Case-based Mobile Tourism Attractions Recommender System

The variations and the increasing number of tourism attractions give tourists more choices to enrich their travel experience. However, it also presents drawbacks, including confusing tourists when planning a trip, because they have to choose from many tourist attractions options that match their preferences. In this study, we propose an algorithm that can generate recommendations of tourist attractions to the user using a case-based reasoning approach. Case-based recommendation is chosen because it gives the user a more personalized recommendation that they can customize later on within the application. Besides, the implementation of this approach in the tourism domain is still hard to find. As many as 217 tourist attraction objects in Yogyakarta city are gathered as the case study. We label each object with three attributes, namely category, visitor type, and activities. A similarity function called the simple matching coefficient is used to calculate the item’s score based on the user specification. For assessing the proposed algorithm, we implement the model as an Android application. To evaluate the recommendation result, we use mean absolute error calculation (MAE) and mean absolute percentage error (MAPE), resulting in 4.1 MAE and 5% MAPE, which is considered highly accurate. Thus, the recommendation from the system is well suited to the user’s preference.
Short‐lived fishes: Annual and multivoltine strategies

Lifespan has a formative role on most other lifehistory traits as it defines the timeframe for completion of all lifedetermining processes (Stearns, 1992). Longevity in wild populations is the most relevant lifespan estimate from an evolutionary perspective, because it integrates all longevityshaping forces of natural selection (Monaghan et al., 2008; Nussey et al., 2008). In particular, lifespan in natural populations is moulded by the mode and rate of extrinsic mortality (Maklakov et al., 2015; Medawar, 1952; Williams, 1957), dominated by predation, diseases, competition, natural disasters and accidental deaths (Reichard, 2017). Species with high extrinsic mortality are expected to evolve short lifespans (Medawar, 1952; Williams, 1957) and those species may provide critical insights into how natural selection limits lifespan.

Marking a Quiet Community: Analyzing Narratives of Community Reentry Among Filipino Plea Bargainers

Abstract Since President Rodrigo Duterte launched his war on drugs campaign in 2016, there has been a growing scholarship documenting the empirical analyses of the policy’s drug-related harms. Eighteen Filipino plea bargainers were interviewed and asked to narrate their experiences of eventually returning back to the community after release. Their stories were analyzed using Stephens and Breheny’s (2013) integrated approach to narrative analysis. Three broader categories were evident that evoke the interplay between wider systemic conditions and one’s exercise of restricted agency. Under first broader category of reentering a spatially marked and quiet community, four personal narratives are evident, namely: I don’t want to go out anymore, I just keep away from that place, I don’t see them anymore, and I’m living in a dead town. Under the second broader category of my family upon reentering the community, two personal narratives are evident: I felt ashamed and Where are you going? Don’t use anymore. Under the third broader category of reentering the community without work, three personal narratives are evident: I could not give anything to my children, I did all the work at home, and I’m looking for work, but. Our findings contribute to the examination of interlocking systemic conditions surrounding the accounts of those incarcerated in local police crackdowns. In this context, there is a strong need to respond to the challenges of rebuilding community processes (e.g., permanently delisted from the community drug watchlist) and strengthening employment opportunities in partnership with the local government.
What Can Drive Consumers’ Dining-Out Behavior in China and Korea during the COVID-19 Pandemic?

Currently, living with COVID-19 under certain protective measures still continues as the “new normal” for most of the world. The disruption that the pandemic has caused to societies and economies, especially to the restaurant industry, may last longer than some had thought. This study intended to find out the key drivers of consumers’ dining-out intentions and their internal relationships. We adopted the structural equation modeling (SEM) method with 508 surveys collected from China and Korea. The results were as follows: perceived psychological risks, subjective norms, and enjoyment are influential to consumers’ dining-out intentions but not restaurant precautionary measures or perceived physical risk; subjective norms have direct implications on both perceived psychological and physical risks, while restaurant precautionary measures can only significantly affect perceived physical risk; enjoyment can be negatively influenced by perceived psychological and physical risks; country can moderate the relationships between subjective norms, perceived physical/psychological risk, and enjoyment. This study provides further understanding of the current food consumption patterns, which will help restaurants set up strategies accordingly to sustain their businesses and get them more prepared for any future outbreaks.
Wideband air‐filled ridge substrate‐integrated waveguide

