The late modernist community in the late socialistic block of flats: the issue of urban neighbourhood vitality in Poland
Authors: Nowak Marek , Siatkowski Andrzej 
Published: May 2021

AbstractThe question of the big-city neighbourhood seems important due to the discussion on the condition of modern cities. The issue is centred on the problems of sustainable development and designing social relations. The problem of the neighbourhood in relation to various forms of residence triggers a discussion rooted in the classic issues of sociology as a discipline. In the proposed article, the researchers address the problem of the late socialistic block of flats, attempting to diagnose the condition of the modern urban community in the developmental context of Central Europe, based on the neoclassic concept of ‘spatially determined social circle’. The text introduces the issues of ‘socialist modernism’ using the available Central European literature. In the research part, the data obtained from an online survey on the subject conducted in 2019 in three Polish cities and from a nationwide online survey on the same subject are statistically analysed. The linear regression analysis suggested the relative vitality of the block form of residence, whose sources are both economic and social. The problem of traditional forms of accommodation and urban neighbourhoods has become a hotly debated political issue that triggers a scientific reflection on the phenomena of integration and disintegration in cities. In this context, the issue of the vitality of the forms of housing seems important not only for diagnosis purposes but also for predictions for the forthcoming decades. The case to be analysed herein is that of the late socialistic block of flats (LSBF) in Central and Eastern European countries, which for some is an anachronistic form of residence whereas for others is a partial solution to the insufficient market dynamics intended to meet people’s housing needs. In this context, we ask four questions based on a hypothesis regarding LSBF urban neighbourhood vitality in Poland. The first question is a partly theoretical question based on the conceptualisation of social circles: To what extent does living in an LSBF modify one’s sense of belonging to a social circle? The second question concerns the empirical findings regarding the LSBF neighbourhood: What is the neighbourhood assessment related to declared residence in an LSBF? The third question concerns more specific subjects related to the LSBF neighbourhood: To what extent does living in an LSBF affect the declared depth of neighbourly relations? The fourth and last question relates to the notion of vitality of the LSBF neighbourhood: Does the length of residence in an LSBF impact the interactions between the neighbours therein? The questions concerning the present-day LSBF cannot be answered without historical references to the concept of the city of socialist modernism. It is only from the genetic perspective dating back to several decades that we can understand the dynamics of the process, which has been marked by a few fundamental tribulations.
Income Status and Life Satisfaction
Authors: FitzRoy Felix R. , Nolan Michael A. 
Published: May 2021

AbstractThe importance of both income rank and relative income, as indicators of status, has long been recognised in the literature on life satisfaction and happiness. Recently, several authors have made explicit comparisons of the relative importance of these two measures of income status, and concluded that rank dominates to the extent that reference income becomes insignificant in regressions including both these explanatory variables, and that even absolute or household income, otherwise always positively related to happiness, may lose statistical significance. Here we test this hypothesis with a large UK panel (British Household Panel Survey and Understanding Society) for 1996–2017, split by age and retirement status, and find, contrary to previous results, that rank, household income and reference income are all usually important explanatory variables, but with significant differences between subgroups. This finding holds when rank is in its often-used relative form, and also with absolute rank.

Published: May 2021

AbstractWe analyse the dynamics of a basketball which rolls around the rim of a basketball hoop. The rolling steady motions are determined, and we investigate falling, slipping, and instability. The qualitative behaviour of the global dynamics is analysed and the possible trajectories are categorised. We investigate the effect of initial conditions which cause the basketball to fall inside or outside the basket or to remain on the rim.
Perceived risk of lock-in in the front-end phase of major transportation projects
Authors: Cantarelli Chantal C. , Oglethorpe David , van Wee Bert 
Published: May 2021

AbstractLock-in is defined as the tendency to continue with an inefficient decision or project proposal. The front-end phase is critical to project success, yet most studies have focused on lock-in in the implementation phase. Moreover, little is known about the way in which decision-makers perceive the risk of lock-in. In this paper we identify determinants of lock-in in the front-end phase and we reveal decision-makers’ perceptions of risk of lock-in. Our findings show that risk attitudes towards lock-in vary with the level of risk aversion. However, this is not sufficiently acute to drive the level of regret needed to avoid lock-in. This implies that decision-makers do not accurately assess the risk of lock-in and as such their risk perceptions are a mediating factor in the formation of lock-in. Based on escalation of commitment, path dependency, and prospect theory, the main contribution lies in providing a more comprehensive understanding of lock-in in the front-end phase.
Post-Traumatic Outcomes among Survivors of the Earthquake in Central Italy of August 24, 2016. A Study on PTSD Risk and Vulnerability Factors

