Trust among Peers on Peer-to-Peer Marketplaces as AirBnB

E-Commerce ist ein wachsender Wirtschaftssektor. Im Gegensatz zu traditionellem Kommerz, kennen sich Vertragspartner/innen bei Onlinegeschaften meist nicht personlich und stehen sich auch nicht personlich gegenuber. Vertrauen muss somit uber die physische Distanz hinweg aufgebaut werden und die Anonymitat des Internets uberwinden. Auf Peer to Peer-Marktplatzen im Internet kommt noch hinzu, dass die Konsumenten Guter nicht von professionellen Geschaftspartnern erwerben, sondern von Ihresgleichen. Daher ist anzunehmen, dass Vertrauen auf Peer to Peer-Marktplatzen eine entscheidende Rolle spielt und anders gebildet wird als in traditionellem Kommerz. Diese Studie untersucht die Einflussfaktoren Vertrauensdisposition, Erfahrung mit AirBnB und Ahnlichkeit zwischen Teilnehmer/in und Peer-Anbieter/in auf Vertrauen in Peers auf Peer to Peer-Marktplatzen am Beispiel AirBnB mit Hilfe einer Online-Simulations-Studie. Der Literatur zufolge wurde angenommen, dass alle drei Einflussfaktoren (Vertrauensdisposition, Erfahrung mit AirBnB und Ahnlichkeit) in einem positiven Zusammenhang mit Vertrauen stehen. In Anlehnung an die Theory of Reasoned Action wurde angenommen, dass Vertrauen als Mediator zwischen den Einflussfaktoren und der Intention eine Ferienwohnung von einem bestimmten Peer wirkt. Die Ergebnisse dieser Studie bestatigen den positiven Einfluss von Vertrauensdisposition und Ahnlichkeit auf das Vertrauen in Peers. Entgegen der literaturgeleiteten Vermutung, zeigte Erfahrung mit AirBnB keinen signifikanten Einfluss auf Vertrauen. In Ubereinstimmung mit der Theory of Reasoned Action zeigten die Ergebnisse, dass Vertrauen als Mediatorvariable zwischen den Einflussfaktoren Vertrauensdisposition und Ahnlichkeit und der Intention von einem bestimmten Peer zu buchen wirkt.
SEF Working paper : 14 / 2015 Understanding peer effects-on the nature , estimation and channels of peer effects

This paper estimates peer effects in a university context where students are randomly assigned to sections. While students benefit from better peers on average, low-achieving students are harmed by high-achieving peers. Analyzing students’ course evaluations suggests that peer effects are driven by improved group interaction rather than adjustments in teachers’ behavior or students’ effort. We further show, building on Angrist (2014), that classical measurement error in a setting where group assignment is systematic can lead to substantial overestimation of peer effects. With random assignment, as is the case in our setting, estimates are only attenuated.
Tools of oppression and control in counseling: Making the invisible, visible

In the last few years the literature in mental health work and ethnic minorities, seems to reflect the need to take in consideration the effects of oppression and in particular the after-effects of colonialism during the counseling process. However, the tools used to gain power and control over others, as well as the stages to reach a colonized state has not been addressed. Therefore, this manuscript intends to name both the tools of oppression as well as the stages of colonization in an attempt to raise consciousness, critical thinking and personal liberation, as an outcome of the counseling process, a process that according with Freire (2000) and Martin Baro (1998) lead to change. Implications for counseling and clinical practice issues are included, as well as future directions for research and practice.

The use of aerial and close-range photogrammetry in the study of dinosaur tracksites: Lower Cretaceous (upper Aptian/lower Albian) Molfetta ichnosite (Apulia, southern Italy)

Accurate mapping and three-dimensional models are crucial for studying dinosaur tracks and tracksites at different scales. The use of small Unmanned Aerial Vehicles (UAVs) for mapping and three-dimensional modelling is becoming increasingly com-mon, allowing the capture of high-resolution images comparable to those obtained by terrestrial laser scanners and manned aerial photogrammetry, but with reduced working costs and rapid execution times. The Lower Cretaceous (upper Aptian/lower Albian) used as a test area to evaluate the results of UAV based photogrammetry. We used two different drones having different technical features and for which we set different flight parameters. Ground-based photogrammetry on single footprints was also performed, in the light of the recent introduction of high-resolution digital cameras and powerful processing software, with the aim to evaluate its impact on ichnological, ichnotaxonomical, and ichnosystematic analyses. The accuracy of three-dimensional models, digital elevation models, and orthophotos generated by UAV images is extremely high and allows for rapid mapping and description of vast and/or hardly accessible tracksites with higher accuracy than that obtained from traditional field data or from digital airphotos. By coupling ground- and aerial-based photogrammetry, ichnologists can rapidly obtain consis-tent and affordable digital models useful to study dinosaur tracksites both at the meso-(track) and macroscale (ichnosite). The adoption of aerial and close-range photogrammetry will allow for the rapid production of data with sustainable costs that can be used both by specialists and as a means of conservation and dissemination of knowledge to the public.
3D ARCHITECTURAL VIDEOMAPPING

