Advancing the MPD Influx Management Envelope IME: A Comprehensive Approach to Assess the Factors that Affect the Shape of the IME
Authors: Patil Harshad , Ponder Terry Lamar , Arnone Maurizio , Hannegan Don
Published: March 2018

With increasing utilization of Managed Pressure Drilling (MPD), the industry today is leaning heavily towards the use of improved safety aspects that MPD systems exhibit. With the technological advancements to detect influxes, some of today's MPD systems are equipped with algorithms to automatically apply surface backpressure (SBP) in order to restore the overbalance while retaining the ability to circulate the small volumes of formation fluids (influx) that entered the wellbore prior to achieving the overbalance. Even when conventional well control (shutting well on BOP and circulating the kick out conventionally with the rig's choke) is used, the effectiveness of circulating a small influx using the automated MPD choke is a significant advancement for the drilling industry overall.

Some MPD systems used today have the capacity to prevent shut-in scenarios by automating the influx- handling process. The influx management envelope (IME) or MPD matrix traditionally defines the limits within which the MPD system could potentially be safely used to control and circulate these small influxes. This paper primarily proposes advancing the methodology to define the shape and size of the MPD IME defined in SPE 170684 (Mehdi 2014). It explains the changes in the shape of the IME using appropriate examples, for the various limiting factors, such as, "shoe strengths lower than RCD (Rotating Control Device) limit," "shut in scenario during circulating influx," "maximum flow rate for circulation," "mud compressibility with added backpressure," "Mud gas separator (MGS) liquid and gas handling capacity" etc. The modified shape of the resulting MPD IME is discussed systematically in this paper.

Authors: Sohrab Sayed Sartaj , El-Kafrawy Sherif Aly , Mirza Zeenat , Kamal Mohammad Amjad , Azhar Esam Ibraheem
Published: March 2018

Background:

The MERS-CoV is a novel human coronavirus causing respiratory syndrome since April
2012. The replication of MERS-CoV is mediated by ORF 1ab and viral gene activity can be modulated by RNAi
approach. The inhibition of virus replication has been documented in cell culture against multiple viruses by
RNAi approach. Currently, very few siRNA against MERS-CoV have been computationally designed and published.

Methods:

In this review, we have discussed the computational designing and delivery of potential siRNAs. Potential
siRNA can be designed to silence a desired gene by considering many factors like target site, specificity,
length and nucleotide content of siRNA, removal of potential off-target sites, toxicity and immunogenic responses.
The efficient delivery of siRNAs into targeted cells faces many challenges like enzymatic degradation and
quick clearance through renal system. The siRNA can be delivered using transfection, electroporation and viral
gene transfer. Currently, siRNAs delivery has been improved by using advanced nanotechnology like lipid nanoparticles,
inorganic nanoparticles and polymeric nanoparticles.

Conclusion:

The efficacy of siRNA-based therapeutics has been used not only against many viral diseases but
also against non-viral diseases, cancer, dominant genetic disorders, and autoimmune disease. This innovative
technology has attracted researchers, academia and pharmaceuticals industries towards designing and development
of highly effective and targeted disease therapy. By using this technology, effective and potential siRNAs
can be designed, delivered and their efficacy with toxic effects and immunogenic responses can be tested against
MERS-CoV.
Discrepancies in assessing undergraduates’ pragmatics learning
Authors: Ndayizeye Oscar
Published: March 2018

The purpose of this research was to reveal the level of implementation of authentic assessment in the pragmatics course at the English Education Department of a university. Discrepancy Evaluation Model (DEM) was used. The instruments were questionnaire, documentation, and observation. The result of the research shows that respectively, the effectiveness of definition, installation, process, and production stages in logits are -0.06, -0.14, 0.45, and 0.02 on its aspect of the assessment methods’ effectiveness in uncovering students’ ability. Such values indicate that the level of implementation fell respectively into ‘very high’,’high’, ‘low’, and ‘very low’ categories.  The students’ success rate is in ‘very high’ category with the average score of 3.22. However, the overall implementation of the authentic assessment fell into a ‘low’ category with the average score of 0.06. Discrepancies leading to such a low implementation are the unavailability of the assessment scheme, that of scoring rubric, minimal (only 54.54%) diversification of assessment methods, infrequency of the lecturer’s feedback on the students’ academic achievement, and the non-use of portfolio assessment.

