Principles of Management

Definition of Leadership
Leadership is the process by which individuals can guide, direct and influence other’s behaviors towards the accomplishment of set goals. It is the ability to influence others towards the realization of a goal. A leader plays various roles to induce follower to take their roles with confidence and zeal including developing future visions and motivating to attain the visions. Leadership denotes the number of qualities to be present in an individual. Leadership is situation bound, and there is no best style of leadership (Nahavandi, 2016). There is a difference between the concept of leadership and the concept of management. Managers are fundamentally focused on directing people and allocating resources to accomplish tasks (Grohar et al., 2016). Managers employ strong administrative abilities, given that much of their role involves providing instructions to subordinates and reporting results to superiors. Leaders can be managers.

Personal Skills/Weaknesses

Strengths
As a leader, my greatest strength lies in being Open-minded. I keep my mind open while being flexible. This enables me to adjust when necessary. I am also committed to investing, developing and maintaining great relationships. I consider myself a decisive person. The rapid pace of processes and increasing time pressures necessitates dealing with the speed amidst the complexity. I tend to make sound, justifiable decisions in a timely manner, particularly in times of uncertainty and crisis. I am also inspirational. People say I am self-driven and fueled by my beliefs as well as an internal drive and passion. I am a persistent individual. I believe that persistence beats resistance. Some things take the time to accomplish. To achieve them, there is a need for persistent. As a result, I am always willing to go beyond where others stop. I am also a good communicator. I easily make people aware of my expectations, thoughts, and ideas.

Weakness
I have various weaknesses. The first weakness lies in my tendency to be a perfect. I get things done right. However, this leads to attrition and burnout. As a result, it may diminish potential returns over time. I realize the importance of being more accommodating and accepting of small failures, letting go and delegating, allowing for diversity of action and thought and understanding that good enough is often good enough. The second weakness is that I am Over-optimism about strategies and people. The tendency has negative impacts as I may hang on to lower-performing individuals and strategies for too long. As a leader, there is need to recognize the grace in realism so as to see things accurately as they are versus how they should be.

Description of Leadership Experience
One of the most memorable leadership experiences was a picnic trip in summer 2016. The event took place on the month of August. Throughout the trip to Andover City Park in Kansas, I played the role of a leader. My role was to lead my group of 15 members. As the recreation trip leader, I was responsible for planning, leading, instruction and facilitating activities. Safety, as it pertains to the picnic, the skill level of students, and location that the trip was of main concern. I comfortably managed a diverse group of people during the outdoor setting and made decisions for the good of the group. In addition to leading the group, I assisted patrons with their outdoor adventure equipment needs including training, fitting and educating students about the outdoor adventure kits. I was expected to correctly operate cash and reconciliation procedures and engage students in a supportive and friendly demeanor. As the leader, I felt proud that students recognized my leadership skills.

Leadership Skills Used
Communication

The activity required the leader to use a number of skills. Communication skill was the most commonly used throughout the activity. As a leader, it is necessary to be able to clearly and succinctly express expectations to your followers. As a leader, it is important to master all forms of communication through all available means. A large part of communication involved listening. The first step was to establish a steady flow of information between team members through regular conversations with team members.

Motivation
As a leader, I inspired my team members to go the extra mile for the purpose of achieving our objectives. I motivated my teammates through different ways. These include building their self-esteem and giving them responsibilities to increase their participation in the activity.

Strategic thinking
This was perhaps the most critical skill I utilized. Application of this skills involved having an objective of what was expected and influencing team members to achieve that objective. It could not be possible to achieve objectives without communication, optimism, crisis management and effective solving of conflicts between team members. It is clear that working in a team may prove difficult than working as an individual. This is particularly so when team members have conflicting goals, fail to share information and lose themselves in an unproductive argument. Critical thinking helped create a sense of urgency also contributed to the effectiveness of the team. I was able to propel team members to get busy and carryout the activity at the desired pace.

Summary
Leaders focus on influencing others. Unlike managers, followers follow leaders due to their personality and their beliefs. As a leader, my greatest strength lies in being Open-minded, persistent, commitment to investing, developing and maintaining great relationships. I have various weaknesses including perfectionism and Over-optimism. My leadership experience was a picnic trip in summer 2016. As the recreation trip leader, I was responsible for planning, leading, instruction and facilitating activities. Skills used include Communication, Motivation and critical thinking.

Oracle vs sql server

Introduction
Any enterprise evaluating a database management system solution for their data should also evaluate the systems regarding their management of data. The capabilities of the servers to properly manage data is the essence of having them in organizations since data is one of the most critical assets in any business whereby the success of any organization depends on how well it can use its data to make business decisions. The data needs to be available and its integrity and confidentiality preserved. If the data of organizations is not available or not protected, the enterprises are likely to lose millions of dollars due to unplanned downtime and negative publicity. Having good data management in organizations is critical to ensuring business success in today’s economy. The document offers a detailed comparative assessment of the two most popular servers, that is, Oracle and SQL Servers in light of data management.

