Realising political equality: the European Court of Human Rights and positive obligations in a democracy'

The European Convention on Human Rights (ECHR) speaks of the importance of an “effective political democracy” in its Preamble, though it is only in Article 3 of Protocol 1 (P1-3) that we find a right to free elections. This paper discusses the role of “positive obligations” under P1-3. This paper outlines the positive obligations in P1-3 focusing on obligations where the state is required to do more than just change the law. This may mean providing resources or facilities, adopting regulatory frameworks or creating new institutions. The paper highlights specific positive obligations that need to be further developed in the jurisprudence of the European Court of Human Rights (ECtHR). Sometimes these can be developed by analogy with positive obligations recognised in other areas of ECtHR jurisprudence. However, beyond these cases, states should ensure that members of vulnerable and disadvantaged minorities are able to participate in the electoral process and should ensure that dominant political groups cannot abuse their political power to exclude other parties unfairly. This is necessary to realise equal political rights. The second section of this paper sketches some preliminary points about the Strasbourg institutions’ approach to P1-3. After that, the third section identifies circumstances where the ECtHR should apply a more intense scrutiny in P1-3 cases. The fourth, fifth and sixth sections look at positive obligations relating to the right to vote, the right to run for election and the regulation of political parties.

The effect of animals on human health and well-being

Substantial sums of money are invested annually in preventative medicine and therapeutic treatment for people with a wide range of physical and psychological health problems, sometimes to no avail. There is now mounting evidence to suggest that companion animals, such as dogs and cats, can enhance the health of their human owners and may thus contribute significantly to the health expenditure of our country. This paper explores the evidence that pets can contribute to human health and well-being. The article initially concentrates on the value of animals for short- and long-term physical health, before exploring the relationship between animals and psychological health, focusing on the ability of dogs, cats, and other species to aid the disabled and serve as a "therapist" to those in institutional settings. The paper also discusses the evidence for the ability of dogs to facilitate the diagnosis and treatment of specific chronic diseases, notably cancer, epilepsy, and diabetes. Mechanisms underlying the ability of animals to promote human health are discussed within a theoretical framework. Whereas the evidence for a direct causal association between human well-being and companion animals is not conclusive, the literature reviewed is largely supportive of the widely held, and long-standing, belief that "pets are good for us." © 2009 The Society for the Psychological Study of Social Issues.

Exchange protein directly activated by cAMP 1 (Epac1) is expressed in human neutrophils and mediates cAMP-dependent activation of the monomeric GTPase Rap1

Epac1 and Epac2 bind cAMP and mediate cAMP-dependent activation of Rap1. cAMP is produced in neutrophils in response to many chemoattractants. This second messenger plays a key role in the regulation of the functions of neutrophils. However, it is still not known whether Epacs are expressed in human neutrophils. We found that stimulation of PLB-985 cells differentiated into neutrophil-like cells, human neutrophils with 8CPT-2Me-cAMP (a selective activator of Epacs), or FK (a diterpene that augments the intracellular level of cAMP) led to GTP-loading of Rap1. Epac1 mRNA was expressed in UND and DF PLB-985 cells, but Epac1 protein was only detected in DF PLB-985 cells. In human neutrophils, the Epac1 transcript was present, and Epac1 protein could be detected by Western blot analysis if the cells had been treated with the serine protease inhibitor PMSF. FK induced adhesion of PLB-985 cells and human neutrophils on fibrinogen, a ligand for beta 2 integrins. Interestingly, in DF PLB-985 cells, but not in human neutrophils, 8CPT-2Me-cAMP induced beta 2 integrin-dependent adhesion. The failure of 8CPT-2Me-cAMP to induce beta 2 integrin-dependent human neutrophil adhesion could be explained by the fact that this compound did not induce a switch of the beta 2 integrins from a low-affinity to a high-affinity ligand-binding conformation. We concluded that Epac1 is expressed in human neutrophils and is involved in cAMP-dependent regulation of Rap1. However, the loading of GTP on Rap1 per se is not sufficient to promote activation of beta 2 integrins. J. Leukoc. Biol. 90: 741-749; 2011.

