Using Administrative Data for Research on Homelessness: Applying a US Framework to Australia
Authors: Metraux Stephen , Tseng Yi‐Ping
Published: June 2017

The past decade has seen increased use in Australia in the use of administrative data in homelessness research. We review this research, using a framework from the US literature, and highlight innovative and policy‐relevant Australian initiatives in five areas. While the use of administrative data in Australian research on homelessness has lagged behind what has been done in the United States, the emerging body of Australian research in this area should continue to take an increased role in understanding and informing responses to homelessness. We conclude by assessing the opportunities and challenges facing continued research using this type of data.
Empirical Research: Getting Started with Stata
Authors: Tiong Daniel
Published: June 2017

This article provides a guide to approaching empirical research work for the first time, as well as obtaining a foundation in the use of the statistical software package, Stata. The emphasis revolves around data cleaning and its importance in writing a good research essay. I also cover a basic introduction to Stata, the importance of do‐files, common data problems and good coding practice. In closing, I advise that not everything in research needs to go to plan, but that good research practice makes it easier to adapt when plans do not work out.
Sudden Death by Spontaneous Epiglottic Hematoma Secondary to High Blood Levels of Warfarin
Authors: Gilard‐Pioc Séverine , Guerard Pascal , Paraf François , François‐Purssell Irène
Published: June 2017

A 67‐year‐old man was found dead, at his home. On external examination, we found a voluminous purplish black ecchymosis of the anterior neck area. On internal examination, we found a voluminous epiglottis hematoma completely obstructing the upper airway. It was associated with other sites of intra‐abdominal hemorrhage. Toxicological studies revealed the presence of warfarin at a concentration of 8.4 mg/L in peripheral blood, which supposes an INR well above 4.5. To conclude, we supposed death was due to asphyxia secondary to a spontaneous epiglottic hematoma caused by a high blood concentration of warfarin. Hemorrhage in the epiglottis is very rare. To our knowledge, our patient is the only case of “sudden death” reported with spontaneous epiglottic hematoma due to high blood concentration of warfarin. In forensic practice, an anterior neck ecchymosis, without trauma, may suggest hemorrhage into soft airway tissues. Pathology findings make it possible to exclude exogenous trauma.
The use of selective progestin receptor modulators (SPRMs) and more specifically ulipristal acetate in the practice of gynaecology
Authors: Rozenberg Serge , Praet Julie , Pazzaglia Eliza , Gilles Christine , Manigart Yannick , Vandromme Jean
Published: June 2017

This review discusses the development of selective progestin receptor modulators (SPRMs) for use in women's health and specifically the use of ulipristal acetate (UPA) as emergency contraception (EC) and as a treatment for symptomatic fibroids in women who want to preserve their fertility or avoid a hysterectomy. As an EC, UPA 30 mg should be recommended for women, within 102 h of unprotected intercourse. As a treatment of fibroids, UPA (5 mg daily dose) should be administered for periods of three months as a pre‐surgical strategy, reducing bleeding and fibroid size and facilitating surgery. A proportion of these patients may even avoid surgery. Future developments will demonstrate whether UPA can be used for other indications such as endometriosis and breast cancer prevention or treatment.

Published: June 2017

In vitro fermentation and in vivo feeding experiments were conducted to characterize the effects of soybean (Glycine max) husk on the fecal fermentation metabolites and microbiota of dogs. An in vitro fermentation study using feces from three Toy Poodle dogs (6.5 ± 3.5 months in age and 2.9 ± 0.4 kg in body weight) revealed that the fecal inoculum was able to ferment soybean husk (supplemented at 0.01 g/mL culture) and increased levels of short chain fatty acids (SCFA) and Bifidobacterium, irrespective of pre‐digestion of the husk by pepsin and pancreatin. In a feeding experiment, four Shiba dogs (7–48 months in age and 7.5 ± 1.7 kg in body weight) fed a commercial diet supplemented with 5.6% soybean husk showed an increase in SCFA, such as acetate and butyrate, and lactate, and a decrease in indole and skatole in the feces compared to those fed a 5.6% cellulose diet. Real‐time PCR assay showed that soybean husk supplementation stimulated the growth of lactobacilli, Clostridium cluster IV including Faecalibacterium prausnitzii, Clostridium cluster XIVa, Bacteroides‐Prevotella‐Porphyromonas group but inhibited the growth of Clostridium cluster XI. Both in vitro and in vivo experiments indicated that soybean husk supplementation improves gastrointestinal health through optimization of beneficial organic acid production and increase of beneficial bacteria. Therefore, soybean husk is suggested to be applicable as a functional fiber in the formulation of canine diets.

