Spatiotemporal patterns of non-native terrestrial gastropods in the contiguous United States
Authors: Gladstone Nicholas S. , Bordeau Trystan A. , Leppanen Christy , McKinney Michael L.
Published: June 2020

The contiguous United States (CONUS) harbor a significant non-native species diversity. However, spatiotemporal trends of some groups such as terrestrial gastropods (i.e., land snails and slugs) have not been comprehensively considered, and therefore management has been hindered. Here, our aims were to 1.) compile a dataset of all non-native terrestrial gastropod species with CONUS occurrence records, 2.) assess overarching spatiotemporal patterns associated with these records, 3.) describe the continental origin of each species, and 4.) compare climatic associations of each species in their indigenous and introduced CONUS ranges. We compiled a georeferenced dataset of 10,097 records for 22 families, 48 genera, and 69 species, with > 70% of records sourced from the citizen science database iNaturalist. The species Cornu aspersum Müller, 1774 was most prevalent with 3,672 records. The majority (> 92%) of records exhibit an indigenous Western European and Mediterranean distribution, with overlap in broad-scale climatic associations between indigenous and CONUS ranges. Records are most dense in urban metropolitan areas, with the highest proportion of records and species richness in the state of California. We show increased prevalence of non-native species through time, largely associated with urbanized areas with high human population density. Moreover, we show strong evidence for a role for analogous climates in dictating geographic fate and pervasiveness between indigenous and CONUS ranges for non-native species.

Place des discours programmateurs dans le genre textuel regroupant les discours qui régulent et incitent à l’action
Authors: Adam Jean-Michel
Published: June 2020

Le vaste et très hétérogène ensemble discursif, constitué par les textes qui disent ou conseillent de faire va des textes injonctifs et procéduraux aux différentes formes de conseils, peut-il être étendu aux discours programmateurs ? Pour répondre à cette question, l’auteur se demande d’abord de quelle théorie des genres et du texte nous avons besoin pour maîtriser la grande diversité des genres de discours réunis dans ce genre textuel. Il examine ensuite les propriétés linguistiques partagées qui permettent de définir un genre de textes régulant et incitant à l’action, élargi aux discours programmateurs.
La complexité régulatrice des discours programmateurs. Circuits sociaux de la modalisation et instances critiques
Authors: Basso Fossali Pierluigi
Published: June 2020

Les discours programmateurs sont affectés par une double contrainte : présenter l’organisation d’une suite d’actions coordonnées selon une finalité et demander une interprétation avisée des consignes, en les adaptant au contexte d’application. En lutte contre un manque d’organisation ou des programmations inexpertes, les discours programmateurs doivent s’appuyer sur les compétences de l’exécutant, ce qui suggère de préciser à l’avance les limites de leurs ambitions et leur vocation maïeutique : faire exprimer des décisions qualifiées. Derrière leur caractère prosaïque et servile, les discours programmateurs cachent une problématisation de l’agir social selon un circuit de mandats et d’appropriations interprétatives. Cela nous invite à discuter, à travers des exemplifications, l’utilisation trop généralisante du terme incitation pour qualifier la modalisation prototypique du discours programmateur.
Programmation et incitation à l’action dans les textes de conseils économiques
Authors: Emediato Wander
Published: June 2020

Une distinction entre programmation de l’action et incitation à l’action peut s’avérer utile à condition d’en donner des critères. ‹Programmer› et ‹inciter› ne semblent pas être des attitudes de même nature ni engager des formes linguistiques et discursives tout à fait similaires. Pour les textes programmateurs prototypiques, comme les recettes de cuisine et les modes d’emploi, les caractéristiques procédurales sont dominantes mais il y a des textes où la complémentarité entre incitation à l’action et programmation semble constituer une nécessité interne. C’est ce que l’on essayera de démontrer en analysant un texte de conseils économiques du FMI.
Discours programmateurs : le cas des recettes de cuisine en français classique et en français moderne
Authors: Rossi-Gensane Nathalie , Goux Mathieu
Published: June 2020

