Beyond Positive Affect: Discrete Positive Emotions Differentiate Major Depression from Social Anxiety Disorder
Authors: Chin Angela A. , Sweet Alison M. , Taylor Charles T.
Published: February 2023

Background

Social anxiety disorder (SAD) and major depressive disorder (MDD) are both associated with diminished global positive affect. However, little is known about which specific positive emotions are affected, and which positive emotions differentiate MDD from SAD.

Methods

Four groups of adults recruited from the community were examined (N = 272): control group (no psychiatric history;n = 76), SAD without MDD group (n = 76), MDD without SAD group (n = 46), and comorbid group (diagnoses of both SAD and MDD;n = 74). Discrete positive emotions were measured with the Modified Differential Emotions Scale, which asked about the frequency of 10 different positive emotions experienced during the past week.

Results

The control group had higher scores on all positive emotions compared to all three clinical groups. The SAD group had higher scores on awe, inspiration, interest, and joy compared to the MDD group, and higher scores on those emotions, as well as amusement, hope, love, pride, and contentment, than the comorbid group. MDD and comorbid groups did not differ on any positive emotions. Gratitude did not differ significantly between clinical groups.

Conclusion

Adopting a discrete positive emotion approach revealed shared and distinct features across SAD, MDD, and their comorbidity. We consider possible mechanisms underlying transdiagnostic vs. disorder-specific emotion deficits.

Published: February 2023

The effect of steam thermotherapy on Botrytis spp. populations in strawberry transplants was evaluated. Tray plants rooted in 0.2 L peat plugs of seasonal flowering cvs. Falco, Sonsation, and Soprano, and everbearing cvs. Favori and Murano were pre-treated with steam at 37 °C for 1 h, followed by 1 h at ambient temperature and air humidity, and then 2 or 4 h steam treatment at 44 °C. Except for one cultivar with a slight reduction in yield, there were no negative effects on plant performance. Compared to untreated transplants, mean incidence of Botrytis on the five cultivars was reduced by 43 and 86% with the 2 and 4 h treatments, respectively. Within cultivars the reduction was significant in 2 and 3 experiments following the 2 and 4 h treatments, respectively. Sclerotia from four different isolates of Botrytis were subjected to treatment including 4 h of steam thermotherapy and subsequently tested for viability. Following 14 days of incubation, 90 to 100% (mean 97%) of treated sclerotia failed to produce mycelial growth compared with untreated sclerotia, which all germinated and produced mycelia. Botrytis isolates recovered from both treated and untreated strawberry transplants were tested for resistance to seven fungicides, including boscalid, fenhexamid, fludioxonil, fluopyram, pyraclostrobin, pyrimethanil and thiophanate-methyl. Multiple fungicide resistance was common; 35.5% of isolates were resistant to fungicides from at least three FRAC groups. Results indicate that steam thermotherapy treatment strongly reduces populations of Botrytis spp., including fungicide-resistant strains, in strawberry transplants with negligible negative impacts on the transplants.
A non-iterative parameter identification procedure for the non-local Gurson–Tvergaard–Needleman model based on standardized experiments

Published: February 2023

Damage mechanics models exhibit favorable properties such as the intrinsic influence of stress triaxiality on damage evolution and the prediction of crack initiation as well as propagation leading to structural failure. However, their application requires advanced expertise hindering the transfer of these models into industrial practice, especially since the parameter calibration is a key obstacle. In this paper, a simplified procedure is proposed for a non-local extension of the Gurson–Tvergaard–Needleman model (GTN), which is a highly accepted model for ductile failure of metals. The procedure is iteration free and requires experimental input data from only two standardized tests. The parameters are determined using look-up diagrams created on the basis of systematic simulations and made available for different material behavior covering the majority of ductile metals. Benchmark tests for three different steels are conducted to evaluate the robustness of the proposed procedure. The reliability of the GTN model is validated for all investigated materials.
Climbing the Career Ladder Does Not Make You Happy: Well-being Changes in the Years Before and After Becoming a Leader
Authors: Asselmann Eva , Specht Jule
Published: February 2023

