Are hotel stay characteristics influencing guests’ environmental behaviour? Predicting water conservation habits

ABSTRACT Managing water consumption is of vital importance in the sustainable development of the tourism industry. In the hotel sector, guests’ good water consumption habits result in greater conservation, leading to more efficient sustainable management of the resource. Sociodemographic profile has been identified as a key factor in explaining the frequency of guests’ displaying good water consumption habits in hotels. However, variables related to guest stay could also be fundamental in predicting guests’ environmental behaviour. Data were collected from 648 surveys administered to guests at a hotel that excels with its good practices in water consumption and management. A generalized linear model with common sociodemographic variables and two stay characteristics variables (length of stay and loyalty) were applied to predict guests’ water conservation habits. Unlike loyalty, the results show that length of stay significantly and positively influenced water conservation habits. In this sense, guests who stay longer at the hotel tend to display greater water conservation habits. In accordance with this, hotel sector strategies aimed at promoting longer stays may prove useful in achieving maximum efficiency in water conservation management.
Mitochondrial genome of Tesseropora rosea: molecular evidence for non-monophyly of the genus Tetraclita

Abstract The complete mitochondrial genome of Tesseropora rosea (Tetraclitidae) was presented. The genome is a circular molecule of 15,330 bp, which encodes 13 PCGs, two rRNA genes, and 22 tRNA genes. The length of all non-coding regions is 768 bp, with the longest one speculated as the control region (255 bp), which is located between 12S rRNA and trnK. Phylogenetic analysis based on mitochondrial PCGs shows that T. rosea is nested within the genus Tetraclita, more closely related to Tetraclita japonica than to Tetraclita rufotincta or Tetraclita serrata. Thus, the monophyly of the genus Tetraclita is not supported.
Beamforming‐based random access protocol for massive MIMO systems

Massive multiple‐input multiple output (MIMO) systems provide a promising technology for the next generation of wireless communication systems (5G). In the present research, a novel random access (RA) protocol is proposed based on the beamforming properties to admit as many user equipment (UE) as possible, enhance the system performance, and manage the limited number of orthogonal pilots simultaneously. First of all, the proposed RA protocol is studied theoretically to find out formulas for average number of users who will have access to the base station (BS). The result shows the same number of UEs can access the BS as conventional protocols such as multichannel RA solutions. However, in contrary to the conventional protocols, the proposed protocol guaranties that the UEs are located in separate locations, thus, the signal to interference ratio (SINR) of the admitted users are enhanced in multiuser MIMO data transmission phase. A series of enhancements are then proposed to save the orthogonal pilots and to increase the average admitted users significantly. It is shown that, using our novel protocols, we can almost admit as many users as the number of antennas in the BS, using only a fraction of orthogonal pilots needed in conventional protocols.
Alliance portfolio management capabilities, corporate entrepreneurship, and relative firm performance in SMEs

ABSTRACT This article shows how small- and medium-sized enterprises (SMEs) can enhance the level of corporate entrepreneurship through alliance management capabilities. The findings from a sample of 272 suppliers to the mining industry demonstrate that the constituting dimensions of alliance portfolio management capability (that is, partnering proactiveness, relational governance, and portfolio coordination) positively affect corporate entrepreneurship. Moreover, corporate entrepreneurship mediates the effects of these dimensions on firm performance. These findings improve our understanding of how organizational capabilities enable SMEs to mitigate their lack-of-resources problem while engaging in interfirm relationships to better utilize corporate entrepreneurship for increasing firm performance.
AUTOMOBILE PLATFORM CAPITALISM: A VEHICULAR HISTORY OF THE DIGITAL ECONOMY