Overview of Data Management in Oracle vs. SQL Server

One of the greatest challenges in the design of high availability information technology (IT) infrastructure is addressing the issues of data management. Data management, when it is done properly can reduce downtime that many organizations always face (Bassil, 2012). The IT companies should consider the potential causes of both planned and unplanned downtime when they are designing their IT infrastructure. We know that a server does play a dispensable role in managing the data so that it is always available and in the form I which it was saved. That helps in the continuity of business operations because they highly depend on that data. Data failures in organizations can result from the human errors, data corruptions or disasters, a, so it is the responsibility of a database management system to make sure that it includes features that can highly manage the data so that it is not negatively impacted by those events (Oracle Corporation, 2013).

While data failures are not frequent, their adverse effects on the business operations are very significant because it results in high costs of downtime. The database management system used, whether Oracle or SQL Server should allow for the maintenance activities to take place transparently, and that causes no or minimal interruptions to the normal business orations. The Oracle database comes with a plethora of capabilities integrated to ensure that organizations can minimize data failures as much as possible so that they do not adversely impact their businesses (Callan et al., 2010). For instance, the Oracle Multitenant is a new option in Oracle that delivers a groundbreaking technology useful in database consolidation as well as cloud computing. It also makes extreme high data and system availability a fundamental requirement wherever database consideration ahs application to the business critical applications.

The Microsoft Corporation introduced the Always On solution in their SQL Server for the purpose of addressing the issue of high availability and disaster recovery requirements. The major features that are inclusive in SQL Server include the always on failover to address the instance failovers and the AlwaysOn Availability Group to address the failover of a set of databases (Bassil, 2012). Although the SQL Server introduced these new capabilities to better manage data, it cannot match the breadth and depth of the data management capabilities found in Oracle (Oracle Corporation, 2013). The SQL Server continues to lag behind regarding data availability and for that reason, the Oracle database has application in many companies that require high data management and system availability. There are also many differentiators as explained below regarding how data management takes place in Oracle and SQL Server. Note that the SQL Server referred to here is the SQL Server 2012 whereas the Oracle database referred is the Oracle 12c EE (Enterprise Edition).

The Oracle database incorporates an inbuilt database failure detection, repair, and analysis whereas the SQL Server lacks this feature (Oracle Corporation, 2013). In the light of this matter, Oracle includes a fast-start fault recovery functionality that controls the instant recovery. The feature helps in the reduction of the required time for cache recovery as well as recovery bounded by limiting the dirty buffers and redo records that are regenerated between the most recent record and the last checkpoint. The fast-start checkpointing in Oracle eliminates the bulk writes as well as the resultant I/O spikes that do occur in the case of conventional checkpointing (Callan et al., 2010). Unlike in SQL where the database is not open for applications to access only after the undo or rollback phases, the Oracle database is accessible by applications without the need to wait for the completion of rollback of undoing phases (Kumar, 2007). In the latter, in case, the user process encounters a crashed transaction that locks a row, what the database does is that it rolls back that row.

Whereas the SQL Server stores the undo data in the log files, the Oracle database stores similar data in the database, making the recovery process is very fast in Oracle than in SQL (Callan et al., 2010). The SQL Server has to carry out expensive sequential scanning of the log files, hence increasing the mean time to recover from a data failure. Also, in Oracle, there is an incremental backup strategy while SQL server supports partials backup strategy. Oracle also incorporates a proactive disk health checks using an automatic corruption repair while the SQL Server does not have such a feature (Oracle Corporation, 2013). The data manager in Oracle does not have to check manually for the health of the disks because of that automatic feature. That simplifies the work of managing the data in Oracle as compared to the same tasks in SQL Server where there have to be manual disk health checks.

The standby apply progress in the Oracle databases does not have any performance impact on the primary database or data protection whereas in SQL Server it does have an impact (Callan et al., 2010). However, in Oracle, there are silent corruptions that can be detected as a result of software/hardware faults at the standby and the primary database; such defaults are not detectable in SQL Server. Oracle can quickly recover from logical corruptions and the human errors while in Oracle, it takes a long time to recover (Bassil, 2012). That is because SQL Server puts much responsibility on the hands of the database manager whereas the Oracle database comprises of features that make the recovery automatically. The Oracle database includes the integrated and automatic database failover that guarantees a zero data loss as well as a no split-brain (Kumar, 2007). That feature is lacking in SQL server, thus making it vulnerable to data loss.

