More attention with less working memory: The active inhibition of attended but outdated information
Authors: Fu Yingtao , Zhou Yiling , Zhou Jifan , shen mowed , CHEN HUI
Published: September 2020

Attention has traditionally been regarded as a gateway to working memory, and almost all theoretical frameworks of attention and working memory assume that individuals always have a better memory for information that has received more attention. Here, we provide a series of counterintuitive demonstrations which show that paying more attention to a piece of information impedes, rather than enhances, the selection of this information into working memory. Experiments 1–5 provide converging evidence for an even weaker working memory trace of fully attended but outdated features, compared with baseline irrelevant features that were completely ignored. This indicates that the brain actively inhibits attended but outdated information to prevent it from entering working memory. Experiment 6 demonstrates that this inhibition processing is subject to executive control. These findings lead to a substantial reinterpretation of the relationship between attention and working memory.

Published: September 2020

Jugendliche nutzen vermehrt das Handy abends im Bett. Dies ist mit einem schlechteren Schlafqualität, längerer Einschlaflatenz und erhöhter Tagesmüdigkeit assoziiert. Besonders Jugendliche mit Schlafproblemen scheinen das Handy als Coping-tool einzusetzen. Daher sollte besonders in dieser Risikogruppe nicht nur die Dauer des Handykonsums, sondern auch die dahinterliegende Intention betrachtet werden. Dieser Fragebogen erfasst verschiedene zugrunde liegende Motive der Jugendlichen ihr Handy vor dem Schlafen zu nutzen. Dabei wird die Handynutzungsmotivation auf vier Subskalen erfragt: Einschlafhilfe, Vermeidung von Sorgen, Unterhaltung sowie Fear of Missing Out (FoMO). Die Einschätzung der Jugendlichen über die Gründe ihre Handynutzung werden mit leichten, schnell beantwortbaren Fragen erfasst, wodurch der Einsatz in der Forschung und in der Praxis ermöglicht wird.
Heard immunity: effective persuasion for a future COVID-19 vaccine
Authors: Duquette Nicolas
Published: September 2020

A survey experiment exposes treatment groups to four messages supporting future vaccination against COVID-19. These treatments emphasize either the risks of the virus or the safety of vaccination, to the respondent personally or to others. For a nationally representative sample, self-reported intent to vaccinate is not significantly different from the control for any message. However, there is a substantial divergence between white non-Hispanic respondents, whose response to all four treatments is close to zero, and non-white or His- panic respondents, whose intention to vaccinate is over 50% higher in response to a message emphasizing prosociality and the safety of others.
Application Essays and the Performance of Merit in US Selective Admissions

Published: September 2020

This paper was published in Poetics: https://www.sciencedirect.com/science/article/pii/S0304422X22000821. US colleges and universities are defined by their exclusivity, and the most prestigious schools reject most of those who apply. Yet these same schools also widely advertise their inclusiveness, encouraging students from all backgrounds to submit applications and highlighting evaluation protocols that identify many characteristics worthy of consideration for admission. We surface this paradox and use it as motivation to theorize a little studied component of college applications: personal essays. Drawing from cultural sociology, we posit that the commission and production of essays extolling applicant worth and worthiness is a ritual practice that instantiates an idea of merit that is broadly shared among those who submit applications to admissions-selective schools. We pursue this work empirically by observing essay prompt selections of 55,016 applicants to the University of California in 2016 and conducting human readings and statistical analyses of 3,519 unique essays. Results indicate that prompts and essays encompass a broad but bounded range of activities and experiences that selective schools and applicants consider meritorious. The entire process of application to selective US schools helps to reify a national cultural belief we call merit for all.

Published: September 2020

The hydrogeological condition of a region is determined by the type of lithology, morphology, and subsurface conditions where the condition is very helpful in the study of groundwater exploration. Especially when we encounter interesting geological conditions when the groundwater exploration in the karst area in which volcanic rocks are resulting from the activities of the active volcano in the past. Groundwater exploration at Ponjong area and surrounding does have its special characteristics, because it has 2 different rock characteristics where the northern part of the research area in the form of a karst area (limestone of Wonosari Formation) while the southern part is an area of ancient volcanoes with dominant volcanic rocks from Wuni Formation, As for the research on the above and subsurface research area where the research is conducted based on surface geology mapping, geoelectric data collection, and groundwater sampling. Geological mapping includes geomorphological data, stratigraphy, and geological structure. The aquifer system of the research area can be divided into two systems, inter-grain aquifer systems, and fracture aquifer systems. Overall quality groundwater in the research area is quite good. Ponjong District there are mining activities that have resulted in changes in the land use system in the area. This can cause changes in the water surplus in the area due to the changing catchment area.