Published: June 2017

Objectives

The combination of clinical psychologists’ therapeutic expertise and research training means that they are in an ideal position to be conducting high‐quality research projects. However, despite these skills and the documented benefits of research to services and service users, research activity in practice remains low. This article aims to give an overview of the advantages of, and difficulties in conducting research in clinical practice.

Method

We reviewed the relevant literature on barriers to research and reflected on our clinical and research experiences in a range of contexts to offer practical recommendations.

Results

We considered factors involved in the planning, sourcing support, implementation, and dissemination phases of research, and outline suggestions to improve the feasibility of research projects in post‐qualification roles.

Conclusions

We suggest that research leadership is particularly important within clinical psychology to ensure the profession's continued visibility and influence within health settings.

Practitioner points

Clinical implications

Emerging evidence suggests that clinical settings that foster research are associated with better patient outcomes.

Suggestions to increase the feasibility of research projects in clinical settings are detailed.

Limitations

The present recommendations are drawn from the authors’ practical experience and may need adaptation to individual practitioners’ settings.

This study does not attempt to assess the efficacy of the strategies suggested.
The Role of Speaker Knowledge in Children's Pragmatic Inferences
Authors: Papafragou Anna , Friedberg Carlyn , Cohen Matthew L.
Published: June 2017

During communication, conversational partners should offer as much information as is required and relevant. For instance, the statement “Some Xs Y” is infelicitous if one knows that all Xs Y. Do children understand the link between speaker knowledge and utterance strength? In Experiment 1, 5‐year‐olds (N = 32) but not 4‐year‐olds (N = 32) reliably connected statements of different logical strength (e.g., “The girl colored all/some of the star”) to observers who were fully or partially informed. Four‐year‐olds’ performance improved when observer knowledge could be assessed more easily (Experiment 2a,N = 25) but remained the same in a nonlinguistic version of Experiment 1 that preserved the epistemic requirements of the original study (Experiment 2b,N = 26). These findings have implications for the development of early communicative abilities.

Published: June 2017

Introduction

CF‐sensing catheter emerged as a novel ablation technology and was increasingly used in clinical practice. Nonetheless, available evidence of efficacy and safety comparison between CF‐guided RF catheter ablation and non‐CF‐guided ablation for treatment of AF was still lacking.

Methods and results

Twenty‐two eligible studies were included after systematic review through the MEDLINE, Google Scholar, the Cochrane Library and PubMed databases. AF/atrial tachycardia‐free survival was markedly improved in CF‐guided catheter ablation compared with non‐CF‐guided ablation at a median 12‐month follow‐up (RR: 1.12, 95% CI: 1.06–1.19, P = 0.000, fixed). Notably, CF‐guided catheter ablation presented a robust survival benefit for treatment of paroxysmal AF (RR: 1.10, 95% CI: 1.03–1.18, P = 0.005, fixed), but not persistent AF (RR: 1.07, 95% CI: 0.89–1.28, P = 0.466, fixed). Moreover, procedure time (WMD: −23.87, 95% CI: −33.83 to −13.91, P = 0.000, random), fluoroscopy time (WMD: −7.78, 95% CI: −13.93 to −1.63, P = 0.013, random) and RF time (WMD: −3.98, 95% CI: −7.78 to −0.17, P = 0.040, random) were significantly reduced in CF‐guided catheter ablation. The incidence of procedure‐related complications did not differ between these two technologies (RR: 0.83, 95% CI: 0.59 to 1.16, P = 0.271, fixed).

Conclusion

CF‐guided RF catheter ablation was associated with a significant AF/atrial tachycardia‐free survival benefit compared with non‐CF‐guided ablation in patients with paroxysmal AF rather than persistent AF. In addition, CF‐guided ablation strategy also reduced the procedure time, fluoroscopy time, as well as RF time despite no distinct effect on the alleviation of procedure‐related complications.
ARE SHORT SELLERS INFORMED? EVIDENCE FROM CREDIT RATING AGENCY ANNOUNCEMENTS
Authors: Shi Jian , Wang Junbo , Zhang Ting
Published: June 2017

