Job- and organization-based psychological ownership: relationship and outcomes
Authors: Peng He , Pierce Jon 
Published: February 2015

Purpose– The purpose of this paper is to investigate the relationship between job- and organization-based psychological ownership. In addition, the authors explored the emergence and outcomes of psychological ownership in Chinese context.Design/methodology/approach– Time-lagged survey data from 158 Chinese participants were used to test several hypothesized relationships employing partial least square techniques.Findings– Job-based psychological ownership appeared to mediate the relationship between experienced job control and organization-based psychological ownership. In addition, a statistically significant relationship between job-based psychological ownership and job satisfaction, organizational citizenship behaviors and turnover intentions, and a statistically significant relationship between organization-based psychological ownership and job satisfaction were observed. A negative relationship between organization-based psychological ownership and knowledge withholding was also observed.Practical implications– Managers who want to enhance employees’ job- and ultimately organization-based psychological ownership should empower their employees by enabling them to exert control over their work.Originality/value– This paper examined how organization-based psychological ownership emerges from control over work via job-based psychological ownership. The authors also investigated the impact of psychological ownership in Chinese context.

Published: February 2015

Purpose– The purpose of this paper is to examine the relationship of personal motivational goals and the corresponding occupational characteristics of volunteer, work-related activities in retirement with life and work satisfaction.Design/methodology/approach– Fully retired individuals working for a non-profit organization in their former professional career field on a non-paid basis were surveyed using an online survey (n=661) to assess their motivational goals, the occupational characteristics of their projects, and satisfaction with life and work.Findings– Results suggested that post-retirement volunteer workers differentiated between perceived life and work satisfaction. The motives of achievement, appreciation, autonomy, contact, and generativity significantly directly affected life satisfaction and indirectly affected work satisfaction. Occupational characteristics assessing achievement, appreciation, autonomy, contact, and generativity had direct effects on work satisfaction but not on life satisfaction except for occupational autonomy.Research limitations/implications– The study was cross-sectional and based on self-report data of highly educated German retirees working in volunteer professional positions, thus potentially limiting the generalizability of findings.Practical implications– Organizations should enable post-retirement volunteer workers to meet their motivation goals by designing work opportunities to fulfill the motivational goals of achievement, appreciation, autonomy, contact, and generativity.Social implications– Post-retirement activities possess the potential to help solve societal problems by countering the shortage of specialists and managers at the same time that the burden on social security systems is reduced.Originality/value– The paper presents evidence that different personal motivational goals and occupational characteristics are important in post-retirement activities. The findings imply that work designs created for post-retirement activities should provide a variety of occupational characteristics, such as occupational achievement and appreciation.

Ecologists, evolutionary biologists and biomedical researchers are investing great effort in understanding the impact maternal stress may have on offspring phenotypes. Bian et al. advance this field by providing evidence that density‐induced maternal stress programs offspring phenotypes, resulting in direct consequences on their fitness and population dynamics, but doing so in a context‐dependent manner. They suggest that intrinsic state alterations induced by maternal stress may be one ecological factor generating delayed density‐dependent effects. This research highlights the connection between maternal stress and population dynamics, and the importance of understanding the adaptive potential of such effects in a context‐dependent manner.
Population size‐structure‐dependent fitness and ecosystem consequences in Trinidadian guppies

Published: February 2015

SummaryDecades of theory and recent empirical results have shown that evolutionary, population, community and ecosystem properties are the result of feedbacks between ecological and evolutionary processes. The vast majority of theory and empirical research on these eco‐evolutionary feedbacks has focused on interactions among population size and mean traits of populations.However, numbers and mean traits represent only a fraction of the possible feedback dimensions. Populations of many organisms consist of different size classes that differ in their impact on the environment and each other. Moreover, rarely do we know the map of ecological pathways through which changes in numbers or size structure cause evolutionary change. The goal of this study was to test the role of size structure in eco‐evolutionary feedbacks of Trinidadian guppies and to begin to build an eco‐evolutionary map along this unexplored dimension.We used a factorial experiment in mesocosms wherein we crossed high‐ and low‐predation guppy phenotypes with population size structure. We tested the ability of changes in size structure to generate selection on the demographic rates of guppies using an integral projection model (IPM). To understand how fitness differences among high‐ and low‐predation phenotypes may be generated, we measured the response of the biomass of lower trophic levels and nutrient cycling to the different phenotype and size structure treatments.We found a significant interaction between guppy phenotype and the size structure treatments for absolute fitness. Size structure had a very large effect on invertebrate biomass in the mesocosms, but there was little or no effect of the phenotype. The effect of size structure on algal biomass depended on guppy phenotype, with no difference in algal biomass in populations with more, smaller guppies, but a large decrease in algal biomass in mesocosms with phenotypes adapted to low‐predation risk.These results indicate an important role for size structure partially driving eco‐evolutionary feedbacks in guppies. The changes in the ecosystem suggest that the absence of a steep decline in guppy fitness of the low‐predation risk populations is likely due to higher consumption of algae when invertebrates are comparatively rare. Overall, these results demonstrate size structure as a possible dimension through which eco‐evolutionary feedbacks may occur in natural populations.
Biological Flora of the British Isles:Crambe maritima
Authors: Sanyal Anushree , Decocq Guillaume 
Published: February 2015

