Hydrogen Bonding in Amorphous Alkaline Earth Carbonates
2018
Amorphous intermediates play a crucial role during the crystallization of alkaline earth carbonates. We synthesized amorphous carbonates of magnesium, calcium, strontium, and barium from methanolic solution. The local environment of water and the strength of hydrogen bonding in these hydrated modifications were probed with Fourier transform IR spectroscopy,
How Do QR Codes Enhance Customer Experience? : Omnichannel Customer Experiences in a Brick-and-Mortar Fashion Store
2023
In this qualitative study, we investigate how customers perceive QR codes enhancing their customer experience (CX) in the brick-and-mortar (B&M) store environment. Introducing QR codes to B&M stores is a part of the larger phenomenon of retailers creating omnichannel CXs by utilizing digital and cyber-physical elements in B&M stores. To collect data from real customers’ CXs, we displayed QR codes in a Finnish fashion brand’s B&M store and interviewed customers who had authentically visited the store. The QR codes displayed in the store were linked to a product information page on the brand’s online store, a brand ambassador’s Instagram posts, and an online survey. The data consist of 15 ind…
Customers’ QR Code Usage Barriers in a Brick-and-Mortar Store : A Qualitative Study
2023
The purpose of this study is to explore the factors that hinder customers from utilizing QR codes when they visit brick-and-mortar (B&M) stores. The research was conducted at a Finnish fashion retailer, where three types of QR codes were displayed for customers to use. In order to identify the barriers that customers face, two different sets of data were collected and analyzed: open-ended survey data (n = 101) and interview data (n = 16). The findings showed two main categories of barriers,customer and company related, with seven sub-barriers. The customer-related barriers included lack of interest in QR codes, user-related usage issues, desire for a device-free B&M store, and dislike towar…
Who are the Showroomers? Socio-Demographic Factors Behind the Showrooming Behavior on Mobile Devices
2022
This quantitative study focuses on socio-demographic variables and their associations with different forms of showrooming behavior. The purpose of this study is to find which consumer groups based on age, gender, and income level are demographically the most probable showroomers, and how much each of these variables explain showrooming. The data used is a structured online survey from 1,028 Finnish omnichannel consumers aged between 18 and 75 years. We compare the means of demographic groups’ shares on different aspects of showrooming, and then use partial least squares structural equation modeling with confirmatory factor analysis to see how much each of the variables explain showrooming. …
The Cross-Channel Effects of In-Store Customer Experience in the Case of Omnichannel Fashion Retailing in Finland
2023
Although omnichannel retailing has emerged as a popular research topic in academic research, there are still gaps in our understanding of this phenomenon. One such gap concerns omnichannel customer experience and particularly the cross-channel or spillover effects of how customer experience in one channel may affect customer behaviour not only in that specific channel but also in the other channels of the same retailer. In this study, we aim to address this gap by examining how customer experience in the offline channel affects customer behaviour in both the offline and the online channel, more specifically how in-store customer experience affects both brick-and-mortar store and online stor…
The importance of online retailers' ethics for traditional, online and multichannel customers
2021
This chapter explores the role of retailers’ ethics in consumer behaviour and channel selection. It is largely acknowledged that many ethical issues in online retailing differ from those of traditional brick-and-mortar retailing. However, there is limited understanding of how ethical considerations vary among consumers that use various shopping channels. Our analysis is based on survey data from traditional shoppers (n = 216), online shoppers (n = 224) and multichannel shoppers (n = 244) in Finland. We firstly examine how these three customer types perceive four key elements of online retailer ethics: security, privacy, non-deception and fulfilment. Secondly, we examine how consumers’ perce…
Fabrication and characterization of nanostructured Ni and Pd electrodes for hydrogen evolution reaction (HER) in water-alkaline electrolyzer
2017
In the field of water-alkaline electrolyzer, the development of nanoporous low cost nickel electrodes is one of the potential approaches to increase electrocatalytic activity. Template electrodeposition is a facile and cheap technique for obtaining Ni nanowires (NWs) with high surface area. These nanostructures were fabricated by a two-step procedure. In the first step, a Ni compact layer was deposited on one side of the template where a gold film was previously sputtered, while, in the second-step, an ordered array of Ni-NWs was obtained by electrodeposition inside the template channels. The NWs were firmly connected to the underlying Ni layer, acting as a current collector. In order to en…
Zein as biodegradable material for effective delivery of alkaline phosphatase and substrates in biokits and biosensors
2016
A biodegradable material, zein, is proposed as a reagent delivery platform for biokits and biosensors based on alkaline phosphatase (ALP) activity/inhibition in the presence of phosphatase substrates. The immobilization and release of both the substrate and/or the active ALP, in a biodegradable and low-cost material such as zein, a prolamin from maize, and in combination with glycerol as plasticizer have been investigated. Three zein-based devices are proposed for several applications: (1) inorganic phosphorus estimation in water of different sources (river, lake, coastal water and tap water) with a detection limit of 0.2mg/L - compared to at least 1mg/L required by legislation, (2) estimat…
Metástasis óseas secundarias a carcinoma renal diagnosticadas mediante gammagrafía ósea
2001
We reported the case of a 35-y-old man with renal cell carcinoma and cold lesions detected by bone scintigraphy, related to metastatic involvement. Conventional X-Ray did not show any pathological findings, being confirmed by axial computed tomography (CT) the scintigraphic bone lesions. We have accomplished a discussion of the role of bone scintigraphy and complementary techniques (radiography, alkaline phosphatase levels) in the diagnosis of bone metastases in renal cell carcinoma.
Serum alkaline phosphatase is elevated and inversely correlated with cognitive functions in subjective cognitive decline: results from the ReGAl 2.0 …
2020
Background: Alkaline phosphatase has been found on neuronal membranes and plasma alkaline phosphatase (ALP) activity increases during brain injury and cerebrovascular diseases, suggesting that its levels may reflect the neuronal loss. It is known that ALP is higher in subjects affected by Alzheimer’s dementia and inversely correlated with cognitive functions. No study has investigated the relationship between ALP and cognitive functions in old-age subject with pre-clinical cognitive impairment. Methods: This is a cross-sectional study with data gathered from the ReGAl 2.0 project (Rete Geriatrica Alzheimer-Geriatric Network on Alzheimer’s disease), a large Italian multicentric clinical-base…
