We present the results of a missing-energy search for light dark matter which has a new interaction with ordinary matter transmitted by a vector boson, called dark photon A′. For the first time, this search is performed with a positron beam by using the significantly enhanced production of A′ in the resonant annihilation of positrons with atomic electrons of the target nuclei, followed by the invisible decay of A′ into dark matter. No events were found in the signal region with (10.1±0.1)×109 positrons on target with 100 GeV energy. This allowed us to set new exclusion limits that, relative to the collected statistics, prove the power of this experimental technique. This measurement is a crucial first step toward a future exploration program with positron beams, whose estimated sensitivity is here presented.

Maps as instructional resources and scholarly performance of junior secondary school students in social studies
Authors: Atubi Favour Onamrewho 
Published: February 2024

PurposeThe purpose of the research was to, first, investigate if the use of maps as instructional resources will boost scholarly performance and, second, examine if gender can moderate the effect of map usage on scholarly performance.Design/methodology/approachThe study was a quasi-experimental pre-test and post-test. A sample of 260 JSS II Students from 8 schools were selected through the purposive sampling technique. A Social Studies Scholarly Performance Test (SSSPT) with a reliability index of 0.79 was the instrument for data collection. The students were assigned into two groups: control and experimental. Both groups were pre-tested taught for a timeline of six weeks and thereafter post-tested.FindingsThe study reported a significant increase in the scholarly performance of students taught with maps; a significant difference occurred in the scholarly performance of both groups and gender did not moderate the effect of maps.Research limitations/implicationsThe social studies teachers used for the study did not have previous knowledge or map skills; this could have affected the outcome. Secondly, the treatment took place for just six weeks, and the time allotted for social studies in the school timetable was used. This may not have given the students enough time to master map interpretation.Practical implicationsA major implication of the study is that results will show that maps can promote the scholarly performance of students in social studies. Secondly, the fact that gender did not moderate the effect of maps suggests that maps are gender-friendly.Social implicationsThe results of the study, if implemented, would make social studies teachers to become inventive and resourceful in the use of maps as instructional resources for junior secondary students' scholarly performance in social studies without taking gender into consideration.Originality/valueThis study is a product of the researcher’s doctoral thesis; therefore, it is original and has value. The results are the product of a painstaking study carried out by the author for a period of three years on the effect of instructional resources on social studies students’ scholarly performance. Maps were one of the instructional resources studied for the award of a Ph.D. degree.

Published: February 2024

Purpose In this paper, improvements in reducing transmitted accelerations in a full vehicle are obtained by optimizing the gain parameters of an active control in a roughness road profile.Design/methodology/approach For a classically designed linear quadratic regulator (LQR) control, the vibration attenuation performance will depend on weighting matrices Q and R. A methodology is proposed in this work to determine the optimal elements of these matrices by using a genetic algorithm method to get enhanced controller performance. The active control is implemented in an eight degrees of freedom (8-DOF) vehicle suspension model, subjected to a standard ISO road profile. The control performance is compared against a controlled system with few Q and R parameters, an active system without optimized gain matrices, and an optimized passive system.Findings The control with 12 optimized parameters for Q and R provided the best vibration attenuation, reducing significantly the Root Mean Square (RMS) accelerations at the driver’s seat and car body.Research limitations/implications The research has positive implications in a wide class of active control systems, especially those based on a LQR, which was verified by the multibody dynamic systems tested in the paper.Practical implications Better active control gains can be devised to improve performance in vibration attenuation.Originality/value The main contribution proposed in this work is the improvement of the Q and R parameters simultaneously, in a full 8-DOF vehicle model, which minimizes the driver’s seat acceleration and, at the same time, guarantees vehicle safety.
From “dull” to “cheerful”: the relevance of Adam Smith for today
Authors: Paganelli Maria Pia 
Published: February 2024

PurposeIs there a secret recipe for economic growth?Design/methodology/approachNo, there is no recipe, but we can extrapolate some pieces of advice from Adam Smith.FindingsAn economy can leave behind its “dull” stagnant state and grow when its markets expand, when the productivity of its workers increases thanks to high compensations, which are seen as incentives to work harder and when lobbying and cronyism are kept at bay. Luck plays a role too, but these three ingredients are necessary, even if not sufficient, for an economy to grow and thus be “cheerful.”Originality/valueThese three aspects – expansion of market, liberal compensation of workers and lobbying – especially combined, have often been underestimated in Smith’s understanding of the possible sources of economic growth.
Exploring how retail and logistics service provider managers make sense of sustainability in last mile delivery
Authors: Heikkinen Helleke 
Published: February 2024

