Opis:
Composting is commonly used for waste management and the evaluation of its quality is important for successful application. Seed germination test is commonly adopted due to its capacity to examine the toxicity level of compost. The seed test is usually evaluated on the final product and the results can vary with the different methods and the type of seed utilized. In this study, the evolution of seed germination tests during the composting process of municipal waste (MSW) mixed with poultry manure (PM) of two species tomato and sugar beet was examined. The impact of compost water extracts on seed germination and plant primary root growth for each sampling was reported. The chemical parametrs were evaluated on the final product. Results show that mixture C1 with a higher amount of municipal waste gave less compost yield than mixture C2. After 35 days of composting, the compost was phytotoxic for tomato and sugar beet seeds. The seeds of the two cultures reacted differently to the same compost. The compost could stimulate sugar beet germination at days 110, 140, 180, 212 and 252. Seed germination of sugar beet was increased and delayed by one day by the compost stabilized and mature as compared with the control.

Opis:
Since the mid-2000s, the rising phenomenon of coworking spaces (CSs) has provided a flexible and mainly affordable solution for freelancers, entrepreneurs, small firms and start-ups, which may had experienced the issues of isolation when working from home, to work in a shared workplace, interact, socialize and share knowledge. This article explores the phenomenon of CSs within the theoretical framework of proximity measures a là Boschma (2005) – cognitive, organisational, social and institutional – that underpin the aspects of innovation, interaction and knowledge exchange. Though some studies on CSs have indirectly studied the different aspects of proximity, only a few of them focused on the importance of proximity measures at the workspace. With the aim to fill the gap in the literature, an empirical study was applied to Italy with 549 active CSs in 2018. The data was collected through an on-line questionnaire, addressed to a sample of 326 coworkers, focusing mainly on the set of questions devoted to understanding whether coworkers have exploited the proximity typologies in their CSs, have experienced increases in their revenues and well-being. The results are critically discussed, and some insights on policy implications are proposed.

Opis:
Utilization of drones is going to become predominated in cellular networks as aerial base stations in order to temporary cover areas where stationary base stations cannot serve the users. Detecting optimal location and efficient number of drone-Base Stations (DBSs) are the targets we tackle in this paper. Toward this goal, we first model the problem using mixed integer non-linear programming. The output of the proposed method is the number and the optimal location of DBSs in a two-dimension area, and the object is to maximize the number of covered users. In the second step, since the proposed method is not solvable using conventional methods, we use a proposed method to solve the optimization problem. Simulation results illustrate that the proposed method has achieved its goals.

Opis:
At the beginning of 2020, the world faced a new and unexpected challenge. Such a harmful situation has a potential to increase tensions in societies and create citizens’ distrust in their own governments and the European Union. In relation to these observations, the main hypothesis assumes that citizens’ trust in the Union decreased during the pandemic, compared to previous periods. Thus, the aim of the study is to identify the dynamics of trust in the EU in the member states. The research’s object is the citizens of the EU member states and the focus on dynamics in the levels of trust in 2016–2020, measured based on selected indicators. The data for analysis comes from the Eurobarometer. Statistical methods (frequencies and cross tables) and comparative approach are used for the analysis. On the macrolevel, it seemed that European leaders could do better, especially in the initial stages of the COVID-19 pandemic. However, the results of the Eurobarometer survey performed in the summer of 2020 show that average trust in the Union did not decreased. Тhe data shows that there is a variety across the countries, which was not presented in the current study. Thus, a further examination focused on the context in each of the countries is required, namely policies and measures stringency.
Na początku 2020 roku świat zetknął się z nowym i niespodziewanym wyzwaniem. Tak niesprzyjająca sytuacja ma potencjał zwiększenia napięć wśród społeczeństw i budowania sytuacji braku zaufania obywateli wobec własnych rządów i Unii Europejskiej. W odniesieniu do tych obserwacji główna hipoteza badawcza to założenie, że podczas pandemii zmniejszyło się zaufanie obywateli wobec państw członkowskich Unii Europejskiej w stosunku do lat poprzednich. W związku z tym celem badania jest identyfikacja dynamiki zmiany zaufania wobec Unii Europejskiej wśród jej państw członkowskich. Przedmiotem badania są obywatele Unii Europejskiej oraz skupienie na dynamice poziomu zaufania w latach 2016–2020 badane na podstawie wybranych wskaźników. Wykorzystane dane pochodzą z systemu Eurobarometr. Na potrzeby analizy posłużono się metodą analizy statystycznej (częstości i tablic krzyżowych) oraz porównawczej. Wydaje się, że na makropoziomie decydenci europejscy mogli sobie poradzić lepiej, zwłaszcza na wstępnych etapach wybuchu pandemii COVID-19. Wyniki ankiety przeprowadzonej przez Eurobarometr latem 2020 roku pokazują, że sytuacja różni się między państwami, czego jednak nie zaprezentowano w niniejszym badaniu. Z tego powodu potrzeba dalszych analiz skupionych na kontekście każdego państwa, tj. polityk szczegółowych i poziomu restrykcyjności wykorzystanych środków.

