Exploring travel blogs on tourism and landscape heritage: representations of the Swiss Alps

ABSTRACT Alpine tourism is one of the most popular forms of travel. Despite the prominence of information and communication technology in shaping travel perceptions and behaviour, a research gap has been identified concerning how this phenomenon is represented online. By taking the case of Alpine tourism in Switzerland, in this qualitative research we use a thematic content analysis to investigate themes and narratives about Alpine landscape and tourism in 158 blog posts. Findings show, first, that Alpine tourism representations can be grouped into six themes: Accessible Mountains, Captured Landscapes, Isolated Land, Healing Place, Cultural Discovery, and Natural Heritage. Second, representational narratives that can be ascribed to the Authorised Heritage Discourse appear to coexist with counter-narratives where the purely visual and aesthetic aspects of the Alps are combined with critical, experiential, and cultural elements. Research implications include the role of visual experiences in heritage representation and commodification, and the importance of integrating blogs in mountain tourism destination websites.
Importance of the macroeconomic variables for variance prediction : a GARCH-MIDAS approach

This paper applies the GARCH-MIDAS (Mixed Data Sampling) model to examine whether information contained in macroeconomic variables can help to predict short-term and long-term components of the return variance. A principal component analysis is used to incorporate the information contained in different variables. Our results show that including low-frequency macroeconomic information in the GARCH-MIDAS model improves the prediction ability of the model, particularly for the long-term variance component. Moreover, the GARCH-MIDAS model augmented with the first principal component outperforms all other specifications, indicating that the constructed principal component can be considered as a good proxy of the business cycle.
A Unified Formulation of Polarimetric Weather Radar With Application to IQ Data Simulation

The meteorological parameters derived from polarimetric weather radar measurements are of interest for nowcasting and to feed numerical models for forecasting. The accuracy of the derived meteorological parameters is affected by the polarimetric measurement scheme considered as well as by the system hardware (e.g., the antenna radiation patterns or receive channels imbalances). However, determining the accuracy of the estimated meteorological parameters is difficult since no ground truth is available. This fact has motivated the development of weather radar data simulators that allow comparison of the assumed weather parameters used to feed the system and the finally estimated weather parameters. In this paper, the weather radar model is reviewed. A unified formulation applicable to all polarimetric measurement systems is developed. This formulation shows that antenna effects can be decoupled from scattering effects. Based on this formulation, a weather radar simulator is proposed. This radar simulator does not require the fine sampling in the elevation and azimuth directions required by previous simulators. Therefore, the computational load and execution times are significantly reduced. Finally, it is important to point out that the radar simulator proposed provides as much fidelity to the actual radar system as previous simulators.

IgM memory and Waldenstr ö m macroglobulinemia's cell of origin

Waldenstr ö m macroglobulinemia (WM) is a neoplasm of mature IgM - expressing B - lymphocytes that is characterized by the occurrence of a monoclonal IgM (mIgM) paraprotein in blood serum and the infiltration of hematopoietic bone marrow with malignantly morphoplasmacytic cells. WM remains incurable despite the development of new therapeutic options. Owing in large measure to having alow incidence, indolent clinical course and good long - term control with proper clinical management, WM has not been investigated as extensively as other B - lineage neoplasms. Major knowledge gaps in our understanding of the natural history of WM include the cell of origin. With that short-coming in mind, here we discuss the significance of a specific gain - of - function mutation in the adapter protein: myeloid differentiation primary response 88 (MYD88), that occurs with near - complete penetrance in WM and suggests that tumor development is under strong selective pressure for elevated MYD88 signaling. This provides an intriguing link to IgM memory B - cells, which comprises of two types of B - lymphocytes （ natural effector IgM + IgD + cells and IgM - only IgM + IgD - cells ） that depend, in part, on MYD88 signaling and constitute intriguing candidates for WM's cell of origin.We review the features and developmental history of IgM memory in greater depth and propose that WM may be derived from primitive innate - like B - cells (marginal zone B - cells and B1 B - cells) that feed the IgM memory compartment. We conclude with a model of MYD88 - dependent tumor development in the mature B-cell lineagethat considers two different (convergent or divergent) oncogenesis pathways with respect to the cell of origin.

