Stakeholder Perspective of Corporate Governance and CSR Committees
CSR is becoming more and more important, and many companies have taken meaningful steps to improve their corporate governance according with a stakeholder perspective. An emerging board-level figure is the CSR or sustainability committee. The increase in complexity induced by the responsible business conduct and the growing importance of the effective management of reputational risk, highlight the usefulness of committees with proposing and consultative functions on CSR issues. These committees are relatively new governance structures, whose affirmation is slow, and can provide a useful contribution to the integration of social responsibility into strategy setting and the business model

A New Approach to Bicarbonate Addition during Hemodialysis: Testing Model Predictions in a Patient Cohort
In this study, we present a new protocol for kidney replacement therapy (hemodialysis), based on an explicitly solvable mathematical model. With current protocols, the high and constant level of bath bicarbonate (HCO3-) used to prevent metabolic acidosis leads to very rapid delivery of HCO3- into the patient during the first part of the therapy. This rapid alkalinization elicits a robust buffer response that, paradoxically, consumes more HCO3- than is added during the remainder of the treatment. In previous studies, we developed an analytical model that allows one to quantify these events and tested alternative protocols manipulating the rate of rise in blood bicarbonate concentration (HCO3-). The protocol tested in this paper enforces a more gradual increase in blood HCO3-, by means of a model-based staircase adjustment of bath HCO3-. Model equations predict a reduction of buffer response and rate of organic acid production. These predictions are tested in 20 stable outpatients receiving hemodialysis. We find that the proposed protocol achieves the desired profile of blood HCO3- with good accuracy and reduces the total buffer response by 1/3 and the rate of lactic acid production by at least 1/4, as compared to conventional therapy. Although more studies are needed, we believe that our work will pave the way for a more rational approach to correction of acidosis during hemodialysis. Article Highlights •Our study tests an analytic model designed to enforce a more gradual rate of bicarbonate delivery during hemodialysis.•Using our model, we show that we can reduce the excessive buffer response and lactic acid production that occur with the conventional approach.•We demonstrate that our model can provide a rational approach to bicarbonate addition during treatment
T-accessibility for Nonlinear Time-Delay Systems: The general case
Following the results recently obtained for nonlinear driftless systems affected by constant commensurate delays, a partial characterization of t - accessibility is provided for general nonlinear time-delay systems affected by constant commensurate delays. Conditions are given for this new property. The results are stated using the differential representation of time-delay systems

Responsiveness
Responsiveness refers to the ability to public administration and private firms to be accountable toward stakeholders about their ability to achieve their interests and expectations. The concept of responsiveness is strictly connected with the concept of responsibility, this last referred to the motivations that lead an organization to use resources in the interest of the resources’ owners.
Since the Eighties of the last Century the reform movements in the public sector emphasized the importance to overcome the mere compliance to formalized processes and procedures towards a more citizens’ needs and expectations centred approach.
Also in the private sector, the debate about social responsibility starting in the Sixties of the last Century has resulted in the belief that responsiveness is not limited to the communication activities by companies, but it expresses the global corporate responsibility that is leading the business according with the awareness of stakeholders’ expectations and their engagement in activities and strategies.
Therefore, the spread of concepts as social responsibility and sustainability induces a new way to interpret both the organizations’ responsibility, embracing economic, social and environmental impacts of their actions, and the organizations’ responsiveness, moving from the capability to response to external pressures and expectations to a more proactive approach as the stakeholder engagement
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
