Development of an evaluation methodology for triple bottom line reports using international standards on reporting.

Abstract: The purpose of this article is twofold. First, evaluation scoring systems for triple bottom line (TBL) reports to date are examined and potential methodological weaknesses and problems are highlighted. In this context, a new assessment methodology is presented based explicitly on the most widely acknowledged standard on non-financial reporting worldwide, the Global Reporting Initiative (GRI) guidelines. The set of GRI topics and performance indicators was converted into scoring criteria while the generic scoring devise was set from 0 to 4 points. Secondly, the proposed benchmark tool was applied to the TBL reports published by Greek companies. Results reveal major gaps in reporting practices, stressing the need for the further development of internal systems and processes in order to collect essential non-financial performance data. A critical overview of the structure and rationale of the evaluation tool in conjunction with the Greek case study is discussed while recommendations for future research on the field of this relatively new form of reporting are suggested.

Handoff prioritization and decision schemes in wireless cellular networks: a survey

Abstract: Handoff is a key element in wireless cellular networks in order to provide quality of service (QoS) to the users and to support users' mobility. Handoff failure will result in the forced termination of an ongoing call. From the user's point of view, the service of a handoff request is more important, as the forced termination of an ongoing call is more annoying than the blocking of new calls. Therefore, in order to support QoS to the users and to provide ubiquitous coverage, the handoff procedure ought to be further investigated. This paper provides a comprehensive survey of the basic elements, the different types and phases of the handoff procedure. Moreover, particular interest has been given in the horizontal handoff execution phase by discussing and classifying the most recent handoff prioritization schemes into categories based on the concepts that these schemes adopt, e.g. channel reservation, handoff queueing, channel transferred, subrating, genetic and hybrid schemes and in the vertical handoff decision phase by presenting different decision algorithms.

Teachers' Burnout, Depression, Role Ambiguity and Conflict.

Abstract: The present study investigates issues associated with teachers’ burnout in primary education as related to depression and role conflict–ambiguity. At the time of the study the participants (562 teachers) were working in seventy nine (79) Primary Education State Schools in Greece (Athens and two prefectures in the southern part of the country). The results showed that of the three factors comprising the Burnout inventory (MBI, Maslach and Jackson, MBI: Maslach Burnout Inventory; manual research edition, 1986), (i.e., Emotional exhaustion, Personal accomplishment, Depersonalization) Emotional Exhaustion showed a statistically significant (positive) correlation with the factors that comprise: (a) the Scale of Depression (CES-D: Ensel, in: Lin et al. (eds.) Social support, life events and depression, 1986; Radloff, Applied Psychological Measurement 1: 385–401, 1977) such as Depressed affect, Somatic retarded activity and (b) Degree of Role Conflict (Role Conflict and Role Ambiguity Scale, Rizzo et al., Administrative Science Quarterly, 15:150–163, 1970, adapted in Greek by Koustelios and Kousteliou, Psychological Reports, 82:131–136, 1998); similarly, Positive affect (CES-D) and Degree of Role Clarity (Role Conflict and Role Ambiguity Scale) showed a statistically significant (negative) correlation with the same factor (Emotional exhaustion). Furthermore, a regression analysis performed with Personal accomplishment as the dependent variable showed that the (combined) factors of Role Ambiguity, Positive Affect and Somatic Retarded Activity contributed significantly to the prediction of the dependent variable; A third regression analysis performed with Depersonalization as dependent variable showed that Somatic Retarded Activity, Role Conflict, Positive Affect, Interpersonal Affect and Role Ambiguity contributed significantly to the prediction of this variable. Overall, the results showed that Greek teachers experience low-moderate levels of Burnout, Depression, Role conflict and Role ambiguity.

Public–private partnership projects in Greece: risk ranking and preferred risk allocation

Abstract: Project participants, through experience, have an initial perception and predisposition towards risk and the types of risks they are willing and able to undertake. This is equally true for parties interested in public–private partnership (PPP) projects. These initial positions have been registered for the major Greek PPP market stakeholders potentially involved in a PPP arrangement through a survey covering all candidate construction companies, interested financing institutes and a number of public sector entities to be involved in PPPs. Findings revealed that stakeholders were, for the majority of risks identified, in agreement as to preferred risk allocation. Risk allocation preferences for construction companies were compared with similar findings for the UK, a mature PPP market, indicating a possible learning/maturing process based on the particular country background. Conclusions add to other surveys carried out on the subject and should enable public sector clients to establish a more efficient fram...
