Authors: Tutashkonko S. , Kaminski-Cachopo A. , Boulord C. , Arès R. , Aimez V. , Lemiti M.
Published: May 2011

In this paper we present the results of solar cell’s screen printed contacts thickening by light induced plating (LIP) of Cu and Ag. Light-induced and light-assisted plating techniques are compared. Plating bath current versus illumination intensity, the potentials of metallic anode, front and back surfaces of the solar cell were measured and analyzed for all possible plating modes. The current-voltage behaviour of cells under illumination in a plating bath for the cases of electrically insulated and non-insulated back-surface of a cell is analyzed and discussed. Finally, the exact values of current/voltage/illumination intensity for optimal depositions and a general recipe for their determination for different plating materials are given.

The quality of deposited layers, state of contact-line and anti-reflective coating surface were controlled after plating by cross-section and planar-view SEM observations. The electrical properties of plated contacts and their effect on overall efficiency of solar cell were investigated by measuring contact-line resistance and dark- and light I–V solar cell measurements. The absence of short-circuits was verified by imaging with an infra-red camera.
Exploring What Leads High School Students to Enroll in Hispanic-Serving Institutions
Authors: Núñez Anne-Marie , Bowers Alex J.
Published: May 2011

This study examined the student and high school contextual factors associated with high school students’ enrollment in Hispanic-Serving Institutions (HSIs). The authors drew on a conceptual framework of college choice involving the concepts of multiple capitals and individual and organizational habitus to examine the postsecondary trajectories of high school graduates using the Educational Longitudinal Study 2002/06. Using hierarchical linear modeling, the authors analyzed two separate models. One model predicted enrollment in an HSI within the 2-year sector and one within the 4-year sector. Distinct predictors of HSI versus non-HSI enrollment were found, particularly for the 4-year sector. This study suggests that in both sectors, high school contexts had a significant effect of channeling students toward HSIs.

Microfluidic Mixing: A Review
Authors: Lee Chia-Yen , Chang Chin-Lung , Wang Yao-Nan , Fu Lung-Ming
Published: May 2011

The aim of microfluidic mixing is to achieve a thorough and rapid mixing of multiple samples in microscale devices. In such devices, sample mixing is essentially achieved by enhancing the diffusion effect between the different species flows. Broadly speaking, microfluidic mixing schemes can be categorized as either “active”, where an external energy force is applied to perturb the sample species, or “passive”, where the contact area and contact time of the species samples are increased through specially-designed microchannel configurations. Many mixers have been proposed to facilitate this task over the past 10 years. Accordingly, this paper commences by providing a high level overview of the field of microfluidic mixing devices before describing some of the more significant proposals for active and passive mixers.
In Vitro Antioxidant Activities of Sulfated Derivatives of Polysaccharides Extracted from Auricularia auricular
Authors: Zhang Hua , Wang Zhen-Yu , Yang Lin , Yang Xin , Wang Xue , Zhang Zhi
Published: May 2011

In this research, two types of sulfated polysaccharide derivatives were successfully synthesized. Their antioxidant activities were investigated by employing various established in vitro systems. In addition, the degree of sulfation was evaluated using ion-chromatography and IR spectra. The results verify that, when employing scavenging superoxide radical tests, both the sulfation of acid Auricularia auricular polysaccharides (SAAAP) and the sulfation of neutral Auricularia auricular polysaccharides (SNAAP) derivatives possessed considerable antioxidant activity and had a more powerful antioxidant competence than that of the native non-sulfated polysaccharides (AAAP and NAAP). On the other hand, AAAP and NAAP exhibited stronger activity on scavenging both the hydroxyl radical and lipid peroxidation. Available data obtained with in vitro measurements indicates that the sulfated groups of AAAP and NAAP played an important role on antioxidant activity. In sum, the research demonstrates that the antioxidant activity of sulfated polysaccharide derivatives in vitro has a potential significance for seeking new natural antioxidant protective agents.
Volatile Constituents, Inorganic Elements and Primary Screening of Bioactivity of Black Coral Cigarette Holders
Authors: Bai Xueting , Chen Yicun , Chen Weizhou , Lei Huaping , Shi Ganggang
Published: May 2011

