Price‐knowledge‐induced bias: a cross‐cultural comparison
Authors: Gallimore Paul , Wolverton Marvin
Published: July 2002

Explains that bias in human problem‐solving behaviour may sometimes conflict with the assumptions that underlie normative models of valuation. Possibilities include faulty perceptions of the task, routinized valuation procedures that rely heavily on pending sale price‐knowledge and reliance on innate and distorting problem‐solving heuristics. Describes an experiment conducted with appraisers in the USA and valuers in the UK to investigate the impact of price knowledge on the process of valuation and the search and selection of comparable sales. Concludes that both appraisers and valuers can be subject to price‐knowledge bias, reflected in the choice of the less than “best” comparables and in the actual value estimate. Discusses how cultural differences in the appraisal and valuation processes, especially in the transparency of comparables adjustments, help to explain these effects.
Expert property negotiators and pricing information, revisited
Authors: Black Roy T.
Published: July 2002

Builds on a previous study and examines the influence of asking prices as anchors in the real property negotiating process. Previous studies have shown that the human mind uses short cuts (heuristics) in process information. Describes a study which gives further evidence that negotiators familiar with real property will, in many cases, devalue cognitively difficult pricing information and base their negotiation expectations on the seller’s asking price. Concludes that the seller’s asking price is thus a potential source of bias.
An adaptive notch filtering approach with frequency holder for attitude control of flexible launch vehicles
Authors: He Xiao , Yang Jinzhao , Liu Yuxi , Hu Cunming , Tan Shujun
Published: February 2025

Purpose

This study aims to investigate an adaptive notch filtering approach to suppress the effects of elastic vibration on the attitude control of flexible launch vehicles.

Design/methodology/approach

First, the dynamics model of the flexible launch vehicle and baseline PID controller are presented. Furthermore, the frequency identification algorithm based on a second-order notch filter is developed to identify the elastic vibration frequency. Finally, a frequency holder is developed to update the notch frequency of the adaptive notch filter.

Findings

The proposed adaptive notch filter with a frequency holder can identify the vibration frequency accurately, update the notch frequency appropriately and suppress the effects of the elastic vibration on the attitude control of flexible launch vehicles effectively.

Originality/value

A novel adaptive notch filter with a frequency holder is proposed to address the adaptive filtering problem of elastic vibrations under nonelastic interference and elastic frequency uncertainty. Compared with the conventional filter for attitude control of flexible launch vehicles, an adaptive filter with a proposed frequency holder is developed to solve the problem of the frequency real-time update during the vibration suppression and frequency keeping after the vibration suppression.
The physical geometries of sacred spaces: methodological challenges in applying practice-based approaches to study sacred shrines
Authors: Flint Ashery Shlomit , Stadler Nurit
Published: February 2025

Purpose

While the praxeological turn in social research has resulted in many empirical studies, there are few works utilizing this concept as a framework to analyze complex architectural–anthropological phenomena, in particular in sacred geographies. This study addresses this gap by integrating architectural and anthropological approaches to explore interactions between humans, non-humans and what are considered sacred environments.

Design/methodology/approach

It presents case studies of the womb–tomb archetypes of Rabbi Zechariah and Rabbi Avdimi in northern Israel to demonstrate how ritualistic practices shape and are shaped by these structures that are deeply connected to human anatomy, lifecycles and territoriality.

Findings

Our analysis uses isovist analysis to examine the spatial dynamics of sacred architectures, which is then applied to Navisworks Roamer 3D Viewer to estimate the materials from a sacred architectural–anthropological perspective that better reflects body movements and ritualistic performances.

Research limitations/implications

Based on our findings from interviews, observations and architectural measures, we reveal how these practices simultaneously articulate land as property—an exclusive, territorial claim rooted in religious and political narratives—and as connectivity, emphasizing relational ties that foster a sense of belonging and interdependence with the land.

Practical implications

This duality is represented by the embodied gestures of bending, crawling and touching in these spaces, which establish both symbolic ownership and deep relationships with the environment.

Social implications

The findings emphasize the importance of bodily engagements and narrative constructions in reimagining human–environment relationships and contribute to the broader discourse on practice-based boundary making approaches in architectural studies.

Originality/value

They also demonstrate how body-environment practices shape ongoing negotiations of land, belonging and totemic relationships within complex cultural landscapes.

