‘I was really, really shocked’: A sociological exploration of the transition experiences of English Youth Academy male footballers from school to work

The world of football arguably brings together and unites people in support of their teams and countries, while inspiring young children and adolescents to dream of a professional career. Existing research in the field has sought to begin to understand what professional footballers experience on their journey through the game. However, much of this UK-based research has focused on first team players and their professional experiences, including transitions from youth team to first team and to retirement. This study, therefore, aimed to examine players during their youth academy scholarship at one English Championship club. This study focused on the transitional experiences of youth players from school to the academy and their resulting embodying of a footballer’s identity. Twelve semi-structured interviews with players aged 17–19, were conducted and then analysed by thematic analysis using figurational sociology concepts. Three different types of transition were identified. Among other reasons, early specialisation in football was a prevalent factor that partly influenced the way the players experienced their transition. The transition into the academy coincided with the transition from youth to adulthood that was arguably anything but linear as players managed the dominant sub-cultures present in the club.
Structural peculiarities, thermal and viscoelastic properties of ionomeric polyurethanes based on renewable raw materials

Abstract The creation of environmentally friendly polymeric materials able to decompose at the end of their service life under the environment, in particular, by replacing the original nonrenewable components with natural ones, is a promising way to decrease the impact of polymer wastes on the environment. The article examines the effect of natural components (castor and palm vegetable oils, xanthan exopolysaccharide), the mass fraction of which amounts to 70 wt. % on the structure, thermal and viscoelastic properties of water-based polyurethanes. The structure - properties relationship was confirmed by wide and small-angle X-rays scattering, DMA, TGA and DSC analysis. The presence of components of natural origin have been shown to affect the structure, viscoelastic behavior and thermal properties of studied polyurethanes. The data obtained made it possible to conclude the possibility of obtaining stable polyurethanes with an adjustable set of properties depending on the amount and nature of the renewable raw materials.
Impulse buying in hospitality: The role of content posted by social media influencers

In previous research, the significance of Social Media Influencers (SMIs) on the entire tourism industry has been indicated. In this article, it is explored how arousal and thematic compatibility in the presentation of a hotel facility’s offer by a SMI determines purchase intention and the urge to buy impulsively. To carry out this objective, a laboratory experiment was conducted with graphic stimuli and controlling arousal using neurophysiological data. The obtained results are relevant within the context of promotion methods in social media, maximising the effect of cooperation with SMIs. Managerial and theoretical implications of the findings are discussed.
Real-time multi-window stereo matching algorithm with fuzzy logic

Stereo matching obtains a depth map called a disparity map that indicates or shows the positions of the objects in a scene. To estimate a disparity map, the most popular trend consists of comparing two images (left ‐ right) from two different points from the same scene. Unfortunately, small window sizes are suitable to preserve the edges, while large window sizes are required in homogeneous areas. To solve this problem, in this article, a novel real ‐ time stereo matching algorithm embedded in an FPGA is proposed. The approach consists of estimating disparity maps with different window sizes by using the sum of absolute differences (SAD) as a local correlation metric. Once the disparity maps are obtained, the left ‐ right consistency for each window size is computed. At the end of this stage, the centre pixel deviation is estimated through a 5 � 5 window and the Sobel gradient is extracted from the left image. Finally, both parameters are processed by a Fuzzy Inference System (FIS), which combines the calculated disparities and generates a final disparity map. An architecture embedded in FPGA is established and hardware acceleration strategies are discussed. Experimental results demonstrated that this algorithmic formulation provides promising results compared with the current state of the art.
A Structural Study of 0.06LiNbO3-0.94K0.5Na0.5NbO3 from Neutron Total Scattering Analysis

The structure of ferroelectric 0.06LiNbO3-0.94K0. 5Na0.5NbO3 (KNNL6) was investigated by the neutron total scattering method in the temperature range of 290–773 K. The Rietveld analysis using the powder neutron diffraction data in the range of 290–773 K indicates transition from a two-phase (monoclinic and tetragonal) mixture at room temperature to tetragonal and cubic phases at higher temperatures. However, characterization of the local structure by the pair distribution function (PDF) method indicates that the local structure (r ≲ 10 Å) stays monoclinic over the same temperature range. Besides, the local oxygen octahedral distortion exhibits smaller changes with temperature than what is observed for the long-range average structure.
Living a Calling and Work–Family Interface: A Latent Profile Analysis

