Abstract
Purpose
This study empirically examines the impact of climate change and agricultural research and development (R&D) as well as their interaction on agricultural productivity in 12 selected Asian and Pacific countries over the period of 1990–2018.
Design/methodology/approach
Various estimation methods for panel data, including Fixed Effects (FE), the Feasible Generalized Least Squares (FGLS) and two-step System Generalized Method of Moments (SGMM) were used.
Findings
Results show that both proxies of climate change – temperature and precipitation – have negative impacts on agricultural productivity. Notably, agricultural R&D investments not only increase agricultural productivity but also mitigate the detrimental impact of climate change proxied by temperature on agricultural productivity. Interestingly, climate change proxied by precipitation initially reduces agricultural productivity until a threshold of agricultural R&D beyond which precipitation increases agricultural productivity.
Practical implications
The findings imply useful policies to boost agricultural productivity by using R&D in the context of rising climate change in the vulnerable continent.
Originality/value
This study contributes to the literature in two ways. First, this study examines how climate change affects agricultural productivity in Asian and Pacific countries – those are most vulnerable to climate change. Second, this study assesses the role of R&D in improving agricultural productivity as well as its moderating effect in reducing the harmful impact of climate change on agricultural productivity.

Abstract
Purpose
Agriculture is the backbone of a country, contributing more than half of the sector of economy throughout the world. The need for precision agriculture is essential in evaluating the conditions of the crops with the aim of determining the proper selection of pesticides. The conventional method of pest detection fails to be stable and provides limited accuracy in the prediction. This paper aims to propose an automatic pest detection module for the accurate detection of pests using the hybrid optimization controlled deep learning model.
Design/methodology/approach
The paper proposes an advanced pest detection strategy based on deep learning strategy through wireless sensor network (WSN) in the agricultural fields. Initially, the WSN consisting of number of nodes and a sink are clustered as number of clusters. Each cluster comprises a cluster head (CH) and a number of nodes, where the CH involves in the transfer of data to the sink node of the WSN and the CH is selected using the fractional ant bee colony optimization (FABC) algorithm. The routing process is executed using the protruder optimization algorithm that helps in the transfer of image data to the sink node through the optimal CH. The sink node acts as the data aggregator and the collection of image data thus obtained acts as the input database to be processed to find the type of pest in the agricultural field. The image data is pre-processed to remove the artifacts present in the image and the pre-processed image is then subjected to feature extraction process, through which the significant local directional pattern, local binary pattern, local optimal-oriented pattern (LOOP) and local ternary pattern (LTP) features are extracted. The extracted features are then fed to the deep-convolutional neural network (CNN) in such a way to detect the type of pests in the agricultural field. The weights of the deep-CNN are tuned optimally using the proposed MFGHO optimization algorithm that is developed with the combined characteristics of navigating search agents and the swarming search agents.
Findings
The analysis using insect identification from habitus image Database based on the performance metrics, such as accuracy, specificity and sensitivity, reveals the effectiveness of the proposed MFGHO-based deep-CNN in detecting the pests in crops. The analysis proves that the proposed classifier using the FABC+protruder optimization-based data aggregation strategy obtains an accuracy of 94.3482%, sensitivity of 93.3247% and the specificity of 94.5263%, which is high as compared to the existing methods.
Originality/value
The proposed MFGHO optimization-based deep-CNN is used for the detection of pest in the crop fields to ensure the better selection of proper cost-effective pesticides for the crop fields in such a way to increase the production. The proposed MFGHO algorithm is developed with the integrated characteristic features of navigating search agents and the swarming search agents in such a way to facilitate the optimal tuning of the hyperparameters in the deep-CNN classifier for the detection of pests in the crop fields.

Abstract
The search for top executives is fraught with pitfalls. Understanding them will set the process off on a strong footing and maximize the chances of a sustainable hire. This chapter examines three aspects of the search dynamic: “stakeout,” “trust-building” and the search consultant’s “ambassador role.” We reveal nine important insights. Has digitization made headhunting any easier? We correct common misconceptions and reveal the difficulty of approaching top executives with role propositions, the building of trusted relationships with clients, and the ambassador role of the executive search consultant. We examine the need for empathy and deep discernment in reading candidates. We next go more deeply into the full search process: the selection of the search firm, the search itself, the presentation of the chosen candidate and onboarding. We reveal points of attention for clients and candidates that underpin best practice.
An earlier form of this chapter by the author was published in Dutch in “Bestemming Boardroom: over zoeken en gevonden worden” (Boom, Amsterdam, 2018).

Abstract
Purpose
This study aims to investigate the interplay between a proactive attitude towards disruptions – supply chain disruption orientation – and supply chain resilience, increasing our understanding of their influence on reducing the impact of supply chain disruptions within the B2B context.
Design/methodology/approach
As unexpected disruptions are closely related to a dynamic and changing perception of the environment, this research is framed under the dynamic capabilities lens, consistent with existing resilience literature. The authors used partial least squares-path modeling (PLS-PM) to empirically test the proposed research model using survey data from 216 firms.
Findings
Results show that a proactive approach to disruptions alone is insufficient in mitigating their negative impact. Instead, a firm’s disruption orientation plays a crucial role in boosting its resilience, which acts as a mediator, reducing the impact of disruptions.
Originality/value
This paper sheds light on the mechanisms by which firms can mitigate the effects of supply chain disruptions and offers insights into how certain capabilities are needed so that firms’ attitudes can effectively impact firm performance. This research thus suggests that dynamic capabilities, traditionally perceived as being enabled by other elements, act themselves as enablers. Consequently, they have the potential to translate strategic orientation or attitudes into tangible effects on performance, enriching our understanding of how firms combine their internal attitudes and capabilities to achieve sustained competitive advantage.