Authors: Soenarto Soenarto , Amin Muhammad Mustaghfirin , Kumaidi Kumaidi
Published: March 2018

The research aimed to gain insights into the quality of four-year program vocational high school (VHS) in Indonesia compared to four-year program VHS. This research was conducted based on the school graduate standard, business sector and industrial sector (or Dunia Usaha dan Dunia Industri (DUDI)) – or the performance of the graduates and alumni (the graduates’ satisfaction). The research was conducted using Discrepancy Evaluation Model using 16 VHSs (eight four-year program VHSs and eight three-year program VHSs). The result shows that from the standpoint of the school, the graduates of the four-year program VHS are higher in quality than those of the three-year program VHS. The four-year program VHS graduates are more qualified in seven aspects: teamwork, discipline, tenacity, theoretical knowledge, confidence, creativity, and leadership. Meanwhile, using DUDI standpoint, the four-year program VHS graduates are also higher in quality than the three-year program VHS graduates. In addition, the four-year program VHS graduates are better in the quality of their discipline, tenacity, theoretical knowledge, practical skills, confidence, carefulness, creativity, and leadership. The four-year program VHS graduates have a higher level of satisfaction in terms of income than the three-year program VHS graduates. The higher quality of the four-year program VHS graduates has resulted from longer duration of the internship program (PKL) that provides them with reliable experience and skills concerning work-related problem-solving activities.

Published: March 2018

A career developed through the optimization of one’s potentials will irrevocably play a role in the development of self-identity as well as the psychological well-being of the individual. When children are introduced and allowed to explore as many career options as possible during their developmental stage, they are more likely to have a fruitful career development in the future. The preceding study showed that the career interests and knowledge of lower-grade primary students fit the Holland Career Categories: realistic, investigative, artistic, social, enterprising, and conventional (RIASEC). It was also found that the students’ career interest and knowledge levels varied, with most in the low level. This second-year study aims to expand the results of the previous study by developing the use of Quartet cards as the media of career exploration for lower-grade primary students. By using the research and development method, this study develops Quartet Career Cards into three difficulty levels: low, medium, and high. The Quartet cards media have undergone feasibility tests conducted by experts in theory and media, as well as a series of field testing consisting of preliminary, main, and operational stages among a total of 266 primary students of grades 1, 2, and 3. A revision was made on several components including the images, information, colors, font sizes, illustration styles, and card sizes. The findings show that Quartet Career Cards meet the feasibility standards for the media of career exploration

Health effects of climate change: An online survey study of participants of three massive open online courses (MOOCs) (Preprint)
Authors: Barteit Sandra , Depoux Anneliese , Sié Ali , Yé Maurice , Louis Valérie R. , Sauerborn Rainer
Published: March 2018

BACKGROUND

The impact of climate change on health, adaptation measures and health co-benefits of mitigation have not been taught as topics in conventional face-to-face courses, such as in stand-alone, accredited short courses or as modules in Masters or PhD-level courses. Educational technologies such as massive open online courses (MOOCs) have high potential to substantially accelerate the dissemination of knowledge on the nexus of climate change and health. We developed three MOOCs teaching on the link between climate change and health.

OBJECTIVE

We conducted an online survey study to evaluate instructor-to-learner interaction (ITI), instructor support (IS), instructor feedback (IF), learner-to-learner interaction (LLI), course content (CC), course structure (CS), information delivery technology (IDT), perceived effectiveness (PE), learner retention (LR), as well as self-reported learner retention (SRLR). What did participants learn? Who and how many registered from the global North and South? What was the completion rate and how does it compare to average completion rates of MOOCs? What is the impact of knowledge acquired?

METHODS

Participants of all three MOOCs were invited to a post online survey study or the three climate change and health MOOCs. The survey consisted mainly out of no/yes/other and free text questions, as well as five five-point Likert items. We collected demographic information about education, age, gender, country of origin and current place of living.

RESULTS

In total, the MOOCs had a reach of almost 7000 students worldwide. 188 students took part in the online survey, with the highest percentage of MOOC-survey participants from low-income countries. The MOOCs were seen as useful, especially with regards to their professional impact, their coverage of content and their up-to-dateness in the topic area of climate change and health. The francophone MOOC was found to have an extraordinarily high number of participants from lower-income- and low-and-middle-income countries. The primary motivation to join the MOOC was to gain knowledge and skills on the topic of climate change and health.

