Explain the concept of muscle contraction based on neuroelectrical, chemical and energy sources

Explain the concept of muscle contraction based on neuroelectrical, chemical and energy sources.

Neuroelectrical Factor

Potassium ions are more prevalent within the muscle that they are outside, while sodium ions are greater on the outside. The inner part of the cells is negatively charged compared to the outside which is positively charged. When a nerve impulse reaches a neuromuscular junction, it causes the endings of the axons to release neurotransmitter acetylcholine (Rizzo 9-3a). The action therefore causes the cell membrane to become permeable to the sodium ions. The Na+ rush in making the potassium ions to rush out in an effort to restore the resting potential. Since the potassium ions are not enough compared to sodium ions, they are unable to restore balance.  The muscle cell therefore generates its own action potential that penetrates deep into the muscle fiber through the T-tubules. It resultantly causes the release of Calcium ion from the sarcoplasmic reticulum. The calcium ions are released to the fluids around the myofibrils. The calcium ions stop the actions of the inhibitor elements (tropomyosim and troponin) which cause the contraction process to occur.

Chemical Factor

The calcium ion combines lightly with myosin to form stimulated myosin, which reacts with ATP also attached to the myosin. The reaction releases energy to form actomyosin. Mysosin filaments pull and connect with the actin filaments causing an increase in the width of the Z lines to reduce but the A bands to remain the same (Rizzo, 9.4a).  At this moment, the sodium-potassium pump joins in to restore the resting potential. The Calcium ions are absorbed to stop the contraction process.

Energy Sources

Glycosis occurs changing glucose into pyruvic acid with a net gain in 8ATP if oxygen is present. When oxygen is absent then lactic acid forms but with a gain of 2 ATP. The Krebs Citric acid cycle then follows, which converts pyruvic acid into carbon 2 oxide, water and a total of 30ATPsPhospohocreaticn also occurs in muscles cells and the combustion of free fatty acids, all producing an extra ATP. The ATPs produced are use within the contraction process.

Abstract

The UK labor market has transformed greatly for only a year in 2020, and this calls for attention to any Human resource officer and aspiring candidates to pay close attention and readjust to the new norms. Covid-19 pandemic slowed down the economy thus slowing down employment, increasing redundancies, and reducing the overall working hours. Inclusivity employment has also gone down because of Brexit and Covid 19. Many of the immigrants coming into the UK have reduced because of Brexit and women workers have been more affected with Job losses because of Covid. The economy is also hosting the Baby Boomers, Millennials, and Generation Z at the same time currently. All three groups have different needs and need to be accommodated in the talent management practices. Technology is also fast-changing and staying behind would render businesses obsolete. Organizations, therefore, need to apply proper human resource planning techniques to deal with the labor demand and supply. They should be adept in appreciating changes and emerging trends to make their functions effectively. A Graduate seeking employment within the new era should work on improving their technological acuity, soft skills, and being flexible to make them competent for the roles.

 

 

 

Introduction

Every economic pundit would bear testimony that the UK labor market underwent a crisis in 2020. Statistics from the Office of National Statistics revealed several worrying trends. Employment, working hours, job vacancy rates went down drastically within the first two quarters of the year while redundancies increased. The major concerns came from Brexit and the Covid-19 pandemic which rendered many of the traditional talent management systems useless. Companies have had to bring in new technologies to ease communication and their functions and at the same time train workers fast enough to use them. Brexit has also rendered the labor market supplies to diminish and thus introduce a talent scramble. Gender and ethnic balance is still a problem that has not been sort out even in this generation of empowerment and affirmative action. The UK generational geography is also a problem that companies are fighting to balance in their day-to-day activities. The UK labor market has transformed greatly for only a year in 2020, and this calls for attention to any Human resource officer and aspiring candidates to pay close attention and readjust to the new norms.

