Several process stages in the pulp and paper industry are undergoing changes. This is done partly for optimization, and partly to discontinue the use of substances hazardous to the environment. A side effect of these measures is that the problem of corrosion has increased. Explains why certain environments in the pulp and paper industry represent corrosion risks, with some examples given of corrosion failures, and suggests appropriate materials for these process stages.

The purpose of this paper is to introduce the special issue and outline its major themes and challenges, their relevance and the research opportunities the field presents.

The paper reviews prior literature and outlines the need to view public procurement as a policy tool to introduce the contributions to this special issue.

Public procurement has been consistently used to further public policies in a wide range of fields. The collection of articles in this special issue contributes to a broader understanding of the role and potential of public procurement in delivering desired policy outcomes in society. The articles show that public procurement largely has strategic aspirations, and its potential to deliver on wider societal issues is attractive to policy makers. The issues raised in this collection of articles, however, also demonstrate that public procurement often lacks strategic maturity and critical issues, notably around how to demonstrate and evaluate its impact and “success”.

This paper aims to stimulate interdisciplinary research into the role of public procurement as a policy tool and its ability to achieve public value.

This paper discusses theoretical and empirical findings that highlight the importance of public procurement for achieving public value. The special issue examines the interdisciplinary literature on public procurement and shows how it is being used to achieve public value.

Recent studies have classified ecotourism behaviour into specific components like site-specific ecological, pro-environmental and environmental learning behaviour. However, the role of materialism in generating these types of behaviour is not clearly understood. Materialism might also affect tourists' environmental engagement. Hence, this study embarks on exploring these research gaps.

All the constructs were operationalized as first-order factors based on extant scales of measurement. After suitable pretesting, the study was able to collect 122 valid responses. The responses were analysed using partial least squares (PLS).

Results suggest that environmental engagement and environmental learning behaviour have prominent roles as enablers. Furthermore, the importance of materialism is not statistically significant and requires further investigation.

While the study showed that environmental engagement is a crucial precursor for the development of different types of ecotourism behaviour, it also has limitations. First, the study tested the validity of the proposed associations based on the perceptual responses of 122 tourists who are interested in participating in ecotourism. However, this may lack generalizability. Future research can take a common set of tourists or a specific destination and execute a longitudinal analysis to better understand the way ecotourism behaviour has evolved over time at a destination. This would in turn help the local people and tour planners to develop tourism packages and events.

As tourists are interested in environmental learning, they are eventually expected to take care of the destination environment in terms of protecting it in every form. This may include reporting of any environment damaging activity, for example, activities that can enhance environmental pollution, etc.

Materialism hinders the environmental conservation spree of tourists, when they indulge more in shopping and leisure trips. Hence, for destination planners it is very important to hold complementary events in addition to the main event to highlight the dire need of involving in ecotourism activities.

The study is of significant contribution for researchers and practitioners as it develops the antecedents and consequences of environmental learning behaviour. Furthermore, this study has implications for managers working for sustainability of tourism destinations.

Many British employers are less than enthusiastic about the Government's proposals to abolish the 26 wages councils which set statutory minimum wage rates for 2.5 million employees. In its response to the Department of Employment's Wages Councils: 1988 consultation document, the Institute of Personal Management continues to reject a “blanket” approach of total abolition of all wage's councils. The I.P.M.'s view, first formed in 1982 after a major review of the operation of wages councils, is in line with the recommendation of the House of Commons Employment Committee in 1985 that it is right to review and reform but not abolish wages councils.

The purpose of this paper is to analyze how local and central authorities choose between lowest price and more complex scoring rules when they design supplier-selection mechanisms for public procurements. Five hypotheses are tested: a high level of cost uncertainty and highly non-verifiable quality makes the use of the lowest-price supplier-selection method less likely. Organizational habits and transaction-cost considerations influence the choice of mechanism. Strong quality concerns make complex rules more likely.

The analysis departures from normative theory (rational choice) and is based on the regression analysis and survey data comprising a gross sample of 40 contracting authorities and detailed information about 651 procurements.

More complex scoring rules are used more often when the authority is uncertain about costs and about delivered quality. Authority effects are also found to directly and indirectly influence the choice of supplier-selection method, suggesting that tendering design is partly driven by local habits and institutional inertia.

