Concentric: Literary and Cultural Studies 33.1 March 2007: 75-85 Nervous Tracery: Modern Analogies between Gothic Architecture and Scholasticism Joseph C. Murphy Fu Jen Catholic University Abstract During the Gothic revivals of the nineteenth and early twentieth centuries, Gothic architecture shed the morbid associations attached to it in earlier periods and was admired for the aesthetic and theological vision that shaped its medieval development. The Gothic cathedral came to epitomize the wholeness of the Middle Ages and an impulse toward synthesis in theology as well as the arts. This essay surveys four Gothic revival texts that define a relationship between medieval Gothic architecture and Scholastic theology: John Ruskin’s essay “The Nature of Gothic” in The Stones of Venice (1851- 53); Henry Adams’ Mont Saint Michel and Chartres (1904); Wilhelm Worringer’s Form in Gothic (Formprobleme der Gotik, 1911); and Erwin Panofsky’s Gothic Architecture and Scholasticism (1951). In these widely read works, influential beyond the field of art history, the seemingly arcane analogy between the Gothic and the Scholastic becomes a proving ground for the projects of prominent intellectuals within distinct historical and cultural contexts. For each author, the meaning of the Gothic hangs in a particular balance between its tracery—that is, its naturalistic ornamental detail—and its larger structure: the balance between the concrete and the abstract, between multiplicity and unity, also achieved in Scholastic theology. Because their analogies between the Gothic and the Scholastic isolate distinct lines of force within these complex systems, Ruskin, Adams, Worringer, and Panofsky each identify different values there, revealing as much about the modern mind as about the medieval. The syntheses that their medieval forbears accomplished collectively in service of faith, these interpreters seek independently in service of their own cultural identity, aesthetic values, or intellectual coherence. Keywords Gothic architecture, Scholasticism, John Ruskin, Henry Adams, Wilhelm Worringer, Erwin Panofsky, Thomas Aquinas Concentric 33.1 March 2007 76 The Gothic style presents an interesting case of how the Middle Ages have persisted in Western history through the backward glances, sometimes leery, sometimes wistful, of subsequent periods. First arising in the seventeenth century as a derogatory term for the anti-classical, “barbarous” style adopted by European cathedral builders beginning in the twelfth century, the word “Gothic” became attached in the eighteenth century to a type of sensational narrative set in infelicitous buildings. During the Gothic revivals of the nineteenth and early twentieth centuries, Gothic architecture shed its morbid associations and was admired both for its aesthetic form and for the integral relationship of that form to a theological vision.

Con: Should the United States government have bailed out the automobile industry? Introduction A. In 2009, the .“Big Three” (GM, Chrysler, and ford) were facing fmancial struggles. They were fuced with a decision: either try and work through their problem on their own by securing loans, or to go to the government for help. Of the Big Three, only Ford declined government assistance, having already secured a line ofcredit in 2006 by using all of their assets as collateral. GM and Chrysler filed for a managed Chapter 11 bankruptcy that was funded primarily through the U.S. Treasury using taxpayer money. This modified version ofChapter 11 bankruptcy that was implemented by the U.S. government appeared to have allowed these automakers to survive for the time being, but it came at the expense ofthe taxpayers and it did not address all ofthe problems that caused the Big Three’s issues in the first place. I. The Big Three’s poor managerial choices created their financial problems, and the taxpayers’ money shouldn’t be bailing them out. A. GM, Chrysler, and ford continued to focus on and mass produce large trucks and SUVs because of their higher profit margins despite a growing concern over increasing fuel prices between 2002-2007. 1. Research done by Thomas Klier of the Federal Reserve Bank of Chicago indicates that during the span of 2002-2007, “about 40 percent of the decrease in U.S. market share has been caused by the recent increase in the price of gaso line.” 2. More specifically, research done by Meghan Busse and F brian Zettlemeyer of Northwestern University and Christopher Knittle of UC Berkeley showed that through the period of 1999-2006, “a$1 increein goIinepricewiII decree the market share of cars in the least fuel efficient quartile (< 17.7 MPG) by 11.5%.... that a $1 increase in gasoline price will increase the market share of cars inthemofu effidentquatile(>24.3MR3) by 15.1%” B. They allowed legacy costs to build by continuing to give out large pension plans when foreign auto makers were switching to more realistically defined contribution plans (4OlKs) back in the $Os. 1. The average per-hour base salary ofa U.S. auto worker and a foreign auto worker were about the same ($28/hour in 2007) but each worker actually cost $73.21/hour compared to $44.17/hour of Japanese competitors, with the difference being the additional benefits promised. C. U.S. autornakers should have switched to defined contribution plans (4OlKs) in order to stay competitive and keep costs sustainable. 1. GM didn’t officially freeze their pension plans until February of2012. a. This meant that they would no longer contribute to the pension plans of workers who were promised them upon employment. Those employees would now receive 4OlKs (defined contribution plans), a change that should have been made decades ago to avoid current financial struggles. II. There was no market failure and the U.S. auto makei should have filed for traditional Chapter 11 bankrup.