 

Trends in UK Labor Market Between March 2020 and February 2021

Covid-19

The onset of Covid 19 to the UK economy was a twin pandemic because it affected the health of the labor market and the structure of the job within the economy. The lockdowns instituted within these periods resulted in many companies closing down and others applying different working measures such as working from home. Due to this, the number of payrolled employees reduced by 635,000 (Francis- Devine, Powell, & Foley, 2021, p. 9). The industries that experienced the largest falls were food services and accommodation, entertainment, arts, and recreation. The unemployment rates have also gone down significantly ((Costa, and Stephen Machin, 2020, p. 1). The younger generation between 16-24 were also the most affected people (Francis- Devine, Powell, & Foley, 2021, p. 9). Other statistics associated with Covid 19 included, reduction in overall working hours, drops in the numbers of job vacancies, and an increase in redundancies recorded ((Costa, and Stephen Machin, 2020, p. 1; Mayhew & Anand, 2020, pp 224;

Women and Diversity in Employment

In 2020, the number of women in employment above the ages of 16 was 15.49 million in the October-December quarter.  The numbers translated to a drop in the female employment rate from 72.4% in 2019 to 71.8% in 2020 (). Women also majorly in part-time employment at 38% compared to men at 13% (Dy, Jayawarna. and Marlow, 2020, p. 3). The average wages of the women were lower than men at £543 and £619 respectively. Corona Virus has also had a significant impact on women because, in the reported cases of job losses and redundancies, women’s numbers were higher than men’s. The ethnic minorities within the employment sector reduced in the year 2020. According to the office for National Statistics, the number of ethical minorities reduced to 3.697 million in the October-December quarter, down from 4.045 million people. The country’s reliance on ethical minorities for the semiskilled positions will cause a problem because of the reduction in these numbers after Brexit.

Brexit

The lowering of the UK GDP that stems from Brexit translated to the lowering of the level of employment opportunities in the UK in 2020. The many economical models about Brexit, all point out a loss in GDP compared to the initial status quo that the country enjoyed. The loss of jobs in 2020 resulted in a lowering of demand for UK goods within the EU (Javorcik, Stapleton, Kett, & O’Kane 2020, p. 21). The country has heavily relied on the service sector, which has also been our main export and job creator. As of the end of 2019, there a shrinking supply of labor and skills reported by the many companies experiencing recruitment difficulties (LMO, 2019.) The shortages would therefore be dependent on migrant workers coming from the EU. After Brexit, many EU-born workers left the UK and it left a gap between the low-skilled and medium-skilled workers. The migration effects on employment have not been fully experienced because of the travel restrictions implemented during the Covid period.

Generational Geographies

The unforeseen problem within the UK labor market is the threat of the Babyboomers. According to LMO, the labor participation rate for the baby boomers is high; more than 20% of people above 65years are either employed or actively seeking employment (Taylor, 2019). The Bureau of statistics on the other hand predicts that the over 65 workforces will continue growing. The threats posed by the baby boomers are that they are currently serving at top positions and preventing the progression of younger generations despite their higher sick pays and life assurance bills, they will also cause a brain drain upon retirement.

Generation Z and millennials on the other hand possess their troubles in talent management which also have to be addressed. T attract and keep these two talents, there is a need to increase flexibility in their job structures. They ant modernized offices, and they prefer the use of technology. Generation Z also has their preferences such as being collaborative other than competitive, are entrepreneurial, and are oriented towards salaries and job security. Dealing with the differences in needs for each generation poses a great problem as everyone has to be catered for.

Emerging Trends and Tech

            The workplace in the UK in 2020 faced a lot of disruption because Covid and work enablement was only possible through flexibility and the use of technology. Many had to work from home through teleconferencing and telecommunication applications which had to be learned on short notice. Even after the Covid-19 period, the same trend will follow and workers will expect reliance on tech and flexibility.  Several emerging trends have also been witnessed in each industry, thus forcing the market to change consistently to the needs. Talent management is therefore forced to consistently change and adopt these new trends to keep them afloat.

Responses that Organizations Have Made to the Trends

In response to Covid-19. UK organizations restructured their working environments to accommodate the new restrictions structures. Working from home was the first most viable option and they employed teleconferencing facilities to ensure everyone was at per with the others (Francis- Devine, Powell, & Foley, 2021, p. 10). The HR carried out a proper workload inventory and redeployed workers to critical areas of the organization. The redeployment was followed by a proper training program to help them fit into their new roles. Some roles were merged with others and some departments reduced or increased to suit the prevailing needs at the time (Caligiuri et al 220, pp1). All these efforts were in place to ensure people had as minimal contact as possible, the companies would save on costs and still manage to cater to their customers.

