Effects of ground surface permeability on the growth of urban linden trees

Street trees are an important part of urban vegetation due to their provisioning of different types of ecosystem services such as local climate regulation and contribution to aesthetical and recreational values. In order to provide these services, urban trees need to endure many stress factors not present in natural environments, such as the widespread use of impervious surfaces in the vicinity of street trees. However, few studies have evaluated the effect of this potential stress factor on urban tree growth. The aim of this study was therefore to investigate how ground surface permeability affects stem and current-year shoot growth of linden (Tilia europaea) street trees in Gothenburg, Sweden. We found that a small fraction of permeable ground surface in the vertically projected tree crown area caused lower stem growth and strongly suppressed current-year shoot growth. This finding can guide future city planning, demonstrating that the vitality of street trees is compromised when the permeable surface area in the vicinity of the tree is small.     

Corporations and the State in the Global Era: The Case of Seaboard Farms and Texas*

Abstract Employing the case of the expansion and regulation of hog confined animal feeding operations (CAFO) in Texas combined with the actions of the transnational agri‐food corporation Seaboard Farms, Inc., this paper probes the relationship between the state and corporations in the global era. It specifically investigates the ability of the state to control agri‐food corporations in a context in which the hyper‐mobility of capital has increasingly allowed corporations to by‐pass state regulations and requirements. Salient literature is reviewed by grouping it into three camps: the first views the state as largely controlled by corporations; the second stresses the powers left to the state and the fact that corporations need state assistance to successfully operate in the current global economy; and the third acknowledges the crisis of the nation‐state under globalization but maintains that the state has retained some ability to resist globalization forces. The case study documents the expansion of Seaboard Farms' hog operations in the Panhandle Region of Texas and nearby states and its interaction with local and state governments and agencies. The article indicates that the relationship between transnational corporations and the state is contradictory. Its source rests on the fracture between varying postures maintained by the state and the relatively homogenous behavior of the CAFO corporations. The case also reveals that the state's limited control of corporate actions is facilitated by state strategies; that corporate actions are successful if corporations enlist the cooperation of the state; and the state is able to control resistance and legitimize its actions to its constituencies. These conditions, however, do not prevent the emergence of anti‐corporate resistance at local and state levels. In the search for new forms of socioeconomic development, local residents and their leaders should be aware of corporations' ability to affect state action, state postures that favor corporate designs, and the fact that successful opposition to corporate designs can be, and is, carried out.     

SMEs and Marketing: A Systematic Literature Review

This paper presents a systematic review of recent academic literature analysing the role, organization and management of marketing activities in small and medium‐sized enterprises (SMEs). To this end, 310 articles published between 2006 and 2015 in 69 main journals devoted to small firms/entrepreneurship and management/marketing fields were analysed. This review shows that SMEs’ marketing has received great attention in both management and marketing literature in recent years. Findings reveal, on the one hand, the emerging role of networks and information and communication technologies in marketing behaviour by SMEs, and on the other hand a research gap in terms of specific marketing practices. Entrepreneurial marketing has been used as the main conceptual framework in reviewed studies, even if findings overall still point out a distance between the theoretical bases of reviewed contributions and the study of SMEs’ marketing behaviour and practices. Therefore, future research on the role of resources, relationships and networks could benefit from the combination of theories developed within the field of entrepreneurship with other approaches such as the resource‐based view, the dynamic capabilities theory and the Industrial Marketing and Purchasing (IMP) framework.     

Looking at the IPO from the “top floor”: a literature review

This article aims to assess the current situation and the evolution of the literature on the role of top level decision-makers in initial public offerings. The article combines bibliometric and qualitative reviews of 147 articles published in 57 journals until 2015. Findings show that the debate on the role of top-level decision-makers in initial public offerings has followed an irregular pathway. Research attention has moved from studies on the actors and the dynamics of going public to a focus on the strategic implications of initial public offerings. The paper is a good starting point for future policy-making interventions designed to support top-level decision-making. By enhancing awareness of the strategic role of initial public offerings, we hope to improve the governance practices associated with them. The paper also sheds light on the importance of fostering the corporate transparency of top-level decision-making in firms going public, as an additional tool to increase investors’ trust and attract financial resources. Finally, the paper provides a comprehensive overview of the academic field, examining research trends and the evolutionary pattern. It also suggests future research avenues by identifying un(der)explored issues to advance knowledge on the topic.     

A micro analysis of the macro differences in refusal risk among metropolitan areas. The case of the Italian multipurpose survey

Although still modest, non response rates in multipurpose household surveys have recently increased, especially in some metropolitan areas. Previous analyses have shown that refusal risk depends on the interviewers' characteristics. The aim of this paper is to explain the difference in refusal risk among metropolitan areas by analysing the strategies adopted in the recruitment of interviewers through a multilevel approach. The Annual Survey on Living conditions is a PAPI survey of the "Multipurpose" integrated system of social surveys and it represents our data base. For non responding household, data on non response by reason, municipality and characteristics of the interviewer are available. The results highlight that those cities recruiting interviewers mainly among young students have a higher refusal risk. These results are particularly important as they indicate that recruitment strategies may have a substantial impact on non sampling errors.

THEORIES OF THE STATE: THE CASE OF LAND REFORM IN ITALY, 1944–1961

This article examines the case of land reform in Italy from 1944 to 1961 in relation to the role of the State in capitalism. Through an analysis of recent debate on the capitalist State, it offers an investigation of the generation and outcomes of the process of land reform. It is important to note that the social pressure exerted by landless peasants and farm workers for the redistribution of land and the dissolution of the dominant social bloc generated the conditions for a land reform that only partially satisfied the needs of the agricultural working class. Simultaneously, the mediation of the State enhanced the overall interests of the domestic bourgeoisie. In this context, land reform produced contradictory results that favored the processes of accumulation of capital and legitimation of social dissent.     

Global Agro-Food Corporations and the State: The Ferruzzi Case

The relationship between transnational corporations (TNCs) in the agro-food sector and the nation-state in the context of global post-Fordism is examined through a case study of recent events involving the Ferruzzi transnational corporation. TNCs have a complex and contradictory set of relations with the state that are affected by competition among TNCs, by TNCs' internal disagreements, and by the fragmented nature of the state. The state assists TNCs through formal and informal channels. In this specific case, the informality of the system is underscored by the openly illegal arrangement that was operated for years by Ferruzzi officials and members of the officialdom of the state. However, the state also has the capacity to counter the actions of TNCs and to enforce the interests of subordinate groups.     

An R package for the simulation of correlated discrete variables

A package for the stochastic simulation of discrete variables with assigned marginal distributions and correlation matrix is presented and discussed. The simulating mechanism relies upon the Gaussian copula, linking the discrete distributions together, and an iterative scheme recovering the correlation matrix for the copula that ensures the desired correlations among the discrete variables. Examples of its use are provided as well as three possible applications (related to probability, sampling, and inference), which illustrate the utility of the package as an efficient and easy-to-use tool both in statistical research and for didactic purposes.
