Radiographic evaluation of tibial component alignment in total knee arthroplasty following extramedullary and intramedullary tibial referencing
Authors: Harikrishnan B. , Prabhakara Anjan , Joshi Gururaj R. 
Published: October 2017

<p class="abstract"><strong>Background:</strong> Long term survivorship of total knee arthroplasty (TKA) is significantly dependant on prostheses alignment. The debate on optimal referencing for femoral component is largely resolved with Intra-medullary jigs reproducing superior alignment. However there is still a contention about whether intramedullary or extramedullary jigs are better for tibial referencing. This study aims to compare the accuracy of tibial component alignment in TKA using intramedullary and extramedullary tibial referencing jigs.</p><p class="abstract"><strong>Methods:</strong> Between December 2012 and September 2014, 66 primary conventional cemented TKAs were performed using Nexgen-LPS Flex (Zimmer) implants in 55 patients, 50-80 y old (mean 65.54 y) with osteoarthritis/rheumatoid arthritis. Intramedullary and extramedullary tibial referencing was used in alternate patients undergoing TKA after excluding patients with BMI <span style="text-decoration: underline;">&gt;</span>35 kg/m<sup>2</sup>, knee deformity <span style="text-decoration: underline;">&gt;</span>15<sup>0</sup>,excessive tibial bowing, previous fractures/surgeries/retained metalwork around knee. Postoperatively, tibial component alignment (TCA) in coronal plane was assessed using AP radiograph of leg. A 3<sup>º</sup> cutoff from neutral mechanical axis (i.e., 90<sup>o</sup>±3<sup>o</sup>) was considered acceptable.<strong></strong></p><p class="abstract"><strong>Results:</strong> The intramedullary group (n=33) had 4 outliers (TCA &gt;93<sup>º</sup> or &lt;87<sup>º</sup>) whereas the extramedullary group (n=33) had 7 outliers (p=0.511). The difference in mean TCA between intramedullary and extramedullary groups was not statistically significant [90.70±2.43 and 90.55±2.17 (p=0.790)]. There were no significant per-operative/post-operative complications in either group.</p><p><strong>Conclusions:</strong> We conclude that both intramedullary and extramedullary tibial referencing guides can be used to achieve desired tibial component alignment (90±3<sup>º</sup>) in TKA.

Published: October 2017

<p>We have previously found that <em>Sema5A, </em>a member of the semaphorin gene family, is up-regulated in pediatric pilocytic astrocytomas (PA) at the mRNA level by microarray analysis and real-time RT-PCR. By further analysis of the expression level of all 17 semaphorin genes in the microarray dataset, we found that <em>Sema5A</em> and <em>Sema3E</em> are the only two semaphorin genes that are highly up-regulated in pilocytic astrocytomas. In this study, the up-regulation of <em>Sema3E</em> was further confirmed by real-time RT-PCR. Furthermore, the over-expression of both SEMA3E and SEMA5A proteins were also confirmed by Western blot analysis and immunohistochemistry. Since pilocytic astrocytoma is characterized by extensive vasculature, co-immunofluorescent staining of both CD31 and SEMA3E (or SEMA5A) was performed. The result showed that a higher expression of SEMA3E was around the CD31 positive endothelial cells. Based on semaphorin’s function in angiogenesis and a higher expression of SEMA3E and SEMA5A around endothelial cells in these PA samples, these genes could be potential biological markers and anti-angiogenesis therapeutic targets for pilocytic astrocytomas.<strong></strong></p>

New Insights on the Effect of Oil Saturation on the Optimal Acid-Injection Rate in Carbonate Acidizing
Authors: Kumar Rahul , He Jia , Bataweel Mohammed , Nasr-El-Din Hisham 
Published: October 2017

