User-Generated Content and Bias in News Media
Authors: Yildirim Pinar , Gal-Or Esther , Geylani Tansev 
Published: July 2013

In this study, we investigate newspapers' decision to expand their product lines by adding online editions that incorporate user-generated content. We demonstrate that such product line extensions mitigate the extent of slanting in print media. The results also show that as the extent of discretion of users to generate online content increases, print versions of newspapers become more polarized. Furthermore, adding online editions results in reduced profits for newspapers as the additional product variants increase the intensity of competition in the market and the discretion awarded to users limits the ability of newspapers to extract rents from consumers.

Engineering Students' Use of and Satisfaction With Faculty and Professional Academic Advising Systems
Authors: Jaffé William F. , Huba Mary E. 
Published: July 2013

The academic advising program in a college of engineering was studied to describe the role of the advisor in terms of Predominant patterns of use for assistance with preregistration, class add/drop, curriculum planning, career guidance, college and department rules and procedures, and personal counseling. Faculty and professional advisors were compared, and student gender, grade point average (GPA), and age were studied. Students used their advisors predominantly for assislance with preregistration, curriculum planning, and adding or dropping classes. Students assigned to faculty advisors reported greater use of and satisfaction with their advisors than students assigned professional advisors. No discernable pattern of use of and satisfaction with the assigned advisor was found with regard to gender. The expectation was not generally supported that females would use and be more satisfied with their advisors than would males.
Students with higher GPAs reported greater use of and satisfaction with their advisors for curriculum and registration assistance than students with lower GPAs. Furthermore, for several advising needs, students with higher GPAs who had assigned faculty advisors used or were more satisfied with their assigned advisors than similar students assigned professional advisors.
Younger students used their advisors more frequently than older students for career guidance and personal counseling. This was especially true for younger students assigned to faculty advisors.

Academic Advising During Program Discontinuance
Authors: Maher Michelle A. 
Published: July 2013

Academic program closure is explored and student advising needs that emerged in 3 stages of program decline and discontinuation are identified. Data from interviews and advising communication of 20 graduate students enrolled in a master of education program targeted for discontinuation were qualitatively analyzed within a framework of an organizational death model. Findings indicate that program decline and discontinuation require academic advisors to understand and respond to a range of advising needs that vary with the phase of program closure: addressing students' emotional responses of grief, anger, and betrayal as well as managing student concerns over the loss of professional identity and lack of a professional network. Recommendations are offered for faculty advisors caught in the midst of program discontinuation.

Advising Students About Required Grade-Point Averages
Authors: Moore W. Kent 
Published: July 2013

Sophomores interested in professional colleges with grade-point average (GPA) standards for admission to upper division courses will need specific and realistic information concerning the requirements. Specifically, those who fall short of the standard must assess the likelihood of achieving the necessary GPA for professional program admission. The Excel spreadsheet described in this paper yields quantitative data that serve as a basis for clear communication and effective advising. For students who have a high probability of success, the information provides a target, and the accompanying advising can increase motivation to reach it. Conversely, students not likely to attain the necessary GPA can be more easily convinced to redirect their time and energy into another major in which they can be successful.

Significant Learning, Significant Advising
Authors: Kelley Bruce 
Published: July 2013

The acknowledgment that advisees are learners and advisors are teachers may be the most powerful philosophical change in advising in 30 years. This article builds generally on the growing momentum to view academic advising as an extension of student learning, and specifically as an expansion of “Advising as Learning” in which Hemwall and Trachte (2005) argued that “learning as an organizing paradigm has profound implications” (p. 75). I develop this idea by applying Fink's (2003) learning paradigm to advising. The synergy in this paradigm can be harnessed to create advising that causes change in the advisee. Fink's method for developing opportunities for significant learning requires forethought and careful design when applied to the academic advising process.

Students' Motivation to Access Academic Advising Services
Authors: Henning Marcus A. 
Published: July 2013

The interrelationships between motivation for choosing a program of study, intention to access academic advisors, academic difficulty, and actual appointments with academic advisors were based on student self-reports of motivation and intentions. In addition, academic achievement measures and data on student access to academic advisors were obtained. Motivation level at the beginning of enrollment and academic difficulty at the end of the semester were not significantly related to intended or actual appointments with academic advisors. However, subtle trends indicate that students with higher levels of motivation, including those in academic difficulty, saw academic advisors more than did their less motivated peers. Notions of expectancy value, self-worth, goal orientation, and self-concept were the theoretical frameworks used in the analysis.

