AbstractThe cerebellum regulates nonmotor behavior, but the routes by which it exerts its influence are not well characterized. Here we report a necessary role for the posterior cerebellum in guiding a reversal learning task, acting through a network of diencephalic and neocortical structures. After chemogenetic inhibition of Purkinje cells in lobule VI or crus I, mice could learn a water Y-maze task but were impaired in their ability to reverse their initial choice. To map targets of perturbation, we imaged c-Fos activation in cleared whole brains using light-sheet microscopy. Reversal learning activated diencephalic regions and associative neocortical regions. Distinctive subsets of structures were altered by perturbation of lobule VI (including thalamus and habenula) and crus I (including hypothalamus and prelimbic/orbital cortex), and both perturbations influenced anterior cingulate and infralimbic cortex. To identify functional networks, we used correlated variation in c-Fos activation within each test group. Lobule VI inactivation weakened within-thalamus correlations, while crus I inactivation divided neocortical activity into well-separated sensorimotor and associative subnetworks. In both groups, high-throughput automated analysis of complex whole-body movement revealed deficiencies in across-day adaptation to an open field environment. Neither perturbation affected gait, within-day open-field adaptation, or location preference. Taken together, these experiments reveal brainwide systems for cerebellar influence that can affect multiple flexible responses.Significance statementThe cerebellum, a part of all vertebrate brains, provides feedback to the rest of the brain on a split-second basis in response to unexpected events. The consequent changes can range from minute adjustments in movement to broad changes in behavior. In mice, we investigated cerebellar regions that help guide flexible behavior. Inactivation of these regions prevented mice from responding flexibly to a changing Y-shaped maze. We used light-sheet microscopy of c-fos protein expression to map brainwide effects of different stages of learning and cerebellar inactivation. Inactivation caused changes in thalamocortical activity that were similar in pattern, but opposite in sign, from normal learning. Lobule VI inactivation weakened thalamic functional networks, while crus I inactivation divided sensorimotor from associative neocortical networks. The same inactivation also impaired multiday adaptation to an open arena, as tracked using machine vision. Our work shows how the cerebellum’s influence over flexible response can be mediated by a widespread brain network.

Impact of COVID-19 pandemic upon fashion consumer behavior: focus on mass and luxury products
Authors: Pang Wonbae , Ko Jisu , Kim Sang Jin , Ko Eunju 
Published: December 2021

PurposeThe COVID-19 pandemic has caused a decline in overall consumption, but luxury sales within offline department stores rose significantly. This study identifies changes in the market environment variable (i.e. pandemics) and their impact on clothing consumption behavior. Moreover, it examines consumer behavior characteristics and provides implications for future fashion marketing and merchandising strategies.Design/methodology/approachThis study analyzed post-pandemic consumption trends by obtaining luxury brand sales data from the Korea National Statistical Office and department stores. Moreover, it investigated luxury consumption fluctuation after the pandemic and statistically analyzed the characteristics of luxury consumers by customer level (CL) that affected sales.FindingsThe results of the study showed that offline (online) clothing consumption at mass markets has decreased (increased) since the pandemic, whereas sales of luxury fashion brands at offline department stores have grown. Moreover, the in-depth analysis showed a significant sales decline (increase) for clothing-centered (leather-centered) luxury brands.Practical implicationsIf such a trend in luxury brand consumption continues, current polarization is expected to be maintained. Therefore, the study’s findings can be used as basic data in strengthening luxury brands and planning products.Originality/valueThis is the first work to undertake a comparative study of fashion consumer behavior, before and after the pandemic, involving the mass and luxury markets in South Korea.
Value-relevance of reported changes in fair values and measurement-related fair value disclosures: evidence from the Australian real estate industry
Authors: Sangchan Pinprapa , Bhuiyan Md. Borhan Uddin , Habib Ahsan 
Published: December 2021

