Effect of New Media on Political Participation in the Border Area of the Republic of Indonesia - The Democratic Republic of East Timor

Indonesia held the Legislative and Presidential Elections simultaneously on April 17, 2019. In these elections’ candidates and the success team actively used new media to influence voters. This research was conducted to find out how much influence the new media has on political participation in the 2019 elections, especially in Belu Regency as the border region of Indonesia-Timor Leste. The researchers previously examined the effect of the new media on the election of governors whose locations were in urban areas. In contrast to this study conducted in simultaneous elections located in rural areas in Belu Regency. This Research conducted in April 2019 with 282 respondents of beginner’s voter in Belu Regency. The independent variables examined in this study were affect new media (X) and dependent variables of voter participation (Y). The theories used in this study are stimulus response theory, magic bullet theory, and political participation concept. Based on linear regression analysis, the variable X has a positive effect on the variable Y. However, this effect is included in the weak category with a correlation rate of 31.5 percent.
Aggregate Public Debt Burden And The Growth Of A Fragile Economy: The Nigerian Experience

This study empirically investigates the combine influence of two components of public debt (internal and external public debt) burden on the growth of Nigerian emerging and fragile economy. The study adopts descriptive research design and an econometric estimation approach anchored on Vector Error Correction Estimation (VECM) in determining the impact of public debt accumulation on the long-run economic growth in Nigeria. Time series data which covered the periods of 1961-2013 as variously sourced were employed in the study. The empirical results from the study confirmed that public debt has a negative short-run and long-run impact on the Nigerian economic growth and the adjustment process from the result indicates a low speed of adjustment for the errors in the previous year to be corrected in equilibrium. The study’s existing findings are consistent with prior studies in other economies. The policy implication of this current finding is that an accumulation of public debts daunt the growth of Nigerian economy. The paper suggests that policy makers should always strive to ensure that debt-GDP ratio does not go beyond international ratio for debt sustainability in Nigeria.
Clinical Outcome after Anterior Cruciate Ligament Reconstruction Using Hamstring Tendon Autograft: A Prospective Study with 6 Months Follow-Up

Objective: The goal of our study is to show that after single-bundle anatomic ACL reconstruction technique using hamstring tendon autograft (quadrupled semitendinosus and gracillis tendons), there is excellent objective knee stability and the return of flexor muscles strength. Methods: 65 patients aged 13–46 entered our study and were operated with a single bundle ACL reconstruction technique using hamstring tendon autograft. The operation and postoperative protocol were standardized. Patients were evaluated at 3 and 6 months postoperatively with clinical examination, KT–1000 measurements, functional scores (Balance index, Hop index, IKDC, isokinetic testing) and subjective questionnaire (Lysholm score, Tegner score). Results: 65 patients were evaluated 3 and 6 months postoperatively. Lachman test was negative in 92% and the pivot-shift test was negative in 89% of patients at 6 months follow-up. KT–1000 stability testing revealed a difference of 1.05 mm ± 2.83. At final follow-up, overall IKDC evaluation grade A and B were obtained in 96% of patients. The mean Lysholm score, 6 months postoperative was 94. There was no statistically significant difference in the angle of peak torque inflexion at 60°/s at 6 months follow-up. Conclusion: Our study shows that the strength of knee flexion six months after harvesting both hamstring tendons returns. However, there is still a statistically significant difference in knee flexion peak torque, when comparing the operative and non-operative side. Single bundle anatomic ACL reconstruction gives excellent knee stability and good clinical results with normal knee range of motion and returns to the appropriate level of activity.

