We intend this book to act as a guide writ large for would-be champions of OER, that anyone—called to action by the example set by our chapter authors—might serve as guides themselves. The following chapters tap into the deep experience of practitioners who represent a meaningful cross section of higher education institutions in North America. It is our hope that the examples and discussions presented by our authors will facilitate connections among practitioners, foster the development of best practices for OER adoption and creation, and more importantly, lay a foundation for novel, educational excellence.

The Caribbean Examinations Council (CXC) Caribbean Secondary Education Curriculum (CSEC) mathematics syllabus has been used to guide the selection and sequencing of quality Open Education Resources (OER) to create a free textbook or online course. The resources have been collected and vetted by experienced mathematics teachers and organised to allow a 'reader' gain mastery of each of the CSEC topics and objectives. The topics available for study include:

Computation
Number Theory
Consumer Arithmetic

Developing a course, and associated materials, to support professional development can often be a costly enterprise. Designers and developers need to consider curriculum design, materials development, quality assurance, platform customisation and evaluation. Following this process step by step is often protracted and costly. The ADDIE model of instructional design, a popular and often cited ideal approach to creating courseware, suggests that analysis of needs, courseware design and development, implementation and course evaluation is required by any entity bent on creating effective courses.

In contrast to this mindset, however, there is evidence that a collaborative-shared approach to instructional design challenges the ADDIE model’s assumption that each step needs to be done in-house. Since 2011, several Teacher ICT Integration professional development initiatives around the globe have demonstrated that burdens in both design and development phases can be shared, shortening the time required to design courses and develop the accompanying resources. This approach also is more cost effective than typical ventures.

An examination of two contrasting rifted margins: the Red Sea and Gulf of California, leading to identification of similarities and differences associated with rifting and lithospheric rupture in each setting.

This extract from Ovid's 'Theban History' recounts the confrontation of Pentheus, king of Thebes, with his divine cousin, Bacchus, the god of wine. Notwithstanding the warnings of the seer Tiresias and the cautionary tale of a character Acoetes (perhaps Bacchus in disguise), who tells of how the god once transformed a group of blasphemous sailors into dolphins, Pentheus refuses to acknowledge the divinity of Bacchus or allow his worship at Thebes. Enraged, yet curious to witness the orgiastic rites of the nascent cult, Pentheus conceals himself in a grove on Mt. Cithaeron near the locus of the ceremonies. But in the course of the rites he is spotted by the female participants who rush upon him in a delusional frenzy, his mother and sisters in the vanguard, and tear him limb from limb.
The episode abounds in themes of abiding interest, not least the clash between the authoritarian personality of Pentheus, who embodies 'law and order', masculine prowess, and the martial ethos of his city, and Bacchus, a somewhat effeminate god of orgiastic excess, who revels in the delusional and the deceptive, the transgression of boundaries, and the blurring of gender distinctions.
This course book offers a wide-ranging introduction, the original Latin text, study aids with vocabulary, and an extensive commentary. Designed to stretch and stimulate readers, Gildenhard and Zissos's incisive commentary will be of particular interest to students of Latin at AS and undergraduate level. It extends beyond detailed linguistic analysis to encourage critical engagement with Ovid's poetry and discussion of the most recent scholarly thought.

A 34 year-old otherwise healthy man presented with new onset headaches, mild confusion, and subtle left-sided weakness. An MRI scan showed a large heterogeneous 8.9cm x 6.0cm right fronto-temporo-parietal mass with nodular enhancement, significant surrounding edema, and 15mm of midline shift. He underwent an urgent right craniotomy, and began appropriate therapy. Unfortunately, within one week of completion of this therapeutic regimen, his symptoms worsened. He was found to have multiple new bilateral dural-based nodular enhancing lesions on repeat brain MRI. No spinal abnormalities were found. He underwent resection of one of the new lesions. The patient was initiated on a new treatment plan, but unfortunately, neuroimaging revealed further progression of disease (Figure 1). He passed away 5 months and 1 day after diagnosis.

