Brand-Image Communication Through Social Media: The Case of European Professional Football Clubs

Social-media platforms have become an important tool for sport marketers to communicate their brand image and engage with fans. This study analyzed 1,115 Facebook posts and 16,308 tweets from 10 of the most valuable European professional football clubs to identify the range of brand associations communicated and the level of online fan engagement. Statistical analysis captured correlations between and among selected brand attributes, time periods of posts (in and off-season), and levels of fan engagement. On both Facebook and Twitter, football clubs posted more frequently during the season, while content associated with product-related attributes was the focus of such communication. Product-related content was found to generate higher levels of online fan engagement. The study extends the literature on sport teams’ brand management through social media and offers practical recommendations on how to enhance fan identification and engagement and ultimately make financial and reputational gains.
Co-creation and co-destruction: A practice-theory based study of interactive value formation

Drawing on an empirical study of public transport, this paper studies interactive value formation at the provider—customer interface, from a practice—theory perspective. In contrast to the bulk of previous research, it argues that interactive value formation is not only associated with value co-creation but also with value co-destruction. In addition, the paper also identifies five interaction value practices — informing, greeting, delivering, charging, and helping — and theorizes how interactive value formation takes place as well as how value is intersubjectively assessed by actors at the provider—customer interface. Furthermore, the paper also distinguishes between four types of interactive value formation praxis corresponding with four subject positions which practitioners step into when engaging in interactive value formation.
Structure and dynamics of the planktonic diatom community in the Iguassu River , Paraná State , Brazil

The evaluation of abiotic and biotic variables can provide information for understanding the structure and function of lotic systems. To obtain this information, measurements of 15 chemical and physical variables and of phytoplankton were conducted at two sampling stations. The present study aims to evaluate the temporal and spatial variation of planktonic diatoms in terms of abiotic variables and the trophic level of the river water and to select diatom species as descriptors of the physical and chemical conditions of the water upstream (S1) and downstream (S2) of the Iguassu River over an annual cycle. Sampling station S1 was classified as oligotrophic to mesotrophic, and S2 was classified as ultra-oligotrophic to oligotrophic. A total of 98 diatom species distributed among 39 genera was recorded, showing no dominant species but 36 abundant species. Although the differences of chemical and physical variables between S1 and S2 were limited to greater turbulence and turbidity, processes triggered by heavy rainfall exerted a significant influence on community structure, and a temporal change in composition was observed. At the end of the dry period, due to the recovery of nutrients and high transparency, there was an abundance of Cocconeis placentula var. lineata. In the rainy period, with increased turbulence and turbidity processes resulting from higher rainfall, there was an abundance of Aulacoseira granulata var. granulata.
Comparative Evaluation of Shear Bond Strength of Three Different Luting Cements toward Ceramic and Dentin for All Ceramic Restorations : An in vitro Study

All ceramic restorations benefit from resin cement bonding to the tooth. No currently available luting agent is ideal for all situations. The comparison of the bonding ability of different luting cements to ceramic and dentin is thus deemed necessary. The purpose of this study was to evaluate the shear bond strength of different luting cements to both ceramic and dentin and then to evaluate the mode of bond failure by scanning electron microscopy.
Predictors of clinical recovery from concussion: a systematic review

Objective A systematic review of factors that might be associated with, or influence, clinical recovery from sport-related concussion. Clinical recovery was defined functionally as a return to normal activities, including school and sports, following injury. Design Systematic review. Data sources PubMed, PsycINFO, MEDLINE, CINAHL, Cochrane Library, EMBASE, SPORTDiscus, Scopus and Web of Science. Eligibility criteria for selecting studies Studies published by June of 2016 that addressed clinical recovery from concussion. Results A total of 7617 articles were identified using the search strategy, and 101 articles were included. There are major methodological differences across the studies. Many different clinical outcomes were measured, such as symptoms, cognition, balance, return to school and return to sports, although symptom outcomes were the most frequently measured. The most consistent predictor of slower recovery from concussion is the severity of a person’s acute and subacute symptoms. The development of subacute problems with headaches or depression is likely a risk factor for persistent symptoms lasting greater than a month. Those with a preinjury history of mental health problems appear to be at greater risk for having persistent symptoms. Those with attention deficit hyperactivity disorder (ADHD) or learning disabilities do not appear to be at substantially greater risk. There is some evidence that the teenage years, particularly high school, might be the most vulnerable time period for having persistent symptoms—with greater risk for girls than boys. Conclusion The literature on clinical recovery from sport-related concussion has grown dramatically, is mostly mixed, but some factors have emerged as being related to outcome.
The Move toward Dynamic Governance in Indonesian Public Service (Case Study of the Dynamic capabilities of the Immigration Office Class I Surabaya Regions, in Pasport Service)

