Published: December 2020

Örgütleri ve bireyleri etkileyen etmenlerden olan dışlanma ve tükenmişlik araştırmacıların ve profesyonellerin zihinlerini meşgul eden olumsuz davranış olarak görülmektedir. Son yıllarda araştırmacılar ve düşünürler bu tür sorunlu davranışların nedenlerini, sonuçlarını ve bunlara etki eden değişkenleri saptamaya çalışmaktadırlar. Bu araştırma ise iş yerinde dışlanmanın bireylerin tükenmişlik düzeylerine etkisini ve bu etkide örgüt temelli öz saygının aracılık rolünün incelemesini amaçlamaktadır. Şanlıurfa ilinde 401 hizmet sektörü çalışanıyla yapılan bu araştırma için nicel araştırma yöntemi benimsenmiştir. Yapısal eşitlik modellemesi ile yapılan analizler sonucu, iş yerinde dışlanmanın tükenmişlik üzerinde pozitif bir etkiye sahip olduğu ve iş yerinde dışlanmanın örgüt temelli öz saygı üzerinde negatif yönlü etkisi olduğu saptanmıştır. Örgüt temelli öz saygının tükenmişlik üzerinde negatif bir etkiye sahip olduğu görülürken, örgüt temelli öz saygının işyerindeki dışlanma ve tükenmişlik arasındaki ilişkiye aracılık ettiği ortaya konmuştur. Araştırmanın sonuçlarına göre örgütlerde kapsayıcı bir kültür oluşturulması, etik kurallar belirlenip işletilmesi ve örgütsel adalet algısının iyileştirilmesi önerilmiştir. Araştırmanın sınırlılıkları ve gelecek çalışmalara yön gösterebilecek bazı kavramlar ifade edilmiştir.

Sediment-routing controls on sandstone bulk petrographic composition and texture across an ancient shelf: Example from Cretaceous Western Interior Basin, Utah and Colorado, U.S.A.
Authors: Lupin Janifar H. , Hampson Gary J.
Published: December 2020

Sediment-routing controls on sandstone texture and bulk petrography have been evaluated in linked alluvial–coastal–shelfal deposits of the Upper Cretaceous Castlegate Sandstone, Blackhawk Formation, Star Point Sandstone, and Mancos Shale (Western Interior Basin, Utah and Colorado, USA) using thin-section analysis of representative outcrop samples in the context of a high-resolution sequence stratigraphic and paleogeographic framework. The studied strata record deposition from two styles of sediment-routing system within an overfilled foredeep and contiguous intra-continental seaway. First, multiple transverse drainages supplied sand to fluvial, shoreline, and shelf segments of sediment-routing systems characterized by down-dip transport distances of 150–450 km and significant strike-oriented sediment transport along the shoreline. Second, the distal shoreline–shelf segment of an axially supplied sediment-routing system was characterized by sand transport for a distance of c. 300 km.

Bulk petrographic composition indicates that transverse sediment-routing systems were sourced from catchments that supplied quartz-rich sand with a subordinate lithic component, while the large axial sediment-routing system was sourced from a catchment(s) supplying slightly more feldspathic sand. Thin-section measurements of mean grain size, sorting, skewness, and ratio of minimum-to-maximum diameter (a proxy for sphericity) are similar for sandstones deposited in fluvial, shoreline, and shelf segments of the transverse sediment-routing systems and in the shoreline–shelf segment of the axial sediment-routing systems, although hydrodynamic sorting is important in locally segregating grain-size populations within each segment. Further, textural analysis of detrital quartz, feldspar, and lithic sand-grain populations shows little evidence of relative change in mean grain size or apparent grain sphericity with downsystem distance, implying that sand-grain populations of different petrographic composition did not undergo significant differential mechanical breakdown during transport. Instead, the textural characteristics of these sand-grain populations are inferred to have been controlled mainly by bedrock lithology and recycling in source catchments. The textural signal of sediment-source areas then propagated downsystem in the sand fraction of detrital sediment supply. This inference is supported by the fine- to medium-grained, well- to very well-sorted character of all sandstone samples, consistent with recycling of sandstones and quartzites from the Sevier fold-and-thrust belt.