PurposeThe paper aims to investigate the value-relevance of changes in fair values of investment property reported under International Accounting Standards (IAS) 40 and International Financial Reporting Standards (IFRS) 13.Design/methodology/approachMultivariate regression models are used to regress cumulative market-adjusted stock returns of real estate firms on changes in fair values, along with control variables and corporate governance variables, in order to examine the research question.FindingsUsing hand-collected data from the Australian Real Estate Industry (AREI), the authors find that changes in fair values of investment property are value-relevant for equity investors. The authors further find that using unobservable inputs in an active market (Level 3 inputs) does not diminish the information content of fair values. The authors document that properties valued exclusively by directors have a significantly reduced value-relevance, whereas property valuations made collectively by both directors and independent valuers have superior value-relevance, possibly owing to the combination of inside knowledge and externally imposed monitoring. Collectively, the findings suggest that in the real estate industry, where unobservable inputs are commonly used to determine fair values of properties, the fair values determined subjectively are perceived to be sufficiently informative and relevant.Research limitations/implicationsThe authors' findings have important implications for accounting standard-setters in considering whether an external valuation should be required and whether the extensive measurement-related fair value disclosure requirements are useful.Originality/valueThe study extends previous archival evidence and complements prior commentaries on experimental and analytical work in the Australian regulatory environment.
Non-GAAP measure disclosure and insider trading incentives in high-tech IPO firms
Authors: BC Bishal , Liu Bo 
Published: December 2021

Purpose
This paper aims to investigate whether the non-generally accepted accounting principles (GAAP) performance measures (NGMs) disclosure by high-tech initial public offering (IPO) firms signal firms’ efforts to maintain relatively high stock price levels before the expiration of the lock-up period to benefit insider selling.

Design/methodology/approach
The authors perform ordinary least squares and logit regressions using financial statement data and hand collected data on NGM disclosures for high-tech firms during the IPO process.

Findings
The authors find that the top executives of high-tech IPO firms with NGM disclosures are significantly more likely to sell and sell significantly more insider shares at the lock-up expiration than those of high-tech IPO firms without NGM disclosures. At the same time, while high-tech NGM firms have stock returns similar to their counterparts without NGMs for the period before the lock-up expiration, their stock returns are substantially lower after insider selling following the lock-up expiration.

Practical implications
By documenting the negative association between NGM disclosures and post-lockup expiration stock performance, the study highlights managerial deliberate optimism about the firm’s prospects which may not materialize. Hence, investors should take the NGM disclosures with a grain of salt.

Originality/value
This paper fills a notable void in the non-GAAP reporting literature by documenting a statistically and economically significant positive association between managerial equity trading incentives and NGM disclosures by high-tech IPO firms.
Cooperatives' performance relative to investor-owned firms: a non-distorted approach for the wine sector
Authors: D'Amato Antonio , Festa Giuseppe , Dhir Amandeep , Rossi Matteo 
Published: December 2021

PurposeThis study aims to investigate whether significant performance differences between cooperatives and investor-owned firms (IOFs) may exist.Design/methodology/approachBased on data from a sample of Italian wine firms for the period from 2009 to 2018, an adjusted measure of performance called earnings before interests, taxes, depreciations and amortizations gross the raw materials cost was adopted to consider the different objectives of cooperatives relative to those of IOFs.FindingsEmpirical evidence shows that in the context under analysis, cooperatives have performed better than IOFs.Originality/valueDespite the theoretical literature suggesting that the cooperative form of organizations suffers from many weaknesses, these results highlight that cooperatives operating in the wine sector are at least as economically efficient as other organizations, and more specifically, they perform better than for-profit firms. Consequent implications for theory and practice are discussed.

Authors: Okuonghae Omorodion , Achugbue Edwin Iroroeavwo 
Published: December 2021

Purpose
The continuous advancement in technology has disrupted practices in many sectors, including education. Thus, this study aims to examine digital librarianship practice and open access technology use for sustainable development in Nigeria.

Design/methodology/approach
The survey type of descriptive research design was adopted in this study while the population of the study comprised librarians in universities in Delta State. A total of 38 randomly selected librarians from four universities in Delta State were used for this study, and the data collected were analysed using descriptive statistics.

Findings
This study revealed that the level of digital librarianship practice in university libraries in Delta State for sustainable development is low; just as social media tools, open source integrated library systems and Google Cloud Platforms are the most commonly used open access technologies in the libraries. Furthermore, this study showed that perennial factors such as poor funding of education, inadequate quality educational infrastructure, mismanagement of education fund among others are hindrance to sustainable development in the country’s educational sector.