This paper aims to examine the dynamic capabilities of public institution, in order to improve the quality of public services in Indonesia. It is based on a research on the capability of the Immigration Office Class I, Surabaya region in the perspective of dynamic governance; and the factors that drive such dinamic capability especially in imigration’s core service, namely, passport services. The dynamic capabilities are examined through three criteria namely, thinking ahead, thinking again, and thinking across. Qualitative research method was employed in this research, involving interview, observation, and document analysis. A total of 31 informants were interviewed in this research. The informants were chosen with purposive and snowball sampling, taken from the officers of the imigration office and its affiliation partners for pasport services (i.e. staf from Post Office and mass media). This research finds that overal, the Immigration Office Class I Surabaya Regions has move towards dynamic capabilities, and thus dynamic governance. Such movement was driven by the influence of strong leadership roles, supported by the use of information technilogy. As this research highlights, the strong leadership role has, in turn, created more motivated, and innovative staff (or followers) that eager to innitiate change or create various innovations. This is also the realisation of thinking ahead criteria. Moreover, the leadership roles has intensified service performance evaluation in the imigration office, and later make the evaluation not only becoming more routine, but also impacted on the changes of various service policies. This is the realisation of thinking again. Finally, this research has observed the realisation of thinking across mindset, shown by the staff’s attitude towards their eagerness to learn (or ‘the will to learn’) from others and doing comparative study or sight visit to other immigration office across areas in Indonesia. Ultimately, this research has shed a light to the more fact that Indonesian bureaucracy and institution has move towards dynamic capablities, and thus, may advance the global competitiveness of Indonesia’s public service.
Evaluating Goals in Worker Health Protection Using a Participatory Design and an Evaluation Checklist

Spanish-speaking immigrant workers in construction are considered hard to reach and at high risk for work-related injury and fatality. This evaluation study describes the use of participatory methods and an evaluation checklist to consider a health and safety (H&S) training program for these workers. A previously developed training manual and model were disseminated to eight worker centers (WCs) through participatory research collaboration. It incorporated H&S training for workers while strengthening the role of WCs as sources for leadership development and worker empowerment. Design, delivery, reaction, application, and extension were assessed through individual interviews with participants, trained trainers, and center staff and through observation of training sessions and partner debriefs; pre- and post-training tests assessed participant learning. Results indicate moderate learning and application by participants and strong evidence for structural gains in and among WCs. We conclude that such partnerships and models are valuable tools for collaborating with hard-to-reach workers.
Comparison of conventional and collapsed region operation of capacitive micromachined ultrasonic transducers

We report experimental results from a comparative study on collapsed region and conventional region operation of capacitive micromachined ultrasonic transducers (CMUTs) fabricated with a wafer bonding technique. Using ultrasonic pulse-echo and pitch-catch measurements, we characterized single elements of 1-D CMUT arrays operating in oil. The experimental results from this study agreed with the simulation results: a CMUT operating in the collapsed region produced a higher maximum output pressure than a CMUT operated in the conventional region at 90% of its collapse voltage (3 kPa/V vs. 16.1 kPa/V at 2.3 MHz). While the pulse-echo fractional bandwidth (126%) was higher in the collapsed region operation than in the conventional operation (117%), the pulse-echo amplitude in collapsed region operation was 11 dB higher than in conventional region operation. Furthermore, within the range of tested bias voltages, the output pressure monotonously increased with increased bias during collapsed region operation. It was also found that in the conventional mode, short AC pulses (larger than the collapse voltage) could be applied without collapsing the membranes. Finally, while no significant difference was observed in reflectivity of the CMUT face between the two regions of operation, hysteretic behavior of the devices was identified in the collapsed region operation
The Combined Use of Chemical, Organic Fertilizers and/or Biofertilizer for Crop Growth and Soil Fertility

Plant nutrients are essential for production of crop and healthy food for the word's expanding population. Plant nutrients are therefore a vital component of sustainable agriculture. Increased crop production largely relics on the type of fertilizers used to supplement essential nutrients for plants. The nature and the characteristics of nutrients release of chemical, organic and biofertilizers are different, and each type of fertilizer has its advantages and disadvantages for crop growth and soil fertility. A sound management of fertilization must attempt to ensure both enhanced and safeguard the environment; therefore, a balanced fertilization strategy that combines use of chemical, organic and /or biofertilizers must to be developed and evaluated.
Bone densitometry in clinical practice.

