Authors: Tomonaga Yuki , Zens Kyra Denise , Lang Phung , Born Rita , Schwenkglenks Matthias , And the Swiss Sentinel Surveillance Network
Published: September 2021

BACKGROUND: The incidence of influenza and influenza-like illnesses in Switzerland is generally high. Although related direct medical costs can be substantial, especially if hospitalisations occur, several studies suggested that indirect costs due to the loss of productivity may represent an even higher economic burden. The aim of this study was to assess the costs arising from lost productivity due to influenza and influenza-like illnesses in Switzerland.
METHODS: Analyses were based on data collected in 2016 and 2017 by the Swiss Sentinel Surveillance Network of the Swiss Federal Office of Public Health (SFOPH). The available information covered details on the physicians collecting the data, patients’ characteristics, symptoms, treatments, and inability to work (in terms of physician-recorded workdays lost for own sickness or caregiving). The cost of lost productivity, estimated using the human capital approach, was calculated as the number of workdays lost due to influenza-like illnesses multiplied by the mean salary for one working day. Salary differences across sex, age and region were considered. Extrapolation to the national level was performed by adjusting for the size of the Swiss population, the age and sex distribution, the regional distribution, the number of Sentinel general physician contacts and the specialisation of the physician.
RESULTS: At the Swiss national level, the estimated total yearly number of cases of inability to work due to influenza and influenza-like illnesses was 101,287 in 2016 and 86,373 in 2017. In subgroups defined by year, gender, region and age class, numbers of cases per 100,000 inhabitants ranged from 12 to 2396. The total number of workdays lost in Switzerland, considering degree of employment and visit day, were estimated to be 324,118 in 2016 and 278,121 in 2017. The number of workdays lost was generally higher in men (53.7% of the total in 2016 and 55.6% of the total in 2017) than women. The estimated total costs due to inability to work, calculated using a human capital approach and including the caregiving costs, were CHF 115 million in 2016 and CHF 103 million in 2017, equivalent to CHF 1.4 million per 100,000 inhabitants.
CONCLUSION: The costs of lost productivity due to influenza and influenza-like illnesses in Switzerland are substantial and may vary considerably between different years, regions and age classes. As the present analyses could not consider all causes of lost productivity (e.g., short-term inability to work not requiring a physician consultation, hospitalisations, early retirement, premature death), the total indirect costs due to influenza or influenza-like illnesses can be expected to be higher than the presented estimates.

The present study was performed to compare the expression of sperm proteins, i.e. triosephosphate isomerase (TPI) and acrosin binding protein (ACRBP) and seminal plasma proteins, i.e. glutathione peroxidase 5 (GPX5) and fibronectin 1 (FN1), in boar semen with good, moderate and poor freezability. The study was conducted by determining the protein contents in 32 sperm samples and 38 seminal plasma samples of semen. The ejaculated semen was divided into two portions: the first portion was centrifuged to separate the pellet of sperm from the seminal plasma and the second portion was cryopreserved. After thawing, the ejaculates were classified into three groups according to their post-thawed sperm motility: good (60.2 ± 1.7%), moderate (29.3 ± 2.0%) and poor (16.6 ± 2.2%) freezabilities. The expressions of GPX5 and FN1 in seminal plasma and TPI and ACRBP in sperm were determined using Western blot analysis. It was found that, for sperm proteins, the level of TPI was negatively correlated with the post-thawed total sperm motility (r = -0.38, P = 0.029). For seminal plasma proteins, the level of FN1 in the seminal plasma was positively correlated with the post-thawed total sperm motility (r = 0.37, P = 0.021) and progressive motility (r = 0.39, P = 0.016). The expression of GPX5 was not correlated with any of the frozen–thawed sperm qualities (P > 0.05). In conclusions, boar semen containing a high level of FN1 in seminal plasma has better freezability. Frozen–thawed sperm motility was positively correlated with the level of FN1 in boar seminal plasma and negatively correlated with TPI in boar spermatozoa.