Published: December 2020

Background: Type 2 diabetes mellitus (T2DM) and hypertension (HTN) are risk factors for the spectrum of brain lesions. In this paper, we studied the impact of T2DM and HTN on the incidence of several brain lesions diagnosed with magnetic resonance imaging (MRI). Methods and Results: This retrospective, single-center study was conducted at Royal Care International Hospital (Khartoum, Sudan) from January 2016 to December 2016 and included 80 patients (40 male and 40 female, aged between 20 years and 90 years) with suspected brain disorders. MRI brain examinations were conducted on a 1.5 Tesla MRI system (Toshiba Medical Systems, Tokyo, Japan). The following sequences were analyzed: T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), fluid-attenuated inversion recovery (FLAIR), and diffusion-weighted imaging (DWI). Brain lesions were characterized by magnetic imaging spectroscopy and histopathological analysis. Binary logistic regression analysis was used to establish a mathematical model of the relationship between T2DM/HTN and the prevalence of brain lesions. Among 80 patients, HTN, T2D, and the combination of T2D and HTN were identified in 18(22.5%), 9(11.2%), and 11(13.8%) patients, respectively. Brain lesions were found in 48(60%) patients and were most prevalent in the age group of 66-80 years. The brain lesions included ischemic brain infarction (IBI) (22.5%), brain tumors (11.2%), cerebral hemorrhages (6.2%), brain atrophy (BA) (1.2 %), IBI with BA (16.2%), and brain metastases (2.5%). Regression analysis showed that HTN and T2DM were associated with significantly higher ORs for brain lesions ([OR=2.459, 95% CI: 1.673–3.614, P<0.001] and [OR=1.507, 95% CI: 1.067–2.128, P= 0.042], and [OR=1.078, 95% CI:1.033–1.124, P=0.001], respectively). HTN was associated with significantly higher OR for ischemic brain infarction (OR=7.404, 95% CI: 2.600–21.081, P<0.001). Conclusion: The study showed a significant interaction between HTN and T2DM on the prevalence of brain lesions, especially ischemic brain infarction and brain atrophy.

The purpose of our study was to evaluate the common bile duct (CBD) and pancreatic duct (PD) diameter among healthy adult Sudanese subjects using magnetic resonance cholangiopancreatography (MRCP). In addition, this study aimed to determine the effects of age, gender, and body height and weight on the CBD and PD diameters to establish a reference range for these ducts on MRCP, which is very useful in a daily clinical setting where MRCP is commonly performed to evaluate suspected biliary tract disease. Methods and Results: This study included 80 asymptomatic subjects who underwent MRCP. The widest diameter of the CBD and PD was measured perpendicular to their long axes using the electronic caliper. The applied MRCP imaging technique was in line with the guidelines used by Chen et al.(2012) The age, gender, medical history, body height and body weight were recorded. Among the 80 subjects, the mean CBD diameter on MRCP was 6.17±0.69 mm (range of 4-8 mm). There was a significant correlation between the CBD diameter and weight (r=0.407, P<0.001). The mean PD diameter on MRCP was 3.80±0.50mm (range of 2-5 mm). There was also a significant correlation between the PD diameter and weight (r=0.407, P<0.001). In the cohort of 80 subjects, the mean CBD diameter in females was larger than in males(6.50±0.632mm and 5.95±0.677mm, respectively), and this difference was statistically significant (P<0.05). Also, the mean PD diameter in females was statistically larger than in males (6.03±0.66mm and 5.58±0.675mm, respectively), and this difference was statistically significant (P<0.05). Our results demonstrate no significant correlation between the diameter of CBD and PD and participants' height and age. Conclusion: The importance of the current study lies in it’s being one of the few studies whose intention was to use MRCP to bridge the knowledge gap in the literature about the measurement of the CBD and PD diameter among healthy adult Sudanese subjects.
Using Ki-67 Mitotic Activity Markers as a Predictor of the Progression of Adhesions in the Abdominal Cavity
Authors: Shurygina Irina , Shurygin Michael , Chepurnykh Elena , Ayushinova Nataliya
Published: December 2020