Although constrained by rules and regulations, informed short selling (tipping) is present before negative credit watch and certain types of rating downgrade announcements. Using entity credit rating and daily short sale data from April 2004 to December 2009, we find that preannouncement abnormal short selling significantly increases toward the announcement dates and is negatively related to postannouncement stock returns. Furthermore, short selling driven by tipping is more pronounced before more severe and more surprising rating downgrades. This study provides evidence favoring the private information hypothesis (tipping) in the ongoing debate of the informational advantage of short sellers.
Critical Role for Monocytes/Macrophages in Rapid Progression to AIDS in Pediatric Simian Immunodeficiency Virus-Infected Rhesus Macaques

+
T cells in intestinal tissues are major primary target cells for SIV/HIV infection, and massive depletion of these cells is considered a major cause of immunodeficiency. Monocytes and macrophages are important cells of innate immunity and also are targets of HIV/SIV infection. We reported previously that a high peripheral blood monocyte turnover rate was predictive for the onset of disease progression to AIDS in SIV-infected adult macaques. The purpose of this study was to determine if earlier or higher infection of monocytes/macrophages contributes to the more rapid progression to AIDS in infants. We observed that uninfected infant rhesus macaques exhibited higher physiologic baseline monocyte turnover than adults. Early after SIV infection, the monocyte turnover further increased, and it remained high during progression to AIDS. A high percentage of terminal deoxynucleotidyltransferase dUTP nick end label (TUNEL)-positive macrophages in the lymph nodes (LNs) and intestine corresponded with an increasing number of macrophages derived from circulating monocytes (bromodeoxyuridine positive [BrdU
+
] CD163
+
), suggesting that the increased blood monocyte turnover was required to rapidly replenish destroyed tissue macrophages. Immunofluorescence analysis further demonstrated that macrophages were a significant portion of the virus-producing cells found in LNs, intestinal tissues, and lungs. The higher baseline monocyte turnover in infant macaques and subsequent macrophage damage by SIV infection may help explain the basis of more rapid disease progression to AIDS in infants.

IMPORTANCE
HIV infection progresses much more rapidly in pediatric cases than in adults; however, the mechanism for this difference is unclear. Using the rhesus macaque model, this work was performed to address why infants infected with SIV progress more quickly to AIDS than do adults. Earlier we reported that in adult rhesus macaques, increasing monocyte turnover reflected tissue macrophage damage by SIV and was predictive of terminal disease progression to AIDS. Here we report that uninfected infant rhesus macaques exhibited a higher physiological baseline monocyte turnover rate than adults. Furthermore, once infected with SIV, infants displayed further increased monocyte turnover that may have facilitated the accelerated progression to AIDS. These results support a role for monocytes and macrophages in the pathogenesis of SIV/HIV and begin to explain why infants are more prone to rapid disease progression.

Authors: Zhao Xiao-Juan , Hao Hui-Qin
Published: June 2017

In this paper, a semi-discrete coupled nonlinear Schrödinger equation is investigated via the Darboux transformation (DT) method. Based on the Lax pair, the N-fold DT and conservation laws are constructed. Some new discrete soliton solutions under the vanishing and nonvanishing backgrounds are also derived. The dynamic features of those solutions are displayed through figures. The modulation instability (MI) is analyzed and the dispersion relation is derived.
Toggle switch from optical bistability to multistability via an elliptically polarized field
Authors: Yan Xiang-An , Ren Bo-Quan , Wang Li-Qiang , Liu Yao-Wu , Yu Hua-Wa
Published: June 2017

In this paper, we propose a scheme for manipulating the behavior of optical bistability (OB) and optical multistability (OM) in an N-type four-level atomic system. In the scheme, quantum interference is optimized by the left-handed and the right-handed fields of an elliptically polarized field (EPF). The threshold and the hysteresis cycle shape of OB and OM can be controlled by modulating the intensity of the EPF. Especially, the transition from OB to OM or vice versa can also be easily realized by proper tuning the phase difference between the left-handed and right-handed polarized fields under the optimal intensity of the EPF.
Image quality degradation assessment based on the dual-tree complex discrete wavelet transform for evaluating watermarked images
Authors: Omura Hajime , Minamoto Teruya
Published: June 2017