The patient was a 37-year-old African American woman with a history of poorly treated HIV infection, diagnosed in 2001, with progression to AIDS. A recent CD4 count showed 7 cells / cubic millimeter with a viral load of 745,000 copies / milliliter. She presented to the emergency department with fever up to 102.3 degrees Fahrenheit and a cough productive of yellow sputum with no hemoptysis. She denied any recent weight loss. She denied ever having a positive PPD, but could not remember when she was last tested. She had been admitted 6 months previously for similar symptoms, and all cultures were negative except for the stool, which was positive for non-tuberculous mycobacteria.

A 45-year-old woman presented to our institution with progressive upper and lower extremity proximal weakness of a few weeks' duration. 3 months prior, the patient received a diagnosis of systemic lupus erythematosus and started on hydroxychloroquine; she had been treated with low dose prednisone for her weakness for the last 3 weeks. Physical examination showed severe proximal weakness, grade 2/5, in the bilateral upper and lower extremities with retained strength in all other muscle groups. The patient had an erythematous rash on her face, chest, and upper back. There was no clinical evidence of involvement of other organs.

This 4-year-old girl presented to the emergency department complaining of fever and pain in the lower extremities with refusal to bear weight. On four occasions a hip x-ray was performed, and she was sent home with pain medications. No laboratory studies were performed. She presented again with the above symptoms and weight loss (weight 13.8 kg, <10th percentile for age.) She was admitted and worked up for possible malignancy. Laboratory studies including a bone marrow biopsy were performed.

A 65-year-old man was diagnosed with esophageal adenocarcinoma with metastases to liver and lungs in July of 2001. Due to metastatic disease, he was not deemed to be a candidate for surgical resection but was given radiation and chemotherapy. Seven months later he presented with an 8x5x3.5 cm frontal, transcalvarial metastatic lesion. Past medical history includes cholecystectomy, appendectomy, osteoarthritis, left hemipelvectomy following a motor vehicle accident in 1970, and smoking with intermittent alcohol abuse since the age of 15. His clinical course continued to deteriorate and he eventually expired in December of 2002. An autopsy revealed widespread metastatic adenocarcinoma to the lungs, liver and calvarium with superficial extension into the dorsal surface of the frontal lobes, bilaterally. An acute, severe bronchopneumonia was also found.

A 73 year-old male presented with a 6 month history of progressive tetraparesis, during which he had deteriorated markedly from being mobile and performing in a steel band to completely bed-bound. Medical history included ischemic heart disease and type II diabetes mellitus. Neurological examination revealed symmetrical pyramidal weakness, pathologically increased deep tendon reflexes and increased tone in all 4 limbs. Plantar response was upgoing bilaterally. Pinprick-sensation was reduced below the neck. Cranial nerve examination was normal. An MRI scan showed a well-demarcated extra-axial mass on the dorsal surface of the lower medulla/upper cervical cord extending from the level of the clivus to the body of the axis inferiorly (figures 1, 2, 3 and 4). The mass exhibited heterogeneous hyper-intensity on T2W (figure 1), low-to-intermediate signal on T1W (figure 2), and florid enhancement with Gadolinium contrast-agent (figures 3 and 4). The spinal cord exhibited high T2-signal, consistent with edema, from the level of the tumour superiorly to the body of C5 inferiorly. There was no bony erosion or sclerosis, or enhancing dural 'tail'.

The patient was a 74-year-old woman with no family history of breast cancer who presented for a screening mammogram. An asymmetric density was seen in the right breast, and she was recalled for diagnostic mammogram and ultrasound 2 weeks later. The mammogram confirmed the presence of an ill-defined density in the posterior right upper outer quadrant, with some evidence of spiculation. No suspicious calcifications were seen. Ultrasound showed 2 immediately adjacent, ill-defined, hypoechoic masses in the right upper outer quadrant, 8 x 11 mm and 5 x 4 mm, with irregular margins. No axillary lymphadenopathy was noted (Fig. 1).
