Market efficiency and price risk management of agricultural commodity prices in India
Authors: R.L. Manogna , Mishra Aswini Kumar 
Published: October 2021

PurposeMarket efficiency leads to transparent and fair price discovery of commodity markets, thus enhancing the value chain for competitive benefit. The purpose of this paper is to investigate the market efficiency of Indian agricultural commodities at spot, futures and mandi markets apart from exploring price risk management in these markets.Design/methodology/approachThis study uses Johansen co-integration, vector error correction model and granger causality for analyzing market efficiency of the nine most liquid agricultural commodities across three markets, namely, spot, futures and mandi. All these nine commodities are traded on National Commodity and Derivatives Exchange.FindingsThe statistical results indicate price discovery exists in the mandi market and spot market leading to futures prices. Mandi price returns are seen to negatively influence futures returns in the case of cotton seed, guar seed and spot returns in the case of jeera, coriander and chana. For castor seed, the three markets are seen to have no long run relationship. The results of Granger causality reveal short run relationship between all the three markets in the case of soybean seed and coriander. In these commodities, prices in all three markets are capable of predicting the prices in the other markets. For the case of cottonseed, Rape Mustard seed, jeera, guar seed, the results indicate unidirectional causality between the mandi markets and the other two markets.Research limitations/implicationsThese results shall facilitate policymakers to explore intervention through integrated agri-platform (IAP) in price discovery and market efficiency.Practical implicationsThe results of this study are useful in understanding the price discovery of mandi markets and its role in the spot and futures market. Agricultural commodities price discovery depends upon the integration of all these three markets. Introduction of IAP as described in the paper shall facilitate price risk management apart from improving the efficiency of price discovery.Originality/valueTo the best of the knowledge, this is the first study considering mandi, spot and futures prices in the price discovery process in India. In addition, this study found the role of mandi markets in serving the economic function of price discovery and price risk management. Hence, suggests for policy intervention for Indian agricultural commodities to manage price risk.

Published: October 2021

Purpose
Peer support has been identified as an important protective factor for mental health and overall well-being. The purpose of this study is to examine the feasibility of implementing an online peer support group and its impact on measures of well-being.

Design/methodology/approach
A mixed-methods randomized controlled trial design was used to examine the feasibility and impact of online peer support. Comparisons in well-being were made between the online peer support group and an in-person peer support group and control group. Participants were randomly assigned to a control group or either a six-week in-person or online peer support group. All participants completed an online survey measuring constructs of well-being pre- and post-condition. Additionally, qualitative data regarding the benefits of peer support and in particular the efficacy of the online format were collected from participants. Analysis of variance and post hoc tests determined significant differences within and between the groups.

Findings
Both the online and face-to-face peer support groups scored significantly higher on post-test measures of well-being than pre-test scores and control group scores. Qualitative narratives and significant quantitative findings supported the feasibility of peer support offered online. Post-condition outcomes showed that online peer support is as effective as in-person peer support for improving well-being.

Originality/value
To the best of the authors’ knowledge, this study is the first of its kind to compare online and in-person peer support programs for students in higher education. The results have direct implications for higher education students and practitioners, especially at times when face-to-face support is not feasible.
Do sensory reviews make more sense? The mediation of objective perception in online review helpfulness
Authors: Lopez Alberto , Garza Ricardo 
Published: October 2021

PurposeDo consumers rate reviews describing other consumers' sensory experience of a product (touch, smell, sight, hear and taste) as helpful or do they rate reviews describing more practical properties (product performance and characteristics/features) as more helpful? What is the effect of review helpfulness on purchase intention? Furthermore, why do consumers perceive sensory and non-sensory reviews differently? This study answers these questions.Design/methodology/approachThe authors analyze 447,792 Amazon reviews and perform a topic modeling analysis to extract the main topics that consumers express in their reviews. Then, the topics were used as regressors to predict the number of consumers who found the review helpful. Finally, a lab experiment was conducted to replicate the results in a more controlled environment to test the serial mediation effect.FindingsContrary to the overwhelming evidence supporting the positive effects of sensory elicitation in marketing, this study shows that sensory reviews are less likely to be helpful than non-sensory reviews. Moreover, a key reason why sensory reviews are less effective is that they decrease the objective perception of the review, a less objective review then decreases the level of helpfulness, which decreases purchase intention.Originality/valueThis study contributes to the interactive marketing field by investigating customer behavior and interactivity in online shopping sites and to the sensory marketing literature by identifying a boundary condition, the authors’ data suggest that sensory elicitations might not be processed positively by consumers when they are not directly experienced, but instead communicated by another consumer. Moreover, this study indicates how companies can encourage consumers to share more effective and helpful reviews.
Balancing risk and trust for strategic alliance formation decisions
Authors: Collier Zachary A. , Wood Matthew D. , Henderson Dale A. 
Published: October 2021