We propose a new image quality degradation assessment method based on the dual-tree complex discrete wavelet transform (DT-CDWT) for evaluating the image quality of watermarked images. The peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) are widely used to evaluate image quality degradation resulting from embedding a digital watermark. The majority of digital image watermarking methods embed a digital watermark in the spatial or frequency domain of an original image. They evaluate image quality degradation using only the spatial domain in spite of the fact that the majority of digital image watermarking methods embed a digital watermark in the spatial or frequency domain. As a result, they do not always fairly evaluate the image quality degradation. Therefore, our method evaluates image quality degradation of the watermarked images using features in the spatial and frequency domains. To extract the features, we defined three indices: 1-norm estimation using bit-planes in the spatial domain, the sharpness, and 1-norm estimation based on the DT-CDWT domains. We describe our image quality assessment method in detail and present experimental results demonstrating that there is a strong positive correlation between the result obtained by our method and a subjective evaluation, in comparison with PSNR and SSIM.
A Dynamic Programming Model for Internal Attack Detection in Wireless Sensor Networks
Authors: Shi Qiong , Qin Li , Song Lipeng , Zhang Rongping , Jia Yanfeng
Published: June 2017

Internal attack is a crucial security problem of WSN (wireless sensor network). In this paper, we focus on the internal attack detection which is an important way to locate attacks. We propose a state transition model, based on the continuous time Markov chain (CTMC), to study the behaviors of the sensors in a WSN under internal attack. Then we conduct the internal attack detection model as the epidemiological model. In this model, we explore the detection rate as the rate of a compromised state transition to a response state. By using the Bellman equation, the utility for the state transitions of a sensor can be written in standard forms of dynamic programming. It reveals a natural way to find the optimal detection rate that is by maximizing the total utility of the compromised state of the node (the sum of current utility and future utility). In particular, we encapsulate the current state, survivability, availability, and energy consumption of the WSN into an information set. We conduct extensive experiments and the results show the effectiveness of our solutions.

Published: June 2017

Oncolytic viruses selectively lyse tumor cells, disrupt immunosuppression within the tumor, and reactivate antitumor immunity, but they have yet to live up to their therapeutic potential. Immune checkpoint modulation has been efficacious in a variety of cancer with an immunogenic microenvironment, but is associated with toxicity due to nonspecific T-cell activation. Therefore, combining these two strategies would likely result in both effective and specific cancer therapy. To test the hypothesis, we first constructed oncolytic adenovirus Delta-24-RGDOX expressing the immune costimulator OX40 ligand (OX40L). Like its predecessor Delta-24-RGD, Delta-24-RGDOX induced immunogenic cell death and recruit lymphocytes to the tumor site. Compared with Delta-24-RGD, Delta-24-RGDOX exhibited superior tumor-specific activation of lymphocytes and proliferation of CD8+ T cells specific to tumor-associated antigens, resulting in cancer-specific immunity. Delta-24-RGDOX mediated more potent antiglioma activity in immunocompetent C57BL/6 but not immunodeficient athymic mice, leading to specific immune memory against the tumor. To further overcome the immune suppression mediated by programmed death-ligand 1 (PD-L1) expression on cancer cells accompanied with virotherapy, intratumoral injection of Delta-24-RGDOX and an anti-PD-L1 antibody showed synergistic inhibition of gliomas and significantly increased survival in mice. Our data demonstrate that combining an oncolytic virus with tumor-targeting immune checkpoint modulators elicits potent in situ autologous cancer vaccination, resulting in an efficacious, tumor-specific, and long-lasting therapeutic effect.

Published: June 2017

The efficiency of current dual antiplatelet therapy might be further improved by its combination with a glycoprotein (GP) VI-targeting strategy without increasing bleeding. GPVI-Fc, a recombinant dimeric fusion protein binding to plaque collagen and concealing binding sites for platelet GPVI, acts as a lesion-focused antiplatelet drug, and does not increase bleeding in vivo. We investigated, whether GPVI-Fc added in vitro on top of acetylsalicylic acid (ASA), the P2Y12 antagonist ticagrelor, and the fibrinogen receptor antagonist abciximab alone or in combination would increase inhibition of platelet activation by atherosclerotic plaque. Under static conditions, GPVI-Fc inhibited plaque-induced platelet aggregation by 53%, and increased platelet inhibition by ASA (51%) and ticagrelor (64%) to 66% and 80%, respectively. Under arterial flow, GPVI-Fc inhibited plaque-induced platelet aggregation by 57%, and significantly increased platelet inhibition by ASA (28%) and ticagrelor (47%) to about 81% each. The triple combination of GPVI-Fc, ASA and ticagrelor achieved almost complete inhibition of plaque-induced platelet aggregation (93%). GPVI-Fc alone or in combination with ASA or ticagrelor did not increase closure time measured by the platelet function analyzer (PFA)-200. GPVI-Fc added on top of abciximab, a clinically used anti-fibrinogen receptor antibody which blocks platelet aggregation, strongly inhibited total (81%) and stable (89%) platelet adhesion. We conclude that GPVI-Fc added on top of single or dual antiplatelet therapy with ASA and/or a P2Y12 antagonist is likely to improve anti-atherothrombotic protection without increasing bleeding risk. In contrast, the strong inhibition of platelet adhesion by GPVI-Fc in combination with GPIIb/IIIa inhibitors could be harmful.

