Operative game monitoring as a fundamental for a football players efficiency evaluation
Authors: Panfil Ryszard , Mazur Leszek 
Published: June 2018

Operative monitoring of the game means objective and regular, based on the rules, observation of the game. The groundwork of the observation makes the basis of the evaluation players’ actions. According to the existing threats which come from the regular, commonly used analysis and evaluation of actions on team games, the authors want to present the innovative tool which allows monitoring and evaluation of actions and therefore raises the level of effectiveness of the teams. The use of this innovative tool is presented on the two examples of the teams: one from the best polish league (“Ekstraklasa”) and one from 5th polish division team. The applied method fulfills its aims, allows the individual evaluation of the players and also actives players to do as much as they could to raise up the score of the whole game. This method determines the authors to prepare another method for individual reward of the players.
Fluid Teams and Knowledge Retrieval: Scaling Service Operations
Authors: Valentine Melissa A. , Tan Tom Fangyun , Staats Bradley R. , Edmondson Amy C. 
Published: June 2018

To scale service operations requires retrieving knowledge across the organization. However, prior work highlights that individuals on the periphery of organizational knowledge networks may struggle to access useful knowledge at work. A knowledge repository has the potential to help peripheral individuals gain access to valuable knowledge because it is universally available and can be used without social interaction. However, for it to successfully serve this equalizing function, those on the periphery of the organizational knowledge networks must actually use it, possibly overcoming barriers to doing so. In this paper, we develop a multilevel model of knowledge retrieval in teams to explore how individuals on the periphery of knowledge networks—because of their inexperience, location, lack of social capital, gender, or role—access knowledge from such a knowledge repository. Unexpectedly, we find that individuals whose experience and position already provide access to vital knowledge use a knowledge repository more frequently than individuals on the organizational periphery. We argue that this occurs because the knowledge repository—despite its appearance of equivalent accessibility—is actually more accessible to central than to peripheral players. Thus, knowledge retrieval is not driven primarily by the need to overcome limited access to other knowledge sources. Rather knowledge retrieval is facilitated when actors know how to reap value from the knowledge repository, which ironically improves with increasing access to other sources of knowledge. We conclude that a knowledge repository is unlikely to scale service operations without additional intervention.

The palliative chemotherapy decision and experiences of South African patients and their families
Authors: Potgieter Theola , Maree Johanna E 
Published: June 2018

Aims: To describe what motivates cancer patients, treated at a private cancer care centre in Port Elizabeth, South Africa, to undergo palliative chemotherapy and how the patients and their families experienced this treatment. Methods: A descriptive qualitative design was used. Researchers conducted 22 in-depth interviews with 11 purposively selected patients and 11 family members nominated by the patients. Qualitative content analysis was used to analyse the data. Findings: The patient participants consisted of two males and nine females between the ages 40 and 79, who had been diagnosed with various cancers. The family members consisted of six husbands, two wives and three sons, with ages ranging from 20 to 79. Three themes arose from the patient data and three from the family data. Conclusion: Hope informed the palliative treatment decision. Despite being told that the chemotherapy would not cure them, patients hoped for additional time and even a cure. The families supported the patient's decision and shared their hopes. The family members were aware of the side effects their loved ones were experiencing, but still experienced the treatment as positive. Giving and receiving support was important and religion, the families and staff and fellow patients at the cancer care centre were identified as sources of support.