The positive outcomes of calling have been examined in a large and growing number of studies, yet little is known about how calling relates to the work-family interface. In this study, we adopted a person-centered approach using latent profile analysis to explore how living a calling relates to different work-family interface profiles. With a sample of 267 Chinese university counselors, we found three work-family interface profiles: slightly conflictual (51%), experiencing slightly higher than average levels of work-to-family conflict (WFC) and family-to-work conflict (FWC) and slightly lower than average levels of work-to-family enrichment (WFE) and family-to-work enrichment (FWE); work-to-family conflictual (15%), with higher levels of WFC and lower levels of FWC, WFE, and FWE; and enriched (34%), indicated by higher levels of WFE and FWE and lower levels of WFC and FWC. The results revealed that the greater the extent to which participants were living their calling, the more likely they were to be classified into the enriched profile. Our findings contribute to the literature on calling by offering person-centered insights on the relation between calling and the work-family interface.
First year university students’ perception of autonomy: an individualistic approach

ABSTRACT Autonomy has been considered both as a precondition and a crucial learning outcome of higher education. Recent research has been focusing on measuring university students’ autonomy or its development. However, whether and how students’ autonomy can be measured quantitatively is still debatable. Although autonomy is known as a changing process and varies among individuals, it is agreed that students’ learning behaviours are largely affected by their perceptions; very few studies, however, have examined students’ own perception of autonomy. This study, therefore, adopts a longitudinal qualitative approach to investigate the changes in students’ own perceptions of autonomy over five different times during their first-year study in a Hong Kong University, and examine the relationship between the perceptions and behaviours of their autonomy. Using in-depth semi-structured interviews with eight first-year students, the study found that although the participants held some common understanding of autonomy, they also demonstrated various interpretations of this concept. They also had a slightly different focus on different dimensions of autonomy, which were affected by their own individual experiences. An individualistic approach is therefore proposed to understand students’ development of autonomy.
Effects of Roll Vortices on the Evolution of Hurricane Harvey During Landfall

Horizontal boundary layer roll vortices are a series of large-scale turbulent eddies that prevail in a hurricane’s boundary layer. In this paper, a one-way nested sub-kilometer-scale large eddy simulation (LES) based on the Weather Research and Forecasting model (WRF) was used to examine the impact of roll vortices on the evolution of Hurricane Harvey around its landfall from 0000z on 25 to 1800z 27 August 2017. The simulation results imply that the turbulence in the LES can be attributed mainly to roll vortices. With the representation of roll vortices, the LES simulation provided a better simulation of hurricane wind vertical structure and precipitation. In contrast, the mesoscale simulation with the YSU PBL scheme overestimated the precipitation for the hurricane over the ocean.Further analysis indicates that the roll vortices introduced a positive vertical flux and thinner inflow layer, whereas a negative flux maintained the maximum tangential wind at around 400 m above ground. During hurricane landfall, the weak negative flux maintained the higher wind in the LES simulation. The overestimated low-level vertical flux in the mesoscale simulation with the YSU scheme led to overestimated hurricane intensity over the ocean and accelerated the decay of the hurricane during landfall. Rainfall analysis reveals that the roll vortices led to a weak updraft and insufficient water vapor supply in the LES. For the simulation with the YSU scheme, the strong updraft combined with surplus water vapor eventually led to unrealistic heavy rainfall for the hurricane over the ocean.
Research on Regularities of Cyclic Air Motion through a Respirator Filter

In this paper, a solution to the problem of the change in the pressure drop in a respirator filter during cyclic air motion is suggested since the current theory of filtering is based on steady-flow processes. The theoretical dependence of the pressure drop in the respirator filter on air flow rate is determined, which is represented by the harmonic law, which characterizes the human respiration process during physical work. For the calculation, a filter model was used, which is represented by a system of parallel isolated cylinders with a length equal to the total length of the filter fibres surrounded by porous shells formed by a viscous air flow field, with a size determined by the equal velocities of the radial component of air flow and undisturbed flows. The flow-around process in the proposed model of air flow through the respirator filter is described by the Brinkman equation, which served to establish the total air flow resistance in the proposed system under conditions of velocity proportionality. It consists of two parts: the first characterizes the frictional resistance of the air flow against the surface of the cylinder, which imitates the filter fibre; the second—the inertial part—characterizes the frequency of pulsations of respiratory movements during physical performance. The divergence of the analytical results and experimental studies is no more than 20%, which allows the use of the established dependence to estimate the change in pressure drop in a respirator filter made of filter material “Elephlen” when the user carries out different physical activities. This allows the period of effective protective action of respirators with different cycles of respiration during physical activities to be specified, which is a very serious problem that is not currently regulated in health and safety regulations, and it also allows the prediction of the protective action of filters and respiratory protection in general.
A Sum of Its Parts: Party Fit and Party Change in the U.S. House

