Psychological Sense of Community: A New Construct for the Field of Management

This article introduces a new construct to the field of management called Psychological Sense of Community (PSOC). This is important because management scholars are calling for the creation of communities in organizations in an environment that lacks appropriate construct development. The aims of this article are threefold: (a) develop a working definition of PSOC via a review of the extant literature on PSOC from other disciplines with the goal of translating it into the domain of management, (b) synthesize findings from parallel literatures on the outcomes of PSOC with an eye toward exploring the relevance of such outcomes in management contexts, and (c) assess the value of PSOC as it relates to its uniqueness in relation to other prominent management constructs and its scope of applicability in a variety of management inquiry areas.

Muslim Literature in Serbo-Croat in Relation to the Serbian and Croatian Literatures

Mr. Tutnjevic set out to define the position of the Muslim community within the overall framework of literature in Serbo-Croat, particularly in terms of its relation to the Serbian and Croatian Literatures, on the basis of an extensive comparative study of primary and secondary sources relating to the most important Muslim writers in Serbo-Croat. Carried out against the background of an unprecedented civil war between these national groups, his research focused rather on the encounters between them on the historical and literary stages. He concludes that the Muslim national community was established and developed on a foundation of Slavic self-consciousness and oriental influences. The constantly changing relative weights of the influence of these two factors on the community shaped the specific nature of its literature as well as its place in the cultural environment of its neighbouring national communities, and Muslim literary traditions are inseparably linked with the total literature in Serbo-Croat. A real Muslim literature first emerged at the end of the nineteenth century and virtually all authors writing about this at the time emphasised its educational character and its importance for the process of national identification. At the same time there were visible results of the self-awareness process in which Muslim authors affiliated with Serbian or Croatian literary tradition, sometimes even substituting one with another. During the period between the two world wars Muslim literature reached maturity and while Muslim authors generally focused on their national milieu in terms of subject matter, their forms of expression and their understanding of the function of literature showed the same preoccupation as other Yugoslav authors of the period. When the ideological and class-related concept of society replaced the national character of literature after 1945, Muslim writers found themselves in the same position as writers from other ethnic groups. As in earlier times, writers sought to present themselves to as wide a market as possible and would provide grounds for consideration as Serbian or Croatian writers, sometimes even explicitly presenting themselves as such. Most of the writers of this period are described at times as Yugoslav, at others as Bosnian-Herzegovina, and at still others as Serbian, Croatian or Muslim. Mr. Tutnjevic quotes, for example, the case of Camil Sijaric, a Muslim from Sandzak who also wrote in Sarajevo and falls within the boundaries of Bosnian-Herzegovnian literature, but is also described as a Muslim, Montenegrin and Serbian writer, together with a number of other such examples. An understanding of this process provides the basis for a completely new perception of the intertwining of Serbian, Croatian and Muslim literary traditions, without the earlier visible prejudice on all three sides.

New Prosperity for Rural Regions

The project deals with problems of marginal rural regions in the period of transformation in Slovenia and the Czech Republic. The course of the transformation, its impact, related border problems and environmental aspects were studied in seven model regions of the two countries, using geographical, cartographic, sociological, historical and remote-sensing methods. The opinions of both the local populations and the local authorities were also taken into account. The most important problems observed included the deepening of marginality, the worsening situation in the labour market, structural demographic degradation of the most marginal settlements and a lack of development programmes. In the Czech Republic the state had no effective regional policy up to the time of the research. Possibilities for future prosperity include exploitation of human and other local resources, the elaboration of local and regional programmes capable of gaining financial support and the utilisation of tranquility and the positive environmental situation. It is the local people who usually represent the main wealth of marginal regions and care for them is the task of the local authorities.

Proposing new approaches for dating young volcanic eruptions by luminescence methods

The application of luminescence dating to young volcanic sediments has been first investigated over three decades ago, but it was only with the technical innovations of the last decade that such analyses became viable. While current analytical procedures show promise for dating late Quaternary volcanic events, most efforts have been aimed at unconsolidated volcanic tephra. Investigations into direct dating of lava flows or of non-heated volcanoclastics like phreatic explosion layers, however, remain scarce. These volcanic deposits are of common occurrence and represent important chrono- and volcanostratigraphic markers. Their age determination is therefore of great importance in volcanologic, tectonic, geomorphological and climate studies. In this article, we propose the use of phreatic explosion deposits and xenolithic inclusions in lava flows as target materials for luminescence dating applications. The main focus is on the crucial criterion whether it is probable that such materials experience complete luminescence signal resetting during the volcanic event to be dated. This is argued based on the findings from existing literature, model calculations and laboratory tests.