Subjective well-being tends to be higher in leaders vs. non-leaders. However, do these differences come from selection effects (e.g., because higher subjective well-being predisposes for occupational success) or from within-person well-being changes before and after becoming a leader? This question remains largely unresolved. Previous research suggests that becoming a leader might be a double-edged sword and affect subjective well-being positively but also negatively (e.g., due to more power but also more stress). Using data from the German Socio-Economic Panel Study (N = 25,674), we examined (a) well-being differences between employees who did vs. did not start a leadership position and (b) well-being changes before and after becoming a leader. Compared to non-leaders, leaders were more satisfied with their lives, happier, and less sad in the years before and after starting a leadership position. Leaders became slightly more satisfied with their lives in the five years before and five years after becoming a leader. Happiness, sadness, and anxiety did not change, but anger increased after starting a leadership position. These findings support the idea that differences in subjective well-being between leaders and non-leaders largely stem from selection effects, while starting a leadership position might even lower specific well-being facets.
Automating Electronic Health Record Data Quality Assessment
Authors: Ozonze Obinwa , Scott Philip J. , Hopgood Adrian A.
Published: February 2023

Information systems such as Electronic Health Record (EHR) systems are susceptible to data quality (DQ) issues. Given the growing importance of EHR data, there is an increasing demand for strategies and tools to help ensure that available data are fit for use. However, developing reliable data quality assessment (DQA) tools necessary for guiding and evaluating improvement efforts has remained a fundamental challenge. This review examines the state of research on operationalising EHR DQA, mainly automated tooling, and highlights necessary considerations for future implementations. We reviewed 1841 articles from PubMed, Web of Science, and Scopus published between 2011 and 2021. 23 DQA programs deployed in real-world settings to assess EHR data quality (n = 14), and a few experimental prototypes (n = 9), were identified. Many of these programs investigate completeness (n = 15) and value conformance (n = 12) quality dimensions and are backed by knowledge items gathered from domain experts (n = 9), literature reviews and existing DQ measurements (n = 3). A few DQA programs also explore the feasibility of using data-driven techniques to assess EHR data quality automatically. Overall, the automation of EHR DQA is gaining traction, but current efforts are fragmented and not backed by relevant theory. Existing programs also vary in scope, type of data supported, and how measurements are sourced. There is a need to standardise programs for assessing EHR data quality, as current evidence suggests their quality may be unknown.
Estimating meaningful thresholds for multi-item questionnaires using item response theory
Authors: Terluin Berend , Koopman Jaimy E. , Hoogendam Lisa , Griffiths Pip , Terwee Caroline B. , Bjorner Jakob B.
Published: February 2023

Purpose

Meaningful thresholds are needed to interpret patient-reported outcome measure (PROM) results. This paper introduces a new method, based on item response theory (IRT), to estimate such thresholds. The performance of the method is examined in simulated datasets and two real datasets, and compared with other methods.

Methods

The IRT method involves fitting an IRT model to the PROM items and an anchor item indicating the criterion state of interest. The difficulty parameter of the anchor item represents the meaningful threshold on the latent trait. The latent threshold is then linked to the corresponding expected PROM score. We simulated 4500 item response datasets to a 10-item PROM, and an anchor item. The datasets varied with respect to the mean and standard deviation of the latent trait, and the reliability of the anchor item. The real datasets consisted of a depression scale with a clinical depression diagnosis as anchor variable and a pain scale with a patient acceptable symptom state (PASS) question as anchor variable.

Results

The new IRT method recovered the true thresholds accurately across the simulated datasets. The other methods, except one, produced biased threshold estimates if the state prevalence was smaller or greater than 0.5. The adjusted predictive modeling method matched the new IRT method (also in the real datasets) but showed some residual bias if the prevalence was smaller than 0.3 or greater than 0.7.

Conclusions

The new IRT method perfectly recovers meaningful (interpretational) thresholds for multi-item questionnaires, provided that the data satisfy the assumptions for IRT analysis.
Mercury movement from Hg-enriched wetland soils to arboreal food webs: a weak role for folivory
Authors: Zabala Jabi , Frederick Peter
Published: February 2023

Mercury (Hg) is a toxicant of concern, particularly in aquatic food webs. Mercury can move to terrestrial systems through consumption of aquatic prey or emergence of insects with aquatic larval phases. The possible movement of Hg from sediments to wetland plants and into terrestrial food webs though primary consumers has received less attention. We investigated differences and correlations in Hg in soil, wood and leaves of willows (Salix caroliniana) and folivorous beetles from a wetland with enhanced levels of Hg. Further, we compared samples from tree islands that had enriched Hg in soil through bird guano with control islands. Hg in any sample type did not correlate with Hg in any other sample type from the same island. We found higher [Hg] in soils and significantly higher [Hg] in leaves from colony islands, while [Hg] in beetles appeared to be higher in control islands. In any case, despite comparatively high [Hg] in soil and leaves, Hg in folivorous beetles was below detection levels and lower than that reported from other studies. We conclude that movement of Hg from wetland trees to terrestrial food webs through wetland vegetation is negligible in this ecosystem.
Effects of acute metaphedrone exposure on the development, behaviour, and DNA integrity of zebrafish (Danio rerio)
Authors: Ribeiro Ondina , Ribeiro Cláudia , Félix Luís , Gaivão Isabel , Carrola João Soares
Published: February 2023