This paper takes up a variant on the meaning of the term platform – the base structure of an automobile – to explore the discursive and labour origins of what we now call platform capitalism. The argument made in this paper is that while Nick Snricek (2016) mentions Toyotism in passing in his Platform Capitalism, there is a much more profound relationship between Toyota – and Japanese “lean manufacture” or just-in-time automobile production in general – and the platform economy than has previously been appreciated. Based on extensive historical research on the automobile industry discussions in North America and Japan, and the platform managerial literature that emerged from it, this paper will offer an alternate genealogy of platform capitalism and the managerial theory that buttresses it, with the aim to ultimately offering a distinct mode of analysis of both platform theory and platform capitalism.
Accounting Implications of Blockchain - A Hyperledger Composer Use Case for Intangible Assets

Blockchain technology, commonly associated with bitcoin cryptocurrency, attracted large amounts of investment, attention, and analysis. In addition to attracting the attention of investors, speculators, and regulators, implications for financial practitioners and organizations are increasingly apparent. Financial transactions, property transfers, audit and attestation services, supply chains, and numerous other areas of industry are continuing to integrate blockchains into operations. This paper bridges the gap between the technical concept of blockchain andrelevance to the accounting field. By distilling technical components of blockchain into understandable components, practitioners and other users of this research are poised to better understand, explain, and apply salient concepts. This paper proposes a Hyperledger Composer use case method through which practitioners and researchers can familiarize themselves withblockchain concepts using an interactive demonstration of an accounting integration for intangible assets. Addressing the growing need for increased awareness, this paper builds anecessary skillset with blockchain technology and applications.
A learning-based harmonic mapping: Framework, assessment, and case study of human-to-robot hand pose mapping

Harmonic mapping provides a natural way of mapping two manifolds by minimizing distortion induced by the mapping. However, most applications are limited to mapping between 2D and/or 3D spaces owing to the high computational cost. We propose a novel approach, the harmonic autoencoder (HAE), by approximating a harmonic mapping in a data-driven way. The HAE learns a mapping from an input domain to a target domain that minimizes distortion and requires only a small number of input–target reference pairs. The HAE can be applied to high-dimensional applications, such as human-to-robot hand pose mapping. Our method can map from the input to the target domain while minimizing distortion over the input samples, covering the target domain, and satisfying the reference pairs. This is achieved by extending an existing neural network method called the contractive autoencoder. Starting from a contractive autoencoder, the HAE takes into account a distance function between point clouds within the input and target domains, in addition to a penalty for estimation error on reference points. For efficiently selecting a set of input–target reference pairs during the training process, we introduce an adaptive optimization criterion. We demonstrate that pairs selected in this way yield a higher-performance mapping than pairs selected randomly, and the mapping is comparable to that from pairs selected heuristically by the experimenter. Our experimental results with synthetic data and human-to-robot hand pose data demonstrate that our method can learn an effective mapping between the input and target domains.
A Lógica da Ciência e o Falibilismo Epistemológico do Logical Syntax de Rudolf Carnap

This article aims to analyze an important moment of transformation in the Rudolf Carnap’s work. The moment we are concern about refers to the publication of The Logical Syntax of Language in 1934 and the modifications refers to author’s logical analysis structure and metatheoretical positions. Specifically, in the methodological scope, Carnap develops the logical syntax as the structure of logic-linguistic analysis and elaborates the Logic of Science as the field of Philosophy of Science; in the metatheoretical scope, Carnap substitutes Aufbau’s methodological foundationalism for epistemological fallibilism. In the face of such changes, Coffa, a central reference of carnapian revisionism, claimed that Carnap’s empiricism with the syntactic ascension and the loss of protocol sentences incorrigibility status was led to the empirical basis’ conventionality and epistemological relativism. Therefore, our aim in this article is to present a Logical syntax’s consistent interpretation as well as to evaluate and critically discuss Coffa’s interpretation in The semantic tradition from Kant to Carnap.
From commitment to expressionism: a survey on the changing concept of photography in Iran

