Peer Review system: A Golden standard for publications process

Peer review process helps in evaluating and validating of research that is published in the journals. U.S. Office of Research Integrity reported that data fraudulence was found to be involved in 94% cases of misconduct from 228 identified articles between 1994–2012. If fraud in published article are significantly as high as reported, the question arise in mind, were these articles peer reviewed? Another report said that the reviewers failed to detect 16 cases of fabricated article of Jan Hendrick Schon. Superficial peer reviewing process does not reveals suspicion of misconduct. Lack of knowledge of systemic review process not only demolish the academic integrity in publication but also loss the trust of the people of the institution, the nation, and the world. The aim of this review article is to aware stakeholders specially novice reviewers about the peer review system. Beginners will understand how to review an article and they can justify better action choices in dealing with reviewing an article

Hoping to Help: The Promises and Pitfalls of Global Health Volunteering

Volunteers and the organizations that send them for short periods to poorer countries often describe the trips as “missions” or “brigades.” Both words describe organized, purposeful ventures to accomplish a goal. “Mission” has been used in religious contexts; “brigade” is primarily a military term. In whatever use, both words denote a group with a purpose, a calling, and a common cause. What I am exploring here is the purpose of these missions and brigades and whether these hundreds of weekly arrivals really bring hope (or housing or health benefits) to Haiti or to the thousands of other poor communities around the world that receive international volunteers every year. It may seem obvious that the goal is to accomplish good for the communities visited, to “make a difference,” and often to “give back.” Whether this actually happens, and what other objectives might be involved in these volunteer trips, is rarely considered. These issues motivate this book. Do volunteers help or hurt? In what ways? Can these missions be handled more effectively

Editorial: Surrogacy around the world

Surrogacy is an encouraging management for many childless couples and can hypothetically resolve many unbearable pain that they are confronted. Initially surrogacy treatment was frowned upon, however, surrogacy is more popularly accepted now a day. But different country has different regulations on surrogacy. However, there are some degree of divergence between official discourse and actual practice of surrogacy throughout world. There are positive changes in attitude toward surrogacy has been seen for some countries as well. This editorial brief about surrogacy around the world

Knowledge and attitude of ethics committee (EC) members on bioethics and structure & function of EC in Bangladesh: A pilot study

Having scandalous unethical research practices in the mid and late 20th century, study protocols of biomedical research reviewed by the Ethics Committee (EC) has become the accepted international standard. The Declaration of Helsinki uniformly requires that all biomedical research involving human participants, including research on identifiable human material or data, should be approved by the EC. Today, concerns over the quality of the EC functions worldwide. There are research globally in this regard but no data are available from Bangladesh. Hence, we conducted a questionnaire based pilot study on knowledge and attitude of EC members on bioethics and structure & function of EC in Bangladesh

A search for radio counterparts to Chandra ULX candidates

We present a systematic search for radio counterparts to Ultra Luminous X-ray (ULX) source candidates based on a cross-correlation of the Swartz et al. (2004) ULX catalogue based on Chandra data and the FIRST radio survey. We find seven cases of conspiscuous peaks of radio emission that could be associated to ULX sources. Among these seven ULX radio candidates, three X-ray sources are located within 5" of the FIRST radio peaks. These three cases are shown and discussed individually.Comment: 5 pages, 3 figures.

Low clonal propagation in Atlantic and Mediterranean populations of the red gorgonian Paramuricea clavata (Octocorallia)

Clonal propagation is a common feature of benthic marine organisms. In the present study, we investigated the contribution of clonal reproduction in the red gorgonian Paramuricea clavata. Mediterranean populations of P. clavata were severely affected by mass mortality events caused by increased water temperature in 1999 and 2003. The populations are characterized by slow growth and episodic recruitment, but after the observed mortalities, an unexpectedly high recovery rate was observed in the severely affected populations from the Ligurian Sea, NW Mediterranean. Ten years after the last mortality event, we investigated the contribution of clonal propagation in populations from the Ligurian Sea, where some populations were highly affected by mass mortality events, and from the Atlantic, where mortality was never observed. All individuals were genotyped for nine microsatellite loci. The contribution of clonal reproduction varied from 0% to 13% and did not differ significantly between affected and unaffected populations. We confirm by using genetic markers that clonal propagation in P. clavata is not common, and that the contribution of clones is too low to play an important role in red gorgonian reproduction and cannot contribute to population recovery at sites that have been affected by mass mortality events.Fundacao para a Ciencia e Tecnologia (FCT) under the COMPETE program - European Regional Development Fund [PTDC/BIA-BIC/114526/2009]; MARES Grant; Erasmus Mundus [FPA 2011-0016

CCD BV survey of 42 open clusters

We present results of a photometric survey whose aim was to derive structural and astrophysical parameters for 42 open clusters. While our sample is definitively not representative of the total open cluster sample in the Galaxy, it does cover a wide range of cluster parameters and is uniform enough to allow for simple statistical considerations. BV wide-field CCD photometry was obtained for open clusters for which photometric, structural, and dynamical evolution parameters were determined. The limiting and core radii were determined by analyzing radial density profiles. The ages, reddenings, and distances were obtained from the solar metallicity isochrone fitting. The mass function was used to study the dynamical state of the systems, mass segregation effect and to estimate the total mass and number of cluster members. This study reports on the first determination of basic parameters for 11 out of 42 observed open clusters. The angular sizes for the majority of the observed clusters appear to be several times larger than the catalogue data indicate. The core and limiting cluster radii are correlated and the latter parameter is 3.2 times larger on average. The limiting radius increases with the cluster's mass, and both the limiting and core radii decrease in the course of dynamical evolution. For dynamically not advanced clusters, the mass function slope is similar to the universal IMF slope. For more evolved systems, the effect of evaporation of low-mass members is clearly visible. The initial mass segregation is present in all the observed young clusters, whereas the dynamical mass segregation appears in clusters older than about log(age)=8. Low-mass stars are deficient in the cores of clusters older than log(age)=8.5 and not younger than one relaxation time.Comment: 13 pages, 8 figure

Nothing to hide: An X-ray survey for young stellar objects in the Pipe Nebula

We have previously analyzed sensitive mid-infrared observations to establish that the Pipe Nebula has a very low star-formation efficiency. That study focused on YSOs with excess infrared emission (i.e, protostars and pre-main sequence stars with disks), however, and could have missed a population of more evolved pre-main sequence stars or Class III objects (i.e., young stars with dissipated disks that no longer show excess infrared emission). Evolved pre-main sequence stars are X-ray bright, so we have used ROSAT All-Sky Survey data to search for diskless pre-main sequence stars throughout the Pipe Nebula. We have also analyzed archival XMM-Newton observations of three prominent areas within the Pipe: Barnard 59, containing a known cluster of young stellar objects; Barnard 68, a dense core that has yet to form stars; and the Pipe molecular ring, a high-extinction region in the bowl of the Pipe. We additionally characterize the X-ray properties of YSOs in Barnard 59. The ROSAT and XMM-Newton data provide no indication of a significant population of more evolved pre-main sequence stars within the Pipe, reinforcing our previous measurement of the Pipe's very low star formation efficiency.Comment: Accepted for publication in Ap