Clinicopathologic correlations of silent corticotroph adenomas of the pituitary: report of four cases and literature review

Silent corticotroph adenomas (SCA) are rare pituitary tumors with histologic hallmarks of corticotroph differentiation, including ACTH immunoreactivity, but lacking clinical evidence of Cushing's syndrome. We report on four female patients, aged 19-66 years, each presenting with a nonfunctional macroadenoma. Leading symptoms were headache in two cases and visual field deficits in one. One patient was incidentally diagnosed while undergoing cranial MRI for an unrelated condition. Three patients had marked obesity; none of them presented constitutional signs of Cushing's syndrome. Serum cortisol levels were moderately elevated in the two patients systematically tested in this respect. Marginal to moderate hyperprolactinemia was present in two cases. Two patients also were shown to be deficient in either gonadotroph or thyrotroph axis, while a third had a combined insufficiency of both gonadotroph and thyrotroph axis. MRI scans revealed intratumoral hemorrhage and/or cystic change in three cases, as well as tumor-related occlusive hydrocephalus in one. The latter patient was biopsied only, while the remaining underwent gross total resection. Histologically, all four lesions were diagnosed as SCA subtype I displaying intense immunoreactivity for ACTH. In three tumors, scattered cells coexpressed PRL as well. In addition, Crooke's hyaline change was noted in a significant number of tumor cells and in residual non-neoplastic corticotrophs in one case each. With MIB-1 labeling indices of 1-3%, none of the tumors qualified as atypical adenoma. We conclude that SCAs are more likely to be discovered as expansile tumors, whose advanced local space-occupying character at surgery rather than an inherently aggressive growth potential may negatively influence the clinical outcome. Subtle morphologic evidence of corticotroph suppression in residual pituitary adjacent to tumor lends further support to literature data indicating minimal or intermittent functional activity in this tumor type.

Marginal Structural Models for Partial Exposure Regimes

Intensive care unit (ICU) patients are ell known to be highly susceptible for nosocomial (i.e. hospital-acquired) infections due to their poor health and many invasive therapeutic treatments. The effects of acquiring such infections in ICU on mortality are however ill understood. Our goal is to quantify these effects using data from the National Surveillance Study of Nosocomial Infections in Intensive Care Units (Belgium). This is a challenging problem because of the presence of time-dependent confounders (such as exposure to mechanical ventilation)which lie on the causal path from infection to mortality. Standard statistical analyses may be severely misleading in such settings and have shown contradicting results. While inverse probability weighting for marginal structural models can be used to accommodate time-dependent confounders, inference for the effect of ?ICU acquired infections on mortality under such models is further complicated (a) by the fact that marginal structural models infer the effect of acquiring infection on a given, fixed day ?in ICU?, which is not well defined when ICU discharge comes prior to that day; (b) by informative censoring of the survival time due to hospital discharge; and (c) by the instability of the inverse weighting estimation procedure. We accommodate these problems by developing inference under a new class of marginal structural models which describe the hazard of death for patients if, possibly contrary to fact, they stayed in the ICU for at least a given number of days s and acquired infection or not on that day. Using these models we estimate that, if patients stayed in the ICU for at least s days, the effect of acquiring infection on day s would be to multiply the subsequent hazard of death by 2.74 (95 per cent conservative CI 1.48; 5.09).

Neonatal macrocephaly: cerebral primitive neuroectodermal tumor or neuroblastoma as an infrequent cause--a case report and review of the literature

We report a male term newborn presenting with a congenital macrocephaly 3.5 standard deviations above the median, with a wide and tense anterior fontanel, splayed calvarial sutures, and muscular hypotonia. Antenatal head circumferences were repeatedly below the median. A postnatal head ultrasound showed a large right intracerebral mass with right lateral ventricle compression, right temporal horn dilation, and right frontal horn enlargement with lateral displacement. Additional imaging by computed tomography scan and magnetic resonance imaging was performed. A decompression was performed and histology, immunohistochemistry, and molecular biology supported the diagnosis of a primitive neuroectodermal tumor. A MYCN gene amplification assay remained negative. The incidence of neonatal brain tumors is between 1.4 and 4.1/100,000 live births. Their most common presentation is macrocephaly, hydrocephalus, stillbirth, or diagnosis by pre- or postnatal imaging. Although hydrocephaly and intra- or extracranial hemorrhage are the most frequent causes of congenital macrocephaly, this should be initially investigated by head ultrasound. A suspected malignancy will be confirmed by histopathology, immunohistochemistry, and molecular biology.

