Journal club and post-graduate medical education
Authors: Bhattacharya Surajit 
Published: March 2018

ABSTRACTA journal club is an educational meeting in which a group of individuals discuss published articles, to keep themselves abreast of new knowledge, promoting in them the awareness of current research findings, teaching them to critique and appraise research, and encourage them to utilize research in evidence based practice of the speciality. With so much of market driven research in journals the role of journal club becomes even more vital to differentiate a genuine recent advance from a clever but outright harmful rediscovery of the wheel which has been long discarded. Journal clubs can be department initiated or journal initiated and there are randomized control trials to prove that they improve reading habits, knowledge of epidemiology and statistics, and use of medical literature in practice. Choosing the journal club articles, assessing them and presenting them in the journal club meeting are all of vital importance and as a trainee advances in his training he/she is expected to imbibe the best from his seniors and peers in the club. I a journal club one is simply expected to summarize the research question, the methods, the results and the conclusions and not slavishly read through the article. It is the presenter's interpretation that is more important than actually rehashing the contents of the article.
Exploring revenge as a mediator between bullying and victimisation in gifted and talented students
Authors: Sarıçam Hakan , Çetinkaya Çağdaş 
Published: March 2018

BackgroundGifted children are marked by their unique personal, emotional, and social needs and characteristics as well as their superior abilities. In this context, the aim of study was to explore the relationship between bullying, victimisation, and revenge in gifted students and explain whether or how they are effected by intellectual functioning and gender.Participants and procedureData was obtained from 318 (159 gifted, 159 non-gifted) volunteer secondary school students in Turkey. <i>The Peer Bullying Scale Child Form</i> and <i>Vengeance Scale</i> (VS) were used for data collection. While the data was being analysed, Pearson product moment correlation analysis, stepwise regression analysis, and Multivariate Analysis of Variance (MANOVA) were used because the data provided the criteria for parametric tests.ResultsResearch findings point out that there is a difference statistically between gifted and non-gifted students’ peer bullying, victimisation, and revenge levels. Moreover, revenge was related positively to bullying victims in all students. Mediator revenge partially explains the relationship between victimisation and bullying. On the other hand, findings have shown that victim gifted children have higher revenge levels than do normal peers.ConclusionsBullying is highly connected with retaliation in the study of which children’s opinions on effective strategies to cope with bullying are investigated; taking revenge is accepted as the best way to deal with bullying. Students who bully, their victims, and bystanders are all affected. Bullies can stress all of the people around them, creating a climate of fear and intimidation not only in their victims but also in their fellow students.
Revisiting chlorophyll extraction methods in biological soil crusts – methodology for determination of chlorophyll a and chlorophyll a + b as compared to previous methods

Published: March 2018

Abstract. Chlorophyll concentrations of biological soil crust (biocrust) samples are
commonly determined to quantify the relevance of photosynthetically active
organisms within these surface soil communities. Whereas chlorophyll
extraction methods for freshwater algae and leaf tissues of vascular plants
are well established, there is still some uncertainty regarding the optimal
extraction method for biocrusts, where organism composition is highly
variable and samples comprise major amounts of soil. In this study we
analyzed the efficiency of two different chlorophyll extraction solvents, the
effect of grinding the soil samples prior to the extraction procedure, and
the impact of shaking as an intermediate step during extraction. The analyses
were conducted on four different types of biocrusts. Our results show that
for all biocrust types chlorophyll contents obtained with ethanol were
significantly lower than those obtained using dimethyl sulfoxide (DMSO) as a
solvent. Grinding of biocrust samples prior to analysis caused a highly
significant decrease in chlorophyll content for green algal lichen- and
cyanolichen-dominated biocrusts, and a tendency towards lower values for
moss- and algae-dominated biocrusts. Shaking of the samples after each
extraction step had a significant positive effect on the chlorophyll content
of green algal lichen- and cyanolichen-dominated biocrusts. Based on our
results we confirm a DMSO-based chlorophyll extraction method without
grinding pretreatment and suggest the addition of an intermediate shaking
step for complete chlorophyll extraction (see Supplement S6 for detailed
manual). Determination of a universal chlorophyll extraction method for
biocrusts is essential for the inter-comparability of publications conducted
across all continents.
Sleep Quality in Patients With Rotator Cuff Disease
Authors: Khazzam Michael S. , Mulligan Edward P. , Brunette-Christiansen Meredith , Shirley Zachary 
Published: March 2018

Background:
Little is known about the influence of rotator cuff pathology on sleep. The purpose of this study was to determine which patient-reported factors correlate with sleep disturbance in patients with rotator cuff disease.