PurposeTrust entails the assumption of risk by the trustor to the extent that the trustee may act in a manner unaligned with the trustor's interests. Before a strategic alliance is formed, each firm formulates a subjective assessment regarding whether the other firm will behave in a trustworthy manner and not act opportunistically. To inform this partner analysis and selection process, the authors leverage the concept of value of information to quantify the benefit of information gathering activities on the trustworthiness of a potential trustee.Design/methodology/approachIn this paper, the authors develop a decision model that explicitly operationalizes trust as the subjective probability that a trustee will act in a trustworthy manner. The authors integrate the concept of value of information related to information gathering activities, which would inform a trustor about a trustee's trustworthiness.FindingsTrust inherently involves some degree of risk, and the authors find that there is practical value in carrying out information gathering activities to facilitate the partner analysis process. The authors present a list of trustworthiness indicators, along with a scoring sheet, to facilitate learning more about a potential strategic alliance partner.Originality/valueThe need for a quantitative model that can support risk-based strategic alliance decision-making for partner analysis represents a research gap in the literature. The modeling of strategic alliance partner analysis decisions from a value of information (VOI) perspective adds a contribution to the trust literature.

Authors: Jeon Junwoo , Gulay Emrah , Duru Okan 
Published: October 2021

PurposeThis research analyzes the cycle of the dry bulk shipping market (DBSM) as a representative of spot and period charter rates in dry bulk shipping to develop strategies for investment timing (i.e. asset play) and fleet trading (chartering strategy).Design/methodology/approachSpectral analysis is a numerical approach to extract significant cyclicality, which may be utilized to develop trading strategies. Instead of working with a single dataset (univariate), a system approach can be utilized to observe a significant shipping market cycle in its multi-variate circumstance. In this paper, a system dynamics design is employed to extract cyclicality in the DBSM in its particular industrial environment. The system dynamic design has competitive forecasting accuracy relative to univariate time series models and artificial neural networks (ANNs) in terms of forecasting outcomes.FindingsThe results show that the system dynamic design has a better forecasting performance according to three evaluation metrics, mean absolute scale error (MASE), root mean square error (RMSE) and mean absolute percentage error (MAPE).Originality/valueCyclical analysis is a significantly useful instrument for shipping asset management, particularly in market entry–exit operations. This paper investigated the cyclical nature of the dry bulk shipping business and estimated significant business cycle periodicity at around 4.5-year frequency (i.e. the Kitchin cycle).

Dialogic storying: a narrative research methodology in English language education
Authors: Dhungana Siddhartha 
Published: October 2021

PurposeThe article aims at analyzing narratives discourses to project dialogic storying as relevant in a mode of narrative research in English language education.Design/methodology/approachAs an English language teacher and researcher, the author adopts narrative analysis as the research method for doctoral study, so this article delves into narrative research methods, especially in the context of English language education. The author found various existing notions on narrative research from Clandinin and Connelly (2000) and Barkhuizen et al. (2014), who contend that narrative is a mode of processing experiences and events in the form of a story. The author corroborated various notions on narrative research in English language education as an argument that narratives can be a strong data source in English language educational research. Since it has been a research focus for English language educators, the author explored seven dissertations that were submitted to a Nepalese university in 2017, 2018 and 2019.FindingsThe article aims at analyzing narratives discourses to project dialogic storying as relevant in a mode of narrative research in English language education. While examining the dissertations, the author found that the subjective and ideological exploration of narratives is in practice; however, they need further in-depth analysis under a specific framing. The author argues that the concept of dialogic storying can be strong narrative research in English language education.Research limitations/implicationsIt has examined prospective applications of the dialogic storying process using dissertations submitted to a University in Nepal. In terms of conceptual discussions on narratives and narrative analysis, it is more interpretive.Practical implicationsIt provides an initial framing to get into narrative research in English language education. It allows academics to go further into subjective and ideological inquiries in order to discuss more categorical elements in narrative research.Originality/valueIt is a more thematic and interpretive discussion so it discusses existing and appropriate practices in narrative research methods to defend the dialogic storying approach. It has not counter argued the existing knowledge; however, it provides insights to clarify dialogic storying as a research approach.
Contradicting challenges: the complexity of documenting personal information in a regulatory environment
Authors: Haraldsdottir Ragna Kemp , Gunnlaugsdottir Johanna 
Published: October 2021