Background: Ki-67 is a nuclear protein expressed in all proliferating cells of vertebrates during mitotic cycle phases S, G1, G2, and M, except for G0. Studying this marker is widely used to diagnose the proliferative activity of tumors. However, studying Ki-67 in non-neoplastic diseases attracts much less attention among the researchers. The aim of this study was to assess the possibility of using staining for Ki-67 to identify the proliferative potential of fibroblasts during the formation of adhesions in the abdominal cavity (AC). Methods and Results: Experiments were carried out on male Wistar rats. The adhesion process in AC was simulated in the control group (n=25), and in the experimental group (n=25) with the administration of Seroguard®. Animals were sacrificed on Days 1–30, and the severity of the adhesive process in AC was assessed. Histological sections were prepared and stained for Ki-67. It was found that the animals of the control group had increased severity of the adhesive process in AC during the observation. Maximum increase in severity was registered on Day 30 – 12[9-13] points in the control group and 4[4-4] points in the experimental group (P=0.0079). High proliferative activity of fibroblasts in the control group was detected on Days 3, 7, 14 and 30, which may indicate an active division of fibroblasts and the formation of adhesions in the damaged area. In the experimental group, single Ki-67 positive cells were noted during the entire observation period, which may point to a reduced potential for the formation of adhesions. Conclusion: Our study showed the prospects of using Ki-67 staining to determine the severity of the developing adhesive process in AC, and also revealed one of the possible mechanisms that inhibit the formation of the adhesive process when using Seroguard® – a decrease in the mitotic activity of fibroblasts in the area of peritoneal injury.

Published: December 2020

Background: Health-related quality of life (HRQL) and emotional functioning are important parameters of weight-loss motivation. The aim of this study was to identify the association between emotional/personal characteristics and HRQL in adolescents with overweight and obesity. Methods and Results: Our cross-sectional case-control study included 172 adolescents: 19 of them overweight, 67 obese, and 86 healthy. We measured anthropometry and performed a psychological examination (PedsQL 4.0, The State-Trait Anxiety Inventory, Buss-Durkee Hostility Inventory, and Personality inventory Mini-SMIL). Negative correlations prevailed between PedsQL scales and psychological traits of healthy adolescents: increases in anxiety, covert anger, and depression were associated with a decrease of HRQL (Total Scale Scores, Psychosocial Health Score, Physical Health Score, and Emotional, Social and School functioning). The psychological impairment (Irritability, Resentment, Guilt, Covert anger) positively correlated with a change in HRQL (Total Scale Scores, Psychosocial Health Score, and Physical Health Score) in obese adolescents. Conclusion: Obese adolescents had an inadequate association between HRQL and emotional state: the accumulation of anxiety and aggression was accompanied by an increase in HRQL. These difficulties can be a barrier to having treatment and weight-loss motivation.

Published: December 2020

• Background: Kidney transplantation offers a better quality of life and a clear survival advantage compared to long-term dialysis. However, rates of transplantation are low for highly sensitized patients (HSP) who have a broad specificity of human leucocyte antigen (HLA) specific antibodies. This is because the presence of pre-formed HLA Donor Specific Antibodies can result in hyperacute rejection and is an immunological veto to transplantation. The proportion of eligible donors therefore decreases with increasing sensitization, resulting in increased waiting time prior to transplantation. This study aims to assess the efficacy of a combination of B cell depletion and proteasome inhibition, together with antibody removal and steroids, to reduce HLA antibodies in HSP, predicted to improve rates of transplantation, and to determine the feasibility of conducting a future definitive trial. • Methods: ITOPS is a multi-center, randomized parallel, non-blinded, controlled phase III feasibility trial. The participants will be allocated in a 1:1 ratio to either the trial intervention (rituximab followed by 1-2 cycles of plasmapheresis, bortezomib and dexamethasone) or control group (no intervention). • Discussion: The primary outcome is the proportion of patients achieving an absolute reduction in sensitization (calculated reaction frequency, cRF) of at least 10% at 12 weeks following their last intervention, compared to the control group. Secondary outcomes include recruitment and transplantation rates, durability of change and absolute percentage change in cRF, and acceptability of the intervention. We will proceed to development of a larger trial if at least 50% of the participants in the intervention arm achieve an absolute reduction in cRF of a minimum of 10% at 12 weeks following their last intervention. If the proportion is <50% in the intervention arm but 50% is included within the 95% confidence interval, then consideration to proceed to a larger randomized trial will be given alongside other aspects of feasibility.• Trial Registration: International Standard Randomized Controlled Trial Number ISRCTN66441193 https://doi.org/10.1186/ISRCTN66441193