SummaryThis account presents information on all aspects of the biology ofCrambe maritimaL. (Sea‐kale;Crambe ponticaStev. ex Rupr) that are relevant to understand its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation.Crambe maritimais found predominantly on southern and western coasts of Britain but also in Scotland, Ireland and elsewhere. It occurs primarily on neutral or slightly alkaline soils on shingle and sand beaches above the drift line, out of reach of average high tides. Equinoctial tides or storms can increase soil salinity, requiring it to be salt tolerant.Crambe maritimais a rosette plant with a fleshy taproot, which is the main perennating organ with a capacity for vegetative propagation. Flowering can take 5–8 years when grown from seeds. Reproduction is predominantly by seeds. Root and stem cuttings can be used for vegetative propagation. In winter, each branch ends at ground level in a leafless crimson bud, and in spring, it produces a succession of cabbage‐like leaves just above ground level, the first being purple and successive leaves becoming greener.Crambe maritimaproduces weakly protogynous hermaphrodite flowers. Self‐ and cross‐pollination occurs. Pollination is by insects, flies and bees. The plants usually produce 1000–10 000 seeds per year.In Britain,Crambe maritimahas been reported to have declined in certain areas but increased in other areas and currently does not have rare or scarce status. There has been an expansion in range in Ireland since the 1960s as it has been recorded at new sites, and while the species has disappeared from some sites in France, it has also been identified in several new sites.
Unusual Suicide in Italy: Criminological and Medico‐Legal Observations—A Proposed Definition of “Atypical Suicide” Suitable for International Application
Authors: Massaro Luca 
Published: February 2015

AbstractThis work is the result of a kind ofcategorizationof suicidal conduct based on an empirical–phenomenological approach, with integrated assessment of certain criteria, such as the dynamics, correlation of types of injury and how they were produced, evidence gathered during official inspectionsin loco, and case history findings about “suicide.” Thiscategorizationis an attempt to provide a nosographic definition ofatypical suicide, that is, cases in which the parameters of “typical” suicide are missing. Case studies are described, taken from a systematic exploration mainly of the Italian specialized literature of the 20th century, supplemented by earlier references when deemed significant. In‐depth analysis ofatypical suicidecan supply additional interpretations of the problem of differential diagnosis of suicide, homicide, and accidental death, that is, the realpunctum dolensin overall medico‐legal determination of the cause of death in scenarios in which death cannot be definitely traced to a deliberate act.
Facial Approximation—From Facial Reconstruction Synonym to Face Prediction Paradigm
Authors: Stephan Carl N. 
Published: February 2015

AbstractFacial approximation was first proposed as a synonym for facial reconstruction in 1987 due to dissatisfaction with the connotations the latter label held. Since its debut, facial approximation's identity has morphed as anomalies in face prediction have accumulated. Now underpinned by differences in what problems are thought to count as legitimate, facial approximation can no longer be considered a synonym for, or subclass of, facial reconstruction. Instead, two competing paradigms of face prediction have emerged, namely: facial approximation and facial reconstruction. This paper shines a Kuhnian lens across the discipline of face prediction to comprehensively review these developments and outlines the distinguishing features between the two paradigms.
Systematic review: Whipple's disease (Tropheryma whipplei infection) and its unmasking by tumour necrosis factor inhibitors
Authors: Marth T. 
Published: February 2015