Black corals (BC) have been used for a long time in Chinese medicine, and may have some pharmaceutical functions when used as material for cigarette holders in southeast China. This study is aimed to investigate the bioactivities of volatile constituents in BC and to explore the folklore behind the use of BC cigarette holders (BCCHs). We extracted the volatile constituents of BC by supercritical fluid extraction (SFE) with carbon dioxide (CO2-SFE), then identified and analyzed the constituents by gas chromatography-mass spectrometry (GC-MS). In total, 15 components were reliably identified in BC and found to be biologically active. These included triethyl phosphate, butylated hydroxytoluene, cedrol, n-hexadecanoic acid, squalene, and cholesterol. Meanwhile 13 inorganic elements (P, Ca, Mg, S, B, Si, Fe, Cu, Zn, Ba, etc.) were determined by inductively coupled plasma spectrometer (ICPS). In the bioactivity tests, the BC extract (BCE) showed a scavenging activity of 2,2-diphenyl-1-picrylhydrazyl free radicals and hydroxyl radicals by phenanthroline-Fe (II) oxidation and moderate inhibition of Gram-positive microorganisms. The antioxidant and antimicrobial activities of BC, which are related to the active chemical composition, may explain the perceived benefit for cigarette smokers who use BCCHs.
A New Dual-Frequency Liquid Crystal Lens with Ring-and-Pie Electrodes and a Driving Scheme to Prevent Disclination Lines and Improve Recovery Time
Authors: Kao Yung-Yuan , Chao Paul C.-P.
Published: May 2011

A new liquid crystal lens design is proposed to improve the recovery time with a ring-and-pie electrode pattern through a suitable driving scheme and using dual-frequency liquid crystals (DFLC) MLC-2048. Compared with the conventional single hole-type liquid crystal lens, this new structure of the DFLC lens is composed of only two ITO glasses, one of which is designed with the ring-and-pie pattern. For this device, one can control the orientation of liquid crystal directors via a three-stage switching procedure on the particularly-designed ring-and-pie electrode pattern. This aims to eliminate the disclination lines, and using different drive frequencies to reduce the recovery time to be less than 5 seconds. The proposed DFLC lens is shown effective in reducing recovery time, and then serves well as a potential device in places of the conventional lenses with fixed focus lengths and the conventional LC lens with a single circular-hole electrode pattern.
Infrared Sensor System for Mobile-Robot Positioning in Intelligent Spaces
Authors: Gorostiza Ernesto Martín , Lázaro Galilea José Luis , Meca Meca Franciso Javier , Salido Monzú David , Espinosa Zapata Felipe , Pallarés Puerto Luis
Published: May 2011

The aim of this work was to position a Mobile Robot in an Intelligent Space, and this paper presents a sensorial system for measuring differential phase-shifts in a sinusoidally modulated infrared signal transmitted from the robot. Differential distances were obtained from these phase-shifts, and the position of the robot was estimated by hyperbolic trilateration. Due to the extremely severe trade-off between SNR, angle (coverage) and real-time response, a very accurate design and device selection was required to achieve good precision with wide coverage and acceptable robot speed. An I/Q demodulator was used to measure phases with one-stage synchronous demodulation to DC. A complete set of results from real measurements, both for distance and position estimations, is provided to demonstrate the validity of the system proposed, comparing it with other similar indoor positioning systems.
A Survey on Multimedia-Based Cross-Layer Optimization in Visual Sensor Networks
Authors: Costa Daniel G. , Guedes Luiz Affonso
Published: May 2011