Published: September 2021

Apesar das políticas de inclusão priorizarem a matrícula dos estudantes surdos na escola comum, o movimento surdo reivindica a criação e a manutenção das Escolas de Surdos. Observa-se a necessidade de pesquisar como está sendo realizado o ensino e a aprendizagem nesses dois espaços, para que os estudantes surdos sejam melhor atendidos. O objetivo geral deste trabalho é analisar como o ensino de Geografia está sendo realizado na Escola Comum e nas Escolas de Surdos, pelo uso da pesquisa qualitativa. Foram aplicados questionários com 42 estudantes surdos do 9º ano do Ensino Fundamental, no âmbito de cinco Escolas de Surdos, localizadas nos estados de Minas Gerais, São Paulo, Goiás e no Distrito Federal. O estudo verificou que a maioria dos estudantes pesquisados considerou que a aprendizagem nas Escolas de Surdos é ótima, justificando que os professores se comunicam e ministram aulas em Libras, além de utilizarem recursos didáticos que exploram a visualidade, como o computador, projetor multimídia, TV, Internet, mapas, imagens, dentre outros. Já na escola comum, as práticas pedagógicas realizadas pelos professores de Geografia são direcionadas para os estudantes ouvintes e não incluem os surdos em suas especificidades linguísticas e culturais. Concluiu-se que o ensino de Geografia realizado na Escola Bilíngue de Surdos, com professores de Geografia formados na área, proficientes em Libras e com conhecimentos metodológicos para surdos, é realizado de modo satisfatório.

As políticas públicas de educação especial desenvolvidas no Brasil, para a legalização do direito à educação das pessoas com deficiência, são expostas no decorrer do artigo. Nesse contexto, analisou-se também, a perda de direitos e o processo de reestruturação da Política Nacional de Educação Especial na Perspectiva da Educação Inclusiva. Com o embasamento teórico da Psicologia Histórico-Cultural e da Pedagogia Histórico-Crítica, as quais fundamentam-se no Materialismo Histórico-Dialético, método de abordagem utilizado, este trabalho constitui-se em uma pesquisa qualitativa com revisão bibliográfica e análise documental. Assim, a escolarização dos alunos com deficiência segue sendo ofertada na escola comum, ainda que as possibilidades de aprendizagem aconteçam em meio a condições que nem sempre são as mais adequadas ao ensino e ao atendimento das necessidades dos alunos. A precariedade da educação pública ocorre decorrente do baixo investimento estatal e de políticas públicas mínimas, em razão da desigualdade criada pelo capitalismo.

Este trabalho tem como objetivo analisar como os professores de Geografia do Ensino Fundamental II aplica as leis federais 10.639/2003 e 11.645/2008 em sala de aula. Estas leis incluíram oficial no currículo oficial da Rede de Ensino a obrigatoriedade da temática “Histórias e Culturas Afro-Brasileiras e Indígenas”.  O estudo terá caráter qualitativo, com ênfase na Análise de conteúdo das respostas dos professores de Geografia do Ensino Fundamental II de escolas públicas da cidade de Uberlândia, Minas Gerais, que participaram da pesquisa. As leis federais 10.639/03 e 11.645/08 se propõe a refletir, atribui à discussão e reflexão acerca da história, da memória e da luta dos povos negros e indígenas socialmente excluídos ao longo do processo histórico do Brasil, até os dias atuais. De modo geral percebe-se que os professores têm avançado em relação às leis, como também o interesse de trabalhar com a temática, por isso a necessidade de formação de professores para aproximação e desmitificação para com os conhecimentos da cultura indígena, africana e afro brasileira. Construir uma identidade positiva e de afirmação social do indígena e do negro é necessário. A escola deve se apropriar de estratégias educativas de combate às formas de discriminação étnica, inicialmente a partir de uma formação dos profissionais da educação, e inclui-los nas ações pedagógicas que forneçam aos alunos a oportunidade de valorizar, conhecer, vivenciar a cultura negra e indígena. A Geografia a partir de suas categorias como lugar, paisagem, território e região, tem condições de realizar uma docência antirracista, mas para isso são necessários a formação inicial e continuada, e também de livros e outros materiais didáticos na mesma perspectiva.
Solidão na Comunhão: as lições da Vida Monástica em tempos de isolamento
Authors: Peixoto Cristiano Holtz
Published: September 2021

A pandemia da COVID-19 mudou radicalmente os modos de relacionamento de todas as pessoas. Embora se percebessem traços de individualismo no comportamento humano, há pouco tempo era impensável que fosse possível, ou mesmo necessário, o mundo inteiro se isolar para evitar a rápida disseminação do coronavírus. Este artigo visa mostrar como a Vida Monástica, que tem como uma de suas características o afastamento da sociedade, tem a contribuir para a reflexão teológica do momento atual a partir de conceitos-chave praticados e refletidos há muitos séculos, a saber, a solidão e a comunhão. Longe de se distanciar de forma alienada do mundo, os monges e monjas vivem uma profunda comunhão com a humanidade, e a sabedoria multissecular vivida nos claustros pode ajudar a iluminar o presente contexto. Refletindo sobre textos antigos e novos, é possível oferecer uma ajuda concreta àqueles que vivem atualmente, de forma compulsória, um modo de vida que monges e monjas abraçaram como resposta ao chamado de Deus neste modo de vida específico.