Field Data Analysis and Weather Scenario of a Downburst Event in Livorno, Italy, on 1 October 2012
Authors: Burlando Massimiliano , Romanić Djordje , Solari Giovanni , Hangan Horia , Zhang Shi
Published: June 2017

The Mediterranean is a “hot spot” for the genesis of different types of severe weather events, including potentially damaging wind phenomena like downbursts, whose occurrence and evolution in this geographical region have not been documented in the literature. This paper is part of an interdisciplinary collaboration between atmospheric scientists and wind engineers with the objective of conducting a comprehensive analysis of the field measurements and weather scenarios related to nonsynoptic wind systems in this area. The downburst that struck the Livorno coast of Italy at about 1310 local time 1 October 2012 is investigated as a relevant test case for such severe wind events. The wind velocity records detected by ultrasonic anemometers, part of a monitoring network created for the European “Wind and Ports” and “Wind, Ports and Sea” projects, are analyzed and decomposed in order to inspect the main statistical features of this transient event. The analysis of the meteorological precursors to this event is carried out making use of model analyses, standard in situ measurements, remote sensing techniques, proxy data, and direct observations. The results obtained bring new insights into a downburst’s onset and detection in the Mediterranean, its evolution at the local scale, and possible connections to specific synoptic-scale weather conditions like secondary cyclogenesis in the lee of the Alps.

Published: June 2017

Objectives: Early hyperglycemia is prevalent in preterm infants receiving parenteral nutrition (PN) therapy. Chromium improves glucose tolerance by potentiating the action of insulin. Therefore, we hypothesized that supplementing PN with chromium would improve glucose tolerance and PN calorie delivery in infants during the first week of life. Methods: We collected data on neonates receiving PN initiated at birth with chromium (0.2 mcg/kg/d) started either on days 5–7 (group A) vs day 1 (group B) on PN and compared glucose tolerance and PN calorie administration over the first week of life. Results: For similar mean serum glucose concentrations between group A (n = 348) and B (n = 358) (107 ± 48 vs 111 ± 52 mg/dL, P = .3), infants in group B tolerated higher glucose infusion rates and received more PN calories during the first week of life: 8.4 ± 2 vs 8 ± 2 mg/kg/min (P < .001) and 74.8 ± 23 vs 71.5 ± 12 kcal/kg/d (P = .017), respectively. The difference in calories delivered was more pronounced among very low birth weight (VLBW) infants compared with infants >1500 g: 76.5 ± 14 vs 72.4 ± 11 kcal/kg/d (P = .009) and 73.8 ± 27 vs 70.3 ± 12 kcal/kg/d (P = .079), respectively. Conclusions: PN chromium supplementation resulted in better glucose tolerance and calorie delivery during the first week of life, especially in VLBW infants. This supports chromium’s essential role in enhancing glucose tolerance during PN therapy in VLBW infants at risk for early hyperglycemia.

Door guardian painting is one of the greatest treasures of Chinese art, bearing the weight of the simple feelings and the life awareness of Chinese people. As a specific cultural symbol, door guardian paintings symbolize a kind of popular folkloric culture which has experienced changes under the influence of a changing society. Through door guardian paintings, people’s attitudes and understandings can be observed in their unremitting dreams of a better life. This article begins with the door guardian painting’s tardy development, then discusses its functions and implications in Chinese society. Based on empirical research, this article explores the deep emotional experience expressed in daily life. The uniqueness of the article is that the authors take the function and implication of door guardian paintings as the entry point to explore the development of the rational cognition and mental change of the public in China, and by this to explore the change in people’s daily life so as to inherit and carry forward Chinese culture in the new era.