AbstractCentral Italy suffered from the earthquake of 2016 resulting in great damage to the community. The purpose of the present study was to determine the long-term traumatic outcomes among the population. A preliminary study aimed at obtaining the Italian translation of the first 16 item of HTQ IV part [1] which was administered, 20 months after the disaster, at 281 survivors. In backward stepwise logistic regressions models, we estimated among the respondent’s characteristics and event-related variables the best predictors of Post-Traumatic Stress Disorder (PTSD).A Confirmatory Factor Analysis (CFA) revealed a HTQ five-factors solution as best model, with satisfactory indexes of fit. HTQ held a positive correlation with both the SQD-P (r = .65,p < .05) and SQD-D subscales (r = .47, p < .05). ROC analysis suggested an area of .951 (95% CI = .917–.985) for the PTSD prediction. Basing on sensibility (.963) and specificity (.189), the best cut-off of 2.0 allowed discriminating for PTSD positive cases. After 20 months of the earthquake, the estimate prevalence of PTSD among the survivors is of 21.71% with a consistent and graded association between exposure variables and vulnerability factors (gender, age, exposure to death and home damage) and PTSD symptoms.
Applications of Hückel-Su-Schrieffer-Heeger method
Authors: Kwapisz Jan H. , Stolarczyk Leszek Z. 
Published: May 2021

AbstractThe equilibrium carbon-carbon (C-C) bond lengths inπ-electron hydrocarbons are very sensitive to the electronic ground-state characteristic. In the recent two papers by Stolarczyk and Krygowski (J Phys Org Chem, 34:e4154,e4153, 2021) a simple quantum approach, the Augmented Hückel Molecular Orbital (AugHMO) model, is proposed for the qualitative, as well as quantitative, study of this phenomenon. The simplest realization of the AugHMO model is the Hückel-Su-Schrieffer-Heeger (HSSH) method, in which the resonance integralβof the HMO model is a linear function the bond length. In the present paper, the HSSH method is applied in a study of C-C bond lengths in a set of 34 selected polycyclic aromatic hydrocarbons (PAHs). This is exactly the set of molecules analyzed by Riegel and Müllen (J Phys Org Chem, 23:315, 2010) in the context of their electronic-excitation spectra. These PAHs have been obtained by chemical synthesis, but in most cases no diffraction data (by X-rays or neutrons) of sufficient quality is available to provide us with their geometry. On the other hand, these PAHs are rather big (up to 96 carbon atoms), and ab initio methods of quantum chemistry are too expensive for a reliable geometry optimization. That makes the HSSH method a very attractive alternative. Our HSSH calculations uncover a modular architecture of certain classes of PAHs. For the studied molecules (and their fragments – modules), we calculate the values of the aromaticity index HOMA.

Published: May 2021

AbstractThe worldwide spread of the coronavirus disease (COVID-19), the absence of medical treatment and vaccination, the delayed onset of symptoms, and the rapid human-to-human transmission have led the vast majority of countries to impose strict social distancing procedures. Whereas it appears that social distancing is an effective strategy for mitigating spread, it may also result in a variety of unintended negative consequences to individuals’ psychological well-being and mental health. During the peak of the COVID-19 pandemic, the present study examined associations among some demographic variables (gender, age, marital and working statuses, and having a family member or a friend infected with COVID-19), acceptance of social distancing, mood changes, and quality of life (QoL) in Qatar, a high-income Middle Eastern Arabic-speaking country. Older, married, and working participants were more accepting of social distancing than younger, unmarried, and non-working participants, respectively. Participants indicated that, during this time, they became more distressed, upset, scared, irritable, nervous, and afraid, and less inspired and determined. In a stark contrast, more individuals indicated that they became more interested, alert, and attentive, whereas higher percentages of participants reported feeling less guilty, hostile, and ashamed. Social distancing correlated positively with negative affect, whereas social avoidances correlated positively with positive affect and with physical, psychological, social, and environmental QoL. Finally, positive affect correlated positively, and negative affect correlated negatively, with these four domains of QoL. These results highlight the need for public health and clinical providers to consider peoples’ psychological well-being and mental health during the COVID-19 pandemic.
Die Ordnung der Empfehlung
Authors: Unternährer Markus 
Published: May 2021