Previous research has noted the transformation of the American parties since the 1970s, as exhibited in their increased ideological polarization and transformation on social issues like civil rights, abortion, and the environment. We contribute to the literature on party change by theoretically stressing the decentralized and individualistic nature of American parties, while using a measure of party change that is based on legislative behavior beyond roll call voting. Our paper uses social network analysis to analyze the parties from the 93rd to 110th Congresses, utilizing bill cosponsorship to define connections between members. Our analysis illustrates how the core of the party, that is, who are most central in the cosponsorship network, has changed over time. We find evidence that party centrality influenced retirement decisions, thereby reinforcing and contributing to party change.
The Effect of Reciprocity on Mobile Wallet Intention: A Study of Filipino Consumers

The authors build on the literature on reciprocity by exploring a prevalent social and economic phenomenon in the Philippines where individuals with positive mobile phone balances can SMS loads to acquaintances. This practice is known as “pasaload”—an abbreviation of Pass-A-Load. The research was designed based on the literature review that in turn resulted in a research model that focused on six constructs: reciprocity, loyalty, habit, switching costs, trust, and future repurchase. Hypotheses were developed as the basis for a scaled survey of 1050 Philippine smartphone users, with the questions adapted from but adhering closely to the original questions from appropriate articles in the literature review. Overall the mediating effects from the two models are consistent with the expectations from the literature and analysis. In the Philippine context, habit might be a strong mediator even if the true financial and convenience costs to switch is low.
Migration and Redistribution of Sulfur Species during Chemical Looping Combustion of Coal with CuFe2O4 Combined Oxygen Carrier

Chemical looping combustion (CLC) by direct use of coal as fuel has gained great recognition for the great advantage for CO2 capture, but sulfur occurrence and evolution in the CLC system is always a great concern. In order to gain a comprehensive insight into the migration and redistribution of various sulfur species in the CLC system, a typical Chinese coal (designated as LZ) with large size range around 180–400 μm (as frequently used in the real CLC system) was selected and its reaction with CuFe2O4 combined oxygen carrier (OC) was investigated using thermogravimetric analysis (TGA), which indicated that the reaction behavior of CuFe2O4 with LZ coal of large size changed greatly due to the maceral enrichment and mineral segregation in the LZ coal. At the two main reaction stages, the characteristic temperatures of CuFe2O4 reaction with LZ coal of large size range shifted to higher temperatures and the reaction rates increased relative to the reaction of CuFe2O4 with LZ coal of small size range (63–106 .
Standardization can be good for exploration: a social capital view of the productivity dilemma in operational teams

Abstract Process Management Programs (PMPs) rely heavily on the standardization of activities to improve organizational efficiency and reliability. Standardization, however, can lead to rigidity and inertia, which may eventually inhibit exploration and innovation. While scholars have provided cognitive and routine-based arguments to cope with this dilemma, the fact that standardization is a social process that requires collaboration between individuals has been overlooked. In this paper, we propose that standardization can improve a team’s social capital and thereby facilitate the activities that enable exploration. Specifically, we hypothesize that standardization relates positively to external communication, psychological safety, and the perception of support for innovation in operational teams. These three social capital attributes mediate the relationship between standardization and exploration. We tested this multilevel mediation model by analysing 431 members of 62 operational teams in a large multinational mining company that had recently implemented a Process Management Program (Lean Management). Our multilevel mediation results confirmed that standardisation promoted exploration by enhancing the teams’ social capital. For robustness we tested our model with a second survey of 450 workers of different companies and obtained similar results. Therefore, we propose that the productivity dilemma can be balanced by improving operational teams’ social capital.
Absolute ion density measurements in the afterglow of a radiofrequency atmospheric pressure plasma jet

Atmospheric pressure plasma jets (APPJs) can enable large fluxes of reactive species impinging on treated substrates in many applications. The relative importance of ionic versus neutral reactive species fluxes produced by APPJs is to date mainly deduced from modeling due to the challenge of measuring absolute ion densities/fluxes. In this study, a calibration was performed to determine the absolute densities of cold ions in the afterglow region of an radiofrequency-driven APPJ in Ar + 1% O2 by molecular beam mass spectrometry. Positive ion densities were found to be about 3–4 orders of magnitudes lower than the densities of the dominant reactive neutral species (O, O2(a 1Δg), O3) in the afterglow region of the APPJ at a distance larger than 2 mm from the visible plasma plume. The results illustrate the ability of molecular beam mass spectrometry to enable a quantitative evaluation of both neutral and ionic species in many applications using APPJs.
Evaluating the communication within fire and rescue services and the NHS on the fire risk of emollients in accordance of the MHRA safety update