Summary
The optimal injection rate for wormhole propagation and face dissolution at low injection rates during carbonate matrix acidizing is well-established. However, little research is documented on the subject of how the presence of oil affects this process. This study demonstrates the impact of oil saturation on wormhole characteristics while acidizing reservoir and outcrop cores under reservoir conditions (200°F).
Coreflood experiments at flow rates ranging from 0.5 to 20 cm3/min were performed to determine the optimal acid-injection rate for wormhole propagation when acidizing homogeneous limestone reservoir cores, low-permeability Indiana limestone cores, and homogeneous dolomite cores with dimensions of a 3- and 6-in. length and a 1.5-in. diameter. The experimental work involved acidizing cores saturated with water, oil, and waterflood residual oil by use of 15-wt% regular hydrochloric acid (HCl). The viscosity of the crude oil used was 3.8 cp at 200°F. Computed-chromatography (CT) scans enabled the characterization of wormholes through the cores. The concentrations of the calcium and magnesium ions in core effluent samples were measured with inductively coupled plasma optical emission spectroscopy (ICP-OES), and the effluent samples were titrated to determine the concentration of the acid.
At injection rates of 0.5 to 20 cm3/min, 15-wt% HCl was effective in creating wormholes with minimal branches for cores with residual oil saturation (ROS). Compared with brine- and oil-saturated cores, those at ROS took less acid volume to breakthrough. In addition, the efficiency of regular acid improved with increased acid-injection rates in the presence of residual oil. A decrease in the acid pore volume (PV) to breakthrough for oil-saturated cores was observed at high acid-injection rates, which could be attributed to viscous fingering of acid through oil. Unlike brine-saturated and oil-saturated cores, cores at ROS showed no face dissolution at low acid-injection rates. The conclusions of this work highlight the impact of oil saturation on matrix characteristics while acidizing carbonate rocks.

Authors: Джанджугазова Елена , Dzhandzhugazova Elena 
Published: October 2017

The article reveals the prospects and reasons for rapid growth of China’s economy; and tourism is an important part of it. It is noted that the accelerated growth of China's GDP contributes to the material welfare of consumers. This, in turn, gives additional development impulses for the domestic consumer market of goods and services, the volumes of which are huge and constantly expanding.
The author considers the Chinese economy as a specific form of a complex but quite organic combination of planned and market economy, which in turn creates the tourist products and services consumption model based on obtaining material wealth, various impressions and experience on the ground of studying Chinese history and the communist traditions of the country. Red Tourism is the material embodiment of this consumption model. It is realized through the red routes, and the Russian Federation has the experience of creating this ones since 2014. Revealing the Red Tourism role and its significance in the system of Russian-Chinese relations, the author focuses on the problems and difficulties of the Red tourism programs development, including due to the lack of consolidated positions of the parties. The results of authoritative statistical and sociological studies and a series of expert assessments form the basis for the analysis given in the article. This makes it possible to propose a whole range of scientific, methodological and practical measures for the development of Red Tourism programs, the most relevant in view of the centennial of the Great October Revolution. The author makes a number of conclusions and recommendations based on personal communication with representatives of the programs high management involved in the Red Tourism development in China during the Forum "Red Way. Bridge of Friendship ", which took place in the border Manchuria (PRC) in July 2017.
Board Independence and the Efficacy of Social Reporting
Authors: Dah Mustafa A. , Jizi Mohammad I. 
Published: October 2017

ABSTRACT
The recent decade of scandals, financial crisis, and loss in moral values questioned the soundness of firms' governance structure and held them more accountable to their societies. This put corporate boards under increased pressure to acknowledge their monitoring needs and respond to societal obligations. This paper offers a deepened understanding of the CSR-firm welfare relationship by suggesting its reliance on the participation of independent directors on corporate boards. Our findings show that higher board independence increases social disclosures. We also show that the effect of social disclosure on the firm's risk and performance is favorably affected by the participation of independent directors on corporate boards. Accordingly, we demonstrate that board independence not only facilitates firms' CSR reporting, but also positively influences the CSR-firm performance association. Board independence enhances the efficacy of CSR reporting by elevating the reliability of the disclosed information and amplifying its signaling power regarding the firm's future prospects. Our empirical evidence supports the U.K. corporate governance code main principles encouraging higher board independence for effective discharge of responsibilities.