Published: September 2021

The aim of this research was to determine relationships among forage yield and its some characters in Narbonne vetch cultivars sown in early spring at subtropical conditions. This investigation was conducted between 2016-2018 years at Tekirdağ Namık Kemal University, Faculty of Agriculture, Field Crops Department Research and Experimental Area in randomized complete block design with three replications. Three Narbonne vetch (Bozdağ, Dikili and Özgen) cultivars were used. The plant height, number of branches per plant, stem diameter, number of leaves per plant were determined in ten plants. The plant height, number of branches per plant, stem diameter, number of leaves per plant, herbage and hay yields ranged from 40.75-43.09 cm, 1.67-2.72, 5.70-6.57 mm, 10.27-13.73 t ha-1 and 2.28-2.89 t ha-1, respectively, in Narbonne vetch cultivars. A statistically significant and positive relationships were determined between herbage yield and hay yield, between stem diameter and herbage yield and between stem diameter and hay yield. The correlation coefficients analysis showed that the strongest effective trait on herbage yield in Narbonne vetch was the stem diameter. Stem diameter trait can be considered as the primary selection criteria for improving herbage yield in Narbonne vetch at early spring sowing in similar ecological conditions

It’s Not Just a Pay Gap: Quantifying the Gender Wage and Pension Gap at a Post-Secondary Institution in Canada
Authors: Smith-Carrier Tracy , Penner Marcie , Cecala Aaron , Agócs Carol
Published: September 2021

What is the impact of the gender pay gap in academia over the course of a career and retirement? To quantify this impact, we used a Canadian post-secondary institution as a case study and simulated the effects of the reported difference in salary across multiple academic career trajectories. A starting wage gap of less than $9,000 resulted in a $300,000–$400,000 gender wage gap over the course of a career, and a further $148,000–$259,000 gender pension gap, for a total gender pension and wage gap of $454,000–$660,000, depending on the rank achieved. Thus, focusing on gender gaps in salary alone leads to a substantial underestimation of the long-term effects of the gender gap.

Authors: Nangih Efeeloo , Wali Samuel Chikwuchehia , Anyanwu Peggy Oluchi
Published: September 2021

The accounting policy adopted by an enterprise, together with the level of approximations done by the management in financial statements, could either enhance or impair their relevance and reliability, and by extension, the credibility of financial decisions made by users of such reports. This is because financial statements portray the financial position and performance of entities. This study assesses the influence of management’s choice of accounting policy and accounting approximations in financial statements on the quality of financial reports of Small and Medium Enterprises in Nigeria. The study was anchored on the Stakeholders’ theory. The study also adopted the survey design approach. Data were mainly collected through the questionnaire and was analyzed using descriptive statistics and regression techniques. Findings revealed that wrong approximations may affect the quality of financial reports, together with other factors.  It was recommended that management of small and medium enterprises should adhere to the provisions of accounting standards when designing their accounting policies and in their judgements/approximations; in order to reduce material errors and enhance the quality of their financial report.

Authors: Piñerúa-Gonsálvez Jean Félix , Zambrano-Infantino Rosanna del Carmen , Alberto Alberto , Sulbaran Mariseli , Camaray Noheltriz
Published: September 2021

Introduction: Adequate bowel preparation is one of the most important factors related to the yield of colonoscopy. Low-quality bowel preparation has been associated with lower adenoma detection rates and increased healthcare expenses. Bowel preparation is a major impediment to undergo colonoscopy since it is perceived as an unpleasant experience by patients. Objective: This study was aimed to assess tolerance and acceptability of the bowel preparation using either polyethylene glycol (PEG) or mannitol solution. Materials and methods: We enrolled 140 patients with indications of screening for colorectal cancer or with suspected large bowel diseases. They received either mannitol solution or PEG as bowel preparation. Patients were asked to fill a questionnaire about the bowel preparation experience. Results: Patients perceived more burdensome the preparation with PEG than mannitol for the variables nausea overall experience, post-procedure discomfort, disagreeable flavor, volume ingested and cost (p<0.05). A similar tolerance was reported for abdominal pain, bloating and anal irritation (p>0.05). The acceptability was 82.9% and 71.4% in the Mannitol group and in the PEG group, respectively (p=0.10). Conclusion: Acceptance of the bowel preparation between mannitol solution and PEG was comparable. However, mannitol was bettertolerated by the patients in regard to most of the evaluated items.