Research limitations/implications
This study is limited in its use of only one state (out of 36 states and the Federal Capital Territory, Abuja) in Nigeria for this research. Also, social desirability bias on the part of the respondents could have influenced the pattern in which the respondents reacted to items in section D.

Practical implications
This study has practical implications for the sensitization and training of librarians towards leveraging on the various open access technologies in delivering effective library and information services required in the Fourth Industrial revolution.

Originality/value
This study seeks to pioneer a new area of focus by examining digital librarianship practice and open access technology use as enablers of sustainable development.
Unity lost. Negotiating the ancient roots of Pedagogy in Sweden, 1865–1971
Authors: Hammar Isak , Östh Gustafsson Hampus 
Published: December 2021

PurposeThe purpose of this article is to investigate attempts to safeguard classical humanism in secondary schools by appealing to a cultural-historical link with Antiquity, voiced in the face of educational reforms in Sweden between 1865 and 1971.Design/methodology/approachBy focusing on the content of the pedagogical journal Pedagogisk Tidskrift, the article highlights a number of examples of how an ancient historical lineage was evoked and how historical knowledge was mobilized and contested in various ways.FindingsThe article argues that the enduring negotiation over the educational need to maintain a strong link with the ancient past was strained due to increasing scholarly specialization and thus entangled in competing views on reform and what was deemed “traditional” or “modern”.Originality/valueFrom a larger perspective, the conflict over the role of Antiquity in Swedish secondary schools reveals a trajectory for the history of education as part of and later apart from a general history of the humanities. Classical history originally served as a common past from which Swedish culture and education developed, but later lost this integrating function within the burgeoning discipline of Pedagogy. The findings demonstrate the value of bringing the newly (re)formed history of humanities and history of education closer together.
Youth high unemployment/unemployability in South Africa: the unemployed graduates' perspectives
Authors: Mseleku Zethembe 
Published: December 2021

PurposeThe purpose of this paper is to explore youth graduate unemployment and unemployability as a development problem in South Africa.Design/methodology/approachThis exploratory study applied a qualitative research method to elicit the perspectives of youth graduates regarding their unemployment and unemployability. A total of 30 face-to-face semi-structured interviews were conducted with unemployed youth who recently graduated from five South African universities.FindingsThe results indicate that, as youth graduate unemployment increases in South Africa, graduates become hopeless in terms of securing employment. The participants attributed their unemployment to multidimensional factors that include limited demand in the labour market, skills mismatch and lack of work experience.Research limitations/implicationsThis research exclusively focused on graduates from five South African universities; hence, the results of this small qualitative study cannot be generalised to the entire South African population. However, this paper offers important insights that may form the foundation for a nationwide study on a related topic.Originality/valueThis paper presents important insights that influence policy makers, government and other relevant stakeholders to develop alternative solutions to youth graduate unemployment. This paper recommends that government should play a critical role in bridging the gap between higher education and industry in order to address youth graduate unemployment. It also calls for a more cooperative effort between government, higher learning institutions and employers in order to create job opportunities for youth graduates in South Africa.
Preparing supply chain for the next disruption beyond COVID-19: managerial antecedents of supply chain resilience
Authors: Nikookar Ethan , Yanadori Yoshio 
Published: December 2021

PurposeCOVID-19 once again showed the importance of building resilience in supply chains. Extant research on supply chain resilience management has successfully identified a set of organizational antecedents that contribute to supply chain resilience. However, little is known about the mechanisms by which these antecedents are developed within a firm. Drawing on the dynamic managerial capabilities theory, the current study aims to investigate the critical role that supply chain managers play in developing the organizational antecedents. Specifically, this study shows that supply chain managers' social capital, human capital and cognition are instrumental to the development of three organizational supply chain resilience antecedents: visibility, responsiveness and flexibility, which subsequently enhance the firm's supply chain resilience.Design/methodology/approachThe authors employ survey data collected from 598 manufacturing firms in Australia, and Hayes and Preacher's (2014) parallel multiple mediator model to empirically test the hypotheses.FindingsThe findings of the study establish that supply chain managers' social capital, human capital and cognition indeed have implications for developing supply chain resilience. Furthermore, the mediators through which managers' social capital, human capital and cognition improve supply chain resilience are identified in the current study.Originality/valueThe study contributes to the extant literature on supply chain resilience, investigating the role that supply chain managers play in developing the resilience of their firm.
The influence of information configuration on mobile game download
Authors: Tang Zhongjun , He Bo 
Published: December 2021

