BackgroundMalnutrition is common after stroke. Stroke patients often have a suboptimal energy intake, body weight and inadequate blood nutrient levels. Nutrient insufficiencies may not be detected, but their recognition is essential to provide adequate nutritional support after a stroke. This comprehensive summary of the literature is a collection of data on blood levels of a broad selection of nutrients involved in restoring cerebral blood flow and functional brain connectivity in stroke patients compared to controls.MethodsEmbase and MEDLINE were searched for studies published in English in the period 1980–2022. Studies including adult stroke subjects and controls whose blood samples were analyzed for docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), uridine, choline, folate, vitamin B6, vitamin B12, vitamin C, vitamin E, selenium, coenzyme Q10 (CoQ10), carnitine, arginine, or taurine were selected. If there were &gt;3 reports (k) per nutrient, results were generated with an unadjusted and age-adjusted random-effects meta-analysis model. Risk of bias was evaluated for relevant domains from the ROBINS-I tool and with Egger's test.ResultsOne hundred five reports on blood nutrient levels were extracted from 56 eligible studies. Overall, meta-analyses showed lower blood levels of most nutrients in stroke patients compared to controls. The number of reports and the statistical significance for the unadjusted data were: folate (k = 27; p = 0.005), vitamin B12 (k = 23; p = 0.002), vitamin E (k = 11; p = 0.013), DHA (k = 7, p = 0.015), EPA (k = 7; p = 0.004), vitamin C (k = 6; p = 0.020), and selenium (k = 6; p = 0.018). No significant decreases were observed for vitamin B6 (k = 6; p = 0.52) and arginine (k = 4; p = 0.93). For other selected nutrients, there were insufficient reports to perform a meta-analysis. Available reports pointed toward lower (CoQ10, choline; k = 2), higher (taurine; k = 2), or unchanged (carnitine, uridine; k = 1) blood levels after stroke. In general, risk of bias was low.ConclusionOur findings indicate that nutrient insufficiencies occur for many nutrients that are involved in repair processes after stroke. The low blood levels of folate, vitamin B12, EPA, DHA, vitamin C, vitamin E, selenium, and possibly CoQ10 and choline, highlight the presence of a suboptimal nutritional status after stroke. The inclusion of targeted nutritional interventions to further support recovery should receive consideration in the multidisciplinary context of stroke rehabilitation.

Published: December 2023

IntroductionThe evaluation on the trade-off/synergy relationship of urban cultivated land-use function conflicts (CLUFCs) for improving the sustainability of cultivated land ecosystem is one of the solutions to coordinate the contradiction between land health and economic development and alleviate food crises, and achieve “zero hunger” in the United Nations Sustainable Development Goals (SDGs).MethodsIn this study, Yancheng City was taken as the research object, and the cultivated land ecological function (CLEF) was evaluated by the morphological spatial pattern analysis-minimum cumulative resistance (MSPA-MCR) model from the perspective of multi-objective coordinated development of cultivated land, and cultivated land productive function (CLPF) was evaluated by net primary productivity (NPP). In addition, combined with local indications of spatial association (LISA) analysis, the spatial trade-off/synergy relationship between CLPF and CLEF was quantified and analyzed. The spatial principal co-coordinates-redundancy analysis (SPCoA-RDA) was used to explore the influencing factors and mechanisms of CLUFCs.ResultsThe results show that there are obvious spatial heterogeneity and aggregation distribution characteristics of CLUFCs in Yancheng City. Through SPCoA-RDA, it is found that the spatial differentiation of CLUFCs is the result of the combination of internal (population density, road network, and water network) and external (spatial spillover effect) driving factors.DiscussionBased on these results, the study area was divided into eight types of cultivated land suitability zones under four aggregation relationships of CLUFCs. Comprehensively considering production, CLUFCs were evaluated by socio-economic and geo-spatial statistical dates, and strategies for guiding the coordinated development and sustainable management of urban cultivated land had been put forward. This study can provide a theoretical framework and certain feasible suggestions for the sustainable development and the transformation of cultivated land system in agriculture cities.