Methods:
A nonrandomized, cross-sectional cohort study was performed to evaluate the effects of rotator cuff disease on sleep quality. Data collected at time zero (before any treatment) included the Single Assessment Numeric Evaluation rating, the American Shoulder and Elbow Surgeons score, the Pittsburgh Sleep Quality Index, patient demographics, and medical comorbidities. Statistical analysis included the Pearson correlation and multiple regression analysis to determine which patient-reported factors were associated with sleep disturbance.

Results:
Nocturnal pain was reported by 91% of the 391 participants (274 with tendinitis and 117 with rotator cuff tears). Participants had a mean age of 57 years. Pearson correlation coefficients determined that poor sleep quality in one group or both the tendinitis and the rotator cuff tear groups was associated with higher pain visual analog scale scores (0.27 and 0.31; P = 0.004 and P < 0.0001, respectively), depression (0.27 and 0.30; P < 0.01), female sex (0.24 and 0.27; P < 0.001), presence of low back pain (0.25 and 0.27; P < 0.01), diabetes mellitus (0.24 in the rotator cuff tear group; P < 0.01), and increased body mass index (0.22 and 0.27; P = 0.02).

Discussion:
The status of the rotator cuff did not correlate with increasing symptoms of shoulder pain or with worse sleep quality as measured by the Pittsburgh Sleep Quality Index. These results support the theory that worsening symptoms of shoulder pain may not be clearly associated with rotator cuff disease severity.

Conclusion:
Worse sleep quality scores in patients with rotator cuff disease are associated with pain, depression, female sex, low back pain, diabetes mellitus, and high body mass index. Overall, sleep quality did not differ among patients with varying rotator cuff disease severity. Only hypertension (in patients with rotator cuff tears) and concurrent cervical pathology (in patients with tendinitis) were uniquely related to the disease classification. Further investigation is needed to better define how these factors interact and influence nocturnal shoulder pain and sleep quality in patients with rotator cuff disease.

Current Account and Real Exchange Rate Dynamics in Indonesia
Authors: Mochtar Firman , Affandi Yoga 
Published: March 2018

