A Decade of Integrated Reporting Studies: State of the Art and Future Research Implications

Purpose – Over the past decade, researchers have witnessed an exponential growth in the number of publications on IR. This paper aims to understand the state of the art of the research field and to highlight the areas where further academic research is needed, guiding developments in theory, research, policy and practices. Design/methodology/approach – The authors apply the dynamic literature review method called “Systematic Literature Network Analysis”, which combines systematic literature review and bibliographic network analysis. Furthermore, to overcome some of the limitations connected to the methodology, the authors integrate the literature with a manual content analysis of papers. Findings – IR adoption and practices and their determinants represent the most analyzed aspects of literature. Over time, attention has been paid to more specific issues, such as the relationship between IR and other disclosure mechanisms, IR quality and its assurance, the critical analysis of the IR framework and principles and difficulties in IR adoption. Although the literature on IR can be considered to be in its mature stage, many aspects are still under-researched, so there is plenty of space for future research. Originality/value – The authors propose the following main issues as subjects to be investigated in future studies: IR is not simply an evolution of sustainability reporting, but an innovative communication tool; the debate on who the recipients of value are (shareholders or stakeholders) and on what the definition of value adopted by IR is still remains an open issue; more attention should be given to the role of IR as a managerial tool, which could support strategy formation and communication, and influence internal processes of performance measurement and evaluation; what the future of IR will be in light of recent EU Corporate Sustainability Reporting Directive and new ISSB’s standards is still an open question. From a methodological perspective, little is known about structured approaches in accounting studies. The authors confirm how methodologies, such as that of this paper, may be exploited as a tool to support dynamic analysis for setting the agendas for future studies in the accounting field

Ofiuroideos del Cretácico Inferior de Patagonia: primer registro fósil articulado para el Mesozoico de América del Sur

The first articulated remains of ophiuroids for the Mesozoic of South America are described from the Lower Cretaceous of Neuquén Basin, Argentina. The taxonomic analysis allows the assignment of the material described herein to the extinct genus Ophiopetra. The specimens belong to a new species, but considering the poor preservation, a new name is not introduced, as it would be based on an incomplete diagnosis. Certain characteristics (e.g., the diameter of the disc, the width/height ratio of the vertebrae) suggest that these ophiuroids are paedomorphic specimens. In light of the latest classification of the Ophiuroidea, and new insights on the spine articulation microstructure of Ophiopetra lithographica presented herein, a transfer of Ophiopetra to the family Ophionereididae within the order Amphilepidida is proposed. This material expands the palaeogeographic record of this genus, since it represents the first remains of Ophiopetra described in the Southern Hemisphere. It is also the first Cretaceous record of the genus worldwide.Fil: Fernández, Diana Elizabeth. Consejo Nacional de Investigaciones Científicas y Técnicas.

Clay minerals of the Agua de la Mula Member - Agrio Formation- in a sequence stratigraphic model, in the Neuquén Embayment