A wideband air‐filled ridge substrate integrated waveguide (AFRSIW) and its transition to microstrip are proposed first in this paper. The AFRSIW combines the broadband advantage of the ridge substrate integrated waveguide (RSIW) and the low loss of the air‐filled SIW (AFSIW). Therefore, the AFRSIW allows for lower cut‐off frequency and broader mono‐modal bandwidth compared with AFSIW with same width and height, because of the involvement of the ridge made of an additional layer of dielectric substrate. Moreover, the AFRSIW has lower loss compared with RSIW due to the removal of the dielectric. The transition from AFRSIW to microstrip consists of a tapered microstrip line and two suppressing stubs. The tapered microstrip line is used to ensure impedance matching, and two suppressing stubs preventing the undesired radiation are introduced to improve the impedance match broadening the operating bandwidth of the transition. The AFRSIW together with the transition is simulated and optimized with HFSS. For demonstration, a back‐to‐back transition prototype is fabricated and measured. A mono‐modal bandwidth of 77.6% with 15 dB return loss is obtained from 8.6 to 19.5 GHz.
Investigating the Effects of Nano Ceramics based Pack Cementation Coatings on Properties of some Biomedical Ti Alloys

Titanium has a unique ability to bind with bone and living tissue, making it an ideal material for orthopedic implants such as knee and hip replacements. The objective is focused on studying the influence of Nano ceramic powder (70%ZrO2 with Y2O3) on different base titanium alloys produced by powder technology technique (Ti-pure, Ti-45%Ni, Ti-10%Co, and Ti-30%Ta) with pretreated surface of implant samples . From XRD patterns, there was no indication that other phases contain any of the diffraction patterns present in samples after (Zro2and Y2o3) deposition. The microstructure observation of all samples showed that both Nano zirconia and yttria were distributed in samples surface and covered, which produced a high modification in morphology of surface. There was considerable increase in hardness value after pack cementation process. It is evident that the porosity percent of the samples after Nano ceramic deposition largely decreased. The results showed that using chemical pre surface treatments and powder technology method was useful to gain adhere and homogenous deposition layer.
A novel method for the evaluation of driving simulator performances

The use of driving-simulator is increasing wide-spreading in the whole automotive sector. The adoption of driving simulator indeed allows evaluating the design choices directly during the design stage thought the man-machine interaction, where “man” means the driver while “machine” means the mathematical model of the car traduced to the driver thought a different machine: the driving simulator. In this research activity a questionnaire was developed to evaluate the performances of a driving simulator focusing on two main aspects. The first one regards the ability of the driving simulator to accurately reproduce the driving feelings without inducing motion sickness sensations. The second instead regards the ability of the driver to objectively judge the vehicle performances throughout a set of parameters. All these aspects were firstly numerically investigated implementing different models showing different dynamics characteristics and successively verified by experimental test at the driving simulator. The drivers scores, about both the accuracy of the mathematical model and the driving simulator, were analysed in order to understand if their feelings match the real behaviour imposed to the car.
A Two-layer Multistage Expansion Planning Method for Adaptability Enhancement of Distribution Networks

With the increasing penetration of distributed generations (DGs) and flexible loads in the distribution network (DN), the existing DN planning methods need an improvement. This paper proposes a two-layer multistage expansion planning method for DN adaptability enhancement, where the optimal construction/upgrade strategy of substations and lines along with the optimal PV configuration strategy are considered. A two-layer adaptive planning model is established and solved by the non-dominated sorting genetic algorithm II (NSGA II). The obtained Pareto-optimal front represents a set of optimal planning schemes meeting the demand of DN economy and adaptability, which is of great significance in theory and practice.
Supported C60-IL-PdNPs as extremely active nanocatalysts for C–C cross-coupling reactions

A C60-ionic liquid hybrid has been covalently linked to three different solid supports, namely amorphous silica, SBA-15 and Fe2O3@SiO2, and the resulting materials have been employed as covalently supported ionic liquid phases (cSILP) in order to immobilize and stabilize palladium nanoparticles (PdNPs). These novel hybrid materials are based on a sort of “matryoshka” system (PdNPs@imidazolium-salt@C60@support) in which the imidazolium-based moieties have not been directly linked to the surface of the support, but they are present in an octopus-like spatial arrangement on the uniformly surface-distributed fullerenes. These materials have been fully characterized and successfully employed as catalysts in C–C bond forming reactions showing, in the case of Suzuki cross-coupling, an outstanding catalytic activity both under classical heating and by irradiating with microwaves. Turn-over frequencies (TOFs) of up to 3 640 000 h−1 have been achieved and the silica-based catalyst showed full recyclability even after 10 cycles.
Effect of Varying Wind Intensity, Forward Speed, and Surface Pressure on Storm Surges of Hurricane Rita

