Danos Ocupacionais associados ao Cádmio, com ênfase no setor da Conservação e Restauro de Obras de Arte
Authors: Santos Mónica , Almeida Armando
Published: January 2021

Introduction and objective The authors aimed to collect and summarize all the information they found on the subject, as a starting point for other projects that are considered pertinent in the context of the occupational health of these professionals. The main risks associated with Cadmium are distributed through diverse medical contexts (although with different consensos) in neurology, cardiovascular system, reproduction/ obstetrics, pediatrics, nephrology, oncology, pulmonology, ophthalmology, gastrointestinal tract, endocrinology and orthopedics/ rheumatology. Methodology This scoping review used search engines as PubMed; Web of Science; Science Direct; Academic Search Complete; CINALH; MedLine; Database of Abstracts and Reviews; Central Register of Controlled Trials; Cochrane Database of Systematic Reviews; Nursing and Allied Health Collection; MedicLatina and RCAAP. Content or Results In this professional context, one document was found mentioning that in the eighteenth and nineteenth centuries pigments associated with cadmium, although toxic, but still used today, were discovered; the most relevant are (in frequency and toxicity) yellow and red cadmium, used since 1820 and 1910, respectively. Another article emphasized that during the 19th century yellow pigments were created with cadmium sulphide, and this color also depended on the addition of elements such as zinc, selenium and barium. Discussion There is so little bibliography on Cadmium’s medical risks in Conservators-Restorers that the authors have chosen to include in this section some data regarding other professionals who may also contact with this agent. Among these, the artists who elaborate (or have elaborated in the past) works of art with pigments with Cadmium, may be the most adequate, although also on these the bibliography is very reduced. It is believed that famous painters were exposed, namely Rubens, Renoir, Duffy and Klee. Limitations The authors made efforts to make their research exhaustive but, once completed, they realized that they did not find relevant data on Cadmium dosing in Conservation and Restoration workplaces in general, nor did they indicate which techniques may be used or which are preferable, such as biological monitoring. No evaluation of the associated risk was found for this professionals. Collective or individual protection measures were not mentioned in the bibliography consulted (even in generic terms, let alone specifying models and/ or materials). Conclusions It has long been known that concrete and serious harm is associated with Cadmium. However, the Conservation and Restoration sector is still very little studied in the context of Occupational Health and the risks of eventual contact with Cadmium are no exception. It would be very pertinent to have motivated teams to study this sector and to fill some of the limitations found, not developed in the international literature.
Family Dynamics: An Intergenerational Study on Asian American Narratives
Authors: Bhandari Nagendra Bahadur
Published: January 2021

The relationship in Asian immigrant families ranges from intergenerational and intercultural conflict to mutual understanding over the period of the time. Shaped by different cultural contexts of native and host land, the first and second-generation immigrants have varying world views, perceptions and attitudes rendering conflicts of interests in their priorities. These differences are further widened by their generational differences. However, they negotiate their cultural differences and show mutual understanding, respect for differential priorities and flexibility for co-optation of diverse cultural practices. They involve in dynamic intergenerational relationship full of inconsistencies and contradictions, which keeps of changing in different contexts over the period of time. This article explores the dynamic relationship of the first and second-generation immigrants in Asian-American narratives: The Namesake by Jhumpa Lahiri, The Bonesetter’s Daughter by Amy Tan, Native Speaker by Change rae Lee and Chorus of Mushrooms by Hiromi Goto. Both generation immigrant characters in these narratives constantly vacillate between the cultural spaces of their home and host countries in their negotiation of intergenerational relationship. This article analyzes the cultural vacillation of immigrants in the critical frame of Stuart Hall’s cultural identity which he conceptualizes in his notion of being and becoming.
Pedicled Tubular Omental Patch for Tamponade of Transfixing Gunshot Bilobar Liver Injury: A Case Report
Authors: Zanellato Artur , Zanellato Artur , Thompson Rory , Zanellato Gabriella , Collaco Iwan , Paterson-Brown Simon
Published: January 2021