Authors: Chen Jieh-Haur , Su Mu-Chun , Lin Wei-Jen , Yu Tzuyang , Wu Kai-Yuan
Published: February 2025

Purpose

The research objective is to establish a smart system for building operation and maintenance using self-organizing map-based cluster merging (SOMCM) algorithm.

Design/methodology/approach

The process begins with a thorough literature review to establish the interface framework, followed by its design. An empirical study in Taoyuan City’s industrial park, involving 46 buildings and 3,526 maintenance records, informed development. By integrating the “Shared Facility Management System Equipment Repair Module” and the “Maintenance Management System for Existing Facilities,” 21 enhanced interface components were created. All work orders are stored in a database for aggregation, statistical analysis and clustering using the algorithm SOMCM, aiding repair decision-making.

Findings

The outcomes stemming from the proposed methodology culminate in the identification of seven patterns that can significantly enhance the efficiency of maintenance operations: (1) simplify current self-repair to outsourcing; (2) modify the current traditional contract type to open contract type; (3) adopt massive procurement for major facilities (e.g. air conditioning); (4) schedule power supply systems in a systematic and efficient way; (5) establish maintenance patterns as suggested to eliminate warehouse for spares; (6) reallocate maintenance resources in a seasonal cycle; (7) set up a standby team to resolve emergency repairs. The findings can reduce a significant amount of time and cost for the investigated industrial park.

Originality/value

Maintenance work has faced delays, aging equipment has caused component damage, and park structures no longer meet operational needs. Addressing these challenges, the study introduces a novel SOMCM approach for smart building operation and maintenance. This approach emphasizes creating a user-friendly, practical system pivotal to platform success. By integrating demand-driven strategies, it enhances traditional maintenance processes and offers innovative solutions to operational and management issues, ensuring alignment with modern requirements and improved efficiency.
Driving pre-match fan engagement through social media: effects of message characteristics and team performance
Authors: Kaushik Kapil , Pathak Atul Arun , Mishra Abhishek
Published: February 2025

Purpose

This study aims to understand the kind of content and context that effectively create higher fan social media engagement (SME) through pre-match content posted by sports teams.

Design/methodology/approach

This research examines the effect of inspirational, informational, entertaining and warmth content appeal on affective and cognitive responses from fans in the form of likes and shares. Messages on X (previously Twitter), chosen as a representative social media platform, from the teams participating in the Indian Premier League, were analysed using regression models to validate the proposed model empirically.

How to make sponsorship activations memorable: the power of meaningfulness
Authors: Marceau Pascale
Published: February 2025

Purpose

Building on memory-dominant logic, this study proposes a theoretical model explaining the antecedents and consequences of memorable activation experience.

Design/methodology/approach

Through a qualitative research methodology – a narrative review, an analysis of current activation trends, eight interviews and content validity evaluation by five experts – this study hypothesized that six antecedents (positive emotions, novelty, meaningfulness, involvement, experience intensification and serendipity) positively influence memorable activation experience, which in turn significantly affects two managerial outcomes: positive word-of-mouth and sponsor recall. To evaluate the proposed hypotheses, this study analyzed data collected from consumers who participated in a sponsorship activation by Lafleur (n = 215) and Salon de jeux de Québec (n = 306) using partial least squares structural equation modeling (PLS-SEM).

Findings

The results indicate that all antecedents, except for novelty, have a significant impact on memorable activation experience, which positively impacts positive word-of-mouth and sponsor recall.

Originality/value

By extending the scope of memorable experience to the sponsorship field, this study enhances its conceptualization and application. It also contributes to a better understanding of designing activations to increase the likelihood of memorability, thus improving their effectiveness.
People first, preservation later: critical community engagement to activate dialogue-based archives
Authors: Han Yingying
Published: February 2025

Purpose

This study explores whether and how archival records can address the social oppression faced by Chinese immigrants through community engagement, with the aim of fostering transformative change within marginalized communities.

Design/methodology/approach

Guided by Paulo Freire’s concepts of generative themes and dialogue, this community-based qualitative case study engaged seven participants in a workshop that used archival materials about Chinese immigration history. Participants interacted with three groups of materials and had collective discussions. They reflected on their perceptions of the history and stories documented in the archival materials and further shared insights on the fairness of current immigration systems, as well as potential changes necessary for a more equitable immigration system.