ZusammenfassungEmpfehlungssysteme sind Ordnungstechnologien des Digitalen. Sie bestimmen, welche Filme, Songs oder Artikel uns in welcher Reihenfolge angezeigt werden. Oftmals scheinen Empfehlungen zu personalisieren: „Ich sehe etwas ganz anderes als du.“ Der Artikel zeigt, dass auf der algorithmischen Hinterbühne gerade nicht singularisiert, sondern relationiert wird. Ich beschreibe vier Typen von Empfehlungssystemen, die Nutzerinnen von Webseiten, Streamingdiensten oder Apps auf unterschiedliche Weisen mit anderen Nutzerinnen und Dingen (Filme, Songs, Artikel etc.) in Beziehung setzen. Popularitätsmetriken unterstellen eine pauschale Relevanz für alle; stereotypisierende Verfahren beruhen auf kategorialer Relationierung; inhaltsbasierte Verfahren und Collaborative Filtering relationieren Nutzerinnen und Dinge über Matchings, eine spezifische Variante des Vergleichs, die die paarweisen (Ähnlichkeits‑)Relationen von Nutzerinnen und Dingen vergleichen. In der digitalen Ökonomie dienen Empfehlungssysteme dazu, „good matches“ zwischen Unternehmen, Nutzerinnen, Dingen (und Dritten) zu generieren.

Published: May 2021

AbstractEarly intervention for children with reading impairments is crucial in order to achieve reading improvements and avoid school failure. One line of reading intervention research focuses on the experimental manipulation of reading rate through a text-fading training approach. Considering relevant reading-related predictors (i.e., orthographic knowledge and rapid automatized naming; RAN), we aim at evaluating the text-fading training’s efficiency for a sample of German reading-impaired third graders (n = 120). The purpose of the present study was to examine (1) the predictive value of orthographic knowledge and RAN and their contribution of explained variance in comprehension performance during training, (2) text-fading training effects on reading rate and comprehension in a pre-post comparison, and (3) (lasting) text-fading training effects at word and sentence level in a pre-post-follow-up design. Results of structural models indicated RAN to be significantly related to comprehension performance for the experimental group, whereas no sufficient regression weight was found for orthographic knowledge. A reverse pattern was found for the self-paced group. No significant improvements regarding reading rate and comprehension were revealed for the experimental group after training. However, significant positive effects on word and sentence level at post-test time point indicate stronger reading improvements for the experimental compared to the control group. The retention of training gains was indicated at sentence-level reading 6 months after the training. Possible explanations for the presented positive training effects as well as the mixed results for reading rate, comprehension, and follow-up preservation are discussed.

AbstractStaphylococcus aureus and coagulase-negative staphylococci are among the major causes of mastitis in sheep. The main goal of this research was to determine the in vitro antibacterial activity of several essential oils (EOs, n 30), then five of them were chosen and tested alone and in blends against staphylococci isolates. Five bacteria were isolated from episodes of ovine mastitis (two S. aureus and three S. xylosus). Biochemical and molecular methods were employed to identify the isolates and disk diffusion method was performed to determine their antimicrobial-resistance profile. The relative percentage of the main constituents in the tested essential oils and their blends was detected by GC-EIMS analysis. Antibacterial and bactericidal effectiveness of essential oils and blends were evaluated through minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). All of them showed sensitivity to the used antimicrobials. The EOs with the highest antibacterial activity were those belonging to the Lamiaceae family characterized by high concentrations of thymol, carvacrol and its precursor p-cymene, together with cinnamon EO, rich in cinnamaldehyde. In terms of both MIC and MBC values, the blend composed by Thymus capitatus EO 40%, Cinnamomum zeylanicum EO 20%, Thymus serpyllum EO 20% and Satureja montana EO 20% was found to be the most effective against all the isolates. Some essential oils appear to represent, at least in vitro, a valid tool against ovine mastitis pathogens. Some blends showed a remarkable effectiveness than the single oils, highlighting a synergistic effect in relation to the phytocomplex.