SummaryBackgroundThe classical form of Whipple's disease (WD), clinically characterised by arthropathy, diarrhoea and weight loss, is rare. Recently, other more frequent forms of Tropheryma whipplei infection have been recognised. The clinical spectrum includes an acute, self‐limiting disease in children, localised forms affecting cardiac valves or the central nervous system without intestinal symptoms, and asymptomatic carriage of T. whipplei which is found in around 4% of Europeans. Genomic analysis has shown that T. whipplei represents a host‐dependent or opportunistic bacterium. It has been reported that the clinical course of T. whipplei infection may be influenced by medical immunosuppression.AimTo identify associations between immunomodulatory treatment and the clinical course of T. whipplei infection.MethodsA PubMed literature search was performed and 19 studies reporting on immunosuppression, particularly therapy with tumour necrosis factor inhibitors (TNFI) prior to the diagnosis in 41 patients with Whipple?s disease, were evaluated.ResultsAs arthritis may precede the diagnosis of WD by many years, a relevant percentage (up to 50% in some reports) of patients are treated with immunomodulatory drugs or with TNFI. Many publications report on a complicated Whipple?s disease course or T. whipplei endocarditis following medical immunosuppression, particularly after TNFI. Standard diagnostic tests such as periodic acid–Schiff stain used to diagnose Whipple?s disease often fail in patients who are pre‐treated by TNFI.ConclusionsIn cases of doubt, Whipple?s disease should be excluded before therapy with TNFI. The fact that immunosuppressive therapy contributes to the progression of T. whipplei infection expands our pathogenetic view of this clinical entity.
The shift from “e‐learning” to “learning”: Invisible technology and the dropping of the “e”
Authors: Paiva João , Morais Carla , Costa Luiza , Pinheiro Ana 
Published: February 2015

AbstractDue to the generalization of electronically supported activities, we anticipate that, in the near future, the letter “e” in “e‐learning,” indicating the use of electronic media and information and communication technologies in education, will be dropped and that “e‐learning” will be referred to as simply “learning.” This paper presents an attempt at understanding the causes of the name shift and at predicting its consequences. We offer a constructive reflection on how e‐learning has been looked upon and on what we foresee will happen in the future, drawing briefly on several areas of knowledge and on the experience of the authors as educators at university, teacher training and high school levels. Our effort has also resulted in greater awareness of the importance of social tools and of the relevance of the human factor in the learning process.
Like parent, like child? Development of prejudice and tolerance towards immigrants
Authors: Miklikowska Marta 
Published: February 2015

Although intergroup attitudes are assumed to develop due to the influence of parents, there is no longitudinal evidence supporting this claim. In addition, research on socialization of intergroup attitudes has omitted possible effects of adolescents on their parents. We also know little about the conditions under which intergroup attitudes are transmitted. This two‐wave, 2 years apart, study of adolescents (N = 507) and their parents examined the relations between parents and adolescents' prejudice and tolerance from a longitudinal perspective. The study tested whether parental prejudice and tolerance would predict over‐time changes in adolescents' attitudes and whether adolescents' prejudice and tolerance would elicit changes in parental attitudes. Additionally, it explored whether some of the effects would depend on perceived parental support. Results showed significant bidirectional influences between parents and adolescents' attitudes. In addition, adolescents who perceived their parents as supportive showed higher parent–adolescent correspondence in prejudice than youth with low parental support. These findings show that intergroup attitudes develop as a result of mutual influences between parents and adolescents. Hence, the unidirectional transmission model and previous research findings should be revisited. The results also suggest that parents' prejudice influence adolescents' attitudes to the extent that youth perceive their parents as supportive.

Published: February 2015

Hepatocellular carcinoma is the primary malignancy of the liver and is the third leading cause of cancer‐related death worldwide. Despite its severity, the treatment methods for hepatocellular carcinoma are limited due to poor prognosis. This study identified the short hairpin RNA‐mediated silencing of myosin VI as a potential approach for the treatment of hepatocellular carcinoma. Firstly, the expression of myosin VI was analyzed in 57 hepatocellular carcinoma samples and 10 non‐neoplastic samples by immunohistochemistry. The results demonstrated that myosin VI expression was much stronger in hepatocellular carcinoma tissues than in adjacent normal tissues. Myosin VI short hairpin RNA was then transduced into HepG2 and SMMC‐7721 hepatocellular carcinoma cell lines, respectively, using a lentivirus delivery system. Knockdown of myosin VI led to a significant reduction in cell proliferation and colony‐forming capacity, as well as a blockade of cell cycle progression. Moreover, an obvious decrease in PRAS40 phosphorylation and a concomitant increase in p38 phosphorylation were observed in myosin VI knockdown cells, which suggest that myosin VI silencing inhibits hepatocellular carcinoma cell growth in vitro probably via inactivation of PRAS40 and activation of p38 mitogen‐activated protein kinase‐dependent signaling pathway. This study highlights the potential of myosin VI to be developed as a target for hepatocellular carcinoma therapy.

