Vision technology is gaining more and more acknowledgement in the process industry as an effective way for a company to ensure high quality of production. After an introduction to vision technology, we will give a deeper description of the VisionSensor™, which is uniquely designed for on‐line integration in real‐world industrial environments. The description of the VisionSensor™ will encompass where the system can be used, how it works, comparing its merits with alternative techniques and finally a description of two case stories from the sugar and fertiliser industries.

Wonders whether companies actually have employees best interests at heart across physical, mental and spiritual spheres. Posits that most organizations ignore their workforce – not even, in many cases, describing workers as assets! Describes many studies to back up this claim in theis work based on the 2002 Employment Research Unit Annual Conference, in Cardiff, Wales.

The purpose of this paper is to investigate the influence of the potential of hydrogen (pH) and dissolved oxygen in artificial seawater on the passivation behavior of 316L stainless steel.

The corrosion behavior was studied by using electrochemical measurements such as electrochemical impedance spectroscopy and polarization curve. The passive films were characterized with X-ray photoelectron spectroscopy.

The polarization resistance of the passive film decreases as the pH value drops ascribed to the formation of much more point defects. The donor carrier concentration (ND) in the passive film formed in the deaerated condition is lower than that in aerated conditions. Nevertheless, this phenomenon is the opposite when the pH value is 1 due to the significant decrease of Fe oxides/hydroxides coupled with the stable content of Cr oxides/hydroxides species. In addition, the compositional variation of the passive film also leads to the changes of its semiconductor properties from N-type to bipolar type.

This paper shows the variation of polarization resistance, corrosion potential, passive film composition and semiconductor properties with the pH value and dissolved oxygen. The results can serve as references to the further study on crevice corrosion of 316L in seawater.

Public organisations face increasing challenges to attract young and highly qualified staff. Previous studies have shown that public service motivation (PSM) is associated with a higher propensity to apply for public sector jobs, but the implications from these findings for the design of the recruitment process are still unclear. The purpose of this paper is to investigate how differently framed recruitment messages (i.e. inspirational and rational) affect perceptions of person-job (PJ) and person-organisation (PO) fit, how these associations are moderated by PSM and how they translate into application intentions.

The authors conducted a survey experiment and tested the hypotheses in a sample of 600 students in Germany. The experimental stimuli were hypothetical job advertisements in which inspirational and rational messages on organisational missions and job tasks were varied.

Results show that recruitment messaging, as mediated by perceived PJ and PO fit, can increase application intentions depending on the framing of the messages. Inspirational framings are more effective in attracting personnel than rational framings, especially when such messages convey specific and extensive information about job tasks. The extent to which recruitment messages translate into perceptions of fit depends, in part, on the level of the applicant’s PSM.

By focusing on recruitment messages and their framings, this study is among the few that explore how human resource management can capitalise on previous findings of research on PSM. The findings have implications for the selection and presentation of information on organisational missions and job tasks in the recruitment process. In a more theoretical vein, results contribute to the emerging consensus on the role of perceived PJ and PO fit in the attraction to public sector jobs. The authors deepen this reasoning by introducing self-discrepancy theory to the field of public management.

This article discusses how integration processes in Denmark can be more efficiently supported by public libraries. The theoretical framework used in the research is connected to the notion of social capital and transnational spaces. From this point of departure, the authors do not view integration as a convergence of different value systems, but rather as an expansion and a diversification of the points of contact ethnic minority groups are developing within Danish society. The authors' basic conclusion is that public libraries will serve integration purposes more efficiently if they cease to be bound to integration concepts where the culture of countries of origin and that of an oversocialized actor are centrally placed.

Considering current development of Grey Systems Theory (GST), we can come up with the following thesis: practical applications are a dominant subject of research. Thus, what seems to be symptomatic for relatively young knowledge disciplines, the authors observe the presence of imbalance between the development of GST application tools and theory’s epistemological and methodological background. As for GST, epistemological and methodological problems are becoming visible especially in the issues of determining a clear criterion of demarcation of this kind of a theory from others. In other words, this problem can be reduced to the issue of a precise determination of what the category of a grey system and grey information is. This problem is of great importance for further development and popularisation of GST in the world of science. Realising its significance, the purpose of this paper is to create a general overview of Grey Systems epistemology and afterwards create axiomatic and formal frames for a category of greyness.

In order to achieve set goals, two research approaches were accepted. In the area of inference about epistemology of GST an approach characteristic of an analytical philosophy was used, whereas in the case of axiomatic and formal frames for a category of greyness the authors referred to terms of a set theory and the principles of a pragmatic logic.

The result of research is to formulate a concept of a grey system and a concept of grey information in the context of a process of cognition. Moreover, a function of greyness and other fundamental categories of GST will be defined in an axiomatic way.

The paper presents a new consistent frame for the issues of methodological and epistemological backgrounds of GST. An original concept is to refer in considerations to a newly proposed grey space. This space was used for a formal justification of such elementary categories as grey numbers, a weight function of whitenization or grey sequences. The value of achievements shown in the paper is underlined by the fact that proposed theoretical constructions require further development and they can potentially open up new research trends in the GST.