We analyze the role of both permanent and temporary factors in affecting the Indonesian current account and real exchange dynamics before and after 2000. Adopting Lee and Chinn (1998; 2006) approach as well as Chinn et al. (2007), two results stand out. First, we confirm that the behavior of the real exchange rate has altered since 2000. Identifications show that permanent shocks are the primary causes for the movement of the real exchange rate after 2000, while in the period before 2000, the Indonesian real exchange rate changes are characterized by greater dominance of temporary shocks. The apparent change in the real exchange rate behavior may be strongly justified by the implementation of free-floating exchange rate system since August 1997. Second, the shift of the real exchange rate behavior after 2000 does not necessarily affect the current account dynamics. Empirical evidence confirms that the variance of current account post 2000 remains largely due to temporary shocks. Albeit having increasing influence, permanent shocks have insignificant effect in explaining fluctuations of the current account. In this sense, the current account surplus after 2000 is attributed largely to nominal variables such as price increase, while the impact of productivity improvement is still limited.Keywords: Current Account; Real Exchange Rate; Asian Crises 1997/1998AbstrakKami menganalisa peranan faktor permanen dan temporer dalam memengaruhi neraca berjalan dan dinamika nilai tukar mata uang riil Indonesia sebelum dan setelah tahun 2000. Mengadopsi pendekatan Lee dan Chinn (1998; 2006) serta Chinn et al. (2007), telah diperoleh dua kesimpulan. Pertama, kami mengonfirmasi bahwa pola nilai tukar mata uang riil telah berubah sejak tahun 2000. Identifikasi menunjukkan bahwa shock permanen adalah penyebab utama pergerakan nilai tukar mata uang riil setelah tahun 2000, sedangkan di periode sebelum tahun 2000 perubahan nilai tukar mata uang riil dicirikan oleh dominansi shock temporer. Perubahan pola nilai tukar mata uang tersebut dapat berakar dari penerapan sistem nilai tukar mengambang bebas sejak Agustus 1997. Kedua, perubahan pola nilai tukar mata uang setelah tahun 2000 tidak serta merta memengaruhi dinamika neraca berjalan. Bukti empiris mengonfirmasi bahwa variansi neraca berjalan setelah tahun 2000 tetap disebabkan utamanya oleh shock temporer. Meskipun menunjukkan peningkatan pengaruh, shock permanen memiliki pengaruh yang tidak signifikan dalam menjelaskan fluktuasi neraca berjalan. Atau dalam kata lain, surplus neraca berjalan setelah tahun 2000 dapat diatribusikan kepada variabel nominal seperti kenaikan harga, sedangkan pengaruh peningkatan produktivitas masih cenderung terbatas.Kata kunci: Neraca Transaksi Berjalan; Nilai Tukar Riil; Krisis Asia 1997/1998JEL classifications: F31; F41

Published: March 2018

The main idea of this study is to determine the impact of relative inflation on poverty incidents and to investigate whether inflation inequality has occurred in Indonesia. Interesting results were found at regional level. Firstly, Jakarta had different poverty response with respect to price increases. Processed food and transportation inflation were more imperative for the poor in Jakarta. Secondly, the poor in province with low poverty figures were more prone to inflation. In general, the results show that food inflation has the major adverse impact on the poor. Moreover, we found that inflation in Indonesia has not been pro-poor.AbstrakTujuan utama dari penelitian ini adalah untuk menentukan dampak dari perubahan harga terhadap kemiskinan, serta juga untuk mengetahui apakah terjadi ketimpangan inflasi di Indonesia. Hasil yang menarik diperoleh dari analisa pada tingkat provinsi. Pertama, kemiskinan pada provinsi Jakarta memiliki karakteristik yang berbeda. Inflasi pada makanan jadi dan transportasi justru memiliki dampak yang lebih merugikan masyarakat miskin. Kedua, masyarakat miskin yang berada di provinsi dengan tingkat kemiskinan relatif rendah justru lebih sensitif terhadap inflasi. Secara umum, inflasi bahan makanan merupakan faktor terbesar dalam peningkatan kemiskinan. Selain itu, masyarakat miskin telah mengalami total inflasi yang lebih besar dibandingkan dengan masyarakat tidak miskin.Kata kunci: Kemiskinan; Inflasi; Elastisitas Harga terhadap Kemiskinan; Pro-Poor Price Index; Price Index for the PoorJEL classifications: E3; I3; O1; R2
Middle Class and Democracy: An Assessment on the 2014 Indonesian’s Presidential Election
Authors: Sambodo Maxensius Tri 
Published: March 2018