Se realizó un estudio mineralógico, sedimentológico y estratigráfico del Miembro Agua de la Mula (Hauteriviano Tardío–Barremiano Temprano) de la Formación Agrio, en el ámbito paleo-geográfico del Engolfamiento Neuquino, provincia de Neuquén, Argentina. La información obtenida a lo largo de dos transectas orientadas en dirección Norte-Sur (localidades de estudio de Bajada del Agrio, Agua de la Mula, Cerro Rayoso y Mina San Eduardo) y Noroeste-Sudeste (localidades de estudio Loma La Torre y Caepe Malal) permitió reconocer importantes variaciones en el registro depositacional y post-depositación de dicha unidad. De las asociaciones de minerales de las arcillas (filosilicatos), se reconoció un neto predominio de illitas de politipo 2M1 y minerales interestratificados illita-esmectita (I/S) con ordenamiento ISII o R = 3 (menos de 15% de capas expansivas) de origen detrítico. Se documenta, también, en proporciones subordinadas clorita y caolinita tanto de origen diagenético como detrítico. De haber existido cambios paleoclimáticos contrastantes en las áreas fuente de sedimento, el tiempo de residencia no habría sido suficiente como para ser registrado ya que no se documentan variaciones en las asociaciones de filosilicatos de importancia que permitan realizar tales inferencias. Por su parte, la presencia de niveles con caolinita autigénica, ligados a superficies con significación estratigráfica indican que alteraciones eogéneticas, vinculadas con descensos relativos del nivel del mar y la incursión de aguas meteóricas que promovieron la caolinitización in-situ de los feldespatos. Tal interpretación se refuerza debido la presencia de bancos dolomitizados por encima de los niveles caolinitizados, sostenido a través de resultados de isótopos estables en dolomita (δ13C VPDB y δ18O VPDB) los que indican mezclas de aguas meteóricas y marinas al momento de la precipitación. Se reconocieron 32 litofacies sedimentarias que junto al análisis microfacial permitieron identificar seis asociaciones de facies con jerarquía de subambientes correspondientes a: rampa externa (distal y proximal), rampa media (distal y proximal) y rampa interna (distal y proximal). Se identificaron cuatro secuencias transgresivas-regresivas, que con, respecto al tiempo total de acumulación a partir de información de dataciones absolutas pre-existentes, se interpretan como relacionadas a secuencias depositacionales con jerarquía de cuarto orden, lo cual es marcadamente contrastante con interpretaciones previas.The Agua de la Mula Member (Late Hauterivian–Lower Barremian) of the Agrio Formation has been studied through mineralogical, sedimentologic and stratigraphic analyses in the Neuquén Embayment, Neuquén province, Argentina. The information was obtained from two transect oriented N-S (Bajada del Agrio, Agua de la Mula, Cerro Rayoso and Mina San Eduardo localities) and NW-SE (Loma La Torre y Caepe Malal localities) which permit recognition of significat depositional and post-depositional changes. Clay mineral association indicate that illite-2M1 polytype and interstratified illite-smectite (I/S) with ISII order o R = 3 (less than 15% of expanded components) are the predominating mineral phases, inherited from parental rocks. Also, Fe-chlorite and kaolinite are present but in a subordinate form and they are diagenetic and detrital in origin. Whether contrasting paleoclimatic changes occured in the hinterland, the residence time was insufficient to be documented in the clay mineral associations. Moreover, the presence of beds with authigenic kaolinite and linked to surfaces of stratigraphic importance indicate that eogenetic alterations related to relative sea-level fall promoted the incursions of meteoric water and the kaolinitization in-situ of feldspars. This interpretation is sustained by the presence of dolomitic beds where stable isotope data (δ^13C VPDB y δ^18O VPDB in dolomite) point to a mixture between normal marine and fresh meteoric water at time of deposition. The distinction and definition of 32 lithofacies together with the microfacies analyses permitted to recognize six facies associations corresponding to six types of depositional settings: outer ramp (distal and proximal), middle ramp (distal and proximal) and inner ramp (distal and proximal). Also, four fourth-order depositional sequences have been identified according to previous radioisotopic age determinations and constrated with previous stratigraphic models for the studied unit.Fil: Comerio, Marcos Alejandro.

Chinese students and personal tutorials in a British overseas campus: the strategic choices of emerging adults

Personal tutorials are an essential feature of student support in British universities, therefore they are duplicated on British overseas campuses. It appears that Chinese students are reluctant to seek help when they experience personal difficulties that affect their engagement with learning and their academic performance. Limited literature explores this phenomenon with relevant studies only focusing on Chinese students’ experiences abroad. Furthermore, these studies mainly refer to cultural factors related to traditional Confucianism to explain why these students do not engage with support structures. Drawing on the theory of Emerging Adulthood, this paper analyses the experiences of students on a Chinese branch campus of a British university. A mixed methods research approach was considered the most appropriate means of engaging with the participants; a quantitative study was used in an exploratory fashion to provide unbiased insight into student opinion and experience, and a qualitative content analysis was used to analyse participants’ comments in the open field questions. The findings reveal an alternative portrayal of the “Chinese Personal Tutee”, distant from the traditional Confucian model still predominantly used as an analytical tool in research on Chinese youth. Chinese students on an international campus strategically select their sources of help and prefer to build symmetrical relationships with personal tutors based on personal goals rather than asymmetrical relationships based on ‘care’ provided by adults. Consequently, ‘transnational’ personal tutorial systems pursuing Chinese students’ successful engagement ought to be conceptualised by considering their emerging adulthoods and by respecting their sense of agency

Integrated disaster recovery: Linking health care and disaster case management

In long-term recovery from natural disasters, the federal government helps to rebuild infrastructure, but individuals face a chaotic and uncoordinated assembly of state and local programs, insurance coverage, and assistance from nongovernmental organizations. The Federal Emergency Management Agency and other organizations have utilized case management, which matches individual needs for housing, health care, employment, and education, etc. with appropriate resources, to coordinate disaster recovery. However, these efforts have had uneven results. Case management limitations include: inability to identify and locate all those in need, implementation barriers, inability to scale services for large urban disasters, and poor sustainability. Linking disaster recovery case management with health care organizations, especially those with pre-existing health care case management programs, is a practical, scalable and sustainable approach to integrating the many aspects of disaster recovery and is a way for building community resilience before and after disasters