Introduction: Liver injuries are frequent in abdominal trauma and may be managed using a variety of
methods. The operative management of deep, penetrating wounds generally involves balloon tamponade of
the wound tract using a Sengstaken-Blakemore catheter.
Case Presentation: A haemodynamically unstable 34-year-old male with multiple thoracoabdominal
gunshot wounds was transferred to the operating theatre. At laparotomy, a grade 3 transfixing (through and
through) bilobar hepatic wound was discovered with active hemorrhage. Unfortunately, no suitable balloon
catheters were available, so, as an alternative, tamponade of the wound tract was successfully achieved
using a tubular omental patch.
Discussion: Omental patches are commonly used in the management of perforated duodenal ulcers and
have been used to prevent recurrence following hepatic cyst de-roofing. To the authors’ knowledge, this is
the first description of this technique for the management of penetrating bilobar transfixing hepatic injury.
Conclusion: A tubular omental patch may be used to achieve tamponade of deep wounds in penetrating
hepatic trauma. This could be a particularly useful technique in resource-poor environments, or where a
suitable balloon catheter is otherwise unavailable.

A human brain test bed for research in large vessel occlusion stroke
Authors: Gebrezgiabhier Daniel , Liu Yang , Reddy Adithya S. , Davis Evan , Zheng Yihao , Shih Albert J. , Pandey Aditya S. , Savastano Luis E.
Published: January 2021

OBJECTIVE

Endovascular removal of emboli causing large vessel occlusion (LVO)–related stroke utilizing suction catheter and/or stent retriever technologies or thrombectomy is a new standard of care. Despite high recanalization rates, 40% of stroke patients still experience poor neurological outcomes as many cases cannot be fully reopened after the first attempt. The development of new endovascular technologies and techniques for mechanical thrombectomy requires more sophisticated testing platforms that overcome the limitations of phantom-based simulators. The authors investigated the use of a hybrid platform for LVO stroke constructed with cadaveric human brains.

METHODS

A test bed for embolic occlusion of cerebrovascular arteries and mechanical thrombectomy was developed with cadaveric human brains, a customized hydraulic system to generate physiological flow rate and pressure, and three types of embolus analogs (elastic, stiff, and fragment-prone) engineered to match mechanically and phenotypically the emboli causing LVO strokes. LVO cases were replicated in the anterior and posterior circulation, and thrombectomy was attempted using suction catheters and/or stent retrievers.

RESULTS

The test bed allowed radiation-free visualization of thrombectomy for LVO stroke in real cerebrovascular anatomy and flow conditions by transmural visualization of the intraluminal elements and procedures. The authors were able to successfully replicate 105 LVO cases with 184 passes in 12 brains (51 LVO cases and 82 passes in the anterior circulation, and 54 LVO cases and 102 passes in the posterior circulation). Observed recanalization rates in this model were graded using a Recanalization in LVO (RELVO) scale analogous to other measures of recanalization outcomes in clinical use.

CONCLUSIONS

The human brain platform introduced and validated here enables the analysis of artery-embolus-device interaction under physiological hemodynamic conditions within the unmodified complexity of the cerebral vasculature inside the human brain.
Retrospective analysis of open surgical versus laser interstitial thermal therapy callosotomy in pediatric patients with refractory epilepsy
Authors: Caruso James P. , Janjua M. Burhan , Dolce Alison , Price Angela V.
Published: January 2021

OBJECTIVE

Corpus callosotomy remains an established surgical treatment for certain types of medically refractory epilepsy in pediatric patients. While the traditional surgical approach is often well tolerated, the advent of MR-guided laser interstitial thermal therapy (LITT) provides a new opportunity to ablate the callosal body in a minimally invasive fashion and minimize the risks associated with an open interhemispheric approach. However, the literature is sparse regarding the comparative efficacy and safety profiles of open corpus callosotomy (OCC) and LITT callosotomy. To this end, the authors present a novel retrospective analysis comparing the efficacy and safety of these methods.

METHODS

Patients who underwent OCC and LITT callosotomy during the period from 2005 to 2018 were included in a single-center retrospective analysis. Patient demographic and procedural variables were collected, including length of stay, procedural blood loss, corticosteroid requirements, postsurgical complications, and postoperative disposition. Pre- and postoperative seizure frequency (according to seizure type) were recorded.

RESULTS

In total, 19 patients, who underwent 24 interventions (16 OCC and 8 LITT), were included in the analysis. The mean follow-up durations for the OCC and LITT cohorts were 83.5 months and 12.3 months, respectively. Both groups experienced reduced frequencies of seizure and drop attack frequency postoperatively. Additionally, LITT callosotomy was associated with a significant decrease in estimated blood loss and decreased length of pediatric ICU stay, with a trend of shorter length of hospitalization.