This paper aims to assess the role of middle class in Indonesia’s democracy, with the particular focus of the last Indonesian Presidential election. This study uses econometric analyses to assess preferences of middle class in presidential election by exploring data at district/city and provincial. The main finding in this study strongly suggests that religious and personality are still important elements under the race of Indonesia president. This study also found that different group of middle class has different attitudes in selecting the presidential candidate and the upper group of middle class is more likely to select Joko Widodo. Finally, a fragile middle class and a relatively high number of abstainers could be a barrier toward more substantive democracy.AbstrakMakalah ini bertujuan untuk menganalisis peran kelompok kelas menengah dalam proses demokrasi di Indonesia, secara khusus peran mereka difokuskan pada hasil pemilihan presiden yang terakhir. Studi ini menggunakan pendekatan ekonometrik untuk mengalisis preferensi kelompok kelas menengah dalam memilih calon presiden, dengan melakukan eksplorasi data pada tingkat kabupaten/kota dan provinsi. Hasil studi menunjukkan, agama dan personalitas calon presiden menjadi faktor penting dalam pertarungan pemilihan presiden. Studi ini juga menunjukkan, berbagai kelompok dalam kelas menengah memiliki preferensi yang berbeda dalam memilih kandidat presiden dan kelompok kelas menengah atas cenderung memilih Joko Widodo. Akhirnya, kelas menengah yang rentan dan tingginya kelompok yang abstain, akan menjadi hambatan untuk menuju demokrasi yang lebih substantif.Kata kunci: Kelas Menengah; Demokrasi; Pemilihan Presiden; IndonesiaJEL classifications: A12; C33
Discharge Estimation in Ungauged Basins Through Variational Data Assimilation: The Potential of the SWOT Mission

Published: March 2018

AbstractSpace‐borne instruments can measure river water surface elevation, slope, and width. Remote sensing of river discharge in ungauged basins is far more challenging, however. This work investigates the estimation of river discharge from simulated observations of the forthcoming Surface Water and Ocean Topography (SWOT) satellite mission using a variant of the classical variational data assimilation method “4D‐Var.” The variational assimilation scheme simultaneously estimates discharge, river bathymetry, and bed roughness in the context of a 1.5 D full Saint‐Venant hydraulic model. Algorithms and procedures are developed to apply the method to fully ungauged basins. The method was tested on the Po and Sacramento Rivers. The SWOT hydrology simulator was used to produce synthetic SWOT observations at each overpass time by simulating the interaction of SWOT radar measurements with the river water surface and nearby land surface topography at a scale of approximately 1 m, thus accounting for layover, thermal noise, and other effects. SWOT data products were synthesized by vectorizing the simulated radar returns, leading to height and width estimates at 200 m increments along the river centerlines. The ingestion of simulated SWOT data generally led to local improvements on prior bathymetry and roughness estimates which allowed the prediction of river discharge at the overpass times with relative root mean squared errors of 12.1% and 11.2% for the Po and Sacramento Rivers, respectively. Nevertheless, equifinality issues that arise from the simultaneous estimation of bed elevation and roughness may prevent their use for different applications, other than discharge estimation through the presented framework.
Cognitive processes underlying the text‐belief consistency effect: An eye‐movement study
Authors: Maier Johanna , Richter Tobias , Britt M. Anne 
Published: March 2018

SummaryReaders' memory for belief‐consistent texts is often stronger than for belief‐inconsistent texts (text‐belief consistency effect). However, presenting belief‐consistent and belief‐inconsistent texts alternatingly reduces the discrepancy between the memory strengths of belief‐consistent and belief‐inconsistent texts. The present study used eye tracking to examine the cognitive processes underlying the text‐belief consistency effect and how it is moderated by the mode of presentation. At 2 points of measurement, 41 university students read 2 belief‐consistent and 2 belief‐inconsistent texts on 2 scientific issues blocked or alternatingly. Comprehension outcomes were assessed with an essay task. First‐pass rereading times were longer for belief‐inconsistent information for participants with strong beliefs. A blocked presentation increased this effect and yielded longer first‐pass rereading times for belief‐inconsistent claims and a text‐belief consistency effect in the essay task. An alternating presentation increased immediate and delayed processing of belief‐inconsistent information and reduced the text‐belief consistency effect, especially in readers making more lookbacks.
Using principles of cognitive science to improve science learning in middle school: What works when and for whom?
Authors: Schunn Christian D. , Newcombe Nora S. , Alfieri Louis , Cromley Jennifer G. , Massey Christine , Merlino Joseph F. 
Published: March 2018