The shortages in labor in 2020 caused by Brexit and Covid-19 also forced many organizations in the UK to adopt a proper human resource planning technique. Companies are taking into account demand planning to determine the job roles they would need to fill; this is done by assessing the Hr capacity against the workload. The supply current is limited therefore organizations need to carry out an early supply forecasting to determine the sources of their next employees. At this point on, the Hrs would refine their talent strategies such as recruitment, hiring, training, remuneration, and performance management. When the right demand and supply forecasting is carried out, organizations can deal even with the shortfalls in the labor market.

UK companies are recognizing the fact that the majority of their workforce will have to re-skill in the next five years owing to the emerging technologies in IoT, Artificial intelligence, blockchain, and Machine learning. Many of these organizations are using mobile learning technologies as a just-in-time and easy system of delivering knowledge. Instead of traditional training, these are more personalized and use the LMS systems that can track individual patterns and tailor the content. The LMS system also identifies the skills gaps of the workers and plan for learning interventions. Technological methods are also used in the recruiting process to reduce bias and provide the right fit for the company. These same systems follow up with the employees to track their performances and device reward systems that are holistic. Technology systems have therefore been effective in keeping employees engaged consistently, monitoring their progress, training them often, and rewarding them for their progress.

 

Implications for resources and talent management

Talent management during the Covid-19 pandemic has been a difficult thing as there was no applicable playbook as each situation presented different sets of conditions. There have however been great lessons learned from the pandemic that would improve talent management in the future. The main lesson learned is to focus on employee wellbeing. The period showed organizations the importance of checking in with their staff, supporting them through hard times while investing more resources in covering their health and wellbeing (Eileen Aitken et al. 2020, pp1). Adaptation has also a key ingredient in the survival of many organizations during the season. HR has learned to focus on the adaptability of employees during the hiring process; this flexibility would help them learn and change within the job. Organizations have also had to accept that digital is a new reality (Niamh, 2020, pp. 1). During the pandemic, organizations have had to train and apply new digital technologies in conferencing, doing works, and meeting (Eileen Aitken et al. 2020, pp1).  It is now inevitable to dismiss the use of these platforms henceforth.

Implications to Graduate Employability in the UK Labor Market Today

It is time for graduates to embrace digital technology and online platforms because new technology has shifted many traditional functions into digital platforms. The technology is relied upon majorly to conduct business, Companies, therefore, had to adopt cloud-based communication, productivity tools, teleconferencing facilities among others (Niamh, 2020, pp. 1). The majority of these facilities had already been in existence but were rejected or ignored. A workplace-ready graduate should have the technological know-how to perform in their roles using these modern applications and be ready to embrace more that will come along.

Organizations are also now looking for a graduate who constantly evolves and changes. Organizations are not hiring necessarily for roles but are building a team for a career. In this way, they seek people who can change roles easily, take more responsibility and learn new things fast (Buheji, and Buheji, 2020, pp240). At the end of the day, the graduate who is more adaptable and those who can work within diverse teams are becoming more marketable. While not every graduate will have all the qualities required for such a time, the best candidates would be those who are ready to learn and those who are culturally fit.

The current talent market has further emphasized the need for certain soft skills within its workforce. The need for better communication and organization has become apparent because of the remote work. Employees have been required to share ideas, contribute actively in discussions virtually. Working from home has also required them to be well organized, create better schedules, and while at it manage the stress brought about by the period. Teamwork is also a major soft skill that has pushed the workers through because people had to work in smaller virtual teams to reach the targets (Buheji, and Buheji, 2020, pp240). These will be soft skills that employers will focus on when employing new staff post-Covid.

The modern job market is not ideal, and the timing also terrible. It however offers some opportunities for people to work and grow towards professional success. It is required that Graduates prepare well before rushing into jobs and applications.  They need to continuously learn new skills through online platforms and develop skills that would give them the edge. To practice their skills, graduates could also participate in volunteer work part-time opportunities, and projects (Gill., 2020, pp12). These would help them to develop the right frame of mind for a real working environment. It is also time for graduates to consider remote work as a viable source of employment.