Opis:
In reference to cultural patterns in collectivistic societies, teaching and learning are greatly influenced by the teachers’ collectivistic or individualistic cultural orientation (Kaur & Noman, 2015). However, in dealing with both audiences and their teaching platforms, a chasm appears between methodologies and their applications since collectivistic societies are reluctant to accept methodologies perceived as mere Western innovations. In other words, a seemingly pedagogical incongruence arises where direct individualistic Western influence is perceived as unsuitable to a collectivistic mindset. One must keep in mind that family members in collectivist societies, who view themselves as part of a group rather than independent individuals, seem to feel more interdependent and mutually responsible for each other. In addition to Vygotski’s assertion that children’s cognitive development is enriched through social interaction with more skilled individuals (1978), Bandura (1982) emphasizes that the degree to which learners believe in their own self-efficacy influences their functioning cognitively, motivationally, emotionally, and their decision making process. Also, self-efficacy is perceived to accelerate the process of adapting to a new environment while learners adopt new cultural practices and consent to norms and expectations. In our exploration, second-language learners (SLLs) from collectivistic societies advance academically—English as a second language included—within the frame of sociocultural theory, since they seem to be motivated by their culturally- induced sense of obligation to honor their parents and other group members. These SLLs are positively influenced by their prior experiences with the group’s perceptions and expectations of their capability to learn an additional language (Bandura & Schunk, 1981; Schunk, 1991). Our research seems to indicate that this outcome is significantly affected by the self-efficacy and self-reliance produced by prior successes in challenging tasks that may have been mandated by the SLL’s elders. In addition, SLLs also seem to succeed in accomplishing more challenging goals as they observe their families’ values and traditions even when they are in a society that enforces individualistic values.

The presented study aimed at investigating the relationship between the extraversion level and speaking anxiety in the English as a Foreign Language (EFL) context on the one hand, and testifying the relationship between the extraversion degree and speech fluency and speech accuracy, on the other hand. To this end, 60 advanced university students, including 12 males and 48 females, participated in the study at the quantitative phase, and 28 of them, including 14 from the extraversion levels, and 14 from the introversion levels, were observed on their oral performance at the qualitative phase. Based on Spearman’s Rank Order Correlation using SPSS in the quantitative section, the findings revealed a strong negative correlation between the extraversion level and public speaking anxiety, on the one hand, and a strong positive correlation between the extraversion degree and speech fluency in the qualitative phase, on the other hand. Speech accuracy revealed having no significant correlation with the extraversion degree. Indeed, extraversion and introversion seem to be the major personality differences that have attracted the attention of psycholinguists, in particular Dornyei (2005); henceforth, it would be worth clarifying the underlying characteristics of this construct to gain a more comprehensive view of these personality type indicators, respectively.

Opis:
Introduction Factors such as prolonged sitting at work or improper posture of head during work may have a great role in neck pain occurrence among office employees, particularly among those who work with computers. Although some studies claim a significant difference in head posture between patients and pain-free participants, in literature the forward head posture (FHP) has not always been associated with neck pain. Since head, cervical and thoracic postures and their relation with neck pain has not been studied in Iranian office employees, the purpose of this study was to investigate the relationship between some work-related and individual factors, such as poor posture, with neck pain in the office employees. Material and methods It was a cross-sectional correlation study carried out to explore the relationship between neck pain and sagittal postures of cervical and thoracic spine among office employees in forward looking position and also in a working position. Forty-six subjects without neck pain and 55 with neck pain were examined using a photographic method. Thoracic and cervical postures were measured using the high thoracic (HT) and craniovertebral (CV) angles, respectively. Results High thoracic and CV angles were positively correlated with the presence of neck pain only in working position (p < 0.05). In forward looking position, there was no statistically significant difference between the 2 groups (p > 0.05). Conclusions Our findings have revealed that office employees had a defective posture while working and that the improper posture was more severe in the office employees who suffered from the neck pain.