Findings

The archival records activated dialogues in which participants expressed disappointment with historical and ongoing exclusion by the government. They critiqued social beliefs such as the expectation that Asians must conform to white normativity to be accepted in the United States. Participants explored the challenges facing the community, reflected on how their experiences resonate with the archival stories and identified the “cyclical oppression” of the Chinese immigrant community. I propose this process as “dialogue-based archives,” which engages marginalized community members in conversations through archival records, fostering mutual respect, active listening, sharing of lived experiences and critical reflection on oppression.

Originality/value

Dialogue-based archives effectively engage marginalized communities. It also constitutes rigorous scholarship, contributing to the field of Library and Information Science (LIS) by challenging the dominant white-elitist and Euro-Anglo-centric discourse within the field and highlighting the value of archival engagement work in addressing the needs of marginalized communities. It also specifically contributes to critical archival studies by providing grassroots insights into collection building and description.
Prioritization and relational analysis of green supplier evaluation criteria in the textile industry
Authors: Yıldırım Söylemez Esra , Kayabaşı Aydın , Demirağ Fatma
Published: February 2025

Purpose

This study aims to determine the extent to which the textile industry considers ecological issues in the supplier evaluation process by examining the relationships between environmental and operational criteria.

Design/methodology/approach

The supplier evaluation process within the industry was examined using the Fuzzy DEMATEL-based Analytic Network Process (FDANP) hybrid method. Criterion relationships were determined using the Fuzzy DEMATEL method. Two different ANP processes (the classical DANP approach and the new DANP approach) were used to assess the criterion weights, and the analysis results were compared. The satisfaction levels of suppliers with whom businesses collaborated were also examined using IPA analysis.

Findings

The results of the hybrid approaches with different steps in the study also differ. While the classic FDANP approach prioritizes cost and quality in the green supplier evaluation process, green products and EMS come to the fore according to the new FDANP approach. In addition, while businesses are satisfied with the operational performance of suppliers, their environmental performance remains below average.

Research limitations/implications

This study was conducted in a sector-specific context, limited to Denizli province and green raw material suppliers.

Practical implications

This study revealed important findings regarding environmental awareness in buyer-supplier relations in the textile industry and offers a practical decision-making tool for decision- makers.

Social implications

The results of this study may help industrial enterprises gain an environmental perspective when planning their operations to create a more sustainable environment.

Originality/value

This study contributes to the literature from a holistic perspective by examining the role and importance of operational and environmental criteria in the green supplier evaluation process in the textile industry.

Published: February 2025

Purpose

The study investigates the serial mediation of green work engagement and green individual and collective psychological ownership in the nexus between green inclusive leadership and green creativity among hotel employees in Ghana.

Design/methodology/approach

Four-hundred and eighty-four (484) samples were selected using convenience sampling technique from 3–4 star rated hotels. The data solicited with a self-reported questionnaire was analyzed using SEM-PLS.

Findings

The findings reveal that green inclusive leadership directly improves hotel employee’s green creativity, green work engagement and green individual and collective psychological ownership. Green work engagement and green individual and collective psychological ownership separately and serially mediate the relationship between green inclusive leadership directly improves hotel employee’s green creativity.

Research limitations/implications

The findings imply that hotel managers should adopt green inclusive leadership practices to directly foster employees' green creativity, engagement and ownership of environmental initiatives. Additionally, cultivating green work engagement and psychological ownership can further amplify the positive impact of leadership on green creativity through both separate and serial mediation effects.

Originality/value

One of the first studies to have examined green work engagement and individual and collective psychological ownership as a serial mediation between green inclusive leadership and green creativity among hotel employees.
Adoption of blockchain technology in promoting halal compliance
Authors: Purusottama Ambara , Simatupang Togar M.
Published: February 2025

Purpose

Blockchain technology (BT)-based halal discussions have gained momentum as their significant benefits have become evident. However, explaining the halal compliance of blockchain-based products remains insufficient. This study attempts to confront this deficiency and promote a thorough understanding of halal compliance using BT.

