Executive coach certification and selection: a contrarian's viewpoint
Authors: McCleary David 
Published: July 2006

PurposeThis paper is written to increase awareness and focus on the choice of executive coaches. There is a growing trend of selecting coaches based solely on a certification. This methodology of coach selection could lead to disappointing and lackluster results.Design/methodology/approachThis scope of the paper is executive coaching within organizations, with a specific focus on the potential prerequisite of a coaching certification. The paper is written from the author's point of view. The author has interacted with and interviewed numerous coaches and leaders and extensive personal experience on the subject.FindingsThe results are that quality coaching is primarily about whom the coach is, not what techniques or certifications they hold. The “self” of the coach is the instrument of change, not a bag of tricks accumulated during a “coaching college”.Practical implicationsCoaching certification for many is a defense against personal accountability and responsibility: the responsibility to select and hire quality coaches and the responsibility to be a quality coach. Orchestrating quality coaching programs is difficult and laborious work that cannot be minimized or made more efficient. By certifying coaches we could be sterilizing otherwise potentially powerful relationships and denuding overall quality learning experiences (let alone creativity and further learning) on a grand scale. Any attempt to make the choice of a coach more efficient will potentially reduce the quality of the future coaching experience. Perhaps coaching leaders to coach is a more valuable and meaningful intervention then merely coaching one person's performance.Originality/valueQuality coaching experiences consistently and significantly increase performance for many leaders. This paper is intended to help leaders and those that assist them in coach selection and coaching program orchestration increase the value and return on investment of coaching interventions.

Do investors herd intraday in Australian equities?
Authors: Henker Julia , Henker Thomas , Mitsios Anna 
Published: July 2006

PurposeThe purpose of this research is to consider whether market wide herding occurs intraday.Design/methodology/approachUsing the 1995 Christie and Huang and the 2000 Chang et al. models, the paper tests whether market wide and industry sector herding occurs intraday in the Australian equities market.FindingsNeither market wide nor industry sector herding occurs intraday.Research limitations/implicationsBoth herding measures focus on one specific type of herding, herding evidenced by changes in the cross‐sectional return distribution. Therefore the herding measures are ill suited to capture the effects of period specific abnormally high or low market returns and they can also capture herding of market participants or groups of market participants only in as far as it manifests itself in security specific returns.Originality/valueNo previous studies have considered the possibility of intraday herding in equities markets. Even if there is little evidence of herding over longer time periods, market frictions and inefficiencies continue to be exploited at least anecdotally by traders with very short time horizons to the detriment of longer term investors.
Auditor choice, retained ownership, and earnings disclosure for IPO firms
Authors: Wang Kun , Iqbal Zahid 
Published: July 2006

PurposeThe purpose of this research is to provide further evidence on the association between the IPO signaling mechanisms (i.e. retained ownership, auditor choice, and earnings forecast) by using a less restrictive sample and by performing additional empirical tests.Design/methodology/approachSingle equations are used as the baseline approach to estimate the three models. In addition, Copley and Douthett's 2002 simultaneous equation systems are applied to examine whether the results remain the same. Moreover, ranked values of the risk proxies of IPOs are derived and general least squares are run on these ranked variables.FindingsFindings indicate that auditor reputation and retained ownership are not substitute signals. It is observed that as firm risk increases, entrepreneurs are more likely to retain higher ownership to signal firm value. In addition, contended that positive earnings disclosure before IPO is not associated with retained ownership in a significant manner. An analysis of the economic implication of the results suggests that findings are more representative.Research limitations/implicationsIn this study the risk measures used (as well as those used in other studies) may not adequately proxy for offering firm risk. Additionally, the sample is restricted by missing values of the retained ownership variable. Further study can expand the sample using retained ownership obtained from other data sources. A study employing alternative approaches to control for the supply‐side effect of firm risk could be also productive.Practical implicationsFindings are of particular interest to firms that are planning to go to the public. They need to evaluate the benefit and cost of selecting a particular information system in signaling firm value to the market.Originality/valueUsing a larger sample, comprehensive testing periods, and ranked risk proxies contribute to the literature on evaluating singling mechanisms of IPOs.
Inflation and bond‐stock characteristics of international security returns
Authors: Kim Moon K. , Shukla Ravi 
Published: July 2006