PurposeAn increasing number of last mile deliveries (LMDs) pose many sustainability challenges that retailers and logistics service providers (LSPs) can address. Using cognitive frames (CFs) as a lens, this study explored how retail and LSP managers make sense of sustainable LMDs.Design/methodology/approachThe methodological approach used is a multiple embedded case study. The data were obtained from interviews with retailers and LSPs, supplemented with secondary data for triangulation.FindingsThe findings present the operational aspects of LMDs that managers associate with sustainability and indicate that retail and LSP managers frame sustainability primarily as emission reduction. Managers indicate an externalization of responsibility and a compartmentalization of the supply chain, in which social sustainability is not associated with the last mile. Most managers indicate hierarchical CFs regarding sustainability, in which sustainability is an important topic but is subordinate to economic interests.Practical implicationsCollaboration between retailers, LSPs and other stakeholders is viewed as challenging but could alleviate some of the sustainability shortcomings and aid in the paradoxical framing and inclusion of social issues.Originality/valueA conceptualization of managerial CFs for sustainable LMDs, together with empirical frame indicators and three propositions, is presented, providing novel insights into how paradoxical CFs could make LMDs more sustainable. This approach illuminates the possibilities for how to untangle the operational manifestations of managerial framing and adds to the empirical exploration of CFs in supply chain management.
Visual attention and product interaction: a neuroscientific study on purchase across two product categories in a virtual store
Authors: Bigne Enrique , Simonetti Aline , Guixeres Jaime , Alcaniz Mariano 
Published: February 2024

PurposeThis research analyses the searching, interacting and purchasing behavior of shoppers seeking semidurable and fast-moving consumer goods in an immersive virtual reality (VR) store, showing how physical examinations and visual inspections relate to purchases.Design/methodology/approachAround 60 participants completed two forced-purchase tasks using a head-mounted display with visual and motor-tracking systems. A second study using a pictorial display of the products complemented the VR study.FindingsThe findings indicate differences in shopping behavior for the two product categories, with semidurable goods requiring greater inspection and deliberation than fast-moving consumer goods. In addition, visual inspection of the shelf and products was greater than a physical examination through virtual handling for both product categories. The paper also presents relationships between visual inspections and product interactions during the searching stage of purchase decisions.Originality/valueThe research consists of two types of implicit measures in this study: eye-tracking and hand-product interactions. This study reveals the suitability of implicit measures for evaluating consumer behavior in VR stores.
TLN-LSTM: an automatic modulation recognition classifier based on a two-layer nested structure of LSTM network for extremely long signal sequences
Authors: Qian Feng , Tu Yongsheng , Hou Chenyu , Cao Bin 
Published: February 2024

Purpose
Automatic modulation recognition (AMR) is a challenging problem in intelligent communication systems and has wide application prospects. At present, although many AMR methods based on deep learning have been proposed, the methods proposed by these works cannot be directly applied to the actual wireless communication scenario, because there are usually two kinds of dilemmas when recognizing the real modulated signal, namely, long sequence and noise. This paper aims to effectively process in-phase quadrature (IQ) sequences of very long signals interfered by noise.

Design/methodology/approach
This paper proposes a general model for a modulation classifier based on a two-layer nested structure of long short-term memory (LSTM) networks, called a two-layer nested structure (TLN)-LSTM, which exploits the time sensitivity of LSTM and the ability of the nested network structure to extract more features, and can achieve effective processing of ultra-long signal IQ sequences collected from real wireless communication scenarios that are interfered by noise.

Findings
Experimental results show that our proposed model has higher recognition accuracy for five types of modulation signals, including amplitude modulation, frequency modulation, gaussian minimum shift keying, quadrature phase shift keying and differential quadrature phase shift keying, collected from real wireless communication scenarios. The overall classification accuracy of the proposed model for these signals can reach 73.11%, compared with 40.84% for the baseline model. Moreover, this model can also achieve high classification performance for analog signals with the same modulation method in the public data set HKDD_AMC36.

Originality/value
At present, although many AMR methods based on deep learning have been proposed, these works are based on the model’s classification results of various modulated signals in the AMR public data set to evaluate the signal recognition performance of the proposed method rather than collecting real modulated signals for identification in actual wireless communication scenarios. The methods proposed in these works cannot be directly applied to actual wireless communication scenarios. Therefore, this paper proposes a new AMR method, dedicated to the effective processing of the collected ultra-long signal IQ sequences that are interfered by noise.
Does multiple borrowing and COVID-19 pandemic matter in a microfinance contract?
Authors: Iqbal Zahid , Rao Zia-ur-Rehman , Ahmad Hassan 
Published: February 2024

Purpose
To improve the loan repayment performance (LRP) of microfinance banks (MFBs) in Pakistan, this study aims to look at the direct impact of multiple borrowing (MB) on LRP and client-business performance (CBP), as well as the direct impact of CBP on LRP. The moderating function of pandemic factors in the relationship between MB and CBP, as well as the mediating effect of CBP in the association between MB and LRP, was also investigated in this study.

