 Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105269 Abstract: Background: Today’s nursing profession required to know so much more content and learn it in a much shorter time and stored for a long period until updates and innovations will arrived. The content saturation often seems overwhelming, for both nursing students and faculty. Academic institutions are devising new strategies to meet this challenge; thus, several teaching strategies are being proposed and implemented for this noble purpose. Objective: The study sought to determine the effectiveness of the teaching-learning model of combined jigsaw pedagogy, TBL, and e-Blackboard teaching strategies to improve the academic performance of nursing students of Fakeeh College for Medical Sciences (FCMS). Methods: The study utilized mixed method, and exploratory design of research, which is composed of the quasi-experimental design for the quantitative part and an exploratory descriptive design for the qualitative part of the study. Results: The analysis of variance (ANOVA) between the two groups for both the pretest and post test is conducted. It is worthwhile to note that the pretest results both groups showed “no significant difference” (N = 22; sig. = 0.905) in the scores. But when introduced with different teaching techniques and given posttest, the two groups show “significant difference” (N = 22; sig. = 0.000) in their mean score. This was further supported that the mean score of the experimental group improved significantly. This simply implies that the differentiating methods and additional techniques used show an improvement to the learning of the students. Conclusions: It revealed that Jigsaw as an alternative learning strategy done outside from the traditional learning set up is an effective strategy when tested to nursing students of Fakeeh College of Medical Sciences. The study is in consonance to the claim of other experts that tested Jigsaw in over four decades that it is an effective strategy for learning and developing other skills such as leadership and social engagements. This study suggests proliferating the idea of Jigsaw to other programs of the college as a new dimension of learning.
 Computer Science , 2012, DOI: 10.1214/14-AAP1041 Abstract: We introduce a new kind of percolation on finite graphs called jigsaw percolation. This model attempts to capture networks of people who innovate by merging ideas and who solve problems by piecing together solutions. Each person in a social network has a unique piece of a jigsaw puzzle. Acquainted people with compatible puzzle pieces merge their puzzle pieces. More generally, groups of people with merged puzzle pieces merge if the groups know one another and have a pair of compatible puzzle pieces. The social network solves the puzzle if it eventually merges all the puzzle pieces. For an Erd\H{o}s-R\'{e}nyi social network with $n$ vertices and edge probability $p_n$, we define the critical value $p_c(n)$ for a connected puzzle graph to be the $p_n$ for which the chance of solving the puzzle equals $1/2$. We prove that for the $n$-cycle (ring) puzzle, $p_c(n)=\Theta(1/\log n)$, and for an arbitrary connected puzzle graph with bounded maximum degree, $p_c(n)=O(1/\log n)$ and $\omega(1/n^b)$ for any $b>0$. Surprisingly, with probability tending to 1 as the network size increases to infinity, social networks with a power-law degree distribution cannot solve any bounded-degree puzzle. This model suggests a mechanism for recent empirical claims that innovation increases with social density, and it might begin to show what social networks stifle creativity and what networks collectively innovate.
 Genome Biology , 2011, DOI: 10.1186/gb-2011-12-6-118 Abstract: 'Where do we come from?' 'When did the first humans live?' 'Apparently we're all supposed to be Africans, how is that possible?' These are some of the questions that people ask, and to which a variety of researchers in anthropology, archaeology and genetics try to give reasonable answers. The publication of a revised root for the Y chromosome phylogeny by Scozzari and colleagues [1] now contributes new genetic evidence on the dating and geographical origins of early modern humans.Yes, we do all come from Africa, or, more precisely, the population ancestral to all modern humans lived south of the Sahara Desert, probably around 200 thousand years ago (kya). This conclusion is supported by several approaches, among which the study of modern human genetic variation has played a major role. A key finding is that, among global samples, the highest DNA diversity is found among African populations, and this diversity declines with migration distance from Africa. Furthermore, when 'gene trees' are constructed from sequence variants of particular loci, in most cases the earliest branches are found within African populations.Within the great continent of Africa, however, the details are much less clear. Was there only one ancestral population that expanded from a specific area? If so, where was it? What was its size? Those who study African prehistory know that answers to these questions are much more difficult to find: this is a complex jigsaw puzzle for which the final picture and the number of pieces are still unknown.Recently, a new piece of the puzzle has turned up. In a paper in the American Journal of Human Genetics, Rosaria Scozzari and colleagues present a revised structure for the deepest part of the tree of the male-specific region of the Y chromosome [1]. The novelty of their study is that they took a large-scale sequencing approach, allowing the unbiased ascertainment of many previously undescribed variants. They sequenced 206 kb of Y-chromosomal DNA in seven male
 Barbara Sierman Liber Quarterly : The Journal of European Research Libraries , 2008, Abstract: Before the 22nd Annual Meeting of the Board of Directors of the Foundation CENL, Zagreb, September 24–27, 2008, the author presented a clear overview of the latest developments in digital preservation in a European context. She dealt with organisational aspects, the digital objects themselves, and the effects of international European collaboration. She calls on European organisations such as the Alliance for Permanent Access to sustain the results of temporary projects like PLANETS and thereby bring the pieces of the digital preservation puzzle together. This paper is being published in preparation of the workshop on Curating Research: e-Merging New Roles and Responsibilities in the European Landscape, which is being co-organised by LIBER on 17 April 2009 at the Koninklijke Bibliotheek in The Hague.