Published: September 2020

Brza detekcija požara i precizna identifikacija njegovog mjesta od presudne su važnosti za uspjeh u borbi protiv šumskih požara. Vatrogasni tornjevi, odnosno motrionice, te njihovo pravilno korištenje, predstavljaju prvi korak u uspješnom otkrivanju šumskih požara u Turskoj. Cilj ove studije bio je izvršiti analizu vidljivosti vatrogasnih tornjeva postavljenih u planinskom mediteranskom šumskom dijelu Turske te procijeniti njihovu učinkovitost. Za zaštitu šumskog okoliša potrebno je utvrditi funkcionalnost i kapacitet ovih tornjeva. Područja koja su s tornjeva vidljiva i nevidljiva identificirana su pomoću geografskog informacijskog sustava i digitalnih podataka o nadmorskim visinama visoke rezolucije. U analizi vidljivosti, skeniranje je izvedeno rotacijom za 360 stupnjeva u radijusu od 18 kilometara od mjesta na kojem se nalazi vatrogasni toranj. Prometnice u ovoj regiji jedan su od elemenata koji se mogu koristiti u motrenju požara. Ljudi koji putuju ovim prometnicama mogu prijaviti šumske požare pomoću mobitela. U tom smislu, učinkovitost/djelotvornost tornjeva povezana je sa šumskim cestovnim prometom. Stoga je izvršena i analiza vidljivosti prometnica radi provjere mogućnosti motrenja s cesta. Iako su na ovom području, u kojemu su crnogorične vrste drveća poput brucijskog i crnog bora vrlo osjetljive na vatru postavljena 37 promatračka tornja, 40% šuma nalaze se u području koje nije vidljivo, a 15% tih šuma izložene su visokom riziku od požara. Preko 100 tisuća hektara područja osjetljivog na požare u ovoj regiji nije bilo moguće kotrolirati s tornjeva. Mreža tornjeva pokrivala je 56 % ukupnog područja i 59 % šumskog područja. Ljudi koji su koristili ceste doprinijeli su sustavu za detekciju požara s 11 % pa je na taj način, zajedno s tornjevima, 70 % šumskog područja u ovoj regiji bilo vidljivo. S druge strane, 59 % od 523 tisuća hektara šumskog zemljišta koji nisu bili vidljivi s cesta bili su uočljivi s tornjeva. Naglašeno je da je participativno ponašanje ljudi koji žive u šumama i koriste šumske prometnice važan dio sustava motrenja požara pri zaštiti okoliša.

Published: September 2020

Sustavnih istraživanja biološko-ekoloških obilježja cjelokupnog područja i same park-šume Hober nije bilo do sada. Strukturna obilježja sastojine nalazimo tek u Planu gospodarenja za park-šumu Hober (2006-2015). Šumarsku problematiku nalazimo u radu Vojinovića (1997). Dendrološka istraživanja imamo u radovima Denich i Draganović (1985), Vojinović (1997),Fabris (2001), Onofri (2002). Izostala je njegova cjelovita inventarizacija.
Današnje stanje park-šume Hober karakterizira njegova zapuštenost i neuređenost kako šumske vegetacije i dendrološko-hortikulturnih, tako i vrtno-arhitektonskih sadržaja. Prisutna je koncepcijska nedefiniranost cjelokupnog područja Hobera.
Park-šuma Hober u vegetacijskom smislu pripada šumskoj zajednici šuma alepskog bora i hrasta crnike (Querco ilicis – Pinetum halepensis Loisel 1971). Upravo iz razloga vegetacijske i strukturne neujednačenosti, postavljeno je 7 pokusnih ploha u samoj park-šumi, te još 4 izvan nje. Cilj je detaljnom vegetacijskom i strukturnom analizom izdvojiti pojedina područja, dati njihov opis i prikazati njihovo stanje, što se kasnije može upotrijebiti u svrhu zoniranja prostora.
Analizirana istraživanja pokazuju da u sloju drveća alepski bor prevladava na plohama 1,2,3 i 9; crnika na plohama 4 i 5 te obični čempres na plohama 6 i 7. U sloju grmlja najzastupljenija je lemprika koja dolazi na svim plohama. Zatim su tu širokolisna zelenika i tršlja. Iz tablice 2 vidimo da je na svim plohama pokrovnost vegetacijom potpuna osim na plohi 6, gdje je rijetka makija. Sloj drveća je prevladavajući osim na plohama 8, 10 i 11, gdje je prisutna makija. Zamjetno je da je kod razvijenih sastojina podjednako gust sloj drveća i grmlja. Tu odstupaju plohe 6 i dijelom ploha 9 te plohe 10 gdje je makija te ploha 11 koja je prirodna sukcesija šumske vegetacije na zapuštenim poljoprivrednim površinama. Osim kod makije imamo vrlo visok drvni volumen (drvna zaliha) koji se ovisno o razvoju sastojine kreće od 100 do čak 270 m3/ha. Broj stabala je isto vrlo velik i kreće se od 1000 do 2700 po ha. Svi ti podaci ukazuju na neuređenost i izostanak bilo kakvih uzgojnih radova.
Cilj ovog rada je istražiti vegetacijska, dendrološka, šumsko-uzgojna i strukturna obilježja cjelokupnog područja Hober. Ona su primarni pokazatelj stanje i dat će smjernice za njegovu buduću biološku i prostornu valorizaciju.