Il est observé dans cet article comment la fabrique des recettes écrites de cuisine a évolué du français classique au français moderne. Si, notamment, la présence ou l’absence de constructions détachées participiales à rôle d’organisateur temporel permet d’opposer respectivement recettes classiques et recettes modernes, il est montré que c’est avant tout pour le xx e  siècle, et donc pour une partie seulement des recettes de l’époque moderne, que l’on peut proprement parler de ‹discours programmateurs›. En effet, les recettes d’avant 1900 ne relèvent encore que d’un genre en constitution dans la mesure où, en particulier, leur font défaut l’effacement systématique de la source énonciative et, en lien avec une construction à longue portée des chaînes de référence et une structuration périodique, une forte segmentation typographique.
La polarisation entre valeur-travail et valeur-utilité en économie : une perspective généalogique
Authors: Gazier Bernard
Published: June 2020

Cet article exploratoire vise à replacer les débats critiques actuels sur la théorie de la valeur en économie dans leur socle épistémologique afin de caractériser l’espace de leur déploiement. Il utilise les apports des travaux de Foucault, en les explicitant et en les prolongeant. Il présente des pistes expliquant pourquoi les discussions actuelles manifestent l’affaiblissement de la polarisation entre valeur-travail et valeur-utilité, et ouvrent sur une socio-économie des processus de valorisation.
Effects of non-accident and non-punishment experiences: a planned behaviour perspective
Authors: Auzoult Laurent , Lheureux Florent
Published: June 2020

Nous présentons une étude qui examine l’impact des expériences de non-accident (ENA) sur les violations de règles de sécurité au travail. Nous introduisons également un nouveau concept, l’expérience de non-sanction (ENS). Ces expériences rendent compte du fait que des transgressions de règles de sécurité ne sont pas suivies d’accident ou de sanction tel que le script de sécurité le prévoit dans les organisations. Nous analysons l’impact de ces deux types d’expérience pour soi et pour autrui sur les construits de la théorie du comportement planifié (Theory of Planned Behaviour, TPB), à savoir l’attitude, la norme subjective, le contrôle comportemental et l’intention comportementale. Nous introduisons également l’habitude pour rendre compte de la composante automatique du comportement. 180 participants ont répondu à un questionnaire mesurant les expériences, les construits TPB et les habitudes associées aux violations de règles de sécurité au travail. Les résultats mettent en évidence que les expériences personnelles déterminent l’attitude alors que les expériences d’autrui déterminent la norme subjective. Les expériences personnelles ont également un impact sur l’habitude et l’intention. La discussion porte sur l’intégration de ces notions au niveau du climat de sécurité et sur la nécessité de développer une culture de sécurité où tout le monde apprend où se situent les limites des pratiques acceptables.
Superclose analysis of a two-grid finite element scheme for semilinear parabolic integro-differential equations
Authors: Xu Changling , Hou Tianliang
Published: June 2020

In this paper, a two-grid finite element scheme for semilinear parabolic integro-differential equations is proposed. In the two-grid scheme, continuous linear element is used for spatial discretization, while Crank-Nicolson scheme and Leap-Frog scheme are ultilized for temporal discretization. Based on the combination of the interpolation and Ritz projection technique, some superclose estimates between the interpolation and the numerical solution in the $ H^1 $-norm are derived. Notice that we only need to solve nonlinear problem once in the two-grid scheme, namely, the first time step on the coarse-grid space. A numerical example is presented to verify the effectiveness of the proposed two-grid scheme.
Uniform high-order convergence of multiscale finite element computation on a graded recursion for singular perturbation
Authors: Jiang Shan , Liang Li , Sun Meiling , Su Fang
Published: June 2020

A multiscale finite element method is proposed for addressing a singularly perturbed convection-diffusion model. In reference to the a priori estimate of the boundary layer location, we provide a graded recursion for the mesh adaption. On this mesh, the multiscale basis functions are able to capture the microscopic boundary layers effectively. Then with a global reduction, the multiscale functional space may efficiently reflect the macroscopic essence. The error estimate for the adaptive multiscale strategy is presented, and a high-order convergence is proved. Numerical results validate the robustness of this novel multiscale simulation for singular perturbation with small parameters, as a consequence, high accuracy and uniform superconvergence are obtained through computational reductions.
On the mod p Steenrod algebra and the Leibniz-Hopf algebra
Authors: Turgay Neşet Deniz
Published: June 2020

