Supporting sustainability: the role of Management Control Systems in family SMEs, cap. 1, in AA.VV. (a cura di Cantino V., De Vincentiis P., Racca G.), Risk management: perspectives and open issues- A multi-disciplinary approach
No full textEuropean countries share a concern about business investment: because of the financial
crisis, wealth creation is decreasing and business confidence is weak. At the same time,
social problems like unemployment, underemployment, and poverty are increasing.
In this context, the need to promote economic development consistent with social and environmental
concerns has drastically emerged.
There is an increasing opportunity to assess value creation from a sustainability standpoint
and with a social responsibility approach.
This is what we can define as a “social responsible business model”, based on value creation
for stakeholders. In the new context, also the concept of value creation has to be
changed from value creation for shareholders to value creation for all stakeholders. Value
creation also embed sustainable value (based on a triple bottom line approach), and social
responsibility. Since FFs pursue both economic and social objectives, we can say that there
is a lot of social responsibility in FFs. Family firms (FFs) seems to be likely to adopt the
triple-bottom line paradigm (economic, social, ecological performance) according to their
characteristics: literature affirms that additional feature that distinguishes FFs from NFBs
is their desire to preserve the family’s socioemotional wealth and the pursuit of nonfinancial
outcomes.
In the EU environment, SMEs (especially family SMEs) not only contribute significantly to
the European GDP and employment, but they are also recognized to adopt business models
more sensible to social issues and stakeholder needs.
Although sustainability has been discussed in management control literature to highlight
the need of sustainability control systems (SCSs), little is known about the mode of integration
between SCSs and traditional management control systems in family SMEs.
In order to support SMEs in developing more responsible, innovative and competitive
business models, this paper proposes to study the role of sustainability control systems
(SCSs). In this article we examine the management control literature and family business
literature with the purpose of proposing a sustainable business model. We summarize literature’s orientation, in order to identify the drivers of adoption of SCSs and their role in
the business model. Starting from a summary of the main FFs features, we will discuss the
following research questions:
-What are the interactions between different forms of social responsibility in FFs?
-How can we transfer the family firms’ attitude to social responsibility in a sustainable
business model?
-What are main elements of a sustainable business model that can leverage on family
firms business model?
-What are different tools, mechanisms, solutions needed to adopt and implement a sustainable
business model?
In summation, sustainability and social responsibility challenges are huge and fast growing:
family SMEs can reply to these challenges, supporting positive sustainable development
outcomes, with more responsible, innovative and competitive business model

Distribution: Brazil, Belize (see discussion). Etymology. The specific epithet refers to the host plant, Duranta repens, on which the species has been found in Brazil. Discussion. Peracchius durantae is unlike any other previously described whitefly, as defined in the generic and species descriptions, above. The distribution of this species will be modified by additional collecting in view of the wide distribution of the host plant in the Brazilian territory, and specimens of P. durantae have also been collected from an unknown host in Belize. Moreover, unidentified material from other countries in Central America and the Caribbean appears to belong to this new genus (J. Martin, personal communication; material in Natural History Museum, London, UK).Published as part of Lima, A.