Performance of faecal contamination indicators in different type of waters from the sabana of Bogotá (Colombia)

The world’s population is growing at such rate that not only the demands for water supply have raised considerably but also its contamination levels. Residues from domestic and industrial origin have generated environmental problems and public health issues. Water contamination coming from domestic origin, shows a higher risk because of the quantity of organic matter and the presence of pathogenic microorganisms. Due to determinations of these pathogens requires sophisticated laboratories and the techniques used for their detection are very costly and time consuming, it is proposed an alternative technique using bacteria, virus and parasites as faecal indicators, since they exhibit similar behaviour, and their determination techniques are a lot simpler, faster and low cost. The objective of the present study is to evaluate the occurrence, concentration and behaviour of indicators from bacterial origin as faecal coliforms, from viral origin as somatic coliphages and F-specific RNA bacteriophages, and from parasite origin such as helminth eggs, Giardia cysts and Cryptosporidium oocysts. A series of samples were taken at surface, groundwater, drinking water and wastewater treatment system in the surrounding area of Bogota (Colombia). The results show the presence of all microbial indicators in all water samples, in similar concentrations to those found in different countries with different environments.
Extracting activist events from news articles using existing NLP tools and services

Activists have a significant role in shaping social views and opinions. To find out specifically how they are doing this, social scientists study the events activists are involved in. Unfortunately, individual sources may present incomplete, incorrect, or biased event descriptions. We present a method where we automatically extract event mentions from di↵erent news sources that could complement, contradict, or verify each other. The extraction will ultimately feed a visual analytics application that supports discovery and analysis in large amounts of event data. This document is the full thesis, also attached is a scientific paper that describes the essence of the thesis.
The Influence of Repeated Prescribed Burning and Forest Conversion on Soil Fungal Communities

Fungi are key components in forest ecosystems, being involved in decomposition of plant biomass and the cycling of nutrients in forest soils. Despite their importance little is understood about the influence forest management practices, such as long-term prescribed burning and forest conversion are having on soil fungal communities. Part of the work described in this thesis investigated the effects of long-term repeated prescribed burning on the total soil fungal community, the diversity of mycelial communities of ectomycorrhizal fungi and the influence of biennial prescribed burning on the cellulolytic soil fungal community using stable isotope probing techniques. The influence of long-term repeated prescribed burning on soil fungal communities was investigated through a series of studies conducted at Peachester State Forest, Queensland, Australia. This site has been the centre of a long-term repeated prescribed burning experiment, established since 1972, consisting of plots subjected to biennial, quadrennial or no burning.
Participants’ Bias in Disability Research on Family Quality of Life during the 0–6 Years Stage

Background: Over the past two decades, various research teams have designed and applied instruments to measure the quality of life of families with a member who has a disability. A recent systematic review on the state of the Family Quality of Life in early care identified that many of these studies collected data only from the mothers. The present study aimed to investigate whether there is a bias in participant selection in these types of studies. Method: A systematic review of the scientific literature was conducted in three databases—Scopus, Web of Science, Eric—from 2000 to 2022. A total of 72 empirical studies were identified. Results: The findings indicate that most studies examining the Family Quality of Life were based on the information of a single informant per family unit. The profiles of participants according to the research objective are quite similar. In one-third of studies, the authors reported that family members who participate cannot be represented by only mothers or one participant per household. Conclusions: Given the dynamic and collective nature of the construct, the application of a systemic approach is necessary.
Co‐axial electrospinning of liposomal propolis loaded gelatin‐zein fibers as a potential wound healing material