This study aims to increase knowledge of the ability of nutrition labels to guide consumer choices in real-life environments.
Abstract
Purpose
This study aims to increase knowledge of the ability of nutrition labels to guide consumer choices in real-life environments.
Design/methodology/approach
Food consumption and plate waste data were collected from two self-service restaurants (SSR) with different customer groups over six observation days: three control and three intervention (with nutrition labelling) periods. Study Group 1 consisted of vocational school students, mostly late adolescents (N = 1,710), and Group 2 consisted of spa hotel customers, mostly elderly (N = 1,807). In the experimental restaurants, the same food was served to the buffets during the control and intervention periods.
Findings
The nutrition label in the lunch buffet guides customers to eat fewer main foods and salads and to select healthier choices. Increased consumption of taste enhancers (salt and ketchup) was observed in the study restaurants after nutritional labelling. Nutrition labelling was associated with a reduction in plate waste among the elderly, whereas the opposite was observed among adolescents.
Originality/value
The results provide public policymakers and marketers with a better understanding of the effects of nutrition labelling on consumer behaviour. Future studies should further evaluate the effects of nutrition labelling on the overall quality of customer diets and the complex environmental, social, and psychological factors affecting food choices and plate waste accumulation in various study groups.

The study evaluates the role of institutional framework and macroeconomic instability on financial market development among emerging economies.
Abstract
Purpose
The study evaluates the role of institutional framework and macroeconomic instability on financial market development among emerging economies.
Design/methodology/approach
The study uses panel data compiled from 32 countries from the sub-region of Sub-Sahara Africa (SSA), covering the period starting from 1996 to 2019. Empirical analyses were carried out using the two-step system generalized method of moments (TS-GMM) statistical framework.
Findings
Reviewed results suggest that institutional quality, effective governance and corruption control have a significant positive impact on financial market development among economies in the sub-region. Further empirical estimates show that macroeconomic risk and macroeconomic uncertainty have significant adverse effects on financial market development. Additionally, reported empirical estimates suggest that an improved institutional framework has the potential to lessen the adverse effect of macroeconomic instability on financial market development among economies in the sub-region.
Originality/value
The uniqueness of this empirical inquiry compared to related studies in the present literature stems from the fact that studies employing similar empirical approaches on the subject matter for economies in the sub-region are rare. Additionally, the analysis pursued in this study employs critical variables whose impact on financial market performance in the sub-region has not been examined per our review. These variables include indexes such as macroeconomic risk and institutional quality, which are unique to this study based on their construction; these indexes are generated using a principal component analysis procedure with different underlying variables compared to what may be found in the literature.

Abstract
Purpose
The aim of this study is to discern the role of digital finance in driving rural industrial integration and revitalization. Specifically, it intends to shed light on how the deep development of digital finance can contribute to the optimization and transformation of the rural industrial structure. The research further explores the particular effects of this financial transformation in the central and western regions of China.
Design/methodology/approach
This research studies the influence of digital finance on rural industrial integration across 30 Chinese provinces from 2011 to 2020. Utilizing the entropy weight method, a comprehensive evaluation index system is established to gauge the level of rural industrial integration. A two-way fixed effects model, intermediary effect model, and threshold effect model are employed to decipher the relationship between digital finance and rural industrial integration.
Findings
Findings reveal a positive relationship between digital finance and rural industrial integration. A single threshold feature was identified: beyond a traditional finance development level, the marginal effect of digital finance on rural industrial integration increases. These effects are more noticeable in central and western regions.
Originality/value
Empirical outcomes contribute to policy discourse on rural digital finance, assisting policymakers in crafting effective strategies. Understanding the threshold of traditional finance development provides a new perspective on the potential of digital finance to drive rural industrial integration.

Abstract
Purpose
The purpose of the study is to examine factors influencing cash holding of firms during periods of crisis. In recent times, the level of cash holdings in firms has seen a steady rise across industries for diverse reasons. However, the need to study cash holding becomes even more compelling during geopolitical instability as it causes firms to hold greater cash reserves for precautionary reasons.
Design/methodology/approach
This paper systematically reviews literature from 1984 to 2024 by organising the findings thematically based on the relationship between corporate cash holdings (CCH) and firm performance in times of war. The paper used 47 research articles from the Scopus database and Google Scholar. Literature connected to CCH, firm performance and war times was explored. The title and abstract analysis were conducted using VOSviewer software. As a result, the predetermined body of literature was visualised, and six theme-based clusters were identified.
Findings
This paper systematically reviews empirical studies, categorising them into six theme-based groups. These clusters encompass CCH and Determinants, Optimal Cash Holding Levels, Cash Holding Adjustment Speed and Theory, Cash Holding and Firm Value, Cash Holding and Firm Performance, Cash Holding in the Context of the Ukraine War and the adaptive financial strategies of firms in response to economic conditions by using cash holding as a hedging instrument. Inflation prompts adjustments in cash-holding strategies at a macro level. During crises, lower interest rates lead to increased cash holdings. Various motives influence firms’ cash-to-assets ratios. According to the pecking order theory, geopolitical risk negatively affects cash holdings. Exposure to pandemics prompts an increase in cash reserves. War shocks have a profound impact on economies, markets and stability; hence, geographic diversification can reduce the need for precautionary cash. In times of uncertainty, the financial stress of firms can get elevated, and therefore, having a well-diversified geographical portfolio of a firm’s investments can aid in meeting any financially distressing situation.
Originality/value
The literature on CCH has been phenomenal. This paper attempts to structure the issues surrounding cash holding and firm performance in wartime, like the Ukraine war, using the VOSviewer software. This study endeavours to highlight the reasons for cash holding during crises and understand how cash holding affects firm performance. Finally, this paper also tries to comprehend whether cash holding helps as a hedging instrument in times of war.
