Sport Management, Becoming a Profession or Being Professional: A Response to Dowling
Packianathan Chelladurai 글로벌지식마케팅경영학회 2018 Journal of Global Sport Management Vol.3 No.4
Based on Abbotts (1988) theory of a profession and Greenwood’s (1957) five attributes of a profession, Dowling (2018) has examined the status of sport management as an academic profession. After carefully scrutinizing the status of sport management on those attributes, Dowling rightfully concludes that sport management is a semi or quasi profession. Accepting this position, I explore further the factors that limit the field of sport management from gaining recognition from society as a profession. Given that sport management is not likely to be designated as a profession by society and be given the authority to supervise and control the activities of its members, I suggest that being professional in our operations both at the individual and organizational levels is more critical than being called a profession. I also point out that the steps and processes of being professional have been articulated in several of our publications and pronouncements.

Study Design: A retrospective radiological study of the ligamentum flavum (LF). Purpose: We determined the relationship of dorsal spinal LF thickening with age and sex using magnetic resonance imaging (MRI). We also determined whether LF thickening has a predominant tendency to occur at a specific dorsal level and on a specific side. Overview of Literature: Many researchers have studied LF thickness at dorsal levels in patients with compressive myelopathy. However, there is a dearth of literature pertaining to the study of dorsal LF thickness in patients without myelopathy. Methods: LF thickness was measured at dorsal levels from T1 to T12 on both sides using MRI in 100 individuals. The patients were divided into three groups based on age: 20 to 40, 41 to 60, and >60 years. On axial T2-weighted imaging at the mid-disc level, LF thickness was measured perpendicular to the lamina border, either at half the length of LF or at maximum thickness, whichever was greater. Results: We found that LF thickness does not increase significantly with increasing age and there was no significant disparity in LF thickness between the sides and sexes. We also found that there was a significant increase in LF thickness at the T10–T11 level (mean value, 3.27±0.94 mm). Conclusions: LF thickness does not appear to have any side/sex dominance. LF thickening has a predominant tendency to occur specifically at the T10–T11 level. This may be due to maximum tensile strength and mobility at this level. Because there is an increased tendency for LF thickening at the T10–T11 level, this may be used as a reference point for counting the vertebral levels.
Sport: A Right? A Public Good?

governments may set up specific agencies to engage in social marketing of participation in sports and physical activity. A good example of such an agency is Partcipaction in Canada whose goals are: To ensure physical activity, as key determinat of health, is a priority on the national agenda, To inspire Canadians to move more and inspire society to make it easier to do so, To develop a legacy of collaboration and partnership in the sector, To attract significant investment to the sector, and To manage and operate with the highest standards of good governance, efficiency, and professionalism. (Participaction Canada, 2014). Equally important is to facilitate such free play by providing facilities, play areas, and equipment. Existing sport facilities should be made accessible by the general population. Governments at various levels can also construct new play facilities and create open spaces for people to engage in various forms of sports. In addition, permanent equipment such as basketball boards, volleyball and badminton posts and nets, and soccer goalposts can be set up to encourage participation in those activities.

<P>3-Hydroxypropionic acid (3-HP) is a commercially valuable chemical with the potential to be a key building block for deriving many industrially important chemicals. However, its biological production has not been well documented. Our previous study demonstrated the feasibility of producing 3-HP from glycerol using the recombinant Escherichia coli SH254 expressing glycerol dehydratase (DhaB) and aldehyde dehydrogenase (AldH), and reported that an “imbalance between the two enzymes” and the “instability of the first enzyme DhaB” were the major factors limiting 3-HP production. In this study, the efficiency of the recombinant strain(s) was improved by expressing DhaB and AldH in two compatible isopropyl-thio-β-galactoside (IPTG) inducible plasmids along with glycerol dehydratase reactivase (GDR). The expression levels of the two proteins were measured. It was found that the changes in protein expression were associated with their enzymatic activity and balance. While cloning an alternate aldehyde dehydrogenase (ALDH), α-ketoglutaric semialdehyde dehydrogenase (KGSADH), instead of AldH, the recombinant E. coli SH-BGK1 showed the highest level of 3-HP production (2.8 g/L) under shake-flask conditions. When an aerobic fed-batch process was carried out under bioreactor conditions at pH 7.0, the recombinant SH-BGK1 produced 38.7 g 3-HP/L with an average yield of 35%. This article reports the highest level of 3-HP production from glycerol thus far. Biotechnol. Bioeng. 2009; 104: 729–739 © 2009 Wiley Periodicals, Inc.</P>
