Exploring and Unraveling Autism Essay - 2244 Words

Autism Spectrum Disorder, known as ASD, is a range of complex neurodevelopment disorders, characterized by social impairments, communication difficulties, and restricted, repetitive, and stereotyped patterns of behavior. Autistic Disorder, referred to as autism or classical ASD, is the most common and severe form of ASD. Other less severe conditions along the spectrum include Aspergers Syndrome and Pervasive Development Disorder. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize. It is not completely understood as to why this occurs. Autism has a strong genetic basis and in rare cases, it is strongly associated with agents that cause birth defects. According to the†¦show more content†¦In 1943, an Austrian-American psychiatrist, Dr. Leo Kanner was one of the first to specialize in child psychology and was credited with recognizing autism as its own unique mental disorder. Kanner discussed his researc h based on a group of eleven children who all displayed similar conditions such as social interaction difficulties, difficulty processing and adapting to changes, particularly good memory, and exceeding sensitivity to sounds and other stimulants. Kanner used the term â€Å"autism† to describe the main characteristics that all of the children he studied displayed – little to no interest in socializing with others. Lastly, Dr. Hans Asperger, a scientist and pediatrician in the late 1900s, also contributed research and multiple studies on children with autism. Dr. Asperger is best known in the history of autism for defining Aspergers Syndrome. Aspergers Syndrome is a less severe condition disorder along the spectrum. Aspergers Syndrome is characterized by significant difficulties in social interaction, alongside restricted and repetitive patterns of behavior and interests. It differs from other autism spectrum disorders by its relative preservation of cognitive deve lopment. For many years, autism was rare, occurring in just five children per 100,000 live births. However, according to the Autism Research Institute, since the the early 1900s, the rate ofShow MoreRelatedStephen P. Robbins Timothy A.

Features Of A Relational Database - 2318 Words

Features of a relational database Primary keys: The main feature of a relation database would be the primary key. It is a unique identifier set to each and every record that travels across different tables in relationships. An example of a primary key is a Social Security number. The primary keys job is to make each record unique and it lets data to be kept in more than one table. Each table within a relational database will have a field for the primary key. Foreign keys: A foreign key is a column in a database that links data between tables by cross referencing because it references primary keys from other tables. For example if there are two tables, customer and order then a†¦show more content†¦It can also be broken down into short, medium and long date/time.

Yes : No On : Off Validation rules Validation within a database is used to make sure the data entered into the database is sensible and makes sense, also to avoid any typing errors. You make a rule which only allows certain things to be typed into the database e.g. only 11 numbers for a mobile phone number so that you don’t accidently type the wrong amount of digits. It will come up as an error if you try and then that is when you notice your mistake. Benefits Having a relational database will greatly reduce the data redundancy because it will get rid of the repeated data within a database. This is done by going through the normalisation process and therefore since there is less data in the database it is much faster access, searching data, updating data, sorting and reporting.

Transforming System Requirements into Model Checking Specifications

Question: Discuss about A systematic approach to transforming system requirements into model checking specifications? Answer: Summary The software industry has been afflicted by the volatile, ambiguous, inaccurate and incomplete requirements since its emergence. The confluence of formal methods and development based on model proposes innovators of the critical-safety systems a strong and a new access for the validation of necessities at the early stage. This particular paper explains a case study that had been conducted to adjudicate if the use of formal methods could validate the system requirements at a reasonable cost in the lifecycle. Quite a few safety and functional requirements were captured for logic of Flight Guidance System (Aceituna, Do and Srinivasan 2014). They were written in natural language or shall statements. The model was formally written in RSML language. Several errors were identified in both the RSML as well as the original language. This proved that the formal models can be used for writing realistic or sensible systems and they can also be used to identify the errors before the implementatio n of the process. Opinion It can be said that the creation of RSML model has enhanced the informal requirements and this process involved in verifying the formal properties helped in identifying the errors in both the RSML model and the original requirements. In real systems, there would be many requirements of these models. As a result, the models would be large as well as complex. These models need to be organized to be robust and readable in the changing phases and need to be reused. It is learnt that there are two known styles of the process of formal specification constructive and axiomatic specification styles (Lobet et al. 2015). Both the styles have advantages as well as disadvantages depending on the process of usage of the specification styles. However, the present day use of the tools of formal method is very useful, it can be used to solve the industrial problems, and they can be quite productive. Limitations The most important limitation of the system is the cost effectiveness. The initial experiments of the process of formal verification have been quite costly because of the use of techniques such as proving of theorem, which required significant time as well as expertise. The maximum cost was incurred on the creation of the RSML model of the Flight Guidance System. On the other hand, the constructive specification style has a disadvantage. It makes the readers biased towards a specific implementation (Yu and Lau 2012). Similarly, a specification, which is property oriented or axiomatic, can be more difficult and problematic to understand as well as write. Conclusion and Recommendations It is a very useful system and can be practically used. Therefore, the cost incurrence can be ignored keeping in mind the advantages of the system. The constructive system can be used in the basic programming languages such as Ada and C. It can be used for future use with few recommendations. Stronger techniques of abstraction will be required to decrease or reduce the problems and they can be further verified with the use of model checkers. The models need to be modified to identify the proof properties and strategies that can have an automatic generation from the model. References Acceituna, D., Do, H. and Srinivasan, S., 2014, May.