The importance of clinical leadership in the hospital setting

: In many areas of the developed world, contemporary hospital care is confronted by workforce challenges, changing consumer expectations and demands, fiscal constraints, increasing demands for access to care, a mandate to improve patient centered care, and issues concerned with levels of quality and safety of health care. Effective governance is crucial to efforts to maximize effective management of care in the hospital setting. Emerging from this complex literature is the role of leadership in the clinical setting. The importance of effective clinical leadership in ensuring a high quality health care system that consistently provides safe and efficient care has been reiterated in the scholarly literature and in various government reports. Recent inquiries, commissions, and reports have promoted clinician engagement and clinical leadership as critical to achieving and sustaining improvements to care quality and patient safety. In this discursive paper, we discuss clinical leadership in health care, consider published definitions of clinical leadership, synthesize the literature to describe the characteristics, qualities, or attributes required to be an effective clinical leader, consider clinical leadership in relation to hospital care, and discuss the facilitators and barriers to effective clinical leadership in the hospital sector. Despite the widespread recognition of the importance of effective clinical leadership to patient outcomes, there are some quite considerable barriers to participation in clinical leadership. Future strategies should aim to address these barriers so as to enhance the quality of clinical leadership in hospital care.
A local network neighbourhood artificial immune system

As information is becoming more available online and will forevermore be part of any business, the true value of the large amounts of stored data is in the discovery of hidden and unknown relations and connections or traits in the data. The acquisition of these hidden relations can influence strategic decisions which have an impact on the success of a business. Data clustering is one of many methods to partition data into different groups in such a way that data patterns within the same group share some common trait compared to patterns across different groups. This thesis proposes a new artificial immune model for the problem of data clustering. The new model is inspired by the network theory of immunology and differs from its network based predecessor models in its formation of artificial lymphocyte networks. The proposed model is first applied to data clustering problems in stationary environments. Two different techniques are then proposed which enhances the proposed artificial immune model to dynamically determine the number of clusters in a data set with minimal to no user interference. A technique to generate synthetic data sets for data clustering of non-stationary environments is then proposed. Lastly, the original proposed artificial immune model and the enhanced version to dynamically determine the number of clusters are then applied to generated synthetic non-stationary data clustering problems. The influence of the parameters on the clustering performance is investigated for all versions of the proposed artificial immune model and supported by empirical results and statistical hypothesis tests.
SketchSliders: Sketching Widgets for Visual Exploration on Wall Displays

We introduce a mobile sketching interface for exploring multi-dimensional datasets on wall displays. We demonstrate the idea of SketchSliders, range sliders that users can freely sketch on a mobile surface to customize their exploration. A small combination of sketches and gestures allows the creation of complex interactive sliders, such as circular sliders for periodic data, slider branches for detailed interaction, and fisheye transformation sliders. We augment sliders with a suite of tools, such as markers, slider cursors, and approximate views of data distributions. Our designs are inspired by a design study with three visualization experts and validated through a user study with six experts using our system. Our findings indicate that our sketching interface accommodates a wide range of exploration strategies, helping users customize as well as focus their visual explorations.
An analysis of fossil identification guides to improve data reporting in citizen science programs

An increasing number of organizations use untrained volunteers to gather scientific data. This citizen science movement builds enthusiasm for science by engaging the public, as well as providing a way to gather large amounts of data at little or no expense. The challenge of citizen science is obtaining accurate information from participants. Many citizen science programs encourage participants to use visual identification guides to ensure they provide correct data. Identifying an image style that increases correct identifications helps not only the citizen science movement but also scientific instruction in general. This study tests three image-based identification guides for identifying late Hemphillian (5–4.5 m.y.a.) fossils from Polk County, Florida. Each guide has identical layout and text, differing only in image style: color photos, grayscale photos, or illustrations. Untrained participants each use one guide to identify fossils. Geology and paleontology professionals also identify fossils for comparison. Comparing results reveals that color photographic images produce results most similar to data from professionals. In addition, participants provide data on their years of education, previous experience finding fossils, and enthusiasm about finding fossils. Analysis of this information reveals that participants with higher education and/or previous experience finding fossils produce data most similar to that from professionals. Paradoxically, participants with higher enthusiasm produce data less similar to that from professionals, while moderate interest levels correlated with greater similarity. Dava K. Butler.

