Linux Administration Question: 1. User evanhalen left, and I need to remove his account from my server and remove his home directory, but I also want to create a backup of all files in evanhalen\'s home directory and save that to my ~/backups directory. What SINGLE command would do this? Solution I have used the tar utilities to create a backup of users home directory as follows: Tar utilities means - The Linux “tar” means for tape archive, which is used by large number of Linux administrators to deal with tape drives backup. The tar command used to bind a collection of files and directories into highly compressed archive file commonly called tar in Linux Single line Command is below : # tar jcvf /my-backups/evanhalen-home-directory-backup.tar.bz2 /home/evanhalen.

What is the microevolutionary perspective , What is the basic connection between microevolution and larger-scale evolutionary change? Solution Microevolution refers to varieties within a given type.Change happens within a group,but the descendant is clearly of the same type as the ancestor.The small or microevolutionary changes occur by recombining existing genetic material within the group.Microevolution refers to the changes in allele frequencies within a singlepopulation.Allele frequencies in a population may change due to four fundamental forces of evolution i.e,natural selection,genetic drift,mutations and gene flow. Evolutionists assume that the small,horizontal microevolutionary changes lead to large, vertical macroevolutionary changes.Evolution that results in a large change and results in the formation of higher taxonomic groups is macroevolution.Macroevolution can not be observed directly,but is instead studied through the examination of fossils and the similarities and differences in the anatomy of organisms. According to modern synthesis,macroevolution results from the gradual accumulation of microevolutionary changes..

\"If the accounting is based on culture and is national , in fact, local cultures are different, international harmonization will be obviously impossible.\" Argued in detail either in favour or against such claim. Solution If the accounting were based on culture or were national, it would be impossible for international harmonisation. Every place on the world has got it\'s own culture, language, thought process which will have a direct impact on the accounting followed by it. Thus every community of people will have different accounting system. Thus it would never be possible to harmonise the accounting system of one place with that of other\'s due to existence of numerous differet systems..

Hello, I need help with the following assignment: This assignment will give you practice in manipulating lists of data stored in arrays. 1 General Instructions Read the general instructions on preparing and submitting assignments. Read the Counting Words problem description below. Implement the histogram function to complete the desired program. You must use dynamically allocated arrays for this purpose. For your initial implementation, use ordered insertion to keep the words in order and ordered sequential search when looking for words. Note that the array utility functions from the lecture notes are available to you as art of the provided code. Although we are counting words in this program, the general pattern of counting occurrences of things is a common analysis step in laboratory work, statistical studies, and business tasks. The results of such a program are often fed into other programs for further processing and/or display. Such results are often displayed as histograms. The CSV output format is a common “data exchange” format recognized by many programs. Almost all spreadsheets, for example, will read CSV files. When you have the program running, execute it using a short paragraph of text as an input, saving the output in a file ending with a “.csv” extension. Run a spreadsheet program (e.g., Microsoft Excel). You should be able to load your .csv file directly into the spreadsheet. Try displaying your results as a histogram. In Excel (2007), for example, select the two columns of data, choose “Sort” from the Data tab and sort your data on the numeric column. Then, with the two sorted columns of data still selected, go to the Insert tab and select a 2D Bar chart. Save your spreadsheet in Excel (.xsl) format. You will turn this in later. As documents get larger, the total number of words increases far, far faster than does the number of distinct words. Our personal vocabularies are only so large, after all. In fact, most writers unconsciously limit themselves to writing with a small fraction of their personal “reading” vocabularies. So most words in a large document are bound to be repeats. That means that, for this application, the speed of the functions for searching for words is probably more important than the speed of the functions for inserting new words into the array. We do many more searches than insertions. Try running your program on one of the large text files provided in the assignment directory. Time it to see how long it takes. Now replace all uses of ordered sequential search by calls to the binary search function. Run it on the same output, timing it again. You should see a substantial improvement. Use the button below to submit your completed program and your saved spreadsheet. 2 Problem Description 2.1 Counting Words Develop a program to prepare a list of all words occurring in a plain-text document, counting how many times each word occurs. In determining whether two words are different, punctuation (non-alphabetic.

From General Motors company’s financial information, what type of pension plan does it have? Discuss the reasons why your company has chosen this particular plan. What was the effect of the pension plan on General Motors company’s financial statements? Defend your response. Your CEO has informed you—the controller of General Motors company—that the board of directors has made the decision to look at other options of types of retirement plans. Investigate what other alternatives would be available, and determine which would be appropriate for your particular company. Solution Types of Pensions Employment-based pensions A retirement plan is an arrangement to provide people with an income during retirement when they are no longer earning a steady income from employment. Often retirement plans require both the employer and employee to contribute money to a fund during their employment in order to receive defined benefits upon retirement. It is a tax deferred savings vehicle that allows for the tax-free accumulation of a fund for later use as a retirement income. Funding can be provided in other ways, such as from labor unions, government agencies, or self-funded schemes. Pension plans are therefore a form of \"deferred compensation\" Social and state pensions Many countries have created funds for their citizens and residents to provide income when they retire (or in some cases become disabled). Typically this requires payments throughout the citizen\'s working life in order to qualify for benefits later on. A basic state pension is a \"contribution based\" benefit, and depends on an individual\'s contribution history. For examples, see National Insurance in the UK, or Social Security in the United States of America. Many countries have also put in place a \"social pension\". These are regular, tax-funded non- contributory cash transfers paid to older people. Over 80 countries have social pensions.[4] Some are universal benefits, given to all older people regardless of income, assets or employment record. Examples of universal pensions include Zealand Superannuationand the Basic Retirement Pension of Mauritius Most social pensions, though, are means-tested, such as Supplemental Security Income in the United States of America or the \"older person\'s grant\" in South Africa. Disability pensions Some pension plans will provide for members in the event they suffer a disability. This may take the form of early entry into a retirement plan for a disabled member below the normal retirement age. Benefits Retirement plans may be classified as defined benefit or defined contribution according to how the benefits are determined.[8] A defined benefit plan guarantees a certain payout at retirement, according to a fixed formula which usually depends on the member\'s salary and the number of years\' membership in the plan. A defined contribution plan will provide a payout at retirement that is dependent upon the amount of money contributed and the performance o.