Structural consequences of the shift from technology

According to Gareth, 2010 technology-push which is a business strategy refers to a situation where new technological innovations are pushed via R and R, production as well as sales departments into the customers or the markets with no consideration or satisfaction of the end users.Advertising We will write a custom essay sample on Structural consequences of the shift from technology-push to demand-pull specifically for you for only $16.05 $11/page Learn More On the other hand, demand pull is a strategy in which innovation made by a business entity is purely based on the demands of the end-user. It has been thought that the later is the way forward for an organization to remain competitive in the current world of business. In the case of Sony and Guerrilla Games, there are structural issues of concern that arise in their quest to being a giant in the world of games. The four major design challenges include; vertical and horizontal differentiation, differe ntiation vs. integration, centralization vs. decentralization of authority and standardization vs. mutual adjustment. It is no doubt that the merger between the two organizations will bring about a conflict on whether to adopt standardized way of doing things or adopting a mutual adjustment approach. According to Gareth, 2010 it is worth noting that standardized although a good aspect of organizational structure, there will be need to ensure that it gives workers an opportunity to fully incorporate the ideas into the systems of coming up with better services and products. Despite the fact that it will help cut down cost as well as increasing reliability there are instances that standardization will bring about a forced way of ding things which may plunge the two organizations into trouble.Advertising Looking for essay on business economics?

Get your first paper with 15% OFF Learn More To curb this, there is need to resort in adopting mutu al adjustment where each of the organization will harmonized their differences and eventually share the same view points. Having in mind that decision making within an organization is of paramount significance especially considering time factor, a centralized environment of authority will pose a great problem to the firms as arriving at decision and giving direction might take a shorter time. Such decisions stand chances of being vague. Additionally this strategy gives very little room for consensus building; this may results to projects being arrived at without being fully agreed upon. On the other hand, decentralized authority brings with it a democratic working environment (Gareth, 2010). With this, views can be brought forth in an open manner hence supporting consensus building. However, it usually take more time to arrive at a decision since there will be involvement of a number of individuals as well as departments. Similarly, the issue of integration which typically is consid ered in terms of sharing information also arises when firms join forces. It is thought that integration bring a number of benefits regarding efficiency, agility, transparency as well as enhanced coordination. In situations where information is shared across a less hierarchy level, then it is evident that the information reaches the intended party within the right time frame for feedback to be provided. However, the approach make it time consuming when coming up with vital decisions. On the other hand the issue of growing into a complex organization comes into play. Such organization proves to be a challenge to manage.Advertising We will write a custom essay sample on Structural consequences of the shift from technology-push to demand-pull specifically for you for only $16.05 $11/page Learn More Lastly and more importantly, horizontal and vertical differentiation provides a challenge to the firms. In cases where the products produced are distinct in feat ures that cannot be ordered in an objective manner then horizontal differentiation will emerge. This comes in form of differences in differences in attributes of the products such as varying styles and tastes (Gareth, 2010). Vertical differentiation is applicable where one product is deemed better than the rest. With this in mind, orders are placed purely based on objective qualities. Reference Gareth, J. (2010).