PurposeThe purpose of this research is to explain the cross‐sectional variation in the relation between international security returns and expected inflation based on their sensitivities to world stock and bond factors.Design/methodology/approachThe paper shows regress inflation sensitivities of returns on country indexes and international mutual funds on their sensitivities to world stock and bond indexes.FindingsThis paper shows the inflation sensitivity of a security is positively (negatively) related to its sensitivity to the world bond index (world stock index).Research limitations/implicationsThe paper shows that while the model is applicable to individual securities as well as portfolios, it is tested using portfolios only.Originality/valueThe paper shows the results allow one to assess the inflation sensitivity of a security using its sensitivity to the bond and the stock market. The more bond‐like a security is, the higher its sensitivity to inflation.
Dynamic loading systems for ground testing of high speed aerospace actuators
Authors: Mare Jean‐Charles 
Published: July 2006

PurposeTo develop structured guidelines for the synthesis of dynamic force simulators that are required for the testing of high speed aerospace actuators. To provide realistic and proven solutions at both test bench hardware and control design levels.Design/methodology/approachThe state of the art in control design applied to load simulators in mainly based on complex controllers and does not take into account practical considerations. The objective of the present work is to provide generic preliminary design rules to ensure that the test bench architectures (frame, power transmission and control) and the components specifications are consistent with the targeted performance. Once selected the appropriate power transmission architecture, a linear approach is used as a foundation to generate design rules. Then, preliminary design is achieved thanks to the introduction, as early as possible, of the unavoidable technological defects.FindingsA step‐by‐step methodology allows the designer to select the controller architecture and to specify components with special care to their consistency with the required dynamic performance. The linear then practical approach generates key rules that can be used in the very early phase of the test bench design.Originality/valuePractical considerations on the components static and dynamic limitations are introduced progressively to make the natural test bench performance as consistent as possible with the performance requirements. Consequently, the controller becomes simpler to design and robust.

Authors: Zhao Jie , Yu Shuchun , Cai Hegao 
Published: July 2006

PurposeIn order to solve the problem that dynamic programming (DP) stereo algorithm is slow, a local‐global stereo matching algorithm is presented. In this method, local and global stereo algorithms are united to apply to the stereo vision field.Design/methodology/approachLocal and DP stereo algorithms are used. Multi‐resolution images are obtained by pyramid algorithm and matching costs are gained by using eight‐stripe correlation window.FindingsThe time of disparity space image creation is greatly reduced because matching costs are computed by eight‐stripe window. Candidate ground control points (GCPs) are gained in the low‐resolution image. The total time of gaining GCPs is decreased in the extreme. Whole algorithm has a high matching‐rate and a fast speed.Research limitations/implicationsThe time of the whole algorithm is still a little bigger than local algorithm.Practical implicationsThe findings can be used in the stereo vision system equipped with planet vehicle.Originality/valueLocal and global stereo algorithms are united to apply to the stereo vision field. Matching costs are gained by using eight‐stripe correlation window.
Control of suddenly expanded flow
Authors: Khan S.A. , Rathakrishnan E. 
Published: July 2006