CONCLUSIONS

Longer-term follow-up and a larger population are required to further delineate the comparative efficacies of LITT callosotomy and OCC for the treatment of pediatric medically refractory epilepsy. However, the authors’ data demonstrate that LITT shows promise as a safe and effective alternative to OCC.
Endoscopic transorbital approach to the insular region: cadaveric feasibility study and clinical application (SevEN-005)
Authors: Kim Eui Hyun , Yoo Jihwan , Jung In-Ho , Oh Ji Woong , Kim Ju-Seong , Yoon Jin Sook , Moon Ju Hyung , Kang Seok-Gu , Chang Jong Hee , Roh Tae Hoon
Published: January 2021

OBJECTIVE

The insula is a complex anatomical structure. Accessing tumors in the insula remains a challenge due to its anatomical complexity and the high chance of morbidity. The goal of this study was to evaluate the feasibility of an endoscopic transorbital approach (ETOA) to the insular region based on a cadaveric study.

METHODS

One cadaveric head was used to study the anatomy of the insula and surrounding vessels. Then, anatomical dissection was performed in 4 human cadaveric heads using a dedicated endoscopic system with the aid of neuronavigation guidance. To assess the extent of resection, CT scanning was performed before and after dissection. The insular region was directly exposed by a classic transcranial approach to check the extent of resection from the side with a classic transcranial approach.

RESULTS

The entire procedure consisted of two phases: an extradural orbital phase and an intradural sylvian phase. After eyelid incision, the sphenoid bone and orbital roof were extensively drilled out with exposure of the frontal and temporal dural layers. After making a dural window, the anterior ramus of the sylvian fissure was opened and dissected. The M2 segment of the middle cerebral artery (MCA) was identified and traced posterolaterally. A small corticectomy was performed on the posterior orbital gyrus. Through the window between the lateral lenticulostriate arteries and M2, the cortex and medulla of the insula were resected in an anteroposterior direction without violation of the M2 segment of the MCA or its major branches. When confirmed by pterional craniotomy, the sylvian fissure and the MCA were found to be anatomically preserved. After validation of the feasibility and safety based on a cadaveric study, the ETOA was successfully performed in a patient with a high-grade glioma (WHO grade III) in the right insula.

CONCLUSIONS

The transorbital route can be considered a potential option to access tumors located in the insula. Using an ETOA, the MCA and its major branches were identified and preserved while removal was performed along the long axis of the insula. In particular, lesions in the anterior part of the insula are most benefited by this approach. Because this approach was implemented in only one patient, additional discussion and further verification is required.
Institutional review of the management of type II odontoid fractures: associations and outcomes with fibrous union
Authors: Wilson Christopher , Hoyos Mariana , Huh Andrew , Priddy Blake , Avila Stephen , Mendenhall Stephen , Anokwute Miracle C. , Eckert George J. , Stockwell David W.
Published: January 2021

OBJECTIVE

Type II odontoid fractures may be managed operatively or nonoperatively. If managed with bracing, bony union may never occur despite stability. This phenomenon is termed fibrous union. The authors aimed to determine associations with stable fibrous union and compare the morbidity of patients managed operatively and nonoperatively.

METHODS

The authors performed a retrospective review of their spine trauma database for adults with type II odontoid fractures between 2015 and 2019. Two-sample t-tests and Fisher’s exact tests identified associations with follow-up stability and were used to compare operative and nonoperative outcomes. Sensitivity, specificity, and predictive values were calculated to validate initial stable upright cervical radiographs related to follow-up stability.

RESULTS

Among 88 patients, 10% received upfront surgical fixation, and 90% were managed nonoperatively, of whom 22% had fracture instability on follow-up. Associations with instability after nonoperative management include myelopathy (OR 0.04, 95% CI 0.0–0.92), cerebrovascular disease (OR 0.23, 95% CI 0.06–1.0), and dens displacement ≥ 2 mm (OR 0.29, 95% CI 0.07–1.0). Advanced age was not associated with follow-up instability. Initial stability on upright radiographs was associated with stability on follow-up (OR 4.29, 95% CI 1.0–18) with excellent sensitivity and positive predictive value (sensitivity 89%, specificity 35%, positive predictive value 83%, and negative predictive value 46%). The overall complication rate and respiratory failure requiring ventilation on individual complication analysis were more common in operatively managed patients (33% vs 3%, respectively; p = 0.007), even though they were generally younger and healthier than those managed nonoperatively. Operative or nonoperative management conferred no difference in length of hospital or ICU stay, discharge disposition, or mortality.