Published: June 2018

Objectives The aim of this study was to investigate the role of miR-126 in the development of osteoarthritis, as well as the potential molecular mechanisms involved, in order to provide a theoretical basis for osteoarthritis treatment and a novel perspective for clinical therapy. Methods Human chondrocyte cell line CHON-001 was administrated by different doses of interleukin (IL)-1β to simulate inflammation. Cell viability, migration, apoptosis, IL-6, IL-8, and tumour necrosis factor (TNF)-α expression, as well as expression of apoptosis-related factors, were measured to assess inflammation. miR-126 expression was measured by quantitative polymerase chain reaction (qPCR). Cells were then transfected with miR-126 inhibitor to assess the effect of miR-126 on IL-1β-injured CHON-001 cells. Expression of B-cell lymphoma 2 (Bcl-2) and the activity of mitogen-activated protein kinase (MAPK) / Jun N-terminal kinase (JNK) signaling pathway were measured by Western blot to explore the underlying mechanism through which miR-126 affects IL-1β-induced inflammation. Results After IL-1β administration, cell viability and migration were suppressed while apoptosis was enhanced. Expression of IL-6, IL-8, and TNF-α were all increased, and miR-126 was upregulated. In IL-1β-administrated CHON-001 cells, miR-126 inhibitor suppressed the effect of IL-1β on cell viability, migration, apoptosis, and inflammatory response. Bcl-2 expression was negatively regulated with miR-126 in IL-1β-administrated cells, and thus affected expressions of phosphorylated MAPK and JNK. Conclusion IL-1β-induced inflammatory markers and miR-126 was upregulated. Inhibition of miR-126 decreased IL-1β-induced inflammation and cell apoptosis, and upregulated Bcl-2 expression via inactivating the MAKP/JNK signalling pathway. Cite this article: C. D. Yu, W. H.

Published: June 2018

Objective: To evaluate if alcoholic beverages can cause color change in composite resins, if the alcoholic concentration influences this variation besides analyzing within the composite resins tested, which would present greater color stability when subjected to the experiment. Material and Methods: 90 specimens of three different composite resins (IPS Empress Direct, Grandio®So and Filtek Z350 XT) were immersed in distilled water (control group), red wine and vodka. The samples were 2 mm thick and 8 mm in diameter, photopolymerized for 20 s on each side, polished with sandpaper, silicon carbide tip and felt disc with prophylactic paste and immersed in distilled water at 37 °C for 24 h prior to subgrouping. For the evaluation of the color variation, the formula prioritized by the CIEL *a *b* system was used. Data were analyzed by ANOVA and Tukey’s test at 95% significance. Results: The lowest variations occurred with the Grandio®So resin when exposed to wine, and Filtek Z350 XT when exposed to vodka. There was a statistically significant difference between the groups in water (p < 0.01) and in red wine (p < 0.01), but not in vodka (p > 0.05). The soaking medium that most caused staining was red wine. Conclusion: Red wine was the drink that generated the highest staining in all the resins tested, vodka did not change color stability significantly, the alcoholic concentrations tested did not directly influence the color change and the composite resin Grandio®So presented greater color stability when exposed to red wine.

Published: June 2018

Stafne bone defect or mandibular bone depression is defined as a bone developmental defect usually filled with soft or salivary gland tissue. Lingual posterior variant incidence is less than 0.5%. We reported a case of an 80 years old Asian female asymptomatic patient who underwent routine panoramic radiographic examination and a radiolucent area in mandible was noticed as an incidental finding, with an initial provisional diagnosis of traumatic bone cyst, aneurysmal bone cyst and lingual mandibular bone defect. The patient was then referred to multislice computed tomography and magnetic resonance imaging. Computed tomography showed a hypodense area with discontinuity in mandible base. Magnetic resonance imaging demonstrated a hyperintense image eroding mandibular body in contact with submandibular gland, which corresponded to fatty tissue and due to these imaging findings, the final diagnosis was lingual mandibular bone defect. Although the defect is a benign lesion and interventional treatment is not necessary, radiolucencies in mandible should be detailed investigated, due to their radiographic features that can resemble to other intrabony lesions. Imaging examinations can provide great defect details, especially magnetic resonance imaging, which can allow the identification of glandular tissue continuity to the mandibular defect.KeywordsBone cysts; Salivary glands; Magnetic resonance imaging; Computed tomography; Panoramic radiography.