The presence of new psychoactive substances (NPS), like metaphedrone (3-MMC), in aquatic environments raises concern about the potential negative effects on ichthyofauna. Therefore, the aim of this study was to evaluate the potential effects of 3-MMC on zebrafish embryonic development, behaviour, and DNA integrity. For that, embryos were exposed during 96 h post-fertilization to 3-MMC (0.1, 1, 10, and 100 µg/L). Overall, an increase in the eye area of zebrafish larvae was observed for the concentrations of 1 μg/L (increase of 24%) and 100 μg/L (increase of 25%) in comparison with the control group. Genetic damage was noted at the highest concentration (100 µg/L) with an increase of DNA damage (increase of 48%) and hyperactivity and disorganised swimming pattern characterised by an increase in speed (increase of 49%), total distance moved (increase of 53%), and absolute turn angle (increase of 48%) of zebrafish larvae. These findings pointed that, at environmental low levels, 3-MMC harmful effects are not expected to occur during critical development life stages of fish.

Graphical Abstract
Salafism as Gramscian informed vanguardism
Authors: Ramaioli Massimo
Published: February 2023

In this study, I offer a categorization of Salafism based on the concept of vanguardism. Vanguardism suggests how Salafis inhabit the political domain, by posing as the vanguard of a privileged group endowed with a historical mission. Relatedly, I summon the Gramscian concept of “philosophy of praxis.” With this, I intend to reconfigure Wiktorowicz’s classificatory scheme predicated on too stark an opposition between ‘aqīdah (theory) and manhaj (method). The philosophy of praxis accounts for the inherent tension between these two domains. Such tension is manifest in Salafis’ ambiguities, compromises, internal rifts, ideological adjustments, and revisions. Two related Gramscian concepts, historical bloc and modern Prince, bring such considerations more immediately into the political. They highlight, respectively, the political-historical context in which Salafis operate and the political-historical role they play as instances of vanguardism. I then put forth my classificatory scheme in the form of a typology. One axis is represented by the attitude towards the “historical bloc” (pro or anti) and the kind of vanguard posturing that emerges out of it (support, creation, or activation). The other axis is represented by the specific framing of the “Enemy” category on the part of the Salafi vanguard (historical/institutional or essential/identitarian), and the stance they consequently assume towards it (compromise/accommodation or rejection/denunciation). The resulting classification offers six categories (accommodationists, partisans, delayers, agitators, mobilizers, and belligerents). Stressing the fundamental political nature of contemporary Salafism—its vanguardism—they account for its inscription in a specific, modern way of thinking and acting the political.
Behaviour of self-centring shear walls—A state of the art review
Authors: Javadi Mehdi , Hassanli Reza , Rahman Md Mizanur , Karim Md Rajibul
Published: February 2023

The application of unbonded post-tensioning (PT) in structural walls has led to the development of advanced self-centring (rocking) shear wall systems that has significant advantages, including accelerated construction due to the incorporation of prefabricated elements and segmental construction for different materials (e.g., concrete, masonry, and timber), reduced residual drifts, and little damage upon extreme seismic and wind loads. Concrete, masonry, and timber are often used for the construction of unbonded PT structural wall systems. Despite extensive research since the 1980s, there are no well-established design guidelines available on the shear wall configuration with the required energy dissipation system, joint’s locations and acceptance criteria for shear sliding, confinement, seismic performance factors, PT loss, PT force range and residual drifts of shear walls subjected to lateral loads. In this research a comprehensive state-of-the-art literature review was performed on self-centring shear wall system. An extensive study was carried out to collect a database of 100 concrete, masonry, and self-centring shear wall tests from the literature. The established database was then used to review shear walls’ configurations, material, and components to benchmark requirements applicable for design purposes. The behaviour of concrete, masonry and timber shear walls were compared and critically analysed. The general behaviour, force-displacement performance of the walls, ductility, and seismic response factors, were critically reviewed and analysed for different self-centring wall systems to understand the effect of different parameters including configurations of the walls, material used for construction of the wall (concrete, masonry, timber) and axial stress ratio. The outcome of this research can be used to better understand the behaviour of self-centring wall system in order to develop design guidelines for such walls.
On recovering block cipher secret keys in the cold boot attack setting
Authors: Banegas Gustavo , Villanueva-Polanco Ricardo
Published: February 2023