Hurricane storm surges are influenced by several factors, including wind intensity, surface pressure, forward speed, size, angle of approach, ocean bottom depth and slope, shape and geographical features of the coastline. The relative influence of each factor may be amplified or abated by other factors that are acting at the time of the hurricane’s approach to the land. To understand the individual and combined influence of wind intensity, surface pressure and forward speed, a numerical experiment is conducted using Advanced CIRCulation + Simulating Waves Nearshore (ADCIRC + SWAN) by performing hindcasts of Hurricane Rita storm surges. The wind field generated by Ocean Weather Inc. (OWI) is used as the base meteorological forcing in ADCIRC + SWAN. All parameters are varied by certain percentages from those in the OWI wind field. Simulation results are analyzed for maximum wind intensity, wind vector pattern, minimum surface pressure, forward speed, maximum water elevation, station water elevation time series, and high water marks. The results for different cases are compared against each other, as well as with observed data. Changes in the wind intensity have the greatest impact, followed by the forward speed and surface pressure. The combined effects of the wind intensity and forward speed are noticeably different than their individual effects.
Scavenging by fishers in relation to season and other scavengers

Carrion is an energy-rich resource that benefits many organisms, but scavenging involves both profits and risks. Fishers ( Pekania pennanti ) are forest-specialists that scavenge large carcasses but quantitative assessments of their scavenging are lacking. We quantified three characteristics of scavenging behavior by fishers: (a) whether fishers visited a carcass; (b) the time to first visitation of a carcass by fishers; and (c) how long fishers fed at a carcass. We then evaluated the importance of habitat characteristics, cues from other scavenger species, and season on the scavenging behaviors of fishers. Fishers scavenged 25 of the 89 deer carcasses we monitored, and visited carcasses more frequently in winter ( n = 22, 34%) than in summer ( n = 3, 12%). Time to the first fisher visit to a carcass averaged 4.7 (±1.1 SE ) days. On average fishers made 26 (±9 SE ) repeat visits to each carcass they found and fed for 118.1 min (±42.3 SE ) over an average of 6 days; season also influenced their feeding times (120.3 ± 46.0 SE min in winter versus 63.7 ± 44.7 SE min in summer). Fishers had a crepuscular activity pattern while scavenging, but initial visits peaked mid-day in addition to a peak near sunset. Our results suggested that fishers may use cues from other scavengers to detect carrion, but that habitat characteristics did not affect exploitation of carrion more than other variables. These results highlight the potential importance of carrion for the foraging ecology of fishers, particularly during times of resource scarcity. Further research based on identifiable individuals is needed to quantify fitness consequences of scavenging for fishers, including possible negative effects of intraguild predation at carrion.
Efficacy of Using a Laser Device to Reduce Wild (Water)Birds Visits to the Free-range area of a Layer Farm Situated in an Avian Influenza Hotspot-region in the Netherlands

Free-range layer farms have a significantly higher risk of introduction of avian influenza viruses (AIV) compared to indoor layer farms. Wild water birds, natural reservoir of AIV, likely play a role in the transmission of AIV to chickens by contaminating the farms’ free-range area. The use of a laser as a repellent device for wild birds has been studied since the 1970s, in particular around airfields as bird-strike prevention, but its use at poultry farms to keep wild birds away from the surroundings of the poultry barn has not been studied. Part (1.5 ha) of the free-range area of a layer farm that directly boarded the poultry barn was equipped with a video-camera recording system. Visits of wild birds to this free-range study area were recorded for a month without and subsequently a month with a Class-III B laser in operation in the winter period. The laser was operated in the free-range study area between 5:00 PM and 10:00 AM, chickens were present in the free-range study area between 10:00 AM and 5:00 PM. The laser was operated in surrounding grass pastures between 10:00 AM and 5:00 PM. Mallards (Anas platyrhynchos) and Western barn owls (Tyto alba) visited the free-range study area between sunset and sunrise; Blackbirds (Turdus merula), Western yellow wagtails (Motacilla flava), White wagtails (Motacilla alba), Common Moor-hen (Gallimula chloropus) and Common kestrels (Falco tinnunculus) visited the free-range study area between sunrise and 10:00 AM. The overall (all bird species) efficacy of the laser for reducing the rate of wild birds visiting the free-range study area was 98.2 %. This efficacy was for birds of the Order Anseriformes 99.7 % and for birds of the Order Passeriformes 96.1 %. The overall exposure time of the free-range study area to wild birds (all species) was 617 times lower with the laser in operation compared to a situation in which the laser was not in operation. Exposure time to wild birds of the Order Anseriformes – known as bird flu risk species - was 2,320 times lower compared to the situation without the laser in operation. Summarizing, it can be concluded that the laser equipment used in this study was highly proficient in keeping wild birds – in particular wild ducks - away from the free-range study area of the layer farm.
The development strategy for sustainable livestock sector in small-islands region: a preliminary study on local cattle farming in Buru Island, Maluku Indonesia