Authors: Alrub Ahmad Abu , Awwad Tahir Abu , Al-Saadi Emad
Published: September 2021

Purpose: The given study looks into forecast accuracy of a traditional ARIMA model while comparing it to Autoregressive Neural Network (AR-NN) model for 984 trading days on EURO STOXX 50 Index.

Methodology: A hybrid model is constructed by combining ARIMA model and feed-forward neural network model aiming to attain linear and non-linear price fluctuations. The study also incorporates the investigation of component stock prices of the index, that can be selected to improve the predictability of the hybrid model. 

Findings:The reached ARIMA (1,1,3) model showed higher scores than AR-NN model however integrating selected exogenous stock prices from the index components gave much notable accuracy results. The selected exogenous stocks were extracted after conducting PCA and model scores were compared via MAPE and RMSE.

Unique contribution to theory, practice and policy: The major contribution of this work is to provide the researcher and fnancial analyst a systematic approach for development of intelligent methodology to forecast stock market. This paper also presents the  outlines of proposed work with the aim to enhance the performance of existing techniques. Therefore, Empirical analysis is employed along with a hybrid model based on a feed-forward Neural Network. Lesser error is attained on the test set of Index stock price by comparing the performance of ARIMA and AR-NN while forecasting. Hence, The components of extracted Index stock price like exogenous features are added to make an influence from the AR-NN model.
INFLUENCE OF ELECTRONIC WASTE MANAGEMENT SYSTEMS IN KENYA. A CRITICAL LITERATURE REVIEW.
Authors: NGETHE DANSON
Published: September 2021

Purpose: There is a variety of electronic waste found in the country ranging from computers, cellular phones, televisions sets, refrigerators, and entertainment electronics amongst others. The general objective of the study was access the influence of electronic waste management systems in Kenya. A critical literature review

Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps.

Findings: The study concludes that the methods employed in e-waste management were still inadequate. Most importers disposed of the undistributed computers and mobile phone at a discounted price to retailers and consumers. Very few importers used extended ·producer responsibility. In addition, majority of the end users used auctioning as a method of e-waste management.

Recommendations: The study suggested that there is a need for the manufacturer to design a system which provides incentives to consumers to bring back products to the appropriate collection points. The incentives can be used in the beginning of the collection scheme as a way of advertising the scheme and when the scheme is well established the manufacturer can review and determine if there is need for incentives.

IMPACT OF ENVIRONMENTAL NOISE ON INDIVIDUAL HEARING PROBLEMS. A CRITICAL LITERATURE REVIEW
Authors: OLUBWA JAMES
Published: September 2021

Purpose: A normal person cannot perceive sound to its minimum level of 0 dB or the sound of rustling leaves. Persons with excellent hearing capabilities can receive sound levels as low as 15 dB. On the higher end, sound levels that exceed 85 dB can cause damage as bad as permanent hearing damage. The period spent around loud sound determines the extent of damage that will occur. The calmer the sound, the longer one can withstand it without any alarming effect. The general objective of the study was to access the impact of environmental noise on individual hearing problems. A critical literature review

Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps.

Findings: The study concludes that safety practices that can assist in preventing hearing losses and other harmful effects call for personal, physician, and administrative engagement. Administratively, employers have an obligation to provide safety devices that prevent hearing loss or impairment. Employers should provide personal protective equipment to abate noise levels and that employers should give all employees an opportunity select hearing protectors that vary from entire head enclosures, canal caps, earplugs, to ear mugs.

Recommendations: The study suggested that that personal hearing protective devices use should be enforced through education and inbuilt administrative mechanisms. Only consistent long term use of prevention produces positive impact. It is also recommended that utilization of safety strategies like shift rotations, leave scheduling, acoustic sound proofing of offices, quiet machinery and other strategies be enhanced through deliberate administrative effort.

