. water extract (IVE) on HCT 116 has been examined, and the change in the expression of miRNAs. Phenolic compounds of IVE were determined as mu g/g extract using by HPLC-DAD. Quantitative determination of apoptosis, cell viability, IC50 values and miRNAs of the cells were determined during 24, and 48 hours. IVE contain coumarin, rosmarinic acid and chlorogenic acid. According to the findings of our study, the expression of miR-21 and miR-135a1 was upregulated, and miR-145 was downregulated in HCT 116 cells (Control). Additionally, IVE was found to have significant potential in regulating miRNAs, downregulating miR-21, miR-31 and miR-135a1, and upregulating miR-145 in HCT-116 cells. All these results show that the anticancer effect of IVE via regulating miRNAs' expression has been demonstrated for the first time, and may be candidate biomarkers in colorectal cancer
Shape analysis of an axisymmetric pendant drop using minimization of free energy
No full textThe shape of a pendant drop is studied by employing free energy minimization. This free energy includes the gravitational potential energy and the interfacial surface energy. We employed the Lagrange multipliers method to minimize free energy while maintaining drop volume as constant. The differential equation for the shape of any pendant drop was established as a function of one dimensionless parameter only. This novel dimensionless parameter is defined as the shape factor. Around the origin of the chosen coordinate axis, an analytical solution to the differential equation was found. For a general solution, a numerical approach was followed to estimate drop shape. Furthermore, we calculated the detached volume from the bulk pendant drop. Comparison of the results with the experimental findings shows good agreements. A new Axisymmetric Drop Shape Analysis method is suggested, which can help users estimate any unknown of the problem if one geometrical data of the drop is know
Empirical investigation on how wellbeing-related infrastructure shapes economic growth: Evidence from the European Union regions
No full textOne of the most important policies of the European Union is regional development, which comprises measures of enhancing economic growth and citizens' living standards via strategic investment. Considering that economic growth and wellbeing are intertwined from the perspective of EU policies, this study examines the relationship between wellbeing-related infrastructure and economic growth in 212 NUTS 2 regional subdivisions across the members of Eu-28 during the period 2001-2020. We therefore analyzed data from 151 Western Europe regions and 61 Central and Eastern Europe regions by means of a panel data analysis with the first-difference generalized method of moments estimator. Our main interest was to determine the degree to which Western Europe regions responded to predictors as compared to Central and Eastern Europe regions. According to the empirical results, the predictors with the strongest influence for Western Europe regions were disposable household income, inter-regional mobility, housing indicator, labor force and participation. For Central and Eastern Europe regions, the largest impact was triggered by the housing indicator, internet broadband access and air pollution. In addition, we determined a relational weighted multiplex between all variables of interest by using dynamic time warping and we introduced topological measures in a multilayer multiplex model for both regional subsamples

Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species
No full textTo enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia)
FIRST CASE REPORT OF ANCA-ASSOCIATED VASCULITIS AND ANTHRACOSIS COEXISTENCE
No full textAnthracosis is a type of mild pneumoconiosis secondary to harmless carbon dust deposits. Although anthracosis was previously associated with inhaled coal particles, such as coal workers' pneumoconiosis, this hypothesis was later abandoned; pathology has been associated with inhaled dust particles. Our paper is the first case report of ANCA-associated vasculitis and anthracosis coexistence. In addition, it aims to highlight that histopathologically proven anthracotic granulomatous nodules can show high FDG uptake in PET/CT contrary to expectation. We present a case of a 73-year-old male with p-ANCA-associated vasculitis and anthracotic lung nodules accompanied by radiological and clinical findings. The patient got diagnosis with p-ANCA-associated vasculitis with serological and rheumatological tests. Atypically, the clinical findings of the patient were weak (No dyspnoea, cough or additional pulmonary complaints). Nodules were present on X-ray graphics and nodules' contours were irregular on CT. On PET/CT, SUV values of the nodules were high [12 kBq/mL]. Histopathological specimens showed multiple lung granulomas including anthracosis particles. Until performing the biopsy, we could not exclude the possibility of malignancy. Conclusion: When lung involvement of vasculitis is superimposed by anthracosis, it can create granulomas with high SUV values. The relationship between anthracosis and parenchymal lung diseases is a current topic and many recently published papers are present on this subject. To the best of our knowledge, our paper is the first paper showing the relationship between parenchymal involvement of vasculitis and anthracosis in the literature. Environmental pollution and dust particles are the known reasons for anthracosis particles in the nodules. It is open to future research on whether air pollution triggers new atypical cases or not