Let $ p $ be a fixed odd prime. The Bockstein free part of the mod $ p $ Steenrod algebra, $ \mathcal{A}_p $, can be defined as the quotient of the mod $ p $ reduction of the Leibniz Hopf algebra, $ \mathcal{F}_p $. We study the Hopf algebra epimorphism $ \pi\colon \mathcal{F}_p\to \mathcal{A}_p $ to investigate the canonical Hopf algebra conjugation in $ \mathcal{A}_p $ together with the conjugation operation in $ \mathcal{F}_p $. We also give a result about conjugation invariants in the mod 2 dual Leibniz Hopf algebra using its multiplicative algebra structure.
A multi-mode expansion method for boundary optimal control problems constrained by random Poisson equations
Authors: Li Jingshi , Zhang Jiachuan , Ju Guoliang , You Juntao
Published: June 2020

This paper develops efficient numerical algorithms for the optimal control problem constrained by Poisson equations with uncertain diffusion coefficients. We consider both unconstrained condition and box-constrained condition for the control. The algorithms are based upon a multi-mode expansion (MME) for the random state, the finite element approximation for the physical space and the alternating direction method of multipliers (ADMM) or two-block ADMM for the discrete optimization systems. The compelling aspect of our method is that, target random constrained control problem can be approximated to one deterministic constrained control problem under a state variable substitution equality. Thus, the computing resource, especially the memory consumption, can be reduced sharply. The convergence rates of the proposed algorithms are discussed in the paper. We also present some numerical examples to show the performance of our algorithms.

Authors: Herman C. , Pompeu D. R. , Campos D. , Larondelle Y. , Rogez H. , Baeten V.
Published: June 2020

This work focuses on the characterization of the oxidation of the oil from sacha inchi seeds (Plukenetia volubilis) under accelerated conditions at 60 ºC for 15 days. Five samples were monitored: three supplemented with 200 ppm of non-hydrolyzed or partially hydrolyzed (for 4 and 9 hours) extracts from tara (Caesalpinia spinosa) pods, one without antioxidant and one with 200 ppm of BHT. Several conventional tech­niques (induction time, peroxide value, conjugated dienoic acid, p-anisidine value, total unsaturated fatty acids and α-linolenic acid contents) and the MIR spectroscopy coupled with chemometric tools were used and com­pared. The results revealed that whatever the antioxidant added, the oil from sacha inchi is fairly stable over time. The results also pointed out that extracts from tara pods, mainly those partially hydrolyzed, were more efficient than BHT against oil oxidation for up to 7 days. Finally, this paper shows that MIR spectroscopy pres­ents an interesting alternative technique for the monitoring of the oxidation of the oil from sacha inchi.
Geminate blockage in Logoori harmony with no added machinery
Authors: Odden David
Published: June 2020

Following the demise of the SPE theory of phonology, little attention was paid to how rules should be formulated. Instead, there was a general trend to minimize the language-specific component of a grammar, to factor out recurring patterns and state them as independent constraints or parameters. The richer representations of autose­gmental phonology additionally led to uncertainty in rule formulation, primarily because of questions about what the correct representations are, but also because specifying dominance and precedence relations is more complex than just specifying precedence relations.

This paper discusses a vowel harmony rule in the Bantu language Logoori, which is blocked by an intervening gemi­nate consonant. It is typologically surprising that an intervening geminate has an effect on harmony, and there is no clear model for how such an effect in a rule should be encoded. It is shown that the effect follows naturally from correctly formalizing the rule, with attention to how rule and representational substrings are matched, and no rule-external conditions on the rule are necessary.

Approaches to Address the Operational Limitations of MANETs through Ad Hoc Mobile Cloud Computing Paradigm
Authors: Kurni Muralidhar , K Madhavi
Published: June 2020

Mobile Ad hoc Networks (MANETs) are getting essential to wireless communications because of the growing popularity of mobile devices. However, mobile devices face several challenges in their resources (eg., battery life, storage, and bandwidth) and communication (e.g., mobility and, security). Limited resources considerably impede the improvement of service qualities. MCC permits resources in cloud computing platforms to be used to overcome the dearth of native resources in mobile devices. However, this hinders a mobile user from taking part in a cloud computing service if a connection to the cloud computing platform is both unobtainable or too dear to afford. Therefore, an initial solution will be to use resources from nearby devices instantly. Such a paradigm is known as mobile ad hoc cloud computing where each mobile device can use the services and resources of its neighbor devices. This paper shortly explains the contributions done by us to overcome the three vital operational limitations of mobile devices namely connectivity, storage and, processing capability through the Mobile Ad Hoc Cloud Computing Paradigm. The potential promise of the proposed approaches is evaluated through simulations. Our proposals, taken together intend to increase the operational efficiency of MANETs.
How to Build Effective Interprofessional Healthcare Teams
Authors: Ellison Stefanie R. , Bartlett Christi L. , Ruehter Valerie L.
Published: June 2020

