Social Media And Its Effect On Communication - 1361 Words

During a crisis, social media channels such as blogs, Facebook pages and instant messages can be used to keep stakeholders updated, stay connected with stakeholders, and collectively find a solution to overcome a crisis (Ulmer et al., 2015). While a number of social media characteristics are typically considered before its adoption in communication activities, three characteristics are mentioned more frequently in communication literature. In most crisis communication studies, speed, ease of reach and a personalized conversation are recognized advantages of social media. These particular advantages were supported by Schultz and colleagues (2012) in their review of the existing literature on this topic. Compared to traditional media, which†¦show more content†¦Moreover, Ruehl and Ingenhoff (2015) asserted that by sharing information on organization-owned social media channels, an organization can see immediate results of their efforts, enjoy increases in the number of followe rs or â€Å"likes,† in the number of conversations (posts on Facebook wall), and in amplification (â€Å"shares† of a post among networks). Ruehl and Ingenhoff (2015) believe that communicating corporate values on social media can increase stakeholder engagement with an organization. As a result, many scholars agree that the interactivity and swiftness of social media have made it a preferred choice for organizations to communicate with stakeholders (Capriotti Kuklinski, 2012). Additionally, as a collection of online channels, social media has five distinct features, detailed by Coombs (2014): †¢ Participation: Any social media user can create, distribute and give feedback on content. †¢ Openness: Social media owners allow others to post and give feedback on content on their channels. †¢ Conversation: The channels facilitate dialogue. †¢ Communities: People with the same interest can form groups easily and quickly. †¢ Connectedness: One content item is heavily linked to another, thus creating a â€Å"web† of information. Combined, these five features allow social media users to reach one another easily and conveniently. In times of crisis, this ease of reach can be both an advantage and disadvantage to organizations. On one hand, it provides organizations an opportunityShow MoreRelatedSocial Media And Its Effect On Communication1269 Words   |  6 PagesSocial media and social networking seems to be play an imperative part in individuals lives around the world.

Payroll In a company, payroll is the sum of all financial records of salaries for an employee, wages, bonuses and deductions. In accounting, payroll refers to the amount paid to employees for services they provided during a certain period of time. Payroll plays a major role in a company for several reasons. We will write a custom essay sample on Payroll or any similar topic only for you Order Now From an accounting perspective, payroll is crucial because payroll and payroll taxes considerably affect the net income of most companies and they are subject to laws and regulations. Definition of ‘Payroll’ The sum total of all compensation that a business must pay to its employees for a set period of time or on a given date. Payroll is usually managed by the accounting department of a business. Small-business payrolls may be handled directly by the owner or an associate. Investopedia explains ‘Payroll’ Payroll can also refer to the list of employees of a business and the amount of compensation that is due to each of them. Payroll Is a major expense for most businesses and Is almost always deductible as such. Payroll can differ from one pay period to another due to overtime, sick pay and other variables. The primary mission of the payroll department Is to ensure that all employees are paid accurately and timely with the correct withholdings and deductions, and to ensure the withholdings and deductions are remitted In a timely manner. This includes salary payments, tax withholdings, and deductions from a paycheck. Companies typically generate their payrolls at regular Intervals, for the enefit of regular Income to their employees. The regularity of the Intervals varies from company to company, and sometimes between Job grades within a given company. Common payroll frequencies Include: dally, weekly, bl-weekly/fortnlghtly (once every two weeks), semi-monthly (twice per month), and to a somewhat lesser extent, monthly. Less common payroll frequencies Include: 4-weekly (13 times per year), bl-monthly (once every two months), quarterly (once every 13 weeks), semi- annually (twice per year), and annually.