This paper presents a general strategy to recover a block cipher secret key in the cold boot attack setting. More precisely, we propose a key-recovery method that combines key enumeration algorithms and Grover’s quantum algorithm to recover a block cipher secret key after an attacker has procured a noisy version of it via a cold boot attack. We also show how to implement the quantum component of our algorithm for several block ciphers such as AES, PRESENT and GIFT, and LowMC. Additionally, since evaluating the third-round post-quantum candidates of the National Institute of Standards and Technology (NIST) post-quantum standardization process against different attack vectors is of great importance for their overall assessment, we show the feasibility of performing our hybrid attack on Picnic, a post-quantum signature algorithm being an alternate candidate in the NIST post-quantum standardization competition. According to our results, our method may recover the Picnic private key for all Picnic parameter sets, tolerating up to 40% of noise for some of the parameter sets. Furthermore, we provide a detailed analysis of our method by giving the cost of its resources, its running time, and its success rate for various enumerations.
The Experience of International Students: Biographical Narratives and Identities
Authors: Birindelli Pierluca
Published: February 2023

This article presents the findings of a qualitative and comparative study on the cultural experience of international students in North and South Europe. I employ a narrative approach and the focus of the research revolves around the autoethnographies of 25 international students in Helsinki and 25 in Florence. The narratives were prompted by in-depth interviews following a template divided into the three phases of travel conceived as a rite of passage: departure–preliminal, transition–liminal, arrival–postliminal. To explore the meaning of geographical mobility in the lives of these young people, I sketched a series of self-identity types connected to mobility experiences: the Fated, whose biographical premises are all pushing-pulling toward the status of international student; the Academic, who is fascinated by the idea of becoming a worldly intellectual and sees the PhD as a natural step; the Globetrotter, whose mobility is an end in itself: the goal is the next city-country; the Explorer, who is abroad looking for new cultural challenges, with a genuine desire to discover and understand specific places and people; the Runaway, who feels like a stranger at home and is escaping abroad for political or existential reasons. I believe that the interpretation of international students’ sense of self-identity can be fruitfully achieved through the narrative path I have constructed (or a similar one).
Stigma, Depression, Suicidal Thoughts and Coping of Sexual Minority Youth Raised in Conservative Versus Mainstream Denominations of Christianity: A Mixed Method Study
Authors: van Bergen Diana , Smit Alette , Feddes Allard R.
Published: February 2023

We quantitatively examined whether Dutch sexual minority youth raised with conservative Protestantism reported more family- and self-stigmatization, suicidal ideation, and depression than those socialized by Catholicism or Mainline Protestantism. Subsequently, we qualitatively examined how youth raised with conservative Protestantism coped with sexuality identity and mental health challenges. Survey data came from sexual minority youth (N = 584, age 16–25) raised with conservative Protestantism (Evangelical/Pentecostal n = 44 and Dutch Orthodox Reformed n = 88, Mainline Protestantism n = 117, and Catholicism n = 335). Group differences in associations were studied through univariate analysis of variance. Next, thematic and interpretative analyses of six interviews of survey respondents raised with conservative Protestantism were performed. Sexual minority youth raised with Evangelicalism/Pentecostalism reported significant higher levels of family stigmatization and suicidal ideation than youth raised with other Christian religions. They addressed these challenges by religious coping, formulating critiques of stigma, and support from Christian self-help groups.
Judging a book by its older adult cover: age-related expectations and parental preference for children’s books
Authors: Bellingtier Jennifer A. , Schenker Lena-Emilia , Weber Anna L.
Published: February 2023

As they typically have limited direct contact, children’s attitudes towards older adults have more opportunity to be shaped by other social influences such as their parents and children’s literature. Children’s books have been noted for their tendency to portray older adults in stereotypical ways and their tendencies to underrepresent older adults. We investigated how the portrayal of older adults as major versus supporting characters, as well as parents’ age-related expectations were related to parental preference for children’s books. We designed 24 children’s book covers that depicted an older adult as a main character, a younger adult as a main character, or only children. One-hundred-seventy-five parents of children ages 0–12 rated their preference for the covers, their age-related expectations for the books’ stories, and their personal aging expectations. Parents preferred covers featuring only children, and this preference was stronger for parents with more positive personal aging expectations. Cover preference was further predicted by age-related story expectations. When parents expected a book to conform to older-age stereotypes, they liked that particular cover less. Controlling for parents’ age-related story expectations for each book resulted in near equal levels of preference for all types of book covers. Carefully designed children’s books could provide an opportunity to increased vicarious intergenerational contact. These finding suggests that parents’ interest in selecting these books for their children will be higher when they do not perceive the books to align with older-age stereotypes.
Development and validation of a transient simulation model of a full-scale PCM embedded radiant chilled ceiling