Authors: Cai Yongchen , Chen Xiuying , Xu Hujun
Published: September 2020

In the present study, three amide Gemini surfactants of different chain lengths were synthesized, namely N,N-bis-dodecyl-2,6-pyridinium dimethylamide propionate sodium (DLP-12), N,N-bis-tetradecyl-2,6-pyridinium dimethylamide propionate sodium (DLP-14) and N,N-bis-hexadecyl-2,6-pyridinium dimethylamide propionate sodium (DLP-16). Their chemical compositions and structures were characterized by FTIR, 1H NMR and mass spectrometry. Moreover, tensiometry, Langmuir monolayer and conductivity measurements were performed to investigate the micellization and chemical surface properties of the surfactants. The results of the characterization proved that the synthesis of DLP-12, DLP-14 and DLP-16 was successful. Among the investigated surfactants DLP-16 had optimum properties such as a higher emulsification ability as well as a lower surface tension. Furthermore, by calculating the critical packing parameter (CPP), the aggregation morphology of the DLP-12, DLP-14 and DLP-16 was also predicated in this study.

Published: September 2020

The present study is an investigation of the solubilising ability of natural and conventional surfactants saponin (sapindus saponin or reetha saponin), Rhamnolipids (RLs) and N-cetylpyridinium chloride (CPC) respectively via dye-surfactant interaction. The ionic dye Congo Red was examined by absorption spectroscopy method for the study. The dye interacted strongly with oppositely charged surfactant N-cetylpyridinium chloride in the pre-micellar concentration range and formed a stable dye-surfactant complex. The thermodynamic parameter, free energy change for all the systems was calculated at a constant temperature of 25°C. The ΔG0 value for N-cetylpyridinium chloride is found to be −33.269 kJ/mol while for saponin and rhamnolipids the values were −16.084 kJ/mol and −26.006 kJ/mol respectively. The values clearly indicate the efficiency of N-cetylpyridinium chloride surfactant compared to the other two surfactants. The present study aims to understand the dye solubilization in surfactant media in order to develop environmentally friendly, green and cost effective techniques.

Published: September 2020

The objective of this study was to develop an electronic controller for microclimate control in greenhouses, as well as to verify if the automated control system affects the productivity of two varieties of lettuce “Lactuca sativa”. The control system was developed based on the Atmega 2560 and compatible transducers. An experimental field analysis was carried out over a production cycle for two lettuce varieties. The experimental results showed that the designed equipment worked according to the implemented programming algorithm. However, the ventilation, nebulization and shading actuators did not control environmental variables, due to under sizing. The irrigation process was correctly controlled throughout the experimental period. The electronic controller promoted increase in the productivity of lettuce varieties. There was increase of 28% in total fresh weight; 10% in stem diameter; 7 and 8% in height gain and average diameter, respectively.
YIELD OF IRRIGATED CABBAGE SUBMITTED TO DIFFERENT SOURCES AND DOSES OF BORON
Authors: Leão Junior Laidson Alves , Buso Wilian Henrique Diniz
Published: September 2020

