The real issue of the War was slavery, which the North sought to expunge from the face of the earth. The Northern version is that the so-called Lost Cause is a myth in the sense that it is based not on historical fact but rather on wishful, sentimental, and self-justifying thinking developed after the fact of a bitter defeat. Finally, only a minority of Southerners owned slaves. It was New England ships after all that brought slaves to American shores. Slavery was an institution of long-standing for the presence of which both North and South had responsibility. ![]() Some refer to this as states’ rights, the self-governance of the states in their relation to the central government. The main issue at stake was regional self-determination, mostly political and economic. Put briefly, the Southern version holds that while the South was defeated in the War Between the States, the cause for which it fought was noble and some would even say sacred. The other version originated north of the old surveyor’s line a bit later. One of these originated in the original states of the Southern Confederacy. Now, to clarify and to anticipate the rest of this essay, I have to say that there are two versions of the Lost Cause. Which brings us to my theme today: John Pelham and the “myth” of the Lost Cause. ![]() I gather that it is the very sort of book I had aimed to write. Maxwell (University of Alabama Press, 2011). Recently, however, I came across a notice of a book on the Alabama artillerist entitled The Perfect Lion, by Jerry H. I finally abandoned it as a lost cause of my own. The business of earning a living and other distractions, however, intervened to keep that project from being completed. ![]() Some twenty years ago I had planned to write a full-length study of John Pelham-known in the South as the Gallant John Pelham-and the making of myth. ![]() Unfortunately, these new regulations have not stated a level for reliability of the visual fields performed. According to the rules of the Swedish Transport Agency is the ophthalmologist who decides whether to use the binocular or the monocular test in testing driving capacity. The new rules outlined clear for not only which visual field testing method was to be used, but also how the results should be interpreted and assessed, and guidelines for doctors to report drivers not fulfilling the requirements. Disadvantages of this technique are that it is not possible to judge whether the defect is absolute or relative, and there is no way to control fixation stability since the binocular testing conditions eliminate naturally occurring blind spots which are used for fixation control in other tests.īeginning September 1, 2010, new regulations for medical requirements for drivers’ licenses in Sweden went into effect. During binocular viewing, each location in the right monocular field has a corresponding point in the left monocular field and vice versa. An advantage of this method is that it allows for naturally-occurring binocular enhancement, in which two seeing eyes compensate for defects in the fellow eyes. This binocular method is useful in glaucoma patients with later stage bilateral visual field defects, and is used to assess the remaining visual ability or disability. The test consists of 120 white test points shown with equal, non-adjustable suprathreshold light intensity of 10 dB and examines more than 130° of the field. Esterman visual field perimetry is a binocular testing method which is also available on the HFA. The HFA offers several different testing programs, each with specialized testing strategies, including threshold programs which are appropriate for drivers’ license testing. The Humphrey Field Analyzer (HFA) is an automated, static threshold perimeter, using stimuli of varying luminance in order to find the minimum luminance which can be detected in each test point. Until now, there has not been a specific testing method required by the Swedish Transport Agency, and the requirement that was specified was stated simply that the applicant’s binocular visual field must be at least equivalent to a normal visual field of one eye. Studies have shown that drivers with limited fields of vision have significantly poorer driving capabilities with regard to speed adjustment with lane changes, maintaining lane positions in a curve, as well as anticipatory skills. The visual field is of great importance while driving a limited field of vision hinders the driver’s capability of not only detecting objects in the periphery, but also judging distances and speed. Glaucoma causes damage to the optic disc, which leads to visual field defects. Glaucoma is defined as ”a disease causing damage to the optic nerve with resulting visual field defects, characterized by slow progression”. ![]() ![]() There is a long list of eye diseases and conditions affecting the field of vision, among them glaucoma. ![]() The binocular visual field test (HEVF) seems not be as efficient as the HVF in finding visual field defects in glaucoma subjects, and is therefore doubtful in evaluating visual capabilities in traffic situations. The monocular visual field test (HVF) gave more specific information about the location and depth of the defects, and therefore is the overwhelming method of choice for use in diagnostics. There were no subjects who passed the HVF, but failed the HEVF. There was a significant difference between HEVF and HVF (χ 2, p = 0.004). Eight subjects passed the HEFV but failed the HVF. Sixteen subjects passed both tests, and sixteen subjects failed both tests. Resultsįorty subjects were recruited and participated in the study. Assessment of results was constituted as either “pass” or “fail”, according to the new medical requirements put into effect Septemby the Swedish Transport Agency. HVF SITA Fast 24–2 full threshold (monocularly) and HEVF (binocularly) were performed consecutively on the same day on 40 subjects with glaucomatous damage of varying degrees in both eyes. The purpose of this study was to compare the monocular Humphrey Visual Field (HVF) with the binocular Humphrey Esterman Visual Field (HEVF) for determining whether subjects suffering from glaucoma fulfilled the new medical requirements for possession of a Swedish driver’s license. What is right about my observation & what is the best way forward? The specific OS I installed for unrelated reasons & because it is probably not supported by VB was quite troublesome to install & get working, so I do not want to mess this up. When I start the VM, though, I get an alert there is VirtualBox 5.0.10 update, but not sure whether to upgrade, because I have no idea what that means, based on the above stated problem. I decided to remove it & used 5.0.8 instead. Visit the site, and navigate to Windows 7 ISO.

Instead use samba shares - fast and efficient.I have always used 64-bit versions of Guest VMs, but because of a re-installation of Windows 10 (after originally updating from Win 8.1), I had to re-install VB as well & took the latest version VirtualBox 5.0.10 for Windows hosts x86/amd64.Īs I went on to install some OS, I wanted to use the 64-bit version since my laptop also uses Win 10 64bit & I had used a 64-bit of this guest OS before. Do not use the shared folders feature in virtualbox, it's quite buggy especially with windows 7 (and 64 bit). That's it, now you have 2 way communication, with apache/any other service available as well as internet.

Karena panjang kode instruksi relatif pendek, hanya sedikit saja dari RAM yang digunakan untuk menyimpan instruksi-instruksi tersebut. Satu kelebihan dari sistem ini adalah kompailer hanya menerjemahkan instruksi-instruksi bahasa tingkat-tinggi ke dalam sebuah bahasa mesin. Bekerja secara langsung melalui memori komputer dan tidak memerlukan instruksi lain seperti fungsi baca maupun menyimpan. MULT dalam hal ini lebih dikenal sebagai “complex instruction”, atau instruksi yang kompleks. Saat dijalankan, instruksi akan membaca dua nilai dan menyimpannya ke 2 register yag berbeda, melakukan perkalian operan di unit eksekusi dan kemudian mengambalikan lagi hasilnya ke register yang benar. Untuk tujuan contoh kita kali ini, sebuah prosesor CISC sudah dilengkapi dengan sebuah instruksi khusus, yang kita beri nama MULT. Hal ini bisa tercapai dengan cara membuat perangkat keras prosesor mampu memahami dan menjalankan beberapa rangkaian operasi. Tujuan utama dari arsitektur CISC adalah melaksanakan suatu perintah cukup dengan beberapa baris bahasa mesin sedikit mungkin. Misalnya, kita akan melakukan perkalian ( product) dua angka, satu disimpan di lokasi 2:3 sedangkan lainnya di lokasi 5:2, kemudian hasil perkalian tersebut dikembalikan lagi ke lokasi 2:3. ![]() Namun, unit eksekusi hanya beroperasi untuk data-data yang sudah disimpan ke dalam salah satu dari 6 register (A, B, C, D, E atau F).