CONCLUSIONS

The authors delineate the validity of upright cervical radiographs on presentation in association with follow-up stability in type II odontoid fractures. In their experience, factors associated with instability included cervical myelopathy, cerebrovascular disease, and fracture displacement but not increased age. Operatively managed patients had higher complication rates than those managed without surgery. Fibrous union, which can occur with nonoperative management, provided adequate stability.
Effects of end-plate on the critical moment of I-section cantilever beam with free end restrained laterally
Authors: Khanh Trinh Duy , Tuyen Nguyen Minh , Cuong Bui Hung
Published: January 2021

Effects of end-plate on the lateral buckling of doubly symmetrical I-section cantilever beam with free end restrained laterally are analyzed using the software COMSOL and linear shell finite elements. The torsional stiffness of the end-plate prevents the free warping of flanges and decreases the warping effective length of the cantilever beam. A parametric study is conducted on 3231 cantilever beams under uniform bending to propose an approximative formula to determine the warping effective length factor which depends on the ratio between the torsional constant of the end-plate and the warping stiffness of the beam. The small standard deviation and high coefficient of determination show a very good correlation between analytical formulas and numerical results. Numerical applications are applied to analyze some cantilever beams subjected to uniform bending to demonstrate the reliability of the proposed formula and the effects of the end-plate on the enhancement of the global stability of cantilever beams with free end restrained laterally.

Keywords:

cantilever lateral buckling; end-plate; edge stiffener; flexural-torsional buckling; warping effective length; warping effective length factor.
Reconstrucción postsísmica en el suelo de conservación ecológica de la Ciudad de México: experiencias de un asentamiento irregular
Authors: Toscana Aparicio Alejandra
Published: January 2021

El objetivo de este texto es analizar el proceso de reconstrucción tras el sismo del 19S en el barrio La Conchita del pueblo San Gregorio Atlapulco, alcaldía de Xochimilco, Ciudad de México, donde al menos 40 familias perdieron su casa. Dicho barrio es un asentamiento irregular ubicado en suelo de conservación ecológica, en particular en un área de patrimonio cultural, histórico y agrícola, condición que le impidió el acceso a la política formal de reconstrucción, por lo que ésta se dio a partir de diversas iniciativas particulares y de la sociedad civil. Mediante una investigación cualitativa basada en la recolección de testimonios de familias damnificadas y actores clave en el proceso local de reconstrucción, se observó que las condiciones de vulnerabilidad y la limitada capacidad de recuperación de la población de La Conchita son producto de una historia de marginación social, la cual es común en los asentamientos irregulares, en donde se asienta población excluida de las políticas de desarrollo. El estudio permitió comprender y visibilizar cómo se ha vivido el desastre en un área periférica e irregular inmersa en un área de conservación y qué problemas enfrenta este tipo de asentamientos excluidos de la política oficial de reconstrucción postsísmica.
Exponential stability for a thermoelastic laminated beam with nonlinear weights and time-varying delay
Authors: Nonato Carlos , Raposo Carlos , Feng Baowei
Published: January 2021

In this paper, we study the well-posedness and asymptotic stability to a thermoelastic laminated beam with nonlinear weights and time-varying delay. To the best of our knowledge, there are no results on the system and related Timoshenko systems with nonlinear weights. On suitable premises about the time delay and the hypothesis of equal-speed wave propagation, existence and uniqueness of solution is obtained by combining semigroup theory with Kato variable norm technique. The exponential stability is proved by energy method in two cases, with and without the structural damping, by using suitably sophisticated estimates for multipliers to construct an appropriated Lyapunov functional.
Characterisations of variant transfinite computational models: Infinite time Turing, ordinal time Turing, and Blum–Shub–Smale machines
Authors: Welch Philip
Published: January 2021