CONCLUSIONS

Health is a top priority for citizens worldwide, and our results show that (i) globally there is great interest in the topic of climate change and health and (ii) that the three MOOCs were adequate to teach a global and diverse audience in this topic, reaching even participants from resource-low countries. Therefore, MOOCs should be included in the discussion on how to disseminate knowledge and methodological expertise globally, as they are an effective mean to explain and teach about the complex links and dynamics between climate change and health.
Implantable Cardioverter Defibrillator mHealth App for Physician Referrals and eHealth Education: ICD-TEACH Pilot Study (Preprint)
Authors: Gandhi Sumeet , Morillo Carlos A , Schwalm Jon-David
Published: March 2018

BACKGROUND

Mobile health (mHealth) decision tools for implantable cardioverter defibrillator may increase physician knowledge and overall patient care.

OBJECTIVE

The goals of the ICD-TEACH pilot study were to design a smartphone app or mHealth technology with a novel physician decision support algorithm, implement a direct referral mechanism for device implantation from the app, and assess its overall usability and feasibility with physicians involved in the care of patients with an implantable cardioverter defibrillator.

METHODS

The initial design and development of the mHealth or smartphone app included strategic collaboration from an information technology company and key stakeholders including arrhythmia specialists (electrophysiologists), general cardiologists, and key members of the hospital administrative team. A convenience sampling method was used to recruit general internists or cardiologists that refer to our local tertiary care center. Physicians were asked to incorporate the mHealth app in daily clinical practice and avail the decision support algorithm and direct referral feature to the arrhythmia clinic. Feasibility assessment, in the form of a physician survey, was conducted after initial mHealth app use (within 3 months) addressing the physicians’ overall satisfaction with the app, compliance, and reason for noncompliance; usability assessment of the mHealth app was addressed in the physician survey for technical or hardware problems encountered while using the app and suggestions on improvement.

RESULTS

A total of 17 physicians agreed to participate in the pilot study with 100% poststudy survey response rate. Physicians worked in an academic practice, which included both inpatient and ambulatory care. System Usability Scale was applied with an average score of 77 including the 17 participants (>68 points is above average). Regarding the novel physician decision support algorithm for implantable cardioverter defibrillator referral, 11% (1/9) strongly agreed and 78% (7/9) agreed that the algorithm for device eligibility was easy to use. Only 1 patient was referred through the direct referral system via the mHealth app during the pilot study of 3 months. Feasibility assessment showed that 46% (5/11) strongly agreed and 55% (6/11) agreed that the mHealth app would be utilized if integrated into an electronic medical record (EMR) where data are automatically sent to the referring arrhythmia clinic.

CONCLUSIONS

The ICD-TEACH pilot study revealed high usability features of a physician decision support algorithm; however, we received only 1 direct referral through our app despite supportive feedback. A specific reason from our physician survey included the lack of integration into an EMR. Future studies should continue to systematically evaluate smartphone apps in cardiology to assess usability, feasibility, and strategies to integrate into daily workflow.
Improving Health-Related Quality of Life of Patients With an Ostomy Using a Novel Digital Wearable Device: Protocol for a Pilot Study (Preprint)
Authors: Rouholiman Dara , Gamble Jamison G , Dobrota Sylvie D , Encisco Ellen M , Shah Ashish G , Grajales III Francisco J , Chu Larry F
Published: March 2018

BACKGROUND

Ostomy surgeries involving the placement of an ostomy bag (eg, colostomy, ileostomy, urostomy, etc) have been shown to have a negative impact on health-related quality of life. To date, no studies have been conducted examining what impact, if any, wearable biosensors have on the health-related quality of life of ostomy patients.

OBJECTIVE

In the present study, we plan to assess the quality of life of ostomy patients using the Ostom-i alert sensor, a portable, wearable, Bluetooth-linked biosensor that facilitates easier ostomy bag output measurements. We hypothesize that using the Ostom-i alert sensor will result in an improved, ostomy-specific, health-related quality of life as compared to baseline measurement before the use of the sensor.

METHODS

A total of 20 ostomy patients will be screened and recruited to participate in this prospective, observational, cross-over pilot study using an Ostom-i alert sensor for one month. The primary outcome of this study will compare ostomy-specific, health-related quality of life at baseline (prior to Ostom-i alert sensor use) to ostomy-specific, health-related quality of life after 2 and 4 weeks of Ostom-i use by utilizing the City of Hope Quality of Life Questionnaire for Patients with an Ostomy. Secondary outcomes of general health-related quality of life and adjustment to ostomy will be evaluated using the Medical Outcomes Study 36-item short form health survey and the Olbrisch Ostomy Adjustment Scale Short Form 2.