The Effect of Landscape Trees on Residential Property Values of Six Communities in Cincinnati, Ohio
Authors: Dimke Kelley , Sydnor T. Davis , Gardner David
Published: September 2021

The value of the urban forest as a component of the urban environment is significant. Trees provide both environmental and social benefits to urban dwellers. In many cities, financial support for urban forestry is on the decline. The objective of this research was to evaluate the impact trees have on property values of six communities (Bond Hill, Carthage, Clifton, Hyde Park, Kennedy Heights, and North Avondale) of varying socioeconomic levels in Cincinnati, Ohio, U.S. Tax assessor records were obtained for property sales between the years 2000 and 2005. One hundred sites were randomly selected from each of the six communities. Data were collected from each site during the winter as well as the summer months. Dominant genus, caliper of dominant genus, estimate of tree cover, and overall property maintenance were recorded. The hedonic method was used for this analysis. The average (mean) effect of tree canopy across all six communities was an increase of approximately USD $780 per one percent increase in tree cover. The mean sale price across the 600 sites was $188,730; the mean canopy cover was 25.8%. This indicates the average value of tree canopy is $20,226 or 10.7% of the sale price of the home.

In 2004, Mississippi State University researchers determined the status, needs, and knowledge levels of Mississippi’s community leaders and communities relative to urban and community forestry benefits, programs, funding opportunities, and program implementation. As a result, this project’s goals were to build on past research and identify trends for past and current involvement and future interest levels among Mississippi’s small (<2,000 people) to large (>10,000 people) communities for urban and community forestry programs and assistance. This current effort revisited these communities, previously surveyed in 2004, and highlighted changes in knowledge levels and various activities and programs undertaken. A mail survey was sent to 293 Mississippi communities with 163 surveys returned for a response rate of 55.6%. In general, communities responding indicated that a sizable number of officials have increased their awareness or interest in urban and community forestry. Communities that wanted to establish programs the most again cited a lack of funding as the reason for not initiating projects or sustaining existing programs. Greater effort in disseminating information on funding opportunities was seen as necessary, given that most Mississippi communities were only aware of a few national programs. Participation in statewide or local urban forestry programs and activities was minimal. The authors’ previous study found that without quality, updated information on urban and community forestry and reliable funding, communities are limited in undertaking systematic planning and associated programs utilizing arboreal resources. Good information distribution, which has improved, and reliable funding are still limiting communities in undertaking systematic planning and associated urban and community forestry programs.
Identifying Common Practices and Challenges for Local Urban Tree Monitoring Programs Across the United States

Published: September 2021

Urban forest monitoring data are essential to assess the impacts of tree planting campaigns and management programs. Local practitioners have monitoring projects that have not been well documented in the urban forestry literature. To learn more about practitioner-driven monitoring efforts, the authors surveyed 32 local urban forestry organizations across the United States about the goals, challenges, methods, and uses of their monitoring programs, using an e-mailed questionnaire. Non-profit organizations, municipal agencies, state agencies, and utilities participated. One-half of the organizations had six or fewer urban forestry staff. Common goals for monitoring included evaluating the success of tree planting and management, taking a proactive approach towards tree care, and engaging communities. The most commonly recorded data were species, condition rating, mortality status, and diameter at breast height. Challenges included limited staff and funding, difficulties with data management and technology, and field crew training. Programs used monitoring results to inform tree planting and maintenance practices, provide feedback to individuals responsible for tree care, and manage tree risk. Participants emphasized the importance of planning ahead: carefully considering what data to collect, setting clear goals, developing an appropriate database, and planning for funding and staff time. To improve the quality and consistency of monitoring data across cities, researchers can develop standardized protocols and be responsive to practitioner needs and organizational capacities.
Methodology for Spatial Analysis of Municipal Street Tree Benefits
Authors: Cowett F.D.
Published: September 2021

Street trees comprise a fraction of the urban forest; however, due to their public function, the benefits they provide to urban residents have received particular attention from researchers. Spatial analyses of street tree benefits have been based on street tree counts that do not account for differences in tree species and size that in turn impact leaf surface area from which most benefits are derived. The United States Forest Service’s i-Tree Streets software program quantifies street tree benefits and does account for differences in tree species and size, but is not a Geographic Information Systems program and does not facilitate the spatial analysis of street tree benefits. This paper proposes a methodology for analyzing the spatial distribution of street tree benefits employing measures based on i-Tree Streets. Providence, Rhode Island, U.S., serves as a case study.
Rancière’nin temel pedagojik düşüncesi
Authors: Duman Musa
Published: September 2021

