Web Content Management Systems, a Collaborative Environment in the Information Society

The aim of the present paper is to analyze the main models of collaboration and the use of a Web CMS, in order to develop an online community. Taking into consideration the multitude of the existing Web CMSs on the market and their diverse functionalities, we conducted a prospective study that tests the development trends in the field, with the view of finding out which are the most important Web CMSs in practice, and which are the most important functionalities they have to possess, in order to develop a collaborative online community. The results of the study show that the most popular Web CMS is Joomla, and the most widespread programming language is PHP. Likewise, we consider that this study can help the entry-level web developers to get an overview of the most popular Web CMSs, and their functionalities.collaboration, content management, web content management systems

THE CHANGING ROLE OF ACCOUNTANTS IN A TRANSITION ECONOMY – EVIDENCE FROM ROMANIA

Recently a number of interventions have impacted the Romanianaccounting system, such as the harmonization with the European Directives,International Financial Reporting Standards (IFRS), and an increased move towardsmodern information technologies such as Enterprise Resource Planning (ERP)software. In this study we directly explore these influences by applying job offeranalysis as a reflection of current and future organizational practices (Bollecker,2000). We determine the competencies expected from accountants in Romanianbusinesses and ask whether financial accounting and management accounting areseparate specialized positions in Romania, or are they developing into hybrid monistpositions? We conclude that the state of the Romanian accounting profession is one oftransition with some alignment with recent global trends. However, our inter-temporal analysis also suggests a degree of intransience with management andfinancial accountants, whilst sharing some common competencies, still maintaining anumber of attributes associated with the two-cycle accounting system. Finally, weshow that ERP competencies are the more important drivers of the hybridization ofaccountants in Romania.accountants in transition, hybridization of accounting roles, Romanian accountingprofession, two-cycle accounting system, enterprise resource planning, job-offer analysis

Understanding Patterns of Deep Learning ModelEvolution in Network Architecture Search

Network Architecture Search and specifically Regularized Evolution is a common way to refine the structure of a deep learning model.However, little is known about how models empirically evolve over time which has design implications for designing caching policies, refining the search algorithm for particular applications, and other important use cases.In this work, we algorithmically analyze and quantitatively characterize the patterns of model evolution for a set of models from the Candle project and the Nasbench-201 search space.We show how the evolution of the model structure is influenced by the regularized evolution algorithm. We describe how evolutionary patterns appear in distributed settings and opportunities for caching and improved scheduling. Lastly, we describe the conditions that affect when particular model architectures rise and fall in popularity based on their frequency of acting as a donor in a sliding window.Comment: 11 pages, 4 figure

EDUCATION FOR WORK RELATED TO LIFESTYLE HEALTH

Studies performed in various countries, including Romania, have shown that a number of factors are negatively impacting the health of the population at the workplace and in the household. The connection between health and work has been researched for a number of years as an important driver towards wellbeing. Several studies have been conducted in order to identify problems and to find solutions to harmonize the balance between wealth and health. Increased globalization, the chase for competitive advantage and the reduction of costs (especially labor costs) moved employee attention of from the wellbeing of employees to higher profits. We discuss about such situations mainly in the East European Countries since the labor force is cheaper than in Western Europe. We should not forget that this current trend started in the US and was adopted also by European companies in order to increase profits. In West Europe there are quite a number of studies regarding relation between work and health, while in East Europe the number of such studies is quite small. The present paper proposes as an objective the study of several working factors and the relationship to health in Romania. Some of the results in our study reveal the concordance between the propensity of individuals to sacrifice from their one time and time for work without significant discrepancies between genders. Also the more people invest in their time to rest, the more they are able to work hard without injuries. When it comes to gender characteristics we determined slight changes in behavior with almost the same labor pattern for both participants.Another interesting finding was that rural and urban areas are clearly determining the type of stress exposure for participants with a higher impact for workers coming from the urban area. Physical exercise and labor can be channeled in good order according to the gender capabilities