 Journal of Asthma and Allergy , 2010, Abstract: Anne-Marie Madore, Catherine LapriseUniversité du Québec à Chicoutimi, Département des sciences fondamentales, Saguenay, CanadaAbstract: Prevalence of allergy and allergic asthma are increasing worldwide. More than half of the US population has a positive skin prick test and approximately 10% are asthmatics. Many studies have been conducted to define immunological pathways underlying allergy and asthma development and to identify the main genetic determinants. In the effort to find missing pieces of the puzzle, new genomic approaches and more standardized ones, such as the candidate gene approach, have been used collectively. This article proposes an overview of the actual knowledge about immunological and genetic aspects of allergy and asthma. Special attention has been drawn to the challenges linked to genetic research in complex traits such as asthma and to the contribution of new genomic approaches.Keywords: immune response, allergy, asthma, genetics, genomics

 International Journal of Soft Computing & Engineering , 2012, Abstract: With an increasing number of automated software bots and automated programs that abuse and corrupt public web services, the user is primarily required to go through and solve a Turing test problem, before they are allowed to use web applications and web services. This Turing test is termed as CAPTCHA.In this paper, JIGSAW puzzle based CAPTCHA (‘JigCaptcha’) is introduced .The paper introduces a drag and drop image based CAPTCHA by integrating image-based CAPTCHA with AJAX and JIGSAW puzzle for the easy access of web services in lesser time.
 Maria J. Briones Frontiers in Environmental Science , 2014, DOI: 10.3389/fenvs.2014.00007 Abstract: Terrestrial ecologists and soil modelers have traditionally portrayed the inhabitants of soil as a black box labeled as "soil fauna" or "decomposers or detritivores” assuming that they just merely recycle the deposited dead plant material. Soil is one of the most diverse habitats on Earth and contains one of the most diverse assemblages of living organisms; however, the opacity of this world has severely limited our understanding of their functional contributions to soil processes and to ecosystem resilience. Traditional taxonomy, based on morphological and anatomical aspects, is becoming replaced by rapid processing molecular techniques (e.g. with marker gene-based approaches). However, this may be impracticable in many ecological studies and consequently, the majority of the current knowledge, still contributes little to our understanding of their role in ecosystem functioning. Over the years, different workers have produced several ‘functional classifications’ based on the body width, feeding regime, certain behavioral and reproductive aspects and ecological niches of soil organisms. Unfortunately, the information available is severely restricted to ‘major’ groups. A better physiological and metabolic understanding of when and how a complex community of soil organisms access nutrients, alter their environment and in turn, affect soil processes, will allow a more realistic quantitative evaluation of their ecological roles in the biogeochemical cycles. Here, I review the applicability of the available approaches, highlight future research challenges and propose a dynamic conceptual framework that could improve our ability to solve this functional puzzle.
 Computer Science , 2004, Abstract: In this paper, we present a novel encryption-less algorithm to enhance security in transmission of data in networks. The algorithm uses an intuitively simple idea of a 'jigsaw puzzle' to break the transformed data into multiple parts where these parts form the pieces of the puzzle. Then these parts are packaged into packets and sent to the receiver. A secure and efficient mechanism is provided to convey the information that is necessary for obtaining the original data at the receiver-end from its parts in the packets, that is, for solving the 'jigsaw puzzle'. The algorithm is designed to provide information-theoretic (that is, unconditional) security by the use of a one-time pad like scheme so that no intermediate or unintended node can obtain the entire data. An authentication code is also used to ensure authenticity of every packet.
