Abstract
We hypothesize that a CEO’s responsiveness to security analysts’ demands for information about the firm is influenced by the structure of the CEO’s compensation package. Our analysis is based on a sample of 469 CEO presentations to security analyst societies by 149 firms during the period 1984‐1988. Consistent with the argu ments of Nagar (1999; 1998) that CEO shareholdings and golden parachutes reduce the cost to the CEO of disclosing proprietary information, we find that CEO share holdings and the presence of golden parachutes are positively associated with the total amount of information that a CEO discloses at an analyst society presentation. Consistent with the argument that CEOs whose cash compensation is sensitive to firm performance have incentives to release bad news so as to lower expectations about future performance and, hence, bonus targets, CEO cash compensation performance sensitivities are positively associated with the CEO’s willingness to disclose bad news.

Abstract
Purpose
Empire style fashion, Greek-Roman style robe with bare shoulder and chest and short sleeved with long gloves which created a slim silhouette, was worn even in winter season in Europe, where average temperature is 0-5°C. Most women suffered with catching cold and thousands caught flu and tuberculosis of the lungs, called muslin disease. The purpose of this paper is to find out clothing insulation of the robe by measuring the thermal resistance and to guess how cold they felt in this robe in winter time.
Design/methodology/approach
The authors performed the investigation on original robe shape with based on historical evidence and data, such as drawings, sketches, pattern books and sewing books, and reproduced a representative robe costume and tested its thermal insulation. The fabrics of robe were thin wool, silk and cotton following the literature evidence and preserved costume. Thermal insulation of the robes was measured using thermal manikin with the test method ISO 15831. The authors analyzed the thermal insulation of reconstructed robes with an inner cotton breech as for daily use and tested them wrapped with cashmere shawl on manikin shoulder as for severe cold weather.
Findings
The dress robes had the range of 0.61-0.67 clo regardless of the type of fabric materials, and 0.80-0.81 clo with the cashmere shawl. These values were not enough for women to keep body temperature or comfort in winter time.
Originality/value
This study combined fashion historic theory for costume reproduction with clothing science and technology for thermal insulation. Combination of costume history, construction technology and measurement engineering is the ingenious idea, and the combination of historical and scientific research evidences interdisciplinary originality.

Abstract
Cyclic voltametry and potentiodynamic single sweep techniques are used to study the electrochemical behaviour of lead in Na2CO3 solutions containing various concentrations of ClO4‐ as aggressive anion. The effects of different concentrations, in terms of destruction of passivity and initiation of pitting corrosion, were monitored with reference to the change in integrated anodic charge. It was found that Δqa (taken as a measure of the extent of pitting) varies linearly with log CClO4‐. The pitting corrosion potential, Epitting, varies with log CClO4‐ according to sigmoidal curves. These curves are explained on the basis of formation of passive, active and continuously propagating pits. Additions of aliphatic amines shift the pitting corrosion potential, Epitting, into the noble (positive) direction, indicating the inhibition action of the added amines on the pitting attack. Epitting varies with the logarithm of the inhibitor concentration according to: Epitting = a + b log Cinh. The inhibition of pitting corrosion by the aliphatic amines is assumed to be due to either competitive adsorption between the CO32– with ClO4‐ anions, and/or the chemisorption of the amine on the metal with the formation of a metal‐nitrogen coordination bond. The efficiency of these compounds as pitting corrosion inhibitors increases with the increase in the chain length of the alkyl group.

