Ultrasensitive and highly specific detection of iodine ions using zirconium (IV)-enhanced oxidation
2022
Nuclear energy has significantly promoted the development of human society. However, nuclear pollution caused by nuclear accidents can lead to significant hazards to the environment and human health. As a major radioactive product, radioactive iodine (mainly existing as I−) detection has attracted significant attentions. In this study, zirconium(IV) is used to enhance the oxidation of environmental I− to form I2. Subsequently, the generated I2 oxidizes the chemical chromogenic substrate 3,3′,5,5′-tetramethylbenzidine, which is used for I− detection and realizes an ultralow limit of detection (LoD) of 0.176 nM. The LoD of our method, to the best of our knowledge, is the lowest among those of…
Salivary Microbiota Composition in Patients with Oral Squamous Cell Carcinoma: A Systematic Review.
2022
Background: Oral squamous cell carcinoma (OSCC) is one of the most prevalent cancers worldwide. Despite recent advances in diagnosis and treatment, in recent years, an increase in the incidence of OSCC has been registered, and the mortality rate is still high. This systematic review aims to identify a potential association between the composition of salivary microbiota and OSCC. Materials and Methods: The protocol for this study was designed following the PRISMA guidelines. Records were identified using different search engines (e.g., Medline/PubMed). Observational studies, in human subjects with histological diagnosis of OSCC, concerning the analysis of salivary microbiota, were selected. …
Theoretical advancements on a recently proposed method to measure rainfall energy
2022
Soil erosion induced by rainfall is mainly due to the rainfall impact besides the consequent surface runoff. Rainfall kinetic energy is the most used variable to represent its erosivity. The latter represents the weathering attitude to erode soil and is a fundamental variable of the erosion process. Consequently, precise measurements of rainfall erosivity have to perform to develop a reliable prediction model of the erosive phenomenon. Currently, impact energy can be reliably measured only by disdrometers. These instruments measure the Drop Size Distribution (DSD) which, joined with the raindrop falling velocity, allow to calculate, by integration, the impact kinetic energy. However, disdro…
3-Methylation alters excited state decay in photoionised uracil.
2022
UV and VUV-induced processes in DNA/RNA nucleobases are central to understand photo-damaging and photo-protecting mechanisms in our genetic material. Here we model the events following photoionisation and electronic excitation in uracil, methylated in the 1′ and 3′ positions, using the correlated XMS-CASPT2 method. We compare our results against those for uracil and 5-methyl-uracil (thymine) previously published. We find 3-methylation, an epigenetic modification in non-negligible amounts, shows the largest differences in photoionised decay of all three derivatives studied compared to uracil itself. At the S0 minimum, 3-methyl-uracil (3mUra) shows almost degenerate excited cation states. Upo…

Young Consumers’ Boycotting Profiles in the UK and Finland : A Comparative Analysis
2022
This study uses latent profile analysis to identify boycotting subgroups within Finland and the UK and to explore their potential differences across countries. These subgroups are based on how young British and Finnish consumers assess that reference groups and their personal experiences have influenced their boycotting decisions. This study is based on comparative data obtained from the UK (n = 1,236) and Finland (n = 1,219). We identified four boycotting profiles: unlikely to be influenced, influenced by personal things, likely to be influenced, and moderately likely to be influenced. Our findings are especially relevant to consumer researchers, brands, and companies. peerReviewed
Unprotected sex among female Italian uni- versity students: A «Calculated Risk»
2022
Contraception is considered a rational strategy to prevent unwanted births. However, beyond the dichotomy of «planned» and «unplanned» pregnancy, behaviours are sometimes ambivalent or contradictory. The present paper inves tigates the reasons beyond the non-use of contraception in Italy by examining a large-scale survey of university students conducted in 2000 and 2017. The findings reveal a small but clearly defined group of young female students, cohabiting with their partner and residing in the South of the country, who have a high frequency of sexual intercourses and do not deliberately use any contra ceptive method. These findings offer population-based evidence about the ex istence o…
