Development of an injection therapy module.
The title of my project is 'the Development of an Injection therapy Module'. I undertook this project because I had been charged to develop an injection therapy module for the Society of Orthopaedic Medicine (SOM) (see below), as part of a postgraduate pathway towards an MSc in Orthopaedic Medicine at Middlesex University (MU). The
project has three clear parts that link to form the cohérent project as shown in the table below. This 'wrap around' reflective commentary forms the final component to
demónstrate the cohésion both within the project itself and its place in my doctoral programme. Within this commentary the term 'project' is reserved for the whole project only
Defeating the Ben-Zvi, Blackburn, and Tsaban Attack on the Algebraic Eraser
The Algebraic Eraser Diffie-Hellman (AEDH) protocol was introduced in 2005
and published in 2006 by Anshel-Anshel-Goldfeld-Lemieux as a protocol suitable
for use on platforms with constrained computational resources, such as FPGAs,
ASICs, and wireless sensors. It is a group-theoretic cryptographic protocol
that allows two users to construct a shared secret via a Diffie-Hellman-type
scheme over an insecure channel.
Building on the refuted 2012 permutation-based attack of
Kalka-Teichner-Tsaban, in 2015 Ben-Zvi-Blackburn-Tsaban (BBT) presented a
heuristic attack that attempts to recover the AEDH shared secret. In their
paper BBT reference the AEDH protocol as presented to ISO for certification
(ISO 29167-20) by SecureRF. The ISO draft contains two profiles using the
Algebraic Eraser. One profile is unaffected by this attack; the second profile
is subject to their attack provided the attack runs in real time. This is not
the case in most practical deployments.
The BBT attack is simply a targeted attack that does not attempt to break the
method, system parameters, or recover any private keys. Rather, its limited
focus is to recover the shared secret in a single transaction. In addition, the
BBT attack is based on several conjectures that are assumed to hold when
parameters are chosen according to standard distributions, which can be
mitigated, if not avoided. This paper shows how to choose special distributions
so that these conjectures do not hold making the BBT attack ineffective for
braid groups with sufficiently many strands. Further, the BBT attack assumes
that certain data is available to an attacker, but there are realistic
deployment scenarios where this is not the case, making the attack fail
completely. In summary, the BBT attack is flawed (with respect to the SecureRF
ISO draft) and, at a minimum, over-reaches as to its applicability

Stability of Extemporaneously Prepared Sodium Benzoate Oral Suspension
The stability of extemporaneously prepared sodium benzoate oral suspension in cherry syrup and Ora-Sweet was studied. Oral solutions of 250-mg/mL sodium benzoate were prepared in either cherry syrup or Ora-Sweet. To a beaker, 50 grams of Sodium Benzoate Powder USP was dissolved and filtered, the solution was divided equally into two parts, and each aliquot was added into two separate calibrated 100-mL amber vials. In the first vial, cherry syrup was added to make a final volume of 100 mL. In the second vial, Ora-Sweet was added to give a final volume of 100 mL. This process was repeated to prepare three solutions of each kind and all were stored at room temperature. A 250-µL sample was withdrawn immediately after preparation and again at 7, 14, 28, 60, and 90 days for each sample. At each time point, further dilution was made to an expected concentration of 0.25 mg/mL with sample diluent, and the samples were assayed in triplicate by stability-indicating high-performance liquid chromatography. Stability was defined as the retention of at least 90% of the initial concentration. At least 92% of the initial concentration of sodium benzoate in cherry syrup and at least 96% of the sodium benzoate in Ora-Sweet remained throughout the 90-day study period. There were no detectable changes in color and no visible microbial growth in any sample. Extemporaneously compounded suspensions of sodium benzoate in cherry syrup or Ora-Sweet were stable for at least 90 days when stored in a 4-oz amber plastic bottle at room temperature in reduced lighting
From the Big Five to the Big Four? Exploring Extinction Accounting for the Rhinoceros
Purpose
The purpose of this paper is to explore a possible framework for extinction accounting which builds on but also extends significantly the existing GRI guidelines relating to species identified by the International Union for the Conservation of Nature Red List as under threat of extinction.
