The Impact of a Corporate Name Change on Stock Price and Trading Volume of Canadian Companies

This thesis examines the impact of a corporate name change on stock price and trading volume of Canadian companies around the announcement date, the approval date, and the adoption date over the time period from 1997 to 2011. Name changes are classified into six categories: major and minor, structural and pure, diversified and focused, accompanied with a change in ticker symbol and without a change in ticker symbol, “Gold” name addition and deletion, and different reasons for name changes (e.g., merger and acquisition, change of structure, change of strategy, and better image). The thesis uses the standard event study methodology to perform abnormal return and trading volume analyses. In addition, regression analysis is employed to examine which type of a name change has the largest impact on cumulative abnormal returns. Sample stocks exhibit a significant positive abnormal return one-day prior to the approval day and one day after the adoption date. Around the approval date we observe significant abnormal returns for stocks with a structural name change. On the day after the adoption date we document abnormal returns for stocks with major, minor, structural, pure, focused, and ticker symbol name changes. If a merger or acquisition is the reason for a name change, companies tend to experience a significant positive abnormal return one-day before the approval date and on the adoption date. If a change of structure is the reason for a name change, companies exhibit a significant positive abnormal return on the approval date and a significant negative abnormal return on the adoption date. In case of a change of strategy as the reason for a name change, companies show a significant negative abnormal return around the approval date and a significant positive abnormal return around the adoption date

Training impact on household economy from backyard chicken

One hundred out of 200 randomly interviewed females in 10 villages of Mardan were selected to establish female groups. The members were trained in backyard chicken production by Female Livestock Extension Workers under the Livestock Extension Women Worker project, North West Frontier Province (NWFP), Pakistan. Regular follow up visits were made and data prior to and after one-year of training were collected to assess the impact of training on contribution of backyard chicken production to household economy and other associated problems. Training significantly (

Accuracy of Uterine Artery Doppler in Second Trimester in Determining Pre-Eclampsia

Background: To determine the accuracy of uterine artery doppler in the second trimester (18-24 weeks) in determining preeclampsia.Methods: In this descriptive study, a total of 89 women with singleton pregnancy attending routine second-trimester anomaly scan were included. Uterine artery doppler sonography was conducted in the women coming for routine anomaly scan. Flow velocity waveforms of right and left uterine artery were imaged with the patient in the semi-recumbent position and the uterine artery was identified in the longitudinal scan, lateral to the uterus. Resistive index, pulsatility index and presence and absence of early diastolic notch and its depth in terms of notch index were calculated.Results: Uterine artery doppler finding in second trimester in determining preeclampsia showed abnormal findings in 41.57% women in which 24.32% had type I (Resistive index >0.58), 45.95% (17/37) type II (Mild notching of uterine artery at beginning of diastole) and 29.73% had type III [(Severe notching + abnormal Resistive index (>0.58)]. After the follow-up of each patient, we found that pre-eclampsia was developed in 28.09% (25/89) cases. The accuracy, sensitivity, specificity, positive and negative predictive values of uterine artery doppler were 75.28%, 80%, 73.44%, 54.05% and 90.38% respectivelyConclusion: By detecting abnormal uterine artery Doppler indices (high RI) between 18-24 weeks of pregnancy can identify those women who are at risk for development of preeclampsia

A STUDY OF INTERNET THREATS, AVOIDANCE AND BIOMETRIC SECURITY TECHNIQUES - COMPARISON OF BIOMETRIC TECHNIQUES

In today’s IT world, most of the communication is done through networking. So, security of information is very crucial. A lot of techniques have been developed for security which involves passwords, encryption, digital signatures etc. But there are chances of vulnerabilities in these techniques and hackers can break the security algorithms of these techniques. So, in this era, researchers have moved towards biometric techniques of security. It involves identification of people based on their physical characteristics or psychological behaviors. A choice of biometric method to be used is made depending on the level of security required and the goals of the system. Biometric identification is very excellent and secure way of authenticating people. But it can also suffer from security threats, if proper design considerations are not taken into account. This work presents details of biometric techniques and a detailed comparison of most famous biometric techniques

Advanced Carbon Functional Materials for Superior Energy Storage

In the developing world, energy crisis is the main reason for less progress and development. Renewable and sustainable energy may be of bright future for scientific lagging and low-income countries; further, sustainability through smart materials got a huge potential; so, hereby keeping in view the energy crisis which the developing world is facing for many decades, we are proposing to write a chapter project for obtaining energy through cheap, sustainable, and functional advanced carbon materials. Carbon materials are the future of energy storage devices because of their ability to store energy in great capacity. The graphene is a material with amazing properties like no band gap, which turns graphene a wonderful candidate for use in the photovoltaic. Shortly, this chapter will discuss how superior energy storage may be obtained through various routes like using pyrrolic (N5) and pyridinic (N6) doping in advanced carbon functional materials, or superior energy by KOH activation in carbon materials, or through carbonization in organic matter, respectively. Further, for the advanced carbon functional materials, the superior energy storage using pyrrolic (N5) and pyridinic (N6) doping, or KOH activation, or through carbonization will be discussed one by one for lithium ion batteries, supercapacitors, and relevant energy devices, respectively

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
