Long-term morphological modelling of tidal inlet systems: Implementing salt marshes in ASMITA
No full textA rise in the global mean temperature induced by climate change is expected to have a large impact on ecosystems in all regions of the world. One of the threats is accelerated sea level rise (SLR). This may induce the loss of intertidal areas in tidal inlet systems. The long-term morphological response of tidal inlet systems can be modelled using reduced complexity model ASMITA (Aggregated Scale Morphological Interaction between Tidal inlets and the Adjacent coast). The ASMITA model simulates morphological development on an aggregated spatial and temporal scale by imposing a morphological equilibrium condition. As such the model is fast, allowing for multiple long-term simulations. The model is physics-based and the parameters can be related to field values. Currently, salt marshes are not implemented in ASMITA. However, salt marshes could be of importance to the morphological development in tidal inlet systems. Moreover, it is relevant to assess the resilience of the ecologically important salt marshes by themselves. The aim of this research is to implement salt marshes in ASMITA to assess their influence on the rest of the tidal inlet system and to gain insight into the long-term morphological response of salt marshes to accelerated SLR. Salt marsh development is governed by horizontal and vertical processes. The marsh height increases by capturing mineral sediment and by the accumulation of plant biomass. Autocompaction and deep subsidence lead to a decrease in marsh height. The implementation of salt marshes in ASMITA relies solely on the input of mineral sediment. At the marsh edge, generally, a cyclic behaviour of sedimentation and cliff erosion occurs. Due to the high degree of spatial aggregation, cliff erosion is excluded from the model extension. The governing processes for salt marsh development in the ASMITA model extension are mineral sedimentation, sediment availability and relative SLR. The spatial and temporal aggregation of governing processes for salt marsh development are included in the aggregated advection-diffusion equation and model parameters for the horizontal & vertical exchange of sediment, and sediment availability. Data analysis on hydrodynamic conditions and salt marsh development was conducted for the derivation and calibration of these model parameters. To verify the salt marsh implementation, three ASMITA models were created. A one-element salt marsh model consisting of only a salt marsh element, and two different multiple elements models, which contain the ebb-tidal delta, channels, tidal flats and salt marshes. It can be concluded that ASMITA can model the mineral sedimentation on a salt marsh but depicts a large sensitivity to the parameter setting, particularly for the sediment concentration. Based on the chosen parameter configuration, the Oosterkwelder salt marsh is preserved when subjected to SLR rates below 16 mm/year. The ASMITA salt marsh extension can be employed to obtain an expeditious first impression of long-term morphological salt marsh development. However, due to the lack of incorporation of detailed processes, the model should not be employed for in-depth analyses of salt marsh development. The interaction between the salt marsh element and the remaining tidal inlet system components requires further model improvements.Civil Engineerin
#nowplaying-rs
No full text<p>The nowplaying-rs dataset features context- and content features of listening events. It contains 11.6 million music listening events of 139K users and 346K tracks collected from Twitter. The dataset comes with a rich set of item content features and user context features, as well as timestamps of the listening events. Moreover, some of the user context features imply the cultural origin of the users, and some others - like hashtags - give clues to the emotional state of a user underlying a listening event.</p>
<p>The dataset contains three files:</p>
<ul>
<li>user_track_hashtag_timestamp.csv contains basic information about each listening event. For each listening event, we provide an id, the user_id, track_id, hashtag, created_at </li>
<li>context_content_features.csv: contains all context and content features. For each listening event, we provide the id of the event, user_id, track_id, artist_id, content features regarding the track mentioned in the event (instrumentalness, liveness, speechiness, danceability, valence, loudness, tempo, acousticness, energy, mode, key) and context features regarding the listening event (coordinates (as geoJSON), place (as geoJSON), geo (as geoJSON), tweet_language, created_at, user_lang, time_zone, entities contained in the tweet).</li>