In this study, propolis extract (PE) was first encapsulated in different liposomal formulations (65–370 nm) with high encapsulation efficiency (68%–93%). The liposomal PE was further embedded in a food‐grade gelatin‐zein core/shell fiber by using the co‐axial electrospinning method. Transmission electron and confocal laser scanning microscopy verified the structure of liposomes and their homogeneous dispersion in fibers. Scanning electron microscopy (SEM) images confirmed the smooth morphologies of core/shell liposomal fibers. The loading of PE in liposomal fibers improved both thermal (differential scanning calorimetry) and textural (elongation at break and tensile strength) properties, and the fibers loaded with more PE provided higher mucoadhesiveness. The PE‐loaded fiber showed higher antimicrobial activity against Staphylococcus aureus. The incorporation of liposomal PE in fiber enhanced the viability of human skin fibroblast (HFF‐1) cells. The adhesion of HFF‐1 cells on fiber was demonstrated by SEM, thus PE‐loaded liposomal fiber could provide an efficient platform for cell growth. The findings of this study proposed that propolis‐loaded liposomal hybrid fibers produced by the co‐axial method can be used as a potential wound healing material.
ULTRASHORT LASER PULSE SHAPING AND CHARACTERIZATION FOR TAILORED ELECTRON BUNCH GENERATION ∗

Temporally-shaped laser pulse are desirable in various applications including emittance reduction and beam-driven acceleration. Pulse-shaping techniques enable flexible controls over the longitudinal distribution of electron bunches emitted from photocathode. While direct manipulation and measurement of ultrashort pulses can be challenging in the time domain, both actions can be performed in the frequency domain. In this paper, we report investigations toward the development of laser shaper and diagnostics at the Argonne Wakefield Accelerator. Simulations are presented to describe the shaping and measurement process based on a digital mask and a frequency resolved optical gating method
Does the merger improve the operating performance of the company? Evidence from the beverage industry in India

Background: There is fierce market competition both locally and globally. Every organisation seeks to maintain itself and, more crucially, to develop quickly through inorganic means. The expansion of a company through mergers and acquisitions is an inorganic process. Organic growth takes a very long period and is time-bound, but inorganic growth through mergers may be achieved quickly. This research aimed to determine whether the operating results of Indian beverage firms have improved after the merger or not. Methods: In order to assess merger-related advantages to the acquiring firms, this study used the operating performance technique, which contrasts the pre-merger and post-merger performance of corporations using accounting data. Secondary data were used to carry out this study. The operating performance was assessed on six operating parameters (ratios) i.e. Operating Profit Margin, Gross and Net Profit Margin, Debt-Equity, Return on Net Worth and Capital Employed. The comparison was done for three years pre and post-merger period of these operating ratios. Results: The findings demonstrate that mergers do not seek to increase owner wealth. This finding shows that rather than just becoming larger and achieving covert goals, managers should pay more attention to post-merger integration challenges in order to produce merger-induced synergies. Conclusion: This study shows that the M&As have not had a good effect on a company’s operating performance, especially for the chosen beverage companies in India. Since financial measures cannot fully account for the influence of mergers on business performance, future research may create other metrics for merger-related gains. Research that provides profound insights into the causes and trends of post-merger business performance through the different types of mergers and industries would also be beneficial.
Use of Cells, Supplements, and Peptides as Therapeutic Strategies for Modulating Inflammation after Spinal Cord Injury: An Update

Spinal cord injury is a traumatic lesion that causes a catastrophic condition in patients, resulting in neuronal deficit and loss of motor and sensory function. That loss is caused by secondary injury events following mechanical damage, which results in cell death. One of the most important events is inflammation, which activates molecules like proinflammatory cytokines (IL-1β, IFN-γ, and TNF-α) that provoke a toxic environment, inhibiting axonal growth and exacerbating CNS damage. As there is no effective treatment, one of the developed therapies is neuroprotection of the tissue to preserve healthy tissue. Among the strategies that have been developed are the use of cell therapy, the use of peptides, and molecules or supplements that have been shown to favor an anti-inflammatory environment that helps to preserve tissue and cells at the site of injury, thus favoring axonal growth and improved locomotor function. In this review, we will explain some of these strategies used in different animal models of spinal cord injury, their activity as modulators of the immune system, and the benefits they have shown.
Validity issues in the use of social network analysis with digital trace data

There is an exciting natural match between Social Network Analysis (SNA) and the growth of social interaction through digital platforms and technologies, from online communities to corporate information systems. This convergence offers a combination of exciting domains, interesting research questions, appropriate analysis techniques and the availability of copious data. Agarwal et al. (2008) put it thus, "Most transactions and conversations in these online groups leave a digital trace . this research data makes visible social processes that are much more difficult to study in conventional organizational settings. " The availability of such data, together with exciting domains and an appropriate analysis technique, form a golden opportunity for research, perhaps even a “21 Century Science” (Watts, 2007).
Application of Bioelectrical Impedance Analysis in Nutritional Management of Patients with Chronic Kidney Disease