Utilizarea panelurilor de consumatori in cercetarea de marketing

In legatura cu aplicarea unor metode indirecte de cercetare stiintifica a pietei, in general, precum si referitor la utilizarea unor metode directe, in literatura de specialitate se gasesc numeroase detalii, astfel incat, neconstituind scopul nostru, nu vom starui asupra prezentarii lor. Cu toate acestea, intrucat folosirea unor metode directe de investigare este, de regula, relativ laborioasa si caracteristica unor organisme specializate, consideram utile cateva consideratii teoretice si practice privind modalitatea calitativ superioara de investigare a comportamentului consumatorului prin intermediul sondajului statistic. Este vorba de conceperea, organizarea si exploatarea cercetarilor de tip panel, a caror aplicabilitate constituie in prezent o conditie sine-qua-non a lucrarilor de investigare riguros stiintifica a comportamentului consumatorului, indeosebi prin posibilitatile pe care le ofera pe plan predictiv – latura agreata cu predilectie de factorii de decizie.cercetari de marketing, analiza cantitativa, panel de consumatori, managementul cercetarii

The Effects of Increased Demand for Biofuels Feedstocks on the World Agricultural Markets and Areas - Outcomes of a Workshop 10-11 February 2010, Ispra (Italy)

This study is performed under request of DG CLIMA, in support to the preparation of the policy proposal on the assessment of the effects of Indirect Land Use Change (ILUC). Agro-economic models are used to provide estimates of how much cropland area increases in response to an increase in crop demand, but they often differ in their structure (i.e. partial or full equilibrium, agro-economic, bioenergy and biophysical models etc), in the input parameters, baseline and scenarios studied. The European Commission (EC) is debating internally how to address ILUC emissions in biofuels legislation. Legislators need to understand how ILUC differs between biofuels from different feedstocks and regions. In fact, if ILUC emissions are to be added to direct emissions in legislation, they need to be quantitatively assessed for all biofuels/feedstocks. Anyway, to compare model results it is necessary at least to compare the results vs. baseline per unit quantity of biofuel. For these reasons the JRC proposed to carry out a survey of marginal calculations from various models/methods developed by the relevant consortia in EU and US, to compare results from marginal shocks along the lines of recommended common scenarios discussed with the involved experts: A marginal extra ethanol demand in EU B marginal extra biodiesel demand in EU C marginal extra ethanol demand in US D marginal extra palm oil demand in EU (for biodiesel or pure plant oil use) For modelling the GHG efficiency of different feedstock, the experts agreed that the extra biofuels scenarios should optimally be marginal increases in demand for different biofuels-feedstock in different regions. These results would be relatively easy to compare between scenarios. Results of this survey were discussed during a workshop organized by the JRC in Ispra on 10th and 11th of February 2010, and this report presents the outcomes of the workshop, highlighting the main results of the studies and key points raised in the concluding discussion.JRC.DDG.F.8-Renewable Energy (Ispra

Prevalence and persistence of Listeria monocytogenes in premises and products of small food business operators in Northern Ireland

peer-reviewedListeriosis is a foodborne disease, with a high mortality rate, that predominantly affects the elderly. Under European Union legislation, EC 2073/2005, food business operators are encouraged to undertake sampling to ensure that the food processing environment, and required to ensure that food products, are free of Listeria monocytogenes. To determine the prevalence of L. monocytogenes in smaller food processing facilities in Northern Ireland, 24 companies submitted six processing environment swabs and two food samples every two months for eighteen months (July 2015 to November 2016) for L. monocytogenes examination. The prevalence of L. monocytogenes was 4.6% in food samples, and 6.3% in processing environment swabs. Over the duration of the study, 96 isolates of L. monocytogenes were obtained, one from each positive sample, except for two meat samples that had >100 cfu/g, where two isolates were obtained from each sample. No seasonality in occurrence of L. monocytogenes was seen for food isolates but significantly higher numbers of positive processing environment swabs were found in the warmer months of May, July and September (p = .007). Pulsed Field Gel Electrophoresis (PFGE) analysis revealed the presence of 27 pulsotypes; 9 pulsotypes were shared between different facilities and 9 were persistent. Based on a Combase predictive growth model, 77.5% (n = 130) of the foods tested were predicted to support the growth of L. monocytogenes. All of the isolates carried the pathogenicity genes inlA and actA and 71.4% carried qacH, which confers resistance to quaternary ammonium compounds which are frequently used in sanitizers. Whole genome sequencing of the isolates allowed multi-locus sequence typing to be undertaken. The data indicated that the sequence types identified included those with disease-causing ability, highlighting the disease-causing potential of the isolates

