Moving from intention to behaviour: a randomised controlled trial protocol for an app-based physical activity intervention (i2be).
2022
IntroductionEfficacy tests of physical activity interventions indicate that many have limited or short-term efficacy, principally because they do not sufficiently build on theory-based processes that determine behaviour. The current study aims to address this limitation.Methods and analysisThe efficacy of the 8-week intervention will be tested using a three-condition randomised controlled trial delivered through an app, in women with a prior hypertensive pregnancy disorder. The intervention is based on the integrated behaviour change model, which outlines the motivational, volitional and automatic processes that lead to physical activity. The mechanisms by which the behaviour change techniq…
Impact of Nonlinear Inductor on Efficiency and Power Losses in a SMPS: a Case Study
2022
This paper proposes a comparative analysis focused on losses in two Switched Mode Power Supplies, adopting a linear inductor and an inductor operated up to saturation, respectively. The use of the nonlinear inductor saves weight and cost on the magnetic material, which is of great interest for automotive applications; however, it increases the peak current and can increase losses. The analysis aims to compare, by simulations, the impact on the efficiency of the different current waveforms throughout the converter. The losses are discussed in detail and calculated for each component of the converters.
La configuración formal de las palabras idiomáticas originadas por acortamiento en locuciones en español: los casos de amén, estampía, mor y ton
2022
En el presente artículo pretendemos analizar la configuración formal con la que han quedado fijadas cuatro palabras idiomáticas (amén, estampía, mor y ton) que se han formado mediante aféresis, síncopa y apócope, es decir, procesos de acortamiento o eliminación de un fragmento respecto a una base originaria. Nos centraremos en fenómenos habituales que presentan este tipo de voces así formadas, como la estructura silábica, la acentuación paroxítona o la dislocación acentual respecto a sus bases. Reservamos para estudios futuros un análisis fraseológico centrado en los sintagmas y funciones de las cinco locuciones que estas conforman.

Geotomus granulosus, a peculiar sehirine-like new species of the subfamily Cydninae (Hemiptera: Heteroptera: Cydnidae) from Burundi
2022
Geotomus granulosus sp. n. is described from Burundi, and is the third burrower bug species recorded hitherto from this country. This burrower bug resembles species of two Sehirinae genera, i.e. Ochetostethus Fieber, 1860 and Ochetostethomorpha Schumacher, 1913, in its dorsal body habitus. However, all its crucial diagnostic characters (the body chaetotaxy, the shape of evaporatoria and the peritreme, the meso- and metathoracic wings venation, and the shape of spermatheca) demonstrate it represents the genus Geotomus Mulsant et Rey, 1866 (subfamily Cydninae, tribe Geotomini sensu lato).
Worker safety in agriculture 4.0: A new approach for mapping operator's vibration risk through Machine Learning activity recognition
2022
While being a fundamental driver of competitiveness in agroindustry, technological innovation has also introduced new critical elements related, for example, to the sustainability of the production processes as well as to the safety of workers. In such regard, the advent of the 4th industrial revolution (Agriculture 4.0) based on digitalization, is an unprecedented opportunity of rethinking the role of innovation in a new human-centric perspective. In particular, the establishment of an interconnected work environment and the augmentation of the operator’s physical, sensorial, and cognitive capabilities, are two technologies which can be effectively employed for substantially improving the …
Enabling the Circular Economy Transition in Organizations: A Moderated Mediation Model
2022
The notion of Corporate Environmental Responsibility has been extensively researched in the literature so far, but less is known about how this concept fits into the circular economy paradigm. We performed a moderated mediation analysis in order to identify the mechanism that links corporate environmental responsibility with readiness for change towards a circular economy business model. The findings from 311 respondents show that there is a positive association between corporate environmental responsibility and the readiness for change to a circular model, mediated by perceived circular economy drivers. In addition, perceived circular economy barriers hinder this positive relationship, act…