The authors argue that, from a normative point of view, lowest price is an adequate method when the degree of uncertainty is low, for example, because the procured products are standardized and since quality can be verified. When there is significant cost uncertainty, it is better to use the so-called economically most advantageous tender (EMAT) method. (Preferably this should be done by assigning monetary values to different quality levels.) If there is significant uncertainty concerning delivered quality, the contracting authority should retain a degree of discretion, so as to be able to reward good-quality performance in observable but non-verifiable quality dimensions; options to extend the contract and subjective assessments of quality are two possibilities. The main findings are that EMAT and more complex scoring rules are used more often when the contracting authorities report that they experience substantial uncertainty concerning delivered quality and actual costs and that these factors tend to decrease the weight given to price, in line with the predictions. However, the authors also find that this result is mainly driven by variations between authorities, rather than by between-products variation for the same authority. This is from a training of professionals and regulation perspective of policy relevance.

Contract allocation based on habits rather than rational ground could implicate the waste of resources (tax payers money) as it adventures the matching of the preferences of the public sector (the objective, subject matter, of the procurement) and what the potential supplier offers in its tender.

Although the principles for supplier selection are regulated by law they give the contracting authority substantial freedom in designing the scoring rule and in choosing what quality criteria to use. The tension between different objectives and the more general question whether the choices made by authorities reflect rational decision making or institutional inertia together motivate the current study. While the design of the supplier-selection mechanism is an important consideration in procurement practice, it has attracted relatively little attention from the academic community.

Purpose: The purpose of this chapter is to provide research-based information to foster positive discussions about the need for phonics and phonemic awareness instruction in the primary grades. In order to read, students must possess secure knowledge of the alphabetic principle (i.e., that speech sounds are represented by combinations of letters in the alphabet) as well as the ability to aurally separate the distinct sounds (phonemes) that make up words.

Design: In this chapter, the authors provide essential definitions of phonics and phonemic awareness terms, highlight peer-reviewed research and best instructional practices, and clarify findings in relation to the recently renewed controversy over how to effectively teach reading to young children. The authors draw from respected research journals and years of classroom experience to provide recommendations to literacy teachers.

Findings: Explicit, systematic phonics instruction is crucial for beginning readers because most children will not intuit phonics concepts. To set the stage for phonics instruction (connecting speech sounds with their written representations), students must understand how to separate sounds in words. Therefore, instruction in phonemic awareness must be given independently of alphabetic representations; that is, students need to be able to hear the distinct sounds before mapping them onto written words. Once a student has mastered this understanding, however, instructional time need not be devoted to its development.

Practical Implications: This chapter contributes to the literature on phonics and phonemic awareness by clearly explaining the differences between the two concepts and their necessary inclusion in any beginning reading program. It includes practical activities teachers can use to develop these understandings in the classroom and provides research evidence to support their use.

A review essay on Ronald Findlay, Lars Jonung and Mats Lundahl, eds. Bertil Ohlin: Centennial Celebration (1899–1999). Cambridge, MA: MIT Press, 2002. Pp. xvi, 546. $60.00. The Swedish economist Bertil Ohlin was born in 1899 and died in 1979. Less than half of his professional life he spent as a full time academic scholar in economics. He was a student at the University of Stockholm and was supervised by his teachers, Gustav Cassel and Eli Heckscher. In 1922, Ohlin presented his licentiat thesis where he set out the ideas later conceptualised as the Heckscher-Ohlin model. Two years later, in 1924, he took his doctoral degree under Cassel with a dissertation simply called Handelns teori (The Theory of Trade). A longer version of this dissertation was later published in English as Interregional and International Trade (1933). This work made him a famous trade theorist in a line of tradition going back to Ricardo and Torrens. Paul Samuelson in 1941 coined and immortalised the term “the Heckscher-Ohlin theorem” which he and Wolfgang Stolper developed further in a famous article in the Review of Economic Studies (1941) entitled “Protection and Real Wages.” Already at the age of 26 the bright young man Ohlin became a professor in economics at the University of Copenhagen and five years later he was appointed to a chair in the same subject at Handelshogskolan (The Stockholm School of Economics) in Stockholm.

This article offers a new perspective on assessing the status of women. It focuses on female endangerment and inequality among women as new dimensions of development and change. The article examines concepts of gender inequality and empowerment offered by the United Nations Development Programme (UNDP). The case of Nepal is discussed becasue of its serious neglect and deprivation of women. It is argued that while gender gaps matter, disparities among women are equally important constraining the country’s prospects of growth. The study presents a comparative analysis with other South Asian nations.