Fluoride Rinses, Gels and Foams: An Update of Controlled Clinical Trials

Aim: The aim of this conference paper was to systematically review the quality of evidence and summarize the findings of clinical trials published after 2002 using fluoride mouth rinses, fluoride gels or foams for the prevention of dental caries. Methods: Relevant papers were selected after an electronic search for literature published in English between 2003 and 2014. The included papers were assessed for their risk of bias and the results were narratively synthesized due to study heterogeneity. The quality of evidence was expressed according to GRADE. Results: A total of 19 papers were included (6 on fluoride mouth rinse, 10 on fluoride gel and 3 on fluoride foam); 6 had a low risk of bias while 2 had a moderate risk. All fluoride measures appeared to be beneficial in preventing crown caries and reversing root caries, but the quality of evidence was graded as low for fluoride mouth rinse, moderate for fluoride gel and very low for acidulated fluoride foam. No conclusions could be drawn on the cost-effectiveness. Conclusions: This review, covering the recent decade, has further substantiated the evidence for a caries-preventive effect of fluoride mouth rinse, fluoride gel and foam, previously established in systematic reviews. The lack of clinical trials free from bias is, however, still a concern, especially for fluoride mouth rinses and fluoride foam. There is also a scientific knowledge gap on the benefit and optimal use of these fluoride supplements in combination with daily tooth brushing with fluoride toothpaste.
Do pathologists agree with each other on the histological assessment of pT1b oesophageal adenocarcinoma?

Background In early (T1) oesophageal adenocarcinoma (OAC), the histological profile of an endoscopic resection specimen plays a pivotal role in the prediction of lymph node metastasis and the potential need for oesophagectomy with lymphadenectomy. Objective To evaluate the inter-observer agreement of the histological assessment of submucosal (pT1b) OAC. Methods Surgical and endoscopic resection specimens with pT1b OAC were independently reviewed by three gastrointestinal pathologists. Agreement was determined by intraclass correlation coefficient for continuous variables, and Fleiss' kappa (κ) for categorical variables. Bland–Altman plots of the submucosal invasion depth were made. Results Eighty-five resection specimens with pT1b OAC were evaluated. The agreement was good for differentiation grade (κ=0.77, 95% confidence interval (CI) 0.68–0.87), excellent for lymphovascular invasion (κ=0.88, 95% CI 0.76–1.00) and moderate for submucosal invasion depth using the Paris and Pragmatic classifications (κ=0.60, 95% CI 0.49–0.72 and κ=0.42, 95% CI 0.33–0.51, respectively). Systematic mean differences between pathologists were detected for the measurement of submucosal invasion depth, ranging from 297 µm to 602 µm. Conclusions A substantial discordance was found between pathologists for the measurement of submucosal invasion depth in pT1b OAC. Differences may lead to an over- or underestimation of the lymph node metastasis risk, with grave implications for the treatment strategy. Review by a second gastrointestinal pathologist is recommended to improve differentiating between a favourable and an unfavourable histological profile.
Crescimento e deposio de nutrientes nos rgos de frangos de corte de duas linhagens comerciais

This work was carried out with the objective of studying the growth profile and the nutrients deposition on organs (heart, liver, gizzard, intestine and proventricle) of male and female broiler chickens from Ross and Cobb lineages. It was used 1,920 chicks at the age of one day placed in experimental shed boxes on the floor. The experimental design was completely randomized in a 2 × 2 factorial model composed of 2 sexes (mates and females) and two strains with 4 repetitions of 120 broilers each. The broilers were fed formulated diets to supply the nutrient requirements according to each breeding phase. After 24 hours of fasting, the broilers were weighed and slaughtered (1 to 56 days) every week. The weight and components of the organs (water, ash, protein and fat) were weekly obtained, with parameters estimated by the equation of Gompertz and the growth rates were determined by the derived of the equations. There was no influence of the strains on the deposition of nutrients on the heart. Ross chicks were more precocious on growth and on the deposition of water and ashes in the liver, therefore it presents a greater metabolic activity in digestion and nutrient synthesis. Cobb strain was more precocious in the development of the intestine and the growth and deposition of nutrients on the proventricle. Males are more precocious than females on the growth rate and on the protein, fat and water deposition in the gizzard.
Properties of Oriented Strandboard Produced Using Phenol-Formaldehyde Resin Synthesized with Bio-Oil of Lignocellulosic Wastes