Visual sensor networks (VSNs) comprised of battery-operated electronic devices endowed with low-resolution cameras have expanded the applicability of a series of monitoring applications. Those types of sensors are interconnected by ad hoc error-prone wireless links, imposing stringent restrictions on available bandwidth, end-to-end delay and packet error rates. In such context, multimedia coding is required for data compression and error-resilience, also ensuring energy preservation over the path(s) toward the sink and improving the end-to-end perceptual quality of the received media. Cross-layer optimization may enhance the expected efficiency of VSNs applications, disrupting the conventional information flow of the protocol layers. When the inner characteristics of the multimedia coding techniques are exploited by cross-layer protocols and architectures, higher efficiency may be obtained in visual sensor networks. This paper surveys recent research on multimedia-based cross-layer optimization, presenting the proposed strategies and mechanisms for transmission rate adjustment, congestion control, multipath selection, energy preservation and error recovery. We note that many multimedia-based cross-layer optimization solutions have been proposed in recent years, each one bringing a wealth of contributions to visual sensor networks.
A new family of leafy liverworts from the middle Eocene of Vancouver Island, British Columbia, Canada
Authors: Steenbock Christopher M. , Stockey Ruth A. , Beard Graham , Tomescu Alexandru M. F.
Published: May 2011

•Premise of the study: Morphology is a reflection of evolution, and as the majority of biodiversity that has lived on Earth is now extinct, the study of the fossil record provides a more complete picture of evolution. This study investigates anatomically preserved bryophyte fossils from the Eocene Oyster Bay Formation of Vancouver Island. While the bryophyte fossil record is limited in general, anatomically preserved bryophytes are even more infrequent; thus, the Oyster Bay bryophytes are a particularly significant addition to the bryophyte fossil record.

•Methods: Fossils occur in two marine carbonate nodules collected from the Appian Way locality on the eastern shore of Vancouver Island, British Columbia, and were prepared using the cellulose acetate peel technique.

•Key results: The fossils exhibit a novel combination of characters unknown among extinct and extant liverworts: (1) three‐ranked helical phyllotaxis with underleaves larger than the lateral leaves; (2) fascicled rhizoids associated with the leaves of all three ranks; (3) Anomoclada‐type endogenous branching.

•Conclusions: A new liverwort family, Appianacae fam. nov., is established based upon the novel combination of characters. Appiana gen. nov. broadens the known diversity of bryophytes and adds a hepatic component to one of the richest and best characterized Eocene floras.
An annual pattern of native embolism in upper branches of four tall conifer species
Authors: McCulloh Katherine A. , Johnson Daniel M. , Meinzer Frederick C. , Lachenbruch Barbara
Published: May 2011

• Premise of the study: The Pacific Northwest of North America experiences relatively mild winters and dry summers. For the tall coniferous trees that grow in this region, we predicted that loss in the hydraulic conductivity of uppermost branches would be avoided because of difficulty reversing accumulated emboli in xylem that is always under negative pressure.

• Methods: To test this hypothesis, we measured native percent loss in hydraulic conductivity (PLC; the decrease of in situ hydraulic conductivity relative to the maximum) monthly throughout 2009 in branches at the tops (∼50 m) of four species in an old growth forest in southern Washington.

• Key results: Contrary to our prediction, freeze–thaw cycles resulted in considerable native PLC. Branches showed hydraulic recovery in the spring and after a moderate increase in native embolism that was observed after an unusually hot period in August. The September recovery occurred despite decreases in the leaf and stem water potentials compared to August values.

• Conclusions: Recoveries in branches of these trees could not have occurred by raising the water potential enough to dissolve bubbles simply by transporting water from roots and must have occurred either through water absorption through needles and/or refilling under negative pressure. Excluding the August value, native embolism values correlated strongly with air temperature of the preceding 10 d. For three species, we found that branches with lower wood density had higher specific conductivity, but not greater native PLC than branches with higher wood density, which calls into question whether there is any hydraulic benefit to higher wood density in small branches in those species.
Relationship between Polymorphisms of the Inosine Triphosphatase Gene and Anaemia or Outcome after Treatment with Pegylated Interferon and Ribavirin

Published: May 2011

Background

A genome-wide association study revealed an association between variants of the inosine triphosphatase ( ITPA) gene and ribavirin (RBV)-induced anaemia. The aim of this study was to replicate this finding in an independent Japanese cohort and to define a method to allow pretreatment prediction of anaemia in combination with other factors.

Methods

Genotype 1b chronic hepatitis C patients ( n=132) treated with pegylated interferon (PEG-IFN)-α and RBV for 48 weeks were genotyped for ITPA rs1127354 and examined for anaemia and treatment outcome.

