Soil quality assessment based on carbon stratification index in different olive grove management practices in Mediterranean areas

In Mediterranean areas, conventional tillage increases soil organic matter losses, reduces soil quality, and contributes to climate change due to increased CO2 emissions. CO2 sequestration rates in soil may be enhanced by appropriate agricultural soil management and increasing soil organic matter content. This study analyzes the stratification ratio (SR) index of soil organic carbon (SOC), nitrogen (N) and C:N ratio under different management practices in an olive grove (OG) in Mediterranean areas (Andalusia, southern Spain). Management practices considered in this study are conventional tillage (CT) and no tillage (NT). In the first case, CT treatments included addition of alperujo (A) and olive leaves (L). A control plot with no addition of olive mill waste was considered (CP). In the second case, NT treatments included addition of chipped pruned branches (NT1) and chipped pruned branches and weeds (NT2). The SRs of SOC increased with depth for all treatments. The SR of SOC was always higher in NT compared to CT treatments, with the highest SR of SOC observed under NT2. The SR of N increased with depth in all cases, ranging between 0.89 (L-SR1) and 39.11 (L-SR3 and L-SR4).The SR of C:N ratio was characterized by low values, ranging from 0.08 (L-SR3) to 1.58 (NT1-SR2) and generally showing higher values in SR1 and SR2 compared to those obtained in SR3 and SR4. This study has evaluated several limitations to the SR index such as the fact that it is descriptive but does not analyze the behavior of the variable over time. In addition, basing the assessment of soil quality on a single variable could lead to an oversimplification of the assessment. Some of these limitations were experienced in the assessment of L, where SR1 of SOC was the lowest of the studied soils. In this case, the higher content in the second depth interval compared to the first was caused by the intrinsic characteristics of this soil's formation process rather than by degradation. Despite the limitations obtained SRs demonstrate that NT with the addition of organic material improves soil quality.

Towards conceptualizing reverse service supply chains

Purpose – Recognizing the heterogeneity of services, this paper aims to clarify the characteristics of forward and the corresponding reverse supply chains of different services. Design/methodology/approach – The paper develops a two-dimensional typology matrix, representing four main clusters of services according to the degree of input standardization and the degree of output tangibility. Based on this matrix, this paper develops a typology and parsimonious conceptual models illustrating the characteristics of forward and the corresponding reverse supply chains of each cluster of services. Findings – The four main clusters of service supply chains have different characteristics. This provides the basis for the identification, presentation and explanation of the different characteristics of their corresponding reverse service supply chains. Research limitations/implications – The findings of this research can help future researchers to analyse, map and model forward and reverse service supply chains, and to identify potential research gaps in the area. Practical/implications – The findings of the research can help managers of service firms to gain better visibility of their forward and reverse supply chains, and refine their business models to help extend their reverse/closed-loop activities. Furthermore, the findings can help managers to better optimize their service operations to reduce service gaps and potentially secure new value-adding opportunities. Originality/value – This paper is the first, to the authors ' knowledge, to conceptualize the basic structure of the forward and reverse service supply chains while dealing with the high level of heterogeneity of services.

GHIRS: integration of hotel management systems by web services

Nowadays web services technology is widely used to integrate heterogeneous systems and develop new applications. In this paper, an application of integration of hotel management systems by web services technology is presented. The Group Hotel Integration Reservation System (GHIRS) integrates lots of systems of hotel industry such as Front Office system, Property Management system, Enterprise Information System (EIS), Enterprise Information Portal system (EIP), Customer Relationship Management system (CRM) and Supply Chain Management system (SCM) together. This integration solution can add or expand hotel software system in any size of hotel chains environment.

Mortgages and bonds: the asset management practices of Australian life insurers to 1960

Recent studies of the experience of the British life insurance industry indicate that a period of transition, and the development of more diversified investment strategies, began in the interwar period. Australian life insurers lagged behind their British counterparts in the introduction of such strategies. This paper investigates why this was the case. It argues that in the Australian market there was both a lack of opportunity and incentive to broaden asset portfolios. However, this did not mean that asset management practices did not advance. Australian life offices became progressively more sophisticated in their approach to portfolio management during this period. Developments in the interwar period provided a grounding for post-war expansion into the equity market.

In the service of the society: the labour management practices of an Australian life Insurer to 1940

This article considers the labour management practices in use in the Australian life insurance industry during the inter-war period. Using the Australian Mutual Provident as a case study, it is argued that the specific human resource management practices evolved to deal with separate sets of problems arising from the functions of the life insurance business and the manner in which the principal/agent problem was manifested. The differing nature of work associated with the sales and management of life insurance fostered the development of primary and secondary labour markets in which the benefits flowing to one were superior to those accruing to the other.

Using multimedia and interactive games to enhance students' understanding of SCM

It is challenging to teach supply chain management (SCM) practices and technologies to tertiary students. This is because the back-end and highly dynamic processes can be difficult to visualise and because many students only have experience as a consumer. This paper reports the authors' experiences using a variety of multimedia and interactive enhancements we have used with our SCM learning materials: SCM business simulations; online learning modules with interactive games; and multimedia resources such as videos and animations. The paper also provides an overview of the challenges faced using these approaches, which gives rise to a number of future research opportunities. It also argues that these approaches can support educators with any epistemological view of learning. The paper makes a significant contribution because there has been little if any research into the use of these approaches in SCM education.

Encouraging small firm up-take of SCM using education: a future research agenda

The success of supply chain management (SCM) practices often depends on small firms in the supply chain adopting these practices, yet they are often reluctant to do so. The existing literature mostly explores SCM adoption barriers rather than approaches to encourage adoption. This paper argues that an educational perspective has promise, and proposes a research agenda which should guide future studies by all researchers studying small firm SCM up-take. The agenda encompasses the diversity of small firms, the major educational players, appropriate types of education approaches and the theoretical framework to underpin this research. The paper then gives an example of how this research agenda can be applied to a specific research project which will explore the impact of the Supply Chain Knowledge Centre (SCKC), a state of the art SCM education facility developed by GS1 Australia, on small firm SCM up-take.