THE EMERGENCE OF ΒETA - LACTAMASE PRODUCING Escherichia coli AND THE PROBLEMS IN ASSESSING THEIR POTENTIAL CONTRIBUTION TO FOODBORNE ILLNESS: A REVIEW

Antimicrobial agents have been in use for therapeutic purposes for over a century, with most of the development occurring in the latter half of the twentieth century. Penicillin was the first of the naturally occurring antimicrobials to be used in medicine and its structure includes a beta-lactam ring. Further compounds, such as the cephalosporins, were discovered and these also included beta-lactam structures. Subsequently bacteria which were resistant to these compounds were found, and their resistance was due to their production of enzymes, beta-lactamases, which hydrolysed the beta-lactam ring. Synthetic derivatives of the beta-lactam antimicrobials were developed to render them recalcitrant to beta-lactamases but enzymes with a broader substrate range evolved, and were categorised as extended substrate beta-lactamases (ESBL). Since the antimicrobials had a significant role to play in human medicine the emergence of ESBL caused significant concerns. Further, similar antimicrobials were used by veterinarians, raising the prospect that bacteria in the commensal flora of livestock could acquire ESBL resistance properties and exchange them via genetic exchange. Thus, pathogenic bacteria present in livestock could become resistant to antimicrobials with adverse consequences should zoonotic infections occur. In this review we consider the emergence of ESBL, the problems involved in detecting and reporting such properties, and consider the consequences for consumers of potentially contaminated food product

Lower Spectral Branches of a Particle Coupled to a Bose Field

The structure of the lower part (i.e. $\epsilon$-away below the two-boson threshold) spectrum of Fr\"ohlich's polaron Hamiltonian in the weak coupling regime is obtained in spatial dimension $d\geq 3$. It contains a single polaron branch defined for total momentum $p\in G^{(0)}$, where $G^{(0)}\subset {\mathbb R}^d$ is a bounded domain, and, for any $p\in {\mathbb R}^d$, a manifold of polaron + one-boson states with boson momentum $q$ in a bounded domain depending on $p$. The polaron becomes unstable and dissolves into the one boson manifold at the boundary of $G^{(0)}$. The dispersion laws and generalized eigenfunctions are calculated

MATERIALS FOR AUTOMOTIVE INDUSTRY AND THEIR INFLUENCE ON THE DYNAMICS OF A CAR CRASH

The aim of this research was to determine the influence of the metallic materials characteristics on the dynamics of a car crash. Another important aspect is that the metallic parts are sometimes repaired after minor accidents and this fact influence strongly the mechanical characteristics and their influence on the dynamics of a car crash. In this paper, we analyze the mechanical characteristics of thin steel plates repaired by local heating associated with plastic deformation (similar to hot working) and cold straightening (similar to local cold working) for automotive side and door panels made of structural steel. Thin sheet plates, 0.9mm thickness, were deformed by impact and repaired by local heating using the flame and induction heating then plastically deformed while hot as well as straightened without heating. The heat repaired samples were studied by light microscopy to determine microstructure change and samples were tensile tested to determine their mechanical characteristics. Local excessive grain growth generates anisotropy, the assembly behaves as a composite material with regions that show significant plastic deformations while others little or no deformations at all. Without procedures adjusted to each material repairs involving heating are to be avoided, cold working should be employed when replacement is not possible
