Perceptions of stakeholder groups about the participation of African American family forest landowners in federal landowner assistance programs

This study examines perceptions of three stakeholder groups (African American Family Forest Landowner, Government Agency, and Nonprofit) regarding federal landowner assistance programs in the southern United States by combining a SWOT (strength, weakness, opportunity, and threat) analysis with the AHP (analytical hierarchy process) Factors with the highest priority values were professional advice, lack of staff members, forestland retention, and heirs' property under the SWOT categories of strength, weakness, opportunity, and threat across stakeholder groups, respectively. The guidelines for existing federal landowner assistance programs do not match the needs of African American family forest landowners, especially the mandatory requirements of clear land titles and initial upfront payments. Policy changes coupled with a more targeted and personal outreach approach focusing on capacity building of African American family forest landowners is needed to increase their participation in federal landowner assistance programs.
Research on Key Technologies of Diamond Wire Saw Machining in Hard brittle Material with Ultrasonic Vibration

In the paper, the new process of rotating electroplated diamond wire saw with ultrasonic vibration is used for cutting and machining the typical hard brittle materials like glass and zirconia ceramics to analyze its kinematics, dynamics and other basic theories, moreover, the impact rules of wire saw rotating frequency, lateral pressure, abrasive grain and other process parameters on the machining sawing power and surface roughness are researched based on the experiment. The comparison between normal sawing and ultrasonic sawing in glass indicates that: under the same condition, the tangent saw force of ultrasonic saving is lower than that of normal sawing by 20%~30% and the normal sawing force is decreased when the lateral pressure of workpiece is small (less than 5N) and increased when the lateral pressure is large (5N or above) when the wire saw rotating frequency is 150rpm, the lateral pressure is 2N and the abrasive grain is 280# the machining surface will be given with the best quality with surface roughness of Ra=0.3 0.4mm. Therefore, compared to the surface roughness of Ra=0.8 1.0mm of normal sawing under the same condition, the ultrasonic sawing is superior to the normal sawing by 1 2 levels.

Methods for culturing retinal pigment epithelial cells: a review of current protocols and future recommendations
Venue: Journal of tissue engineering

The retinal pigment epithelium is an important part of the vertebrate eye, particularly in studying the causes and possible treatment of age related macular degeneration. The retinal pigment epithelium is difficult to access in vivo due to its location at the back of the eye, making experimentation with age related macular degeneration treatments problematic. An alternative to in vivo experimentation is cultivating the retinal pigment epithelium in vitro, a practice that has been going on since the 1970s, providing a wide range of retinal pigment epithelial culture protocols, each producing cells and tissue of varying degrees of similarity to natural retinal pigment epithelium. The purpose of this review is to provide researchers with a ready list of retinal pigment epithelial protocols, their effects on cultured tissue, and their specific possible applications. Protocols using human and animal retinal pigment epithelium cells, derived from tissue or cell lines, are discussed, and recommendations for future researchers included.
Antibullying Interventions to Enhance Self Efficacy in Children With Disabilities

Bullying is a serious and widespread issue that plagues schools across the nation. This is particularly true among children with disabilities who are bullied at statistically higher rates and are at an increased risk of being targeted when compared to their peers without disabilities. Despite the severity of this issue, effective counseling interventions and strategies for empowering this population are lacking. To address this gap, this article will introduce an experiential group activity that promotes self efficacy, self determination, and social skills among children with disabilities who experience bullying at school. Considerations and limitations of this activity are discussed.
Implementing the KiVa antibullying program: recognition of stable victims

Teachers do not always recognise students who are victimised by their peers. In this study, we examined the recognition of stable victims in 76 schools beginning to implement the KiVa antibullying programme. We focused on 348 victims (9 15 years) who reported victimisation at the pretest and still at wave 2, after five months of programme implementation. Only 24% of these stable victims received the attention of school personnel during the school year. Multilevel logistic regression analyses revealed that male victims were recognised more often than female victims, but only in elementary school level. Peer reputation as a victim, as well as telling an adult about one's plight increased the likelihood of recognition by school personnel, whereas bullying others (in addition to being victimised) decreased it. The study emphasises the importance of encouraging school personnel to put more effort in reaching the victimised students.
The zinc finger transcription factor PW1/PEG3 restrains murine beta cell cycling
Venue: Diabetologia

hypothesisPw1 or paternally expressed gene 3 (Peg3) encodes a zinc finger transcription factor that is widely expressed during mouse embryonic development and later restricted to multiple somatic stem cell lineages in the adult. The aim of the present study was to define Pw1 expression in the embryonic and adult pancreas and investigate its role in the beta cell cycle in Pw1 wild type and mutant mice.MethodsWe analysed PW1 expression by immunohistochemistry in pancreas of nonpregant and pregnant mice and following injury by partial duct ligation. Its role in the beta cell cycle was studied in vivo using a novel conditional knockout mouse and in vitro by lentivirus mediated gene knockdown.ResultsWe showed that PW1 is expressed in early pancreatic progenitors at E9.5 but becomes progressively restricted to fully differentiated beta cells as they become established after birth and withdraw from the cell cycle. Notably, PW1 expression declines when beta cells are induced to proliferate and loss of PW1 function activates the beta cell cycle. results indicate that PW1 is a co regulator of the beta cell cycle and can thus be considered a novel therapeutic target in diabetes.
Chinese Government Policies and Initiatives on the International Popularization of Chinese: An Economics of Language Perspective