Relating group size and posting activity of an online community of financial investors: Regularities and seasonal patterns
No full textGroup size can potentially affect collective activity and individual propensity to contribute to collective goods. Mancur Olson, in his Logic of Collective Action, argued that individual contribution to a collective good tends to be lower in groups of large size. Today, online communication platforms represent an interesting ground to study such collaborative dynamics under possibly different conditions (e.g., lower costs related to gather and share information). This paper examines the relationship between group size and activity in an online financial forum, where users invest time in sharing news, analysis and comments with other investors. We looked at about 24 million messages shared in more than ten years in the finanzaonline.com online forum. We found that the relationship between the number of active users and the number of posts shared by those users is of the power type (with exponent α>1) and is subject to periodic fluctuations, mostly driven by hour-of-the-day and day-of-the-week effects. The daily patterns of the exponent showed a divergence between working week and weekend days. In general, the exponent was lower before noon, where investors are typically interested in market news, higher in the late afternoon, where markets are closing and investors need better understanding of the situation. Further research is needed, especially at the micro level, to dissect the mechanisms behind these regularities
Peracchius durantae Lima & Racca-Filho, 2005, sp. n.
No full textType species <i>Peracchius durantae</i> sp. n. <p> <b>Diagnosis</b>: Puparium medium in size, narrowly elongate spindle­shaped, acute posteriorly, acute­or­indented anteriorly; always with a pair of acute and stout subapical setae at each end; anterior and posterior marginal setae considerable distances away from puparial apices, but unusually long; margin irregularly crenulate; wax secretions absent; submargin not separated from dorsal disc by a fold or suture; margin modified at thoracic and caudal tracheal openings (from slightly indented to a <i>Dialeurodes</i> ­like pore); caudal furrow distinct; operculum obscuring lingula, filling vasiform orifice (but detail of lingula often visible through operculum); with normal pair of 8th abdominal setae close to vasiform orifice, and a second 8th abdominal pair posterior to vasiform orifice; typically with a pair of setae on each of abdominal segments I, II­VII, pro­, meso­and metathorax most or all of these capitate; cephalic region with submedian setal pair (the normal “cephalic setae”) of variable size/shape, and at least two other pairs that are usually capitate the positions of all the capitate setae are variable between species sometimes in outer submargin; transverse moulting sutures reaching, or almost reaching puparial margin; many segments usually with tubercles in submedian zone, either along median line or bordering submedian zone (as in <i>P. durantae</i>, Figs 1 A, 2A); ventral tracheal folds marked, sometimes only subtly; legs well separated from each other.</p> <p> <b>Etymology</b>: The generic name is in tribute to Dr. Adriano Lucio Peracchi, from Universidade Federal Rural do Rio de Janeiro, for his contributions to our knowledge of Brazilian whiteflies.</p> <p> <b>Affinities</b>: The new genus appears to be most closely allied to <i>Dialeurodes</i> <b>­</b> group as defined by Jensen (2001), with relatively abundant dorsal setae, tracheal notches, pores at margin, tendency to have an ornate lingula (when it can be discerned), and ventral tracheal folds. However, the combination of elongate spindle­shaped puparia, extremely stout caudal and anterior submarginal setae, capitate dorsal disc setae and the chaetotaxy do combine to indicate a distinct generic assemblage. The new genus superficially resembles <i>Agrostaleyrodes</i> Ko, 2001, differing from it in the presence of abdominal tubercles instead of depressions, more extensive chaetotaxy, tracheal and caudal folds evident, the transverse moulting suture reaching the margin and in the absence of longitudinal ridges on dorsum. <i>Agrostaleyrodes</i> is a grass­feeding genus, and grass­feeding whiteflies rarely also colonise dicotyledonous hosts.</p>Published as part of <i>Lima, A.

Osteopathic Manipulative Treatment Improves Heart Surgery Outcomes: A Randomized Controlled Trial
No full textBackground. Controlling sternal pain after heart surgery is important to reduce the risk of postoperative complications, but pain is often undertreated because of contraindications and side effects of analgesic drugs. Recently, osteopathic manipulative treatment (OMT) was demonstrated to reduce pain in different clinical contexts, suggesting its potential utility after cardiac surgery. The aim of this open-label, controlled study is to assess whether OMT contributes to sternal pain relief and improves postoperative outcomes. Methods. Eighty post-sternotomy adult inpatients were randomly allocated one to one to receive a standardized cardiorespiratory rehabilitation program alone (control group) or combined with OMT. Pain intensity and respiratory functional capacity were quantified by the Visual Analogue Scale score and by a standardized breathing test, at the start and end of rehabilitation. Results. At the start of rehabilitation, the control group and the OMT group had similar Visual Analogue Scale median scores (controls 4, interquartile range [IQR]: 2 to 5; OMT 4, IQR: 3 to 5; p = not significant) and mean inspiratory volumes (controls 825 +/- 381 mL; OMT 744 +/- 291 mL; p [not significant). At the end of rehabilitation, the OMT group had a lower Visual Analogue Scale median score (controls 3, IQR: 2 to 4; OMT 1, IQR: 1 to 2; p < 0.01) and higher mean inspiratory volume (controls 1,400 +/- 588 mL; OMT 1,781 +/- 633 mL; p < 0.01). The analgesic drug intake was similar in the two groups. The hospitalization was shorter in the OMT group than in the control group (19.1 +/- 4.8 versus 21.7 +/- 6.3 days; p < 0.05). Conclusions. The combination of standard care with OMT is effective in inducing pain relief and functional recovery, and significantly improves the management of patients after heart surgery with sternotomy.