The SQL Server’s AlwaysOn feature is a failover cluster instance running in a failover cluster that comprises of multiple failover clustering nodes for Windows. That offers a high availability via redundancy especially at the instance level (Kumar, 2007). That can also be useful in providing remote disaster recovery using multi-subnet failover cluster instance. It allows the hosting of an availability replica by either a failover clustering instance or a standalone instance of the server. That means the database manager can use the failover clustering instance for local instance-level high availability as well as the Availability Groups to offer database level disaster recovery. That feature may give an impression that it is similar to Oracle’s data guard and real application clusters. While the SQL Server’s failover clustering instances and the secondary nodes are all passive: are offline and do not start the SQL Server instances in a steady-state, the Oracle data guard and the real application clusters do start their respective database instances in a steady-state mode and are always online (Kumar, 2007). That is useful in data management at all times.

Discussion question

Introduction
In various scientific inquiries, our aim is always to establish the causes of something. For example, we might want to establish the true causes of autism or causes of cancer or how the drug enables a patient to feel better and less pain. Also, we can be interested in knowing which cultural practices result in environmental problems in many other aspects. In such instances, we are testing the causal models. On the other hand, scientific studies also aim to establish the correlations between variables. Correlations aim at finding out the associations of variables. Variables are aspects that researchers measure which may differ from one observation to another, for example, behavior, weight, height, lifespan, income, grade-point average and fat intake. With the variables, we can assign a value to represent the variables.

Causation and correlation

We frequently experience instances of misuse between causation and correlation. For example in a British newspaper, it provides reports from a group of teenagers who were to give information about their behaviors. The survey aimed to establish if the parents of these teenagers were smokers. As a fact, the newspaper reported that children were exhibiting delinquent behaviors had parents who smoke. The results of this study seem to indicate correlations between two variables. However the headline of this printed newspaper is entitled, “”Parental smoking causes children to misbehave” Criticalthinking.org.uk, 2006). The professor in charge of the investigation mentions that cigarettes pack should have a warning b about the prominent health warnings and various social issues. However, this is a problematic assumption. First, the correlations there might be a reverse in that delinquent children make their parents have stress making them smoke.

Another example of a correlation that is assumed to be a cause is that children with bigger feet can better spell than those with smaller feet. The odd results of this study’s explanation are that those children with bigger feet are older and not quite related to being better in spelling. As children grow they develop big feet (Paulo, 2010).

Another example is that the countries in the south have high rates of divorces and lower rates of death. There is also the example that nations adding fluoride to their water experience a high level of cancer unlike those which do not. Though there are studies that have come to such findings, these responses would make more sense if the researchers would acknowledge the differences between causation and correlations (Murch, et al., 2004).

The 1998 study kindles the opposition to vaccine firestorm that provides suggestions that autism is as a result of vaccines have no support from the General Medical Council. The participants were biased, and it made the researcher commit various ethical breaches in his work. Andrew Wakefield‘s research paper no longer exists. The Researcher analyzed the health of 12 children showing signs of colon inflammation and autism shortly after receiving the MMR vaccinations (Wakefield, et al., 1998). T

hough this study raises alarms about autism and vaccine, a closer examination of this paper indicate a range of warning signs.. The researchers in their conclusion state flatly that, we did not find a close association between mumps, measles, and the syndrome and rubella vaccine. The researcher mentions that they have managed to identify that chronic enterocolitis among children could relate to neuropsychiatric dysfunction. Additionally, they state that the onset of symptoms was after, rubella, mumps and measles immunization. And that further examination should be done in studying the symptoms and its possible relation to the vaccine). This is a tame language and only studying 12 participants makes the study to lack credibility and validity (Stehr-Green, Tull, & Simpson, 2003). Up to date, no study has established the connection between autism and MMR shots. The evidence of a-pick-and-choose recruitment method is bias leading to a discredit of its conclusion (DeStefano, 2007).

Correlation provides a statistical measure that describes the direction and size of the relationship between one or two variables. However, the correlation between variables does not automatically mean a change in one of the variables as being the reason for the change in other variables values. Causation, however, means that one event leads to the occurrence of another event which means that there is a causal relationship in two variables (The Lancet, 2010). For example, smoking has a correlation to alcoholism, but it is not the main cause of alcoholism. Rather smoking causes a higher risk of lung cancer development.

Therefore incorrectly linking causation and correlation principles will lead to posthoc reasoning in which the incorrect assumptions generations are the incorrect links of two effects. The principles of causation and correlations are crucial to all researchers and scientists. It is also important for other not -scientists who study marketing, media and politics. Knowing these principles helps to promote honest evaluation and greater understanding to individuals at all ages (Science Daily, 2013).
