The Importance of Collaborative Groups for the Learning Process

This essay intended to discuss the importance of collaborative groups in the learning process for the preparation of an individual, groups and organization to face the complexity of the new world created by globalization. The methodological approach qualifies as descriptive bibliographical for trying to present features of the phenomena studied linking the different variables and, being a systematic study developed based on published material, from a review of books and articles related to the subject in question, promoting a intersubjective discussion. Based on Senge’s (2006) “learning enterprises” and Morin’s (2006) complexity theories, there were four conclusions: (1) Collaborative groups, unlike work teams, value the individuals that get closer and manipulate their real role in the system, no matter their function, seeing themselves as cause and consequence of processes; (2) The very system must be composed as a “learning” organization in order to motivate collaborative groups to exist; (3) Collaborative groups provides the organization continuous expansion of its capacity to create skills; (4) By creating collaborative groups the system gets intelligent and is able to learn and
Digitalization Adoption in Shipping Business Services. Case study: Libya

In last decade, the increasing number of failing digitalization initiatives is alarming, and the insufficient attention paid to the risks of electronic business (e-business) issues and their management continues to be a key element of these project failures. While number of practical developments in e-business applications is increasing, the increase of implementation processes failures continues to be at an alarming level. This process requires a clear plan to ensure the successful implementation of e-business applications. The study aims is to analyses the necessary progress and steps needed for successful digitalization processes implementation in business organizations. The main scope is the minimization of e-business risk. The approach taken is to identify and minimize the potential risks and to define a strategy of pre-arrangement progress in digitalization projects based on Frank's Model. A unified framework and empirically tested using collected data from field study involved participants from Shipping Service Enterprise in Libya, represented by senior managers in core company management processes. The case findings suggest that people, process and technology dimensions are considered to be the key issues of digitalization adoption in the shipping services sector in Libya. An implementation strategy developed centered on HEEK's model concluded with suggestions as to how digitalization processes can better support e-business management and implementation. The contributions of this paper include the identification and description of critical digitalization barriers and develop an implementation strategy for organizations grounded on the understanding of different roles of key dimensions with strategic alignment role of technology, people and processes.
UNDERSTANDING CFL PRACTICES IN HIGHER EDUCATION IN TERMS OF ACADEMICS’ EDUCATIONAL BELIEFS: ENHANCING REEVES’ ANALYSIS

The research reported here is concerned with the design and use of computer-facilitated learning (CFL) in higher education, and is based on the premise that the educational context in which students learn is heavily influenced by the epistemological and educational assumptions of their academic teachers. The paper reports a preliminary analysis and comparison of two illustrative cases drawn from a larger study in which the beliefs and CFL practices of 24 university academics were studied through intensive interviews supplemented by resource and archival material. The research uses qualitative/ interpretative methods to describe academics’ beliefs about teaching and learning practices. The cases are introduced by narrative descriptions which provide an overview of their salient features and of the connections between beliefs and practices. The cases are then analysed and compared on 12 dimensions some of which were drawn from Reeves, some from an earlier study of ours based on archival materials alone, while others emerged as the research progressed. In addition to its focus on academics’ educational beliefs and practices, the paper briefly considers the advances that have been made over the dimensional framework proposed by Reeves.
Future summer warming pattern under climate change is regulated by lapse-rate changes

Greenhouse gas-driven global temperature change projections exhibit spatial variations, meaning that certain land areas will experience substantially enhanced or reduced surface warming. It is vital to understand enhanced regional warming anomalies as they locally increase heat-related risks to human health and ecosystems. We argue that tropospheric lapse-rate changes play a key role in shaping the future summer warming pattern around the globe in mid-latitudes and the tropics. We present multiple lines of evidence supporting this finding based on idealized simulations over Europe, as well as regional 5 and global climate model ensembles. All simulations consistently show that the vertical distribution of tropospheric summer warming is different in regions characterized by enhanced or reduced surface warming. Enhanced warming is projected where lapse-rate changes are small, implying that the surface and the upper troposphere experience similar warming. On the other hand, strong lapse-rate changes cause a concentration of warming in the upper troposphere and reduced warming near the surface. The varying magnitude of lapse-rate changes is governed by the temperature dependence of the moist-adiabatic lapse 10 rate and the available tropospheric humidity. We conclude that tropospheric temperature changes should be considered along with surface processes when assessing the causes of surface warming patterns.
Brief Idea Title: Effect of PH on Copper hypertolarence: How does the Copper exporters of Staphylococcus aureus are maintaining its functionality within low PH of Phagosome ? Author:

We know that, when any bacterium entered into our body as per the innate immunity phagocytic cells majorly macrophages activated and use copper into phagosome to kill the phagocytized bacterium [1]. Unfortunately most of the bacterium is capable to escaping this due to presence of some genes which code for copper exporters on cell membrane, similarly for Staphylococcus aureus where it code for P1B-1-type ATPase and P1B-3-type ATPase which helped to lower the cytoplasmic copper concentration and enhanced survival [1]. But my question is that how do the ion channels (copper exporters) are functioning well inside of phagosome ? The pH of early and late phagosome and phagolysosome are respectively 6.1–6.5; 5.5–6.0; and 5–5.5 [2] and we know that different pH can alter protein shape, so what is the scenario for those exporters and how does its functioning well? The peptidoglycan barrier can be degraded by Lysozyme [2], so it is possible that the low pH can hamper the bacterium copper efflux efficiency or it is may also possible that they might have any protective mechanism. It is not measured yet so in different pH it can be done.
Task-Oriented Query Classification

In this thesis, we focus on finding the proper task for the user’s submitted query as fast as possible. We presume that a query log categorized by tasks is already available and focus on the problem of finding the right task for a new query. This will help the user accomplishing a search task or fulfilling an information need more satisfying. The main aspects of solving this problem are speed and accuracy. Moreover, we created three different datasets which are publicly available. Two of them have approximately 100,000 queries and the third one contains more than 300,000 queries. These dataset have significantly more queries than available query logs. To find the related task to a query, we experimented 4 methods: (1) Trie data structure to search through queries to find the right task, (2) a hash-based method called Minhash LSH, (3) Word2Vec models and (4) Elastic search. Also we investigated the idea of making pseudo-document from the queries in a task and representing the task with this pseudo-document. The obtained accuracy by Elastic search is higher than other methods. Also, it is a fast method and can define a task in ∼2 milliseconds in the given datasets, which makes it usable in real-time scenarios. We used Word Mover’s Distance(WMD) algorithm to calculate the distance between two queries in Word2Vec models. Word2Vec models are accurate but slow for real-time operations. MinHash LSH, a hash-based method, is faster than Elastic search and Word2vec model, but its accuracy is lower. The analysis of the queries in different datasets shows that there are no distinguishable pattern in these queries that can help us figure out if it is a hard query to find a task for or not.
Modelling and Evaluating Bias in Search Engines

Search engines are a part of everyday life and for many they have become indispensable. However, users often don't realize the in uence search engines can have on the search results they interact with. To analyze this in uence, an approach for assessing bias in search engines is developed in this thesis and then used in an experiment with the search engine Google. The approach focuses on one search engine at a time. It looks at the search results the search engine produces regarding speci c topics, during a de ned time frame, and at a selected location. To calculate the probability of a bias, often asked queries are selected for each topic, and the search results are compared with multiple references, using statistical methods. The references come from di erent sources, most important however is that they include the opinion of society on the topic. The approach is successfully used to asses the bias of Google for nine topics. For two out of the nine topics the ndings show that a bias is likely.
Transparent Woody Film Made by Dissolution of Finely Divided Japanese Beech in Formic Acid at Room Temperature

A new transparent flat woody film was developed by direct dissolution of finely divided Japanese beech wood in formic acid at room temperature for 4−7 days and subsequent slow evaporation of the solvent on a substrate. The obtained woody film was bendable and foldable without breaking (it could be used for origami) and had a relatively high Young’s modulus and tensile strength. The thermal analyses showed that the woody film was mechanically and thermally stable even at relatively high temperatures and can be utilized up to 180 °C without softening. The film absorbed almost the same amount of water as that absorbed by the cellulose film and had very high biodegradability, which was comparable with that of cellulose. The film was prepared without removing any constituents from wood and using a very simple processing method. We think that this work opens the way for the production of biodegradable and sustainable “molded wood” materials.
Evaluation of the Effectiveness of Continuous Venovenous Hemodiafiltration Appli̇ed With Oxiris and AN69 Membranes in Patients With Septic Shock-Related Acute Kidney Injury

