In IT, system logs are important in monitoring and troubleshooting. Extend the list class by creating a custom class LogList that manages a collection of log entries, where each entry is a string. Create a Child Class LogList: Inherit from list to create the new class LogList. There is not need to include a constructor statement. Implement the find_entries Method: Add a method, find_entries, that accepts a single parameter, keyword. This method should iterate over the list of log entries and return a new LogList instance containing only the entries that include the keyword. Hint: You can check if a keyword is in a string using the syntax keyword in entry, where keyword and entry are both strings. Example Usage: Although example usage is provided for clarity, you do not need to demonstrate its usage. # Creating an instance of LogList with sample log entries logs = LogList([ “Error: Disk full on server1”, “Warning: High memory usage on server2”, ]) # Finding entries that contain the keyword “Error” error_logs = logs.find_entries(“Error”) print(error_logs) # Expected output: [“Error: Disk full on server1”, “Error: Failed to connect to server4”]

Support your ideas with strong logic and information from the article. Avoid personal experience, and create a formal tone in your essay.    Freshman English I Midterm Exam Article: The Mental Health Crisis on College Campuses By: Mary Ellen Flannery, Senior Writer Published: March 29, 2023 https://www.nea.org/nea-today/all-news-articles/mental-health-crisis-college-campuses The majority of college students (more than 60 percent) meet the criteria for at least one mental health problem—a nearly 50 percent increase since 2013, according to the Healthy Minds survey, published earlier this month. Specifically, 44 percent of students reported symptoms of depression; 37 percent said they experienced anxiety; and 15 percent said they were considering suicide—the highest rate in the 15-year history of the survey. More than 90,000 students across 133 U.S. campuses participated in the survey. This mental-health crisis affects students of all races. White? Black? Hispanic? Or Asian? About two-thirds of college students of all races report they have felt “very sad,” according to a 2019 study. Similarly, about a third of college students—White, Black, Hispanic, and Asian—have felt “so depressed that they couldn’t function.” There is a difference among racial groups, however, in access to mental-health care. Specifically, White college students are almost twice as likely than Black students to get it, according to one study, which found that 46 percent of White college students sought mental-health treatment compared to 23 percent of Asian students, 26 percent of Black students, and 33 percent of Latino students. Stressed Out Students Can’t Do This Anymore The depth of these mental-health issues has become so severe that it’s affecting college students’ ability to persevere in their studies. Four in 10 college students have recently considered withdrawing from college, a study released last week shows. And the number-one reason why? “Emotional stress.” Emotional stress was cited by 69 percent of bachelor’s degree students and 55 percent of community college students, according to the report, “Stressed Out and Stopping Out: The Mental Health Crisis in Higher Education,” produced by Gallup and the Lumina Foundation. The second biggest reason was “personal mental health reasons,” (59 and 44 percent of bachelor’s- and associate’s-degree seekers, respectively), followed by “the cost of the degree program” (36 and 25 percent.) When asked what emotional stress means to them, many students told researchers that coursework can be overwhelming, especially in combination with jobs or caregiving duties. Some mentioned depression and anxiety, or concerns about paying for college. The report found that, on average, community college students were more likely than bachelor’s degree students to say they were thinking about withdrawing or taking a break from school because of those problems. “When You Have Stuff Going On…” These students sound a lot like the ones in Candace Shivers’ human services classes at Mount Wachusett Community College in Massachusetts. Many of them are taking care of siblings, working part- or full-time jobs, in addition to taking the classes that will help them someday get jobs in human services as nurses, social workers, addiction or mental-health counselors, case workers, etc. “When you have a lot of stuff going on, school becomes less of a priority,” says Shivers, an associate professor of sociology. Often, they get overwhelmed and fall behind. Sometimes, they disappear for a few weeks. Eventually, many find their way to her office where they burst into tears and tell her they can’t possibly catch up. She has learned how not to overwhelm them when they return. “When somebody comes to me and says they need to get caught up, I don’t give them everything that they need to do,” she says. “In my experience, giving them everything never works. We start with one thing. ‘Start here, get it in to me.’ And then I give them the next thing, like, “Okay, now do this and get it in to me.’ Shivers has been teaching for 19 years, and her thinking on this has evolved. A decade ago, she might have handed them the syllabus and told them to figure out what they had missed. Today, she calmly tells them, “It’s okay. Let’s talk about it.”   A Lack of Services While understanding, supportive faculty can help, most students need a lot more than that to meet their mental-health needs. Faculty aren’t trained counselors. And, complicating matters, many faculty are overwhelmed, too. Roughly two-thirds of faculty are, like Perez, working as adjunct or contingent faculty members. To make enough money to pay the bills, they often work part-time at multiple colleges or other jobs. They’re spread thin. And because they’re not working 30 hours at any one institution, they don’t get employer-provided health benefits. It’s hard for them to get their own mental-health care. Meanwhile, on-campus counselors who provide mental-health care to students are overwhelmed. In 2019—and this was before Covid-19—90 percent of counseling center directors reported an increase in students seeking services. Most wellness centers have waiting lists of several weeks to see an in-person counselor. The demand for services has led to burnout among counselors, and turnover is rapidly increasing, according to the center directors’ annual survey. “Administration might say the help is there, but students come back to us and say, ‘I couldn’t get in. Now what do I do?’” says Perez Making matters even worse, some colleges have sought to cut spending by cutting counselors’ jobs. “They said they were going to outsource [those services], but actually we saw faculty and adjuncts having to pick up the load,” recalls Lewis Jones, a union leader at Harrisburg Area Community College in Pennsylvania, where faculty responded by organizing a new union. Institutions need to spend the money—and they do have money—on supporting students and faculty, says Perez. “The whole organism is sick,” says Perez, referring to the higher education system. “You can’t just put a bandage on it.”        

ACG Inc. makes two types of paper shredders, a Home model and a more heavy duty Office model. ACG produces 60,000 units of the Home model and 12,500 units of the Office model.  The company’s conventional cost system allocates manufacturing overhead to products using a plant-wide overhead rate and direct labor dollars as the allocation base.  Additional information relating to the company’s two model lines is shown below: Home Office TOTAL Direct materials $360,000 $162,000 $522,000 Direct labor $140,000 $100,000 $240,000 The company is considering implementing an activity-based costing system that distributes all of its manufacturing overhead to four activities as shown below:       Activity Activity (and measure) Manuf.