Conclusion

Covid-19 pandemic slowed down the economy thus slowing down employment, increasing redundancies, and reducing the overall working hours. Inclusivity employment has also gone down because of Brexit and Covid 19. Many of the immigrants coming into the UK have reduced because of Brexit and women workers have been more affected with Job losses because of Covid. The economy is also hosting the Baby Boomers, Millennials, and Generation Z at the same time currently. All three groups have different needs and need to be accommodated in the talent management practices. Technology is also fast-changing and staying behind would render businesses obsolete. Organizations, therefore, need to apply proper human resource planning techniques to deal with the labor demand and supply. They should be adept in appreciating changes and emerging trends to make their functions effectively. A Graduate seeking employment within the new era should work on improving their technological acuity, soft skills, and being flexible to make them competent for the roles.

Refer to the supporting resources section below for information on how to record your script and share your link/upload your presentation.

  1. In most organisations, group and individual reward systems are required. The choice between individual and group rewards depends (to an extent) on the interdependencies that exist within the organisation. (2 slides – maximum of 4 minutes)
    1. Select one of the reward system propositions below.
    2. Justify recommendations for your chosen proposition and how that would satisfy these interdependencies and be implemented in your organisation.
Proposition 1 The organisation’s reward system directly aims to motivate individual employee performance to be consistent with current organisational strategy. This means that employees and managers are individually rewarded through a rewards scheme that recognises individual performance and accountability. Examples: meeting individual sales targets (growth strategy), reducing machine idle time (cost control strategy), reducing customer complaints (quality control strategy).
Proposition 2 The organisation’s reward system aims to motivate employees to share and strive towards the organisation’s vision and mission (sometimes referred to as values and beliefs).  In this proposition, all employees and managers benefit collectively by introducing a bonus or dividends scheme that is based on the overall share price (if a listed company), revenue or net profit of the organisation. Examples: A lump sum of $2,000 for the year to each employee, a one-time bonus payment or dividend of 2% of their salary to all employees.

Research in to the use of Stack overflow for security

Research in to the use of Stack overflow for security

Purpose

This task forms part of your assessment, the data which you capture will also be used to write a research paper. The use of the data for research purposes is purely voluntary. You will be asked to complete a consent form and will have until the start of semester 2 to withdraw your consent. You may also withdraw or not permit the use of the data you capture to be used in the research, you will not have to giving any reason and doing so will not have any consciences for yourself.

 

This exercise should not take more than an hour to complete and it will be undertaken in the lab during before week 11. There are four tasks in total, they need to be done in sequence and once completed they should not be amended based on the subsequent tasks. It is also vital that tasks 1 to 3 take place before week 11 lecture, and that task 4 be completed after week 11 lecture. Details on how to submit the work will be given later, however it will be collected in prior to the end of semester. You should also submit the work as part of the assessment.

 

You will be asked to conduct some research on Stack Overflow (not other websites), the nature of the research is specifically related to the way passwords are stored for authentication purposes.  This is a very well known area of security and most developers will have had some exposure to creating a secure logon. The research should not encompass the following; TLS/SSL or password strength criteria. It should only be concerned with the way the password will be processed prior to being stored on a database for the purposes of user authentication. This is often described as a ‘cryptographic transformation’, i.e. transforming it from an insecure string into a secure binary format.

The current best practice will be discussed in week 11 therefore it is vitally important that first part of the investigation is done prior to this lecture otherwise it will contaminate the results of this study, and render the results useless. Equally it is important that the last task is done after the security lecture of week 11.

The main purpose of this research is to evaluate the effectiveness of stack overflow in providing a solution to a common security problem, and how prior knowledge affects the effectiveness of searching and finding an appropriate solution. It is therefore important that you capture your usage of Stack Overflow during the investigation.

 

Your job is to find the most appropriate technical solution for the problem of password storage. I will ask you to record the pages you look at on stack overflow (URL) along with information about the usage of the page: (percentage read, whether you fully read the page or skim read the page, and weather you found the page useful and relevant).

