- Description: Post-apartheid education policy in South Africa mandates that universities should become more responsive to the socio-economic development of the country, positioning community engagement as a core function of higher education. Community engagement in all its forms, and particularly in the form of community-based research, should develop the social responsibility of both students and the institution by providing opportunities for partnering in community-based projects to promote the social good, thus narrowing the gap between universities and communities. The Community Engagement Division at Rhodes University in the Eastern Cape province of South Africa, supported by the highest level of management of the institution, was fully aware that removal of the ‘ivory tower’ image was a herculean task. Thus, they developed a set of values and principles to guide the establishment of community partnerships with the community the university serves. This chapter explains these values and principles, using the Reviving Schools community engagement initiative as an example. It discusses some of the challenges experienced and how they were overcome to build research relationships and a sense of ‘community’ between Rhodes University and its external partners in Makhanda.

- Description: Information Communication Technology is recognised worldwide for its contribution towardsSMTEs development and the economy. However, the level of ICT implementation as a management tool, its contribution and the extent of benefits on SMTEs is a debateable phenomenon. The purpose of this study was to investigate the barriers to the implementation of ICT within the context of small and medium tourism enterprises in Hogsback. Both quantitative and qualitative research methods were applied in this study. Questionnaire interviews were conducted with owner/managers in Hogsback. The stratified sampling methodwas utilised to collect data. The study indicates that (46.2%) of the business respondents wereoperating the accommodation establishments. The findings of the study underscores that (25.6%) of the business owners identified the barriers of ICT appears to be high costs. Further(23.1%) stated that accessing technology was also an impediment. Moreover, the study elucidates that (94.9%) of the SMTE concur that implementation ICT as a management tool helps to meet objectives of the business for the daily operations of the business. It is therefore recommended that ICT be implemented as a management tool for small and medium tourism enterprises. Furthermore, the study recommends that the managers/owners should invest in technology to ensure the success of the SMTEs in all aspects. Furthermore, the study serves asthe basis for future studies in the area of ICT within the SMTE sector

- Description: In 1992, the international Convention on Biological Diversity (CBD) emphasised biodiversity as a measure for sustainabil-ity and recognised communication, education and public awareness as important for the successful implementation of the Convention’s aims (CBD 1992). In 2002, the United Na-tions Decade of Education for Sustainable Development (2005–2014) included biodiversity as one of its key priorities (Unesco 2005). Later, Unesco’s (2014) Global Action Plan on Education for Sustainable Development highlighted biodiver-sity as ‘critical content’, to be included in national curricula for holistic and transformational education. In 2015, the United Nations included a concern for biodiversity in the Sustainable Development Goals, making a commitment that: We recog-nise that social and economic development depends on the sustainable management of our planet’s natural resources. We are therefore determined to conserve and sustainably use oceans and seas, freshwater resources, as well as for-ests, mountains and dry lands and to protect biodiversity, ecosystems and wildlife. (United Nations 2015: 13).

- Description: The study was informed by an expansion of the ‘design research’ reported by McKenny and Reeves (2012) and it developed as a collaborative design process similar to that described by Voogt, Laferriere, Breuleux, Itow, Hickey and McKenny (2015). Voogt et al. approached design research as a successive and developing process of formative work by participants working together to design and assess a learning programme. In our case the design work was undertaken within a course-supported process of ESD design innovation among participating teachers and subject advisors.

- Description: No education policy, no matter how well designed, can succeed without a teacher (Sanyal 2013). Additionally, a change in policy alone is not sufficient to improve an education system (Livingstone 2012), no matter how well meaning. The quality of teachers’ professional practices determines to some extent the quality of teaching and learning in the schooling sector. Teacher quality, and not only teacher supply, is important for learning; hence, teacher professional development should be a priority in all education and development strategies (Unesco 2015a).

- Description: More than three decades of research have failed to achieve convergence on a method for the measurement of non-profit financial condition, with the literature reporting a bewildering array of financial dimensions, and more than 100 ratios and indicators. This article offers a contribution to a broader discourse in non-profit financial analysis by recognising, and taking action in response to, the potential threat to research validity arising from the generally unchallenged presumption that accounting numbers provide a complete, unbiased and error-free representation of an entity’s underlying economic reality.

- Description: Using the Bondi-Sachs formalism, the problem of a gravitational wave source surrounded by a spherical dust shell is considered. Using linearized perturbation theory, the geometry is found in the regions: in the shell, exterior to the shell, and interior to the shell. It is found that the dust shell causes the gravitational wave to be modified both in magnitude and phase, but without any energy being transferred to or from the dust.

- Description: The Convention on Biological Diversity and the Nagoya Protocol establish that genetic resources shall be accessed only upon the existence of prior informed consent of the country that provides those resources and that benefits arising from their utilization shall be shared. Pursuant to both agreements several countries have adopted regulations on access and benefit-sharing. These regulations have created a challenging obstacle to classical biological control of weeds. This paper reviews the experiences of Argentina, Brazil, South Africa, the USA, Canada and CABI in implementing access and benefit-sharing regulations and the implications these measures have on the effective and efficient access, exchange and utilization of biological control agents.