Rational design of noble catalysts with a potential to leverage efficiency at the atomic scale is vital for industrial applications. Such an ultimate atom-utilization efficiency can be achieved when all noble atoms exclusively contribute to catalysis. Here, we demonstrate a scalable synthesis of freestanding amorphous PtSex (where 1.2 < x < 1.3) layers acting as single-atom-layer of Pt catalysts with an unprecedentedly high atom-utilization efficiency (~ 30 wt%) at the monolayer limit. The amorphous PtSex behaviors a fully-activated surface accessible to catalytic reactions. The catalytic performance of the amorphous layer is featured by a nearly 100% current density relative to a pure Pt surface and reliable production of sustained high-flux hydrogen over a 2-inch sized wafer sample as a proof-of-concept. Furthermore, an electrolyser using the PtSex amorphous layer as a cathode is demonstrated to generate a high current density of 1000 mA cm− 2. Such an amorphization strategy is potentially extendable to other noble metals, including Pd, Ir, Os, Rh, and Ru elements, demonstrating the universality of single-atom-layer catalysts.

Published: December 2020

Introduction: Local recurrence (LR) threatens the treatment of esophageal squamous cell carcinoma (ESCC). This study interrogated the optimal re-irradiation dose for the LRESCC following radical (chemo) radiotherapy.Methods: We retrospectively analyzed a total of 125 patients with LRESCC after initial radiotherapy. For the radiotherapy dose, 58 patients were assigned to low-dose (LD) group (50–54 Gy) while the remaining 67 were classified into the high-dose (HD) group (55–60 Gy). We recorded the response rate (complete + partial response), 1-, 2- and 3-year survival rate, and toxicity. We then analyzed the impact of the different radiotherapy doses, and combination chemotherapy on the survival of the LRESCC patients.Results: After re-irradiation, the 1-, 2- and 3-year survival rates were 48.3%, 24.1% and 10.3% in the LD group, and 61.2%, 34.3% and 19.4% in the HD group (P<0.05), respectively. The median survival time of patients receiving radiotherapy alone was 9 months in the LD group and 15 months in the HD group (P<0.05). Whereas the survival rate of patients treated with chemoradiotherapy was higher than that of patients treated with radiotherapy alone in the LD group, chemoradiotherapy showed no advantage over radiotherapy alone in the HD group. In addition, the incidence of esophagitis, the most common toxicity, was higher in the HD group compared to the LD group (68.7% vs 58.6%, P<0.05). Our multivariate analysis demonstrated that re-irradiation dose was an independent favorable prognostic factor in patients with LRESCC.Conclusion: Taken together, our data shows that, increasing the re-irradiation therapy dose (55-60Gy) improves the long-term survival of patients with LRESCC after radiotherapy, with tolerable toxicity.

Published: December 2020

Background: Histopathological examination of prostatic specimen is gold standard for the diagnosis of prostate cancer. Current study evaluates the expression of AMACR and p63 in the prostate lesions using AMACR and p63 cocktail.

Materials and Method: Total of 180 cases were collected and Haematoxylin and Eosin staining performed followed by immunohistochemical analysis using AMACR and p63 antibody.

Result: Out of 180 cases, Benign Prostatic Hyperplasia is the most common lesion noted in about 120 cases. In this study, the predominant population was in the 6th to 7th decade of age. Most of the patients presented with difficulty in micturition. Immunohistochemistry revealed that p63 expression is positive in all normal basal cells, 118 cases (98.33%) were negative for AMACR and only 2 cases were showing focal and weak AMACR immunoreactivity. AMACR was positive in all the 6 HGPIN cases with variable intensity. Out of 5 LGPIN cases AMACR was positive in 3 cases with low intensity, remaining 2 cases shows AMACR negative. p63 is positive in all 11 PIN cases (LGPIN & HGPIN) showing discontinuous staining pattern. All 22 cases of Prostatic adenocarcinomas were negative for p63 and all cases expressed positive immunostaining with AMACR. A diagnosis of adenocarcinoma was made in 48% of atypical cases. Cases which were negative for both AMACR and p63 were diagnosed as Atypical Small Acinar Proliferation, for which further follow-up is required.

 

Conclusion: AMACR/p63 Cocktail antibody is very much useful as it saves time, tissue and is cost-effective.