The goal of this chapter is twofold: (1) to introduce the Chinese government's current policies and initiatives for the international popularization of the Chinese language, and (2) to reflect upon the adequacy of the policies and initiatives from the perspective of economics of language. Taking the widely discussed 3 T Issue (i.e. shortages of qualified teachers, appropriate teaching methods, and suitable teaching materials) as an example for analysis, the authors argue that conceptualizing and conducting the international popularization of Chinese as a government led public welfare project, as implicitly assumed in current policies and initiatives, is unlikely to address the issue effectively. Chinese policy makers should consider alternative models and approaches to better facilitate the internationalization of the Chinese language.
Endomorphism fields of abelian varieties

We give a sharp divisibility bound, in terms of g, for the degree of the field extension required to realize the endomorphisms of an abelian variety of dimension g over an arbitrary number field; this refines a result of Silverberg. This follows from a stronger result giving the same bound for the order of the component group of the Sato Tate group of the abelian variety, which had been proved for abelian surfaces by Fite Kedlaya Rotger Sutherland. The proof uses Minkowski's reduction method, but with some care required in the extremal cases when p equals 2 or a Fermat prime.
Phytochemical Analysis and Antiangiogenic Potential of Gmelina Arborea Roxb. (Paper Tree) Fruit Exocarp Using Duck Chorioallantoic Membrane (Cam) Assay

Cancer is one of the leading causes of death in the Philippines and in the world. One of the critical events in the metastasis of cancer is angiogenesis which is the formation of new blood vessels. Prevention of the angiogenesis is necessary for the treatment of such disease. Antiangiogenic chemicals are needed to prevent the growth of blood vessels. Thus, this research would be beneficial to many people since it will pave way to the discovery of new drugs against cancer. The study aimed to evaluate the antiangiogenic property of Gmelina arborea fruit exocarp ethanolic extract (GFEEE) by conducting the Duck Chorioallantoic Membrane (CAM) Assay. The various concentrations of Gmelina ethanolic extracts and the controls were applied on the tenth day of incubation and on the 12 th day, the eggs were subjected to CAM assay. Analysis of Variance revealed that there was a significant difference among all the concentrations in terms of percentage CAM vascularity inhibition as compared to the positive control. However, among all the concentrations, 100% concentration of GFEEE has the highest percentage CAM vascularity inhibition. However, using Tukey's Multiple Comparison Tests indicated that there was no significant difference in the percentage vascular inhibition between 75% and 100% concentration which implies that those concentrations have the same antiangiogenic effect. Moreover, the active constituents present in Gmelina fruit exocarp indicates that the results of the present study has a clinical effect and can be a potential source of natural antiangiogenic agents that can be possibly used as anti tumoral agent and can lead to probable settling of the issue of expensive anticarciongenic drugs.
Detecting object affordances with Convolutional Neural Networks
Venue: 2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)

We present a novel and real time method to detect object affordances from RGB D images. Our method trains a deep Convolutional Neural Network (CNN) to learn deep features from the input data in an end to end manner. The CNN has an encoder decoder architecture in order to obtain smooth label predictions. The input data are represented as multiple modalities to let the network learn the features more effectively. Our method sets a new benchmark on detecting object affordances, improving the accuracy by 20% in comparison with the state of the art methods that use hand designed geometric features. Furthermore, we apply our detection method on a full size humanoid robot (WALK MAN) to demonstrate that the robot is able to perform grasps after efficiently detecting the object affordances.
Competing Against Luck: The Story of Innovation and Customer Choice

The foremost authority on innovation and growth presents a path breaking book every company needs to transform innovation from a game of chance to one in which they develop products and services customers not only want to buy, but are willing to pay premium prices for. How do companies know how to grow? How can they create products that they are sure customers want to buy? Can innovation be more than a game of hit and miss? Harvard Business School professor Clayton Christensen has the answer. A generation ago, Christensen revolutionized business with his groundbreaking theory of disruptive innovation. Now, he goes further, offering powerful new insights. After years of research, Christensen and his co authors have come to one critical conclusion: our long held maxim that understanding the customer is the crux of innovation is wrong. Customers don't buy products or services; they "hire" them to do a job. Understanding customers does not drive innovation success, he argues. Understanding customer jobs does. The "Jobs to Be Done" approach can be seen in some of the world's most respected companies and fast growing startups, including Amazon, Intuit, Uber, Airbnb, and Chobani yogurt, to name just a few. But this book is not about celebrating these successes it's about predicting new ones. Christensen, Hall, Dillon, and Duncan contend that by understanding what causes customers to "hire" a product or service, any business can improve its innovation track record, creating products that customers not only want to hire, but that they'll pay premium prices to bring into their lives. Jobs theory offers new hope for growth to companies frustrated by their hit and miss efforts. This book carefully lays down the authors' provocative framework, providing a comprehensive explanation of the theory and why it is predictive, how to use it in the real world and, most importantly, how not to squander the insights it provides.
Factors associating the IT capability in healthcare services and its perceived transformation impact
Venue: Int. J. Bus. Inf. Syst.