Building effective interprofessional (IP) teams is an important process for healthcare systems across the world. In order to be truly effective, professional degree programs must teach our future health professionals to learn and collaborate on teams during their education. The goal of building effective IP healthcare teams will be achieved when each healthcare system effectively supports IP collaboration, the development of dynamic teams, and the appropriate use of resources. Advancing the effort to build effective IP healthcare teams will take an investment from key stakeholders such as educators, faculty and students, leaders and researchers in academic medicine, hospital and system administrators, policymakers, as well as patients and their families to create a culture of IP collaboration and provide the resources necessary to be sustainable and successful. This chapter will serve to show that effective IP healthcare teams can successfully improve patient outcomes, provide quality care, improve the healthcare team's experience, and reduce costs.
Building Interprofessional Competencies Into Medical Education and Assessment
Authors: Mackintosh Susan Elaine , Katsaros Emmanuel
Published: June 2020

The goal of allopathic and osteopathic medical education is to develop the medical student into a competent and caring physician. As the evolving healthcare system continues to evolve and intersect with an increased breadth and depth of medical knowledge and an aging and more complex patient population, the emerging physician must now rely more on a team-based approach to patient-centered healthcare. Integrating interprofessional competencies into the span of the medical education and assessment process via the core competencies and the Entrustable Professional Activities has the potential to help instill not only the knowledge and skills required to practice as a member of an interprofessional healthcare team, but can also help to normalize the culture and thus the expectation of practicing collaboratively with all members of the health team toward the goal of improved patient outcome.
How to Use Technology and Telehealth to Enhance the Interprofessional Community of Practice
Authors: Waldman Steven D. , Waldman Corey W. , Waldman Reid A. , Abuabara Judith Ovalle
Published: June 2020

The widespread availability and use of digital technology including the internet, cell phones, remote electrocardiogram, PACS (picture archiving and communication) systems, and video chat platforms such as Facetime and Zoom have fueled the growth of telehealth. In 2013, only about 350,000 Americans utilized telehealth technology as part of their care plan, and most of these patient interactions involved the use of telephone consults. By the end of 2018, that number had jumped to over 7,000,000. Coupled with the exponential increase in the use of telehealth technology has been a rapid decrease in the cost of telehealth technology and HIPAA compliant telehealth platforms. The ease of use and relative affordability of these technologic advances make telehealth technology an ideal tool to enhance the interprofessional community of practice.

Published: June 2020

The local authorities' incubator for social enterprises should be supporting the connection of local companies that apply CSR with social enterprises that are trying to succeed social value. The research in this chapter relied on a systematic literature review. After reviewing the literature, a methodology has been developed that describes the process of designing and implementing a local authorities' incubator and the synergies with social enterprises and CSR. The benefit of a local authorities' incubator in the field of social entrepreneurship is the facilitation of new social enterprises to overcome knowledge barriers and implement best business practices. Finally, in this chapter, it is suggested that the cooperation between local companies that apply CSR and local social enterprises under the guidance and support of local authorities' incubator could create synergies and produce new local certified PGI (protected geographical indication) or PDO (protected designations of origin) social/ethical/green/fair-trade products and services and promote the local economy.

A Novel Approach for Wind Speed Forecasting Using LSTM-ARIMA Deep Learning Models
Authors: Bali Vikram , Kumar Ajay , Gangwar Satyam
Published: June 2020

The term which is used to predict wind speed to produce wind power is wind speed forecasting. Deep learning, is a form of AI, basically indulging in artificial intelligence and thus can greatly increase the precision rate on larger datasets. In this research paper, the two techniques are being used together to obtain the better forecasting results. Both the techniques are forecasting based and combining LSTM and deep learning can increase the forecast rate because of the pattern remembering attribute of LSTM over a longer interval/period of time. If there is the inclusion of the ARIMA model the likelihood of a future value lying between two indicated limits is increased. So, overall if both the techniques are hybridized than it is most probable that the obtained results should be more accurate than both the techniques used separately. So, the main focus of this research article is on the efficiency and evaluation of hybridized LSTM-ARIMA model to predict wind speed forecasting.