Purpose
Many organizations are challenged by different and, perhaps, opposite, registration and protection obligations of information regarding their employees. The purpose of this paper is to explore how organizations balance the registration obligations of the Icelandic equal pay standard (EPS) and the protection requirements of the general data protection regulation (GDPR). It aims to raise awareness of how information professionals can ensure that documentation on the education and skills of employees is authentic, traceable and secure.

Design/methodology/approach
The analytical framework covered multiple-cases and semi-structured interviews with various professionals and comprehensive documentary analysis.

Findings
The findings indicate that the organizations were not properly prepared for the implementation of the EPS and were hesitant regarding further registration of personal information due to GDPR. Documentary analysis also revealed critical attitudes towards the legal endorsement of the standard and its potential success.

Originality/value
There is a lack of studies explaining the juxtaposition of information and records management and the legal and regulatory environment. This paper provides a unique description of how information and recordkeeping practices function with the requirements of the EPS whilst complying with GDPR. The results could bring valuable opportunities for the information profession regarding the development, implementation, administration and maintenance of documentary evidence regarding the requirements of international and national standards and legislations and advance their collaboration with other professionals in the management of information.
The adoption of integrated reporting by state-owned enterprises (SOEs) – an international comparison
Authors: Ackers Barry , Adebayo Adeyemi 
Published: October 2021

Purpose
This paper aims to establish the extent to which South African state-owned entities (SOEs), where integrated reporting is a quasi-mandatory reporting requirement, have incorporated the principles of the international integrated reporting framework. These identified South African SOE reporting practices are compared with the ‘integrated reporting’ related disclosures of SOEs in selected countries, where integrated reporting remains voluntary.

Design/methodology/approach
This paper deploys a qualitative research approach, to thematically analyse the content of publicly available annual or integrated reports of South Africa SOEs, as the primary country of analysis, with those of their counterparts in five purposively selected countries. The relative scores for the SOEs of each country is calculated using a disclosure index derived from the international integrated reporting framework principles.

Findings
The paper found that despite being a quasi-mandatory reporting requirement, not all South African SOEs complied with all the international integrated reporting framework principles. Accepting the assertion that integrated reporting enhances organisational transparency and accountability, the accountability disclosure practices of South African SOEs appear more comprehensive than their counterparts in other countries.

Originality/value
Extant research into integrated reporting has primarily focussed on the profit-seeking private sector, with limited research into its applicability in the public sector. This paper attempts to address this paucity by examining aspects of integrated reporting by South African SOEs, which are then compared to accountability reporting practices in other countries.
Promising strategies to control persistent enemies: Some new technologies to combat biofilm in the food industry—A review
Authors: Mevo Senakpon Isaïe Ulrich , Ashrafudoulla Md. , Furkanur Rahaman Mizan Md. , Park Si Hong , Ha Sang‐Do 
Published: October 2021