Published: December 2020

Background: Skin adnexal tumours are a category of rare tumours. They usually present as painless nodules and papules. The diagnosis of these tumours poses a challenge, because there is usually a discrepancy in clinical and histopathological diagnosis.

Aims: To study the skin biopsies received in our department and compare their clinical and histopathological diagnosis.

Material and methods: Prospective study of skin biopsies received in our department over a period of 1 year. The biopsies were processed and stained with haematoxylin and eosin and studied under the light microscope.

Results: Out of the 26 cases studied, 25 were found to be benign tumours with a single case of keratoacanthoma. The most common tumour encountered was pilomatricoma and the least common was syringoma. Only four cases showed clinical correlation with histopathological diagnosis.

Conclusion: It can be therefore concluded that skin adnexal tumours are rare tumours which need histopathological examination for their accurate diagnosis.

Published: December 2020

Chronic myelomonocytic leukemia is a heterogeneous syndrome with features of both myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN). The varied clinical presentations add to the distinctiveness of the disease. This heterogeneity should invigorate the search for reliable predictors of evolution and progression of disease. We report a case series from a tertiary care centre in Kerala, South India. This was a retrospective observational study of all cases of CMML, which was diagnosed in the departments of Pathology and Clinical Haematology & Haemato- oncology of our institution between January 2017 to May 2020. The clinical presentation, laboratory investigations, and treatment details were noted. Nine cases of CMML were encountered during the study period. The mean age of study subjects was 70.4 years with a female predilection. Fever and weight loss were the most common clinical presentations. Four patients were classified as CMML- 2, three patients as CMML- 1, and two as CMML- 0. Based on the WBC count, five patients were classified as dysplastic and four as proliferative subtypes. Two patients had grade 1/3 (one case each of CMML- 2 and CMML- 1) and one patient had grade 2/3 fibrosis (a case of CMML- 1) in the bone marrow. Thirty-three percentage patients had clonal cytogenetic abnormalities, the commonest being trisomy 8. Renal function was deranged in three patients and two patients had a deranged liver function and hepatomegaly. Four patients underwent treatment with hypomethylating agents or cytoreduction with hydroxyurea. One of the patients (CMML- 2 with marked leucocytosis) succumbed to disease.

Published: December 2020

Microalgal bioremediation is currently being venerated for its potential in municipal liquid waste (MLW) treatment. Algae-based water treatment with retention time competitive to the conventional water treatment processes is a challenge. The present study investigated the role of algal biomass concentration to improve treatment efficiency to reduce the time required for water treatment. Eighty percent removal of pollutants (in terms of chemical oxygen demand (COD), ammonia, phosphate and fecal coliforms) was obtained in 12 hours at a biomass concentration of 1 gL−1. Further, continuous treatment of MLW using membrane-assisted photobioreactor was established. The treatment led to >95% removal of ammonia, >75% removal of COD and 100% removal of fecal coliforms within 12 hours. Physiological assessment of the algal culture showed that the cells did not manifest symptoms of stress throughout the reactor cycle, a consequence of continuous availability of the nutrients, maintaining the culture in continuous growth state.

Published: December 2020

Stormwater management through Blue-Green Infrastructure (BGI) delivers multiple benefits across urban environments. However, current integrated modelling tools fail to provide a simplified way of assessing these benefits. In this study, we reflected upon the development of an interdisciplinary BGI planning-support tool, known as the Water Sensitive Cities Toolkit (the WSC Toolkit) and offer guidance for effective tool development going forward. Based on interdisciplinary research, the WSC Toolkit incorporates a suite of independent sub-modules but can be connected together to provide integrated assessment, allowing evidence-based quantification of multiple benefits associated with BGI, e.g., stormwater treatment and harvesting, stream hydrology, erosion, minor flooding, urban microclimate, etc. Distinguished from other larger complex models, the WSC Toolkit was characterised by its simplicity, modularity and extensibility, providing scenario-based integrated assessment of these benefits. Through case studies, we demonstrated how the WSC Toolkit can be used to support improved decision-making towards maximising the benefits of BGI. We also showed how it can act as a platform for practical application of latest research outcomes and meanwhile encouraging interdisciplinary collaboration. We reflect upon five key lessons that could guide future researchers in developing effective integrated assessment tools, particularly within highly interdisciplinary fields such as BGI.
The status of freshwater and reused treated wastewater for agricultural irrigation in the Occupied Palestinian Territories
Authors: Salem Hilmi S. , Yihdego Yohannes , Muhammed Hadi Hamaaziz
Published: December 2020