[Pyelonephritis treatment in children in 2007: current literature review]

Four studies, including two being published as an abstract, have recently demonstrated the feasibility of oral treatment of pyelonephritis in children, with no increased risk of treatment failure, early urinary tract re-infection, or renal scars. To do so, the pediatrician must ensure that: (1) the patient does not appear toxic, has no vomiting; (2) there is no known severe obstructive or refluxing uropathy and (3) parents are deemed to be adherent to the treatment. If these criteria are fulfilled, the pediatrician can start an oral treatment with a 3rd generation cephalosporine for 10 to 14 days. Ambulatory follow-up is crucial, and persistance of fever after 3 days is a reason for a new outpatient visit, additional or supplementary imaging studies (renal ultrasonography) and eventually a switch to intravenous treatment.

Noncompliance in organ transplant recipients: a literature review

The consequences of failing to comply to doctor's instructions can be damaging and devastating for the individual patient and their family. Noncompliance also leads to waste, as it reduces the potential benefits of therapy, and to the extra cost of treating avoidable consequent morbidity. Life-long immunosuppression is a prerequisite for good graft function, and noncompliance is often associated with late acute rejection episodes, graft loss, and death. It might be assumed that transplant patients constitute a highly motivated group, and that compliance would be high. Unfortunately, this is not the case: overall noncompliance rates vary from 20 to 50%. This overview includes literature on heart, liver, and kidney transplants in adult and pediatric transplant patients. Compliance behavior after transplantation, noncompliance and its relationship to organ loss and death, retransplantation outcome after graft loss due to noncompliance, and reasons for postoperative noncompliance will be addressed.

Late-onset posttraumatic septal hematoma and abscess formation in a six-year-old Tamil girl--case report and literature review

Nasal septal hematoma with abscess (NSHA) is an uncommon complication of trauma and studies on children are especially rare. We discuss the case of a 6-year-old girl, who was initially evaluated independently by three doctors for minor nasal trauma but had to be re-hospitalized 6 days later with NSHA. Although septal hematoma had initially been excluded (5, 7 and 24 hours after trauma), a secondary accumulation of blood seems to have occured. Delayed hematoma formation has been described in the orbit as a result of possible venous injuries after endoscopic sinus surgery. However, such an observation is new for septal hematoma in children. Thus, we recommend re-evaluation for septal hematoma 48h to 72h after paediatric nasal trauma. Such a scheduled re-examination offers a chance to treat delayed subperichondral hematoma on time before almost inevitable superinfection leads to abscess formation and destruction of the nasal infrastructure. We suggest that parents should be vigilant for delayed nasal obstruction as possible herald of hematoma accumulation within the first week.

Building the New Society in the Shell of the Old: Finnish-Canadian Hall Socialism and the Canadian Industrial Unionist Support League

The literature on Finnish immigrant working-class movements in North America frequently makes reference to the phenomenon of "hall socialism," so-called because of the central position that the socialist or labor hall occupied in the political, associational, and cultural life of many Finnish communities throughout the twentieth-century. In the 1930s, over 80 such Finnish halls were spread across Canada, and many people associated with these halls vigorously supported the mission of organized labor. This paper will examine the history, ideas, and practices of the Industrial Workers of the World-influenced Canadan Teollisuusunionistien Kannatus Liitto (CTKL; Canadian Industrial Unionist Support League), and its connections to Finnish Canadian hall socialism. The paper will consider the role of the CTKL in supporting workers' struggles, the significance of the hall as a part of the infrastructural bedrock that sustained this support, and the broader interaction between social and radical organizing commitments.

Free anteromedial thigh flap: clinical application and review of literature

The anteromedial thigh (AMT) flap is reviewed in terms of its vascular anatomy and previous clinical reports in the literature. Our own series of 5 patients treated with this flap for defects in the head and neck region and lower extremity is presented. Although several authors controversially discussed vasculature, we constantly found the pedicle as an emerging septocutaneous perforator at a point where the medial border of the rectus femoris muscle is crossed by the sartorius muscle. In all 5 patients, the AMT flap provided stable coverage with no flap loss. Based on our findings, we conclude that the anteromedial thigh flap offers all the advantages of fasciocutaneous flaps. Therefore, we recommend this flap as an alternative for defects requiring coverages of thin to moderate skin thickness. However, it should be remembered that variations in vascular anatomy are possible.

The impact of new technologies on distance learning students

This is a European Commission Leonardo da Vinci Reference Material project on the impact of new technology on distance learning students. It is known that all the Ministries of Education of the 27 European Union countries pay millions of Euros annually in the provision of educational technology for their schools, colleges and universities. A review of the literature of the impact of technology, however, showed that the research in this field was unacceptably fragile. What research there was focused on the impact of technology on children in American schools. The project set out, therefore, to measure the impact of technology on adult education, lifelong learning and distance education, with a particular focus on adult distance learning.