Cabbage is an important vegetable for food. The use of micronutrients, more specifically boron, is important for plant development and head formation. The study aimed to evaluate the agronomic performance and yield of the cabbage crop submitted to the application of different sources and doses of boron. The study was carried out in the Água Verde farm, located in Nova Glória-GO, under irrigation by a center pivot system. The soil tillage consisted of operation with a subsoiler and a disk harrow. The fertilization was carried out by applying 48 kg ha-1 of N, 360 kg ha-1 of P2O5, and 120 kg ha-1 of K2O, in the planting furrow. The seedling transplant took place on 06/22/2019. At 20 days after transplanting, topdressing fertilization was carried out, with 200 kg ha-1 of N and 200 ha-1 of K2O. A randomized block design with four replications in a 4x5 factorial scheme was used. Four boron sources (boric acid, borax, ulexite, and Sulforgan) and five boron doses (0.0, 0.5, 1.0, 2.0, and 3.0 kg ha-1) were evaluated. Each experimental plot consisted of four rows of five meters in length. The evaluations were carried out on the two central rows, with 0.50 m at each end. The variables analyzed were plant height, longitudinal diameter, transverse diameter, number of outer leaves, and yield (kg ha-1). There was no significant difference between the different boron sources evaluated. For the different boron doses applied, only the number of outer leaves did not obtain a significant regression. The application of boron at a dose of 1.8 kg ha-1 resulted in the highest cabbage-head yield, totaling 82.58 t ha-1.

Published: September 2020

This study aimed to analyze the effect of two planting spacing on dendrometric characteristics and basic wood density of eucalyptus clones. The experiment in the municipality of Jataí-GO, Brazil, used a randomized complete block design with three replications, in which the spacing (3.0 m x 2.0 m and 3.0 m x 3.0 m) were allocated to the plots and the clones (3335, 3336 and 3487) in the subplots. Diameter at breast height (dbh), total height (HT), total volume (VT), basic density (db), stem biomass (BS), leaf and branch biomass (BLB) and total biomass (BT) were evaluated. The data were submitted to analysis of variance, followed by the Tukey test for comparison of means at the 5% probability level. It was found that the dbh and VT characteristics were not influenced by the planting spacing nor by the clone types. The HT was influenced by the spacing with the highest value (26.3 m) verified in the spacing 3 m x 3 m. The db was influenced only by the clone types and the clones 3335 and 3487 presented the highest values (0.46 and 0.41 g.cm-3, respectively). The BS, BLB and BT were influenced only by clones with higher yields with clones 3335 and 3487. There were no significant interactions for any of the evaluated characteristics.

Published: September 2020

Conscious agricultural management, which aims to conserve natural resources, has been the target of contemporary agriculture. In this context, the reuse of water in deficit water depth in agricultural irrigation becomes a viable technique, and this work aimed to evaluate the effect of different irrigation depths with wastewater and soil mulching on the microbiological and postharvest characteristics of the Italian zucchini. The experiment was conducted in the field conditions with a randomized block design in a split-plot arrangement. Four irrigation depths (100%, 85%, 70%, and 55% of the estimated ETc from the Class A Evaporation Pan) and three types of soil mulching (rice husk, double-sided black and white polyethylene film, and uncovered soil) were analyzed. Texture, titratable acidity (TA), soluble solids content (ºBrix), pH, and the ºBrix:TA ratio of the Italian zucchini were analyzed, besides the microbiological analysis. The irrigation depth or soil mulching did not influence the pH of the Italian zucchini. The uncovered soil promoted higher titratable acidity to the Italian zucchini. The texture of the fruit, the soluble solids, and the ºBrix:TA ratio was influenced by the types of soil mulching and irrigation depths. The use of wastewater for drip irrigation reduces the effects of the microbial load on the crop.