The Problem.

Single factor authentication relies heavily on the use of passwords to authenticate users. Although other authentication techniques do exist single factor password authentication is the mainstay of the e-commerce and commercial arena. As previously stated you are not asked to look at the security of the connection between the client and the server(TLS/SSL) and you are not being asked to look at policy such as frequency of password change or criteria for password strength. You are however, being asked to identify the technical solution for the transformation from a clear plain text string into the binary format which will be stored on the database. There are various ‘cryptographic’ transformations that can be used, some are keyed, some are none keyed, and some are reversible while others are not. The purpose is for you to choose the most appropriate cryptographic transformation.

 

The following is a list of tasks you have been asked to complete. Please note some information will be used about your prior experience however no information regarding your name or student ID will be stored. The information is relatively generic and therefore is anonymous in nature.

  • Task A ) Captures information about your background as a developer. Including any industrial experience you have gained.
  • Task B ) Captures any prior knowledge and/or preconceptions you may have regarding password security.
  • Task c) Before the lecture on security. Investigate the problem, capturing information about the pages you look at and proposed solution based on investigation.
  • Task d) After the lecture on security. If you believe you have already chosen an optimal solution you need to write in the section (OPTIMAL SOLUTION ALREADY FOUND) else use stack overflow again and repeat the activity of undertaken in task C.

Part B)

 

Pre-existing knowledge of password security may improve your ability to search and sort for a solution on stack overflow. Therefore, it is important that you state any prior knowledge/preconceptions you have regarding the transformation a string password should go through prior to being saved on a database.

For example, I believe that the password should go through a ……….….. prior to being saved in the database. OR I really have no idea what should be done.

 

 

 

 

 

 

 

 

Part C) Task

 

The problem, passwords are a necessary part of user authentication although other mechanism to exist they are typically not viable for most computer systems and web application. There are a number of different technical solutions to storing password information for the purposes of user authentication.  Your task will be to find which one you believe to be an optimal technical solution, you do not need to code this but you do need to indicate which techniques would be used to store the password securely. The resource you need to use for this task is the popular developer site Stack Overflow. For each page you look at, you need to record the URL and the following information. I expect that there will be a number of pages you will look at before you decide on a solution. Please place them in chronological order of when you viewed then. Starting with the first page at the beginning, add then in chronological order with the final URL and the end.  In case of missing URL or out of sequence documentation of the process, please open your browser history and cut-and-paste the section related to stack overflow at the end of this section.

KF7014 – Advanced Programming & KF7012 – Implementing Object Orientated Design

Task 1 Research Question (Individual Work)                             30 marks                                                      

This task is an individual task and covers the following learning outcome.

  1. Demonstrate in depth knowledge and understanding of current best practice in the design and development of Object Orientated systems

 

Question for section one and two

 

“Most systems require user authentication, identify the technical approach you would use to storing the password information so that a user was able to authenticate themselves at a later date. You discuss a range of approaches and any weaknesses with the indentified approaches.”  

 

 

The research is split into three sections,

 

Section one

The initial part you will be limited in your usage to a single source of information, namely “stack overflow”. This initial investigation should take approximately 1 hour to complete. And will be undertaken during the lab session. See Appendix B for information regarding how to capture the information. If you miss the lab you can still do the exercise and forward the information to the module tutor for analysis.

                                                                                                                        (5 marks)

 

Section two

This second part answers the same question however it should be only done after the lecture on security. You must document the work in the same way as you did for section one, using the layout from Appendix B. Part one documented finding information on stack overflow in this section. You also need to write a short summary identifying the technical measures you would take and give a reference to any code examples which you would use as a basis for implementing the solution.

                                                                                                                        (5 marks)

                                                                                                            Word Limit 300

 

 

Section three 

Identify possible technical solutions to security protecting information in the properties of a class prior to it being persisted on a database.  Additionally you should consider and outline any implications any of the possible solutions may have on the winder functionality or performance the application.

(20 marks)

                                                                                                            Word Limit 1500

 

References from good-quality, relevant literature must be used in order to strengthen any points that you raise in your discussion. This only relates to sections two and three of this question.