Results

Variants of the ITPA gene protected against severe anaemia throughout the 48-week treatment period and were associated with lower incidence of anaemia-related RBV dose reduction. A combination of the ITPA genotype with baseline haemoglobin (Hb) and creatinine clearance (CLcr) levels predicted severe anaemia with high accuracy (90% sensitivity and 62% specificity). Among a subset of patients with the IL28B genotype of TT at rs8099917, patients with variants of the ITPA gene were associated with a higher rate of receiving >80% of the expected RBV dose, a higher rate of sustained virological response (SVR), and a lower rate of relapse.

Conclusions

The variants of the ITPA gene, which could protect against haemolytic anaemia and RBV dose reduction, were associated with a high rate of SVR by standard PEG-IFN and RBV therapy in a subset of Japanese patients with the favourable TT genotype at rs8099917 of IL28B. A combination of ITPA genetic polymorphisms with baseline Hb and CLcr levels further improves the predictive accuracy of severe anaemia.
Influence of HIV Infection on Cytomegalovirus-Specific Immunity: T-Cell Responses to Pp65 and Ie1 before and after Haart May Refect Altered Cytomegalovirus Biology
Authors: Scherrenburg Jolanda , Schellens Ingrid MM , van Baarle Debbie
Published: May 2011

Background

Data are inconclusive whether treatment with HAART induces functional recovery of HIV-specific T-cells. Since the introduction of HAART, a marked decrease of cytomegalovirus (CMV) disease – for which untreated HIV-infected individuals are at increased risk – is observed, suggesting that this treatment influences CMV-specific T-cell immunity.

Methods

To study potential functional recovery of HIV-and CMV-specific T-cells, CD4+ and CD8+ T-cell responses were measured longitudinally after in vitro expansion using gag, pp65 and IE1 peptide pools, during HIV infection and after long-term HAART.

Results

HIV-specific T-cell function, measured by interferon (IFN)-γ production, was low after initiation of HAART. Interestingly, the cytotoxic function – measured by CD107a expression – of these T-cells temporarily increased after start of treatment, suggesting some functional recovery. The pp65-specific CD8+ T-cell responses tended to decrease during HIV infection, whereas pp65-specific CD4+ T-cell responses decreased upon treatment with HAART. Both pp65-specific CD4+ and CD8+ T-cell responses were low after initiation of HAART compared to healthy controls. By contrast, IE1-specific CD4+ T-cell responses increased during the course of HIV infection. After initiation of HAART, IE1-specific T-cell responses decreased, but IE1-specific CD8+ T-cells seemed increased compared to healthy controls.

Conclusions

This study suggests that HIV-infection leads to an altered CMV biology, affecting pp65- and IE1-specific T-cell responses in a different way, which is not restored by treatment with long-term HAART.
Efficacy and Safety of Nevirapine Extended-Release Once Daily versus Nevirapine Immediate-Release Twice-Daily in Treatment-Naive HIV-1-Infected Patients
Authors: Gathe Joseph , Andrade-Villanueva Jaime , Santiago Steven , Horban Andrzej , Nelson Mark , Cahn Pedro , Bogner Johannes , Spencer David , Podzamczer Daniel , Yong Chan-Loi , Nguyen Thuy , Zhang Wei , Drulak Murray , Quinson Anne-Marie
Published: May 2011

Background

This study (VERxVE) compared the efficacy and safety of the new nevirapine extended-release (NVP XR) formulation dosed once daily with NVP immediate release (IR) twice daily in treatment-naive patients.

Methods

Randomized, double-blind, double-dummy, parallel group study of HIV-1-infected adult patients with baseline viral load (VL) ≥1,000 copies/ml and CD4+ T-cell count of >50-<400 (males) and >50-<250 cells/mm3 (females). Patients stratified by baseline VL (≤100,000/>100,000 copies/ml) were randomized 1:1 to NVP XR 400 mg once daily (plus placebo) or NVP IR 200 mg twice daily (plus placebo), both combined with tenofovir disoproxil fumarate (TDF) 300 mg and emtricitabine 200 mg once daily. Primary endpoint was sustained virological response (<50 copies/ml) through week 48 using the time to loss of virological response algorithm. Non-inferiority of NVP XR to NVP IR was tested using Cochran's statistic incorporating baseline VL stratum with pre- specified, non-inferiority margin of -10%.