Published: February 2023

The recent significant rise in space cooling energy demand due to the massive use of air-conditioning systems has adversely changed buildings’ energy use patterns globally. The updated energy technology perspectives highlight the need for innovative cooling systems to address this growing cooling demand. Phase change material embedded radiant chilled ceiling (PCM-RCC) has lately acquired popularity as they offer more efficient space cooling together with further demand-side flexibility. Recent advancements in PCM-RCC applications have increased the necessity for reliable simulation models to assist professionals in identifying improved designs and operating settings. In this study, a transient simulation model of PCM-RCC has been developed and validated using measured data in a full-scale test cabin equipped with newly developed PCM ceiling panels. This model, developed in the TRNSYS simulation studio, includes Type 399 that uses the Crank-Nicolson algorithm coupled with the enthalpy function to solve transient heat transfer in PCM ceiling panels. The developed model is validated in both free-running and active operation modes, and its quality is then evaluated using several validation metrics. The results obtained in multiple operating scenarios confirm that the model simulates the transient behaviour of the PCM-RCC system with an accuracy within ±10%. Aided by this validated model, which offers the user detailed flexibilities in the system design and its associated operating schemas, PCM-RCC’s potentials regarding peak load shifting, energy savings, and enhanced thermal comfort can be investigated more reliably.

Proliferative diabetic retinopathy (PDR) the sequel of diabetic retinopathy (DR), a frequent complication of diabetes mellitus (DM), is the leading cause of blindness in the working-age population. The current screening process for the DR risk is not sufficiently effective such that often the disease is undetected until irreversible damage occurs. Diabetes-associated small vessel disease and neuroretinal changes create a vicious cycle resulting in the conversion of DR into PDR with characteristic ocular attributes including excessive mitochondrial and retinal cell damage, chronic inflammation, neovascularisation, and reduced visual field. PDR is considered an independent predictor of other severe diabetic complications such as ischemic stroke. A “domino effect” is highly characteristic for the cascading DM complications in which DR is an early indicator of impaired molecular and visual signaling. Mitochondrial health control is clinically relevant in DR management, and multi-omic tear fluid analysis can be instrumental for DR prognosis and PDR prediction. Altered metabolic pathways and bioenergetics, microvascular deficits and small vessel disease, chronic inflammation, and excessive tissue remodelling are in focus of this article as evidence-based targets for a predictive approach to develop diagnosis and treatment algorithms tailored to the individual for a cost-effective early prevention by implementing the paradigm shift from reactive medicine to predictive, preventive, and personalized medicine (PPPM) in primary and secondary DR care management.
Education and internal migration: evidence from a child labor reform in Spain
Authors: González Chapela Jorge , Jiménez-Martín Sergi , Vall Castello Judit
Published: February 2023

We exploit a country-wide child labor regulation that eliminated the difference in school/work alternatives for children born at the beginning and the end of the year to identify the causal effect of education on migration at low levels of schooling. By not relying on changes to the school system, we are more confident that our results are not driven by unobserved changes in school quality evolving differentially across regions. The results of a difference-in-differences methodology combined with an exploration of maternal characteristics and a regression discontinuity design suggest that internal migration hardly changed after the reform. A consideration of the external validity of this finding is also provided.
Integration matters: Combining socio-cultural and biophysical methods for mapping ecosystem service bundles
Authors: Cusens Jarrod , Barraclough Alicia D. , Måren Inger Elisabeth
Published: February 2023

Ecosystem services (ESs) play an important role in sustainable landscape management. People value ESs in diverse ways encompassing social and ecological domains and we need to bring these different values together. We used social-cultural and biophysical methods to map a diverse set of ESs at two spatial scales in a UNESCO Biosphere Reserve in Norway. The ESs bundled into three distinct social–ecological system archetypes which were similar in their distribution and relative ES values at both spatial scales. The bundles were also well matched to relative ESs values of the Biosphere Reserve zones (core, buffer, and transition) indicating that the bundles capture the social–ecological systems of the zones. We argue that it is important to consider the social–ecological context of the zones to provide sufficient knowledge to inform management. Our work has the capacity to contribute to sustainable land management that takes biocultural values into consideration.
Influence of mixing speed, solids concentration and enzyme dosage on dry solids yield and protein recovery during enzymatic hydrolysis of sardine (Sardina pilchardus) processing by-products using Alcalase 2.4L: a multivariable optimisation approach
Authors: Chiodza Kudzai , Goosen Neill J.
Published: February 2023