Design/methodology/approach

The research design emphasized the relationship between theoretical and empirical evidence in adopting BT to produce novel knowledge for halal compliance. Furthermore, this study formulated a model resulting from an iterative process between theoretical and empirical evidence, as confirmed by multiple case studies. To produce solid findings, the data were collected using a few approaches involving key actors in halal-specific areas in Indonesia, such as in-depth interviews, direct observations and documentation.

Findings

The study shows that the developed model elucidates the synthesis of BT and halal compliance. BT’s features can facilitate the dimensions of halal compliance and can be applied in multiple cases. The BT features work complementarily, and it was found that some features work dominantly in each dimension for halal compliance, while other features accentuate a minor role. Other findings identified discrepancies among the cases since they had different characteristics.

Originality/value

This study initiates an integrative model combining BT features and halal compliance dimensions, including traceability, integrity and authenticity. The model, along with the study’s implications and contributions, is then explained in detail in this article.

Research on intra-layer partition adaptive slicing algorithm for fused deposition modeling
Authors: Shen Sijia , He Ketai , Yu Biqiang , Zhai Chenlong , Ji Tianyan
Published: February 2025

Purpose

This paper proposes a new intra-layer partition adaptive slicing algorithm for FDM 3D printing, aiming to further improve forming efficiency based on the adaptive slicing algorithm while preserving the surface finish quality of the formed model.

Design/methodology/approach

This method initially applies a large layer thickness for primary slicing, then refines layer thickness in layer height ranges with significant cross-sectional contour changes. Refined layers are partitioned: the internal region uses the large layer thickness for efficiency, while the external region uses a smaller layer thickness for surface quality. A thickness ratio and transition zone between regions prevent overlaps and gaps in printing paths.

Findings

The experimental results show that, compared to traditional adaptive slicing algorithms, the intra-layer partition adaptive slicing algorithm can effectively improve forming efficiency for most models while ensuring the model’s surface finish, with minimal impact on the bonding strength of the model.

Originality/value

The intra-layer partition adaptive slicing algorithm is a novel algorithm improved upon the traditional adaptive slicing algorithm, enabling models to achieve higher printing efficiency while maintaining the surface finish provided by the conventional adaptive slicing algorithm. This algorithm is of significant importance to vendors and individual users who provide printing services for large-sized fused deposition modeling models, as it can greatly enhance their production efficiency.
Interactions between the promotion of prosocial and pro-self values, and entrepreneurial social identities in shaping value creation aims and passion
Authors: Vörös Zsófia , Kehl Dániel
Published: February 2025

Purpose

Due to the different logic of economic or entrepreneurial, and social value creation, hybrid entrepreneurs (entrepreneurs whose organization is committed to create both entrepreneurial and social values) often make compromises at the expense of economic rationality or social value creation. The purpose of this paper is to examine how entrepreneurial social identities interact with the promotion of pro-self and prosocial values to influence hybrid entrepreneurs’ choice of predominant values to create and their entrepreneurial passion.

Design/methodology/approach

To answer the research questions, we designed an experiment using an established priming protocol to temporarily increase the saliency of prosocial and pro-self cultural values. In the experiment, students (n = 203) with no entrepreneurial experience chose a hybrid venture to join its founding team in three conditions: neutral (control group, n = 72), social priming (n = 65) and commercial priming (n = 66).

Findings

The results indicate that behavioral choices on the type of the predominant value to create are linked to entrepreneurial social identities. The temporary increase in the saliency of prosocial or pro-self cultural values does not affect the predominant value to create through hybrid entrepreneurial venturing, but influences how passionately entrepreneurs act.

Research limitations/implications

The results are based on the behavior of university students who did not risk losing income because of their behavioral choice and could not opt out of entrepreneurship. Even if university students resemble the population of interest, field studies could contribute to the examination of the research questions of this explorative study and corroborate the results. Future studies should examine if, when and how the promotion of prosocial and pro-self cultural values may change entrepreneurs’ social identities and primary value creation aims.