Viral hepatitis in 2021: The challenges remaining and how we should tackle them
2022
Viral hepatitis results in 1.4 million deaths annually. The World Health Organization (WHO) set an ambitious target to eliminate viral hepatitis by 2030, but significant challenges remain. These include inequalities in access to healthcare, reaching at risk populations and providing access to screening and effective treatment. Stigma around viral hepatitis persists and must be addressed. The WHO goal of global elimination by 2030 is a worthy aim, but remains ambitious and the coronavirus 2019 pandemic undoubtedly has set back progress. This review article will focus on hepatitis A to E, highlighting problems that have been resolved in the field over the past decade, those that remain to be …

Sources of geomaterials in the Sicani Mountains during the Early Middle Ages: A case study of Contrada Castro, central western Sicily
2022
From 2017, an unknown rural settlement in Contrada Castro at Corleone (Palermo Province, western Sicily) was investigated as part of the `Harvesting Memories Project¿. The stratigraphic sequence, supported by radiocarbon dating, has demonstrated a reoccupation of a pre-Roman site during the transition between the Byzantine and Islamic periods. In particular, the main occupation occurred in the late 8th¿9th century when pottery kilns and a probable warehouse were constructed. During the 10th¿11th century, a new structure with different orientations replaced the previous buildings that had already collapsed. Specifically focusing on a perspective of the household production and its relationsh…
Associations between infant and maternal characteristics measured at child age 5 months and maternal feeding styles and practices up to child age two…
2022
Facilitating positive feeding practices from infancy may be an important strategy to prevent childhood overweight and obesity. Since the feeding situation early in life constitutes a bidirectional relationship, it is important to understand the impact of both maternal and infant characteristics on maternal feeding practices to intervene in a customized and tailored way. Few studies have concurrently examined associations between maternal and infant characteristics in relation to early maternal feeding practices. The aim of the present study was to explore potential associations between infant and maternal characteristics measured at child age five months, and maternal feeding styles and pra…

Evolutionary processes in the emergence and recent spread of the syphilis agent, Treponema pallidum
2022
Abstract The incidence of syphilis has risen worldwide in the last decade in spite of being an easily treated infection. The causative agent of this sexually transmitted disease is the bacterium Treponema pallidum subspecies pallidum (TPA), very closely related to subsp. pertenue (TPE) and endemicum (TEN), responsible for the human treponematoses yaws and bejel, respectively. Although much focus has been placed on the question of the spatial and temporary origins of TPA, the processes driving the evolution and epidemiological spread of TPA since its divergence from TPE and TEN are not well understood. Here, we investigate the effects of recombination and selection as forces of genetic diver…
The Role of Satisfaction With Job and Cognitive Trauma Processing in the Occurrence of Secondary Traumatic Stress Symptoms in Medical Providers Worki…

Time-like Proton Form Factors with Initial State Radiation Technique
2022
Electromagnetic form factors are fundamental quantities describing the internal structure of hadrons. They can be measured with scattering processes in the space-like region and annihilation processes in the time-like region. The two regions are connected by crossing symmetry. The measurements of the proton electromagnetic form factors in the time-like region using the initial state radiation technique are reviewed. Recent experimental studies have shown that initial state radiation processes at high luminosity electron-positron colliders can be effectively used to probe the electromagnetic structure of hadrons. The BABAR experiment at the B-factory PEP-II in Stanford and the BESIII experim…
Anomalous Behavior of Zirconium and Hafnium in Volcanic Fumarolic Fluids
2022
The Zirconium and Hafnium concentrations in worldwide fumaroles fed by magmatic fluids reveal that the Zr/Hf ratio is inversely related to the temperature of emission. Lower Zr/Hf ratio values below the chondritic signature are found in fluids having the highest temperature while super-chondritic Zr/Hf ratio values are found in lower temperatures. Sub-chondritic values of the Zr/Hf ratio may be related to larger volatility of Hf-chloride gas species with respect to Zr-Cl gas species, while super-chondritic ratios may correspond to fluid-rock processes resulting from cooling of uprising magmatic fluids. We propose that subchondritic Zr/Hf ratio values in fumaroles associated with high temper…
Serum Vitamin D as a Biomarker in Autoimmune, Psychiatric and Neurodegenerative Diseases.
2022
Vitamin D is a steroid hormone regulating calcium-phosphorus homeostasis, immune response and brain function. In the past thirty years, an increasing number of cohort studies, meta-analyses and randomized controlled trials (RTCs) evaluated the serum levels of 25-hydroxyvitamin D [25(OH)D], which is considered the Vitamin D status biomarker, in patients affected by neurological, psychiatric and autoimmune diseases. Although an association between low 25(OH)D serum levels and the prevalence of these diseases has been found, it is still unclear whether the serum 25(OH)D measurement can be clinically useful as a biomarker for diagnosis, prognosis and predicting treatment response in neurodegene…
Chronic Background Radiation Correlates With Sperm Swimming Endurance in Bank Voles From Chernobyl
2022
Sperm quantity and quality are key features explaining intra- and interspecific variation in male reproductive success. Spermatogenesis is sensitive to ionizing radiation and laboratory studies investigating acute effects of ionizing radiation have indeed found negative effects of radiation on sperm quantity and quality. In nature, levels of natural background radiation vary dramatically, and chronic effects of low-level background radiation exposure on spermatogenesis are poorly understood. The Chernobyl region offers a unique research opportunity for investigating effects of chronic low-level ionizing radiation on reproductive properties of wild organisms. We captured male bank voles (Myo…