Forging Connections: An Investigation of New Students' Perspectives of Their Transition to the University
Authors: Baruch-Runyon Adele , VanZandt Zark , Elliott S. Auguste 
Published: July 2013

We studied first-year students through an integrated group workshop and longitudinal interviews that focused on students' transitional experience at the university as well as the strategies they developed to adjust to university life. Four themes emerged: the challenges of forming connections to other students with similar interests during the first few weeks on campus, the need to balance competing demands, varied experiences of connection with faculty and staff, and the need for translation of university life for minority students. To address the issues and concerns that emerged from our findings, we offer a number of advisory recommendations and programmatic initiatives.

Objectives This study aims to assess the correlation of CT-based structural rigidity analysis with mechanically determined axial rigidity in normal and metabolically diseased rat bone. Methods A total of 30 rats were divided equally into normal, ovariectomized, and partially nephrectomized groups. Cortical and trabecular bone segments from each animal underwent micro-CT to assess their average and minimum axial rigidities using structural rigidity analysis. Following imaging, all specimens were subjected to uniaxial compression and assessment of mechanically-derived axial rigidity. Results The average structural rigidity-based axial rigidity was well correlated with the average mechanically-derived axial rigidity results (R2 = 0.74). This correlation improved significantly (p < 0.0001) when the CT-based Structural Rigidity Analysis (CTRA) minimum axial rigidity was correlated to the mechanically-derived minimum axial rigidity results (R2 = 0.84). Tests of slopes in the mixed model regression analysis indicated a significantly steeper slope for the average axial rigidity compared with the minimum axial rigidity (p = 0.028) and a significant difference in the intercepts (p = 0.022). The CTRA average and minimum axial rigidities were correlated with the mechanically-derived average and minimum axial rigidities using paired t-test analysis (p = 0.37 and p = 0.18, respectively). Conclusions In summary, the results of this study suggest that structural rigidity analysis of micro-CT data can be used to accurately and quantitatively measure the axial rigidity of bones with metabolic pathologies in an experimental rat model. It appears that minimum axial rigidity is a better model for measuring bone rigidity than average axial rigidity.

Published: July 2013

Objectives We aimed first to summarise minimal clinically important differences (MCIDs) after total hip (THR) or knee replacement (TKR) in health-related quality of life (HRQoL), measured using the Short-Form 36 (SF-36). Secondly, we aimed to improve the precision of MCID estimates by means of meta-analysis. Methods We conducted a systematic review of English and non-English articles using MEDLINE, the Cochrane Controlled Trials Register (1960–2011), EMBASE (1991–2011), Web of Science, Academic Search Premier and Science Direct. Bibliographies of included studies were searched in order to find additional studies. Search terms included MCID or minimal clinically important change, THR or TKR and Short-Form 36. We included longitudinal studies that estimated MCID of SF-36 after THR or TKR. Results Three studies met our inclusion criteria, describing a distinct study population: primary THR, primary TKR and revision THR. No synthesis of study results can be given. Conclusions Although we found MCIDs in HRQoL after THR or TKR have limited precision and are not validated using external criteria, these are still the best known estimates of MCIDs in HRQoL after THR and TKR to date. We therefore advise these MCIDs to be used as absolute thresholds, but with caution.
Muscle ‘regenerative potential’ determines physical recovery following total knee replacement