A multifaceted field sampling approach for the management of extremely narrow endemic vascular plant species
2022
Extremely narrow endemic plant species (ENEs) are generally connected with micro- refugia characterized by particular environmental conditions. In-depth knowledge of the ecological requirements of ENEs is fundamental to plan appropriate conservation measures. Using cross-cutting technology, this paper gives a multifaceted approach to collect on-site data on the ecology of ENEs, defines the protocols for a correct sampling design and describes the type of equipment, the time and expenditure needed. Our sampling approach is based on two orthogonal transects, long enough to extrapolate the whole ecological gradient across the area of occupancy of the target species. Microclimatic data are reco…
Teacher–student relationship and students’ social competence in relation to the quality of educational dialogue
2022
Teacher–student relationship and students’ social competence were investigated in relation to the quality of educational dialogue. The data consisted of 151 video-recorded Grade 2 lessons. The teachers (N = 50) also rated their students’ (N = 664) social competence and the teacher–student relationship. In terms of teacher–student relationships, closeness associated positively while conflict associated negatively with high quality dialogue. Regarding students’ social competence, cooperation skills and empathy linked positively while disruptiveness linked negatively with high quality dialogue. The findings provide new knowledge on how different student-related factors may support or prevent t…
Colorectal infiltrating deep endometriosis: Laparoscopic treatment. A case report
2022
Endometriosis is a disease affecting approximately 10% of women of fertile age. A particular presentation is deep infiltrating endometriosis of the rectosigmoid colon with symptoms that can mimic an intestinal obstruction or neoplasm. We report the case of a 39-year-old woman with pelvic pain during the menstrual cycle and significant anemia who presented an ectopic endometrial tissue in correspondence of the rectum. Because of the thickness of the lesion the patient underwent a segmental laparoscopic colorectal resection with end-to-end anastomosis.
Characteristics and Subjective Evaluation of an Intelligent Empowering Agent for Health Person Empowerment
2022
Empowerment is a process through which people acquire the necessary knowledge and self-awareness to understand their health conditions and treatment options, self-manage them, and make informed choices. Currently, few stand-alone applications for patient empowerment exist and people/patients often go on the Web to search for health information. Such information is mainly obtained through generic search engines and it is often overwhelming, too generic, and of poor quality. Intelligent Empowering Agents (IEA) can filter such information and assist the user in the understanding of health information about specific complaints or health in general. We have designed and developed a first prototy…

Factor Structure and Measurement Invariance of the Spanish Burnout Inventory Among Professionals Across 17 Countries and Regions
2022
AbstractStudies on the prevalence of burnout in professionals in service organizations who work in direct contact with the clients or users of the organization have concluded that burnout is a serious health disorder that has increased due to the COVID-19 pandemic. A significant advantage of the Spanish Burnout Inventory (SBI) over other instruments is that it provides a broader conceptualization of burnout by including feelings of guilt as a dimension of burnout to explain its development. However, the measurement invariance of the SBI across countries has not been investigated. The purpose of this study was to test the measurement invariance of the SBI among professionals across 17 countr…

Nanostructured Lead Electrodes with Reduced Graphene Oxide for High-Performance Lead–Acid Batteries
2022
Nanostructured Pb electrodes consisting of nanowire arrays were obtained by electrodeposition, to be used as negative electrodes for lead–acid batteries. Reduced graphene oxide was added to improve their performances. This was achieved via the electrochemical reduction of graphene oxide directly on the surface of nanowire arrays. The electrodes with and without reduced graphene oxide were tested in a 5 M sulfuric acid solution using a commercial pasted positive plate and an absorbed glass mat separator in a zero-gap configuration. The electrodes were tested in deep cycling conditions with a very low cut-off potential. Charge–discharge tests were performed at 5C. The electrode wi…

Diagnostic delay of oral squamous cell carcinoma and the fear of diagnosis: A scoping review.