Global freshwater scarcity is imposing the demand for using non-conventional water resources for irrigation and non-irrigation purposes. Direct reuse of treated wastewater for agricultural irrigation is a widespread practice in arid and semi-arid regions, because of water shortage and scarcity. Water scarcity and the need for ecological sustainability have led to the introduction of treated wastewater as an additional water resource in the national water resources' management plans of Mediterranean countries. The use of wastewater for irrigation is an important tool for water resources' supplement. However, the reuse of effluent in irrigation can have negative impacts on crop quality and soil conditions, as well as on public health and the environment. Furthermore, inappropriate management of agricultural irrigation with treated wastewater can also pose problems for plant production and the physical and chemical properties of soils. This paper presents some approaches to understand the impacts of reusing treated wastewater. It also presents a critical analysis of the treated wastewater's reuse for irrigation in the Occupied Palestinian Territories (OPT), while shedding light on the water status in the OPT. The paper investigates the wastewater treatment and reuse for agricultural irrigation, especially in the lack of control of Palestinians on their own freshwater resources in the OPT.
Knowledge donating and hiding as an organizational basis for intersectoral collaboration: a review of the literature
Authors: Iriarte-Ahón Federico
Published: December 2020

The present article presents a literature review on the relationship between knowledge donating and hiding strategies as an organizational basis for intersectoral collaboration. The literature finds that sharing or hiding behavior is a question of individual motivation, which can affect the collaboration process among individuals in a public or private organization. An understanding of this motivation can help organizations to transform their management strategies, thus improving internal and inter-organizational collaboration processes. The review identified various strategies— motivational, social, and national cultural—that are considered to influence individual and group creative capacity and, in turn, on social and technological innovation, the creation of competitive advantage within an organization, and the development of social responsibility policies. The results indicate a lack of consensus regarding motivations, as well as a limited depth of knowledge regarding the behavioral strategies involved in knowledge hiding.

Published: December 2020

In recent years the need for responsible management of financial institutions, in terms of organizational commitment to supporting society and strategies for sustainable economic development, has become increasingly pressing. The aim of this article is to determine the influence that management has on job satisfaction and performance at banking firms based in northeast Mexico. The primary data were obtained using an instrument applied to management-level employees of public and private banking firms in the cities of Ensenada and Tijuana in Baja California; and Hermosillo, Guaymas, Ciudad Obregón, and Navojoa in Sonora. The statistical technique of linear regression modeling was used to analyze and validate the results, with the aid of the Statistical Package for the Social Sciences (SPSS), version 25. The results show that managerial commitment is a key factor in the organizational performance of responsible banking. Thus, the greater the management responsibility for socially responsible actions, the stronger the positive influence on employees’ job satisfaction in the sector. It was also found that the banks are generally well predisposed to corporate social responsibility, and that commitment has a positive and significant relationship with the performance of these institutions.

O evento, que reúne a dimensão de um festival de culturas e a de um fórum de debates e conversas sobre políticas culturais entre populações tradicionais, gestores públicos, pesquisadores, produtores, artistas, entre outros, foi concebido e apoiado enquanto uma ação de difusão e valorização das culturas populares e tradicionais. A proposta aqui é analisar especificamente o contexto que permite a emergência do ECTCV, o lugar do evento nas políticas públicas culturais e sua experiência com as mesmas ao longo de suas várias edições e em diferentes momentos do cenário das políticas culturais a nível nacional, assim como problematizar o formato e organização do evento. O material aqui reunido se baseia em documentos, entrevistas e trabalho de campo realizado entre os anos 2015 e 2017 no ECTCV.

Este trabalho busca analisar o efeito da educação, da experiência e da idade no salário de trabalhadores formais no setor de turismo para o Estado do Espírito Santo. Também são investigadas eventuais disparidades salariais entre homens e mulheres e discriminação por raça/cor. Para tal faz-se uso dos microdados da Relação Anual de Informações Sociais (RAIS) dos anos 2006 e 2016, presentes na plataforma do Ministério da Economia. Os resultados obtidos através das regressões por Mínimos Quadrados Ordinários (MQO) e MQO com correção robusta foram estatisticamente significativos em sua vasta maioria. Escolaridade, idade e experiência tiveram os sinais positivos esperados, ceteris paribus, a partir das estimações verificou-se que, em média, as mulheres recebem salários menores que os homens em trabalhos formais no turismo, e não foi verificada uma expressiva diferença salarial por raça/cor.