Originality/value

The entrepreneurship literature rarely takes into consideration that the effects of cultural values might fluctuate along entrepreneurs’ personality traits and identities. This paper examines how entrepreneurial social identities and the temporary promotion of prosocial, and pro-self values interact to influence value creation choices during hybrid entrepreneurial venturing.
Localization of aquaporin‐5 in sweat glands and functional analysis using knockout mice
Authors: Song Yuanlin , Sonawane Nitin , Verkman A. S.
Published: July 2002

Sweat secretion involves the transport of salt and water into the lumen of the secretory coil of the sweat gland. By analogy to salivary and submucosal glands, where fluid secretion is aquaporin‐5 (AQP5) dependent, we postulated that aquaporin water channels might facilitate sweat secretion. Immunolocalization with specific antibodies revealed strong expression of AQP5 at the luminal membrane of secretory epithelial cells in sweat glands in mouse paw skin. Novel quantitative methods were developed to compare sweat secretion in wild‐type mice and mice lacking AQP5. Total hindpaw sweat secretion was measured by proton nuclear magnetic resonance of sweat‐derived 1H2O in 2H2O solvent, and sweat secretion from individual glands was measured by real‐time video imaging of sweat droplet formation under oil. Sweat secretion rates after pilocarpine stimulation did not differ in wild‐type mice (0.21 ± 0.03 nl min−1 gland−1) vs. mice lacking AQP5 (0.19 ± 0.04 nl min−1 gland−1). The lack of effect of AQP5 on sweat secretion rate was confirmed by microcapillary collections of sweat from defined regions of mouse paws. Also, as by direct counting of droplets, the number of functional sweat glands was not affected by AQP5 deletion. Sweat gland morphology was similar in wild‐type and AQP5 null mice. From sweat coil geometry and gland secretion rate, the rate of fluid secretion was estimated to be 130 nl min−1 cm−2 of secretory epithelium, substantially lower than that of > 500 nl min−1 cm−2 in kidney proximal tubules and salivary glands, where active fluid absorption or secretion is aquaporin dependent. These results indicate the expression of AQP5 in sweat gland secretory epithelium, but provide direct evidence against its physiological involvement in sweat fluid secretion in mice.
Functional characterisation and subcellular localisation of HCN1 channels in rabbit retinal rod photoreceptors
Authors: Demontis Gian Carlo , Moroni Anna , Gravante Biagio , Altomare Claudia , Longoni Biancamaria , Cervetto Luigi , DiFrancesco Dario
Published: July 2002

Gating of voltage‐dependent conductances in retinal photoreceptors is the first step of a process leading to the enhancement of the temporal performance of the visual system. The molecular components underlying voltage‐dependent gating in rods are presently poorly defined. In the present work we have investigated the isoform composition and the functional characteristics of hyperpolarisation‐activated cyclic nucleotide‐gated channels (HCN) in rabbit rods. Using immunocytochemistry we show the expression in the inner segment and cell body of the isoform 1 (HCN1). Electrophysiological investigations show that hyperpolarisation‐activated currents (Ih) can be measured only from the cell regions where HCN1 is expressed. Half‐activation voltage (–75.0 ± 0.3 mV) and kinetics (t1/2 of 101 ± 8 ms at –110 mV and 20 °C) of the Ih in rods are similar to those of the macroscopic current carried by homomeric rabbit HCN1 channels expressed in HEK 293 cells. The homomeric nature of HCN1 channels in rods is compatible with the observation that cAMP induces a small shift (2.3 ± 0.8 mV) in the half‐activation voltage of Ih. In addition, the observation that within the physiological range of membrane potentials, cAMP does not significantly affect the gain of the current‐to‐voltage conversion, may reflect the need to protect the first step in the processing of visual signals from changes in cAMP turnover.

Recombinant adenoviruses were used to overexpress green fluorescent protein (GFP)‐fused auxiliary Ca2+ channel β subunits (β1‐β4) in cultured adult rat heart cells, to explore new dimensions of β subunit functions in vivo. Distinct β‐GFP subunits distributed differentially between the surface sarcolemma, transverse elements, and nucleus in single heart cells. All β‐GFP subunits increased the native cardiac whole‐cell L‐type Ca2+ channel current density, but produced distinctive effects on channel inactivation kinetics. The degree of enhancement of whole‐cell current density was non‐uniform between β subunits, with a rank order of potency β2aαβ4 > β1b > β3. For each β subunit, the increase in L‐type current density was accompanied by a correlative increase in the maximal gating charge (Qmax) moved with depolarization. However, β subunits produced characteristic effects on single L‐type channel gating, resulting in divergent effects on channel open probability (Po). Quantitative analysis and modelling of single‐channel data provided a kinetic signature for each channel type. Spurred on by ambiguities regarding the molecular identity of the actual endogenous cardiac L‐type channel β subunit, we cloned a new rat β2 splice variant, β2b, from heart using 5′ rapid amplification of cDNA ends (RACE) PCR. By contrast with β2a, expression of β2b in heart cells yielded channels with a microscopic gating signature virtually identical to that of native unmodified channels. Our results provide novel insights into β subunit functions that are unattainable in traditional heterologous expression studies, and also provide new perspectives on the molecular identity of the β subunit component of cardiac L‐type Ca2+ channels. Overall, the work establishes a powerful experimental paradigm to explore novel functions of ion channel subunits in their native environments.
Rolling Element Bearing Defect Detection and Diagnostics Using Displacement Transducers