Design/methodology/approach
The paper analyses disclosures relating to rhinoceros conservation and protection produced by top South African-listed companies in order to assess the current state of “extinction accounting”. Following this analysis, the authors explore and discuss a potential framework for extinction accounting which may be used by companies to demonstrate their accountability for species and disclose the ways in which they are working alone, and in partnerships, to prevent species extinction.
Findings
Corporate disclosures relating to rhinoceros may be interpreted as emancipatory. The authors identify several disclosure themes dealing with rhinoceros in integrated and sustainability reports of large South African companies and on their websites. Contrary to initial expectations, there is evidence to suggest corporate awareness of the importance of addressing the risk of this species becoming extinct.
Research limitations/implications
The authors have relied on public corporate disclosures and would like to extend the work further to include interview data for a further paper.
Practical implications
An extinction accounting framework may be applied to corporate accounting and accountability for any species under threat of extinction. The framework may also be considered for use as a tool for institutional investors as well as NGO engagement and dialogue with stakeholder companies.
Social implications
The rhinoceros has, from the analysis, significant cultural, heritage, eco-tourism and intrinsic value. Developing and implementing an emancipatory extinction accounting framework to prevent extinction will have a substantial social and environmental impact.
Originality/value
This is the first attempt to the knowledge to explore accounting for extinction and a possible extinction accounting framework. It is also the first attempt to investigate accounting and accountability for the rhinoceros
Jazz by the Sea: KRML and the Radio Presence of ‘America’s Classical Music’
The last for-profit radio station with an all-jazz format was located not in a major city or center of jazz activity, but in Carmel, California. KRML-AM 1410 broadcasted jazz almost exclusively for three decades, before changing to an eclectic rock format in October 2012. This article attempts to explain the conditions that enabled this small but affluent community to sustain a presence for jazz on the airwaves for so long. Moreover, it takes a microhistorical approach that examines the ways that KRML’s history reflects the broader national trends in jazz programming. As jazz has accrued “cultural nobility,” a fancy for the music has become a social indicator of one’s level of cultural sophistication. Canonized as a quintessentially American expressive form and repackaged as a non-intrusive, unthreatening vehicle for tranquil repose and nostalgia, jazz thus complements the aura of refinement and serenity that Carmel residents have sought to create and have fought to maintain for over a century. Its jazz programming informed by such discursive shifts, KRML sought to sway listeners to accept jazz as the ideal accompaniment to the placid, laid-back Carmel lifestyle
Sacred Swing: The Sacralization of Jazz in the American Bahá'í Community
Much modern jazz performance is imbued with religious significance or “sacred intentionality”, as revealed in the Bahá’í conceptions of jazz as a vehicle for worship and spiritual transcendence. Although earlier generations of believers objected to jazz because of its presumed moral and aesthetic poverty, jazz has become a staple in Bahá’í public culture and proclamation activities, partially due to the influence of prominent jazz musicians who became Bahá’ís, such as Dizzy Gillespie, James Moody, Flora Purim, and Tierney Sutton. Oral history and textual research are used to explore the dialectic between jazz and Bahá’í spiritual teachings and practices, the impact of the Faith’s theological and social doctrines on the creation of jazz music by its adherents, and conversely the effects of jazz on worship activities and religious identity in the American Bahá’í community. Musicians detect synergy between improvisation and spiritual searching, group interaction and selfless consultation, and jazz’s multicultural roots and Bahá’í emphasis on unity-in-diversity. The ambiguous aesthetic stature of jazz challenged individual believers and Bahá’í institutions to reconsider and expand their notions of what types of music are suitable for reverent worship, thus contributing to the maturation of this spiritual community’s inclusive ethos