Published: June 2018

Objective: To assess the influence of type 2 diabetes on bone mineral density in a group of type 2 diabetic patients, in comparison with non-diabetic patients. Additionally, to evaluate the correlation between mandibular cortical index and bone mineral density. Material and Methods: 48 patients (24 diabetics and 24 non-diabetics) referred for femur and spine densitometry and panoramic radiograph examination were included in this study. Patients were diagnosed based on densitometric results of the total femur and total spine. All panoramic radiomorphometric measurements were performed by 3 observers. Differences in T and Z-scores between both groups were evaluated with Mann-Whitney test and non-parametric correlations between mandibular cortical index and T/Z-scores were carried out with Spearman’s test. Results: Median T and Z-scores for total femur and total spine presented no statistical significant difference between diabetic and non-diabetic patients. In addition, only diabetics total femur and non-diabetics total spine T-scores were significantly correlated with mandibular cortical index. Conclusion: The present results suggest that type 2 diabetic patients have similar Z and T-scores in femur and spine when compared to non-diabetic patients. Mandibular cortical index, assessed on panoramic radiographs is inversely correlated with femur densitometry results in diabetics and spine bone mineral density in non-diabetic patients.

An intelligible deep convolution neural network based approach for classification of diabetic retinopathy
Authors: Sharma Sunil , Maheshwari Saumil , Shukla Anupam 
Published: June 2018

Abstract
Deep convolution neural networks (CNNs) have demonstrated their capabilities in modern-day medical image classification and analysis. The vital edge of deep CNN over other techniques is their ability to train without expert knowledge. Time bound detection is very beneficial for the early cure of disease. In this paper, a deep CNN architecture is proposed to classify nondiabetic retinopathy and diabetic retinopathy fundus eye images. Kaggle 2015 diabetic retinopathy competition dataset and messier experiment dataset are used in this study. The proposed deep CNN algorithm produces significant results with 93% area under the curve (AUC) for the Kaggle dataset and 91% AUC for the Messidor dataset. The sensitivity and specificity for the Kaggle dataset are 90.22% and 85.13%, respectively; the corresponding values of the Messidor dataset are 91.07% and 80.23%, respectively. The results outperformed many existing studies. The present architecture is a promising tool for diabetic retinopathy image classification.

Use of discriminated nondimensionalization in the search of universal solutions for 2-D rectangular and cylindrical consolidation problems
Authors: García-Ros Gonzalo , Alhama Iván , Cánovas Manuel 
Published: June 2018

Abstract
The solution to the 2-D consolidation problem, both for rectangular and cylindrical domains, has been widely studied in the scientific literature, reporting the most precise solutions in the form of analytical expressions difficult to handle for the engineer due to the high number of parameters involved. In this paper, after introducing a precise definition of the characteristic time, both this magnitude and the average degree of consolidation are obtained in terms of the least number of dimensionless groups that rule the problem. To do this, the groups are firstly derived from the dimensionless governing equations deduced from the mathematical model, following a discriminated nondimensionalization procedure which provides new groups that cannot be obtained by classical nondimensionalization. By a large number of numerical simulations, the dependences of the characteristic time and the average degree of consolidation on the new dimensionless groups have allowed to represent these unknowns graphically in the form of universal curves. This allows these quantities to be read with the least mathematical effort. A case study is solved to demonstrate the reliability and accuracy of the results.
New models of L2 achievement based on EFL learners’ joint attention and their emotional, social, and cultural capitals
Authors: Piri Somaye , Pishghadam Reza , Rasekh Zohreh Eslami 
Published: June 2018