Published: July 2002

This paper introduces the methodology of rolling element bearing defect detection using high-gain displacement transducers. The nature of defect influence on the outer race deflection in the vicinity of the transducer tip in time base has been established. Inner race, outer race, and rolling element (ball/roller) defects, which often occur sequentially, can be clearly identified according to spike signals on the time-varying outer race deflection curve along with known bearing frequencies. The developed techniques are fully corroborated by experimental data. Spike-to-deflection amplitude ratio, which is almost independent of changes in speed and load for a given defect, is used to judge the defect severity. Spectral characteristics due to these defects have also been found. It is shown that this direct measurement by using displacement transducers without casing influence, which would be inevitable by using accelerometers mounted on the casing, is a reliable approach to detect bearing defects as well as their severity and locations.
On the Effect of Swirl Flow of Gas Turbine Exhaust Gas in an Inlet Duct of Heat Recovery Steam Generator
Authors: Lee B. E. , Kwon S. B. , Lee C. S.
Published: July 2002

Computational and experimental studies are performed to investigate the effect of swirl flow of gas turbine exhaust gas (GTEG) in an inlet duct of a heat recovery steam generator (HRSG). A supplemental-fired HRSG is chosen as the model studied because the uniformity of the GTEG at the inlet plane of the duct burner is essential in such applications. Both velocity and oxygen distributions are investigated at the inlet plane of the duct burner installed in the middle of the HRSG transition duct. Two important parameters, the swirl angle of GTEG and the momentum ratio of additional air to GTEG, are chosen for the investigation of mixing between the two streams. It has been found that a flow correction device (FCD) is essential to provide a uniform gas flow distribution at the inlet plane of the duct burner.

Water mites of the genus Teutonia Koenike, 1889 are often common in cold montane lakes and pools of shaded streams and include the fastest swimmers among the water mites. This study provides the first-time calibrated phylogeny of this genus in Europe. Fossil-calibrated modelling reveals that the most recent common ancestor of the European Teutonia spp. originated in the Oligocene. Phylogenetic analyses show the presence of at least five species-level lineages within European teutoniid mites, with the T. corsicana-clade as the earliest branching lineage. We infer the origin of Teutonia corsicana at 29.0 million years ago, near the Eocene–Oligocene boundary, indicating that this species or its most recent ancestor was already present on the Corsica-Sardinia block when it broke off from the Iberian Peninsula. The remaining Teutonia clades are relatively younger and began their divergence in the early Miocene (ca. 21 million years ago) and continued with individual species throughout the Miocene. Finally, as a result of an integrative taxonomic approach, three species, i.e., T. lusitanica sp. nov., T. herminiana sp. nov. and T. condei sp. nov. are described as new for science, and the presence of T. cometes is for the first time molecularly confirmed for Portugal.

Extending the coherence time of quantum systems to their physical limit is a long-standing pursuit and critical for developing quantum science and technology. By characterizing all the microscopic noise sources of the electronic spin [nitrogen-vacancy (NV) center] in diamonds using complete noise spectroscopy, we observe a previously unforeseen noise spectrum manifested as the empirical limit (

for NVs, from room temperature down to 220 kelvin. Our observations, including the independence across different spatial sites and its dependence on temperature in the same way as spin-lattice relaxation, suggest an emerging decoherence mechanism dominated by spin-lattice interaction. These results provide a unified and universal strategy for characterizing and controlling microscopic noises, thereby paving the way for achieving the physical limit in various solid-state systems.