Results

Among 1,011 patients randomized and treated, virological response at week 48 was 81.0% (409/505) for NVP XR and 75.9% (384/506) for NVP IR with adjusted difference of 4.9% in favour of NVP XR (95% CI -0.1– 10.0%), demonstrating non-inferiority of NVP XR to NVP IR. This finding was supported by secondary endpoints. The safety profile of NVP XR was similar to NVP IR, but showed numerically fewer treatment-related adverse events.

Conclusions

NVP XR in combination with TDF and emtricitabine was shown to be non-inferior in efficacy to NVP IR with a similar safety and adverse event pro-file, with the potential for the added convenience of once-daily dosing. Trial registration: ClinicalTrials (NCT): NCT00561925.
Les enjeux de la cosmobiologie à la fin de la Renaissance. Juste Lipse et Giordano Bruno
Authors: Paganini Gianni
Published: May 2011

Résumé En identifiant l’âme du monde avec le feu et celui-ci avec Dieu, la représentation stoïcienne du monde comme grand animal doué d’intelligence et de sensibilité pose de graves problèmes à un chrétien, comme le souligne l’interlocuteur du dialogue de la Physiologia Stoicorum de Juste Lipse. Quelle est la position de Lipse par rapport à la question, largement débattue au xvi e siècle, de l’animation des astres ? On évoque les conceptions de Scaliger, Patrizi et Kepler, et on montre que c’est très vraisemblablement Giordano Bruno que Lipse indique sous la forme anonyme « quidam nostro aevo », pour se démarquer de ses positions. Même si la cosmologie de Lipse n’est pas héliocentrique, elle a l’avantage d’expliquer le mouvement des astres sans référence à leur âme et sur la base de considérations purement physiques.

An Assistive Computerized System with Tangible User Interfaces for Children with Moderate Intellectual and Learning Disabilities
Authors: Aljaam Jihad Mohamad , Jaoua Ali , AlHazbi Saleh , Hasnah Ahmad , Karime Ali , A. Elsaddik Abdelmutalib
Published: May 2011

In this paper we propose an assistive learning system for children with moderate intellectual and learning disabilities that supports collaboration, data exploration, communication and creativity. The system offers a wide range of tutorials on basic concepts of elementary sciences with some edutainment games and puzzles based on different tangible user interfaces TUIs. The system can enhance the communications, memorization, reasoning and learning capabilities of the children with special needs. The tutorials contain multimedia elements that help the children understand effectively the topics and allow them to interact and be more proactive. An assessment component is developed to evaluate the children understanding. Parents are actively involved in the learning process by being able to add or customize contents specific to their children. The children can use the TUIs alone and get prompted on all the steps to perform some daily activities like the school day activity, the tooth brushing activity, etc. This will increase their self-reliance and self-dependence.

A Blended Learning Solution and the Impacts on Attendance and Learning Outcomes
Authors: Hakala Ismo , Myllymäki Mikko
Published: May 2011

Blended learning based on lecture videos and face-to-face teaching provides good opportunities for students for participation in education, regardless of time or place. The article describes a blended learning solution that is based on face-to-face teaching and the use of streaming lecture videos as it has developed in connection with master studies in mathematical information technology. The particular focus of this article is on the use of lecture videos and the impacts of blended learning on participation in education and on learning outcomes. According to the results, lecture videos have become very popular among students. Moreover the use of lecture videos increases participation activeness, and the increase in participation has a positive impact on completion of courses. However, the use of lecture videos does not seem to have any clear-cut effect on grades obtained.
Faith and End of Life in Nursing Homes
Authors: Rubinstein Robert L. , Black Helen K. , Doyle Patrick J. , Moss Miriam , Moss Sidney Z.
Published: May 2011