PurposeThe study aims to show how several factors interact to promote mobile game download: the number of games released by a publisher, the quality of the games released, the popularity of a game's genre, the quality of borrowed intellectual property, the frequency of recommendations, intragenre ranking, consumer rating and review quantity.Design/methodology/approachSignaling theory was used to classify the mobile game information displayed on the Apple App Store into four groups. A conceptual model was proposed to illustrate the complex relationship between the information and download. Based on information on 203 mobile games in the seven days following their release, the model was empirically tested to identify the influence of information configuration on game download by combining fuzzy qualitative comparative analysis (fsQCA) and a fuzzy cognitive map (FCM).FindingsThree solutions were identified for high game download and two for low/medium. The number of previous games released by a publisher, intragenre ranking, consumer rating and review quantity are core conditions that reinforce high game download. The effects of one information type on another and on downloads change as coexisting information types change.Originality/valueThis study enriches existing knowledge about how combinations of multiple types of game information lead to game download and extends previous variance-based research. Combining an FCM with fsQCA can facilitate one’s understanding of the complex causal relationships between game information and download.
Information culture and recordkeeping: a case of Chinese enterprises
Authors: Lian Zhiying , Wang Ning , Oliver Gillian 
Published: December 2021

PurposeThe purpose of this paper is to report findings from an investigation on the information culture and recordkeeping in two Chinese companies, exploring the interaction between information culture and recordkeeping.Design/methodology/approachOn the basis of systematic literature review, this research investigates the information culture and recordkeeping in two Chinese companies by conducting in-depth interviews with the staff of the two companies.FindingsThe attitude of the leadership and the staff towards records and information is different in the result-oriented information culture and rule-following culture. If a company aims to stay innovative and competitive, an information culture that can facilitate the good governance of records and information should be developed, and information professionals can play a key role in working towards this.Originality/valueAs a qualitative study of information culture and recordkeeping in Chinese companies, this paper provides the insight into the interaction between information culture and recordkeeping, demonstrates the impact of information culture on information governance and identifies the factors influencing information culture in an organization.
Developing a resilient, robust and efficient supply network in Africa
Authors: Preston Jade F. , Cox Bruce A. , Rebeiz Paul P. , Breitbach Timothy W. 
Published: December 2021

PurposeSupply chains need to balance competing objectives; in addition to efficiency, supply chains need to be resilient to adversarial and environmental interference and robust to uncertainties in long-term demand. Significant research has been conducted designing efficient supply chains and recent research has focused on resilient supply chain design. However, the integration of resilient and robust supply chain design is less well studied. The purpose of the paper is to include resilience and robustness into supply chain design.Design/methodology/approachThe paper develops a method to include resilience and robustness into supply chain design. Using the region of West Africa, which is plagued with persisting logistical issues, the authors develop a regional risk assessment framework and then apply categorical risk to the countries of West Africa using publicly available data. A scenario reduction technique is used to focus on the highest risk scenarios for the model to be tractable. Next, the authors develop a mathematical model leveraging this framework to design a resilient supply network that minimizes cost while ensuring the network functions following a disruption. Finally, the authors examine the network's robustness to demand uncertainty via several plausible emergency scenarios.FindingsThe authors provide optimal sets of transshipment hubs with varying counts from 5 through 15 hubs. The authors determine there is no feasible solution that uses only five transshipment hubs. The authors' findings reinforce those seven transshipment hubs – the solution currently employed in West Africa – is the cheapest architecture to achieve resilience and robustness. Additionally, for each set of feasibility transshipment hubs, the authors provide connections between hubs and demand spokes.Originality/valueWhile, at the time of this research, three other manuscripts incorporated both resilience and robustness of the authors' research unique solved the problem as a network flow instead of as a set covering problem. Additionally, the authors establish a novel risk framework to guide the required amount of redundancy, and finally the out research proposes a scenario reduction heuristic to allow tractable exploration of 512 possible demand scenarios.