This paper examines the evolution of the concept of photography in Iran during the two decades following the 1979 Islamic revolution and its relationship to a changing political discourse during that period. Since the state became a dominant player in culture and the arts during the post-Islamic revolutionary era, this paper puts the evolution of the concept of photography into a socio-political context. Using Discursive Institutionalism as a theoretical framework, we examine Iranian photographers’ ideas on photography as well as the discourses that affected photography organisations, revealing the forces driving changes in how photographic work was conceived. The first decade following 1979 the Islamic revolution was marked by eight years of war, and photography was purposed to produce factual documents, leaving no room for picture-making, manipulation or self-expression. Meanwhile due to the revolutionary and leftist agenda set forth by the Mir-Hussein Mousavi administration (1981–1989), photography was formulated as a commitment to depict social deprivation and the difficulties in achieving social reforms. However, with the liberalising ideas introduced during Hashemi Rafsanjani’s administration (1989–1997), the concept of photography began to change. Photographic work became less an expression of political commitment to being seen as a form of self-expression that valued formalism and image-making. In other words, the changing political discourses during this period mark a shift from ‘taking’ to ‘making’ photographs. The intellectual opening In Iranian society that began in the early 1990s both paved the way for a more theoretical approach to photography as well as growing diversity in the organisation of photographic work. In particular, the more liberal attitude of the Rafsanjani administration resulted in a significant increase in the number of journals, newspapers and publications that provided a market for more imaginative photography, and a fluorescence of picture ‘making. ’

UKLANJANJE NESTEROIDNIH ANTIINFLAMATORNIH FARMACEUTIKA FOTOKATALITIČKOM DEGRADACIJOM PRIMENOM TITANIJUM-DIOKSIDA

The increased use of nonsteroidal antiinflammatory drugs like ibuprofen, diclofenac and ketoprofen lead to their presence in landfill leachate due to their inadequate disposal treatment. In this experiment during 90 minutes solutions of ibuprofen, diclofenac and ketoprofen with titanium dioxide are treated with UV light, and after that concentrations of remain drugs were detected using HPLC. The aim of the paper is to determine the possibility of photocatalytic degradation of ibuprofen, ketoprofen and diclofenac with titanium dioxide.
Structure and in situ organisation of the Pyrococcus furiosus archaellum machinery

The archaellum is the macromolecular machinery that Archaea use for propulsion or surface adhesion, enabling them to proliferate and invade new territories. The molecular composition of the archaellum and of the motor that drives it appears to be entirely distinct from that of the functionally equivalent bacterial flagellum and flagellar motor. Yet, the structure of the archaellum machinery is scarcely known. Using combined modes of electron cryo-microscopy (cryoEM), we have solved the structure of the Pyrococcus furiosus archaellum filament at 4.2 Å resolution and visualise the architecture and organisation of its motor complex in situ. This allows us to build a structural model combining the archaellum and its motor complex, paving the way to a molecular understanding of archaeal swimming motion.

Equivalently tilted Bragg waveguide grating and its applications to photonic devices

Tilted Bragg grating (TBG) has been intensively investigated for photonic devices such as fiber sensors and on-chip filters. In this paper, we present that TBG can be equivalently realized by designing tilted sampled Bragg grating (TSBG), which is formed by superimposing the pre-designed tilted sampling structure on the basic grating. Since the basic grating is uniform and the sampling structure is in the order of micrometer, the fabrication of TSBG can be realized with one step of holographic exposure combined with another step of micro-lithography. We designed and simulated the equivalent light responses of the TSBGs as that of the target TBG in the photonic devices. As examples, a mode converter based on TSBG has been proposed, which can be used for add-drop filter in the wavelength division multiplexing (WDM) technology combined with mode division multiplexing (MDM) technology. We also investigate the core-to-cladding mode coupling of TSBG in single-mode fiber for fiber sensing as well as the spatial filter in the α- DFB laser. The proposed technique may pave a new way for different 2D gratings with good design flexibility and easy fabrication in various photonic devices.
Congenital Heart Disease Gene Identification by Whole Exome Sequencing

