Ceramonematidae (Nematoda) de fonds vaseux profonds de Méditerranée

Representatives of the family Ceramonematidae (Cobb, 1933) were found untill now mainly in shallow sandy bottoms. The five species mentioned hereunder, from which four are new ones were recovered from mud in the « Golfe du Lion » (Mediterrranean) at a depth of 310-580 m. A male specimen of Ceramonema chitwoodi De Coninck, 1942 is described. Two new species are added to the genus Metadasynemella: M. falciphala and M. cassidiniensis. Pselionema deconincki sp.n. is the first species of this genus with vacuolisations in the cuticle. Pselionema minutum sp.n. is a very small species

Ideal versus corrected body weight for dosage of sugammadex in morbidly obese patients

Summary To date, the dosing of sugammadex is based on real body weight without taking fat content into account. We compared the reversal of profound rocuronium-induced neuromuscular blockade in morbidly obese patients using doses of sugammadex based on four different weight corrections. One hundred morbidly obese patients, scheduled for laparoscopic bariatric surgery under propofolsufentanil anaesthesia, were randomly assigned four groups: ideal body weight; ideal body weight + 20%; ideal body weight + 40%; and real body weight. Patients received sugammadex 2 mg.k

Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome: a case report

<p>Abstract</p> <p>Introduction</p> <p>We report the case of an unusual association of Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome. This association has never previously been reported in the medical literature.</p> <p>Case presentation</p> <p>A nine-year-old Indian girl was referred to our hospital for growth retardation, mental retardation, lax joints, generalized hypertrichosis, and hypoplastic fifth fingernails and toenails. A thorough medical examination and evaluation revealed she had phenotypic features of Coffin-Siris syndrome, with Mayer-Rokitansky-Küster-Hauser syndrome on radiological evaluation. The karyotype of our patient was normal.</p> <p>Conclusion</p> <p>In an unexplained case of mental retardation with facies suggestive of Coffin-Siris syndrome, association with Mayer-Rokitansky-Küster-Hauser syndrome should be considered and the patient should be evaluated for the same. Both of these syndromes may have a common pathogenesis, as yet unknown. This case report has broad implications, as similar cases in future may give insights into the pathogenesis of both these syndromes.</p

Resist or Comply:The Power Dynamics of Organizational Routines during Mergers

The role of power and agency in the development of organizational routines is under-theorized. In this paper, we draw on an in-depth qualitative case study of a merger between two academic institutions, a college of art and a university, and examine the diverging responses of two organizational routines (admissions and budgeting) during the course of the merger to understand how power dynamics contribute to resistance/compliance of routines. Our findings suggest that the differences in routines’ responses to a merger initiative can be explained by applying Bourdieu's theory of practice and by employing the concepts of field and symbolic capital to unpack power relations in the context of organizational routines, and to disclose why some routine participants can exercise their agency while others cannot. We find that (a) the field within which a routine operates and (b) the actors’ symbolic capital and position-taking during change implementation shape routines’ responses to organizational change initiatives

What, When and Who:Manager Involvement in Predicting Employee Resistance to Acquisition Integration

Applying sensemaking research to acquisition integration, we outline factors that influence employee resistance to acquisitions. While integration is widely viewed as important to acquisition outcomes, there is limited systematic study of how employees react to the integration process. Using survey data from Chinese acquirers and applying partial least squares structural equation modeling, we examine what changes with human and task integration with the speed of when changes are made to explore relationships with employee resistance. Consistent with a temporal perspective of acquisition processes and sensemaking we find slower task integration may mitigate employee resistance to acquisition integration. However, employee resistance to the speed that changes are made likely varies for who is involved, suggesting different roles for top and middle managers. Specifically, middle management involvement with slow human integration and top management involvement with fast task integration reduces employee resistance following an acquisition

