The role of constituency Offices in enhancing democracy and communication between members of parliament and their electorates: The case of Kabwata Constituency

This study sought to examine the role of Kabwata Constituency Office in enhancing democracy and communication between the Member of Parliament and the constituents in Kabwata, Lusaka. The constituency offices were established as part of the parliamentary reforms which the National Assembly embarked on with the re-introduction of Multi-party democracy in 1991. The offices aim at improving the constituent-Member relations and also to enhance the representative functions of Members of Parliament.The study was done using in depth interviews with two key stakeholders and a quantitative survey method of 100 constituents selected using clustered methodology. The results from the study revealed that majority of the people knew of the existence of the office. However, despite this only very few had visited the constituency office. The study further revealed that this could be attributed to the lack of adequate sensitisation programmes on the existence and purpose of the office. The study revealed that more still needs to be done if the offices are to fully serve their intended purpose. The study further revealed that there was need to engage the people so that they fully understand their role in the operations of the constituency office. Enhanced sensitisation campaigns therefore, need to be undertaken. This also calls for enough resources to be allocated to the constituency offices in order for them to be able to carry out sensitisation campaigns

The Human Side of Digital Technology: Supporting the Inclusion of Refugees in Higher Education Through Blockchain-backed EQPR

The spectrum of digital technologies that impact Higher Education (HE) is broad. This study explores the potential of Blockchain (BC) technology in the personalized learning path creation and data exchange in the learning processes. The flexibilization of education and digitizing student data through Blockchain may contribute to a more inclusive and sustainable HE system. According to the EU, the Blockchain supports sustainability in four main aspects: cybersecurity, accountability, transparency, and traceability. These aspects are also a driver of social impact and a higher capacity to include disadvantaged groups, such as refugees. Therefore, it is essential to start a debate between scholars and professionals about how the actors in the HE system engage in a collective meaning-making effort to sustain the adoption, diffusion, and use of BC for HE. The paper focuses on the experience of CIMEA DiploMe and EQPR for the recognition of refugees' qualifications. Through a collective consensus-making and awareness-raising effort, the blockchain-backed EQPR could be perceived as a critical tool to foster inclusion within the HEIs and enhance their social outreach

Alpha decay rate enhancement in metals: An unlikely scenario

It has been recently suggested that one might drastically shorten the alpha lifetime of nuclear waste products, if these are embedded in metals at low temperatures. Using quantum mechanical tunneling arguments, we show that such an effect is likely to be very small, if present at all.Comment: RevTeX4. 5 pages, 1 figure. Accepted by Nucl. Phys.

Low-Energy Nuclear Astrophysics - the Fascinating Region of A=7

We discuss results and future plans for low-energy reactions that play an important role in current nuclear astrophysics research and that happen to concentrate around the region of A=7. The 7Be(p,gamma)8B and the 3He(4He,gamma)7Be reactions are crucial for understanding the solar-neutrino oscillations phenomenon and the latter one plays a central role in the issue of cosmic 7Li abundance and Big-Bang Nucleosynthesis. We also present results regarding the host dependence of the half life of the electron-capture 7Be radio-nuclide.Comment: 8 pages, 6 figures. Proceedings of the Erice School on Nuclear Physics, 2006.

On the absence of appreciable half-life changes in alpha emitters cooled in metals to 1 Kelvin and below

The recent suggestion that dramatic changes may occur in the lifetime of alpha and beta decay when the activity, in a pure metal host, is cooled to a few Kelvin, is examined in the light of published low temperature nuclear orientation (LTNO) experiments, with emphasis here on alpha decay. In LTNO observations are made of the anisotropy of radioactive emissions with respect to an axis of orientation. Correction of data for decay of metallic samples held at temperatures at and below 1 Kelvin for periods of days and longer has been a routine element of LTNO experiments for many years. No evidence for any change of half life on cooling, with an upper level of less than 1%, has been found, in striking contrast to the predicted changes, for alpha decay, of several orders of magnitude. The proposal that such dramatic changes might alleviate problems of disposal of long-lived radioactive waste is shown to be unrealistic.Comment: 27 pages, 12 figures, accepted for publication in Nucl.Phys.A. Revised version, including quantitative analysis of the sensitivity of nuclear orientation experiments, discussed in this work, to changes of alpha-decay lifetimes in metals at low temperatures. Conclusions remain unchange

Comparison of the LUNA 3He(alpha,gamma)7Be activation results with earlier measurements and model calculations

Recently, the LUNA collaboration has carried out a high precision measurement on the 3He(alpha,gamma)7Be reaction cross section with both activation and on-line gamma-detection methods at unprecedented low energies. In this paper the results obtained with the activation method are summarized. The results are compared with previous activation experiments and the zero energy extrapolated astrophysical S factor is determined using different theoretical models.Comment: Accepted for publication in Journal of Physics

Impact of a revised 25^{25}Mg(p,γ\gamma)26^{26}Al reaction rate on the operation of the Mg-Al cycle

Proton captures on Mg isotopes play an important role in the Mg-Al cycle active in stellar H-burning regions. In particular, low-energy nuclear resonances in the $^{25}$Mg(p,$\gamma$)$^{26}$Al reaction affect the production of radioactive $^{26}$Al$^{gs}$ as well as the resulting Mg/Al abundance ratio. Reliable estimations of these quantities require precise measurements of the strengths of low-energy resonances. Based on a new experimental study performed at LUNA, we provide revised rates of the $^{25}$Mg(p,$\gamma$)$^{26}$Al$^{gs}$ and the $^{25}$Mg(p,$\gamma$)$^{26}$Al$^{m}$ reactions with corresponding uncertainties. In the temperature range 50 to 150 MK, the new recommended rate of the $^{26}$Al$^{m}$ production is up to 5 times higher than previously assumed. In addition, at T$=100$ MK, the revised total reaction rate is a factor of 2 higher. Note that this is the range of temperature at which the Mg-Al cycle operates in an H-burning zone. The effects of this revision are discussed. Due to the significantly larger $^{25}$Mg(p,$\gamma$)$^{26}$Al$^{m}$ rate, the estimated production of $^{26}$Al$^{gs}$ in H-burning regions is less efficient than previously obtained. As a result, the new rates should imply a smaller contribution from Wolf-Rayet stars to the galactic $^{26}$Al budget. Similarly, we show that the AGB extra-mixing scenario does not appear able to explain the most extreme values of $^{26}$Al/$^{27}$Al, i.e. $>10^{-2}$, found in some O-rich presolar grains. Finally, the substantial increase of the total reaction rate makes the hypothesis of a self-pollution by massive AGBs a more robust explanation for the Mg-Al anticorrelation observed in Globular-Cluster stars