Congenital Heart Disease (CHD) is the most common congenital defect, but the genetic aetiology of a large proportion of CHD is unexplained. This project aimed to delineate novel genetic causes of CHD using Whole Exome Sequencing (WES) in a family-based approach. Sixteen families were recruited to the study. WES data analysis followed a standardized pipeline and candidate variants were prioritized on the basis of in silico pathogenicity prediction tools and review of the current literature. Known and candidate genes in CHD were successfully identified using WES. In one family, a mutation in PIGV was identified, providing a diagnosis of Hyperphosphatasia and Mental Retardation syndrome and expanding the known phenotype of this condition. In a family with early-onset cardiomyopathy, a mutation in PPA2 was identified, encoding a mitochondria-specific pyrophosphatase enzyme. Through collaboration this gene was identified to be causative in three further families and mutation pathogenicity was investigated by functional studies. In a further family, a missense mutation in DNAAF1 was associated with heterotaxy, in the absence of clinical features of Primary Ciliary Dyskinesia, the phenotype usually associated with this gene. Zebrafish studies supported the pathogenicity of this variant and functional experiments identified novel interactants of DNAAF1 to include Pontin, Reptin and IFT88. Pontin was found to be expressed on the left side of the embryonic node in mice and zebrafish, a pattern which was abolished in dnaaf1-/- mutant fish, suggesting DNAAF1 and Pontin to be involved in the development of early laterality. In two families with athelia, choanal atresia and CHD a candidate variant in KMT2D was identified. The phenotype was distinct from Kabuki syndrome and is likely to represent a novel KMT2D-related disorder. WES was a successful tool in gene identification in CHD and, coupled with functional studies, has provided novel insights into the pathogenesis of CHD.
Organosolv lignin properties and their effects on enzymatic hydrolysis

Lignin plays a crucial role in enzymatic hydrolysis of lignocellulosic biomass. To evaluate the correlation between lignin properties and its effects on enzymatic hydrolysis, five organosolv lignins (OLs) were isolated from woody biomass, and their physico-chemical properties and structural features were characterized. The effects of OL addition on enzymatic hydrolysis of microcrystalline cellulose (pure cellulose) were assessed first, which showed their disparate effects. The addition of three OLs increased the 72 h hydrolysis yield by 7.4% to 10.1%, while the addition of other two OLs reduced the 72 h hydrolysis yield by 3.2% to 20.4%. A strong correlation between the enzyme distribution coefficient on lignins and the 72 h hydrolysis yields indicated that the enzyme-lignin interaction played a significant role in determining the lignin effects. More importantly, a correlation between lignin properties (hydrophobicity, zeta potential, and particle size) and the enzyme distribution coefficient was established. Identifying the key lignin properties will give insights to reduce the lignin inhibition by altering the lignin properties, thereby promoting enzymatic hydrolysis of lignocellulose.
The Status of the Ganges River Dolphin Platanista gangetica gangetica in the River Barak, Assam, India

The Ganges River Dolphin Platanista gangetica gangetica , once common in the River Barak in southern Assam, is now rarely sighted. Currently, the dolphins in winter (December-February) congregate in a 14 km stretch of the Barak centring on two sites. During the rainy season (mainly June-August), they frequent tributaries and flooded paddy fields. The population in the 135 km stretch of the Barak, before its bifurcation near the Indo-Bangladesh border, was estimated at 14, 12, 10, 9, 9, 8, and 8 in 1999, 2001, 2003, 2005, 2006, 2007, and 2008, respectively. About 60%, 31%, and 9% of the population was made up of adults, subadults and calves respectively. Information on 29 dolphin mortalities in the Barak comprised 28% adults, 34% subadults and 38% calves. Fishing activities were responsible for 90% of the mortalities; 37% of deaths of calves were due to entanglement in gill-nets. Direct and indirect hunting, uses of dolphin oil as fish attractant and medicine, habitat loss and degradation, depletion of prey fish, water development projects, lack of people's awareness, and poor law enforcement threaten the dolphins. Among others, notification of Barak Dolphin Sanctuary and strict enforcement of laws are required to conserve the dolphins in the Barak.
Downstream migration and mechanisms of dispersal of young fish in rivers1