We consider how changes in transfinite machine architecture can sometimes alter substantially their capabilities. We approach the subject by answering three open problems touching on: firstly differing halting time considerations for machines with multiple as opposed to single heads, secondly space requirements, and lastly limit rules. We: 1) use admissibility theory, [Formula: see text]-codes and [Formula: see text]-reflection properties in the constructible hierarchy to classify the halting times of ITTMs with multiple independent heads; the same for Ordinal Turing Machines which have On length tapes; 2) determine which admissible lengths of tapes for transfinite time machines with long tapes allow the machine to address each of their cells – a question raised by B. Rin; 3) characterise exactly the strength and behaviour of transfinitely acting Blum–Shub–Smale machines using a Liminf rule on their registers – thereby establishing there is a universal such machine. This is in contradistinction to the machine using a ‘continuity’ rule which fails to be universal.

Authors: Wu Min , Xu Junhua , Zhu Shanshan , Lei Jinzhi , Gao Jie
Published: January 2021

Analysis of single-cell RNA sequencing (scRNA-seq) data is often complicate due to the sparsity and high data dimensionality. In this work, we proposed Fuzzy C-means based linear stable-exponential distribution (LSED) model for analyzing scRNA-seq count data of chronic myeloid leukemia (CML) patients. We propose pipelines stages for analysis in which noisy and inconsistent data form sequencing is removed during data preprocessing, this process data then form the cluster of gene feature using fuzzy c-means (FCM) clustering, relevant features are extracted during feature extraction approach. These extracted features are then fed into LSED model in order to difference feature data of gene expression. Finally we evaluate the performance for proposed analysis model based on parameter estimation, distribution comparison and parameter analysis. From the result analysis it was observed that proposed analysis model parameter reflect change in condition of patient more effectively as well as this model fits difference data of gene expression in more better way in comparison to Cauchy and stable distribution. Additional, the results of Gene-set enrichment analysis specify the affinity of proposed model can replicate the distinct enhancement of BCR-ABL+ stem cell as well as BCR-ABL- stem cells. Significantly, proposed FCM based LSED analysis model studies CML from the perspective of statistical models, which present a new sight for CML scientific research.
Fuzzy coordination through measure information sharing of multi-robot system: A case study
Authors: Dai Xuefeng , Wang Jiazhi , Li Dahui , Wang Yanchun
Published: January 2021

Multi-robot systems have many potential applications; however, the available results for coordination were based on qualitative information. Fuzzy logic reasoning has a feature of human being thinking, so a novel coordinated algorithm is proposed. The algorithm utilizes sharing sensing information of rooms and semantic robots to coordinating robots in a structured environment exploration. The approach divides all teammate robots into two classes according to robot exploration performance, and divides rooms into large, medium and small ones according to estimations of the individual areas. On the purpose of minimizing exploration time of the system, the reasoning coordination assigns large room to good performance robot, and vice versa. A parameter update law is introduced for fuzzy membership functions. Finally, the results are validated by computer simulations for a structured environment.

Parameter design of biped robot motion system based on multi-objective optimization
Authors: Leng Xiaokun , Piao Songhao , Chang Lin , He Zhicheng , Zhu Zheng
Published: January 2021

In recent years humanoid robots have been widely used in toy, performance, education and other service industries, but most biped robots walk slowly and have poor stability. The reason is that the driver parameters of the robot cannot properly match the walking gait algorithm, and the insufficient performance of the robot driver leads to the poor motion capability of the robot. In this paper, the optimization design process of biped robot parameters is studied and expounded, and its motion capability is improved by optimizing the driving parameters of the robot. Firstly, the contradiction between walking speed, stability and driver performance of biped robot is analysed. The performance evaluation functions of the three are further established, and the optimal parameter design to a certain extent is realized based on the multi-objective optimization method. Finally, combining with the physical simulation engine, the design parameters are simulated and checked, and the robot design process is completed through the guidance of simulation results.
Probabilistic hesitant fuzzy TOPSIS emergency decision-making method based on the cumulative prospect theory
Authors: Sha Xiuyan , Yin Chuancun , Xu Zeshui , Zhang Shen
Published: January 2021