Authors: Zulu Simangaliso Bayabonga , Phiri Maxwell 
Published: December 2023

Local governments provide a range of local services, preserve the life and liberty of residents, creating space for democratic participation and civic dialogue, supporting market-led and environmentally sustainable development. City branding supplies the principles for the city developing policy to sustain the local development. In other words, city branding means being powerful to face the increasing wild competition for resources, investment, and tourism facilities, both for addressing crucial social issues and cultural variation. The purpose of this study is (i) to investigate the role of local governments in city branding, (ii) to determine city branding contribution to local economic development (LED). Although there are plenty place branding techniques in the world, the success of the city branding strategy cannot be performed without the participation of a local government.
In addition, the current study selects the city of Durban in the Province of KwaZulu-Natal, South Africa as the context of the study and a local government to focus on. The problem is that the city of Durban has not been successful at making the city competitive enough to attract the needed investments. The city officials have also not been effectively marketing the city to the world to make known of its inherent potentials. This study seeks to overcome this issue by developing city branding strategies. The city management need to take proactive action in implementing them to effectively market the city to the world.
To achieve objectives, the study adopts the form of a mixed-methods approach, using quantitative (survey questionnaire) and qualitative (in-depth interview) as methods and instruments for data collection. The study follows a sequential design starting with quantitative and followed by qualitative data collection. Since the study employs both quantitative and qualitative methods, both purposive sampling (for qualitative phase) and simple random sampling (for quantitative phase) techniques will be selected. The researcher selected participants from Durban municipality. The study’s sample size constitutes 350 participants (N=320 was surveyed) and (30 were interviewed). The researcher analysed the data collected with questionnaires through descriptive and inferential statistics and data collected using in-depth interviews through content analysis.
Collecting data online from young students during a pandemic. Reflections.
Authors: Mangion Margaret 
Published: December 2023

As researchers we need to be able to reflect deeply to constantly improve the research processes. Reflection can help researchers to engage critically and objectively with the worldview while acknowledging what works and what doesn’t. This paper focuses on reflections emerging from online data collection during a pandemic.
This paper presents what was learned from conducting online research by collecting data through an online survey administered to school children during the Covid-19 pandemic. Following a brief review of relevant literature, the research process employed is outlined. This includes the sample, measures used and ethics clearance. Secondly, we explore the advantages and limitations of conducting online research. In particular we explore the issues that were encountered and how online research made data collection from a school possible during a pandemic. The main stumbling blocks were related to: (a) parental engagement and the subsequent collection of consent forms; (b) issues that emerged during the actual data collection. These issues and others are explored through a reflection process using cycle outlined by Gibbs (1988).
The aim of the study was to explore how students aged between 9 – 11 years perceived their own creative self-concept and their wellbeing at school. In this quantitative study, 530 students coming from different schools were surveyed using an online platform. Participants were recruited through their respective schools following the dissemination of information letters and consent forms. While various advantages emerged from conducting online research, a number of challenges were encountered throughout the process. This data collection exercise presented an opportunity for learning and growth through a process of reflection and evaluation.
Methodological procedure for the development of a qualitative and quantitative evaluation concept for project benefit assessment
Authors: Hizal Gamze Gül 
Published: December 2023

The fourth industrial revolution not only brings great opportunities for the economy, but also poses major challenges for all stakeholders. Manufacturing companies in particular are affected by challenges such as a lack of innovative strength or the risk of being overtaken by innovative start-ups. However, the dynamic environment and the resulting complexity require faster and better decisions to remain competitive in the long term. Current business practices of established companies do not meet this challenge and risk losing control of their core business. Taking a purely technological approach to this subject harbors costly risks. Only the integration of the various individual technologies into a holistic digital strategy creates efficiency and new growth areas. To exploit the full potential of Industry 4.0 (I4.0) in the manufacturing industry, companies must therefore take a strategic view of the technological options and adapt their organizational structure and culture.
The main objective of this paper is therefore to describe the procedure for developing a suitable evaluation concept for assessing the economic benefits of digitization projects. The evaluation concept to be developed is designed to be able to perform a multidimensional examination and evaluation of digitization projects in order to enable a quick and well-founded decision on the implementation as well as the prioritization of a specific project or several projects from a qualitative and quantitative point of view. The paper therefore describes a seven-step approach to developing a multidimensional matrix diagram that serves as the basic structure for such an evaluation concept.
To develop a suitable evaluation concept, the research focus will be carefully examined and in-depth research on two overarching themes will be conducted, resulting in the definition of appropriate evaluation criteria: From a methodological point of view, existing assessment models are considered in general and the strengths and weaknesses of these models are discussed. From a practical perspective, the special requirements of digitization and Industry 4.0 will be addressed. To this end, expert interviews will be conducted and a total of 100 practical examples will be selected from an extensive database and analyzed in a criteria-oriented manner in order to derive assessment dimensions and assessment criteria from both a quantitative and qualitative perspective.
Navigating the Intersection of Innovation and Cybersecurity: A Framework
Authors: Botha-Badenhorst Danielle 
Published: December 2023