Resolution enhancement of seismic data using spectral modeling based on dominant Ricker components and separable nonlinear least squares
Authors: Mamasani Mojtaba Gharibi , Manaman Navid Shad , Kazemi Kazem , Mirzakhanian Marzieh
Published: June 2017

Seismic resolution enhancement has a key role in seismic interpretation, especially in reservoir characterization and geologic interpretation. Exploration seismology has a limitation in temporal resolution and thin-layer detection, so any effort to improve the resolution of available data is valuable. Seismic deconvolution is one of the main steps in seismic processing and is intensively used for enhancing the vertical resolution. In this procedure, the seismic wavelet is compressed in order to decrease wavelet interferences and improve temporal resolution. In the common method of seismic deconvolution — i.e., Wiener deconvolution — the seismic wavelet is estimated by using the early part of autocorrelation of traces. Assuming the reflection series is a random function, the smoothed version of the amplitude spectrum of traces can be considered as the amplitude spectrum of the seismic wavelet. The wavelet spectrum can be properly reconstructed by the linear combination of a number of Ricker wavelets with different peak frequencies. The authors aim to introduce a novel method for resolution improvement based on fitting and finding main Ricker components of the source-wavelet spectrum. This attempt is classified under the group of the separable nonlinear least squares (SNLS), the objective function of which is a combination of linear and nonlinear functions. A variable projection method is applied to recognize the optimum peak frequency of Ricker wavelets involved in the wavelet spectrum. Our synthetic tests indicate that the SNLS algorithm is able to achieve a very close approximation of dominant Ricker components of the source spectrum. Considering the minimum phase assumption of the wavelet, the phase spectrum is also computed by Hilbert transform of the estimated amplitude spectrum. Once the amplitude and phase information are available, the deconvolution operator can be designed. Our synthetic and real tests indicate that, in comparison with Wiener deconvolution, spectral modeling based on dominant Ricker components (SMDRC) has improved the deconvolution outputs.

Purpose

The purpose of this study was to review pelvic fractures and concomitant orthopaedic injuries in children who have a patent triradiate cartilage (TRO) compared with children whose triradiate cartilage has closed (TRC). We hypothesise that these injuries will differ, leading to correlated alterations in management.

Patients and Methods

Using a database, we retrospectively reviewed patients aged below 18 years with pelvic fractures presenting to our Level 1 trauma center. Radiographs and CT scans were reviewed to identify orthopaedic injuries and categorise pelvic injuries using the modified Torode classification between the two groups.

Results

A total of 178 patients met inclusion criteria (60 TRO and 118 TRC). Mean age ± SD for TRO and TRC groups were 8 ± 4 years and 16 ± 2 years, respectively. TRO patients were more likely to present as a pedestrian struck by a vehicle (odds ratio (OR) 6.0; p < 0.001) and less likely to present after a motor vehicle collision (OR 0.2; p < 0.001). TRO patients were more likely to sustain rami fractures (OR 2.1; p = 0.020) and Torode IIIA injuries (OR 3.6; p < 0.001). They were less likely to sustain acetabular fractures (OR 0.5; p = 0.042), sacral fractures (OR 0.4; p = 0.009), hip dislocations (p = 0.002) and Torode IV injuries (OR 0.4; p = 0.004). TRO patients were less likely to be treated operatively for their pelvic (OR 0.3; p = 0.013) and orthopaedic injuries (OR 0.4; p = 0.006).

Conclusion

We suggest that patients with open triradiate cartilage are unique. Their pelvic injuries may be treated more conservatively as they have a greater potential for periosteal healing and bone remodelling. Patients with closed triradiate cartilage should be treated similarly to adults, as they share a similar mechanism of injury and need for operative fixation.

Published: June 2017

The aim of this research was to determine the effectiveness of the content-based teaching approach on teaching relational and procedural rules. The research was designed as a single group pretest-posttest pattern which is one of the pre-experimental design. The experimental application was carried out in Eskisehir, Turkey with 241 primary school students whose class was sixth grade. The research data was collected by Information Technologies course achievement test which is used as a pre-test, post-test, recalling test and by the Turkish version of the identifying learning strategies scale. The data was analyzed by means of the independent samples t-test, correlation analysis and regression analysis. The following conclusions were reached based on the data obtained in this research: The content-based teaching approach is an effective approach that can be used in teaching the rules. The content-based teaching, besides being effective while teaching of any rule; compared with procedural rules, it is more effective in teaching the relational rules than the procedural rules. Motivational or emotional learning strategies is an effective variable that predicts the level of rule learning. Compared with all of the learning strategies used by the students, motivational or emotional learning strategies are capable of explaining the level of learning at a rate of 6,3%.

