Background The practice of reading and discussing literature in groups is long established, stretching back into classical antiquity (Fischer, 2004). While benefits of therapeutic reading groups have been highlighted, research into participants’ perceptions of these groups has been limited (Walwyn & Rowley, 2011). Aims To explore the experiences of those attending therapeutic reading groups, considering the role of both the group, and the literature itself, in participants’ ongoing experiences of distress. Method Eleven participants were recruited from two reading groups in the South East of England. One focus group was run, and eight individuals self selected for individual interviews. The data were analysed together using a thematic analysis drawing on dialogical theories. Results Participants described the group as an anchor, which enabled them to use fiction to facilitate the discussion of difficult emotional topics, without referring directly to personal experience. Two aspects of this process are explored in detail: the use of narratives as transportation, helping to mitigate the intensity of distress; and using fiction to explore possibilities, alternative selves and lives. Conclusions For those who are interested and able, reading groups offer a relatively de-stigmatised route to exploring and mediating experiences of distress. Implications in the present UK funding environment are discussed.

This research examines media integration in China, choosing two Chinese newspaper groups as cases for comparative study. The study analyses the convergence strategies of these Chinese groups by reference to an Role Model of convergence developed from a literature review of studies of cases of media convergence in the UK – in particular the Guardian (GNM), Telegraph Media Group (TMG), the Daily Mail and the Times. UK cases serve to establish the characteristics, causes and consequences of different forms of convergence and formulate a model of convergence. The model will specify the levels of newsroom convergence and the sub-units of analysis which will be used to collect empirical data from Chinese News Organisations and compare their strategies, practices and results with the UK experience. The literature review shows that there is a need for more comparative studies of media convergence strategy in general, and particularly in relation to Chinese media. Therefore, the study will address a gap in the understanding of media convergence in China. For this reason, my innovations have three folds: Firstly, to develop a new and comprehensive model of media convergence and a detailed understanding of the reasons why media companies pursue differing strategies in managing convergence across a wide range of units of analysis. Secondly, this study tries to compare the multimedia strategies of media groups under radically different political systems. Since, there is no standard research method or systematic theoretical framework for the study of Newsroom Convergence, this study develops an integrated perspective. The research will use the triangulation analysis of textual, field observation and interviews to explain systematically what was the newsroom structure like in the past and how did the copy flow change and why. Finally, this case study of media groups can provide an industrial model or framework for the other media groups.

This study considers the literature on the persistence of business groups in developed economies and analyzes the Portuguese case. The reconstruction of the largest business groups assembles information relevant to define characteristics that enable them to thrive. Increasing internationalization, more specialization in core activities and family control define these types of big businesses. New sectors also emerge as a characteristic of these business groups when compared to the ones existing 40 years ago.

The difference between the statutory and effective tax rate for listed groups is a complex variable influenced by a variety of factors. This paper aims to analyze whether this difference exists for listed groups in the German market and tests which factors have an impact on it. Thus the sample consists of 130 corporations listed in the three major German stock indices. The findings suggest that the companies that pay less than the statutory rate clearly outweigh the ones that pay more, and that the income earned from associated companies has a significant impact on this difference.

This paper aims to provide a model that allows BPI to measure the credit risk, through its rating scale, of the subsidiaries included in the corporate groups who are their clients. This model should be simple enough to be applied in practice, accurate, and must give consistent results in comparison to what have been the ratings given by the bank. The model proposed includes operational, strategic, and financial factors and ends up giving one of three results: no support, partial support, or full support from the holding to the subsidiary, and each of them translates in adjustments in each subsidiary’s credit rating. As it would be expectable, most of the subsidiaries should have the same credit rating of its parent company.

This article introduces the Dyadic Coping Inventory (DCI; Bodenmann, 2008) and aims (1) to investigate the reliability and aspects of the validity of the Italian and French versions of the DCI, and (2) to replicate its factor structure and reliabilities using a new Swiss German sample. Based on 216 German-, 378 Italian-, and 198 French-speaking participants, the factor structure of the original German inventory was able to be replicated by using principal components analysis in all three groups after excluding two items in the Italian and French versions. The latter were shown to be as reliable as the German version with the exception of the low reliabilities of negative dyadic coping in the French group. Confirmatory factor analyses provided additional support for delegated dyadic coping and evaluation of dyadic coping. Intercorrelations among scales were similar across all three languages groups with a few exceptions. Previous findings could be replicated in all three groups, showing that aspects of dyadic coping were more strongly related to marital quality than to dyadic communication. The use of the dyadic coping scales in the actor-partner interdependence model, the common fate model, and the mutual influence model is discussed.

This study explores the impact of relative size on the intra- and intergroup attitudes of groups who either share a language or have a different language. For that purpose, we examined international attitudes, comparing a small nation, Switzerland, and two larger nations, Germany and France. We found support for the assumption that large neighbouring nations pose a threat to the smaller nation's identity, especially when they are linguistically similar. Consequently, in line with Tajfel's Social Identity Theory (1978), the smaller nation's inhabitants evaluate those of the larger nation less positively, liking them less and perceiving them to be more arrogant than vice versa. By investigating the special case of the French-speaking and the German-speaking Swiss as linguistic groups within their own nation we were able to demonstrate that these groups seek support with the larger-linguistically-similar nation to defend themselves against the more direct in-country threat to their identity. They acknowledge the similarity with the larger nation, yet keep defending their social identity by expressing a dislike for this perceived similarity.