2022
European Union Member States are called upon to meet internationally proposed environmental goals. This study is based, in particular, on the recommendation of the European Union (EU), which encourages Member States to pursue effective policies to reduce greenhouse gas (GHGs) emissions, including through appropriate changes in the behavioral habits of citizens. In this respect, among the main sectors involved, transport and mobility should certainly be mentioned. National institutions should be adequately involved in order to achieve the objectives set; in this regard, universities must certainly be considered for their educational value. These latter, for instance, could commit to improvin…

A Group Intervention to Promote Resilience in Nursing Professionals: A Randomised Controlled Trial
2022
In this study, a new group intervention program to foster resilience in nursing professionals was tested for efficacy. In total, 72 nurses were recruited and randomised to either an intervention condition or to a wait list control condition. The study had a pre-test, post-test, follow-up design. The eight-week program targeted six resilience factors: cognitive flexibility, coping, self-efficacy, self-esteem, self-care, and mindfulness. Compared to the control group, the intervention group reported a significant improvement in the primary outcome mental health (measured with the General Health Questionnaire) from pre-test (M = 20.79; SD = 9.85) to post-test (M = 15.81; SD = 7.13) with an est…
Mitigating Coopetition Tensions: The Forgotten Formation Stage
2022
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. Coopetition entails tensions inherent to collaboration with competitors. This paper focuses on the coopetition formation stage and its effects on the development of tensions. We performed interviews with executives of coopeting firms, create case studies of organizations that initiate and execute coopetition agreements for other firms, and then study firms engaged in mutual coopetition. While this study confirms previous findings that coopetition formation can be deliberate or emergent, it also reveals that the two approaches differ in strategy …
Axonemal Symmetry Break, a New Ultrastructural Diagnostic Tool for Primary Ciliary Dyskinesia?
2022
Diagnosis testing for primary ciliary dyskinesia (PCD) requires a combination of investigations that includes study of ciliary beat pattern by high-speed video-microscopy, genetic testing and assessment of the ciliary ultrastructure by transmission electron microscopy (TEM). Historically, TEM was considered to be the “gold standard” for the diagnosis of PCD. However, with the advances in molecular genetic techniques, an increasing number of PCD variants show normal ultrastructure and cannot be diagnosed by TEM. During ultrastructural assessment of ciliary biopsies of patients with suspicion of PCD, we observed an axonemal defect not previously described that affects peripheral doublets tilt…
Umbilical Cord Mesenchymal Stromal Cells for Cartilage Regeneration Applications
2022
Chondropathies are increasing worldwide, but effective treatments are currently lacking. Mesenchymal stromal cell (MSCs) transplantation represents a promising approach to counteract the degenerative and inflammatory environment characterizing those pathologies, such as osteoarthritis (OA) and rheumatoid arthritis (RA). Umbilical cord- (UC-) MSCs gained increasing interest due to their multilineage differentiation potential, immunomodulatory, and anti-inflammatory properties as well as higher proliferation rates, abundant supply along with no risks for the donor compared to adult MSCs. In addition, UC-MSCs are physiologically adapted to survive in an ischemic and nutrient-poor environment a…
Multiscale Investigation of the Structural, Electrical and Photoluminescence Properties of MoS2 Obtained by MoO3 Sulfurization
2022
In this paper, we report a multiscale investigation of the compositional, morphological, structural, electrical, and optical emission properties of 2H-MoS2 obtained by sulfurization at 800 °C of very thin MoO3 films (with thickness ranging from ~2.8 nm to ~4.2 nm) on a SiO2/Si substrate. XPS analyses confirmed that the sulfurization was very effective in the reduction of the oxide to MoS2, with only a small percentage of residual MoO3 present in the final film. High-resolution TEM/STEM analyses revealed the formation of few (i.e., 2–3 layers) of MoS2 nearly aligned with the SiO2 surface in the case of the thinnest (~2.8 nm) MoO3 film, whereas multilayers of MoS2 partially standing up with r…
The epistemological complexity of ideal care : long-term care professionals’ perspectives
2022
The article elaborates what aspects of knowledge eldercare workers describe concerning everyday long-term care practices. The article utilises a thematic analysis of Finnish long-term care workers’ semi-structured interviews (n = 25), and in doing so, it contributes to the discussion concerning the epistemological basis of care. The analysis specifies four aspects of knowledge in long-term care work: objective/objectifying, particular, corporeal and tacit. In line with existing literature on knowledge and care, the findings indicate that rational-technical epistemological approaches are insufficient when complex and fluid care relations are concerned. Moreover, cognitive impairments and oth…