O artigo tem como objetivo investigar ações governamentais desenvolvidas no distrito de Serra Negra, Pernambuco, voltadas para a atividade turística. Esta pesquisa qualitativa e descritiva está relacionada a ações governamentais no período de 2013 a 2018. A coleta de dados é baseada em documentos institucionais nos níveis nacional, estadual e municipal, além de entrevista semiestruturada com a gestora municipal de turismo. Observou-se que algumas ações foram concluídas e outras, que se concentram diretamente na preservação da região, ainda estão em fase de elaboração ou implementação. Algumas ações são desconhecidas da administração local, apesar de mencionadas em documentos do governo estadual. Serra Negra foi inserida em três Programas como objeto de políticas públicas: Prodetur Nacional de Pernambuco, Pernambuco para o Mundo e Regionalização do Turismo. As informações sobre a execução local do Programa Pernambuco para o Mundo e do Programa de Regionalização do Turismo não foram obtidas a partir da pesquisa documental, nem da entrevista, o que pode indicar que essas políticas públicas não foram realizadas. No caso do Prodetur Nacional de Pernambuco, o projeto de valorização turística da região foi parcialmente realizado. Há uma gestão desarticulada entre o poder local e a liderança das ações do poder estadual, por isso é necessário fortalecer a institucionalização municipal para que atuem mais ativamente nas decisões de turismo. Além de fortalecer a gestão local, é necessário ativar o Conselho Municipal para que os interesses dos atores privados, o terceiro setor e a comunidade local também possam ser incluídos na agenda pública do turismo.

En este trabajo se presenta un estudio comparativo de la impedancia de un electrodo vertical enterrado en un suelo homogéneo donde los parámetros eléctricos (resistividad y permisibilidad) son dependientes de la frecuencia en relación a los mismos con parámetros constantes. Para su cálculo, es llevado en consideración que el electrodo vertical se puede interpretar como una línea de transmisión (LT) cuyos los parámetros eléctricos son distribuidos por unidad de longitud. Así, la impedancia del electrodo es computada como siendo la impedancia harmónica de LT en función de la frecuencia. Una vez obtenidas las impedancias de aterramiento del electrodo, y empleando una técnica de mínimos cuadrados, se las representan por circuitos eléctricos directamente en el dominio del tiempo. La ventaja de usar este tipo de representación es que el modelo puede insertarse fácilmente en software del tipo EMTP para el análisis de los transitorios electromagnéticos.  Así, se calculan las elevaciones de potencial en el aterramiento para una descarga atmosférica incidente en el electrodo.  Adicionalmente, una descarga atmosférica es inyectada en el topo de una torre de transmisión aterrada por un electrodo vertical, para evaluar las tensiones en los brazos de la estructura y en su base.  Los resultados muestran que las tensiones son significativamente modificadas por la presencia del suelo con parámetros dependientes de la frecuencia, en especial las amplitudes, y que un análisis preciso del transitorio en los sistemas eléctricos debe llevar en cuenta ese fenómeno.

Изучена диффузия атомов индия в пленках SiO2, предварительно имплантированных ионами мышьяка с разной энергией, в зависимости от температуры последующего отжига. Установлено, что диффузионные свойства индия зависят от присутствия в пленке атомов мышьяка и их энергии. Увеличение концентрации мышьяка в области средних пробегов ионов In+ предотвращает диффузию индия к поверхности SiO2 при высоких температурах отжига и стимулирует диффузию In вглубь в форме одновалентного междоузлия. Обнаруженные эффекты объяснены с точки зрения формирования пар In-As в соседних замещающих положениях в матрице SiO2. Ключевые слова: индий, мышьяк, диффузия, оксид кремния, ионная имплантация.