RESULTS

The project was funded by the Department of Anesthesiology, Perioperative and Pain Medicine at Stanford University School of Medicine. Enrollment is currently underway and data analysis is expected to be completed in 2018.

CONCLUSIONS

Proposed benefits of mobile, internet-linked personal health monitors, such as the Ostom-i, include a reduction in the cost of care by reducing resource utilization and infection rates, improving patient-provider communication, reducing time spent as an inpatient as well as improved quality of life. Prior studies have demonstrated decreased health-related quality of life in patients with an ostomy bag. We aim to examine the extent to which the Ostom-i alert sensor affects the health-related quality of life of its users. The Ostom-i alert sensor has the potential to improve quality of life of users by giving them the freedom and confidence to partake in daily activities with the knowledge that they can check how full their ostomy bag is in a private, discrete manner.

How Online Quality Ratings Influence Patients� Choice of Medical Providers: Controlled Experimental Survey Study (Preprint)
Authors: Yaraghi Niam , Wang Weiguang , Gao Guodong (Gordon) , Agarwal Ritu
Published: March 2018

BACKGROUND

In recent years, the information environment for patients to learn about physician quality is being rapidly changed by Web-based ratings from both commercial and government efforts. However, little is known about how various types of Web-based ratings affect individuals’ choice of physicians.

OBJECTIVE

The objective of this research was to measure the relative importance of Web-based quality ratings from governmental and commercial agencies on individuals’ choice of primary care physicians.

METHODS

In a choice-based conjoint experiment conducted on a sample of 1000 Amazon Mechanical Turk users in October 2016, individuals were asked to choose their preferred primary care physician from pairs of physicians with different ratings in clinical and nonclinical aspects of care provided by governmental and commercial agencies.

RESULTS

The relative log odds of choosing a physician increases by 1.31 (95% CI 1.26-1.37; P<.001) and 1.32 (95% CI 1.27-1.39; P<.001) units when the government clinical ratings and commercial nonclinical ratings move from 2 to 4 stars, respectively. The relative log odds of choosing a physician increases by 1.12 (95% CI 1.07-1.18; P<.001) units when the commercial clinical ratings move from 2 to 4 stars. The relative log odds of selecting a physician with 4 stars in nonclinical ratings provided by the government is 1.03 (95% CI 0.98-1.09; P<.001) units higher than a physician with 2 stars in this rating. The log odds of selecting a physician with 4 stars in nonclinical government ratings relative to a physician with 2 stars is 0.23 (95% CI 0.13-0.33; P<.001) units higher for females compared with males. Similar star increase in nonclinical commercial ratings increases the relative log odds of selecting the physician by female respondents by 0.15 (95% CI 0.04-0.26; P=.006) units.

CONCLUSIONS

Individuals perceive nonclinical ratings provided by commercial websites as important as clinical ratings provided by government websites when choosing a primary care physician. There are significant gender differences in how the ratings are used. More research is needed on whether patients are making the best use of different types of ratings, as well as the optimal allocation of resources in improving physician ratings from the government’s perspective.

Situación de la agricultura de mayos y mestizos del norte de Sinaloa, México
Authors: Lara Ponce Estuardo , Valdés Vega J. Luis , Medina Torres S. Martín , Martínez Ruiz Rosa
Published: March 2018

En la localidad de Jahuara II se realizó una investigación mixta, con el objetivo de sistematizar y comparar información ambiental, social, cultural y económica de la agricultura de maíz, que tradicionalmente practican agricultores indígenas mayos y mestizos. La metodología incluyó revisión documental, observación participante, entrevistas y encuestas con un muestreo intencional a 53 ejidatarios entre 49 y 80 años. La interpretación de datos ambientales señala que las limitantes para la producción de maíz son la escasa precipitación y las bajas temperaturas. En lo sociocultural, ambos grupos conservan elementos de su identidad asociadas al conocimiento agrícola. Tecnológicamente practican una agricultura comercial y similar en sus componentes; sin embargo, la semilla criolla de maíz es más empleada por los mayos, quienes comparativamente con los mestizos obtuvieron rendimientos ligeramente mayores en riego, como de temporal. En lo económico existe una relación costo/beneficio promedio favorable en ambos grupos de agricultores, aunque los costos de producción por hectárea sembrada son elevados en ambos casos. Los mayos han perdido terrenos de cultivo por razones socioeconómicas, han dejado de sembrar superficies de maíz criollo y han abandonado prácticas tradicionales. La erosión del conocimiento de la agricultura indígena se observa en la posible extinción de la diversidad de los maíces criollos de la región, situación que impacta el patrimonio biocultural de los mayos y mestizos. Es urgente valorar los conocimientos ancestrales del manejo de la agricultura, cuyo potencial genético es reconocido por los centros de investigación agrícola y significan una expectativa favorable de estudio para enfrontar la problemática climática regional.