3D architectural mapping is a video projection technique that can be done with a survey of a chosen building in order to realize a perfect correspondence between its shapes and the images in projection. As a performative kind of audiovisual artifact, the real event of the 3D mapping is a combination of a registered video animation file with a real architecture. This new kind of visual art is becoming very popular and its big audience success testifies new expressive chances in the field of urban design. My case study has been experienced in Pisa for the Luminara feast in 2012.
Production of cystosori of Spongospora subterranea (Walk.) Lagerh f. sp. subterranea Tomlinson during a potato crop cycle in three soil types

The powdery scab is caused by the protist Spongospora subterranea (Walk.) Lagerh f. sp. subterranea Tomlinson, which is an obligate parasite that replicates in roots and tubers of potato (Solanum tuberosum). This replication results in resistant structures which are denominated cystosori. Production of cystosori was investigated in the potato variety Diacol Capiro, which was cultivated in three types of soil (Inceptisol, Entisol, and Andisol) that were infested with cystosori. Concentration of cystosori was determined at planting (Initial), at plant senescence (Harvest), and at plant disintegration (Postharvest). The experimental design was completely randomized with two treatments and three levels each. Soil type with the levels Inceptisol, Entisol and Andisol, was one treatment; and the sampling time with the initial, harvest and postharvest, was the other. Additionally, a test of simple regression to analyze correlation of the initial and final concentration of cystosori was performed. In all types of soil, cystosori concentration increased significantly (P ≤ 0.05) from planting to postharvest; the mean increase was 48%. There was no significant (P ≤ 0.05) difference among types of soil at any time sampling. The final concentration of cystosori (Postharvest) was significantly (P ≤ 0.05) which correlated with the initial concentration of cystosori (Initial). These results suggest that cystosori concentration can have a substantial increase after a single potato crop cycle, and harvest residuals, such as contaminated tubers, can contribute to this increase.
Variation in Flight Morphology in a Damselfly with Female-Limited Polymorphism

Background: Female-limited colour polymorphisms occur in many species of dragonflies and damselflies. Often one female morph appears male-like in coloration (androchromes) whereas one or more others are distinct from males (gynochromes). These androchromes are hypothesized to be male-mimics, thereby avoiding the harassment of excessive male mating attempts. Organism: The damselfly Ischnura ramburii, Rambur’s forktail, is a widespread New World species with androchrome and gynochrome females. It was introduced to the Hawaiian Islands in the mid-1970s and females were thought to be exclusively gynochromatic there. Questions: How do males and females differ in their flight apparatus? Do females with different colour morphologies also differ in flight morphology? Hypothesis: Because male-like coloration is sometimes associated with male-like flight behaviours, androchrome females should have more male-like wings than gynochrome females. Methods: We caught individuals of I. ramburii in the field from seven populations on three of the Hawaiian Islands and three populations in Texas (part of its native range). Using digitized wing and body images, we compared body size, wing size, and wing shape between sexes, between female morphs, and among geographic regions. Results: Male I. ramburii are smaller than females and have smaller, more slender wings. Although androchromes are absent from the Big Island of Hawaii, both androchrome and gynochrome females are common on Oahu and Kauai. Androchrome females are indistinguishable from gynochrome females in all aspects of their flight apparatus except for forewing size, which is smaller than that of gynochromes and thus more-male like. Wing shape and size vary geographically. Bodyand wing-size differences between males and females are consistent across regions, although the degree and direction of sexual dimorphism in wing

Downward continued multichannel seismic refraction analysis of Atlantis Massif oceanic core complex, 30°N, Mid‐Atlantic Ridge