SummaryBackgroundThe relationship between helminthiases and allergy is a matter of considerable interest and research. In the tropics, house dust mite exposure, a known risk factor for asthma, is frequently concurrent with helminth infections. It remains to be defined whether infection with the common roundworm Ascaris or its bystander immunological effects influence the prevalence and pathogenesis of asthma independently of mite sensitization.ObjectiveTo investigate the relationship between the IgE responses to Ascaris and its purified allergens and the risk of asthma in a tropical country.MethodsA nested case–control study was performed in 356 subjects who reported current and past asthma symptoms (asthmatics) and 435 controls that had never experienced such symptoms. They were tested for serum levels of total IgE and specific IgE to Ascaris extract, Asc s 1 (ABA‐1), Asc l 3 (tropomyosin) and GST (glutathione transferase). In addition, specific IgE to Dermatophagoides pteronyssinus, Blomia tropicalis and their tropomyosins Der p 10 and Blo t 10 was measured. Sensitization was defined as a positive specific IgE result to any extract or recombinant allergen.ResultsSensitization to Ascaris and D. pteronyssinus was independently associated with asthma after adjustment for age, gender, socio‐economic stratum, city and other IgE levels (adjusted ORs: 2.17; 95% CI 1.37–3.42 and 2.46; 95% CI 1.54–3.92), respectively. There was also a significant association with sensitization to the highly allergenic and cross‐reactive tropomyosins Asc l 3, Blo t 10 and Der p10 (aORs: 1.76; 95% CI 1.21–2.57, 1.64; 95% CI 1.14–2.35 and 1.51; 95% CI 1.02–2.24), respectively.Conclusion and Clinical RelevanceIgE responses to Ascaris are associated with asthma symptoms in a population living in the tropics. Sensitization to the cross‐reactive Ascaris and mite tropomyosins partially underlies this finding. These results have potential relevance in asthma diagnosis and management.

ObjectiveTo investigate the oncologic and survival outcomes of primary transoral laser microsurgery in laryngeal cancer.DesignRetrospective analysis of a database of all patients undergoing primary transoral laser microsurgery with or without adjunctive therapy from June 2000 to October 2013. The median follow‐up time was 33 months.SettingA teaching hospital.ParticipantsTwo hundred and three patients underwent primary transoral laser microsurgery. Of these, 166 had glottic and 37 had supraglottic squamous cell carcinoma.Main outcome measuresOverall survival, disease‐specific survival, local control and rate of salvage laryngectomy.ResultsPrimary transoral laser microsurgery was performed exclusively in 149 (73%) patients, 16 (8%) had transoral laser microsurgery followed by postoperative (chemo)radiotherapy, 6 (3%) had transoral laser microsurgery with neck dissection, and 32 (16%) had transoral laser microsurgery in combination with neck dissection and postoperative (chemo)radiotherapy. In glottic cancer, the 5‐year local control was 86%, 86% and 76% in carcinoma in situ (Tis), early‐stage (T1, T2) and late‐stage (T3, T4) disease, respectively. The 5‐year disease‐specific survival was 93% in Tis, 96% in early‐stage and 65% at late‐stage disease. In supraglottic cancer, the 5‐year local control was 66% in early‐stage and 88% in late‐stage disease. The 5‐year disease‐specific survival was 80% and 75%, respectively. The rate of salvage laryngectomy was 9.9%.ConclusionIn carefully selected patients with laryngeal cancer, primary transoral laser microsurgery with or without adjunctive therapy can be organ preserving. It can provide a valid treatment option for patients.

SummaryBackgroundChronic hand eczema is a common dermatological disorder of multifactorial aetiology. It affects physical, material, social and psychological aspects of life, thereby impairing health‐related quality of life.ObjectivesThe aim of the present study was to assess quality of life, anxiety, depression and obsessive‐compulsive tendencies in patients with chronic hand eczema.Materials and methodsSeventy‐one patients with chronic hand eczema were included in the study. Quality of life was evaluated according to the Dermatology Life Quality Index (DLQI). Patients were also assessed for anxiety and depression with the Hospital Anxiety and Depression Scale (HADS), and for compulsive behaviour with the Leyton Trait Scale.ResultsThe DLQI score was 11.11 ± 1.81 in patients with chronic hand eczema. Scores on the Leyton Trait Scale were significantly higher than those of healthy controls (p < 0.027). As concerns the HADS‐Anxiety subscale, patients with hand dermatitis had statistically significantly higher scores than those of volunteers (p = 0.002). In contrast, no statistically significant difference was found between the two groups with regard to the HADS‐Depression subscale score and total HADS score.ConclusionHand eczema treatment should address the severity of skin lesions as well as the psychological impact of hand eczema.
