The influence of online posting dates on the bibliometric indicators of scientific articles
This article analyses the difference in timing between the online
availability of articles and their corresponding print publication and how it
affects two bibliometric indicators: Journal Impact Factor (JIF) and Immediacy
Index. This research examined 18,526 articles, the complete collection of
articles and reviews published by a set of 61 journals on Urology and
Nephrology in 2013 and 2014. The findings suggest that Advance Online
Publication (AOP) accelerates the citation of articles and affects the JIF and
Immediacy Index values. Regarding the JIF values, the comparison between
journals with or without AOP showed statistically significant differences
(P=0.001, Mann-Whitney U test). The Spearman's correlation between the JIF and
the median online-to-print publication delay was not statistically significant.
As to the Immediacy Index, a significant Spearman's correlation (rs=0.280,
P=0.029) was found regarding the median online-to-print publication delays for
journals published in 2014, although no statistically significant correlation
was found for those published in 2013. Most journals examined (n=52 out of 61)
published their articles in AOP. The analysis also showed different publisher
practices: eight journals did not include the online posting dates in the
full-text and nine journals published articles showing two different online
posting dates--the date provided on the journal website and another provided by
Elsevier's Science Direct. These practices suggest the need for transparency
and standardization of the AOP dates of scientific articles for calculating
bibliometric indicators for journals

Protection by Neuroglobin Expression in Brain Pathologies
Astrocytes play an important role in physiological, metabolic, and structural functions, and when impaired, they can be involved in various pathologies including Alzheimer, focal ischemic stroke, and traumatic brain injury. These disorders involve an imbalance in the blood flow and nutrients such as glucose and lactate, leading to biochemical and molecular changes that cause neuronal damage, which is followed by loss of cognitive and motor functions. Previous studies have shown that astrocytes are more resilient than neurons during brain insults as a consequence of their more effective antioxidant systems, transporters, and enzymes, which made them less susceptible to excitotoxicity. In addition, astrocytes synthesize and release different protective molecules for neurons, including neuroglobin, a member of the globin family of proteins. After brain injury, neuroglobin expression is induced in astrocytes. Since neuroglobin promotes neuronal survival, its increased expression in astrocytes after brain injury may represent an endogenous neuroprotective mechanism. Here, we review the role of neuroglobin in the central nervous system, its relationship with different pathologies, and the role of different factors that regulate its expression in astrocytes.GB’s work is supported by Pontificia Universidad Javeriana.Peer reviewedPeer Reviewe
Warehouse management model based on lean manufacturing to reduce the incidence of ceramic tiles breakage in the retail sector
This research analyzed the problem of broken products that negatively affect retail construction finishing companies. For this reason, the study was conducted in a retail company in the mentioned sector. The main problem is broken ceramic tiles found throughout the logistics process. This company has a rate of product breakage of 2.15%, equivalent to 707,704.58 PEN in total cost and costs involved. The leading causes of this problem are poor storage and transportation of products 26.32% and inadequate control and handling of products 27. 03% and poor handling with the forklift 25.97%. A model was formulated under the Lean Manufacturing and warehouse management methodology divided into three stages for the implementation of the tools: "Order and Stability," which consists of the performance of the 5S combined with warehouse management tools, and "Planned Flow," which focuses on the implementation of SLP, and the last phase is called "Make Kaizen Flow" which focuses on the combination of standard work and the Kaizen Philosophy. Finally, through a simulation, it is determined that the application of this model reduces the main problem to 1.65% and allows standardizing activities and improving the order and distribution of the warehouse. This research will be an example for future implementations for companies in the retail sector of construction finishes

California Student Counselors Reflect on a Study Abroad Experience in New Zealand
Seven counseling and guidance students from California participated in a study abroad program in which they were placed in a high school in Auckland, New Zealand, for one month. Their comments on the experience in response to researchers’ questions form the basis of this paper. They suggest that the participants benefited from being immersed in a culturally different context where they had to consider differences in school organization, counseling priorities, and students’ cultural mores. This immersion required them to think about their own professional values and to engage in high level learning, appropriate to masters level field experience work. They commented especially on different approaches to cultural and racial issues in New Zealand and California and on experiencing a counseling profession that is more focused on addressing social issues than on college readiness

Children with acute food protein-induced enterocolitis syndrome from Spain and Italy usually tolerate all other food groups.
Acute food protein-induced enterocolitis syndrome ('FPIES') is a potentially severe type of non IgE-mediated food allergy affecting mainly infants usually when foods are introduced [1]. Acute FPIES triggered by multiple unrelated foods ('multiple food FPIES') has been reported in up to two thirds of patients, particularly in the USA [2,3]. FPIES reactions are often traumatic experiences for parents and weaning leads to significant anxiety, as there is no test to identify safe new foods. This has led to complex weaning recommendations in children with FPIES in an attempt to support parents [4]. However, evidence suggests that multiple food FPIES is rare in other regions, such as Southern Europe [5,6], which questions the applicability of such weaning advice in this population. Studies including a detailed dietary history in children with FPIES are lacking