Published: July 2013

Objectives Lower limb muscle power is thought to influence outcome following total knee replacement (TKR). Post-operative deficits in muscle strength are commonly reported, although not explained. We hypothesised that post-operative recovery of lower limb muscle power would be influenced by the number of satellite cells in the quadriceps muscle at time of surgery. Methods Biopsies were obtained from 29 patients undergoing TKR. Power output was assessed pre-operatively and at six and 26 weeks post-operatively with a Leg Extensor Power Rig and data were scaled for body weight. Satellite cell content was assessed in two separate analyses, the first cohort (n = 18) using immunohistochemistry and the second (n = 11) by a new quantitative polymerase chain reaction (q-PCR) protocol for Pax-7 (generic satellite cell marker) and Neural Cell Adhesion Molecule (NCAM; marker of activated cells). Results A significant improvement in power output was observed post-operatively with a mean improvement of 19.7 W (95% confidence interval (CI) 14.43 to 30.07; p < 0.001) in the first cohort and 27.5 W (95% CI 13.2 to 41.9; p = 0.002) in the second. A strong correlation was noted between satellite cell number (immunohistochemistry) and improvement in patient power output (r = 0.64, p = 0.008). Strong correlation was also observed between the expression of Pax-7 and power output (r = 0.79, p = 0.004), and the expression of NCAM and power output (r = 0.84, p = 0.001). The generic marker explained 58% of the variation in power output, and the marker of activated cells 67%. Conclusions Muscle satellite cell content may determine improvement in lower limb power generation (and thus function) following TKR.
Metastatic bone disease

Published: July 2013

Objectives Guidelines for the management of patients with metastatic bone disease (MBD) have been available to the orthopaedic community for more than a decade, with little improvement in service provision to this increasingly large patient group. Improvements in adjuvant and neo-adjuvant treatments have increased both the number and overall survival of patients living with MBD. As a consequence the incidence of complications of MBD presenting to surgeons has increased and is set to increase further. The British Orthopaedic Oncology Society (BOOS) are to publish more revised detailed guidelines on what represents ‘best practice’ in managing patients with MBD. This article is designed to coincide with and publicise new BOOS guidelines and once again champion the cause of patients with MBD. Methods A series of short cases highlight common errors frequently being made in managing patients with MBD despite the availability of guidelines. Results Despite guidelines for the management of patients with MBD being available for more than a decade basic errors in management continue to be made, affecting patient survival and quality of life. Conclusions It is hoped that by publicising the new BOOS guidelines the management of patients with MBD will improve over the next decade, significantly more than it has over the last decade.

Published: July 2013

BACKGROUND
Growth differentiation factor-15 (GDF-15), soluble ST2 (sST2), and high-sensitivity troponin I (hsTnI) are emerging predictors of adverse clinical outcomes. We examined whether circulating concentrations are related to the development of kidney disease in the community.

METHODS
Plasma GDF-15, sST2, and hsTnI concentrations were measured in 2614 Framingham Offspring cohort participants (mean age 57 years, 54% women) at the sixth examination cycle (1995–1998). Associations of biomarkers with incident chronic kidney disease [CKD, eGFR &lt;60 mL · min−1 · (1.73 m2) −1, n = 276], microalbuminuria (urinary albumin to creatinine ratio ≥25 mg/g in women and 17 mg/g in men, n = 191), and rapid decline in renal function [decline in eGFR ≥3 mL · min−1 · (1.73 m2) −1 per year, n = 237], were evaluated using multivariable logistic regression; P &lt; 0.006 was considered statistically significant in primary analyses.

RESULTS
Participants were followed over a mean of 9.5 years. Higher plasma GDF-15 was associated with incident CKD [multivariable-adjusted odds ratio (OR) 1.9 per 1-U increase in log-GDF-15, 95% CI 1.6–2.3, P &lt; 0.0001] and rapid decline in renal function (OR, 1.6; 95% CI, 1.3–1.8; P &lt; 0.0001). GDF-15, sST2, and hsTnI had suggestive associations with incident microalbuminuria but did not meet the prespecified P-value threshold after multivariable adjustment. Adding plasma GDF-15 to clinical covariates improved risk prediction of incident CKD: the c-statistic increased from 0.826 to 0.845 (P = 0.0007), and categorical net reclassification was 6.3% (95% CI, 2.7–9.9%).