A New Intelligent Biologically-Inspired Model for Fault Tolerance in Distributed Embedded Systems
Authors: Mehalaine Ridha , Boutekkouk Fateh
Published: June 2020

The objective of this work is to present a new heuristic for solving the problem of fault tolerance in real time distributed embedded systems. The proposed idea is to model the distributed embedded architecture inspiring from the rennin-angiotensin aldosterone (RAAS) biological system which plays a major role in the pathophysiology of the cardiovascular system, from the point of view of pressure regulation and vascular, cardiac and nephrological remodeling. The proposed heuristic deals with uncertain information on a set of periodic tasks that run on multiple processors and satisfies certain temporal and energetic constraints from which the scheduling and the distribution of these tasks on the different processors are performed. In order to respect the energy constraints, this article proposes the introduction of energy consumption at the dynamic task scheduling level by using the dynamic voltage scaling (DVS) technique. The authors have seen that the introduction of a detection/prevention mechanism against potential errors in the proposed algorithm is a must for good results.

Metaheuristics Guided by the Apriori Principle for Association Rule Mining
Authors: Derouiche Abir , Layeb Abdesslem , Habbas Zineb
Published: June 2020

Association rule mining (ARM), one of the most known tasks in data mining, is considered as an optimization problem. The ARM problem can be solved either by exact methods or by metaheuristics. Exact methods such as Apriori algorithm are very efficient to deal with small and medium datasets. However, when dealing with large size datasets, these methods suffer from time complexity. Metaheuristics are proven faster but most of them suffer from accuracy. To deal with these two challenging issues, this work investigates to enhance metaheuristics and proposes hybrid approaches, which combine metaheuristics and the Apriori principle to intelligently explore the association rules space. To validate the proposed approaches the chemical reaction optimization metaheuristic (CRO) was used. Intensive experiments have been carried out and the first results are very promising in terms of accuracy and processing time.

Authors: Touggui Youssef , Belhadi Salim , Mechraoui Salah Eddine , Yallese Mohamed Athmane , Temmar Mustapha
Published: June 2020

Stainless steels have gained much attention to be an alternative solution for many manufacturing industries due to their high mechanical properties and corrosion resistance. However, owing to their high ductility, their low thermal conductivity and high tendency to work hardening, these materials are classed as materials difficult to machine. Therefore, the main aim of the study was to examine the effect of cutting parameters such as cutting speed, feed rate and depth of cut on the response parameters including surface roughness (Ra), tangential cutting force (Fz) and cutting power (Pc) during dry turning of AISI 316L using TiCN-TiN PVD cermet tool. As a methodology, the Taguchi L27 orthogonal array parameter design and response surface methodology (RSM)) have been used. Statistical analysis revealed feed rate affected for surface roughness (79.61%) and depth of cut impacted for tangential cutting force and cutting power (62.12% and 35.68%), respectively. According to optimization analysis based on desirability function (DF), cutting speed of 212.837 m/min, 0.08 mm/rev feed rate and 0.1 mm depth of cut were determined to acquire high machined part quality

Authors: Naihi Hafizah Binti
Published: June 2020

The extensive use of heavy metals such as copper in various industries has discharged a large amount of the metals into the environment which is toxic at higher concentrations. The use of low-cost agricultural waste of biological origin such as tea waste may be an economic solution to this problem. Tea waste is among the potential material to be developed as an adsorbent for heavy metal ions. Tea waste contains cellulose and lignin which have been reported having an excellent metal binding capacity. This study aims to use tea waste for the removal of Cu2+ ions. The effect of variation in different parameters like initial concentration of Cu2+ ions in solution, adsorbent dosage and contact time were investigated using batch adsorption method. The adsorbent, tea waste was characterized using a compound microscope and FTIR spectroscopy. Experimental results showed that the maximum removal of the copper ion by tea waste at optimum condition (pH 7, 60 min. contact time, 0.8 g adsorbent dose and 0.7 M concentration) is 74%. The adsorbent prepared from tea waste is efficient and it can be conveniently employed as a low-cost alternative in the treatment of wastewater for heavy metal removal.
Tripropyl Chitosan Iodide-Based Gel Polymer Electrolyte as Quasi Solid-State Dye Sensitized Solar Cells
Authors: Yahya Wan Zaireen Nisa , Hong Pang Zhen , Mohd Zain Wan Zul Zahran Wan , Mohamed Norani Muti
Published: June 2020