Healthcare providers in Malaysia are facing the challenges linking clinical administrative processes to ensure that an effective collaboration and efficient delivery of care are in place. The challenge is influenced by the state of the current health information technology HIT infrastructure and hospital information and management systems HIMS deployed across hospitals in Malaysia that are typically confined within a particular healthcare provider without any sort of sharing and integration across other healthcare service providers and its associates. With these challenges identified, the study attempts to examine the factors associating the perceived transformation impact within the context of the healthcare sector in Malaysia. The findings of this study involves a survey being carried out with a total 564 participant's with the responses being screened with IBM SPSS 20.0. Structural equation modelling SEM using AMOS 20.0 was adopted to test all latent factors of the research model and it resulted in a relatively good fit. The overall empirical findings as a result from this study suggests that healthcare providers can be relieved supporting complex in house IT infrastructures by leveraging on the proposed private cloud national health information exchange.
Integrating contextual and online self reported data for personalized healthcare: a tennis elbow case study

Advances in sensors and mobile technology have helped evolve the use of eHealth, especially in the field of chronic pain. Chronic pain is a widespread problem where self management is important. Current studies tend to collect data at sparse intervals due to the cost involved in collecting data using traditional instruments. We demonstrate how technology enables richer data collection frequencies to analyse the influence of patients' context on their pain levels. In this paper, we present a case study as an add on analysis to a clinical trial for lateral epicondylitis (tennis elbow) We explore the usefulness of on line key data collected at higher frequencies in explaining or discovering changes in pain. This dataset allowed us to learn that there are no associations with temperature and humidity to this type of pain, that patients tend to have different pain experiences, and that pain at night tends to be higher than overall or activity related pain.
Acupuncture Treatment of Lateral Elbow Pain: A Nonrandomized Pilot Study
Venue: Evidence based complementary and alternative medicine eCAM

In planning for a large scale multicenter trial to evaluate the effect of acupuncture for the treatment of lateral elbow pain, a pilot study was conducted. This was a prospective, investigator and patient blinded, nonrandomized, placebo controlled trial. Subjects were evaluated at baseline, before fourth, seventh, and ninth treatment, and at a two week posttreatment follow up. The treatment group received unilateral acupuncture at LI 10 and LI 11 at the affected side with manual needle manipulation; the control group received sham laser acupuncture at the same acupoints. Measures included (i) disabilities of the arm, shoulder, and hand (DASH) questionnaire, (ii) pain free grip strength (PFGS) and (iii) a visual analogue scale (VAS) for pain. Significant differences in DASH score, PFGS, and VAS between treatment and control group were found at the ninth treatment (n 20 for each group, P 0.05) Only DASH showed significant differences compared to the control for all the measurement time points after treatment commenced and appears to be a sensitive and appropriate primary outcome measure for the future multisite trial. Results from this pilot study provided relevant information about treatment efficacy, credibility of control treatment, and sensitivity of different outcome measures for the planning of the future trial.

Data rate optimization on PLC devices with current controller for low access impedance
Venue: 2016 International Symposium on Power Line Communications and its Applications (ISPLC)

Access impedance of power line channel is mostly frequency dependent. PLC devices manufactures determine the transmitted signal on the electrical power grid as voltage, based on EN50065 1. However, the transmitted signal (voltage) often does not reach the specified signal in EN50065 1 because of the energy efficiency rules of PLC devices. The power consumption limitation of PLC devices is realized by reduction on the power amplifier (PA) output voltage level. The PA output reduction is implemented by current regulator based on current measurement. As a consequence of the PA output level reduction, the transmitted signal reduces at the transmitter and receiver side which reduce the performance of the PLC systems and the data rate as well. In this paper we present the effect of the access impedance by reducing the data rate of PLC systems. In our simulation, we find the achievable data rate considering access impedance values related to EN50065 1 and measurements done in China and Austria. We introduce optimization algorithms to improve the achievable data rate by disabling subcarriers in frequencies with low access impedance which increases automatically the signal on the other subcarriers with sufficient access impedance. These algorithms can be combined with most of PLC standards since the modification on the transmitted signal is only produced from the PLC channel and the receiver should be able under specific constraints to handle these changes.
A diagnostic method for power line networks by channel estimation of PLC devices
Venue: 2016 IEEE International Conference on Smart Grid Communications (SmartGridComm)

Cost efficiency and supply reliability are of major interest for power grids and networks. Therefore, we introduce a novel approach for power line diagnostics using channel measurements of power line communication devices. This approach does not require the test subject to be taken out of service. Periodic channel measurements provide insight into possible quality degradations of the cable as well as information to locate a degradation. A proof of concept is provided via simulation for a point to point connection of two power line devices. We show to which extent reliable information can be obtained for the test subject and investigate the influence of various parameters.