 Task 2 UML Designs and OOP considerations (Group work)  10 marks

This task assesses the learning outcome.

 

Design a system using advanced object orientated principles and methods, such as Behavioural, Creational and Structural design patterns, ensuring a high level of quality and data security.

 

 

Produce an implementable class diagram for the system you are developing, this should show your final design of the software components and clearly show architectural patterns used in the development of the system. It should not be post implementation diagram created by visual studio. You are expected to use Design Patterns in the creation of you product, and you are also expected to show layering of the application, patterns should be considered in each of the layers for example you are expected to use a presentational Patten in the interface layer. This work should only include the requirements which you are expecting to implement during the time-box.
(5 marks)

 

You must provide a justification for any of the patterns you have chosen to implement. Outlining reasons why the choices have been made. You should also include any patterns which you believe could be beneficial to the software architecture, but which you decided not implement. A rational for their exclusion should be given.                                      (5 marks)

Word Limit 300

 

 

 

Task 3 Implementing the technical Solution (Group work)                 20 marks

In this task the following learning outcome is assessed.

 

 

Implement and test Object Orientated programmes using advanced techniques ensuring a high level of quality and data security.

 

You are not expected to try and implement the entire system. Agile methods require a subset of requirements to be taken into a time-box for development. You can apply MoSCoW to list of requirement, this will help you decide on what requirements you plan to implement. However you are expected to pick requirements which work together so that you can demonstrate a working subsection of the entire system, you should use vertical development.

 

You are expected to develop the application using the standard three layer model and the domain and presentation layer should contain some of the patterns covered in the module.

 

Entity Framework must be used to persist the objects. It is your choice on how you use the technology. It is recommended not to use Database first as this will have architectural consequences to your system.

 

The system must be implemented using Visual Studio 2017 or 2019 and be written in C#. As stated earlier only windows forms may be used and the application must use the inbuilt database.

You may include instructions as to use which would include any valid logon details or user details that you have created.

The code is marked on the following aspects:

 

 

Scope technical implementation                                                                     (5 marks)

 

Quality of the solution, including architecture patterns used.                                                                                                                                                                        (13 marks)

 

 

 

Task 4 Testing (Group work)                                                                                 10 marks

In this task the following learning outcome is assessed.

 

  1. Demonstrate a professional understanding of the importance of software quality in the development of applications.

 

It is expected that there is sufficient level of unit level testing within the layers of the application. It is important that each class and method has an associated testing component. You should also carry out some testing at system level making sure that the system performs the needed system functionality. You should use both positive and negative testing.

Visual Studio provides an inbuilt testing framework, you are expected to automate as many of the tests as possible using the inbuilt unit testing framework.  If you have used dependency injection/mock objects to isolate classes you should make this clear in your testing strategy.

 

All tests must also be documented in a test plan, it is not enough to just have test project, it must documented in a plan.

 

 

 

Task 5 Evaluation of the development process (Individual Work)
15 marks

In this task the following learning outcome is assessed.

 

  1. Critically evaluate the effectiveness of implemented Object Orientated applications
  2. Demonstrate a professional understanding of the importance of software quality in the development of applications.

 

Many iterative methodologies incorporate an evaluation step at the end of each development time-box.  The purpose is to reflectively evaluate the development increment so that lessons can be learned, and improve the development process in future increments.  In this section you are required to critically evaluate development process and the tools used.

 

Approximately 700 words

 

Task 6 Evaluation of the technical solution (Individual Work)
15 marks

 

 

In this task the following learning outcome is assessed.

  1. Critically evaluate the effectiveness of implemented Object Orientated applications

 

Critically evaluate the Design and Implementation in relation to the object orientated principles covered in the module. You must consider the patterns you have used and discuss if they were effective and also identify any patterns you have not implemented but believe to be relevant.

 

Discuss the choice of Data Access implementation. Was Entity Framework directly used or did you impose your own unit of work and repository patterns. You need to justify and reflect on the choice you made.

Critically evaluate your application in terms of security. You do not need to discuss password security which you covered in the research question. However you should focus on the security needs of the application from the data perspective. You should use what you discovered from task one section three in order to give some specific recommendation related to this application.
