Subject |
The social and environmental implications of Africa's rising energy demand. |
Significance |
Africa’s energy development poses fundamental social and environmental challenges. Rapid population growth combined with industrialisation and urbanisation imply large increases in energy demand, much of which is expected to be met by fossil fuels, undermining sustainability goals. Yet increased energy use is critical... |
Impacts |
The poor state of electricity infrastructure will retard large-scale electrification, encouraging recourse to off-grid renewables. |
Weak infrastructure will also increase the degree to which future energy demand is met by fossil fuels. |
Distributed solar and micro-solar use will expand most rapidly where mobile banking has already penetrated. |

This paper explores multiple published articles regarding the societal assumption that women’s sports are less competitive and less engaging than men’s sports. Some articles, such as Women’s Sports Foundation (2010) and Carpenter & Acosta (2005),cite lack of funds and media visibility as to why women’s sports are not a... |
The huge collections of news content which have become available through digital technologies both enable and warrant scientific inquiry, challenging journalism scholars to analyse unprecedented amounts of texts. We propose Latent Dirichlet Allocation (LDA) topic modelling as a tool to face this challenge. LDA is a cut... |
Various bodies participated in offering public services besides the Palestinian National Authority government, such as the UNRWA agency, the NGOs which have a significant role in offering social, health and educational free or subsidized services, and finally, international aids and UN firms render funds for the purpos... |
This paper considers whether it is possible to classify physician assisted suicide (PAS) as a ‘service’ for the purposes of Article 49 of the European Community Treaty. It suggests that if PAS were to be formally recognised as a ‘service’ for the purposes of European Community (EC) Law, it is unlikely that the UK Gover... |
We consider smooth area-preserving flows (also known as locally Hamiltonian flows) on surfaces of genus $g\geq 1$ and study ergodic integrals of smooth observables along the flow trajectories. We show that these integrals display a \emph{power deviation spectrum} and describe the cocycles that lead the pure power behav... |
Cloud computing is an emerging technology that is still uncertain to many security problems. Ensuring the security of stored data in cloud servers is one of the most challenging issues in such environments. RSA provide secure transmission over transmission channel. Main advantage of RSA is prime factorization. With the... |

Four horses with a history of chronic diarrhoea and weight loss were studied. Three of them revealed malabsorption, as indicated by decreased absorption of D(+)-xylose. Three patients had distinct hypoalbuminaemia, and 131I-albumin turnover rates of these three horses were increased, compared to two normal control hors... |
STS scholars frequently have shown how science and sociopolitical arrangements are ‘co-produced’, typically tracing how scientific actors themselves keep ‘science’ and ‘politics’ far apart. Revealing co-production is therefore deemed the work of the STS analyst, who unearths linkages that the actors might be unaware of... |
The problem of the interference of celiac disease (CD) with the male reproductive system is made evident both by the recognized adverse effects on female reproduction and by the multifactorial nature of the disease. It is important to consider CD as a multifactorial condition since its diverse effects can be modulated,... |

Immunoglobulin-(Ig-) and T-cell-receptor-(TcR-)gene rearrangements were investigated in peripheral blood lymphocytes (PBL) of patients with various autoimmune disorders. In patients with SLE there was no predominant Ig- or TcR-gene rearrangement. This was also true in patients with a long disease duration and with exce... |
Aggressive instruction scheduling leaves behind many renaming copy instructions that cannot be coalesced due to interferences. These copies take resources, and more seriously, they may cause a stall if they are generated for renaming of multi-latency instructions. This paper proposes a code transformation technique bas... |
Our empirical study performed on a 16-ALU VLIW testbed with a two-cycle load latency shows that 86% of the otherwise uncoalescible copies in innermost loops become coalescible when unrolled 2.2 times on average. In addition, it is demonstrated that the unroll amount obtained is precise and the most efficient. The unrol... |

CONTEXT |
Although the nation's local health departments (LHDs) share a common mission, variability in administrative structures is a barrier to identifying common, optimal management strategies. There is a gap in understanding what unifying features LHDs share as organizations that could be leveraged systematically for achievin... |
OBJECTIVE |
To explore sources of commonality and variability in a range of LHDs by comparing intraorganizational networks. |
INTERVENTION |
We used organizational network analysis to document relationships between employees, tasks, knowledge, and resources within LHDs, which may exist regardless of formal administrative structure. |
SETTING |
A national sample of 11 LHDs from seven states that differed in size, geographic location, and governance. |
PARTICIPANTS |
Relational network data were collected via an on-line survey of all employees in 11 LHDs. A total of 1062 out of 1239 employees responded (84% response rate). |