2022
The mortality rate of patients affected with oral squamous cell carcinoma (OSCC) has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient’s fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnosti…
The invasion history of Elodea canadensis and E. nuttallii (Hydrocharitaceae) in Italy from herbarium accessions, field records and historical litera…
2022
AbstractWe analysed the invasion history of two North American macrophytes (Elodea canadensis and E. nuttallii) in Italy, through an accurate census of all available herbarium and field records, dating between 1850 and 2019, and a rich literature collection describing the initial introduction and naturalisation phase that supports the results obtained by the occurrence records. Elodea canadensis arrived in Italy before 1866 and had two invasion phases, between the 1890s and 1920s and between the 1990s and 2000s; E. nuttallii, probably arrived in the 1970s, started invading in 2000 and the invasion is still ongoing. Botanical gardens and fish farming played a crucial role in dispersal and na…
Theoretical prediction of rainfall intensity for a small rainfall simulator
2022
In this contribution, a theoretical approach was developed for predicting rainfall intensity for a small rainfall simulator. The developed equation was tested for two different devices and different pressure head and water temperature values. The proposed relationship was found to have a good predictive ability of rainfall intensity. The proposed theoretical approach could be usable with other devices that operate on the same principles of the simulator considered in this investigation.
An analysis of botanical studies of vascular plants from Italian wetlands
2022
Wetlands are essential for life on Earth, but at the same time the most threatened environments due to the gradual alterations associated with climate change and human action. The botanical studies on wetland higher plants carried out in Italy from 1950 until today are analysed in this survey. The 1,265 contributions resulting from this study are analysed from a historical, geographical, and content point of view. Most of the scientific contributions were published in the 1980s and 1990s, often by the same research groups and on a local scale. The predominant research theme is the inventory. Most papers are mainly focused on lakes and rivers. The results of this literature survey point to t…
Measuring the USLE soil erodibility factor in the unit plots of Sparacia (southern Italy) experimental area
2022
The Universal Soil Loss Equation (USLE) is still widely used to predict soil loss by water erosion and to establish soil conservation measures. In this model, the soil erodibility factor K accounts for the susceptibility of the soil to be eroded due to the detachment and transport processes operated by the erosive agents. According to the USLE scheme, the K factor should be measured on unit plots, i.e., bare plots of given length (22 m) and steepness (9%) tilled along the maximum slope direction, but there is little evidence that there ever existed an actual unit plot between the plots used to develop the USLE. Given the difficulty in collecting sufficient data to adequately measure K, the …
Sense of country: General and specific factors covary with social identification and predict emigration plans
2022
Theoretical analyses of person–environment interaction describe complex models, addressing different levels of social systems, while models of the sense of community provide a base for transferring views of this interaction to the national level. This paper presents two studies that explored the structure of the sense of country and its relation to emigration plans and social identification. Study 1 involved 1,005 adults from Latvia. The Sense of Country Inventory (SOCI) included influence, perceived opportunities, belonging, and spatiotemporal commitment as the components of this sense. The bifactor model demonstrated the best fit and confirmed the general factor, integrating components of…

Systemic circulating microRNA landscape in Lynch syndrome
2022
AbstractMicroRNAs (miRs) are non-coding RNA-molecules that regulate gene expression. Global circulating miR (c-miR) expression patterns (c-miRnome) change with carcinogenesis in various sporadic cancers. Therefore, aberrantly expressed c-miRs could have diagnostic, predictive and prognostic potential in molecular profiling of cancers. c-miR functions in carriers of inherited pathogenic mismatch-repair gene variants (path_MMR), also known as Lynch syndrome (LS), have remained understudied. LS cohort provides an ideal population for biomarker mining due to increased lifelong cancer risk and excessive cancer occurrence. Using high-throughput sequencing and bioinformatic approaches, we conducte…
Tutkijakollegiumit, tieteidenvälisyys ja huippututkimuksen ideaali
2022
Suomesta ei löytyne yliopistoa, joka ei strategiassaan nimeäisi tieteidenvälisyyttä yhdeksi keskeiseksi keinoksi tavoitella huippututkimusta (research excellence). Tässä tutkimuksessa kysymme, millaisia käsityksiä tutkijakollegiumien johtajilla on tieteidenvälisyyden roolista huippututkimuksen tavoittelussa. Lisäksi tutkimme, miten tieteidenvälisyydelle luodaan tilaa ja mahdollisuuksia tutkijakollegiumien arjessa.