Using rival effects to identify synergies and improve merger typologies

"The strategic management literature has found it difficult to differentiate between collusive and efficiency-based synergies in horizontal merger activity. We propose a schematic to classify mergers that yields more information on merger types and merger effects, and that can, moreover, distinguish between mergers characterized largely by collusion-based synergies and mergers characterized largely by efficiency-based synergies. Crucial to the proposed measurement procedure is that it encompasses the impact of merger events not only on merging firms - as is custom - but also on non-merging competitor firms (the rivals). Employing the event-study methodology with stock-market data on samples of large horizontal mergers drawn from the US and UK (an Anglo-Saxon sub-sample) and from the European continent, we demonstrate how the proposed schematic can better clarify the nature of merger activity." (author's abstract)"Die Literatur über strategisches Management hatte bisher Schwierigkeiten, zwischen wettbewerbsschädlichen und Effizienz steigenden Synergien bei horizontalen Zusammenschlüssen zu differenzieren. Wir schlagen einen konzeptionellen Rahmen vor, um Fusionen zu klassifizieren, welcher mehr Informationen sowohl über die Fusionstypologie als auch über die Wirkung von Zusammenschlüssen entschlüsselt und welcher eine klare Abgrenzung zwischen wettbewerbsschädlichen und wettbewerbsfreundlichen Fusionen erlaubt. Fundamental für diesen konzeptionellen Rahmen ist, dass er nicht nur die Wirkung der Fusion auf die fusionierenden Unternehmen (was typisch in der Literatur ist) umfasst, sondern auch ihre Wirkung auf die Rentabilität der Wettbewerber. Wir wenden eine Ereignisstudienmethode mit Aktiendaten an, um unsere Kategorisierung empirisch umzusetzen. Im Vergleich einer Stichprobe von Fusionen in der angelsächsischen Welt (US und Großbritannien) mit Fusionen zwischen kontinentaleuropäischen Firmen zeigen wir, wie unsere Methodologie hilfreich sein kann, die Art der Fusionsaktivitäten zu identifizieren."

The moderating role of transformational leadership on HR practices in M&A integration

Scant research exists examining the effect of HRM practices on employee behavior in M&A integration and the role that leaders play within this. This paper develops a conceptual framework that focuses on the moderating role of transformational leadership on the achievement of human integration and organizational identification in M&A integration. We argue that communication, employee involvement, teamwork, and training and development have a positive effect on employee behavior and their identification with the newly formed organization. Moreover, we argue that transformational leadership behaviors will moderate the implementation of HRM practices in M&As, leading to positive employee behavior and employee identification in the new organization. We suggest that further research is necessary to test propositions of the present study in order to achieve finer-grained understanding of the role of transformational leadership on the achievement of human integration and organizational identification in M&A integration

Organisational Resilience in Acquisition Integration—Organisational Antecedents and Contingency Effects of Flexibility and Redundancy

Resilience has received increasing attention in organisational research; however, it has remained understudied in the context of acquisitions. This is surprising given acquisitions involve challenging events that would benefit from a consideration of organisational resilience. We outline how flexibility and redundancy, as dimensions of organisational resilience, influence acquisition outcomes. We find flexibility can lower negative impacts of competitor retaliation and employee resistance during acquisition integration, but this depends on a decentralised approach to managing integration. Additionally, it appears developing organisational resilience depends on acquisition experience

Randomised controlled trial of cervical radiofrequency lesions as a treatment for cervicogenic headache [ISRCTN07444684]

BACKGROUND: Cervicogenic headache (CEH) is a unilateral headache localised in the neck or occipital region, projecting to the frontal and temporal regions. Since the pathogenesis of this syndrome appears to have an anatomical basis in the cervical region, several surgical procedures aimed at reducing the nociceptive input on the cervical level, have been tested. We developed a sequence of various cervical radiofrequency neurotomies (facet joint denervations eventually followed by upper dorsal root ganglion neurotomies) that proved successful in a prospective pilot trial with 15 CEH patients. To further evaluate this sequential treatment program we conducted a randomised controlled trial METHODS: 30 patients with cervicogenic headache according to the Sjaastad diagnostic criteria, were randomised. 15 patients received a sequence of radiofrequency treatments (cervical facet joint denervation, followed by cervical dorsal root ganglion lesions when necessary), and the other 15 patients underwent local injections with steroid and anaesthetic at the greater occipital nerve, followed by transcutaneous electrical nerve stimulation (TENS) when necessary. Visual analogue scores for pain, global perceived effects scores, quality of life scores were assessed at 8, 16, 24 and 48 weeks. Patients also kept a headache diary. RESULTS: There were no statistically significant differences between the two treatment groups at any time point in the trial. CONCLUSION: We did not find evidence that radiofrequency treatment of cervical facet joints and upper dorsal root ganglions is a better treatment than the infiltration of the greater occipital nerve, followed by TENS for patients fulfilling the clinical criteria of cervicogenic headache