PurposeThis paper presents an experimental investigation to study the effectiveness of micro jets under the influence of Over, Under, and Correct expansion to control the base pressure in suddenly expanded axi‐symmetric ducts.Design/methodology/approachFour micro jets of 1 mm orifice diameter located at 90° intervals along a pitch circle diameter of 1.3 times the nozzle exit diameter in the base region was employed as active controls. The tests were conducted for Mach numbers 1.5, 1.3, 1.6, 1.8, 2.0, 2.5, and 3.0. The jets were expanded suddenly into an axi‐symmetric tube with cross‐sectional area 2.56 times that of nozzle exit area. The L/D ratio of the sudden expansion tube was varied from 10 to 1.FindingsFrom the present studies, it was found that the maximum increase in base pressure is 152 percent for Mach number 2.58. It is found that the micro jets do not adversely influence the wall pressure distribution.Research limitations/implicationsAs a result of developments in space flights and missile technology, the base flows at high Reynolds numbers continues to be an important area of research. Our understanding of many features of base flows remains poor, due to inadequate knowledge of turbulence, particularly in the presence of strong pressure gradient.Originality/valueThe paper shows that micro jets can serve as an effective controller raising the base suction to almost zero level for some combination for parameters. The nozzle pressure ratio has a definite role to play in fixing the base pressure with and without control. There is no adverse effect of the micro jets on the flow field in the duct.

Women who fall by the roadside: gender, sexual risk and alcohol in rural Uganda
Authors: Wolff Brent , Busza Joanna , Bufumbo Leonard , Whitworth Jimmy 
Published: July 2006

ABSTRACTAims To investigate community perceptions about the different relationship between alcohol consumption and sexual risk‐taking for men and women in a high HIV prevalence African setting.Design and setting Participatory learning and action (PLA) activities were conducted in five rural villages in south‐western Uganda in 2002. For each village, discussions and visualization activities over the course of 5 days explored local concepts of fun, drinking alcohol and HIV‐related behavioural risks. Twelve focus group discussions (FGDs) investigated emerging themes. Analysis is based on visual outputs, observation notes and focus group transcripts.Participants Attendance at sex‐segregated PLA sessions was open to all village residents. FGDs were purposively sampled from drinkers and general population groups.Findings For men, drinking is conducted invariably outside the home, usually at night in bars, emphasizing independence, masculinity and freedom from domestic responsibilities. For women, drinking outside male supervision challenges feminine ideals of domesticity and signifies potential sexual vulnerability. Accepting drinks from men was viewed as signifying assent to sex and refusal could justify men resorting to sexual coercion. Even though drinking is seen to promote sexual risk, HIV prevention campaigns were considered unwelcome in bars. Communities preferred seminars involving drinkers and non‐drinkers alike.Conclusions Public drinking in this community serves as a marker for men willing to exercise privileges of independence (sexual and otherwise) and women willing to defy gender norms (and risk the sexual consequences). The social and symbolic context of drinking suggests why effective HIV prevention around alcohol should not be limited to drinking environments alone.
Group size and composition are correlated with population density in the group‐territorial blue korhaan (Eupodotis caerulescens)
Authors: Moreira Francisco 
Published: July 2006

AbstractThe blue korhaan (Eupodotis caerulescens) is a poorly known bird endemic to the grasslands of southern Africa. It lives in permanently held territories defended by groups of individuals. During 2001 and 2002, 61 transects were carried out along 544 km of roads in Mpumalanga province (South Africa) to collect data on territory density and group size and composition in this species. Habitat, altitude and topography variables were measured to evaluate their influence on population density. Average territory density was 1.56 ± 0.19 (SE) territories per 5 km and maximum densities attained 5.6 territories per 5 km. Within its area of occurrence, higher densities occurred along transects with larger proportion of short grassland (either burned or grazed) and flatter topography. Mean group size was 3.03 ± 0.11 birds (n = 119), with 87.4% of the groups having one to four birds. Most common group composition was one male and one female‐like (34.5%), followed by two male and one female‐like (17.2%) and two male and two female‐like (13.8%). Single individuals were always males, and the male/female‐like ratio peaked at a group size of three and decreased thereafter. Mean group size increased with territory density (rs = 0.42, P = 0.007, n = 41). There were no differences in group size across habitat types. The occurrence of habitat saturation and cooperative breeding in this species could explain the observed results.