Electrolyte as one of the major components in dye sensitized solar cells (DSSCs) plays an important role in dye regeneration and as the inner charge carrier transport between electrodes. Gel polymer electrolyte is a potential alternative to liquid electrolytes which suffer of leakage and solvent evaporation. In this present research, functionalization of chitosan by the quaternization reaction of chitosan with iodopropane forming tripropyl chitosan iodide is proposed for the preparation of gel polymer electrolyte. Tripropyl chitosan iodide was characterized by nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). Four different polymer electrolytes were tested at different compositions in presence of iodide/triiodide redox salt and imidazolium ionic liquid in DSSCs configurations. The results show that the gel polymer electrolyte containing the tripropyl chitosan iodide in presence of 1-propyl-3-methylimidazolium iodide ionic liquid showed better performance with power conversion efficiency of 0.415% as compared to the gel polymer electrolyte film without ionic liquid with power conversion efficiency of 0.075%. The results shown the synergistic effects of the polycationic tripropyl chitosan iodide with the ionic liquid 1-propyl-3-methylimidazolium iodide on the photovoltaic performance.

Clay fired bricks are commonly encountered in the construction sector as infill between structural frames. This system has been favoured by builders due to familiarity, ease of manufacture, and they also do not require skilled labourers to erect. Produced from moulded clay and hardened by firing in a kiln, brick production is both energy intensive and high in CO2 emission. Fired bricks are typically held together by cement mortar at the bed and perpend joints which provide very minimal resistance against shearing or flexure. This meant brick walls often require additional wind posts or stiffeners to provide stability. Compressed earth masonry offers an alternative to the conventional brick walling system in that, besides having the advantages of conventional bricks, they also confer higher compressive strengths due to the high-pressure compaction manufacturing process. The high strength allows the system to be adapted into load-bearing masonry system for use in low-rise buildings as an alternative to the more expensive reinforced concrete or steel framing system. The high-pressure compaction process along with high quality moulds also give fair-faced finished to the bricks, allowing them to be used as facing bricks and eliminating the need for surface finishing such as plastering. Additionally, compressed bricks featuring interlocking key holes along the bed joints allows for simplified and faster wall erection process. This review paper aims to document the research progress thus far in adopting the compressed interlocking bricks as a sustainable alternative to current building materials.

A city can comprise of settlements with different ethnic backgrounds in a given geographical space. Ethnic groups can be separately located spatially but that does not imply that their quality of life is similar and facilities are equally distributed. This study thus conducted to identify the patterns of segregation of population according to their ethnicity and the factors behind the ethnically segregated neighbourhood in Thimbirigasyaya Divisional Secretariat Division (DSD), with the help of population data in 2017. This paper employed the Duncan and Duncan’s (1955) method of Dissimilarity Index to calculate the Segregation Index of population by using Microsoft excel software. The levels of segregation are categorized in this study according toMassey & Denton’s (1988) method for Dissimilarity Index.The Geographical Information System (Arc map10.1) was employed to map out the Index of Segregation of twenty Grama Niladhari Divisions (GNDs) in Thimbirigasyaya DSD. Factors behind the segregation were identified by the questionnaire survey in selected GNDs. Results revealed that the patterns of segregation can vary in urban spaces. North-central and North-Eastern part of Thimbirigasyaya DSD received high Segregation Index value for Sinhalese with high socio economical levels. Tamils are moderately segregated in the South-western corner of the DSD. Muslims’ segregation is relatively low in the DSD, but according to Grama Niladhari Divisions (GND) wise, Kuppiyawatta east and Dematagoda GNDs show the highest Muslim population. When different ethnically segregated neighbourhoods in DSD are compared, it is clear that there are several social and economic inequalities, which affect the minor groups comparably. Muslim neighbourhoods are located in underserved areas with fewer facilities and unclean environment with lower economic levels. Therefore, better solution to minimise these problems is to develop mixed ethnic neighbourhood in urban spaces in Sri Lanka.