Beef cattle are relevant to farm products for the livelihood of most small-scale farmers in Buru Island in Maluku Province. Other than being a significant source of income for farm households, the presence of cattle farming on that island is also strategic for the Indonesia livestock sector as Buru is one of the areas in the eastern part of Indonesia in which has the most significant population of local cattle. Nevertheless, in recent years, its population has been observed to be stagnant even tends to decline; hence many issues of its sustainability arise. The national government and stakeholders of livestock development positively should respond to this phenomenon. As a contribution to solving these issues, this article reports our preliminary study, which generally aims to propose feasible strategies for sustaining the presence of cattle farming and its population, especially in the context of islands region economic development. Our results show that current cattle farming on the island is in the state of survival; thus the strategy for the development must focus on moving to the better state through ensuring farmers' access to available natural resources and on improving public infrastructures, distributions, and logistics of the farm products. Recommendations for designing such strategies and policies are discussed briefly.
Protonation Dynamics in the K-Channel of Cytochrome c Oxidase Estimated from Molecular Dynamics Simulations

Proton transfer reactions are one of the most fundamental processes in biochemistry. We present a simplistic approach for estimating proton transfer probabilities in a membrane protein, cytochrome c oxidase. We combine short molecular dynamics simulations at discrete protonation states with a Monte Carlo approach to exchange between those states. Requesting for a proton transfer the existence of a hydrogen-bonded connection between the two source and target residues of the exchange, restricts the acceptance of transfers to only those in which a proton-relay is possible. Together with an analysis of the hydrogen-bonded connectivity in one of the proton-conducting channels of cytochrome c oxidase, this approach gives insight into the protonation dynamics of the hydrogen-bonded networks. The connectivity and directionality of the networks are coupled to the conformation of an important protein residue in the channel, K362, rendering proton transfer in the entire channel feasible in only one of the two major conformations. Proton transport in the channel can thus be regulated by K362 not only through its possible role as a proton carrier itself, but also by allowing or preventing proton transport via water residues.
A diffusion wavelets-based multiscale framework for inverse optimal control of stochastic systems

This work presents a multiscale framework to solve a class of inverse optimal control (IOC) problems in the context of robot motion planning and control in a complex environment. In order to handle complications resulting from a large decision space and complex environmental geometry, two key concepts are adopted: (a) a diffusion wavelet representation of the Markov chain for hierarchical abstraction of the state space; and (b) a desirability function-based representation of the Markov decision process (MDP) to efficiently calculate the optimal policy. An IOC problem constructed on a ‘abstract state’ is solved, which is much more tractable than using the original bases set; moreover, the solution can be obtained recursively in the ‘coarse to fine’ direction by utilizing the hierarchical structure of basis functions. The resulting multiscale plan is utilized to finally compute a continuous-time optimal control policy within a receding horizon implementation. Illustrative numerical experiments on a robot path control in a complex environment and on a quadrotor ball-catching task are presented to verify the proposed method.
Genetic typing and in silico assignment of smoked and fresh bushmeat sold on markets and restaurants in west-central Cte dIvoire

Poachers and bushmeat traders most of the time modify the wildlife materials before commercialization. Therefore, the morphological identification of species is no longer possible. However, accurate identification of the sale wildlife materials is essential for species identification, quantification and better conservation management. The aim of this study is to take advantages of specific gene sequences and in silico analysis to identify smoked and decapitated wildlife materials encountered on bushmeat markets and traditional restaurants in Center-Western Cote d’Ivoire. DNA from 352 bushmeat samples comprising 123 decapitated and smoked specimens was extracted, amplified by polymerase chain reaction (PCR) using the Cytb and COI primers and analyzed in silico. Up to 98.37% of the DNA from smoked bushmeat was successfully amplified. Assignment of Cytb and COI query sequences with reference sequences in the NCBI Genbank allowed to correct three misidentifications by traders. Thus, specimens identified as Heliosciurus sp, Phacochoerus aethiopicus africanus and Dendrohyrax dorsalis sylvestris by traders were assigned to Funisciurus sp, Tragelaphus scriptus, Crossarchus obscurus with 84.94, 100, 98.76% similarity respectively. Morphologically unidentifiable sample coded IP3CS1O was assigned to species Eidolon helvum with 99.53% similarity. The study shows the interest of DNA-based identification of bushmeat to circumvent misidentification for better management of wildlife biodiversity. Key words: smoked bushmeat, misidentification, genetic typing, in silico analysis, identification, biodiversity, wildlife conservation.