Yield and protein recovery are important variables for process design, which cannot be achieved using degree of hydrolysis (DH). Even though it is known that mixing speed and solids concentration affect mass and energy transfer in bioprocess reaction, previous research has not provided a clear relationship between these two variables and their effect on yield of dry solids and protein recovery during enzyme hydrolysis. The yield of dry solids and protein recovery from enzyme hydrolysis of sardine processing by-products was compared at different levels of mixing speed (100–300 rpm), solids concentration (26–50%) and enzyme dosage (1.318–4.682%). Results showed that low mixing speed (100 rpm), low solids concentration (26–30.8%) and high enzyme dosage (4.682%) optimised degree of hydrolysis to 25.7%, yield of dry solids to 69.1% and protein recovery to 83.0%. Under these conditions, protein loss to emulsion and sludge were minimised to 5.82% and 11.2%, respectively. Although low solids concentration resulted in high solids yield and high protein recovery due to favourable mass transfer effects, hydrolysing material under these conditions will come at a significant cost of larger equipment designs and energy cost for mixing and downstream processing because of the large volume of water to be handled. There is therefore a need for a holistic approach to enzyme hydrolysis optimisation studies, with downstream processing in mind. The significant findings of this study show the impact of process variables and their interaction, particularly solids concentration, on process performance using multivariable optimisation.
Well-to-Wheels emission inventory for the passenger vehicles of Bogotá, Colombia
Authors: Cuéllar-Álvarez Y. , Guevara-Luna M. A. , Belalcázar-Cerón L. C. , Clappier A.
Published: February 2023

Emission inventories are essential in air quality management; they identify the main sources of atmospheric pollution and define mitigation strategies. Most vehicle emission inventories estimate direct emissions, including combustion and, in some cases, wear and dust resuspension emissions. However, emission inventories typically do not account for indirect fuel production, storage, and transportation emissions. This study quantifies the Well-to-Wheels emissions from all passenger transport vehicles in Bogotá, Colombia. This inventory estimates direct emissions from fuel combustion, wear and dust resuspension, and indirect emissions. This study analyzes all vehicle technologies and fuels used to transport passengers in the city and estimates PM2.5, SO2, CO, NOx, Volatile Organic Compounds, and greenhouse gas (CO2-Eq) emissions. COPERT model was adapted to local conditions to estimate direct combustion emissions and European Monitoring and Evaluation Program and U.S. Environmental Protection Agency methodologies to estimate wear and dust resuspension emissions. We used the OpenLCA® Software, the ecoinvent 3.4 database, and all locally available information to calculate indirect emissions. As far as is known, this is the first Well-to-Wheels emissions inventory considering all passenger vehicles in Bogotá. To evaluate the consistency of this study, we compared results from this inventory with those published in Bogotá and other cities worldwide. This study highlights the importance of including other emission sources than vehicle fuel combustion in emission inventories.
Bone Stress Injuries in Runners Using Carbon Fiber Plate Footwear
Authors: Tenforde Adam , Hoenig Tim , Saxena Amol , Hollander Karsten
Published: February 2023

The introduction of carbon fiber plate footwear has led to performance benefits in runners. The mechanism for these changes in running economy includes altered biomechanics of the foot and ankle. The association of this footwear with injuries has been a topic of debate clinically, but not described in the literature. In this Current Opinion article, illustrated by a case series of five navicular bone stress injuries in highly competitive running athletes, we discuss the development of running-related injuries in association with the use of carbon fiber plate footwear. While the performance benefits of this footwear are considerable, sports medicine providers should consider injuries possibly related to altered biomechanical demands affecting athletes who use carbon fiber plate footwear. Given the introduction of carbon fiber plate footwear into athletics and other endurance sports, strategies may be required to reduce risk of injury due to altered foot and ankle mechanics. This article is intended (1) to raise awareness on possible health concerns around the use of carbon fiber plate footwear, (2) to suggest a slow gradual transition from habitual to carbon fiber plate footwear, and (3) to foster medical research related to carbon fiber plate technology and injuries.

Further, the strength analysis of the generated substitution boxes is carried out using the well-known standards, namely bijectivity, non-linearity, strict avalanche criterion, bit independence criterion, XOR table and differential invariant. As application, an encryption algorithm is proposed that can be employed to strengthen any kind of secure communication. The presented algorithm is mainly based on the Shannon idea of substitution–permutation network where the process of substitution is performed by the proposed $$S_8$$

semifield substitution boxes and permutation operation is performed by the binary cyclic shift of substitution box transformed data. In addition, the proposed encryption algorithm utilizes two different chaotic maps. To ensure the appropriate utilization of these chaotic maps, we carry out in-depth analyses of their behavior in the context of secure communication and apply the pseudo-random sequences of chaotic maps in the proposed image encryption algorithm accordingly.
It’s Unfair! Non-price Exploitation in ICT Patents Licenses
Authors: Galli Niccolò , Botta Marco
Published: February 2023