<li>sentiment_values.csv contains sentiment information for hashtags. It contains the hashtag itself and the sentiment values gathered via four different sentiment dictionaries: AFINN, Opinion Lexicon, Sentistrength Lexicon and vader. For each of these dictionaries we list the minimum, maximum, sum and average of all sentiments of the tokens of the hashtag (if available, else we list empty values). However, as most hashtags only consist of a single token, these values are equal in most cases. Please note that the lexica are rather diverse and therefore, are able to resolve very different terms against a score. Hence, the resulting csv is rather sparse. The file contains the following comma-separated values: <hashtag, vader_min, vader_max, vader_sum,vader_avg, afinn_min, afinn_max, afinn_sum, afinn_avg, ol_min, ol_max, ol_sum, ol_avg, ss_min, ss_max, ss_sum, ss_avg >, where we abbreviate all scores gathered over the Opinion Lexicon with the prefix 'ol'. Similarly, 'ss' stands for SentiStrength. </li>
</ul>
<p>Please note that user_track_hashtag_timestamp.csv and context_content_features.csv partly provide the same features. We deliberately chose to do so to be able to provide useable files that do not have to be matched and joined with each other to perform e.g., simple recommendation tasks.</p>
<p>Please also find the training and test-splits for the dataset in this repo. Also, Asmita provides prototypical implementations of a context-aware recommender system based on the dataset at https://github.com/asmitapoddar/nowplaying-RS-Music-Reco-FM.</p>

ASMITA modelling of the Wadden Sea with focus on the Groningerwad: Assessing how the Groningerwad will respond to accelerated sea level rise
No full textSome of the sediment which is eroded from the Dutch coast ends up in the Wadden Sea. Because of this the morphological development of the Wadden Sea is important, not only for the Wadden Sea itself but also for the maintenance programs of the adjacent coastlines. This is one of the reasons that the morphological development of the Wadden Sea is extensively studied. Some of these studies use the ASMITA model to make predictions of the morphological development with accelerating sea level rise. The Groningerwad is a part of the Wadden Sea consisting of a number of smaller tidal basins which has not been modelled with ASMITA. It has not yet been necessary to structurally nourish the coastlines surrounding the Groningerwad. However, as sea level rise increases it might well be possible that the coastal profiles surrounding the Groningerwad require nourishment. Therefore this thesis aims to study the Groningerwad with ASMITA to make a prediction of how the area will develop with accelerating sea level rise. To do this a morphological study is performed to determine the current morphological developments. This morphological study, based on available literature and bathymetry measurements of the area, finds that the Groningerwad is a highly dynamic area. It also determined the area and characterizing volume of each of the tidal basins, which have been used to set up the ASMITA model. For each basin in the Groningerwad an ASMITA model is set up using the information from the morphological study. The ASMITA model is used to make predictions for the development of the intertidal, channel and delta volumes of each of the Groningerwad its basins. The required parameters for the model have been derived from relevant formulas and the assumption that the Groningerwad is currently in a morphodynamic equilibrium. This was done because the time period for which bathymetrical measurements are available are to short to allow for a proper calibration procedure for these parameters. With this setup the ASMITA models show that all basins will lose intertidal sediment volume with rising sea levels. The larger basins of the Groningerwad also will not reach a new dynamic equilibrium state with large levels of sea level rise rate increase. When comparing these results to other basins in the Wadden Sea, it appears that the basins in the Groningerwad respond a lot slower than other Wadden Sea basins. Given the difference between the Groningerwad and the Wadden Sea and the fact that the time period over which bathymetrical data is available was to short to fully calibrate the model the recommendation is made to revisit this study when more data is available and it is possible to calibrate the relevant parameters.Civil Engineerin

Impact of Yoga on Cancer Patients
Full text linkThe aim of this study was to explore the impact of yoga on cancer patients through
existing literature. The purpose was to provide information that can be used by
nurses and to patient support well-being during cancer treatment.