Authors: Karakuş Mehmet , Yeşilpınar Melis
Published: June 2017

The aim of this study was to examine the process of activities and measurment- evaluation in the sixth grade math lesson. In the study that was conducted with case study that is one of the qualitative study patterns. A primary math teacher's lessons were observed, and subsequent to the observations, semi-structured interviews with the teacher and the students were performed. The data obtained from the classroom observations demonstrated that the teacher used different variables so as to increase the quality of teaching service and present the new knowledge to the students, enabled the students to understand and use this knowledge and the teacher exhibited some negative behaviours and produced some negative utterances that influenced the quality of the teaching service. The data pertinent to the students suggested that the students demonstrated learning and thinking products, fulfilled learning needs and made some explanations regarding their performance. However, during the application process it was observed that the teacher was more involved and engaged in the class than the students were and that the acquistion of basic skills specific to the subject accomodated certain limitations. Another dimension during the application and evaluation process of the teacher showed that some difficulties were experienced on account of the stucture and design of the content and physical features of the setting. It was also found that the students had difficulty solving and constructing the problem and learning algebra and that they experienced some difficulties owing to the lack of time while evaluating the process of their learning and that the excessive number of the questions in the evaluation forms caused the students to undergo hard times. The results of the study indicate that an in-service training should be held in order to raise awareness of the teachers so that the students can be more involved in the process of learning. The other difficulties and limitations show that some reformations and reorganizations related to the structure of curriculum and the teaching setting  should be performed.

Published: June 2017

The evaluation of curriculum is significant in terms of curriculum's working and being developed effectively. There are a lot of curriculum evaluation approaches. Recently, one of the most widely accepted paradigms in the field of curriculum evaluation is the opinion that the participants of curriculum are vital for curriculum evaluation. In this study, the views of teachers, who are among the important participants of the curriculum, related to the evaluation of present curriculum and how the evaluation should be carried out were analyzed. In this regard, the aim of this research is analyzing the curriculum evaluation at elementary level in relation with teachers' views. The research being a descriptive study regarding defining a case, is designed according to qualitative method. Accordingly, semi-structured interviews were conducted with determined 11 teachers using critical case sampling and snowball sampling methods. The data was analyzed with descriptive analysis method and presented being supported by direct quotations. As a result of research, it is observed that teachers find the curriculum evaluation activities in our country insufficient. In parallel with the results, the use of Participant-Oriented Evaluation Approach widely in elementary curricula is recommended.

Objective

Brown adipose tissue (BAT) has been proposed as a potential therapeutic target against obesity and its related metabolic conditions. Data from studies in rodents support a cross talk between BAT and other distal tissues. The relation between BAT and peptide hormones secreted from the gastrointestinal system (GI) and involved in appetite regulation is not known in humans.

Design

We studied 18 men during thermoneutral conditions and mild non-shivering cold exposure (CE).

Methods

2-Deoxy-2-(18F)fluoro-d-glucose positron emission tomography-computed tomography scans were conducted after mild cold to measure BAT volume. Fasting serum concentration of GI-secreted peptides and peptides involved in appetite regulation were measured during thermoneutral conditions and mild CE.

Results

During thermoneutral conditions, BAT volume was associated with lower serum concentration of leptin (P = 0.006), gastric inhibitory polypeptide (P = 0.016) and glucagon (P = 0.048) after adjusting for age and body fat percent. CE significantly decreased serum leptin (P = 0.004) and glucagon concentration (P = 0.020), while cold-induced BAT activation was significantly associated with lower serum ghrelin concentration (P = 0.029).

Conclusions

BAT is associated with systemic concentrations of GI-secreted peptides and peptides involved in appetite regulation, suggesting a potential cross talk between BAT and the enteropancreatic axis. Further studies are needed to elucidate the potential link of BAT with the postprandial levels of appetite-regulating peptides and the putative role of BAT in appetite regulation in humans.
El último discurso del presidente Mora (Puntarenas, 17 de setiembre de 1860)
Authors: Abarca Hernández Oriester
Published: June 2017

Se presenta el hallazgo de un discurso, publicado en 1860 por The New York Times y el Panama Star & Herald, que estos atribuyen a Juan Rafael Mora Porras. Afirman tales periódicos que este lo pronunció el 17 de setiembre de 1860, al arribar a la ciudad de Puntarenas. Se examinan algunos argumentos respecto a la plausibilidad de la hipótesis de la autenticidad del discurso de marras y se ofrece una reconstrucción, en castellano, a partir de las dos versiones en inglés.
Acercamientos al grabado
Authors: Hernández Chavarría Francisco
Published: June 2017