This qualitative study examined collective learning within nursing clinical groups. Specifically, it explored the influence of the individual on the group and the impact of the group on the individual. The study was organized using the concepts from Debbie Kilgore's theory of collective learning (1999). The sample consisted of 1 8 second-year university nursing students and 3 clinical instructors. Data were collected via individual interviews with each participant and researcher's observations during a group conference. The interviews were tape-recorded, transcribed, and analyzed using key concepts from Kilgore's framework. Several interesting findings emerged. Overall, it appeared that individual components and group components contributed to the quality and quantity of collective learning that occurred in the groups. Individually, each person's past group experiences, personality, culture, and gender influenced how that individual acted in the group, their roles, and how much influence they had over group decisions. Moreover, the situation which seemed to cause the greatest sense of helplessness and loss of control was when one of their group members was breaking a norm. They were unable to deal with such situations constructively. Also, the amount of sense of worthiness (respect) and sense of agency (control) the member felt within the group had an impact on the person's role in group decisions. Finally, it seemed that students felt more connected with their peers within the clinical setting when they were close with them on a personal and social level. With respect to the group elements, it seemed that the instructors' values and way of being were instrumental in shaping the group's identity. In group 2, there were clear examples of group consciousness and the students' need to go along with the majority viewpoint, even when it was contrary to their own beliefs. Finally, the common goal of passing clinical and dealing with the fears of being in the clinical setting brought solidarity among the group members, and there seemed to be a high level of positive interdependence among them. From the discussion and analysis of the findings, recommendations were given on how to improve the learning within clinical groups.

This research is qualitative in nature and has explored, by means of interviews, the '^^ experiences of 10 men in their roles in caring for their spouses with Alzheimer Disease (see glossary) in their homes. Additional data were collected by attending 3 formal support group meetings and one informal meeting of a group of men who brought their wives to a support group meeting for their wives with AD. The data retrieved supported the assumption that education about the disease, utilization of formal community support services, and attendance at caregiver support groups or programs can assist healthy male caregivers in caring for their wives with AD in their homes.

The fragmentation processes in the mass spectra of a series of organophosphorus, organochlorine, thio and dithiocarbamate as well as a number of miscellaneous pesticides have been studied i n detail by using the Bendix timeof- flight, MS-12 single-focussing and MS-30 double-focussing mass spectrometers. Interpretation of all the spectra have been presented; their mode s of dissociation elucidated, aided by metastable transitions wherever possible and the structures of the various f ragmentation species postulated wherever f easible. The fragmentation mechanisms are based on the concepts of inductive, resonance and steric ef~ects. Multiple bond cleavages accompanied by simultaneous bond formation and rearrangement reactions involving cycli c t r ansition states have clarified t he formation of various ions . Due emphasis has been placed on the effect of the functional groups or substituents in altering the mass spectral behaviour of the pesticides as they form the basis for the identifi cation of the otherwise identical pesticides. The organophosphorus pesticides which have been studied include i) the phosphates (eg: DDVP and Phosdrin ); ii) phosphorothionates (eg: Parathion, 0-2, 4 dichloro phenyl 0, O-diethyl thionophosphate); iii) phosphorothioites (eg: Tributyl phosphorotrithioite); i V) phosphorothioates (eg: Ethion) and v) phosphorodithioates (eg: Carbophenolthion). Cleavages and rearrangements of the ester moiety dominate the spectrum of phosdrin while that of DDVP is + dominated by t he fragmentation modes of the (OH30)2P=0 + moiety. Fragmentation §f the (CH30)2P=S characterises the spectrum of (OH30)2"P -Cl while cleavages of the + (C2H50 )2P=S species mark the spectra of parathion and 0-2, 4- di chlorophenyl O, O-diethyl thiophosphate. The 0(, cl eavages of the thioether f unction rather than + cleavages of the (C2H50)2P=S signify the spectrum of carbophenolthion. Tributyl phosphorotrithioite behaves more like an aliphatic hydrocarbon than like the corresponding phosphites. The isopropyl and butyl esters of 2, 4 dichlorophenoxy acetic acid show cleavage and rearrangement ions typical of an ester. In spite of its structural similari ty to pp' - DDT and pp' - DDD, Kalthane has a completely different mass spectral behaviour due to the influence of its hydroxyl function. The thiocarbamate pesticides studied include Eptam and Perbulate. Both are structurally similar but having different alkyl substituents on nitrogen and sulphur. This structurQlsimilarity leads to similar types of (N-C), (O-S) and (S-alkyl cleavages). However, perbulate differs from Eptam in showing a rearrangement ion at mle 161 and in forming an isocyanate ion as the base peak. In Eptam the base peak i s the alkyl ion. The dithiocarbamate, Vegadex, resembles the thiocarbamates in undergoing simple cleavages but it differs from them in having a weak parent ion; in the formation of its base peak and in undergoing a series of rearrangement reactions. The miscellaneous pesticides studied include 1-Naphthalene acetic aCid- methyl ester, Fiperonyl butoxide and Allethrin. The ester i s stable to electron impact and shows only fewer ions. Piper onyl butoxide, a polyether, shows characteristics of an et her, alcohol and aldehyde . Allethrin is regarded as an ester of the type R-C-O-R1 with n R being a substituted cyclopr opane moiety and o Rt, a substituted cyclopentenone mOiety. Accordingly it shows cleavage ions typical of an aliphatic ester and undergoes bond ruptures of the cyclic moieties to give unusual ions. Its base peak is an odd electron ion, quite contrary to expectations.
