Positively negative: the impact of negativity upon the political consumer

• For years there has been an ongoing debate as to the role and impact that ‘marketing’ has had on politics. Yet, it is the case that many of the concepts associated with the field of marketing have real relevance and have, in fact, been employed within the field of political campaigning for many decades. This is an empirical paper that focuses upon the concept of political brands and the impact that current trends in campaign strategy, and in particular the growth and continued use of negative campaigning, have upon them. Using a constructivist grounded theory approach, the implications associated with such activity are examined and, in particular, its effect upon the consumer/brand relationship.
• Within the consideration of the results, it becomes clear that political brands' use of negative campaigning is somewhat shortsighted; offering short‐term gains but at the cost of long‐term damage not only to their brand image but also to the wider democratic system as it stands. In a search for political ‘brands’ that more effectively meet their needs, there appears a tendency for political consumers to now look outside of the conventional political sector. The emergent concept of the ‘negative brand’ is explored together with the implications for political consumers, political brands and the wider field of conventional party politics.

Public–private partnerships: lessons from the British approach

British governments have for many years sought to move activities from the public to the private sector. For the past decade, this has included the provision of public services not only operated but also financed by the private sector. In 2000, these private finance initiative (PFI) projects were incorporated into a wider programme of public–private partnerships (PPPs). Compared to conventionally financed procurement, the PFI approach has brought both benefits and costs. The balance of advantage is often unclear, and at the strategic level the main drivers appear still to be ideology and accounting. However in its practical application many useful lessons have been drawn and applied.     

Legal Regulation of the Obligation of Employers to Provide Social Support to Employees in the Polish Legal System

The aim of the article is to present the Polish legal regulations concerning the obligation of social support to employees by employers, including the rich axiological layer having its source not only in socialist history of this country, but also in the legal principles expressed in the current Constitution. This issue may be interesting and inspiring in particular for people who, in order to better protect employees, support broader state interference in the market economy. The abovementioned obligation was regulated by the Polish legislator by the Act (and therefore for many employers is imperative) and formulated very widely (on both the objective and subjective scope). For this reason, Polish labor law, to the extent presented in this article, is in many ways unusual, compared to other legal systems, but it seems that it is still not known to a wider group of specialists dealing with labor law in capitalist countries. The paper also presents the analysis of the specific legislative solutions within the scope of the topic; for example the role of trade unions in the process of disbursement of funds from the social fund. The whole discussion is complemented by a consideration of the implementation of the social obligation to support workers by employers on the example of University in Szczecin (one of the largest universities in Poland).     

Ethnic minority business and the employment of illegal immigrants

Based on detailed case histories of South Asian workers and their co-ethnic employers in the West Midlands clothing and catering industries, this paper examines the use of illegal immigrant labour in small ethnic minority firms and attempts to tease out its implications for the migrants themselves, their employers and the broader national interest. To establish a proper context, we begin with a review of the recent literature on the structural changes – principally the confluence of globalization and post-industrialism – which have generated a seemingly unstoppable flow of labour migration; and the official state policies that have forced much of it underground. Our own case histories are seen as one of countless local expressions of this clash between economic and political imperatives, a clash which effectively criminalizes employers and workers for providing a positive economic and social contribution to the wider good. In the present case, it is only by employing immigrant labour that struggling entrepreneurs can survive in hyper-competitive sectors of the economy and the stark choice is between official tolerance of law-breaking or driving many of these enterprises to the wall.

Promoting competitive markets: The role of public procurement

The study presented here examines how public procurement agencies address establishing and maintaining competitive markets; a topic still in its academic infancy. Cases are used to address impediments and improve understanding of strategic priorities in managing for competitive markets. Public policy academics have observed many competing policies in the wider public sector. Specifically, this paper identifies a need for research on supplier incentives at a market level, on the post contract management of suppliers and as an important sub-set, key supplier relationship management, along with professional development.
