What different types of Facebook marketing objectives are there, and what tactics can you use to reach those.

Social media is creating attractive business opportunities for brands and companies worldwide. It is because of the huge amount of businesses and costumers on Facebook, which reflects the importance of research on future marketing. The purpose of this dissertation is first to identify different types of marketing objectives on Facebook, and secondly to identify tactics to reach the different objectives. We conducted an inductive and a deductive approach based on a grounded theory method. Grounded theory differs from other qualitative methods because of the explicit guidelines that explain researchers how to proceed. We conduct eight in-depth interviews with four different communication agencies and four different businesses already integrated in social media marketing on Facebook. We built concepts and categories based on grounded theory and built a theory for our purpose of this dissertation. To get some more verification of our grounded theory we approached a Norwegian software agency that works with building platforms for creating Facebook applications. We analysed data given to us by the agency and compared their data with ours. Our findings suggest that sales, branding, customer service and conversions, are the overlying objectives businesses can achieve on Facebook. All of these objectives have more specified objectives underlying them, and to reach these objectives on Facebook our findings suggest four important success factors. It is important for businesses to define and gather their audience on Facebook in order to achieve any of the objectives, and they need to communicate their brand and create value on their Facebook page. It is a constant battle on Facebook to entertain your audience through engaging content. In order to know what your audience thinks is engaging, our data suggest that constant research on your audience is importuning. We create a model for engaging content based on our findings, and define tactical elements to achieve the different objectives. Our findings contribute to earlier research on social media objectives and create an overview of the objectives that can be achieved on Facebook. We believe that our findings will help businesses to make better decisions in their future marketing campaigns and strategies

Time Synchronization in Distributed Systems without a Central Clock

Time synchronization and a common understanding of the concept of time is an essential and important aspect of modern computing. Among the drawbacks of current and popular methods, such as the Network Time Protocol, (NTP), or the Precision Time Protocol, (PTP), are the need for live synchronization, and the use of a central reference clock. While these methods are ideal in an environment with constant, uninterruptible, and reliable internet connection, they may prove impracticable in a number of scenarios including Internet of Things (IoT) devices. In cases where the is no access to a central clock, or where the accuracy of two clocks is paramount yet there exists no reliable network access, new methods for synchronization are needed. Our proposed method utilizes existing hardware, without the need for onerous algorithms, in order to establish time-accuracy between two devices. The method effectively establishes a master-slave relationship between two computers, and endeavors to find the difference in time between the two devices, over a period of time. This reduces the reliance on constant, and on-going connection to a central clock. Further, in cases where methods such as NTP, or PTP may be preferred, our proposed solution can bolster those protocols

The Smartphone Use and Insomnia Incidence in Health Students

The incidence of insomnia is often found in many people, especially at a young age, such as college students. The use of technology such as smartphones is suspected to be one of the causes of insomnia. This study aims to analyze the relationship between smartphone use and the incidence of insomnia in college students. This study uses a kuantitative research with a cross-sectional study design. The research was conducted on health students at various universities in Kendari City, namely FKM UHO, FK UHO, Pharmacy UHO, STIKES Mandala Waluya, ITK Avicenna and Poltekkes Kendari, class 2018-2021. The sample size of 400 respondents was taken using the proportionate stratified random sampling technique. Collecting data using an online questionnaire with google form media. Data analysis used chi-square test with 95% confidence level. Excessive smartphone use was identified in 387 (96.7%) respondents. A total of 372 (93.0%) respondents experienced insomnia. There is a relationship between smartphone use and the incidence of insomnia in health students in Kendari City (p = 0.00). Therefore, it is very necessary to limit activity and duration of smartphone us