Sri Lanka is a continental island consisting of 65,610 km2 of land. The country is highly likely to affect by both natural and man-made hazards. Landslides can be identified as one of the major natural hazards. As a developing country, it is very important to identify landslide vulnerability and risks because that can influence future development activities and disaster mitigation programmes. Kiriketioya and Belihuloya watershed areas are located in the second and third pen plain of the country. It belongs to the Imbulpe Divisional Secretariat Division and approximately covers 72km2 of land. The main objective of the study is to identify the landslide vulnerabilities and risks in the study area. The study was based on the data collected from both primary and secondary sources. Secondary data and information were collected through many sources as an extension to the literature review. Primary data were collected through field observations. Arc GIS 10.3 software was used for digitizing, modelling, data analysis and interpretation. Landsat 8 OLI/TIRS (30m resolution) satellite images were used to calculate Normalized Different Vegetation Index (NDVI) and to analyze the land-usage. Weighted overlay methods in Arc GIS was used mainly to create landslide vulnerability map and the risk map. Landslide vulnerable and risk areas were identified and classified into high, medium and moderate zones. Areas of high risk of landslides are located in the high elevation areas. Approximately 60% of the lands of the study area have a moderate to high risk for landslides. Hence, it is essential to implement mitigatory measures to reduce landslide risks for the high and moderate landslides vulnerability lands.

Coastal resources are crucial and important to support life in the planet. Benefits derived from coastal resources are well known and widely recognized. Pigeon Island National Park is one of the best remaining coral reefs with high live coral cover in Sri Lanka and is an ideal location for scuba diving and snorkelling. The objective of this research was to explore the recreational value of the Pigeon Island. A sample of hundred participants including both foreigners and locals were selected using systematic sampling and every fifth person who passes the entry point was interviewed. Contingent valuation method was used in the analysis in the study. The result revealed that majority (92%) of foreigners who visited the island were non- Asians. Almost all the foreign visitors participated in Scenic visit, diving visit, whale watching and Sunbath. Both locals and foreigners ranked diving as the most preferred activity. Average cost for boating was Rs. 1,300 per hour for foreign visitors, average cost for diving was Rs. 3470 per person per hour which were nearly twice the value that of local visitors. Foreign visitors’ mean willingness to pay for diving was Rs.3670 and, for whale watching was Rs.1510. But for local visitor’s willingness to pay for diving visit was Rs.1240, for whale watching was Rs.919.00. Average willingness to pay of the foreign visitors for entrance fee was Rs.1560 and the average willingness to pay of the local visitors for the entrance fee was Rs 644.00. Results of the T test presented that significant difference between foreign visitors and local visitors for total and entrance fee willingness to pay, hours of spending, costs for boating, for diving and for whale watching. Chi square analysis showed that there was a high significant association between the total willingness to pay by the local visitors and the education level of the respondent (X2=76.75, p < 0.01). A significant association was observed between the total willingness to pay by the local visitors and the cost for boating in the Pigeon Island (X2=36.52, p < 0.01). In addition, total willingness to pay was significantly affected by age, hours of spending, number of the group members and expenses for meals. The study revealed that the current entrance fees do not capture the economic value of the Pigeon Island.

Published: June 2020

Nivolumab-induced immune thrombocytopenia (ITP) is a rare process with few reported cases. We present a 67-year-old man with advanced non-small cell lung cancer who was hospitalized with severe thrombocytopenia. Physical exam was notable for petechiae across his chest and extremities as well as bullae in his oral cavity. The patient initially received high-dose glucocorticoids and intravenous immuno - globulin, but did not respond to treatment. He was then started on weekly rituximab and after three doses, there was complete resolution of his thrombocytopenia. Altogether, his presentation was an extreme case and rare side effect of immune checkpoint therapy, known as nivolumab-induced ITP. Diagnosis of nivolumab-induced ITP is challenging given the lack of specific testing and a wide differential diagnosis. There are few cases reporting severe ITP following nivolumab treatment. We highlight the importance of recognizing and treating this rare complication of immunotherapy.