Body composition measurement plays an important role in the nutritional diagnosis and treatment of diseases. In the past 30 years, the detection of body composition based on bioelectrical impedance analysis (BIA) has been widely used and explored in a variety of diseases. With the development of technology, bioelectrical impedance analysis has gradually developed from single-frequency BIA (SF-BIA) to multi-frequency BIA (multi-frequency BIA, MF-BIA) and over a range of frequencies (bioimpedance spectroscopy, BIS). As the clinical significance of nutrition management in chronic kidney disease has gradually become prominent, body composition measurement by BIA has been favored by nephrologists and nutritionists. In the past 20 years, there have been many studies on the application of BIA in patients with CKD. This review describes and summarizes the latest research results of BIA in nutritional management of patients with CKD including pre-dialysis, hemodialysis, peritoneal dialysis and kidney transplantation, in order to provide reference for the application and research of BIA in nutritional management of chronic kidney disease in the future.
Semantic Circle Detection and Circle-Inner Segmentation for Tree-Wise Citrus Summer Shoot Management in Aerial Images

This work focuses on a novel agricultural application of monitoring and managing summer shoots on citrus fruit trees. To enhance the management efficiency and reliability, a novel scheme based on aerial image analysis was presented to implement intelligent supervision. To this end, we proposed an end-to-end network containing three main modules, i.e. semantic circle detection, circle-inner segmentation, and decision classification. They are respectively in charge of detecting multiple trees, evaluating each tree’s shoot quantity, and predicting management decision for each tree in aerial images. Detailed experiment analysis validates the proposed scheme and network on the aerial images collected from practical citrus orchards.
Misinformation and Disinformation in Statistical Methodology for Social Sciences: causes, consequences, and remedies

This paper concerns the prevalence and the causes of low replication rates in Social Sciences. The aim is to frame unintentional errors as scientific misinformation, and questionable research practices as disinformation. In Section 3 is presented Multiverse Analysis, which helps the assessment of the uncertainty about scientific claims and reduces false discoveries. In order to introduce the topic of replication rate in Science, it is important to clarify the epistemological conditions to claim a scientific result to be replicated:
CHANNEL MIGRATION AND REGENERATION OF BALD CYPRESS IN WESTERN TENNESSEE

Bald cypress (Taxodium distichum) regeneration was examined in the bottomland forest of the lower Hatchie River in western Tennessee. Bald cypress is found mostly in abandoned meanders. Its absence along the active channel indicates that colonization begins after the meander cuts off, creating an oxbow lake. Analysis of the size, the age, and the spatial structure of the stands indicates that the individuals first establish along the margins of the lake, and then colonize the interior as the lake fills in and new surfaces are exposed. Bald cypress will dominate abandoned meanders for several centuries. However, it will not regenerate in stands with a well-developed forest canopy. Bald cypress is eventually replaced by shade tolerant species and, therefore, only rarely occurs on older surfaces. Channel migration and the subsequent creation of oxbows will maintain bald cypress as a major component of bottomland forests. However, many of the major streams in the lower Mississippi River alluvial valley have b.
Health risks of ozone from long-range transboundary air pollution.

Ozone is a highly oxidative compound formed in the lower atmosphere from gases (originating to a large extent from anthropogenic sources) by photochemistry driven by solar radiation. Owing to its highly reactive chemical properties, ozone is harmful to vegetation, materials and human health. In the troposphere, ozone is also an efficient greenhouse gas. This report summarizes the results of a multidisciplinary analysis aiming to assess the effects of ozone on health. The analysis indicates that ozone pollution affects the health of most of the populations of Europe, leading to a wide range of health problems. The effects include some 21 000 premature deaths annually in 25 European Union countries on and after days with high ozone levels. Current policies are insufficient to significantly reduce ozone levels in Europe and their impact in the next decade