SummaryFour principles of cognitive science were used to make systematic revisions in middle school science instructional modules from two kinds of curriculum: one popular textbook series and one popular hands‐on series (two modules each). Schools were randomly assigned to 1 of the 3 arms (cognitive science modifications with professional development, active control with professional development, or business‐as‐usual). Two cohorts of students were followed in each arm for each setting. There were significant benefits of the cognitive science intervention, but the nature of effects varied for the two settings and curricula. For the text‐based curriculum, positive effects of cognitive science modifications were concentrated in classrooms with lower proportions of underrepresented minority students. For the hands‐on curriculum, there were positive effects that were not linked to school composition. Participation in the active control did not significantly improve student learning. Implications for policy and research are discussed.
An exploration of psychological and physical injury schemas in civil cases
Authors: Vallano Jonathan P. , McQuiston Dawn E. 
Published: March 2018

SummaryCivil plaintiffs often seek compensation for their psychological injuries. Yet little is known about jurors' preconceived notions (or schemas) for a prospective plaintiff's pain and suffering. The present studies examined (a) whether jurors have psychological injury schemas (Studies 1 and 2), (b) whether their existence and development vary by the type of civil case (Studies 1 and 2) or its severity (Study 2), and (c) how psychological injury schemas compare with physical injury schemas on a number of theoretically and legally relevant judgments (e.g., injury severity, availability, and plaintiff credibility; Study 2). Study 1 (N = 233) presented undergraduate mock jurors with 2 negligence incidents (car accident and slip and fall) and 2 intentional tort incidents (sexual assault and kidnapping) and asked them to report the typical incident and injuries that would result from the defendant's conduct. Results supported the sparse existence of psychological injury schemas but found that they were more developed in the kidnapping and sexual assault incidents than in the car accident and slip and fall incidents. Study 2 (N = 288) additionally manipulated incident schema severity (mild vs. severe) while having participants separately report and rate their psychological and physical injury schemas on judgments of legal and theoretical interest. Results indicated that although mock jurors' psychological injury schemas contained fewer injuries than their physical injury schemas, the reported psychological injuries were rated as more severe than physical injuries. We discuss how schemas may underlie the disparate treatment of psychological and physical injuries by legal decision‐makers.
Centrality ratings, forensic relevance, and production frequency: Which one best identifies central and peripheral items?
Authors: Luna Karlos , Albuquerque Pedro B. 
Published: March 2018

SummaryProduction frequency has often been used to identify central and peripheral information, under the assumption that high frequency implies that the item is central. However, no research to date has tested the relationship between centrality and frequency. Participants watched a video of a bank robbery and completed a free recall test, from which frequency for recalled items was computed. Two groups then watched the same video and rated centrality and forensic relevance for each item. Results showed that most, but not all, items with high frequency were rated as central and forensically relevant but that low frequency items were not diagnostic of either item centrality or forensic relevance. Forensic relevance was a better indicator of item centrality than frequency. We concluded that frequency measures should be avoided to determine centrality. Also, if centrality ratings cannot be collected, forensic relevance ratings may be more appropriate for this purpose.
Advances in 3D Bioprinting for Neural Tissue Engineering

Published: March 2018

AbstractCurrent therapies for nerve regeneration within injured tissues have had limited success due to complicated neural anatomy and inhibitory barriers in situ. Recent advancements in 3D bioprinting technologies have enabled researchers to develop novel 3D scaffolds with complex architectures in an effort to mitigate the challenges that beset reliable and defined neural tissue regeneration. Among several possible neuroregenerative treatment approaches that are being explored today, 3D bioprinted scaffolds have the unique advantage of being highly modifiable, which promotes greater resemblance to the native biological architecture of in vivo systems. This high architectural similarity between printed constructs and in vivo structures is thought to facilitate a greater capacity for repair of damaged nerve tissues. In this review, advances of several 3D bioprinting methods are introduced, including laser bioprinting, inkjet bioprinting, and extrusion‐based printing. In addition, the emergence of 4D printing is discussed, which adds a dimension of transformation over time to traditional 3D printing. Finally, an overview of emerging trends in advanced bioprinting materials is provided and their therapeutic potential for application in neural tissue regeneration is evaluated in both the central nervous system and the peripheral nervous system.