Analysis And Proposal confidence prediction - Myassignmenthelp.Com

Question: Discuss about the Analysis And Proposal confidence prediction. Answer: Article analysis The title of the article is A Burkholderia Type VI Effector Deamidates Rho GTPases to Activate the Pyrin Inflammasome and Trigger Inflammation Summary Burkholderia cenocepacia is a Gram-negative environmental pathogen that causes opportunistic infections in the lungs of patients with cystic fibrosis (Juhas et al., 2012). The type VI secretion system of B. cenocepacia is required for its pathogenesis (Rosales-Reyes et al., 2012). This secretion system inactivates the Rho type GTPases, thereby causing downregulation of the phagocytic activity of macrophages, blocks assesmbly of the NADPH oxidase onto the vacuole containing the B. cenocepacia and also causes disruption of the actin cytoskeleton of macrophages (Rosales?Reyes et al., 2012; Toesca, French Miller, 2014). It also causes activation of the secretion of interlekins (IL)-1/18, macrophage pyroptosis and caspase 1 inflammasome (Gavrilin et al., 2012). This study identifies a non VgrG type VI secretion system effector molecule responsible for disruption of the actin cytoskeleton of macrophages. This Type VI secretion system effector is termed as TecA. This TecA effector causes d eamidation of of the Rho-GTPases. The target amino acid of TecA is asparagine. Deamidation of the asparagines 41 causes inactivation of the GTPases and eventual disruption of the actin cytoskeleton of host macrophages. Deamidation of RhoA by TecA causes activation of the Pyrin inflammasome, which in turn causes inflammation in the lungs. Thus, this study characterizes TecA and identifies its role as a non-VgrG type VI secretion system effector and carries out modification of the eukaryotic host, thereby causing host cell death and inflammation. Knowledge gap addressed and the main thesis of the article Very few reports are available regarding the characterization of Type VI secretion system effectors belonging to the non-VgrG family (Jiang et al., 2014; Miyata et al., 2013). Moreover, the physiological functions of the few non-VgrG family Type VI secretion system effectors reported were not identified (Valvano et al., 2015). Moreover, no reports were previously present that dealt with Type VI secretion system effectors of B. cenocepacia that can carry out disruption of the actin cytoskeletons of macrophages, thereby altering their physiology. The main thesis of the paper is to identify and characterize the mechanism of action of the Type VI secretion system effector TecA in B. cenocepacia pathogenesis. Hypothesis and Experimental methods The hypothesis for the first figure is the identification of the tecA gene encoding a non-VgrG family Type VI secretion system effector that can carry out alterations in host targets. The first hypothesis deals with the genetic mapping of tecA, which was found to be located in the chromosome 2 of B. cenocepacia K56-2 strain. B. cenocepacia tecA mutants when infected into macrophages produced a bead like appearance phenotype, which got abolished when tecA was expressed in trans through a plasmid. Thus, it was found that mutation of TecA affected its ability to carry out actin rearrangements. The hypothesis for the second figure identifies the target of TecA. It was found that TecA causes RhoA deamidation at the asparagines residue located at position 41. Mass spectrometry helped to identify the amino acid that is modified in RhoA. The hypothesis for figure 3 is that TecA is highly essential for deamidation of Rho and when mutated cannot carry out deamidation. Complementation of the te cA mutant with TecA expressed from a plasmid helped to induce RhoA modifiucation and mass spectrometry helped to show that asparagines at position 41 of RhoA gets converted to aspartic acid by TecA. Moreover, Rac1 was found to be modified at position 39, which is homologous to RhoA that undergoes modification at position 41. The hypothesis of the fourth figure is that TecA is a deamidases that modifies Rho type GTPases. BLAST analysis was carried out to determine the other TecA orthologs. Homologs were also identified. A conserved Cys-His-Asp sequence were identified, where the cysteine acts a s a nucleophile. Moreover, in silico modeling were also carried out. The hypothesis for the fifth figure is that RhoA deamidation activates the Pyrin inflammasomes. Mutation of tecA was unable to cause caspase 1 activation, interleukin secretion and pyroptosis. However, mutation of the residues of the catalytic triad resulted in loss of function of TecA. The hypothesis for the last figure is t hat TecA causes lung inflammation and when recognized by Pyrin, it gives protection from severe lung infection in mice. Immunoblotting and ELISA experiments were carried out. The results were highly compelling as these helped to identify the mechanism of action of TecA and also the targets that are modified by TecA in eukaryotic hosts. Conclusion The article is highly compelling as it for the first time helps to demonstrate the effects of a non-VgrG family type VI secretion system effector TecA in the pathogenesis of B. cenocepacia. This study carries out the experiments in mice models, but future experiments are needed to determine the effect of TecA in plant and insect models. Moreover, it is also necessary to determine whether TecA from B. cenocepacia can function in other pathogens using the Type VI secretion system. It is necessary to determine the position of TecA where the substrate RhoA binds. Research Proposal The title of my research proposal is Identification of the binding site of RhoA in the deamidase TecA in B. cenocepacia. The substrate binding site of TecA is not known, so my research objective would be to determine the binding site for RhoA in TecA. Hypothesis Hypothesis 1 The deamidase TecA has a specific binding site for its substrate RhoA. RhoA binding domains have previously been identified in other species, hence it is necessary to determine the binding site of RhoA in the deamidase TecA (Shang et al., 2012). This can be carried out by application of yeast 2 hybrid screens (Stynen et al., 2012). It will help to determine the binding site of RhoA in TecA. Hypothesis 2 The binding sequence for RhoA in TecA of B. cenocepacia shows significant homology with the other identified RhoA binding proteins. Sequence homology needs to be determined by carrying out sequence analysis using bioinformatic tools like BLAST, CLUSTALW, among others. This will help to determine the binding site sequence of TecA. Hypothesis 3 TecA carries out deamidation of RhoA in plant and insect models. To address this hypothesis, mutation of TecA will be carried out, followed by introduction of the B. cenocepacia tecA mutants in plant and insect cell lines. The ability of the mutants can be determined by its ability to carry out actin disruption in the host macrophages. For this phase contrast microscopy can be carried out. This will help to determine whether TecA has the same mechanism of action in other eukaryotic host models. Hypothesis 4 Overexpression of TecA from B. cenocepacia can complement the phenotypes of the tecA mutants in other pathogenic microorganisms. To address this hypothesis, tecA mutant of other pathogenic microorganisms can be complemented with B. cenocepacia TecA. TecA from B. cenocepacia can be cloned in an expression plasmid and overexpressed in trans in the tecA mutants in other species. Phase contrast microscopy can be carried out to determine the effects of overexpression of B. cenocepacia TecA on the stability of macrophages. This experiment will help to determine whether TecA can function in heterologous hosts as well. Bibliography Gavrilin, M. A., Abdelaziz, D. H., Mostafa, M., Abdulrahman, B.