AbstractThis study aimed at investigating the influence of learners’ previously acquired capitals on their response to the teacher’s attempts to trigger their attention. For this purpose, 403 EFL learners completed three different questionnaires. The results of Structural Equation Modeling showed that emotional capital was a positive predictor of interpersonal, intrapersonal, visual, musical, and kinesthetic joint attention styles. Similarly, social capital was a positive predictor of interpersonal, verbal, visual, and musical styles, and cultural capital was a positive predictor of logical and verbal styles. Moreover, the proposed model of L2 achievement based on the capitals and joint attention styles showed good fit to the data. It appears that learners’ socio-cultural and emotional backgrounds influence their response to the teacher’s initiation of joint attention. And their L2 achievement is enhanced when the teacher uses different joint attention modalities. In the end, pedagogical implications and areas for further research were provided.
The German Model of Industrial Relations: (Where) Does It Still Exist?
Authors: Oberfichtner Michael , Schnabel Claus 
Published: June 2018

AbstractUsing data from the representative IAB Establishment Panel, this paper charts changes in the two main pillars of the German IR model over the last 20 years. It shows that collective bargaining coverage and worker representation via works councils have substantially fallen outside the public sector. Less formalized and weaker institutions such as voluntary orientation of uncovered firms towards sectoral agreements and alternative forms of employee representation at the work-place have partly attenuated the overall erosion in coverage. Multivariate analyses indicate that the traditional German IR model (with both collective agreements and works councils) is more likely found in larger and older plants, and it is less likely in plants managed by the owner, in single and foreign-owned plants, in individually-owned firms or partnerships, and in exporting plants. In contrast, more than 60 % of German plants did not exhibit bargaining coverage or orientation or any kind of worker representation in 2015. Such an absence of the main institutional features of the German IR model is mainly found in small and medium-sized plants, in particular in the service sector and in eastern Germany, and its extent is increasing dramatically.
Liberal Financial Markets in the Interest of Staatskredite – A Process-Tracing Study of the Link between Sovereign Debt Policy and the 1908 Bourse Law Reform in the German Empire
Authors: Trampusch Christine 
Published: June 2018

Abstract
This study of the reform of the German Bourse Law in 1908 argues that the “self-undermining negative policy feedback effects” of the initial Bourse Law of 1896 on the market for Imperial and state bonds explain why exchange regulation was liberalized although the dominant political forces, the Conservatives and the Clericals, were opposed to bourses and capital markets. Based on an original assessment of primary documents, the study uses the method of explaining-outcome process tracing to show that the initial Bourse Law caused losses to the Imperial government and the large banks; this induced both actors to remove the prohibition of speculation. Because the German Empire can be viewed as a kind of laboratory for (first) treatment effects on financial market regulation of the sovereign debt market, this study contains lessons for understanding the relationship between states and financial markets in general.

Published: June 2018

Abstract

Background & methods
We investigated the in vitro antioxidant and antifungal activity by agar disc diffusion assay of leaf extract of some stinging plants namely, Urtica dioica L., Tragia involucrate L., Carduus nutans L. and Mucuna pruriens (L.) DC., against pathogenic fungi causing infections/diseases.

Results

M. pruriens (Disc 4), T. involucrate (Disc 2), U. dioica (Disc 1) showed significant antifungal activity against all tested pathogens, while C. nutans (Disc 3) showed intermediate activity against only Chaetomium globosum (Cg). The leaf extract of M. Pruriens showed maximum total phenol content (~1004 µg g−1 dry wt) followed by T. involucrate, C. nutans and U. dioica. However, the ascorbate was observed highest in T. involucrate (~10.3 µg g−1 dry wt) followed by M. pruriens (~9.2 µg g−1 dry wt) but the difference was not significant (p ≤ 0.05). Likewise, M. pruriens showed maximum anthocyanin content (~0.3 µg g−1 dry wt). The activity of antioxidant enzymes revealed that M. Pruriens showed maximum ascorbate peroxidase (APX) activity, while the highest guaiacol peroxidase (GPX) and catalase (CAT) activities were observed in C. nutans and U. dioica, respectively.

Conclusions

M. Pruriens showed potential in vitro antioxidant and antifungal activity against studied pathogens that may be used for ethno-pharmacological uses.