Background and objectives: AN69 and Oxiris are filters used in continuous renal replacement therapy. In this study, we aimed to research the effects of these filters on blood cell counts, blood biochemistry, inflammation indicators, clinical status and mortality of patients diagnosed with septic shock-related acute kidney injury. Method: Between March 2019 and October 2019, 42 adult patients (Group 1: Oxiris (n = 21) or Group 2: AN69 (n=21)) with septic shock-related acute kidney injury and received continuous venovenous hemodiafiltration (CVVHDF) in the intensive care unit were included in the study and their results were prospectively observed and compared. The data at the begining of CVVHDF (pre-CVVHDF) and 24 hours after the onset of CVVHDF (post-CVVHDF) were recorded.Results: In the comparison of the pre- and post-CVVHDF values in Group 1, there was a statistically significant decrease detected in the procalcitonin (p = 0.04) and noradrenaline infusion rate (p = 0.02) levels. In terms of the other data there was no statistically significant difference between pre- and post-CVVHDF values in Group 1. In the comparison of the pre- and post-CVVHDF values in Group 2, there was a statistically significant decrease detected in the urea (p = 0.04), platelet count (p = 0.02) and procalcitonin (p = 0.002) levels. There was no statistically significant difference between pre- and post-CVVHDF values in terms of the other data in Group 2. There was no statistically significant difference between the groups in terms of mortality. Conclusions: CVVHDF with Oxiris filter causes a statistically significant decrease in noradrenaline infusion rate. Therefore, we think that the use of CVVHDF with Oxiris filter applied for septic shock-related acute kidney injury will save us time and increase the improvement in the treatment.
Simplified Model of a Grid-Connection Interface Based on Power Electronic Converter for Grid Studies in Dynamic Regime

The paradigm change experienced by worldwide power systems has led to a massive participation of new energy agents: generation, storage, and consumption. In most cases, these agents are equipped with power electronic converters (PEC) to incorporate their energy to the grid. This reality has motivated the development of highly sophisticated and detailed PEC analytical models that accurately represent their dynamics and enable to study their impact on the grid in a simulation environment. However, when it comes to studying large-scale power systems or with all their components disaggregated, the huge computational burden required to simulate a detailed model could make these studies unfeasible. This paper proposes the design of a simplified model of a grid-connection interface based on PEC for power system analysis using MATLAB/Simulink®. The model is designed to represent, with reasonable numerical accuracy, the dynamic behavior of certain electrical variables of interest that would produce a detailed model and, at the same time, to achieve a noticeable reduction in the computation time. A comparative analysis of the numerical results, the dynamics generated, and the convergence time achieved by the two models enable to validate the proposal. These milestones make it possible to fulfill the objectives of this research. El cambio de paradigma experimentado por los sistemas eléctricos a nivel mundial ha propiciado una participación masiva de nuevos agentes energéticos: generación, almacenamiento y consumo. En la mayoría de los casos, estos agentes están dotados de convertidores electrónicos de potencia (CEP) para verter su energía a la red. Esta realidad ha impulsado el desarrollo de modelos analíticos muy sofisticados y detallados de CEP para estudiar el impacto de su interacción con la red en un entorno de simulación. No obstante, cuando se trata de estudiar redes de gran dimensión o con sus componentes desagregados, la enorme carga computacional requerida para simular un modelo detallado podría suponer una limitante para la realización de tales estudios. En este artículo se propone el diseño de un modelo simplificado de una interfaz de conexión a la red basada en CEP, útil para estudios de red mediante MATLAB/Simulink®. El modelo está concebido para representar, con una precisión numérica razonable, el comportamiento dinámico que tendrían ciertas variables eléctricas de interés de un modelo detallado y, al mismo tiempo, para conseguir una reducción significativa del tiempo de cómputo. Un análisis comparativo de los resultados numéricos, las dinámicas generadas y el tiempo de convergencia de los dos modelos permite validar la propuesta. Estos hitos conseguidos permiten cumplimentar los objetivos planteados en esta investigación.
Comparison of prominent methods for computational studies of lanthanoid cation complexation

We compared different computational methods (quantum chemical and DFT) for calculations of binding energies of 8and 9-coordinated lanthanoid–aqua complexes. We used nine computational methods and compared the results with those obtained by the CCSD(T) method. All the nine methods provided relatively similar results and calculated energies correlated very well with the CCSD(T) obtained energies for complexes of this type. The comparison of basis sets revealed that combination of Dolg’s (5s5p4d)/[4s4p3d] + 2s1p1d basis set for lanthanoids and the cc-pvdz basis set for non-lanthanoids can be suggested as optimal for further studies of lanthanoids cation complexation.
Towards a Better Understanding of Mental Models Implied in Sonic Icon Design and Perception