Detailed seismic refraction results show striking lateral and vertical variability of velocity structure within the Atlantis Massif oceanic core complex (OCC), contrasting notably with its conjugate ridge flank. Multichannel seismic (MCS) data are downward continued using the Synthetic On Bottom Experiment (SOBE) method, providing unprecedented detail in tomographic models of the P‐wave velocity structure to subseafloor depths of up to 1.5 km. Velocities can vary up to 3 km/s over several hundred meters and unusually high velocities (∼5 km/s) are found immediately beneath the seafloor in key regions. Correlation within situand dredged rock samples, video and records from submersible dives, and a 1.415 km drill core, allow us to infer dominant lithologies. A high velocity body(ies) found to shoal near to the seafloor in multiple locations is interpreted as gabbro and is displaced along isochrons within the OCC, indicating a propagating magmatic source as the origin for this pluton(s). The western two‐thirds of the Southern Ridge is capped in serpentinite that may extend nearly to the base of our ray coverage. The distribution of inferred serpentinite indicates that the gabbroic pluton(s) was emplaced into a dominantly peridotitic host rock. Presumably the mantle host rock was later altered via seawater penetration along the detachment zone, which controlled development of the OCC. The asymmetric distribution of seismic velocities and morphology of Atlantis Massif are consistent with a detachment fault with a component of dip to the southeast. The lowest velocities observed atop the eastern Central Dome and conjugate crust are most likely volcanics. Here, an updated model of the magmatic and extensional faulting processes at Atlantis Massif is deduced from the seismic results, contributing more generally to understanding the processes controlling the formation of heterogeneous lithosphere at slow‐rate spreading centers.
National survey of body mass and dietary behaviour for middle school, high school and university students

Introduction: According to a report from the European Association for the Study of Obesity (EASO), there are 200 million overweight and obese school children in the world today. To assess body mass for students in Poland, in middle schools, high schools and universities, according to growth charts and BMI. Also, to investigate the link between chosen dietary habits and the risks to these subjects of being overweight and obese. Material and methods: The 13,566 subjects surveyed in 2011 consisted of middle school (3,548), high school (4,423) and university (5,595) students. The two younger groups received a questionnaire that had been devised by GIS (Poland’s Chief Sanitary Inspectorate) based on one previously used for the WHO’s global school-based student health survey (GSHS). An electronic questionnaire was used for the university students, made available at a designated internet site. Results: Overweight rates of 13%, 11% and 14% were found in students from middle-school, high-school and university. Overall obesity rates were 3%. Most subject ate three meals daily, although almost 1 in 5 said they ate only 1 to 2 meals daily. Snacking between meals was admitted by 84%, 89% and 89% of students, respectively, whereas corresponding rates for nighttime eating were 24%, 37% and 36%. Conclusions: The survey demonstrated that overweight status, according to growth charts and BMI, occurs in 13%, 11% and 14% of subjects in each student group, respectively. Overall, obesity accounts for 3% of respondents. Numerous instances of abnormal dietary habits were found, highlighted by irregular mealtimes, between-meal snacking and nighttime eating.
Evaluating the Security of Smart Home Hubs

Evaluating the Security of Smart Home Hubs Steven A. Christiaens School of Technology, BYU Master of Science The goal of this research is to improve the security of smart home hubs by developing a standard against which hubs can be evaluated. This was done by first reviewing existing standards, guides, and collections of best practices. I determined that adapting or extending an existing standard was the best way to proceed. Potential candidates were selected, and after thorough comparison, I chose to extend the OWASP Application Security Verification Standard (ASVS). Extensions were composed of additional security requirements to address smart home hub functionality not covered by the existing requirements of the ASVS. These additional requirements were developed based upon existing best practices and are referred to as the Smart Home Extensions. Where a best practice or guidance did not yet exist for a particular hub functionality, guidance from related fields was adapted. The entire set of Smart Home Extensions were reviewed by industry experts, updated based on feedback, and then sent on for further peer review. Four smart home hubs – VeraLite, Wink, Connect, and SmartThings – were evaluated using the ASVS with the Smart Home Extensions. The evaluation uncovered security vulnerabilities in all four hubs, some previously disclosed by other researchers, and others new. Analysis of the evaluation data suggests that authentication is a common problem area, among others. Based on the performance of the hubs and the data collected, I suggest that the ASVS and Smart Home Extensions can be an effective tool to provide insight into the security posture of smart home hubs.
DSPIC-BASED IMPEDANCE MEASURING INSTRUMENT