In order to fully consider the decision-maker’s limited rationality and attitude to risk, this paper constructs the probabilistic hesitant fuzzy TOPSIS emergency decision-making model based on the cumulative prospect theory under the probabilistic hesitant fuzzy environment. Aiming at the problem of missing probabilistic information in the probabilistic hesitant fuzzy element, a new complement scheme is proposed. In this scheme, the weighted average result of the original data information is used to complement, and the original data information is retained to a large extent. Then this paper proposes several probabilistic hesitant fuzzy distance measures based on Lance distance. The decision reference point is constructed by the probabilistic hesitant fuzzy Lance distance, which overcomes the influence of the extreme value on the decision-making result, and defines the value function based on the probabilistic hesitant fuzzy Lance distance. In view of the fact that the attribute weights are completely unknown, the probabilistic hesitant fuzzy exponential entropy is constructed by using the actual data, and the attribute weights of different prospect states are obtained. Aiming at the problem that attribute weights of different prospect states have different effects on the cumulative prospect value, the expression of the cumulative prospect value is improved. The improved closeness coefficient of the TOPSIS method is used to order the emergency schemes. Finally, the new method is applied to the emergency decision-making case of a sudden outbreak of epidemic respiratory disease. The results show that the contrast of the new method is obvious, which is conducive to distinguish different schemes. The new method is more suitable for the complex and changeable emergency decision-making field.

A new measure of indeterminacy for uncertain variables with application to portfolio selection
Authors: Liu Jin , Xie Jinsheng , Ahmadzade Hamed , Farahikia Mehran
Published: January 2021

Entropy is a measure for characterizing indeterminacy of a random variable or an uncertain variable with respect to probability theory and uncertainty theory, respectively. In order to characterize indeterminacy of uncertain variables, the concept of exponential entropy for uncertain variables is proposed. For computing the exponential entropy for uncertain variables, a formula is derived via inverse uncertainty distribution. As an application of exponential entropy, portfolio selection problems for uncertain returns are optimized via exponential entropy-mean models. For better understanding, several examples are provided.

Este trabalho teve como objetivo avaliar a aplicação das geotecnologias na construção de Modelos Digitais de Superfície (MDS) para dois sangradouros localizados na praia do Cassino, município do Rio Grande, RS. O emprego das geotecnologias, como a aeronave remotamente pilotada (ARP) e o receptor GNSS-RTK, resultou na construção de seis MDS, dois para cada dia de voo, dos canais com resolução espacial entre 5,05 cm e 5,26 cm. Ressaltamos que o uso das técnicas de geoprocessamento e a aplicação da ARP são de grande valor no aprimoramento de estudos sobre as zonas costeiras e os sangradouros do Balneário Cassino.
Palavras-chave: geotecnologias, geomorfologia costeira, sangradouros, drone.

O trabalho teve como objetivo identificar e mapear os conflitos ambientais que abrangem a comunidade pesqueira artesanal na zona costeira brasileira, de forma a proporcionar maior visibilidade aos atores sociais, vitimizados pela desigualdade e injustiça ambiental, em favor de projetos econômicos. Para esta análise foram utilizados os dados do Mapa de Conflitos e Injustiça Ambiental em Saúde no Brasil elaborado pela Fiocruz, de forma a sistematizar uma proposta metodológica focada nos conflitos presentes nos estados costeiros do país e relacionados com a pesca artesanal. Os resultados apontam que os estados da Bahia (14), Ceará (12) e Rio de Janeiro (9) têm o maior número de conflitos na pesca. Entre as principais atividades econômicas geradoras de conflito na pesca artesanal destacam-se a indústria química e de petróleo/gás (35,62%), os portos e estaleiros (32,88%) – predominantes nas regiões Sul e Sudeste –, o turismo (30,14%) e as atividades pesqueiras e de carcinicultura (24,66%) – com maior incidência nas regiões Norte e Nordeste do país.

Published: January 2021

A zona costeira, área de extrema dinamicidade devido à interação entre os sistemas marinhos e continentais e aos também fenômenos climáticos, tem passado por consequentes alterações em decorrência das mudanças climáticas cada vez mais recorrentes e severas, implicando diretamente na linha de costa, seja na forma de erosão, seja na progradação. Dessa forma, utilizando-se das metodologias associadas às técnicas de geoprocessamento, foi possível verificar que nos últimos 13 anos o trecho de praia que compreende a Resex da Prainha do Canto Verde, localizada no litoral leste do Ceará, apresentou taxas de erosão que variamentre -4,14 m/ano e -2,33 m/ano (EPR) e de -3,66 m/ano a -1,77 m/ano (LRR). Em termos totais, isso representa um recuo da linha de costa que variou entre pouco mais de 50 m, no máximo, e mínimo de 23 m de acordo com as estatísticas utilizadas pela extensão DSAS.