The landscape of childhood. A study of young adults’ memories in the face of childhood nature
2022
I denne studien undersøker vi hvilke minner som kommer til syne når unge voksne møter barndommens nærnatur igjen, og hvordan kan vi forstå disse minnene. Arbeidet tar utgangspunkt i en kulturell fenomenologisk forståelse. Åtte unge voksne har gått tilbake til sine barndomssteder i skolens nærnatur sammen med en av forskerne. De har gått, klatret og snakket om friluftsliv, lek og lekesteder ute i barndommen. Metoden åpner for å studere komplekse, kroppsliggjorte og stedsspesifikke minner og erfaringer knyttet til konkrete steder, aktiviteter og sosiale relasjoner. Teoretisk bygger studien på fenomenologen Merleau-Pontys beskrivelser av hvordan mennesker bebor verden, Rosas teori om resonans …

Muscular strength is a critical component of physical health. The aim of this cross-sectional study was to examine age- and sex-based differences in functional strength and rates of referral for education in a large international sample of Special Olympics athletes. A total of 30,358 (male = 19,661) adult (20–69 years old) athlete functional strength records were utilized from the Special Olympics Healthy Athletes database. Descriptive statistics were computed for the following tests: timed sit to stand, partial sit-up, grip strength, and seated push-up. Analyses of variance with Fisher-Hayter pairwise comparisons generally supported age-related decreases in strength among both males and fe…
Design and validation of a wireless Body Sensor Network for integrated EEG and HD-sEMG acquisitions
2022
Sensorimotor integration is the process through which the human brain plans the motor program execution according to external sources. Within this context, corticomuscular and corticokinematic coherence analyses are common methods to investigate the mechanism underlying the central control of muscle activation. This requires the synchronous acquisition of several physiological signals, including EEG and sEMG. Nevertheless, physical constraints of the current, mostly wired, technologies limit their application in dynamic and naturalistic contexts. In fact, although many efforts were made in the development of biomedical instrumentation for EEG and High Density-surface EMG (HD-sEMG) signal ac…
A 16-parts-per-trillion measurement of the antiproton-to-proton charge–mass ratio
2022
The standard model of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter in the observable universe, which inspires experiments to compare the fundamental properties of matter/antimatter conjugates with high precision. Our experiments deal with direct investigations of the fundamental properties of protons and antiprotons, performing spectroscopy in advanced cryogenic Penning trap systems. For instance, we previously compared the proton/antiproton magnetic moments with 1.5 parts per billion fractional precision, which improved upon previous best measurements by a factor of greater than 3,0…