The Medicines and Healthcare products Regulatory Agency update in 2018 reported 50 fatal fires linked with emollient use. It detailed the fire risk and new advice aimed at fire service and health care professionals in reporting of such fire incidents and educating the public on safer use of emollients. This study investigates how this has been communicated internally and publicly, with 52 Fire and Rescue Services (FRSs) websites and, 191 Clinical Commissioning Groups (CCGs), and 21 Local Health Boards (LHBs) formularies accessed. A Freedom of Information Request (FOIR) was also made, giving further details of implementations. Our study revealed that 63% of FRSs, 32% of CCGs and, 72% of LHBs gave no safety advice within their website or formularies. Of the 37% of FRSs and 68% of CCGs that did, only 5% and 4% were sufficiently up to date. 27% of FRSs and 28% of CCGs/LHBs revealed that they had no warning/advice internally in their FOIR responses and 25% of FRSs and, 35% of CCG/LHBs had not disseminated advice on using emollient safely to the public. We suggest improvements in safety campaigns using a multiagency and national approach and recommend organizations to educate professionals to improve reporting and effective dissemination.
Sustained Oxygen Spectral Gaps and Their Dynamic Evolution in the Inner Magnetosphere

Van Allen Probes observations of ion spectra often show a sustained gap within a very narrow energy range throughout the full orbit. To understand their formation mechanism, we statistically investigate the characteristics of the narrow gaps for oxygen ions and find that they are most frequently observed near the noon sector with a peak occurrence rate of over 30%. The magnetic moment (μ) of the oxygen ions in the gap shows a strong dependence on magnetic local time (MLT), with higher and lower μ values in the morning and afternoon sectors, respectively. Moreover, we find through superposed epoch analysis that the gap formation also depends on geomagnetic conditions. Those gaps formed at lower magnetic moments (μ < 3,000 keV/G) are associated with stable convection electric fields, which enable magnetospheric ions to follow a steady drift pattern that facilitates the gap formation by corotational drift resonance. On the other hand, gaps with higher μ values are statistically preceded by a gradual increase of geomagnetic activity. We suggest that ions within the gap were originally located inside the Alfven layer following closed drift paths, before they were transitioned into open drift paths as the convection electric field was enhanced. The sunward drift of these ions, with very low fluxes, forms a drainage void in the dayside magnetosphere manifested as the sustained gap in the oxygen spectrum. This scenario is supported by particle‐tracing simulations, which reproduce most of the observed characteristics and therefore provide new insights into inner magnetospheric dynamics.
Phenolic Composition and Antioxidant Properties of Rhododendron ponticum: Traditional Nectar Source for Mad Honey

Abstract Relying on nectar of the Rhododendron plant species, honeybees produce mad honey which is marketed relatively at high cost due to its enormous medical uses. Herein, Rhododendron ponticum was chemically characterized regarding total phenolics, antioxidant properties and profile of phenolic compounds to present authentic data of the major source of Mad honey. To distinguish, flowers of the plant were divided into two parts, corolla and calyx. Antioxidant activity of the extracts was examined by two different methods; scavenging of free radical of ABTS and DPPH. For the first time 9 phenolic acids and 3 flavonoids are found from this species on high performance liquid chromatography (HPLC). In comparaison with leaves, methanolic extract of flowers showed the highest total phenolic contents as Gallic Acid Equivalent (349.53±0.346 mg/100 g), total flavonoid contents as Quercetin Equivalent (311.16±1.669 mg/100 g) as well as antioxidant activity with IC50 of 1.23, 1.30 mg/mL in DPPH and ABTS assays.
Efficiency of biotransformation of shellfish waste to carotenoprotein by autolysis and crab-shrimp endo-enzymes

ABSTRACT The present study reports a simple, green methodology for the recovery of carotenoproteins from shellfish waste with the aim of using in aquafeed. Seven (07) treatment samples with shrimp:crab ratios of 100:00, 95:05, 90:10, 80:20, 60:20, 40:20 and 20:20 were prepared. A 100% crab sample was used as the reference sample. All samples were autolyzed at 55°C for 20 minutes and carotenoprotein, crude protein, and astaxanthin yields in the dried filtrate were determined. The recovery efficiency of carotenoprotein yield had no significant difference among treatments. Shrimp: crab ratio of 90:10 recorded the highest crude protein recovery efficiency (174%) which was significantly higher than that of all other treatments. The recovery efficiency of astaxanthin was highest (160%) in 40:20 shrimp:crab treatment. The lowest crude protein and astaxanthin content were recorded in 100% crab sample. SDS PAGE of carotenoproteins shows the presence of small peptide fragments less than 44 kDa in most treatments and absence of visible peptide fragments in shrimp: crab ratios of 100:00. 90:10 and 20:20. Results reveal that shrimp: crab ratio determines the recovery efficiency of carotenoprotein, crude protein, and astaxanthin, and the collective effect of shrimp-crab endo-enzymes and autolysis not only increased the recovery efficiencies but also the smaller peptides important in fish nutrition.