Fransız filozof Jacques Rancière Cahil Hoca’da “açıklayıcı öğretmen” modeline karşı çıkar. Öğretmenin merkez-dışı edildiği bu pedagojik programın amacını Rancière “zihinsel özgürleşme” olarak ifade etmektedir. Bu özgürleşme gayesi öğrencinin henüz eğitim sürecinde iken bağımsız bir bilgi ve araştırma öznesine dönüşmesini ve eğitimin de buna göre tasarlanmasını şart koşmaktadır. Zihinsel özgürleşme burada yalnızca öğrencinin değil aynı zamanda öğretmenin de özgürleşmesini içerir. Bu özgürleşmeyi yöneten pratik postülat (ya da pratik aksiyom), Rancière’e göre, “zekâların eşitliği” ilkesi olmalıdır. Hiyerarşilerin ortadan kalktığı eşitlikçi bir toplumsal realite önce eşitlikçi bir epistemolojik sahanın tesisinden geçmektedir. Cahil hocanın (öğretmen) işlevi bu noktada iki-boyutludur; tamamen öğrencinin zekâsını bağımsız ve aktif kullanabilmesine dayanan bir öğrenme sürecinin (yani, araştırma süreci olarak öğrenme sürecinin) önünü açmak ve aynı zamanda bu yolla eğitimin eşitsizlikçi ideolojik girdilerini minimize etmektir. Yine de Rancière’nin yaklaşımında zihinsel özgürleşme idealinin belirleyici bir rol oynamasının bir negatif sonucu vardır; bireysel çalışma düşüncesi, bireyin güçlerini yalnızca kendi bağımsız çalışması ile keşfedebileceği ve aktive edebileceği düşüncesi, tek-yanlı olarak vurgulanmaktadır. Buna paralel olarak diyalog ve birlikte çalışmanın (hem öğrenci ile öğrenci hem de öğrenci ile öğretmen arasında) eğitsel rolü hakettiği ilgiyi görmemektedir.
LEXICO E ONIONÍMIA: um estudo de nomes próprios de cachaças da cidade de Salinas-MG
Authors: Alves de Souza Pereira Mauricio
Published: September 2021

Os estudos do léxico, isto é, das palavras que compõem uma língua, permitem-nos compreender o sistema de vida e as práticas culturais dos falantes. Nesse sentido, a Onomástica se relaciona com os estudos lexicais, visto que, ao estudar os nomes próprios, criados pelos seres humanos, é possível identificar motivações de ordem cultural. Dito isso, o objetivo deste trabalho é realizar apontamentos teóricos acerca de uma das subáreas da Onomástica: a Onionímia – responsável pela análise de nomes próprios comerciais –, e analisar, dentro do léxico dos moradores de Salinas/MG, o processo de nomeação de três cachaças produzidas na região: Puluzinha, Primadela e Caladinha. Para isso, ancorar-nos-emos nas pesquisas acerca do léxico e da onomástica, como Guérios (1973) e Neumeier (2008).
A Fragmentation Region-based Skyline Computation Framework for a Group of Users

Published: September 2021

Skyline processing, an established preference evaluation technique, aims at discovering the best, most preferred objects, i.e. those that are not dominated by other objects, in satisfying the user’s preferences. In today’s society, due to the advancement of technology, ad-hoc meetings or impromptu gathering are becoming more and more common. Deciding on a suitable meeting point (object)for a group of people (users) to meet is not a straightforward task especially when these users are located at different places with distinct preferences. A place which is close by to the users might not provide the facilities/services that meet all the users’ preferences; while a place having the facilities/services that meet most of the users’ preferences might be too distant from these users. Although the skyline operator can be utilised to filter the dominated objects among the objects that fall in the region of interest of these users, computing the skylines for various groups of users in similar region would mean rescanning the objects of the region and repeating the process of pair wise comparisons among the objects which are undoubtedly unwise. On this account, this study presents a region-based skyline computation framework which attempts to resolve the above issues by fragmenting the search region of a group of users and utilising the past computed skyline results of the fragments. The skylines, which are the objects recommended to be visited by a group of users, are derived by analysing both the locations of the users, i.e. spatial attributes, as well as the spatial and non-spatial attributes of the objects. Several experiments have been conducted and the results show that our proposed framework outperforms the previous works with respect to CPU time.