Downstream migration (DSM) of young fish has traditionally been considered a passive process. A review of studies of the patterns and mechanisms of DSM showed that it met the main criterion for migration: that animals move between well-defined habitats according to a predictable schedule. During DSM, fish often leave the habitat in which they reside (inshore zone) and enter a migratory habitat (main channel). DSM is manifested at a seasonal or diel scale and in species-specific spatial distribution patterns. According to our “dispersal with low dilution” hypothesis, the supposed adaptive value of DSM is due not only to dispersal but also to maintenance of aggregations and synchronization of migratory activity. Temporal and spatial peaks of migration promote efficient intraspecific interactions, such as shoaling, and the integrity of populations. We conclude that migratory behaviour is most successful in habitats with optimum complexity and that the influence of behaviour on DSM is most important at key pe.
A narrow window of summer temperatures associated with shrub growth in Arctic Alaska

Warming in recent decades has triggered shrub expansion in Arctic and alpine tundra, which is transforming these temperature-limited ecosystems and altering carbon and nutrient cycles, fire regimes, permafrost stability, land-surface climate-feedbacks, and wildlife habitat. Where and when Arctic shrub expansion happens in the future will depend in part on how different shrub communities respond to warming air temperatures. Here, we analyze a shrub ring-width network of 18 sites consisting of Salix spp. and Alnus viridis growing across the North Slope of Alaska (68–71°N; 164–149°W) to assess shrub temperature sensitivity and compare radial growth patterns with satellite NDVI (normalized difference vegetation index) data since 1982. Regardless of site conditions and taxa, all shrubs shared a common year-to-year growth variability and had a positive response to daily maximum air temperatures (Tmax) from ca. May 31 (i.e. Tmax ∼6 °C) to early July (i.e. Tmax ∼12 °C), two-thirds of which were significant correlations. Thus, the month of June had the highest shrub growth-temperature sensitivity. This period coincides with the seasonal increase in temperature and phenological green up on the North Slope indicated by both field observations and the seasonal cycle of NDVI (a proxy of photosynthetic activity). Nearly all of the sampled shrubs (98%) initiated their growth after 1960, with 74% initiated since 1980. This post-1980 shrub-recruitment pulse coincided with ∼2 °C warmer June temperatures compared to prior periods, as well as with positive trends in shrub basal area increments and peak summer NDVI. Significant correlations between shrub growth and peak summer NDVI indicate these radial growth patterns in shrubs reflect tundra productivity at a broader scale and that tundra vegetation on the North Slope of Alaska underwent a greening trend between 1980 and 2012.
Phenotypic and Molecular Characterization of Vibrio harveyi in Diseased Shrimp

The objective of this study was to characterize Vibrio harveyi phenotypically and by molecular methods. A total number of 420 shrimp post larvae samples were collected, 280 samples of diseased cultured shrimp and 140 samples of apparently healthy marine shrimp. The samples were subjected to bacteriological examination. Thirty three (11.7%) of cultured shrimp samples and 4 (2.8%) of marine shrimp samples were phenotypically positive for V. harveyi. Species - specific gene (toxRgene) and two virulence associated genes (vhh -Vibrio harveyi haemolysin, and partial hly- haemolysin gene) were investigated using conventional PCR. This study proved that using of partial haemolysin gene in molecular characterization of V. harveyi is the fastest and most accurate method to identify all isolates of V. harveyi (highly pathogenic, moderately pathogenic and non-pathogenic strains) due to the presence of a single copy of haemolysin gene encoded in all isolates, although it is not in the same locus in the genome.