Summary points Osteoporosis is a major health problem in the elderly population. It causes more than 150000 fractures each year in the United Kingdom with an estimated cost of pounds sterling742 million Bone mass is a major determinant of risk of fracture and can be assessed by non-invasive techniques such as dual energy x ray absorptiometry Densitometric criteria based on standard deviation scores expressed in relation to reference values in premenopausal women (T scores) provide diagnostic categories from which thresholds for prevention and treatment can be defined on the basis of risk of fracture Population based screening for low bone mass in perimenopausal women cannot at present be justified. In clinical practice, however, bone densitometry has an important role in the diagnosis of osteoporosis in high risk groups and in the monitoring of treatment in some patients For these indications, it is estimated that about 175 bone scans per 100000 population would be needed annually, requiring an annual expenditure for the average health district of pounds sterling25200 At present, bone densitometry resources in the United Kingdom are inadequate to meet these needs. There is an urgent need to improve existing facilities so that effective strategies for the prevention and treatment of osteoporosis in clinical practice can be implemented
First Snapshots of the HIV-1 RNA Structure in Infected Cells and in Virions*

With the increasing interest of RNAs in regulating a range of cell biological processes, very little is known about the structure of RNAs in tissue culture cells. We focused on the 5′-untranslated region of the human immunodeficiency virus type 1 RNA genome, a highly conserved RNA region, which contains structural domains that regulate key steps in the viral replication cycle. Up until now, structural information only came from in vitro studies. Here, we developed chemical modification assays to test nucleotide accessibility directly in infected cells and viral particles, thus circumventing possible biases and artifacts linked to in vitro assays. The secondary structure of the 5′-untranslated region in infected cells points to the existence of the various stem-loop motifs associated to distinct functions, proposed from in vitro probing, mutagenesis, and phylogeny. However, compared with in vitro data, subtle differences were observed in the dimerization initiation site hairpin, and none of the proposed long range interactions were observed between the functional domains. Moreover, no global RNA rearrangement was observed; structural differences between infected cells and viral particles were limited to the primer binding site, which became protected against chemical modification upon tRNA3 Lys annealing in virions and to the main packaging signal. In addition, our data suggested that the genomic RNA could already dimerize in the cytoplasm of infected cells. Taken together, our results provided the first analysis of the dynamic of RNA structure of the human immunodeficiency virus type 1 RNA genome during virus assembly ex vivo.
Heterofunctional nanosheet controlling cell adhesion properties by collagen coating

Recently, biomaterials have been widely used in a variety of medical applications. We previously reported that a poly-l-lactic acid (PLLA) nanosheet shows anti-adhesive properties and constitutes a useful biomaterial for preventing unwanted wound adhesion in surgical operations. In this article, we examine whether the PLLA nanosheet can be specifically modified with biomacromolecules on one surface only. Such an approach would endow each side of the nanosheet with discrete functions, that is anti-adhesive and pro-healing properties. We fabricated two distinct PLLA nanosheets: (i) collagen cast on the surface of a PLLA nanosheet (Col-Cast-PLLA) and (ii) collagen spin-coated on the nanosheet (Col-Spin-PLLA). In the Col-Spin-PLLA nanosheet, the collagen layer had a thickness of 5–10 nm on the PLLA surface and displayed increased hydrophilicity compared to both PLLA and Col-Cast-PLLA nanosheets. In addition, atomic force microscopy showed disorganized collagen fibril formation on the PLLA layer when covered using the spin-coating method, while apparent bundle formations of collagen were formed in the Col-Cast-PLLA nanosheet. The Col-Spin-PLLA nanosheet provided a microenvironment for cells to adhere and spread. By contrast, the Col-Cast-PLLA nanosheet displayed reduced cell adhesion compared to the Col-Spin-PLLA nanosheet. Consistent with these findings, immunocytochemical analysis clearly showed fine networks of actin filaments in cells cultured on the Col-Spin-PLLA, but not the Col-Cast-PLLA nanosheet. Therefore, the Col-Spin-PLLA nanosheet was shown to be more suitable for acting as a scaffold. In conclusion, we have succeeded in developing a heterofunctional nanosheet comprising a collagen modified side, which has the ability to rapidly adhere cells, and an unmodified side, which acts as an adhesion barrier, by using a spin-coating technique.
Magnetic Resonance Enterography for Suspected Inflammatory Bowel Disease in a Pediatric Population