The main objective of the present study was to modify phenol-formaldehyde (PF) resin by using bio-oil obtained by pyrolysis with and without alkali catalyst (potassium carbonate: K2CO3) (10 to 50 weight %) and determine technological properties oriented strandboard (OSB) panels produced using the modified PF resin formulations. The pine sawdust was used as a raw material of bio-oil. The chemical characterization of bio-oils was determined by GCMS analysis. The OSB panels were produced with the bio-based PF resins and then their technological properties were determined. As the amount of potassium carbonate catalyst increased up to 20 wt% in the PF resin, 24-h thickness swelling of OSB panels decreased from 15.4 to 14.3%, but further increment in the potassium carbonate catalyst content increased the thickness swelling (22.8%). The IB strength of the OSB specimens with PF resin with 10 wt% bio-oil produced with catalyst or pyrolysis process was found the same (2.18 N/mm2) and it was higher than the reference value (1.97 N/mm2). As the amount of bio-oil was increased to 20 wt%, the difference in the IB values between treated OSB and reference OSB was negligible. However, above the 20 wt% bio oil, it was observed a decreasing trend in the IB values. The bending strength and bending modulus of the OSB specimens containing 20 wt% bio-oil were also found to be higher than those of the reference OSB specimens. It was concluded that the PF resin synthesized using bio-oil of (20 wt%) produced with and without alkali catalyst could be successfully used in the production of the OSB.
Functional Outcome Study of Infected Non Union of Long Bones Managed by Antibiotic Cement Coated Intramedullary Interlocking Nail

Background: Any fracture that shows no clinical or radiological union in a reasonable time, for that specific injury, host and management strategy is termed as non union. It has been shown that about 65% of patients with open fractures have wound contamination with micro-organisms . Therefore it can be said that antibiotics are not just for prophylaxis but rather for treatment of wound contamination per se. Early onset infection respond well to antibiotics and has good outcome. In delayed and late onset infection, there will be formation of biofilm associated with mechanical instability due to fixation failure. The treatment of biofilm related infections and infected non-union include AO external fixator, monorail fixator, Ilizarov ring fixator, Taylor’s spatial frame.The main aim of the study is To study the outcome of infection control and bony union achieved by antibiotic cement coated interlocking intramedullary nail in cases of infected non-union of long bones. Materials and methods: This is a short term prospective and retrospective study conducted over a period of 2 years. 20 patients, above 18 years of age who were admitted or on follow-up between August 2017 and August 2019 were considered for the study. The patients with infected non-union with or without implant in situ were included. This included both groups of patient who were already operated with definitive internal fixation which got infected with no signs of union and also patients with compound fractures maintained on external fixator that showed no union with active or quiescent infection at the end of 3 months. The patients who were diagnosed as infected non-union planned for antibiotic cement coated interlocking intramedullary nail were evaluated for surgery as per routine protocol of the institution Results: In our study infection control or no recurrence of infection was seen in 15 patients and also bony union was achieved in 15 patients which accounts for 75 % of the study population. The average duration for achieving bony union was 22.5 weeks for tibia and 29.7 weeks for femur. 3 patients had both persistent infection and non-union. 1 patient was in the femur group and the other 2 patients in the tibia group Conclusion: The antibiotic cement coated interlocking nail is a good treatment method for infected non-union of long bones providing good results in patients with bone defect less than 1 cm without the requirement of additional procedures. Key Word: Infection, non union, antibiotic, nail. -------------------------------------------------------------------------------------------------------------------------------------Date of Submission: 11-02-2020 Date of Acceptance: 27-02-2020 -------------------------------------------------------------------------------------------------------------------------------------