This paper explores the role of religious belief in the experiences of dying and death in a Catholic nursing home. The home appeals to residents and their families due to the active religious presence. Thus, religion is a salient element of the “local culture” which exists in this long-term care setting. The preeminence of faith within the organization and the personal religious convictions of staff, residents, and families may drive how death and dying are discussed and experienced in this setting, as well as the meanings that are attached to them. This paper examines the relationship between faith and the experience and meaning of death in this nursing home. We present themes that emerged from open-ended interviews with residents, family members, and staff, gathered between 1996 and 2004. The data indicate that people select the home due to their Catholic faith and the home's religious tone. Themes also show that belief in God and an afterlife helps shape the experience of dying and death for our informants. Our paper does not compare ease of dying with other nursing homes or within other belief systems.
Cubic Copper Hexacyanoferrates Nanoparticles: Facile Template-Free Deposition and Electrocatalytic Sensing Towards Hydrazine
Authors: Wang Xingxing , Zhang Yun , Jiang Shan , Ji Xiaobo , Liu Yong , Banks Craig E.
Published: May 2011

Cubic copper hexacyanoferrate (CuHCF) nanoparticles prepared via electrolytic deposition are presented with their morphology and crystalline structure characterized with SEM and XRD. The advantage of this methodology is that it allows the fabrication of uniform cubic nanoparticles with permeable structures onto the desired underlying electrode substrate. It was observed that the CuHCF film acts as a permeable membrane for cations such as K+, Na+, Li+, and with a selection order of K+Li+Na+. Furthermore, the analytical utility of these cubic-like CuHCF morphologies supported on a glassy carbon electrode was evaluated towards the electrochemical oxidation of hydrazine which was found to exhibit a linear response over the range 66 M to 17 mM with a detection limit corresponding to 16.5 M.
Acute Childhood Cardiorenal Syndrome and Impact of Cardiovascular Morbidity on Survival
Authors: Olowu Wasiu A.
Published: May 2011

Cardiorenal syndrome (CRS) clinical types, prevalence, aetiology, and acute cardiovascular morbidity impact on the outcome of acute kidney function perturbation were determined. Forty-seven of 101 (46.53%) patients with perturbed kidney function had CRS. Types 3 and 5 CRS were found in 10 and 37 patients, respectively. Type 3 CRS was due to acute glomerulonephritis (AGN; ), captopril (), frusemide (), and hypovolaemia (). Malaria-associated haemoglobinuria (), septicaemia (), lupus nephritis (), tumour lysis syndrome (), and acute lymphoblastic leukaemia () caused Type 5 CRS. The cumulative mortality in hypertensive CRS was similar to nonhypertensive CRS (51.4% versus 40.9%; ). Mortality in CRS and non-CRS was similar (45.7% versus 24.5%; ). Type 5 survived better than type 3 CRS (66.7% versus 12.5%; ). Risk factors for mortality were Type 3 CRS (), AGN-associated CRS (), dialysis requiring CRS (), and heart failure due to causes other than anaemia (). All-cause-mortality was 34.2%. Preventive measures aimed at the preventable CRS aetiologies might be critical to reducing its prevalence.
Stem Cell-Based Approaches for the Treatment of Diabetes
Authors: Kelly Catriona , Flatt Cara C. S. , McClenaghan Neville H.
Published: May 2011

The incidence of diabetes and the associated debilitating complications are increasing at an alarming rate worldwide. Current therapies for type 1 diabetes focus primarily on administration of exogenous insulin to help restore glucose homeostasis. However, such treatment rarely prevents the long-term complications of this serious metabolic disorder, including neuropathy, nephropathy, retinopathy, and cardiovascular disease. Whole pancreas or islet transplantations have enjoyed limited success in some individuals, but these approaches are hampered by the shortage of suitable donors and the burden of lifelong immunosuppression. Here, we review current approaches to differentiate nonislet cell types towards an islet-cell phenotype which may be used for larger-scale cell replacement strategies. In particular, the differentiation protocols used to direct embryonic stem cells, progenitor cells of both endocrine and nonendocrine origin, and induced pluripotent stem cells towards an islet-cell phenotype are discussed.
What Are the bona fide GSK3 Substrates?
Authors: Sutherland Calum
Published: May 2011