This paper presents our ongoing efforts to determine if there are shared references, i.e. mental models, across designers and potential users of sonic icons in mobile applications. First, 13 sound designer students had to conceive sonic icons regarding 11 common mobile functionalities. Their conceptual models were analyzed through lexical analyses of their self-report on their design and manual annotations of their renderings. Second, the 143 obtained icons were evaluated by 52 naïve listeners through a free categorization task. While deeper analyses are still required, results already indicate that some function/sonic icon links make strong consensus on how they should be realized, considering both the designers’ productions and the listeners’ clustering. This forms one key result of the study and could lead to useful guidelines in sonic icon design.
DETECTION OF TRADITIONAL DAIRY PRODUCTS SOLD I

*Okpo, N.O. , Abdullahi, I.O Federal College of Agricultural Produce Technology, Kano 2,3,4 Department of Microbiology, Ahmadu Bello University, Zaria elendungozi@yahoo.com; 08063910330 ABSTRACT Staphylococcus aureus is one of the most frequent causes of food poisoning (FP). The main etiologic agents of food poisoning are staphylococcal enterotoxins (SEs). Staphylococcal enterotoxins (SEs) are superantigenic toxins. They are five major classical types; SEA, SEB, SEC, SED, SEE, and new SEs or SE SEU. Staphylococcus species implicated in the contamination of milk and milk products were isolated and identified using standard biological methods. Agglutination method was used for phenotypic detection of SE serotypes using the Agglutination (SET-RPLA) kit. The results indicated that out of the 320 milk and milk product sampled, 56 (17.5%) were contaminated by staphylococci. ‘Manshanu’ (cream) were mostly contaminated 22 (6.9%) while the least frequently contaminated was ‘Kindrimo’ 7 (2.2%). Enterotoxin detection revealed that 20 (71.4%) of the S.aureus strains isolated from fresh milk and milk products were enterotoxinogenic. Enterotoxin A serotype were mostly produced least produced 5 (7.1%). The growth of these pathogenic organisms and their toxins in local dairy products indicates poor sanitary practices in the production its products, posing a public health challenge. Hence milk and dairy products may serve as an important means of Staphylococcal food intoxication.

Surgical Management of High Energy Dorsolumbar Fractures

Background: The management of dorsolumbar fractures has been the subject of much controversy. There are different criteria for the choice of management based on the severity of the kyphotic deformity, canal compromise, vertebral height loss, and neurologic status. Objective:To evaluate the results of surgical management of high energy dorsolumbar fractures in the Trauma Unit at Assiut, and at Al-Azhar University Hospitals. Patients and Methods: From October 2017 to October 2019, 40 patients with thoracolumbar spine (TLS) fractures, all of them were treated by posterior instrumentation with pedicle screws and rod system. 23 petients (57.5%) underwent long-segment fixation and 17 patients (42.5%) underwent short-segment fixation. They were operated upon at the Trauma Unit of Assiut University Hospital and Al-Azhar University Hospital. Results:The clinical outcome according to modified Macnab criteria; in long segment group it was excellent in 8 patients (34.7%), good in 11 patients (47.8%), fair in 3 patients (13% ) and poor in 1 patient (4.3%), while in short segment group; it was excellent in 3 (17.6%), good in 10 (58.8%), fair in 3 (17.6%)andpoor in 1 (5.9%). The kyphosis correction (%), in long segment group was ≥70 in 16 patients (70%), <70 in 7 patients (30%), while in short segment group, it was ≥70 in 10 patients (59%) and <70 in 7 patients (41%). Conclusion: Short segment fixation using pedicle screw at the level of fracture, inhigh energy thoracolumbar fractures; provides comparable correction to long segment fixation and the amount of correction loss can be minimized by proper selection of cases suitable for short segment fixation.
What determines the size of contract research from firms to universities? The role of geographical distance and regional co-location

This article explores the role of geographical distance and regional co-location as a determinant of the size of contract research from firms to domestic universities. The analysis relies on a panel of three consecutive R&D surveys for Belgium, and controls for firm, university, and network characteristics. The findings reveal that firms tend to enter into larger-sized contract research with universities that are either located nearby or farther away. Regional co-location is also positively associated with the size of contract research from firms to universities.