AbstractBiofilm is an advanced form of protection that allows bacterial cells to withstand adverse environmental conditions. The complex structure of biofilm results from genetic‐related mechanisms besides other factors such as bacterial morphology or substratum properties. Inhibition of biofilm formation of harmful bacteria (spoilage and pathogenic bacteria) is a critical task in the food industry because of the enhanced resistance of biofilm bacteria to stress, such as cleaning and disinfection methods traditionally used in food processing plants, and the increased food safety risks threatening consumer health caused by recurrent contamination and rapid deterioration of food by biofilm cells. Therefore, it is urgent to find methods and strategies for effectively combating bacterial biofilm formation and eradicating mature biofilms. Innovative and promising approaches to control bacteria and their biofilms are emerging. These new approaches range from methods based on natural ingredients to the use of nanoparticles. This literature review aims to describe the efficacy of these strategies and provide an overview of recent promising biofilm control technologies in the food processing sector.
Small cell transformation in crizotinib‐resistantROS1‐rearranged non‐small cell lung cancer with retention ofROS1fusion: A case report
Authors: Wu Chi‐Hao , Su Po‐Lan , Hsu Che‐Wei , Chu Chang‐Yao , Lin Chien‐Chung 
Published: October 2021

AbstractC‐ros oncogene 1 receptor tyrosine kinase (ROS1) rearrangement has been detected in patients with advanced non‐small cell lung cancer (NSCLC). Although ROS1 tyrosine kinase inhibitors (TKIs) provide a survival benefit for patients with ROS1‐rearranged advanced NSCLC, subsequent therapy remains limited. Small cell transformation is an important mechanism of drug resistance in epidermal growth factor receptor‐mutant NSCLC. However, its significance in mediating ROS1 resistance has not been determined yet. Here, we present the case of a 63‐year‐old man with ROS1‐rearranged advanced NSCLC who had disease progression with small cell transformation of the mediastinal lymph node after 8 months of treatment with crizotinib. More importantly, fluorescence in situ hybridization of post‐progression tumor biopsy demonstrated retention of ROS1 rearrangement. Tissue biopsy remains indispensable for patients who acquire resistance to ROS1 TKIs.
The Impact of Knowledge Transfer on Investment in Knowledge Creation in Firms†‡
Authors: Tafkov Ivo , Towry Kristy , Zhou Flora Hailan 
Published: October 2021

ABSTRACTKnowledge is key to success in the modern business landscape. Firms invest billions of dollars every year in knowledge management systems, which commonly use artificial intelligence to allow within‐firm knowledge transfer to occur automatically. Despite this investment, these systems often fall short of producing expected results. Using psychology theory on goal dilution, we argue that a potential cause of the failure is that the prospect of knowledge transfer has a negative effect on knowledge creation. We further propose a mechanism to mitigate that effect. Specifically, we predict that the negative effect of knowledge transfer on knowledge creation will be mitigated when the linkages among firm‐ and unit‐level goals are communicated. We conduct an experiment and find that while, as predicted, the prospect of knowledge transfer has a negative effect on knowledge creation when the linkages among firm‐ and unit‐level goals are not communicated, it has the predicted positive effect when the linkages among firm‐ and unit‐level goals are communicated due to increased goal congruence. Additional analyses provide support for our underlying theories. Our results suggest that firms can adopt and communicate strategic performance measurement systems to improve the knowledge creation in a firm.
Enhancing mask activity in dopaminergic neurons extends lifespan in flies
Authors: Tian Xiaolin 
Published: October 2021

AbstractDopaminergic neurons (DANs) are essential modulators for brain functions involving memory formation, reward processing, and decision‐making. Here I demonstrate a novel and important function of the DANs in regulating aging and longevity. Overexpressing the putative scaffolding protein Mask in two small groups of DANs in flies can significantly extend the lifespan in flies and sustain adult locomotor and fecundity at old ages. This Mask‐induced beneficial effect requires dopaminergic transmission but cannot be recapitulated by elevating dopamine production alone in the DANs. Independent activation of Gαsin the same two groups of DANs via the drug‐inducible DREADD system also extends fly lifespan, further indicating the connection of specific DANs to aging control. The Mask‐induced lifespan extension appears to depend on the function of Mask to regulate microtubule (MT) stability. A structure–function analysis demonstrated that the ankyrin repeats domain in the Mask protein is both necessary for regulating MT stability (when expressed in muscles and motor neurons) and sufficient to prolong longevity (when expressed in the two groups of DANs). Furthermore, DAN‐specific overexpression of Unc‐104 or knockdown of p150Glued, two independent interventions previously shown to impact MT dynamics, also extends lifespan in flies. Together, these data demonstrated a novel DANs‐dependent mechanism that, upon the tuning of their MT dynamics, modulates systemic aging and longevity in flies.