computerweekly.com 10-16 September 2019 21 Industry experts believe blockchain is a technology that has the potential to affect the business of most IT profession-als in the next five years. Analyst Gartner has forecast that by 2023, blockchain will support the global movement and tracking of $2tn of goods and services. It is regarded by many industry watchers as a disrupting force in the financial world. A PwC global financial technology (fintech) survey found that 56% of respondents recognise the importance of blockchain. At the same time, however, 57% admit to being unsure about or unlikely to respond to this trend. Start witH tHe HaSH Blockchain is effectively a shared ledger between a group of people – for example, a group of companies that work together to produce a service or product. What makes blockchain different is the fact that the history of the changes – past transactions, for example – are immutable. Essentially, the historical entries become read-only and unchangeable. This is due to the fact that each blockchain entry relies on the hash – a computed value including part of a previous block as part of its hashing calculation for the current block. This means that if a previous block is somehow modified or corrupted, its hash value will change and therefore the values after that point become broken, making the tampering evident for all to see. One example where blockchain technology can be used is where several companies come together to provide or consume Blockchain: hype vs reality Regarded by many as a disruptive force in finance and beyond, blockchain technology presents a number of complex challenges that must be overcome before it can truly deliver on its promises.

Fifty-one preteens spent five days at an overnight nature camp where television, computers and mobile phones were not allowed; this group was compared with school-based matched controls (n = 54) that retained usual media practices. Both groups took pre- and post-tests that required participants to infer emotional states from photographs of facial expressions and videotaped scenes with verbal cues removed. Change scores for the two groups were compared using gender, ethnicity, media use, and age as covariates. After five days interacting face-to-face without the use of any screen-based media, preteens’ recognition of nonverbal emotion cues improved significantly more than that of the control group for both facial expressions and videotaped scenes. Implications are that the short-term effects of increased opportunities for social interaction, combined with time away from screen-based media and digital communication tools, improves a preteen’s understanding of nonverbal emotional cues. � 2014 The Authors.

The intended outcome of this increased IT-facilitated student engagement is to foster important skills such as critical thinking used in both academia and workplace environments. Critical thinking (CT) skills entails the ability(ies) of mental processes of discern- ment, analysis and evaluation to achieve a logical understanding. Critical thinking in the classroom as well as in the workplace is a central theme; however, with the dramatic increase of IT usage the mechanisms by which critical thinking is fostered and used has changed. This article presents the work and results of critical thinking in a virtual learning environment. We therefore present a web-based course and we assess in which parts of the course, and to what extent, critical thinking was perceived to occur. The course contained two categories of learning modules namely resources and interactive components. Critical thinking was measured subjectively using the ART scale. Results indicate the significance of ‘‘interactivity’’ in what students perceived to be critical-thinking-oriented versus online material as a resource. Results and opportunities that virtual environments present to foster critical thinking are discussed. � 2012 Elsevier Ltd. All rights reserved. 1.

Computers are often used to make work easier. However, sometimes computers can make work more difficult especially with poorly implementation. SOX is an important example of a poorly implemented database that has encountered. A database should have its specific intentions as much as data organization and management always exist as general functions. The SOX database implemented in 2011 was put in place to combat fraud by coming up with efficient accounting audit and management of financial records. I think the developers failed to include technical aspects of fraud control into the system. They instead targeted the visible crimes leaving very many holes for exploiting the SOX system (Anand et al., 2014). The database seems vague from IT perspective. The database constitutes only two sections of codes relating to IT. These two sections merely meet the standards for testing IT sufficient auditing compliance by organizations. The database seems to be far off the role of fostering sufficient auditing process for these organizations. Since inception, most audit companies struggle to figure out the IT protective aspects of the database. It seems that the developers mainly focused on the guidelines in using financial systems in preventing frauds but rather forgot the IT aspect if reducing the vulnerability of the system. For so many years, the database has failed to meet the technical roles of a database in system management and accounting regulation which are the critical reason why it was created. The SOX guidelines seem to forget about pertinent technical aspects of the system function (Cinarkaya et al., 2017). The solutions to the mistake that was done are conducting technical analysis and installing appropriate fixing. Ideally, the database should target electronic management and safety of data rather than physical data management. This mistake of poorly implemented gave a false impression of database management in many companies that adopted the type of database in early days. From physical outlook, one could see that things are alright yet some technical rot was brewing within the system. It is clear that the developers of the SOX database missed some point while deriving and implementing the database and this should be fixed to enhance the computer-based operations (Anand et al., 2014).