An implemented impedance measuring instrument is described in this pape r. The device uses a dsPIC (Digital Signal Peripheral Interface Controller) as a proces sing unit, and a DDS (Direct Digital Synthesizer) t o stimulate the measurement circuit composed by the reference i mpedance and the unknown impedance. The voltages across the impedances are amplified by programmable gain instrumentation amplifiers and then digitized by analog to digital converters. The impedance is meas ured by applying a seven-parameter sine-fitting algorithm to estimate the sine signal parameters. The dsPIC communicates through RS-232 or USB with a computer, where the measurement results can be analyzed. The device also has an LCD to display the measurement results .
Mitochondrial Respiratory Chain Enzymatic Activities on Skin Fibroblasts in Patients With Mutant Glucocerebrosidase and PARK2 Genes

Background: Impairments of mitochondrial respiratory chain have been observed in skin fibroblast of patients with sporadic Parkinson’s disease (PD) and PARK2 mutations. This study assesses enzymatic activity of mitochondrial respiratory chain in skin fibroblasts of Thai PD patients with glucocerebrosidase (GBA) and PARK2 mutations. Methods: Skin fibroblasts were obtained from 14 individuals including four mutant GBA alleles, three mutant PARK2 alleles, and seven PD patients without mutations. Five age-matched healthy controls were recruited. Activities of complex I - V were assessed using enzyme-linked immunosorbent assay, and normalized with citrate synthase activity. All measurements were performed in triplicate. Results: Complex V activity seemed to be lower in PD patients than controls. Among patients, activities of complexes I, II, IV and V seemed to be lower in the mutant group than those without mutation. Among patients with mutations, the mutant GBA group showed slightly lower activities of complexes II, IV, and V than the mutant PARK2 group. Conclusions: A skin fibroblast culture may be a useful tool to investigate how GBA mutation leads to impairment of the energetic metabolism in patients with PD.

Molecular recognition of histidine-tagged molecules by metal-chelating lipids monitored by fluorescence energy transfer and correlation spectroscopy

Complex binding of proteins by metal-chelating lipids via surface-exposed or protein-engineered histidines provides an universal and powerful concept for the orientation and two-dimensional crystallization of proteins at self-organized interfaces. To demonstrate pair formation between individual histidine-tagged molecules and chelator lipids on the molecular level, we have synthesized novel lipids bearing both a Ni−NTA chelator and a fluorescent group. These lipids serve as spectroscopic probes to visualize directly the molecular recognition of fluorescence-labeled histidine-tagged peptides by metal-chelating lipids using fluorescence resonance energy transfer (FRET). The molecular docking to chelator lipids assembled in mono- or bilayers is highly specific, revealing only 3% unspecific adsorption and a binding constant of 3 μM. The affinity constant was confirmed by fluorescence correlation spectroscopy (FCS) on single molecules, where the ratio of lipid-bound to free was analyzed by their intrinsically .
A Study of Neural Network Learning-Based Recommender System

--------------------------------------------------------ABSTRACT----------------------------------------------------------A recommender system sorts and recommends the information which meets personal preferences among a huge amount of data provided by e-commerce. In particular, collaborative filtering (CF) is the most widely used technique in these recommendation systems. This method finds neighboring users who have similar preferences with particular users and recommends the items preferred by the former. This study proposes a neural network learning model as a new technique to find neighboring users using the collaborative filtering method. This kind of neural network learning model takes care of a sparseness problem during the analysis stage among those related with target users. The proposed method was tested with MovieLens data sets, and the results showed that precision improved by 6.7%.
Photosensitized Oxidation of 9,10-Dimethylanthracene on Dye-Doped Silica Composites

A series of cationic dyes, methylene blue (MB), safranin O (SF), toluidine blue (TB), and neutral red (NR), were successfully incorporated into a silica matrix by using ultrasound irradiation during the Stober process. Several analyses were performed, including scanning dynamic light scattering (DLS), electron microscopy (SEM), nitrogen physisorption, FTIR spectroscopy, UV-vis, and diffuse reflectance spectroscopy. The entrapped dyes on silica were evaluated in singlet oxygen (1O2) generation under visible light irradiation, by means of the photosensitized oxidation of 9,10-dimethylanthracene (DMA). According to the results, the photocatalytic performance of the silica composites was improved, and the leakage of the dye from the particles was suppressed. Among these four different types of dye-doped silica composites, the SiO2-SF composite showed the most efficient delivery of 1O2.

A Comparative Study of Automatic Text Categorization Methods Using Arabic Text

There are several researches and procedures for classifying Arabiclanguage texts that are based mostly on different environments. This lack of dependence on a unified standard (such as a unified dataset) makes it hard to determine the most accurate technique for classification. In this paper, we study and analyze the classification algorithms based on a unified environment and a different dataset with the included challenges faced by these algorithms to demonstrate their effectiveness and accuracy with a large dataset.