Abstract
Purpose
This study examined the wear comfort and thermal insulation properties of Al2O3/graphite particle-imbedded sheath/core and dispersed fabrics via a thermal manikin experiment.
Design/methodology/approach
Al2O3/graphite sheath/core and dispersed polyethylene terephthalate (PET) yarn (POY 120d/24f) were spun using a pilot melt bi-component conjugated spinning machine, which was texturized as 75d/24f on the belt-type texturing machine. The woven fabric specimens were made using nylon 70d/34f in the warp with three types of weft yarn: Al2O3/graphite sheath/core, dispersed and regular PET yarns. Thermal insulation properties were measured and compared in terms of the heat retention rate (I) by KES-F7 apparatus and the maximum surface temperature by light heat emission equipment, as verified by the emissivity of various fabric specimens by far-infrared ray experiment. In addition, this study examined the thermal insulation (Clo value) characteristics of the clothes made of Al2O3/graphite sheath/core and dispersed fabrics using a thermal manikin apparatus, which were compared with the properties of regular PET clothing.
Findings
The thermal insulation of the dispersed fabric was superior to that of the sheath/core fabric, which was tentatively attributed to the higher emissivity of the dispersed yarn with Al2O3/graphite particles distributed over the whole yarn cross-section than that from the core of the sheath/core yarn. This result for the clothing measured using a thermal manikin was consistent with the higher heat retention rate (I) and the maximum surface temperature of the dispersed fabric than that of the sheath/core fabric. In addition, the thermal insulation of the dispersed and sheath/core fabrics was superior to that of the regular PET fabric, which revealed that the Al2O3/graphite particles imbedded in the dispersed and sheath/core yarns exerted a greater effect on the heat storage and release characteristics compared to that of the TiO2 particles in regular PET yarn. The Clo values of the dispersed and sheath/core fabrics under the light-on condition were much higher than those under the light-off condition, and furthermore, the difference of the Clo value between the sheath/core and regular PET fabrics under light-on condition was approximately 1.7 times greater than that under the light-off condition. These results revealed that the far-infrared rays emitted from the Al2O3/graphite particles imbedded in the sheath/core and dispersed yarns enhance the heat storage and release characteristics from the fabric under the light-on condition, i.e. under the sunlight.
Originality/value
The previously examined thermal wear comfort properties of the various inorganic particle-imbedded fabrics were measured with the fabric state, not clothing, which could not provide objective data related to the actual wearing performance of clothing.

Abstract
Purpose
This study aims to identify how and why chief learning officers (CLOs) build the learning organization. The study was undertaken in the conceptual framework of leadership and change by using the lens of the Marquardt Systems Model.
Design/methodology/approach
This exploratory study used semi-structured interviews with 20 participants. The purpose of the interviews was to understand the themes and subthemes associated with how CLOs define and build the learning organization, as well as the activities and strategies they use to build a learning organization.
Findings
Four major conclusions were drawn from the study: CLOs collaborate and encourage others to collaborate both within and outside of the organization; they assess and measure learning and development programs consistently; they seek and secure funding and resources; and they have a vision for the learning organization and realize that vision through strategy development and implementation.
Originality/value
This study is the first to provide comprehensive research on how CLOs build learning organizations, as well as the first to analyze this role using the Marquardt Systems Model.

Abstract
Purpose
Women in Western Europe wore empire style robes which were made with a light and thin fabric revealing their body. To stress the silhouette of their body, they applied oil to it or sprayed water on the robe so that it would cling to the body, and most women suffered from muslin disease, meaning flu and tuberculosis of the lungs in winter season. The purpose of this paper is to examine the thermal insulation of the robe with spencer jacket in dry and wet environment through thermal manikin experiments.
Design/methodology/approach
Three kinds of spencer jacket were made based on historical evidence and data, and experimental work for thermal insulation was conducted using a thermal manikin. The study measured the total thermal resistance of dress-jacket set: weight of the clothing before and after wetting, thermal insulation of the spencer jackets and set of clothing in dry and wet conditions, electric power consumption of the set of clothing in the wet condition and temperature inside the clothing and surface temperature of the wet set of clothing.
Findings
The thermal insulation of the robe with spencer jacket in the wet condition was in the range of 0.135-0.144 clo, which was about 80 percent lower than the range of values of 0.73-0.79 clo measured in the dry condition. This means that women felt uncomfortable in wetting condition or raining environment even when wearing the robe with a spencer jacket. Thermal insulation of clothing was dependent to the air gap under garment, clothing layers, ventilation through fabric and body part.
Originality/value
In this study, the thermal insulation of an empire style robe with spencer jacket in wet condition was measured using a dry thermal manikin, not with the sweating manikin. The authors measure the electric power consumption according to drying time of the clothing set at the body parts. In order to study the effect of different materials and clothing wetting, comparison experiments were conducted in dry and wet conditions using the rinse cycle of washing machine.