This paper analyses controversial patent licensing conditions in the Information Communication Technology (ICT) sector as “unfair trading conditions” under Art. 102(a) TFEU. It argues that the application of the Technology Transfer Block Exemption Regulation does not prevent the assessment of patent licensing conditions under Art. 102 if the licensor is dominant in the market. Hence, the article examines four categories of controversial licensing conditions in the light of the case law of the Court of Justice of the European Union under Art. 102(a): grant-back clauses, no-challenge clauses, portfolio-wide licenses, and contract term decoupled from patent validity. Developing old precedents in new application cases, the abuse-of-dominance analysis finds that each license clause is capable of anti-competitive exploitative effects, as much as offsetting justifications. As a result, the qualification of any such clause as “unfair” needs a case-by-case approach considering the overall content of the ICT patent licensing agreement. Whether the overall efficiencies outweigh the anti-competitive effects is always a question of degree. Nonetheless, this article contributes to legal predictability by identifying the opposing economic arguments of dominant patent licensors and complaining licensees. It concludes that both parties have strings to their bows.
Experimental Investigation of a Method for Selective and Precise Laser De-Coating
Authors: Primus Tomáš , Hlavinka Josef , Zeman Pavel , Kožmín Pavel , Čermák Adam
Published: February 2023

Coatings are used in many industrial applications as a protective barrier, improving component properties such as friction, wear resistance, and thermal resistivity. When components become worn, any coatings must be thoroughly removed before performing repairs. Laser stripping is a relatively new technology developed for the entire coating removal. So far, only laser stripping of the entire coatings has been discussed in literature, but its application in selective de-coating layer by layercan extend the usage of this technique. Herein, we describe a new method of selective and precise laser de-coating layer by layer in layer thickness lower than 0,15 μm and demonstrate tise technique on two coatings, namely AlTiN and diamond-like carbon. This method is based on ablation threshold measurement and the application of low laser beam fluences for selective de-coating, layer by layer, in a defined pattern. Then the average minimal removals per layer were estimated for both coatings using first and second harmonic wavelengths. Finally, the usage of this method was proved by chemical analysis of the de-coated areas. The presented method can extend the use of laser coating stripping from actual removal of whole coatings to new areas, for example thickness measurement or inter-layer inspection of coatings.

Using the conceptual frameworks and theories of virtual tourism, telepresence and para-social interactions, this exploratory study investigates an innovative campaign employed by a nature-based wildlife tourism operator as a response to the COVID-19 lockdowns and travel restrictions of 2020/21. Insights are provided into a unique model of webcam livestreaming that is scheduled, hosted and interactive. Over 73,000 social media comments and 590 survey responses from webcam viewers were analysed and indicate that watching the livestream had positive impacts for tourism recovery and conservation action. Research findings suggest that interactive webcam travel can affect travel behaviour and conservation awareness and action in part through building and engaging online communities and supporting a sense of connection with nature. This study contributes new knowledge to the emerging research on webcam livestreaming in tourism. As a subset of virtual tourism, interactive webcam travel emerges as an alternative to more costly forms of virtual reality for industry practitioners and stakeholders to engage new and old audiences, especially in the context of tourism recovery initiatives after disasters and crises that prevent or limit physical visitation.

Family responses to crises such as COVID-19 are driven by parents’ experiences. Parental history of adverse childhood experiences (ACEs) might play an important role in predicting resilience, coping capacity, and parenting practices during the COVID-19 pandemic response. The purpose of this review is to examine the impact of COVID-19 pandemic disruption on child health and well-being as influenced by the previous history of ACEs in the parents. Scopus, Google Scholar, PubMed, and PsychInfo were searched for peer-reviewed articles using the keywords “COVID-19”, “Parents or Maternal Adverse Childhood Experiences”, and “child health” or “child well-being”. Data were extracted using a literature review matrix template. Title, abstract, and full article-level reviews were conducted by two reviewers. The association between COVID-19 disruption, negative parenting, and child behavioral and emotional problems was stronger for parents with younger children with a history of high ACE scores. Parents with high ACE scores were more likely to cope poorly with childcare duties and engage in child neglect, verbal abuse, and reduced feeding frequency, specifically during the COVID-19 pandemic. The review findings support the framework of inadequate resilience and coping skills of adults with a history of ACEs during periods of stress and unpredictability such as the COVID-19 pandemic. The negative effects of these parental stressors on a child’s health and well-being are modifiable and could be mitigated by targeted interventions. Trauma-informed care should be adopted to contribute to optimum child health.