Explain why it is more accurate to measure short rather than long map distances. Solution linkage map refers to a map of genes on a chromosomes based on linkage analysis.Linkage maps shows the relative position of a gene on the chromosome rather than their physical distances.It shows the relative position of a gene as determined by how often the genes are inherited together. Closer the genes more are chances of them being inherited together. Linkage maps are more accurate when the distance between the genes is shorter this is mainly because the chances of multiple cross overs becomes less to the close proximity of the genes , whereas in genes that have larger distances between them there are multiple cross overs and hence it becomes less accurate..

Explain the importance of both individual and group/team differences in an organization’s makeup. Solution Importance of Individual = an organization, by its most basic definition, is an assembly of people working together to achieve common objectives through a division of labor. An organization provides a means of using individual strengths within a group to achieve more than can be accomplished by the aggregate efforts of group members working individually. Organizational theory studies provide \"an interdisciplinary focus on a) The effect of social organizations on the behavior and attitudes of individuals within them, b) The effects of individual characteristics and action on organization,\'¦ c) The performance, success, and survival of organizations with cooperation of every individual. d) The mutual effects of environments, including resource and task, political, and cultural environments on organizations and vice versa, e) Concerns with both the epistemology and methodology that undergird research on each of these topics.\" Team composition=It refers to the overall mix of characteristics among people in a team, which is a unit of two or more individuals who interact interdependently to achieve a common objective. It is based on the attributes among individuals that comprise the team, in addition to their main objective. Team composition is usually either homogeneous, in which all members are the same, or heterogeneous, in which team members all contain significant differences. It has also been identified as a key factor that influences team performance. It factors in the individual attributes of team members (e.g. skill, experience, and ability) and how these contributions can potentially combine to dictate overall performance outcomes for the team. In the past decade, research on team effectiveness has burgeoned as teams have become increasingly common in organizations of all kinds. Research conducted on this topic has focused on aggregated member characteristics, member heterogeneity and team size as categories associated with team composition .The fashion in which a team is configured has a strong influence on team processes and the outcomes that the team achieves .The main outcomes associated with team performance can be classified mostly as performance outcomes (overall quality/precision of work produced, etc.) internal member outcomes (group cohesion, etc.) and behavioral outcomes (absenteeism, etc). The team composition determines the array of knowledge, skills, and abilities within a team. The compositional distribution of team members on any social or psychological attribute that potentially leads to the perception that team members differ from one another, are typically driven by how members process information, such as a diverse set of knowledge, skills, and abilities to solve complex problems. Knowledge includes the facts and principles that apply to the domain of the team. Skills can be either basic or cross-functional. Ba.

Discrete Probability A fisherman catches fish at a Poisson rate of two per hour from a large lake with lots of fish. If he starts fishing at 10 AM, what is the probability that he catches one fish by 10.30 AM and three fish by 12 PM? Solution As we are given that fisghes catches at poisson rate (2 fishes in 1 hour). Thus probability of caching n fishes at time t [p(N(t) =n)] = [{ e^(-lamda * t) } *(lamda *t)^n] / n! where lamda = 2 probability that the 1 fish catches by (1/2) hour is p(N(1/2) = 1] p(N(1/2) = 1] = [{ e^(-2 * 1/2) } *(2 *1/2)^1] / 1! = e^(-1) =0.367879 probability that the 3 fish catches by (2) hours is p(N(2) = 3] p(N(2) = 3] = [{ e^(-2 * 2) } *(2 *2)^3] / 3! = [{ e^(-4 } *(4)^3] / (3*2) = 0.195367.

4. Would have your ancestry traced using DNA? Why/why not? Solution Ancestry tracing by DNA relies upon small tandem repeats in the DNA sequences. One may go for checking the ancestry using DNA because: 1. It is a fool proof technology 2. It helps us to understand the history and the migration pattern of our ancestors 3. It helps to bridge emotional gaps between the races. The similarity in the DNA sequences of different races is a gentle reminder that we all are humans..

These E2F proteins are involved in the transcription of RNA or DNA to proteins and cell cycle regulation in higher eukaryotes. E2F family has a DNA binding region or motif and generally these region are alpha helical in nature. Proteins generally have three secondary structure components and are alpha helical, beta sheets and turns other than the randomness in the sequence. coming a step back proteins are actually divided as having primary structures like amino acids in a sequence, secondary structures like described above and tertiary structures like the hydrophobic or hydrophilic areas in the proteins formed due the aromatic and charged aminoacids present. Also quartrnary structures which comprises of domains and higher order structures. Alpha helices are significant in DNA binding motifs as a alpha helix fits into the major groove of the DNA. Considering this a few aminoacds can be present in the helices like Ala,Leu,Met,Phe,Glu,Gln,His,Lys,Arg. these aminoacids can form intra strand hydrogen bonding and amino acid side chain should cover and protect the backbone H-bonds in the core of the helix. these aminoacids have to be having charged side chain reactive groups for interactions. we can provide the following sequence of 13 aminoacids based on the above justification Ala,Leu,Met,Phe,Glu,Gln,His,Lys,Arg, Ala, Phe, Gln, Met, Ala, Leu,His,.