In this work, we studied textured ZnO films obtained by ion-beam deposition. X-ray diffraction patterns and micrographs of the surface revealed that asdeposited films have a polycrystalline structure. It was found that, after annealing of the samples in the temperature range from 200 ° C to 500 °, recrystallization occurs, leading to a change in the grain size and surface roughness. The dependence of the initial state of the film on the recrystallization intensity is also demonstrated. In films with an initially more perfect structure, temperature treatment at 500 ° C led to grain growth by more than 2 times and a decrease in roughness by ~ 40%.

The high-temperature (T = 1880◦C) Be-ions diffusion and electron irradiation influence on the AlN monocrystals optical properties were investigated. We demonstrated that Be diffusion into AlN leads to spectral properties change of the Raman scattering and infrared absorption. The analysis of the Raman
and infrared absorption spectra of the AlN crystals, containing Be impurity, proves that Be impurity is a getter for intrinsic impurities, which are responsible for AlN crystals yellow color manifestation and spectral lines broadening

The influence of electrode topology on the electrical and photoelectric characteristics of metal/semiconductor/metal structures was investigated. Gallium oxide films were obtained by radio-frequency sputtering of a Ga2O3 target onto sapphire substrates with the (0001) orientation. Two types of electrodes were formed on the surface of the oxide films: two parallel electrodes with an interelectrode distance of 250 mkm and interdigitated ones. The distance between the "fingers" of the detectors of the second type was 50, 30, 10, and 5 mkm. Regardless of the type of contacts, the structures exhibit sensitivity to ultraviolet radiation with a wavelength of λ = 254 nm. Detectors of the second type with an interelectrode distance of 5 μm demonstrate the highest values of the photocurrent Iph = 3.8 mA and detectivity D * = 5.54⋅10^15 cmHz^0.5W^-1.

The results of a study of the electroluminescence of the asymmetric InAs/InAs1−ySby/InAsSbP LED heterostructures with a molar fraction of InSb in the ternary solid solution in the active region y=0.15 and y=0.16 in the temperature range 4.2−300 K are presented. Based on the experimental data, the formation of a staggered type II heterojunction at the InAs1−ySby/InAsSbP heterointerface was determined. The dominant contribution of the interface radiative transitions at the type II heterointerface in the temperature range 4.2−180 K was shown, which makes it possible to minimize the temperature dependence of the operating wavelength of the LEDs.

It was studied the possibility of laser annealing modification of the properties of the (Ga,Mn)As layer located on the surface of a quantum-well InGaAs/GaAs structure, while retaining its radiative properties. The structures with four InGaAs/GaAs quantum wells (indium content was varied from 0.08 to 0.25), located at different distances from the (Ga,Mn)As layer, were fabricated by combining the methods of MOCVD-hydride epitaxy and pulsed laser deposition. The LPX-200 excimer laser pulse energy density was varied from 200 to 360 mJ/cm2, and the depth of laser action was determined from the change in the photoluminescence spectra of the quantum wells. In describing the results obtained, a model of the laser annealing process was used, based on solving the problem of heat propagation in a one-dimensional GaAs system, taking into account the (Ga,Mn)As layer on the surface. Changes in the structural and galvanomagnetic properties of the samples as a result of laser irradiation were analyzed. It is shown that as a result of pulsed laser action at a laser energy density range of 250 - 300 mJ/cm2, it is possible to preserve the emissive properties of the active region (InGaAs/GaAs quantum well) located at a distance of 10 - 12 nm from the (Ga,Mn)As layer and modify ferromagnetic properties of the semiconductor (Ga,Mn)As, namely: to increase the temperature of the ferromagnet-paramagnetic phase transition to values of at least 120 K. The results obtained are promising for the development of technology for devices of spin optoelectronics.

In this paper the electrical and dielectric properties of polycrystalline yttrium iron garnet, obtained by the radiation-thermal sintering technology in a fast electron beam were investigated. Spectra of complex dielectric constant, dielectric loss tangent and conductivity were measured in the frequency range 25 – 1∙106 Hz. For comparison, DC resistance measurements were also performed. The temperature dependences of the above parameters were measured at frequencies of 1 kHz, 100 kHz in the range 25 - 300 °C. It is shown, that conduction activations energy, permittivity, loss tangent and resistance vary significantly from sintering temperature in the range of 1300 to 1450 °C. It is found that with an increase in the sintering temperature to 1450 °C, dielectric properties are the same as samples made by the traditional ceramic technology.