The requirement for the study of blood parameters is determined by its physiological significance and changes that occur in different physiological and pathological conditions. The hematological profile is an important criterion that shows the physiological condition of animals. The physiological changes of blood in cows have been established concerning the conditions of keeping and feeding, hygienic parameters, in the dynamics of the dry season, in different seasons of the year, etcetera. We have not found any information on studies of the dynamics of blood parameters in pregnant animals, depending on their age, in the study of literary sources in recent years. The purpose of our work was to study the age-related dynamics of hematological blood parameters in cows during the dry period. Our studies aimed to determine the hematological indices of Holstein breed cows in the physiological course of the prenatal period during the dry period, depending on the number of deep calving. Control and experimental groups were formed on the principle of group-analogues (by breed, age, sex, physiological state, weight, milk productivity). Animals kept in typical rooms with satisfactory microclimate parameters (in winter) and at camps (in summer). Laboratory studies were carried out in the laboratory of the Dnipro State Agrarian and Economic University. Hematologic studies were performed according to the following indicators: erythrocytes, hemoglobin, color index, erythrocyte sedimentation rate, leukocytes, monocytes, lymphocytes, neutrophils with rod-like shape and segmented nucleus, basophils and eosinophils according to conventional methods. The results of our studies indicate that the lowest number of erythrocytes was detected in the cows of the sixth calving and the highest hemoglobin content, which led to the rise of the color index – in cows of the fifth pregnancy present the reverse tendency; increase to the maximum values of the number of leukocytes in cows of the third body (1.32 times), which is a reflection of the greater reactivity of the body of cows of this age group; a probable decrease (by 10.59 %, P < 0.05) of lymphocyte counts was found in sixth-calf cows, indicating a weakened immune response; also increased eosinophils almost 1.75 times (P < 0.05) compared to fifth pregnancy; the trend of a gradual decrease in the number of segmented neutrophils in calving cows is followed by a second to fifth pregnancy and a significant reduction in the number of stab neutrophils in cows of the fifth pregnancy of up to 1.33 %.

Milk contains key nutrients in optimal proportions, which makes it to be an important component of the human diet. Despite the fact that consumers receive with milk a significant amount of readily available nutrients, milk can be a source of dangerous factors of chemical and biological origin. The level of physiological hormones found in milk is not a limiting factor and is studied solely for scientific purposes. However, milk hormones can have a negative effect on the health of consumers. Based on this, the aim of this work was to study the concentration of triiodothyronine and thyroxine in colostrum, milk and blood plasma of cows at different stages of lactation. The secretion of the mammary gland and blood plasma of cows of Ukrainian black-and-white dairy breed, in their 2nd–5th lactations with milk yield 5100–5700 kg of milk per previous lactation was the object of the study. The concentration of triiodothyronine and thyroxine using enzyme-linked immunosorbent assay was investigated in withdrawn samples. The obtained data indicates that the highest level of secretion of iodine-containing thyroid hormones with milk is observed on 1st–4th days of lactation. Thereafter, the concentration of hormones in milk statistically significant decreases by 2.8–3-fold (P ˂ 0.001) till 30–40th day of lactation. The high concentration of iodine-containing hormones in colostrum allows to enhance metabolic processes in calves. Studies of the concentration of thyroid hormones in the blood plasma of cows showed a gradual increase from the beginning of lactation till 10th–14th and then till 30th–40th days of lactation. By 10th–14th days we observed 2.2-fold growth of triiodothyronine level (P ˂ 0.001), and till 30th–40th days this parameter has increased by another 12.5 %. The level of thyroxine on 10th–14th days of lactation was higher, compared to such in the beginning of lactation by 62.2 % (P ˂ 0.001), and by 30th–40th day increase was by 40.9 %. The main reasons for such changes are the formation of lactation dominant, the discharge of hormones secreted by the breast and the stimulation of metabolic processes during lactation. The prospects of further research lie in investigation of the dependence of triiodothyronine and thyroxine levels in the secretion of the mammary gland on productivity, breed, age and diet of animals.

The ectoparasites Ctenocephalides felis and Ctenocephalides canis are distributed worldwide and are the most common species of fleas that parasitize domestic carnivores. As active vectors of infectious and invasive diseases, fleas of the genus Ctenocephalides are of great epidemiological importance. Intensive growth of the number of dogs, violation of sanitary and hygienic conditions of their keeping, especially in large cities, as well as global warming significantly affect the epizootic situation regarding ctenocephalidosis. The aim of the work was to study the features of age susceptibility of domestic dogs in the city of Poltava (Ukraine) to Ctenocephalides spp. Indicators of infestation of animals with the causative agent of ctenocephalidosis depending on their age and housing conditions were determined. Studies have shown that dogs of any age are prone to flea infestation. Ctenocephalidosis is diagnosed in animals of all ages. At the same time, the age dynamics of defeat of dogs by parasitic insects under different conditions of their keeping differed significantly. The average extensity and intensity of the invasion was lower in animals kept in apartments (26.47 %, 10.82 specimens/head) compared to animals kept in the private sector (76.21 %, 22.71 specimens/head). The highest rates of flea infestation of the genus Ctenocephalides were found in dogs aged one to six years (37.10–45.45 %; 10.45–15.91 specimens/head) – for housing, as well as in young animals up to 12 month of age (84.03–90.36 %; 22.78–32.56 specimens/head) – for aviary maintenance. Less infested were dogs under 6 months of age (11.26 %; 5.43 specimens/head) and older 6-year-olds (16.28 %; 8.54 specimens/head) – for housing, as well as dogs aged one to six years (53.54–75.38 %; 11.63–20.24 specimens/head) – for aviary keeping. The results obtained regarding the age dynamics of infestation of domestic dogs with fleas of the genus Ctenocephalides can be taken into account when carrying out measures to control and prevent ctenocephalidosis in dogs under different conditions of their content.