Published: October 2017

We developed a new workflow for simulating ion reaction-adsorption-diffusion in nanoporous silica-based materials that are resolved through electron microscopy. Firstly, we propose a matched filtering procedure to identify and segment unique porous regions of the material that will be subject to PDE simulation. Secondly, we perform reaction-adsorption-diffusion PDE simulations on representative material regions that are then applied to characterize the entire microscopy-resolved film surface. Using this model, we examine the capacity of a recently synthesized mesoporous film to tune small molecule permeation through modulating the material permeability, surface chemistryincluding buffering and adsorption, as well as electrolyte composition. Specifically, we find that our proposed matched filtering approach reliably discriminates hexagonal close packed (HCP) porous regions (bulk) from characterized defect regions in transmission electron microscopy (EM) data for nanoporous silica films. Further, based on our implementation of a pH-/surface-chemistry dependent Poisson-Nernst-Planck (PNP) model that is consistent with existing experimental measurements of KCl and CaCl2 conductance, we characterize ion and 5(6)-Carboxyfluorescein (CF) dye permeability in silica-based nanoporous materials over a broad range of ionic strengths, pHs, and surface chemistries. Using this protocol, we probe conditions for selectively tuning small molecule permeability based on mesoporous film pore size, surface charge, ionic strength and surface reactions in the rapid-equilibrium limit.
Information Gatekeepers – Aren't We All? A new perspective for looking at the Human Information Gatekeeper
Authors: Bouhnik Dan , Giat Yahel 
Published: October 2017

In today's knowledge environment, individuals and groups who gather relevant information about the organization's external environment and distribute that information for use by their colleagues, receive increasing attention and are viewed with great importance. These individuals have been named Information Gatekeepers. Thus far, researchers have not established a unanimous and interdisciplinary definition regarding the human information gatekeeper. Nonetheless, a recurrent theme in previous papers regards gatekeepers as a select few throughout the organization. This approach creates two kinds of employees based on a specific set of criteria – those who are gatekeepers and those who are not. The main goal of this research is to examine whether gate keeping is an individual attribute that exists or does not exist within the organization, or whether gate keeping is a continuous attribute that exists within every member and throughout the organization in varying intensity subject to differences in personal characteristics and other factors.

•	Heterogeneity among organizations for higher education hinders co-operation.
•	Information literacy is competing with media literacy.
•	Leadership and responsibility are needed in information literacy education.
•	Developing information literacy training materials requires an adequate budget.
•	Expertise in didactics is also needed for teaching in the area of information literacy.
•	Marketing should support information literacy didactics.
•	Information literacy should be integrated in the curriculum of all students.
•	Libraries should not neglect contemporary information systems.
•	Study materials should be adapted to the upcoming mobile information technology tools.
•	Regional training and workshops on information literacy didactics would be welcome.
•	Data management skills become important besides information literacy.
These challenges should be faced constructively and therefore we formulate for each challenge also a recommendation towards stakeholders.
This paper is based mainly on recent project activities of organizations of higher education in Flanders, Belgium, aimed at
1.	getting a view on the growing expertise in didactics to upgrade the level of information literacy in their region, and paving the way towards more efficient cooperation on information literacy didactics with partner universities, mainly in developing countries,
2.	sharing their experience with universities in developing countries, in Asia, Africa and America, in the form of a fruitful international workshop and follow-up activities.
Teaching Reconsidered: Exploring the Teaching Experiences of Student Affairs Professionals in the College Classroom
Authors: Meraz Lewis Ramona , Jones Boss Ginny , T. McConnell Ayanna 
Published: October 2017

Aim/Purpose	The purpose of this study was to explore the experiences of student affairs professionals who teach in a variety of college classroom settings.