Computer Science Terms Need To know About Have you ever spent time with a group of computers or IT professionals talking about the store? Terms like "LAN", "RAM" and "bandwidth" entered the conversation and you had no idea what that meant. It can be a little intimidating to hear all that tech jargon thrown around. But don't let a small language barrier stop you from enrolling in computer science terms . Just because you're new to the game doesn't mean you need to be left out of the conversation. With a little preparation, you can impress your classmates on the first day of school with your computer know-how. To get you started, we've compiled this basic list of computer terms you should decode before setting foot in class. Brush up on this common vocabulary and you'll be up to speed with your tech friends' conversations in no time. 25 computer terms you need to know Each industry has its own jargon, and computing is no exception. Become familiar with these 25 computer terms to impress your classmates and teachers from day one. 1. Analog Analog technology is any part of the technology that does its job without processing numbers electronically like a computer does. You might think of analog as "old school" technology, like movie cameras or tape recorders. 2. Bandwidth This term refers to the amount of information that can be transmitted or processed, wirelessly or over a wired connection. Internet services will advertise high speeds measured in bandwidth, so it is a well known component of the IT world. 3. Big data Big data is a quick way to refer to the huge amounts of data that companies collect on a daily basis. Businesses face a number of big data management challenges, especially when it comes to analytics and security. 4. Bit Bit stands for "binary binary", the smallest piece of information used by a computer. Each piece is 1 or 0, which are binary numbers that make up a computer language. Pieces are literally the foundation on which computing is built. Because they are so small, computer wizards require basic technology to think of pieces on a larger scale: Byte = 8 beats Kilobytes = 1024 bytes Megabytes = 1024 kilobytes Gigabytes = 1024 megabytes 5. Bugs A bug is a programming error that causes wisdom or unexpected problems for the end user of a program. 6. Cloud storage Cloud storage is another way to store data in the physical memory of a computer. Information stored "in the cloud" is stored on remote servers that can be accessed anywhere over the Internet. 7. Code Code refers to various programming languages used to create, modify or manage computer programs or applications. Most computer science students specialize in a handful of programming languages depending on the career they would like to pursue. 8. Control panel Just as it sounds, the control panel is a tool that allows you to change or modify the program's settings as it looks or behaves. 9. CPU CPU stands for Central Processing Unit, which i.

Computer Fraud and Abuse Techniques Chapter 6 6-1 Copyright © 2015 Pearson Education, Inc. Copyright © 2015 Pearson Education, Inc. 1 Types of Attacks Hacking Unauthorized access, modification, or use of an electronic device or some element of a computer system Social Engineering Techniques or tricks on people to gain physical or logical access to confidential information Malware Software used to do harm 6-2 Copyright © 2015 Pearson Education, Inc. Hacking Hijacking Gaining control of a computer to carry out illicit activities Botnet (robot network) Zombies Bot herders Denial of Service (DoS) Attack Spamming Spoofing Makes the communication look as if someone else sent it so as to gain confidential information. 6-3 Copyright © 2015 Pearson Education, Inc. Forms of Spoofing E-mail spoofing Caller ID spoofing IP address spoofing Address Resolution (ARP) spoofing SMS spoofing Web-page spoofing (phishing) DNS spoofing 6-4 Copyright © 2015 Pearson Education, Inc. Why is there spoofing? Well its because the perpetrator of the fraud wants you to think that they are someone else that you’d trust. For example: E-mail spoofing, allows you to think that the e-mail you received is from someone you know. This type of attack is often combined with a social engineering technique called phishing. For example, perpetrators will send an e-mail spoofing the senders address from your bank. Inside the e-mail they will embed a link which they hope you will click on it and use your login and password basically giving them access to your bank account. Caller ID spoofing will display the wrong number on your phone hoping that you think it’s from a trusted source (e.g., Bank). IP address spoofing is used to conceal the identity of a sender of DoS attacks. ARP spoofing allows for man in the middle as well as DoS attacks. ARP spoofing can allow the perpetrator to “sniff” the data that is coming over the Internet. Sniffing means that the perpetrator can see the data as it is passing from the source to the intended destination over the Internet. SMS spoofing is falsifying the sender of a text message (it can also be used in phishing scams). 4 Hacking with Computer Code Cross-site scripting (XSS) Uses vulnerability of Web application that allows the Web site to get injected with malicious code. When a user visits the Web site, that malicious code is able to collect data from the user. Buffer overflow attack Large amount of data sent to overflow the input memory (buffer) of a program causing it to crash and replaced with attacker’s program instructions. SQL injection (insertion) attack Malicious code inserted in place of a query to get to the database information 6-5 Copyright © 2015 Pearson Education, Inc. 5 Other Types of Hacking Man in the middle (MITM) Hacker is placed in between a client (user) and a host (server) to read, modify, or steal data.
