2021 Early Career Researcher award winner presented her topic 'Business strategy in the age of AI: Where artificial intelligence can confer a competitive advantage'.
This public talk is designed for business leaders and will outline how New Zealand organisations can survive and thrive amidst AI-driven change.
Artificial intelligence (AI) and technological advancements are driving rapid change. World-leading organisations now employ AI in most parts of their value chain to reduce costs and improve decision-making, processes, products and services. New Zealand organisations that do not have an AI strategy and are slow to adopt AI, may quickly become obsolete and irrelevant. In this seminar, Dr Williamson outlines the opportunities that AI presents for businesses, and how leaders can commence harnessing the value of AI.
This one-hour seminar is designed for managers and business leaders. By the end of the hour, attendees should have an understanding of:
- How AI can (and cannot) help businesses today.
- Where to begin with an AI-driven strategy

is a senior lecturer in Supply Chain Management at the 糖心Vlog. Her research focuses on logistics operations in the aftermath of a disaster.
Natural hazards disrupt pre-existing transport networks and the deliveries of goods needed by businesses and individuals. When the infrastructure damage is significant, re-establishing critical connections may not be an option in the short term. To ensure the continuity of their supply chains, businesses need to swiftly adjust their freight operations across routes and transport modes.
Since New Zealand is prone to natural hazards, supply chain disruptions are to be expected. It is not a question of if, but when. However, little is known about the ability of the New Zealand freight system to adapt and recover when parts of the transport network fail.
On the 18th November 2021, C茅cile presented her recent qualitative research work investigating the freight disruptions caused by the and the subsequent implementation of alternative transport arrangements.
The workshop was coordinated by Shane Stuart, Innovation Manager Bay of Plenty, which is a joint position between the University and Priority One (the economic development organisation for Tauranga and the Western Bay of Plenty). Those who attended were most relevant to people who are active in research relating to the horticulture and aquaculture sectors, and with Bay of Plenty stakeholders.
The proposed unit has the working title of 鈥楤lue/Green Nexus鈥� and would be focussed on research and related activity supporting high value solutions in horticulture and aquaculture industries, environments and value chains.
is a Senior Lecturer in Supply Chain Management at Waikato Management School and her research focuses on the resilience of national and global supply chain systems and how these systems affect quality of life and equity within communities.
To create industry-relevant graduates, it is essential to connect our teaching practice to real life scenarios. Using case studies is one way of doing that. There is no shortage of case study material out there, but there are at least two benefits in publishing and using case studies that have been homegrown in the Waikato Management School.
Firstly, as educators we are more connected to the cases we were involved in and can teach with more authority from that position. We also have the opportunity to customise case studies that achieve our specific learning objectives instead of retrofitting someone else's case study.
Secondly, publishing case studies on widely accessed platforms is a fantastic way to market our school's connection with industry.
In this session, Dr Trent presented the process she and Dr C茅cile L'Hermitte have gone through to create and use a homegrown case study that spans both supply chain strategy and humanitarian logistics. So far, they have used the case study in an MBA paper and are now working on a draft to send to SAGE Business Cases for publication.
On Wednesday, 29 September 2021, Professor Paul Griffiths - EM Normandie Business School gave an online presentation of the Principles for Responsible Banking (PRB) showcasing how blockchain could contribute to achieving their implementation.
Main findings shed light on the importance of transparency, trust and the involvement of all stakeholders for the implementation of Blockchain solutions within banks. However, some barriers are raised such as the energy consumption of Blockchain, the misunderstanding and need for education on this disruptive technology, and the quality of data.
On the 5th August 2021, commemorating his Early Career Researcher award, Yang Hu gave public lecture on his current research titled 鈥�Strange Times in Financial Markets: Covid-19, Cryptocurrencies and Negative Oil Futures Prices鈥�.
As part of a research team, Dr Hu has examined the role of cryptocurrency as a safe-haven during the Covid-19 pandemic, when large capital value cryptocurrencies acted as a store of value during this period of exceptional financial market stress. More recently, the research team also investigated the behaviour of Elon Musk in relation to the cryptocurrency Dogecoin. Their research shows that Elon Musk鈥檚 tweets significantly affected the stability and volatility of Dogecoin.
The 糖心Vlog hosted an inspirational evening of discussion around the theme of sustainable citizenship, led by two of our leading professors, Debashish Munshi (Waikato Management School) and Priya Kurian (School of Social Sciences).
Featuring their latest books , ' (2021), and ' (2019), the evening re-imagined public relations as an "instrument of sustainable citizenship" by outlining how resistance movements seek to change the status quo of a world that is increasingly defined by exploitation, overconsumption, sectarianism, and faux nationalism.
Following the talk, an interactive panel discussion featuring guest speakers Heather Claycomb, director of the public relations firm HMC Communications, Sandy Morrison, Acting Dean of the Faculty of M膩ori and Indigenous Studies, Jennifer Nickel, an elected Waikato Regional Councillor, who chairs the council's climate action committee, and Kemi Hughes, who is completing her PhD in climate change law and sustainable development.
On the 19 November 2020, Amanda J. Williamson presented her latest research in AI which can help illuminate change in meaning and perceptions. In this presentation, Amanda introduced an AI approach (word embeddings) that captures meaning in large volumes of text data, and shared preliminary results on how 鈥渆ntrepreneurship鈥� has changed over 20 years in five countries (NZ, USA, CA, AU, IE, UK). These results indicate that gender bias in language is reducing in relation to entrepreneurship. Moreover, entrepreneurship鈥檚 association with other words is shifting over time. Entrepreneurship is moving away from government and complexity, and towards social words and crowdfunding. Finally, the language surrounding entrepreneurship differs between countries