Background	Increasingly, student affairs professionals are serving in teaching roles inside the college classroom; yet, there are few empirical studies that explore that teaching role or the impacts of that teaching experience. Because there are so few studies, we know little of the impacts of these experiences on the individual, the institution, or students.

Methodology	This qualitative study explores the experiences of student affairs professionals who also teach in a variety of campus and classroom settings. The 12 participants from 11 different institutions ranged in years of service in the profession from six to 40 years. They taught an array of undergraduate and graduate courses including first-year experience and career courses, general education courses, and courses in higher education graduate programs. Participants share insights on how their training as student affairs professionals impacts them in their roles as college teachers.

Findings	The findings are categorized into two broad themes: the impacts of practice on teaching and the impacts of teaching on practice. Additionally, participants share how their teaching experiences enhanced their awareness of the academic culture of the academy, enriched their understanding of students, and improved collaborations across their campuses.

Future Research	Our research addresses the gap in the literature by providing a number of considerations on how formal teaching and student affairs practice have a recursive relationship. Future research might explore how teaching at the undergraduate level may differ from teaching at the graduate level. Future research, should explore in what, if any, ways the number of years teaching influences how professionals approach teaching. Future research on teaching might also explore the experiences of student affairs professionals who teach in discipline specific areas.
Understanding Internal Information Systems Security Policy Violations as Paradoxes
Authors: Njenga Kennedy 
Published: October 2017

Aim/Purpose: Violations of Information Systems (IS) security policies continue to generate great anxiety amongst many organizations that use information systems, partly because these violations are carried out by internal employees. This article addresses IS security policy violations in organizational settings, and conceptualizes and problematizes IS security violations by employees of organizations from a paradox perspective.

Background:	The paradox is that internal employees are increasingly being perceived as more of a threat to the security of organizational systems than outsiders. The notion of paradox is exemplified in four organizational contexts of belonging paradox, learning paradox, organizing paradox and performing paradox.

Methodology	: A qualitative conceptual framework exemplifying how IS security violations occur as paradoxes in context to these four areas is presented at the end of this article.

Contribution: The article contributes to IS security management practice and suggests how IS security managers should be positioned to understand violations in light of this paradox perspective.

Findings: The employee generally in the process of carrying out ordinary activities using computing technology exemplifies unique tensions (or paradoxes in belonging, learning, organizing and performing) and these tensions would generally tend to lead to policy violations when an imbalance occurs.

Recommendations for Practitioners: IS security managers must be sensitive to employees tensions.

Future Research:	A quantitative study, where statistical analysis could be applied to generalize findings, could be useful.
Flow-Based Provenance
Authors: Al-Fedaghi Sabah 
Published: October 2017

Aim/Purpose: With information almost effortlessly created and spontaneously available, current progress in Information and Communication Technology (ICT) has led to the complication that information must be scrutinized for trustworthiness and provenance. Information systems must become provenance-aware to be satisfactory in accountability, reproducibility, and trustworthiness of data.

Background:	Multiple models for abstract representation of provenance have been proposed to describe entities, people, and activities involved in producing a piece of data, including the Open Provenance Model (OPM) and the World Wide Web Consortium. These models lack certain concepts necessary for specifying workflows and encoding the provenance of data products used and generated.

Methodology: Without loss of generality, the focus of this paper is on OPM depiction of provenance in terms of a directed graph. We have redrawn several case studies in the framework of our proposed model in order to compare and evaluate it against OPM for representing these cases.

Contribution: This paper offers an alternative flow-based diagrammatic language that can form a foundation for modeling of provenance. The model described here provides an (abstract) machine-like representation of provenance.

Findings: The results suggest a viable alternative in the area of diagrammatic representation for provenance applications.

Future Research: Future work will seek to achieve more accurate comparisons with current models in the field.