Objectives: The aim of the study was to determine the accuracy of magnetic resonance enterography (MRE) in diagnosing and differentiating pediatric inflammatory bowel disease (IBD). The secondary aims were to determine the accuracy of MRE in grading disease activity and determine the interobserver agreement for individual MRE parameters. Patients and Methods: Pediatric patients scheduled to undergo esophagogastroduodenoscopy, ileocolonoscopy with biopsies, and barium enteroclysis for suspected IBD were included and underwent MRE. MRE images were evaluated by 3 observers. The accuracy of MRE was calculated using the clinical diagnosis based on endoscopic, histopathological, and barium enteroclysis examinations as reference standard. Results: Thirty-three patients were available for analysis. IBD was correctly diagnosed in, respectively, 61%, 61%, and 91% of the patients by the 3 observers, with a specificity of 80%, 90%, and 60%. Differentiation between Crohn disease (CD) and ulcerative colitis (UC) was accurately done in, respectively, 67%, 53%, and 80% of patients with CD and 0%, 14%, and 43% of patients with UC. Disease activity was understaged on MRE in the majority of patients. Intraclass correlation coefficients for measurements of bowel thickness were 0.52 (observer 1–2; observer 1–3) and 0.34 (observer 2–3). Interobserver agreement on bowel wall enhancement and stenosis was moderate to good (κ 0.59, 0.56, and 0.56 and κ 0.62, 0.32, 0.30, respectively). Conclusions: Sensitivity and specificity values of MRE for diagnosing pediatric IBD were moderate to good. CD, but not UC, was accurately diagnosed by MRE in a large proportion of patients. Activity was understaged in a large proportion of patients. Interobserver agreement for individual MRE parameters was fair to good.
MRIG frequency mismatch and quadrature control

The output variables of an MRIG (Microscale Rate Integrating Gyroscope), x, y, satisfy the equations of motion of a two-dimensional oscillator. (Ref. [1]) To examine the role of a mismatch of the two principal frequencies, ω<sub>1</sub> and ω <sub>2</sub>, we look at the response to a constant rate input, Ω, for times short compared to the damping time constants. Eqs. (7) of Ref. [1], when specialized to principal-axis coordinates, reduce to x - 2kΩy + ω<sup>2</sup><sub>2</sub> x = 0 (1) ÿ + 2kΩx + ω<sup>2</sup><sub>1</sub> y = 0 when the damping and external-force terms are omitted. k is the angular gain factor. The solution for x(t), y(t) in terms of the initial values x(0), y(0), x(0), y(0) is readily obtained using Laplace transforms. To reduce the writing, we introduce the definitions (Eq. (8) of Ref. [1]).
Expression of Glucose Transporters in Rat Brain Following Transient Focal Ischemic Injury

Abstract: We have investigated the serial changes in the transcription and translation of the rat glucose transporter (GLUT) 1 and 3 genes after 3 h of middle cerebral artery (MCA) occlusion followed by reperfusion. Northern blot analysis and in situ hybridization study were performed to determine the chronological change and regional expression. In the ipsilateral anterior cerebral artery (ACA) cortex, GLUT1 mRNA expression was increased at 12 h (11.6‐fold) of reperfusion, and its expression was detected not only in vascular endothelial cells but also in neurons. At 48 h of reperfusion, GLUT3 mRNA expression was increased in the ipsilateral ACA (8.6‐fold) and in the contralateral MCA cortex (9.1‐fold). Immunohistochemical study failed to show GLUT1 protein synthesis in neurons in the ipsilateral ACA cortex. The immunoreactivity of GLUT3 protein was increased in neurons in ipsilateral ACA cortex and contralateral MCA cortex. Our results suggest that the expression of GLUT1 and GLUT3 is controlled differently after transient focal ischemic conditions. Furthermore, the postischemic localizations of both GLUT1 and GLUT3 expressions may be altered from the normal physiological expression pattern, which may be of importance in investigating postischemic cell function.
Fluoride concentrations in a range of ready-to-drink beverages consumed in Heilongjiang Province, north-east China

Consumption of ready-to-drink beverages, as a potential source of fluoride (F), has increased considerably in China over the last decade. To help inform the public and policy makers, this study aimed to measure F concentration of ready-to-drink beverages on sale in Heilongjiang province, north east China. Three batches of 106 drink products manufactured by 26 companies were purchased from the main national supermarkets in Harbin, Heilongjiang province, China. The F concentration of all samples was determined, in triplicate, using a fluoride ion-selective electrode in conjunction with a meter and a direct method of analysis. The products were categorised into 10 groups according to product type. F concentrations of the samples ranged from 0.012–1.625 mg/l with a mean of 0.189 mg/l and a median of 0.076 mg/l. More than half of the products (55%) had an F concentration of ≤0.1 mg/l, while <5% had a F concentration of >0.7 mg/l. The ‘tea with milk’ group contained the highest mean F concentration (1.350 mg/l), whereas the lowest mean F concentration (0.027 mg/l) was found for the ‘fruit juice’ group. For some products, such as tea, fruit juice and carbonated beverages, there were substantial variations in F concentration between batches, manufacturers and production sites. In conclusion, ready-to-drink products (apart from tea), sold in Heilongjiang province, China, when consumed in moderation are unlikely to constitute a substantial risk factor for the development of dental or skeletal fluorosis.