Identity and Value of Public Space: Multifaceted and Multicultural Points of View
2022
Il tema dello spazio pubblico, della sua definizione e descrizione e della sua trasformazione è certamente estremamente attuale e rilevante. Se l'approccio identitario aiuta a comprendere l'essenza di un luogo, oggi è necessario essere consapevoli che l'identità è qualcosa che può cambiare nel tempo. Basta dare un'occhiata all'Agenda 2030 per lo sviluppo sostenibile, adottata da tutti gli Stati membri delle Nazioni Unite nel 2015, per capire che l'Agenda si concentra su questi temi. Le considerazioni presentate in questo articolo, partendo da una riflessione sullo spazio pubblico, ragionano sui temi dell'identità e del valore. L'argomentazione si basa sulle nuove forme di spazio pubblico e …
13C and 15N NMR Detection of Metabolites via Relayed Hyperpolarization at 1 T and 1.4 T
2022
Nuclear-spin hyperpolarization allows various magnetic-resonance applications in chemistry and medicine that are unattainable by standard methods. For such applications, parahydrogen-based hyperpolarization approaches are particularly attractive because of their technical simplicity, low cost, and ability to quickly (in seconds) produce large volumes of hyperpolarized material. Although many parahydrogen-based techniques have emerged, some of them remain unexplored due to the lack of careful optimization studies. In this work, we investigate and optimize a novel parahydrogen-induced polarization (PHIP) technique that relies on proton exchange referred to below as PHIP-relay. An INEPT (insen…
Human capital and the intertemporal substitution for leisure: empirical evidence for Spain
2022
AbstractIn this paper we provide the first estimate of the intertemporal substitution for leisure in Spain, accounting for the impact of human capital accumulation. This would allow uncovering whether the intertemporal labour supply of Spanish workers is affected by human capital. Our empirical strategy consists of estimating the equation for the intertemporal substitution of leisure with and without accounting for human capital, what allows to detect hypothetical estimation biases associated to omitting the impact of human capital. To that end, we build a pseudo-panel data set combining the Spanish Family Expenditure Survey and the Labour Survey over the period 1987–1997. While the model t…
Emergence and early institutionalization of competition in higher education: evidence from Finnish business schools
2022
AbstractThis paper investigates the emergence and early institutionalization of competition in higher education (HE), specifically in business schools. First, building on key contributions from economics, management studies, sociology, and HE research, we develop propositions on competition in HE and formulate our theoretical framework. Second, we apply this framework to explore competition in Finnish business schools. We argue that business schools constitute an interesting field for studying competition in HE because they are the frontrunners and champions of competition-based views in HE. Our main contribution is a novel explanation of the preconditions, emergence, and early processes of…
In the Name of Antigone: Migrants and Human Rights in Contemporary Urban Spaces
2022
Starting from the metaphor of the ethical conflict between dignity and rights in Antigone, the article reflects on the theme of human dignity for a critique of global inequalities. These theoretical assumptions are the basis for reflecting on the theme of contemporary international mobility of populations, which generates significant effects on the production of borders and the right to the city, highlighting new issues of social and spatial justice. In particular, with respect to the “newcomers”, claiming the “right to the city”, after claiming the “right to mobility”, very often coincides with the claim and protection of human rights, in order to build “spaces for survival”. On the one ha…
Entangled Assemblages: The Mutual Becoming of Food and More-than-Human Being
2022
AbstractFood and life are intimately entangled. To grasp the underlying complexity of this seemingly simple statement, this article first introduces the approach to food/eating as an assemblage enacted by various heterogeneous components, and further develops it by engaging with actor network theory and material semiotics. Thereafter the focus turns to ‘entanglement’, as inspired by quantum physics, to elicit the basic dynamics of the entanglement of food and more-than-human beings, conceived of as involving mutual and differential becomings within and among assemblages. The article illustrates these entangled becomings by drawing upon examples from Sri Lanka, which in an intercultural phil…
Assessing incentives to increase digital payment acceptance and usage: A machine learning approach.
2022
An important step to achieve greater financial inclusion is to increase the acceptance and usage of digital payments. Although consumer adoption of digital payments has improved dramatically globally, the acceptance and usage of digital payments for micro, small, and medium-sized retailers (MSMRs) remain challenging. Using random forest estimation, we identify 14 key predictors out of 190 variables with the largest predictive power for MSMR adoption and usage of digital payments. Using conditional inference trees, we study the importance of sequencing and interactions of various factors such as public policy initiatives, technological advancements, and private sector incentives. We find tha…