Abstract
Until recently, chlorine used to be an important chemical in bleaching process in paper industry, but as a result of environmental concerns, it is being replaced by chlorine dioxide. However, chlorine dioxide is more corrosive in certain conditions. Plant personnel, therefore need to better understand the reactions taking place in the changed media and search for more resistant materials. It is with this in mind that the present work was undertaken. The paper reports the electrochemical polarisation measurements performed on stainless steels 316L, 317L, 2205 and 254SMO in chlorine dioxide solutions to observe localised corrosion. The results have been analysed with reference to Pourbaix diagrams, taking into account the various chemical species present in the bleach solutions. Conclusions drawn from electrochemical tests have been compared with those from long‐term laboratory and plant tests. Materials options are proposed on the optimal choice of materials for bleach plants, in a context of probable corrosion performance, capital cost and mechanical strength.

The purpose of this paper is to examine differences between thermal insulation calculated by a global and a serial method using a thermal manikin, in comparison with human trials.
Abstract
Purpose
The purpose of this paper is to examine differences between thermal insulation calculated by a global and a serial method using a thermal manikin, in comparison with human trials.
Design/methodology/approach
A total of 150 single garments and 38 clothing ensembles were assessed using the manikin; 26 seasonal clothing ensembles were selected for human trials.
Findings
The results showed that total insulation of single garments was 16 percent higher in the serial method than in the global method. The difference was higher in garments with smaller covering area per unit garment mass (e.g. winter garments). For seasonal clothing ensembles, the serial values were 39.2 percent (0.18 clo) for spring/fall wear, 62.6 percent (0.15 clo) for summer wear and for winter wear 64.8 percent (0.69 clo) greater than the global values. The clothing insulation by the global method was systemically lower in all 26 seasonal ensembles than values by human trials, which suggests that the values by the global calculation can be more accurately corrected with human testing data.
Originality/value
The paper shows that values by the serial calculation were lower in spring/fall and summer ensembles but greater in winter garments than values collated by human trials. It suggests that the serial values had a lower validity when compared with thermal insulation values collated from human trials.

Abstract
Purpose
Competencies have come to play a central role in a wide range of settings in UK public and private sector contexts. This phenomenon is usually analysed but rarely recontextualised. The purpose of this paper is to identify the epistemological and ontological paradigms on which these approaches are couched in a British historical socio‐cultural context.
Design/methodology/approach
To put into light what this alternative perspective on competencies could add to reflection and practice, this paper realizes an in‐depth two‐year ethnographic study (employing participant‐observer methods) of a consultancy delivered training programme for customer service competency based vocational qualification in a water utilities company based in the north of England.
Findings
Based on a wide literature review on competencies, the first main result of this paper is to show that many of competencies approaches are underpinned by an empirical, pragmatic and ultimately modernistic, positivistic predilection. In an attempt to reappraise this rigid and highly structured representation of competencies, the paper draws on the resources of critical management approaches and notions of “lived experience”. The main empirical result is that competencies are richer than competencies (especially NVQs) usually suppose it and that critical perspectives are valuable in seeking to address these lacunae.
Originality/value
The paper offers an innovative insight to alternative dimensions of the experience of working with competency frameworks. Overall, a further value of this paper is to provide an assessment and a critique of the experience of competencies and vocational training in the UK. This recontextualisation underlines that competencies are weak at capturing and portraying the rich panoply of multifarious emotions and social interactions that take place in the workplace and everyday job life.