Published: March 2018

O artigo tem como objetivo compreender as configurações e perspectivas para a universalização do acesso e às condições de trabalho do professor no Ensino Médio. A discussão foi realizada com base em indicadores arrolados à qualidade social, com destaque para Taxa de Frequência Líquida e Esforço Docente. A análise explicita disparidades regionais em relação às proposições do Plano Nacional de Educação (2014-2024). Aponta um contexto distante do proposto nas metas 3, 17 e 18 do referido Plano e evidencia desafios em relação para a universalização do acesso e as condições de trabalho do professor nas cinco regiões brasileiras. Sugere que o problema da qualidade social do Ensino Médio não se resolverá com a flexibilização curricular proposta na Lei 13.415/2017. Um caminho alvissareiro seria a universalização do acesso, mormente aos jovens de 15 a 17 anos, e a transformação da docência em uma profissão socialmente atraente. O caminho escolhido pelos mentores da reforma talvez seja o menos promissor.
Corporate brand extensions based on the purchase likelihood: Governance implications
Authors: Garefalakis Alexandros , Goumas Spyridon , Charamis Dimitrios , Maroukla Eirini
Published: March 2018

This paper is examining the purchase likelihood of hypothetical service brand extensions from product companies focusing on consumer electronics based on sector categorization and perceptions of fit between the existing product category and image of the company. Prior research has recognized that levels of brand knowledge eases the transference of associations and affect to the new products. Similarity to the existing products of the parent company and perceived image also influence the success of brand extensions. However, sector categorization may interfere with this relationship. The purpose of this study is to examine Greek consumers’ attitudes towards hypothetical brand extensions, and how these are affected by consumers’ existing knowledge about the brand, sector categorization and perceptions of image and category fit of cross-sector extensions. This aim is examined in the context of technological categories, where less-known companies exhibited significance in purchase likelihood, and contradictory with the existing literature, service companies did not perform as positively as expected. Additional insights to the existing literature about sector categorization are provided. The effect of both image and category fit is also examined and predictions regarding the effect of each are made.

Authors: YÖRÜK Emre , SEFER Özlem
Published: March 2018

Fusarium culmorum (W.G. Smith) leads
to economic losses in wheat and
barley fields in Turkey as well as in many countries worldwide as a result of
head blight and crown rot diseases. In this study, in vitro growth capacity of 33 F.
culmorum isolates originating from Turkey and the relationship between phenotypic
and genetic characteristics obtained based on similarities of FcMgv1, FcStuA and FcVeA genes
were investigated. Linear growth rate
values were recorded at 4th and 7th days of incubation.
The mean linear growth rate values ranged from 7.58±1.06
to 14.7±1.26mm/day. The isolates F2 and 18F with relatively high linear
growth values and the isolates 12F and F19 with relatively low linear growth
values, were selected to be used in multiloci based genotyping analysis. FcMgv1, FcStuA and FcVeA genes
were amplified in lengths of 1733, 2001 and 1898bp, respectively. The genes
were sequenced, aligned and then subjected to BLASTn and to maximum likelihood
topology analysis. Nucleotide sequence of each gene showed maximum hit with
associated genes deposited in NCBI with 0.0-0.0 E-values and 1188 to 3256 bit
scores. Alignment analysis resulted in at least 89% bootstrap support.
Moreover, isolates with similar linear growth rates were co-clustered in
phylogenetic analysis. The findings obtained in this study showed that the
three genes which are essential for fungal survival could be used in genetic
characterization analysis and in revealing the associations between their
genetic and phenotypic characteristics.