El trabajo del grabador inicia con una matriz, en la cual transfiere un diseño, que de acuerdo con la técnica, se graba en una placa de metal, se talla en la madera, se estabiliza en la superficie de una placa de mármol o se pinta en una pantalla de serigrafía bloqueándola selectivamente. Finalmente, esa matriz se impregna en tinta e imprime en papel, tela u otro soporte. Esa imagen impresa es lo que llamamos grabado, con el epíteto otorgado por la matriz, ya sea grabado en metal, xilografía, litografía y serigrafía, respectivamente. El artista decide el número de impresiones que realiza de cada matriz y cada una de esas impresiones es un grabado original y el total se conoce como edición; por eso el grabado se llama el arte del original múltiple.

The first record of Apterichtus kendalli in the Southeast Brazilian Bight is reported based on one leptocephalus collected at around the 100 m isobath during an oceanographic cruise in 1979. It is the southernmost record of this species in the Atlantic. The leptocephalus of A. kendalli was identified based on myomeres counts, fin positions, nine moderate gut swellings, and midline prominent patches of pigments.
Filling the gaps: first record of the Crown-of-thorns Starfish, Acanthaster planci (Linnaeus, 1758) (Spinulosida: Acanthasteridae), at Gorgona Island, Colombia, Tropical Eastern Pacific

Published: June 2017

We report the occurrence of a major corallivore, the Crown-of-thorns Starfish Acanthaster planci, on the coral reefs of Gorgona Island, Tropical Eastern Pacific. Three individuals were sighted on opposite sides of the island, where they fed on small coral colonies of Pavona varians and Pocillopora damicornis. These sightings are noteworthy in light of reports that have demonstrated that the geographic distribution of A. planci is gradually increasing in the equatorial eastern Pacific, particularly south of the Gulf of Chiriquí (Panama) where it was previously absent.
New locality for Lepidosiren paradoxa Fitzinger, 1837 (Dipnoi: Lepidosirenidae) in Argentina
Authors: Vallone Evelyn Romina
Published: June 2017

In this study has document a new locality and thus a southern extension of the distribution of the lungfish Lepidosiren paradoxa to the coast of the Entre Rios Province in the lower Paraná River. This finding increases the range of L. paradoxa by approximately 500 km and represents the third southern record of this species on the south of South America. Additionally, as this region has been relatively well sampled both during past decades and currently, I discuss possible reasons why this range extension has been observed only recently.

Published: June 2017

The Cerrado is the second largest biome of Brazil and one of the most threatened, mainly due to habitat conversion and agricultural expansion. At the same time, the fauna of the Cerrado is poorly known. In this study, undertaken from April to July of 2012, we provide a checklist of the medium-sized to large mammals recorded by camera traps in the Reserva Particular do Patrimônio Natural Serra do Tombador, a private protected area located in northern Goiás state. With a total effort of 2,340 camera-days, we recorded 17 species including rare and threatened species, among them jaguar (Panthera onca), giant armadillo (Priodontes maximus), tapir (Tapirus terrestris) and giant anteater (Myrmecophaga tridactyla). Our results suggest that the surveyed protected area has importance in the conservation of mammals in the Cerrado.

Published: June 2017

This article was migrated. The article was not marked as recommended. Objective: Objective of the study was to compare the jigsaw cooperative learning technique to the traditional lectures for learning cast partial denture designing. Method: Seventy-two fourth BDS students were randomly assigned into either the jigsaw or traditional lecture groups (n = 36). A pre-test on the topic 'designing of cast partial dentures' was administered to all students before the start of the study.The Jigsaw learning method was administered to the experimental group for 4 weeks. At the same time, the control group experienced the lecture-based learning method. At the end of 4 weeks, all students were re-tested (post-test) on the subject. A retention test was administered 3 weeks after the post-test. Mean scores were calculated for each test for the experimental and control groups, and the data obtained was analyzed using independent sample t-test. Results: No significant difference was determined between the jigsaw and lecture-based methods at pre-test. However, post-test and retention scores were better for jigsaw group with statistical significance. The highest mean test score was observed in the post-test with the jigsaw method. In the retention test, success with the jigsaw method was significantly higher than that with the lecture-based method. Conclusion: The jigsaw method can be used as an effective learning tool. However, different topics with varying complexity and different cohorts of students need to be tested in future studies.