Nearly 100 proteins are proposed to be substrates for GSK3, suggesting that this enzyme is a fundamental regulator of almost every process in the cell, in every tissue in the body. However, it is not certain how many of these proposed substrates are regulated by GSK3 in vivo. Clearly, the identification of the physiological functions of GSK3 will be greatly aided by the identification of its bona fide substrates, and the development of GSK3 as a therapeutic target will be highly influenced by this range of actions, hence the need to accurately establish true GSK3 substrates in cells. In this paper the evidence that proposed GSK3 substrates are likely to be physiological targets is assessed, highlighting the key cellular processes that could be modulated by GSK3 activity and inhibition.
Medullary Thyroid Carcinoma: Molecular Signaling Pathways and Emerging Therapies
Authors: Gómez Karen , Varghese Jeena , Jiménez Camilo
Published: May 2011

Research on medullary thyroid carcinoma (MTC) over the last 55 years has led to a good understanding of the genetic defects and altered molecular pathways associated with its development. Currently, with the use of genetic testing, patients at high risk for MTC can be identified before the disease develops and offered prophylactic treatment. In cases of localized neck disease, surgery can be curative. However, once MTC has spread beyond the neck, systemic therapy may be necessary. Conventional chemotherapy has been shown to be ineffective; however, multikinase inhibitors have shown promise in stabilizing disease, and this year will probably see the approval of a drug (Vandetanib) for advanced unresectable or metastatic disease, which represents a new chapter in the history of MTC. In this paper, we explore newly understood molecular pathways and the most promising emerging therapies that may change the management of MTC.
Moving Authentic Soil Research into High School Classrooms: Student Engagement and Learning

Published: May 2011

Inquiry‐based teaching helps students develop a deep, applied understanding of human–environmental connections, but most high school curricula do not use inquiry‐based methods. Soil science topics, which are also generally lacking from curricula, can provide hands‐on model systems for learning inquiry skills. We report on the implementation of a soil science inquiry unit for high school earth science classrooms. Teams in three classes participated in open inquiry about water runoff from, and infiltration into soils. Students learned how scientists conduct research by asking their own research questions, designing and conducting investigations, presenting findings to their peers, and peer‐reviewing each other's work. Student engagement and learning were assessed through testing, final projects, a student survey, and observations of student attitudes. Pre‐ to post‐test gains (17% average gain from 63% average pre‐test score, with 71% maximum gain) showed significant student science‐content‐learning. Generally lower scores on final projects (61% average) than on post‐tests (80% average) suggest the need for more teacher‐scaffolding in complex, open‐ended assignments. Students reported enjoying the unit and learning essential inquiry skills, such as experimental design, scientifically based teamwork and group‐learning, and real world applicability of concepts. Observations suggest that students were motivated and substantively engaged. One‐third of students reported increased excitement about science. We conclude that inquiry‐based units should be more commonly used in science classrooms, to enable students to learn how to think critically, develop collaborative teamwork skills, take ownership of their learning, and be substantively engaged in authentic tasks applicable in later life.

Published: May 2011

Recent National Research Council reports make compelling arguments for the need to incorporate spatial abilities and use spatial technologies throughout our educational system. We conducted a pilot study to determine the pedagogical effectiveness of teaching with geographic information systems (GIS) by using a web‐based GIS tool of Indiana soils. The study was conducted in an undergraduate crop production class over three semesters. We used a pre‐test, treatment, post‐test design in which students (n = 96) were asked a series of questions designed to test their abilities to understand and interpret spatial concepts. During the spring and fall 2009 semesters, traditional assessments with true/false and multiple choice questions were used. After the treatment was administered, the total average score of 68% for the pre‐test increased to 73% for the post‐test with a standard deviation of 13%. However, we concluded that these initial assessments focused on the lower levels of Bloom's Taxonomy. Thus, in the spring 2010 semester we switched to using open concept maps to target higher levels in Bloom's Taxonomy. Using a scoring scheme based on a weighted point system, scores increased from the pre‐concept maps to the post‐concept maps. Paired t‐tests showed that the positive changes that occurred with the treatment were significant (P < 0.01). Overall, a 22% increase in scores for pre‐concept map to post‐concept map reflected a slight increase in instructional learning. The web‐based GIS program received favorable comments from students and proved to be instrumental in providing a rich set of materials that facilitated learner‐centered instruction.