The Mesoscale Convective Systems with bow echo radar signatures as an example of extremely severe and widespread geohazard in Poland
Authors: Widawski Artur , Pilorz Wojciech
Published: March 2018

In the last two decades we can notice a significant increase of severe anemological events, which are mostly connected with mesoscale convective systems and a cold front of a deep low-pressure system. One of them are very strong winds with speeds more than 25 m/s. They caused material damage and threatening people's lives. The most dangerous are winds generated by mesoscale convective systems where radar reflectivity signatures of bow echo/derecho appeared. In this paper the area of occurrence of such phenomenon in Poland are described and the features of bow echo signatures on radar images are presented and explained. Additionally one of the most severe event and still very weakly known episode of 11th August 2017 derecho in Poland is analysed. The damage data from European Severe Weather Database (ESWD) were analysed to confirm if the August 11th storm met derecho criteria. To identify the radar reflectivity signatures inside MCC the data from the Polish Institute of Meteorology and Water Management shared on the radar-opadow.pl site were used. The CAPPI 1 km data were very useful to determine the convective forms. After that the data from synoptic station were examined for presenting the running of selected meteorological elements. Finally, some information about material damage in infrastructures and forests are mentioned.
Gender and economic orientation as correlates of attitudes towards environmental abuse: A study of a group of Nigerian undergraduates
Authors: Ibrahim Fausat M. , Ibrahim Bashirat A.
Published: March 2018

Equity is central to concerns over environmental sustainability. Gender and economic power constitute prime bases of inequalities in human society. Moreover, university education has the potential to produce ideal individuals equipped to advance noble causes including environmental sanity. Hence, this study was designed to examine how economic and gender orientation affects attitude towards environmental abuse among a group of Nigerian undergraduates. Structured questionnaire were self-administered to 1120 randomly selected respondents and 1098 were analyzed. Multi-item measures were used to assess variables. One way ANOVA, Brown-Forsythe's test and Spearman's correlation r were used to analyze data. Results show that the mean score for attitudes towards environmental abuse was high (5.38±0.87, min. = 1.0, max. = 7.0) but, the generic pattern for attitude was fairly environmentally friendly because only 56.7% of respondents scored the mean or above. Age, sex and marital status had no effect on their attitude (p > 0.05) but religion and field of study did (p < 0.05). Economic and gender orientations were significantly and positively related to attitude towards environmental abuse (p < 0.05). Being Muslim and Christian as opposed to being a practitioner of a traditional religion; and undertaking studies within the field of biology and life sciences as well as science and technology, as opposed to social sciences, humanities and arts, predisposes students to healthier attitudes towards environmental abuse. Collectivist economic orientation and egalitarian gender orientation predisposes students to a healthier attitude towards environmental abuse.
Aplication of IDW and RBF methods to develop models of temperature distribution within a spoil tip located in Wojkowice, Poland
Authors: Zarychta Adrian , Zarychta Roksana
Published: March 2018

This article describes two methods of showing the distribution of temperature on the surface and inside a spoil tip (coal mine waste dump) located in Wojkowice (in the Silesian Voivodeship). Two deterministic estimation methods were tested, i.e., Inverse Distance Weighting (IDW) and Radial Basis Functions (RBF). According to isotherm maps the highest temperature on the surface of the “Wojkowice” spoil tip was in the NE area, while inside the heap the highest temperature noted was in the SW area. Better results were obtained from the application of the RBF method. A three-dimensional model (3D model) was generated by the method, which visualized the temperature distribution within the “Wojkowice” spoil tip. According to the 3D model of the temperature distribution the greatest heat centre inside the heap in Wojkowice was located in the SW part with a temperature of around 300°C. As a result, it can be concluded that the material of the “Wojkowice” spoil tip is burning out in a NW direction. On the basis of the model obtained it is possible to determine the location of potentially dangerous places which are exposed to possible deformations caused by the material burning under the surface. The results of the research presented make it possible to assess the thermal state of the spoil heap located in Wojkowice, Poland.

Published: March 2018

The study examined land accessibility constraints among migrants in rural border settlements of Ogun State, Nigeria. It specifically examined dimensions, extent of importance of the constraints and their joint interactive influence on land accessibility. Data were collected through questionnaires on migrant household heads. A multi-stage sampling technique was used for the selection of 492 respondents for the study. Data collected were analysed using descriptive and inferential statistics (t-test, relative important index (RII) and correlation statistics). The study revealed that the majority of the sampled migrants were within an active and productive population (31-60 years). Also, the larger percentage of the respondents were male (64.8%), married (70%), farmers (67.2%) with no formal education (51.3%). Most of the migrants have stayed above 6 years (79.8%) in the study area. This is an indication that migrants would have detailed experience about their land accessibility constraints. Findings showed that the high cost of land was the major constraint to land accessibility and non-availability of land (scarcity) was the least constraint. The study further revealed that the high cost of land, inability to transfer land, difficulty in land transaction and insecure tenure jointly influenced migrants' access to land in the study area. The study therefore recommended the need for an efficient land administration and governance at local government level in order to accommodate the attendant needs of rural migrants in the study area.