CONCLUSIONS
Higher circulating GDF-15 is associated with incident renal outcomes and improves risk prediction of incident CKD. These findings may provide insights into the mechanisms of renal injury.
The Correlation of Activity Coefficients of Ionic Species of Aqueous Electrolytes Using a New Model
Authors: Amooey Ali Akbar 
Published: July 2013

Abstract
This study proposed a new model based on the solvation phenomena. The ionic activity coefficients of individual ions of some 1:1 and 1:2 salts were correlated successfully. Comparison was made between the results of the present model and those of Khoshkbarchi–Vera (KV), Pitzer, and Lin–Lee models. The average relative errors for cation and anion were 3.03, 3.53, 3.45 and 1.24, 1.14, 1.38, respectively, in Lin–Lee, KV, Pitzer models, whereas they are 1.81 and 0.66 in the proposed model.These results show that the proposed model improved the correlation of the individual ionic activity coefficients. Contrary to arguments found in the literature, it is also demonstrated that the short-range solvation contribution is a linear function of ionic strength.
A New Wrapped Ensemble Approach for Financial Forecast

Published: July 2013

AbstractThe financial market is a highly complex and dynamic system that has great commercial value; thus, many financial elite are drawn to research on the subject. Recent studies show that machine learning methods perform better than traditional statistical ones. In our study, based on the characteristics of financial sequence data, we propose a wrapped ensemble approach using a supervised learning algorithm to predict stock price volatility of China’s stock markets. To check our new approach, we developed an intelligent financial forecast system and used the Hushen 300 index data to test our model; it proves that our model performs better than a single algorithm. We also compared our model with the famous ensemble approach of bagging, and the result shows that our model is better.

Ergonomics Observation: Harvesting Tasks at Oil Palm Plantation: Yee Guan NG, et al. Department of Environmental and Occupational Health, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, Malaysia—ObjectivesProduction agriculture is commonly associated with high prevalence of ergonomic injuries, particularly during intensive manual labor and during harvesting. This paper intends to briefly describe an overview of oil palm plantation management highlighting the ergonomics problem each of the breakdown task analysis.MethodsAlthough cross‐sectional field visits were conducted in the current study, insight into past and present occupational safety and health concerns particularly regarding the ergonomics of oil palm plantations was further exploited. Besides discussion, video recordings were extensively used for ergonomics analysis.ResultsThe unique commodity of oil palm plantations presents significantly different ergonomics risk factors for fresh fruit bunch (FFB) cutters during different stages of harvesting. Although the ergonomics risk factors remain the same for FFB collectors, the intensity of manual lifting increases significantly with the age of the oil palm trees‐weight of FFB.ConclusionsThere is urgent need to establish surveillance in order to determine the current prevalence of ergonomic injuries. Thereafter, ergonomics interventions that are holistic and comprehensive should be conducted and evaluated for their efficacy using approaches that are integrated, participatory and cost‐effective.
Removal of TaN/Ta Barrier with Variable Selectivity to Copper and TEOS
Authors: Bian Jinru , Quanci John , VanHanehem Matthew 
Published: July 2013

AbstractHighly selective 2nd step copper slurries developed by Rodel have efficient barrier (TaN) polishing rates at extremely low down force (1000 Å/min at one psi, and 2000 Å/min at 3 psi). Removal rates of dielectrics (TEOS or low k CDO) can be independently adjusted from zero to nearly any designed value and copper removal rates can be independently controlled from 20 to 500 Å /min, while maintaining the high barrier removal rates. In addition, zero loss of low-k dielectric capping layers has been demonstrated, and zero loss of high metal density (90%) domain of pattern wafers with 30 seconds overpolishing has been demonstrated. Experiments also show that the high selectivity is a true CMP effect and not due to static etching.
Oscillative surface morphology in peritectic NiAl using phase-field modeling
Authors: Kist Marius , Choudhury Abhik , Nestler Britta 
Published: July 2013

AbstractThe NiAl-γ–γ′-system is numerically modeled using a multi-phase-field approach near its peritectic. The free energies are approximated as second order polynomials of the concentration. The parameters of these functions are fitted using experimentally determined values for the peritectic equilibrium concentrations and the liquidus/solidus slopes at the peritectic temperature. A study on lateral growth of a peritectic phase (γ') layer on a primary (γ) substrate reveals an oscillation of the layer interfaces at very low undercoolings (0.08 K). This morphology has its seeds in an oscillatory rotation of the triple junction. A mechanism for the origin of rotation is described and a reason for its disappearance at higher undercoolings is discussed. While the γ–γ′ surface energy as well as the γ interdiffusion constant are unknown, the influence of these parameters on the oscillation morphology is investigated.