On 6th November 2019, WMS Senior Lecturer in Digital Business, Dr Gohar Khan, demonstrated how product sales are influenced by the network effect of the 鈥渓ike鈥� button on social media and why the Network Externality Approach is such a valuable marketing phenomenon.
Khan used his own published paperback to test his hypothesis and closely monitored brand exposure and sales return over a three-month period. His study found that discrete advertising lead to lower social and network gains, but higher monetary returns and social advertising produce higher social and network capital, but low monetary returns.
Between 15 鈥� 31 October 2019, Adjunct Professor Martin Wetzels visited the 糖心Vlog and facilitated the following programmes during his stay:

- A Two-day Training Workshop 鈥�R-Workshop: Step-by-step鈥�. The main objective was introducing participants to key data analysis techniques and forming an essential part of a PhD training, several management positions and research-oriented jobs
Discussions were held around the impact of of digital disruption on the marketing narrative, using insights obtained from big data analytics. He will also explain what this means for both practitioners and academics alike.
鈥淲hat kind of data is out there, and how can we best analyse it? It鈥檚 exciting to see how people can take text, video, pictures and voice data and combine it into a comprehensive dashboard of what is going on," says Dr Wetzels.
Customers' influence is growing, but they are also giving away a lot of valuable information about themselves. Marketing practitioners need powerful new data mining and analytics tools to provide them with fresh, actionable insights into user generated content
Professor Wetzels outcomes were well received
WMS welcomed world-renowned marketing expert Professor Ajay Kohli in September 2019.
Dr Kohli鈥� began his visit with a one-hour Practitioner Talk 鈥楥ustomer Centricity in a Digital World鈥� at the 糖心Vlog鈥檚 Management School. This work has made Dr Kohli one of the worlds most cited experts in marketing research, as well as being among the world鈥檚 100 most cited authors in business and economics.
Following the Practitioner Talk Dr Kohli conducted a full-day workshop, which was attended by staff and students from across New Zealand. The workshop comprised of two parts namely an interactive lecture-discussion and 鈥榣earn by doing鈥�.
Dr Kohli鈥檚 award-winning research has revolutionised the field of marketing by elevating the importance of customer orientation from sales tactic to the boardroom level, ensuring that customers鈥� needs are placed at the very heart of an organisation鈥檚 brand and strategy.
On the 28th August Suzette, Fiona and Heather showcased three experiential learning exercises designed to help students learn and reflect on some of the techniques required for managing their careers.
One of the exercises required attendees to write down their definition of 鈥榗areer鈥� and then draw an illustration on how they perceived their career. Attendees then discussed their career definitions and considered how their illustrations depict family and community responsibility, potential career breaks, interest and skill development and leisure time activities.
These learnings highlight that good career management practice is a holistic process that cannot be achieved through ad-hoc, one-off interventions and it was only after redeveloping the course HRM students could gain better understanding practice, management and impact of career development.
On the 22nd July, Dr Geeta Duppati examined the effects of institutional investor ownership (IIO) on innovation, and provided evidence from OECD and emerging nations.
This study extends prior literature by investigating two interrelated research questions. Dr Duppati first investigated whether IIO influences firm innovation and second, whether the stage of economic development influenced the effects of IIO on innovation. The results suggest that monitoring by institutional investors can act as an important mechanism to promote firm innovation
On 4th June, Dr Amanda J Williamson gave a compelling presentation on why innovative behaviour at the individual level is critical for entrepreneurship and innovation, yet little is known about why and when an individual is more (or less) innovative.
In this presentation Dr Williamson elucidated the interesting yet oft-overlooked role that sleep has on innovative behaviour. Empirical research was presented which examined this relationship. The findings of which illustrate that entrepreneurs鈥� day-level innovative behavior is susceptible to significant fluctuation and that sleep as a resource renewal activity plays a key role in influencing entrepreneurs' innovative behaviours.

On April 9 2019, Dr Nirosha Hewa Wellalage gave a seminar presentation on the Effect of Petty Corruption on Firm-Level Innovation of Micro, Small and Medium Enterprises (MSMEs). Her abstract proposes bribery is a rational strategic response of micro-, small and medium enterprise innovators, compensating for the lack of kinship or political affiliations, and hedging against political risk.
Larger corporations exploit political affiliations; smaller firms use bribery at the level of lower officials, compensating for lack of property rights, rule of law and an effective judiciary. Analysis of World Bank Surveys, for South American countries, using propensity score matching indicates the determinants of the corruption鈥搃nnovation relationship has a positive correlation between bribery and innovation. Although the corruption is less damaging, it is a pervasive obstacle to economic development. Strong regulations can overcome this obstacle, as corruption only works in weak institutional structures.
On 6 March 2019, four experts were invited to speak, on the subject of wellbeing from their chosen perspective. Following each of the invited presentations, small group discussions were held during which questions and issues were raised. This paper first sets out the key points of the presentations, and the group reactions.
The purpose of the day was to bring together a diverse group of thought leaders to begin to identify areas of expertise, concern and interest that might be picked up and further explored.