Convolutional Neural Networks (CNN) consist of various hyper-parameters which need to be specified or can be altered when defining a deep learning architecture. There are numerous studies which have tested different types of networks (e.g. U-Net, DeepLabv3+) or created new architectures, benchmarked against well-known test datasets. However, there is a lack of real-world mapping applications demonstrating the effects of changing network hyper-parameters on model performance for land use and land cover (LULC) semantic segmentation. In this paper, we analysed the effects on training time and classification accuracy by altering parameters such as the number of initial convolutional filters, kernel size, network depth, kernel initialiser and activation functions, loss and loss optimiser functions, and learning rate. We achieved this using a well-known top performing architecture, the U-Net, in conjunction with LULC training data and two multispectral aerial images from North Queensland, Australia. A 2018 image was used to train and test CNN models with different parameters and a 2015 image was used for assessing the optimised parameters. We found more complex models with a larger number of filters and larger kernel size produce classifications of higher accuracy but take longer to train. Using an accuracy-time ranking formula, we found using 56 initial filters with kernel size of 5 × 5 provide the best compromise between training time and accuracy. When fully training a model using these parameters and testing on the 2015 image, we achieved a kappa score of 0.84. This compares to the original U-Net parameters which achieved a kappa score of 0.73.

This paper reports on the second “Throughput” phase of the Tracking Machine Learning (TrackML) challenge on the Codalab platform. As in the first “Accuracy” phase, the participants had to solve a difficult experimental problem linked to tracking accurately the trajectory of particles as e.g. created at the Large Hadron Collider (LHC): given $$O(10^5)$$

individual groups that represent the particle trajectories which are approximated helical. While in the first phase only the accuracy mattered, the goal of this second phase was a compromise between the accuracy and the speed of inference. Both were measured on the Codalab platform where the participants had to upload their software. The best three participants had solutions with good accuracy and speed an order of magnitude faster than the state of the art when the challenge was designed. Although the core algorithms were less diverse than in the first phase, a diversity of techniques have been used and are described in this paper. The performance of the algorithms is analysed in depth and lessons derived.

A history of abortion is associated with cervical dysfunction during pregnancy, but there remains uncertainty about whether risk can be stratified by the abortion type, the abortion procedure, or number of previous abortions. The objective of this study was to verify the relationship between cervical dysfunction measures in pregnancies with and without a history of termination. Embase and Medline databases were searched from 01 January 1960 to 01 March 2022 resulting in a full-text review of 28 studies. The Newcastle–Ottawa Scale (NOS) was used to assess the quality and risk of bias for non-randomized studies. The meta-analysis consisted of 6 studies that met all inclusion and exclusion criteria and included a combined total of 2,513,044 pregnancies. Cervical dysfunction was defined as either cervical insufficiency/incompetence in 4 of the studies and as short cervix in the others. Results from a random-effects model using reported adjusted odds ratios (aOR) estimated an increase in the odds of 2.71 (95% CI 1.76, 4.16) for cervical dysfunction in the current pregnancy related to a history of induced or spontaneous abortion. Subgroup analyses with only induced abortions (surgical/medical) estimated an aOR of 2.54 (95% CI 1.41, 4.57), while studies limited to surgical abortions had an aOR of 4.08 (95% CI 2.84, 5.86). The risk of cervical dysfunction in the current pregnancy was also found to be dependent on the number of previous abortions. In this meta-analysis, a prior history of abortion, and specifically induced abortions, was associated with cervical dysfunction. The protocol was registered in PROSPERO (CRD42020209723).

Over the years, the devastating impact of climate change has become pronounced due to inadequate regulation for waste disposal in a developing country like Nigeria. The chicken feather-based metal oxide-rich (MOR) biochar was produced using a top-lit updraft reactor at a peak temperature of 417.2 °C to give a yield of 28.19%. The results were analyzed using Brunauer-Emmett-Teller BET, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Energy Dispersive Spectroscopy (EDS), and X-ray fluorescence spectroscopy (XRF). The result shows that the sample is mesoporous (pore diameter of 2.132 nm) with a BET surface area of 105.7 m2/g. CaO (33.147 wt%) and SO3 (25.673 wt%) were the major oxides present in notable proportions on the material surface, which were evident in the SEM micrograph. The major elemental compositions of the raw sample were oxygen (36.917 wt%) and calcium (23.690 wt%), and the major minerals present were quartz, marialite, davyne, and graphite. The present study elucidates the successful and efficient material recovery route for the preparation of adsorbents and precursors for many product synthesis processes.