A new dynamic masking technique for time resolved PIV analysis
Authors: Lombardi Valentina , Rocca Michele La , Prestininzi Pietro 
Published: May 2021

Abstract
Time resolved PIV encompassing moving and/or deformable objects interfering with the light source requires the employment of dynamic masking (DM). A few DM techniques have been recently developed, mainly in microfluidics and multiphase flows fields. Most of them require ad-hoc design of the experimental setup, and may spoil the accuracy of the resulting PIV analysis. A new DM technique is here presented which envisages, along with a dedicated masking algorithm, the employment of fluorescent coating to allow for accurate tracking of the object. We show results from measurements obtained through a validated PIV setup demonstrating the need to include a DM step even for objects featuring limited displacements. We compare the proposed algorithm with both a no-masking and a static masking solution. In the framework of developing low cost, flexible and accurate PIV setups, the proposed algorithm is made available through a freeware application able to generate masks to be used by an existing, freeware PIV analysis package.

AbstractPreeclampsia (PE) is a serious complication of pregnancy. Exosomes are known to be upregulated in PE. In this study, we sought to investigate the effect of miR-486-5p from human placental microvascular endothelial cells, on the function of trophoblast cells. To investigate the function of human placental microvascular endothelial cell (HPVEC)-derived exosomes on trophoblast cells, HPVECs were treated with hypoxia/reoxygenation (H/R). The separation efficiency of exosomes was determined by transmission electron microscopy, nanosight and Western blot. Cell Counting Kit-8, EdU staining, wound-healing, and transwell assay were performed to detect the effect of exosomally transferred miR-486-5p inhibitor on proliferation, migration and invasion of trophoblast cells. MiRDB and dual-luciferase report assay were used to find the target of miR-486-5p. Our data revealed that miR-486-5p was significantly upregulated in H/R-treated HPVEC-Exo, and miR-486-5p was enriched in HPVEC-Exo. miR-486-5p inhibitor carried by HPVEC-Exo significantly inhibited the proliferation, migration and invasion of trophoblast cells. Insulin-like growth factor 1 (IGF1) was found to be the target of miR-486-5p, and IGF1 overexpression notably reversed the effect of miR-486-5p inhibitor from HPVEC-Exo on trophoblast cell function. In summary, H/R-treated HPVEC-derived exosomally expressing miR-486-5p inhibitor significantly inhibited the proliferation, migration and invasion of trophoblast cells via downregulation of IGF1. The findings from the present study may be useful in the development of treatments for PE.

Published: May 2021

AbstractIntegrated Pest Management (IPM) provides an illustration of how crop protection has (or has not) evolved over the past six decades. Throughout this period, IPM has endeavored to promote sustainable forms of agriculture, pursued sharp reductions in synthetic pesticide use, and thereby resolved myriad socio-economic, environmental, and human health challenges. Global pesticide use has, however, largely continued unabated, with negative implications for farmer livelihoods, biodiversity conservation, and the human right to food. In this review, we examine how IPM has developed over time and assess whether this concept remains suited to present-day challenges. We believe that despite many good intentions, hard realities need to be faced. 1) We identify the following major weaknesses: i) a multitude of IPM definitions that generate unnecessary confusion; ii) inconsistencies between IPM concepts, practice, and policies; iii) insufficient engagement of farmers in IPM technology development and frequent lack of basic understanding of its underlying ecological concepts. 2) By diverting from the fundamental IPM principles, integration of practices has proceeded along serendipitous routes, proven ineffective, and yielded unacceptable outcomes. 3) We show that in the majority of cases, chemical control still remains the basis of plant health programs. 4) Furthermore, IPM research is often lagging, tends to be misguided, and pays insufficient attention to ecology and to the ecological functioning of agroecosystems. 5) Since the 1960s, IPM rules have been twisted, its foundational concepts have degraded and its serious (farm-level) implementation has not advanced. To remedy this, we are proposing Agroecological Crop Protection as a concept that captures how agroecology can be optimally put to the service of crop protection. Agroecological Crop Protection constitutes an interdisciplinary scientific field that comprises an orderly strategy (and clear prioritization) of practices at the field, farm, and agricultural landscape level and a dimension of social and organizational ecology.

Published: May 2021

AbstractThe aim of this study was to review the existing literature on abdominal pain in children and adolescents with autism spectrum disorder. Systematic search of four databases (PsycINFO, ERIC, PubMed, MEDLINE) identified 13 studies that met the inclusion criteria. Articles were analyzed for common themes, including the prevalence of abdominal pain and gastrointestinal (GI) symptoms, associations between abdominal pain/GI symptoms and behavioral and emotional concerns, associations between abdominal pain/GI symptoms, and other comorbid disorders and treatment options based on gut bacteria, diet, and probiotics. Reasons for varying prevalence rates, persistence of symptoms over time, comorbidities, and different treatment options are discussed. Clinical implications and recommendations for future research are also discussed.