O presente artigo tem como objetivo entender as (des)razões que fundamentaram a interdição da doação de sangue por homens-que-fazem-sexo-com-homens (HSH) e suas parceiras por 12 meses, o que, na prática, fez-se por definitiva, a partir das teses levantadas no julgamento da ADI 5543/DF no Supremo Tribunal Federal. A metodologia utilizada é desenvolvida a partir de uma pesquisa exploratória, bem como de análise de conteúdo, considerando a necessidade verificar eventuais (in)compatibilidades e (des)conformidades constitucionais, veladas nas formas que revestem a atividade interpretativa do Supremo Tribunal Federal, à luz da sociologia reflexiva. Conclui que a proibição da doação de sangue por HSH não se sustenta quando frente aos princípios da proporcionalidade e da razoabilidade, além de consistir em grave desrespeito aos direitos humanos homoafetivos.

The purpose of the study was to investigate the influence of supportive and directive leadership style on employee job satisfaction in commercial banks in Kenya. The study adopted positivism research philosophy to guide the study and limited itself to descriptive correlational research design to analyze and provide responses to the research questions. The research design was preferred because it allows description and comparison of characteristics of populations based on data collected from samples through questionnaires. The target population of the study was 15,030 employees in all the 43 commercial banks licensed to operate in Kenya as of June 2018. Using stratified sampling technique, the study drew a sample size of 386 employees reporting to middle level managers. Data was collected by means of a questionnaire and analyzed using descriptive and inferential statistics, which included factor analysis, correlational analysis, chi-square, one-way analysis of variance (ANOVA), and regression analysis using Statistical Package for Social Sciences (SPSS) version 20 and Windows’ Microsoft excel programs.From the findings of multiple linear regression analysis, it was established that directive leadership style had a positive and significant relationship with employee job satisfaction, R2 = .228, F(1, 362) = 53.396, p < .05; β = .454, p < .05. The results from multiple linear regression analysis also showed that supportive leadership style positively and significantly predicted employee job satisfaction, R2 = .603, F(1, 366) = 278.269, p < .05; β = .716, p < .05. In addition, the study tested the moderating influence of environmental contingency factors and was confirmed that environmental contingency factors significantly moderated the relationship between path-goal leadership style and employee job satisfaction, R2=0.090, F(5,364) = 35.04, p < .05; β= 0.229, p<.05.The study makes a contribution to the literature of the influence of directive and supportive leadership styles from Kenyan commercial banks’ perspective and adds an impetus to employees, management and policymakers to address issues that are impeding employee job satisfaction. The future researchers should include all bank employees in their study to determine the influence of directive leadership style and supportive leadership style on employee job satisfaction.

Published: January 2021

Current environmental crises make us vulnerable to disasters and tragedies. With environmental problems mounting up, unless immediately addressed with care, we are surely to be doomed. The objective of this qualitative study is to figure out the level of concern as well as understanding that the organizations have on green aspect of Human Resource Management (Green HRM) and also to get an idea about the real implications of green HRM practices. The aim is to interview HR managers from different organizations, manufacturing in nature as Green concept mostly affect this particular area the most and to get a clear picture about their perspectives on Green HRM practices. HR managers from 10 organizations were interviewed, where the respondents were asked questions for 45-60 minutes by a team of 4-5 members. The questions asked during the interview were probed and found that most of the organizations although seemed well informed about the importance of going green concept, but only a few practice it through their actions in day to day HRM functions. The prime limitation is the size of the sample, an extensive study could be carried out in future. The signal from this study is very evident that organizations are familiar with green concepts, but they lack the motivation and top management support as well as monitoring to put this green concept into action for passing on a sustainable, and healthier environment for the generations to come. This study provides an extensive review of literature where the Green HRM practicality examination was needed to be applied into a climate change victim region and the paper successfully finds out the extent of HR managers perspectives and their actions and also provides guidelines to the manufacturing industry and policy makers.