Reliance on digital technologies for innovation management is unavoidable in current contexts. While digital processes and business models have been prioritised as key factors to drive innovation and value creation within firms, cybersecurity concerns are still rife. Increased levels and severity of cybersecurity breaches (CSBs) have had adverse effects on trust, caused significant revenue losses, and inflicted reputational damage on many firms. Further exacerbating these concerns is an observation made in the Global Risks Report of 2022, the World Economic Forum: cybersecurity measures taken by businesses are becoming increasingly obsolete. Many firms face severe consequences without implementing strategic objectives to limit the threats posed by CSBs. Cybersecurity breaches (CSBs) have a significant long-term impact on firm-level innovation and investment decisions. However, many firms are reluctant to examine or enhance their existing cybersecurity practices because of concerns that they may limit their innovation ability. Determining a method to limit CSBs and retain capabilities to perform necessary innovative processes is a delicate balance, with trade-offs to be considered within each process.
This paper aims to address the delicate balance between limiting CSBs and preserving the ability to undertake necessary innovative processes. Building upon the Cyber Security Maturity and Innovation matrix introduced by Nelson and Madnick (2017), this paper expands the framework by providing specific suggestions for each quadrant. The matrix classifies firms into different quadrants based on their reliance on innovation and their assessment of cyber risk. We then detail measures to improve cybersecurity maturity for firms in each quadrant, incorporating the National Institute of Standards and Technology (NIST) Cybersecurity Framework Version 1.1 (CSF) as a reference. By making well-informed decisions and implementing appropriate measures, firms can effectively mitigate CSB risks while continuing to drive innovation and create value. This expanded framework serves as a valuable tool for firms seeking to align their cybersecurity practices with their innovation objectives, in accordance with the NIST CSF.
Autoethnography as a research method in happiness studies
Authors: Casau Ana Margarida , Ferreira Dias Marta , Leite Mota Gabriel , Au-Yong-Oliveira Manuel 
Published: December 2023

The pursuit of happiness is a fundamental human goal that has been studied by philosophers, theologians, and scientists for centuries. Despite its universal importance, the definition and means of achieving happiness vary greatly across cultures and individual experiences (Uchida, Norasakkunkit and Kitayama, 2004). Cultures have different beliefs, values, and customs that shape their understanding of happiness. For example, some cultures may place a higher value on material wealth and success, while others may prioritize spiritual fulfilment or strong relationships (Joshanloo and Weijers, 2014). In this autoethnographic paper, I reflect on my own personal journey towards happiness during a one-year travel across 22 countries within southern Africa, southeast Asia, and south America, focusing on the first part of the trip – southern Africa. Autoethnography is a qualitative research method that involves the researcher reflecting on their personal experiences and cultural positionality in order to understand and analyse cultural phenomena (Bunyan, 2021). It combines elements of autobiography and ethnography, as the researcher uses their own experiences as a way to explore and understand the cultural context in which they participate (Hamilton, Smith and Worthington, 2008). Through the use of personal narrative and cultural analysis, I delve into the ways in which my own cultural background and societal expectations shaped my understanding of happiness. I also explore the ways in which immersing myself in a new culture and community impacted my pursuit of happiness and well-being. By reflecting on my own experiences and observations, I aim to shed light on the complexities of the pursuit of happiness and the potential for personal and cultural growth that can result from stepping outside of one's comfort zone. Through this autoethnographic lens, we hope to offer a unique and personal perspective on the pursuit of happiness, and to encourage readers to consider the cultural and individual factors that influence their own pursuit of this universal goal. We also reflect on how innovation and technology, essential to business, may not be as important to achieve happiness in certain contexts. This essay is a call for reflection on what truly matters in life.