The study was conducted as a literature review and the data was collected using
two databases: CINAHL and PubMed. Results from eight articles were analysed using
inductive content analysis method. The results revealed two main categories:
Psychosocial and Physiological & Biological Impacts and eight sub categories
namely; Quality of life, fatigue, stress & anxiety, depression, sleep quality, arm lymphoedema,
treatment related symptoms and overall toxicities and biological markers.
In conclusion, yoga positively influenced cancer patients’ quality of life, fatigue,
stress & anxiety, sleep quality, treatment related symptoms & overall toxicities and
biological markers. However, yoga may have wider scope of impact that needs to
be explored. Further research is recommended to study impact of yoga on other
cancer types and all eight limbs of yoga to verify it as an evidence-based option in
supportive treatment. Yoga could further be explored to find its influence on biological
markers of cancer. Lastly, yoga training could be provided as a nursing tool
to oncology nurses, thus they can encourage over all well-being of cancer patients
along with medical treatment
Building Sustainable Service concept for Buffet Lunch Restaurant in Nepal
Full text linkThe purpose of this thesis is to create a sustainable service concept for buffet lunch Restaurant in Nepal. XYZ Restaurant will imply local and seasonal food found in Nepal targeting Nepalese people of the different age groups in the Kathmandu Metropolitan area. XYZ restaurant will be formed based on the different research done in the Finnish lunch buffet market, with the intention of implementing good practices of Finnish restaurant in Nepal. The thesis consists of background topics of Nepalese food culture including basic elements, general, local and seasonal food of Nepal. This thesis also includes the customer behavior, their experience and eating habits. In addition, to introduce sustainability and accessibility in the restaurant, the background theory is supplemented dividing into two different topics of food waste, leftover, recycle management and customer with special needs. To support the theory background, the authors will use several sources which includes published literature, online books and articles.
The research methods used for the service development of this thesis are benchmarking through observation and online interviews. The first method, Benchmarking through observation was conducted with three different kinds of buffet restaurant in Helsinki metropolitan area who runs their business with the same concept, obtaining information about their service concept and strategy. The observation was done for one week during lunchtime with every individual restaurant. Various data were collected during the observation which includes menu type, pricing, total number of seats available, reservation service and the availability of infrastructure for people with special needs. A service blueprint was obtained by doing participant observation by one of the authors. To gain the customer eating habits and their choices for designing the menu and customer personas, an online interview was conducted through email by sending questionnaire related to the restaurant field. Interview participants are students, bartender, restaurant manager, study graduates and insurance company manager with residents in the Kathmandu metropolitan area and some Nepali living in Finland as well. Interview questionnaire efforts their restaurant and food type choice.
The outcome of this thesis is a sustainable service design concept for buffet lunch Restaurant in Kathmandu metropolitan area, created and developed by understanding the existing service culture of buffet restaurant in Helsinki metropolitan area as well as the customer experience and their habits from Nepal. Four cores activities of Service design methods are used to build this concept which includes Research, ideation, prototyping and implementation in which prototyping have been skipped by the authors. At a glance, the restaurant menu is inspired by the richness of Nepalese food culture and tradition along with the customer expectations using local food taste and paying attention towards better customer service and sustainability of the restaurant

Market orientation development in family owned small and medium enterprises
No full textThis research examined the nature of Market Orientation and analysed the extent of Market Orientation development in family owned small and medium sized enterprises. The causes and means that may be instrumental in developing a Market Orientation were also evaluated using a case study approach. A paucity of knowledge was identified in this area of researching Market Orientation in family owned SMEs especially with a qualitative methodology. The lack of research and need for balancing the importance of the disciplinary foundation of marketing with consideration to constraints of small business by adapting the implementation process of small business marketing was highlighted in the literature review. Accordingly a balanced approach was adopted of considering the Market Orientation concept as universal in principle whilst adapting it to the unique characteristics of family owned small and medium sized enterprises by emphasising some differences in the extent of Market Orientation and in the process of Market Orientation development. Accordingly the Researcher built an integrated conceptual framework using the SME stages model as a starting point and superimposing the effect of family ownership to focus on the process of Market Orientation adoption