Water deficit is one of the major environmental issues affecting biodiversity. Drought-related works are conducted to explore the mechanisms involved in drought vulnerability or resistance and to adopt the most advantageous tool to monitor these changes. Field spectroscopy, an accessory tool of remote sensing, evaluates the reflectance to collect continuous spectrum from materials. In the conducted study, the potential of using UV-Near infrared (NIR) spectroscopy as a non-destructive and reliable approach in monitoring of drought effects on three Medicinal and Aromatic Plants species (MAPs): Lavandula stoechas, Cistus laurifolius and Pistacia lentiscus from Northern Morocco during dry (July 2021) and wet (March 2022) period was addressed. It was found that Lavandula stoechas species is more impacted by water deficit than Cistus laurifolius and Pistacia lentiscus. Indeed, this species has a lower reflectance in Visible and NIR regions of the spectrum after a period of drought and therefore a higher vulnerability to water deficit than the other two species.

Opis:
Background. Periprosthetic distal femur fractures following total knee arthroplasty (PDFFTKA) are increasingly common [1], mainly in elderly patients with significant co-morbidities [2]. Surgical management usually requires balancing prompt fixation for early mobilization with the need to consider the least physiologically demanding option [3].The aim of this study was to assess predictors of clinical and radiological outcome in patients with PDFFTKA treated with open reduction and internal fixation (ORIF). Materials and methods. A retrospective cohort study of patients managed for PDFFTKA over the last 21 years in the Trauma & Orthopaedics Department of the Royal Shrewsbury Hospital (RSH) was carried out. Radiological images, pre- and post-operatively, were assessed for fracture related parameters. Last known functional status was evaluated using the most recent outpatient review letters. After assessment of normality of data, evaluation of predictors of clinical and radiological outcome was made using correlation analyses. Results. There was no statistically significant correlation between age, primary TKA to fracture interval, and length of intact medial cortex vs clinical outcome for the parametric variables evaluated. For non-parametric variables assessed, there was a statistically significant correlation between clinical outcome and evidence of callus formation (Spearman rho value -0.476; p=0.022). In stratifying the patients with ‘poor’ and ‘good’ outcome, there was no difference noted in primary TKA to fracture interval, or length of intact medial cortex (mm) between both groups. In terms of the number of comminuted fragments and anterior flange to fracture distance (mm), there was also no difference noted between the ‘poor’ and ‘good’ functional groups. Conclusions. 1. There was no observed correlation in pre-operative patient and fracture related variables with outcome in this population of patients with PDFFTKA. 2. Post-operative evidence of callus formation appears to be directly related to better clinical outcomes.

Opis:
The structural damages can lead to structural failure if they are not identified at early stages. Different methods for detecting and locating the damages in structures have been always appealing to designers in the field. Due to direct relation between the stiffness, natural frequency, and mode shapes in the structure, the modal parameters could be used for the purpose of detecting and locating the damages in structures. In the current study, a new damage indicator named “DLI” is proposed, using the mode shapes and their derivatives. A finite element model of a beam is used, and the numerical model is validated against experimental data. The proposed index is investigated for two beams with different support conditions and the results are compared with those of two well-known indices – MSEBI and CDF. To show the capability and accuracy of the proposed index, the damages with low severity at various locations of the structures containing the elements near the supports were investigated. The results under noisy conditions are investigated by considering 3% and 5% noise on modal data. The results show a high level of accuracy of the proposed index for identifying the location of the damaged elements in beams.

Opis:
Although customer satisfaction surveys are widely utilized by transit agencies, there are limited analyses in the literature on the perception of passengers as a result of service improvements. A before-after study can help to evaluate the effect of changes from customer’s points of view and thus guarantee a continuous improvement in the service. In this paper, customer satisfaction was directly observed through a Customer Satisfaction Survey (CSS) before and after certain changes. Furthermore, Structural Equation Modeling (SEM) is utilized to evaluate passenger’s perception of the service attribute importance. Finally, an Importance-Performance Analysis (IPA) is adapted to analyze the changes in satisfaction and importance from the passenger’s perspective on each service attribute. In both before and after cases, a consistent SEM structure is used. The follow-up IPA provides transit agencies with priorities to improve service attributes and helps managers to devote their resources to key attributes that matter to the riders. Metro line 3 in Tehran was selected as the case study which is 33.7 km long with 25 stations. Two surveys were performed one before (with the sample size of 300), and one after (with the sample size of 384) a set of changes the most important of which was a headway reduction. The SEM was developed with five latent variables of main service, comfort, information, protection, and physical appearance. This structure was assessed on both the before and after data collections and showed to be valid. Security at the station and security on board were the most important service attributes in both waves according to their factor loadings, while ethics and behavioral messages had the smallest factor loading and the least importance. Comparing the attributes in both surveys suggested that reducing the headway was effective, although it did not seem to be sufficient for enhancing the overall customer satisfaction and improvements need to be continued.