Published: September 2020

Objetivo: Medir el nivel de competitividad en la producción de fresas en México para el periodo de 1980 a 2019 y con ello, generar estrategias que tengan un impacto positivo en el aumento de la especialización

Diseño/metodología/enfoque: la metodología consiste en la aplicación de tres indicadores relacionados con la competitividad y especialización a nivel macroeconómico y mesoeconómico como lo son: el cociente de localización, el Indicador de Especialización Internacional de Lafay y, el Índice de Ventaja Comercial Revelada de las Exportaciones para el periodo que comprende de 1980 a 2017, para cada uno de los estados de la república mexicana y en comparación con Estados Unidos.

Resultados: la producción de fresas en México es especializada ya que cuenta con ventajas comparativas que los diferentes estados aprovechan y las cuales permiten al país, posicionandose como exportador neto y con un importante grado de importancia dentro de las exportaciones de fresa del país hacia el mercado Estadounidense.

Limitaciones en el estudio/implicaciones: no se encontraron limitaciones en termino de los datos obtenidos de las fuentes de información secundaria necesarios para la aplicación de la metodología. Sin embargo, los resultados se limitan al análisis de un solo aspecto que impacta en la competitividad tal como lo es el comercio y sería interesante estudiar más variables que impactan a la especialización y por ende mejoran la competitividad.

Hallazgos/conclusiones: a pesar, de los resultados favorables en el calculo de los indicadores es necesario aplicar estrategias que favorezcan el incremento en la especialización y competitividad de la producción de fresas en México e incrementen la rentabilidad de los productores.

Strava Metro data are used in bicycle planning, but there are concerns it overrepresents fitness activity. The data include a commute label, but spatial patterns of commuting versus recreational ridership are underexplored. Using spatial regression, we compare associations of Strava ridership by trip type. Commuting was associated with areas with more on-street infrastructure, universities, and higher bicycle crash density. Recreational ridership was higher in areas with older populations, more hills and major roads, and lower intersection density. Both trip purposes tended to be in areas with regional trails, off-street infrastructure, higher bicycle mode share, bridges, and proximity to the ocean.

The vulnerability identification of coastal areas in this study consisted of the level of danger (earthquake and tsunami), physical vulnerability and non-physical vulnerability. Determination of hazard level using modeling based on seismic history in the subduction zone south of Bali, while analysis of the level of physical and non-physical vulnerability is used Descriptive analysis and Analytical Hierarchy Process (AHP). The analysis process will determine the ranking used as an indicator of decision making to create a vulnerability level map in the research area through the Geographic Information System (GIS) with three levels, namely high, medium and low. In this study also formulated coastal area management policies in the perspective of disaster mitigation using SWOT analysis. The results of the analysis show that four kelurahan in Badung Regency which have high levels of vulnerability are Kuta, Tuban, Kedonganan and Tibubeneng. While the seven kelurahan in the medium level of vulnerability are Jimbaran, Benoa, Tanjung Benoa, Legian, Seminyak, Canggu, Dalung, and the four kelurahan with low levels of vulnerability are Pecatu, Ungasan, Kutuh and Kerobokan. In general the research area is at a high to moderate level of vulnerability, this shows that a comprehensive disaster mitigation effort is needed by implementing several strategies formulated, including 1) developing disaster resilient village programs by establishing disaster risk reduction forums and volunteer training villages for disaster mitigation, 2) maximizing community knowledge in disaster and mitigation to cope with high earthquake and tsunami hazard levels, 3) implementing regional regulations on disaster mitigation based spatial planning effectively in controlling disaster risk areas and utilizing green lines as evacuation routes and meeting point.
