Drivers for Internationalisation

Case Study Arc Solutions Provides a Centrally Controlled Operator Center Solution to Heffernan Group

...Case Study Arc Solutions Provides a centrally controlled operator center solution to Heffernan Group s o l u t i o n s The Challenges With an overall emphasis on customer service excellence, communication both internally and with customers has always been a key element to the success of the company. Whilst effective, this solution was not ideal as the company’s main aim was to ensure that all customers were dealt with personally by the operators. Having separate telephone systems serving each site also provided challenges, with the infrastructure being inflexible and a high systems management overhead. It also meant that operators had to be deployed to cope with the incoming traffic of that particular branch office, with no capability to share the load with other offices in busier times. Heffernan therefore decided to move to a single centralized communications platform, serving all sites. They chose Cisco Unified Communications technology as it delivered the power, flexibility and reliability to serve the whole business and its customers, both now and in the future. Whilst this provided an excellent platform for unifying communications across the enterprise, Profile Heffernan Insurance Brokers, formed in 1988, is one of the largest independent insurance brokerage firms in the United States. Heffernan provides comprehensive insurance and financial services products to a wide range of businesses and individuals. Headquartered in Walnut Creek, California, Heffernan has...

Ptsd Literature Review

...The need for a clinical treatment of Post Traumatic Stress Disorder (PTSD) sits at the forefront of research in the psychiatric community. With its emergence as a defined disorder, rather than a label of “extreme trauma” or “shellshock,” PTSD exists as one of the more difficult psychiatric disorders to treat successfully. Although several treatments are available at the clinical level, the success rate for curing the PTSD patient remains small and pervasive. In recent years, mental health providers, through numerous studies and related experiments, concluded that PTSD patients respond most favorably to a multi-layered treatment process. With the use of Cognitive Behavioral Therapy (CBT), drug therapy, group-based therapy and other forms of psychotherapy, patients are achieving a higher cure rate and lower rate of re-occurrence. PTSD is an anxiety disorder triggered as a result of an extreme traumatic event in a person’s life. This trauma might be the result of battle, death, abuse, or violence of any sort. The trauma can cause symptoms to manifest within a month of the event or lay dormant for a period of time, according to all definitions of PTSD. This disorder causes the traumatized to continually re-live the event, to separate from anything associated with the event, either perceived or real, and to become numbed to their normal life process. Another specific reaction to PTSD is hyperarousal, or a heightened sense of watchfulness or paranoia. These symptoms are usually...

...stakeholders the process for uncovering, determining the scope of, and managing program uncertainties. Since risk can be associated with all aspects of a program, it is important to recognize that risk identification is part of the job of everyone and not just the program manager or systems engineer. That includes the test manager, financial manager, contracting officer, logistician, and every other team member. The purpose of this guide is to assist DoD and contractor Program Managers (PMs), program offices and Integrated Product Teams (IPTs) in effectively managing program risks during the entire acquisition process, including sustainment. This guide contains baseline information and explanations for a well-structured risk management program. The management concepts and ideas presented here encourage the use of risk-based management practices and suggest a process to address program risks without prescribing specific methods or tools. (Note: this guide does not attempt to address the requirements of DoDI 5000.1 to prevent and manage Environment, Safety, and Occupational Health (ESOH) hazards. The reader should refer to MIL STD 882D, Standard Practice for System Safety, for guidance regarding ESOH hazards).

The study of unaccounted income thereafter was entrusted to the National Institute Of Public Finance And Policy in July 1982 to: identify sectors generating black money, causes of such, studying the methods employed to generate black money and channels through which concealed income is invested and spent in other ways, methods employed to convert black money into white, broad estimate of money generated and to take regional or sectoral surveys required in connection with the above. The Institute submitted its report in March 1985. The focus of the paper is on methods and measurements of estimating black economy and therefore, other aspects of the report like distinguishing between black income and black wealth, giving an explanation for the causes of black economy and remedial measures etc. are not explicitly dealt with, yet these issues are kept in mind and the methods and measurements are discussed at the level best. This paper has tried to do some justification to the NIPFP REPORT (1985) and the comments by various known scholars. METHODS FOR ESTIMATING BLACK INCOME The first approach is the fiscal approach: Variants of this approach attempt to arrive at independent estimates of incomes subject to tax and compare these with the income actually assessed for taxation and call the...

...Chapter 5 Organizational Development and Change Chapter Overview The organizational development (OD) tradition is a practitioner-driven intervention-oriented approach to effecting organizational change via individual change, with view to increasing effectiveness. It is implemented within a problem-solving model, places a heavy accent on survey-based problem diagnosis and subordinates people to a vision of the future. Commitment-based strategies of effecting change assume that the impetus for change must come from the bottom up, whilst compliance-based strategies involve the creation of behavioural imperatives for change. Various ‘employee involvement’ strategies are reviewed, but there is little evidence for their effectiveness either as a means of securing commitment or enhanced performance, or as a means of leverage for change. Culture is assumed to be the primary vehicle for change within the OD tradition, although the relationship between culture and the change process is ill understood. Finally, the assumptions underpinning team development, and its implementation, are critically examined. The organizational culture literature itself is fraught with epistemological debate. Practitioners are interested in management by measurement and manipulation of culture. Theoreticians of culture, however, aim to understand the depth and complexity of culture. Unresolved issues remain regarding how to define culture, the difference between culture and climate, measurement/levels...