The Development of Entrepreneurial Leadership: The Role of Human, Social and Institutional Capital

This paper contributes to the literature on entrepreneurial leadership development. Leadership studies are characterized by an increasing emphasis given to an individual leader's social and organizational domain. Within the context of human capital and social capital theory, the paper reflects on the emergence of a social capital theory of leadership development. Using a retrospective, interpretivist research method, the authors present the experience of a cohort of business leaders on an executive development programme to uncover the everydayness of leadership development in practice. Specifically, they explore how entrepreneurial leadership develops as a social process and what the role of social capital is in this. The findings suggest that the enhancement of leaders’ human capital only occurred through their development of social capital. There is not, as extant literature suggests, a clear separation between leader development and leadership development. Further, the analysis implies that the social capital theory of leadership is limited in the context of the entrepreneurial small firm, and the authors propose that it should be expanded to incorporate institutional capital, that is, the formal structures and organizations which enhance the role of social capital and go beyond enriching the human capital stock of individual leaders

AM1- receptor dependent protection by intermedin of human vascular and cardiac non-vascular cells from ischaemia-reperfusion injury

Intermedin (IMD) protects rodent heart and vasculature from oxidative stress and ischaemia. Less is known about distribution of IMD and its receptors and the potential for similar protection in man. Expression of IMD and receptor components were studied in human aortic endothelium cells (HAECs), smooth muscle cells (HASMCs), cardiac microvascular endothelium cells (HMVECs) and fibroblasts (v-HCFs). Receptor subtype involvement in protection by IMD against injury by hydrogen peroxide (H2O2, 1 mmol l?¹) and simulated ischaemia and reperfusion were investigated using receptor component-specific siRNAs. IMD and CRLR, RAMP1, RAMP2 and RAMP3 were expressed in all cell types.When cells were treated with 1 nmol l?¹ IMD during exposure to 1 mmol l?¹ H2O2 for 4 h, viability was greater vs. H2O2 alone (P<0.05 for all cell types). Viabilities under 6 h simulated ischaemia differed (P<0.05) in the absence and presence of 1 nmol l?¹ IMD: HAECs 63% and 85%; HMVECs 51% and 68%; v-HCFs 42% and 96%. IMD 1 nmol l?¹ present throughout ischaemia (3 h) and reperfusion (1 h) attenuated injury (P<0.05): viabilities were 95%, 74% and 82% for HAECs, HMVECs and v-HCFs, respectively, relative to those in the absence of IMD (62%, 35%, 32%, respectively). When IMD 1 nmol l?¹ was present during reperfusion only, protection was still evident (P<0.05, 79%, 55%, 48%, respectively). Cytoskeletal disruption and protein carbonyl formation followed similar patterns. Pre-treatment (4 days) of HAECs with CRLR or RAMP2, but not RAMP1 or RAMP3, siRNAs abolished protection by IMD (1 nmol l?¹) against ischaemia-reperfusion injury. IMD protects human vascular and cardiac non-vascular cells from oxidative stress and ischaemia-reperfusion,predominantly via AM1 receptors.

Early Holocene vegetation, human activity and climate from Sarawak, Malaysian Borneo

A 40mcore from Loagan Bunut,Malaysian Borneo, yielded a high-resolution early Holocene (11.3e6.75 ka) sequence of marginal-marine deposits. Palynological analysis showed relatively stable fire-regulated lowland forest through this time, with the local development and regression of mangrove vegetation. A general trend of rising rainfall and thus strengthening North East monsoonal circulation linked to the migration of the mean position of the ICTZ was interrupted by what may be episodes of drier climate and weakening monsoonal activity at 9250-8890, 7900 and 7600-7545 cal. BP. Magnetic susceptibility peaks suggestmarked short-term ENSO-style activity superimposed upon this record. Repeated markers for openand disturbed habitats, plus occasional imported and probably-cultivated taxa, point towards human impact from the earliest Holocene on the wet tropical forest at Loagan Bunut.