- Description: Predation is a pervasive force that structures food webs and directly influences ecosystem functioning. The relative body sizes of predators and prey may be an important determinant of interaction strengths. However, studies quantifying the combined influence of intra‐ and interspecific variation in predator–prey body size ratios are lacking. We use a comparative functional response approach to examine interaction strengths between three size classes of invasive bluegill and largemouth bass toward three scaled size classes of their tilapia prey. We then quantify the influence of intra‐ and interspecific predator–prey body mass ratios on the scaling of attack rates and handling times.

- Description: South Africa has potential to export honey products through promoting beekeeping as an income generating opportunity amongst rural communities. Formalised beekeeping may also reduce wild fires initiated by hunters of wild bee hives. This study examined the contribution of the African Honey Bee (AHB) initiative to rural livelihoods and the incidence of forest fires using a mixed methods approach. The initiative increased incomes of newly trained and active beekeepers, although success rates and honey yields were variable. Core challenges included not catching bees, theft and vandalism of hives, insufficient bee forage, drought and pests. Most respondents also perceived an increase in crop size since AHB began, although few attributed this to pollination from the bees. The number of wild fires attributed to honey hunters more than halved after AHB began. Future steps need to reduce the challenges and integrate beekeeping into broader agriculture and forest conservation programmes.

- Description: Mitochondrial DNA (mtDNA) has long been used to date historical demographic events. The idea that it is useful for molecular dating rests on the premise that its evolution is neutral. Even though this idea has long been challenged, the evidence against clock-like evolution of mtDNA is often ignored. Here, we present a particularly clear and simple example to illustrate the implications of violations of the assumption of selective neutrality.

This paper presents the most sensitive and highest resolution images of NGC 6251 at these frequencies to date, revealing for the first time a low-surface-brightness extension to the northern lobe, and a possible backflow associated with the southern lobe. The integrated spectra of components of NGC 6251 are consistent with previous measurements at higher frequencies, similar to results from other LOFAR studies of nearby radio galaxies.

- Description: Many university writing and student academic development centres serve both under-and postgraduate student-writers. However, it is not always clear that the training and development of those who work with writers accounts fully for the affective dimensions of postgraduate writing, specifically. Especially at the doctoral level, where an original contribution to knowledge is required, writers need to take on a confident authorial voice in their work, both written and in conversation with others. Research, however, shows that many doctoral students struggle with this. This paper argues that, to be truly successful and fit for purpose, peer writing development work needs to understand the nature of postgraduate learning and writing from more than just the technical perspective of writing a successful thesis. Writer-focused work at this level needs to account for the affective dimensions of writing and research as well, to engage students in more holistic, critical, and forward-looking conversations about their writing, and their own developing scholarly identity. The paper offers insights into the different affective dimensions of postgraduate writing, especially those under-considered in much practical work with postgraduate writers, and offers suggestions for a whole-student tutoring approach at this level.

Adapted from the diary methods of psychology and media studies audience research, it is designed to foreground tacit and mundane data about everyday mobile phone practices. The diary interview reconstructs details of the social practices of everyday life that make up each participant’s “yesterday” and situates mobile practices within this account. To illustrate the method, we provide examples from our study, Izolo, that spanned three distinct South African neighbourhoods in different parts of the country and focused on less-connected people.

- Description: Compounds incorporating ferrocene in a aminocresol scaffold showed antiplasmodial and anticancer activity. SAR studies revealed that an OH group and rotatable C–NH bond are vital for biological activity, with spectrophotometric techniques and docking simulations suggesting a dual mode of action involving hemozoin inhibition and DNA interaction. Targeting multiple pathways could delay the development of clinical resistance.

This phenomenon has been investigated in a number of domains and we extend the body of research with an investigation in the IoT domain. We presented participants with evidence of a specific IoT device’s (smart plug) privacy violations and then measured changes in privacy concerns and trust, as well as uptake of a range of behavioural responses. Our Saudi Arabian participants, despite expressing high levels of privacy concerns, generally chose not to respond to this evidence with preventative action.

- Description: Asymmetric mono-carboxy-porphyrins, (5-(4-carboxyphenyl)−10,15,20-tris(pentafluorophenyl)porphyrinato zinc(II) (1), 5-(4-carboxyphenyl)−10,15,20-triphenylporphyrinato zinc(II) (2) and 5-(4-carboxyphenyl)−10,15,20-tris(2-thienyl)porphyrinato zinc(II) (3), were linked to Ag nanoparticles (AgNPs) through amide bonds and self-assembly (the latter only for 3). The porphyrins and conjugates were used for photodynamic antimicrobial chemotherapy (PACT) against Staphylococcus aureus. PACT uses singlet oxygen for antimicrobial activity. Complex 3 and its conjugates had higher singlet oxygen quantum yields and higher log reduction when compared with the rest of the porphyrins and corresponding conjugates. These high log reductions for 3 and its conjugate were attributed to the presence of sulfur groups whereby there was more interaction with the bacterial membrane.