Design/methodology/approach
A questionnaire was used to obtain data from 531 lower-level workers of microfinance institutions (MFIs) for the study. The respondents were chosen using stratified sampling, which divided the target population into four influential groups: lending officers in agriculture, lending officers in businesses, lending officers in gold loans and lending officers in salary loans. In this study, a two-stage structural equation modeling approach was used, including a measurement model (outer model) and a structural model (inner model). The validity and reliability of the questionnaire were investigated using the measurement model (outer model), whereas PLS-SEM bootstrapping was performed to test the hypothesis and find the relationship among different underpinning constructs by using the structural model (inner model).

Findings
The outcomes of this study demonstrate that MB has a direct impact on CBP, and that CBP has a direct impact on LRP. MB, on the contrary, had no direct and significant impact on LRP in this study. The idea that CBP mediates the relationship between MB and LRP, as well as the moderating effect of pandemic factors on the relationship between MB and CBP, is supported by this research.

Originality/value
Until now, the influence of MB on LRP via the mediating role of CBP and the moderating role of a pandemic factor in the setting of Pakistani MFBs has received little attention. During the COVID-19 pandemic, this research also aids MFBs in better understanding MB and its impact on LRP. Furthermore, based on the findings of this study, Pakistani MFIs can enhance their LRP by implementing new lending regulations, particularly with reference to MB and the COVID-19 pandemic.
Reforming resistant KIPOs to achieve justice: can the judiciary system hybridise?
Authors: Monfardini Patrizio , Macchia Silvia , Eltrudis Davide 
Published: February 2024

PurposeKnowledge-intensive public organizations (KIPOs henceforth) rely heavily on knowledge as the primary resource to provide public services. This study deals with a specific kind of KIPO in the judiciary system: the courts. The paper aims to explore the court’s managerial and organisational change resulting from the national recovery and resilience plan (NRRP) reform in response to Covid-19, focussing on how this neglected KIPO responds to change, either by showing acts of resistance or undergoing a hybridisation process.Design/methodology/approachThe paper adopts a qualitative research design, developing an explorative case study to investigate the process of a court’s managerial and organisational change caused by NRRP reform and to shed light on how this neglected KIPO reacts to change, showing resistance acts and developing the hybridisation process. Thirty-one interviews in six months have been conducted with the three main actors in Courts: judges, clerks and trial clerks.FindingsThe paper shows that in this understudied KIPO, judges fiercely resist the managerial logic that decades of reforms have been trying to impose. The recent introduction of an office for speeding up trials (Ufficio Per il Processo (UPP)) was initially opposed. Then, the resistance strategy changed, and judges started to benefit from UPP delegating repetitive and low-value tasks while retaining their core activities. Clerks approached the reform with a more positive attitude, seeing in UPP the mechanism to bridge the distance between them and the judges.Originality/valueConsidering their relevance to society, courts must be more addressed in KIPOs' studies. This paper allows the reader to enter such KIPO and understand its peculiar features. Secondly, the article helps to understand micropractices of resistance that may hinder the effectiveness of managerial reforms.

Authors: Peršolja Melita , Žvanut Boštjan , Rot Špela , Markič Mirko 
Published: February 2024

Purpose
This study aims to endeavor to discern the predominant leadership styles used by nursing managers within the framework of Slovenian primary health centers. Using a quantitative research approach, the study was conducted through the administration of a structured questionnaire.

Design/methodology/approach
The investigation encompassed 67 nursing managers, representing the entire spectrum of primary health centers in Slovenia. A stratified representative subset comprising 53 top nursing managers actively participated in this study.

Findings
The prevailing leadership style among nursing managers predominantly manifests as the “integrated” style, characterized by a balanced emphasis on both interpersonal relationships and task-oriented elements. These nursing leaders exhibited a proclivity for fostering collaborative teamwork, with their leadership approach notably shaped by traits such as positive thinking, self-assuredness, comprehensive leadership knowledge and an intrinsic motivation to guide and inspire individuals. Notably, leadership knowledge emerged as the most influential factor in determining the selected leadership style. The study’s findings recognize specific areas in which leadership competencies among nurse managers may require further enhancement and development.

Originality/value
The study’s findings are based on a specific subset of nursing leaders in a particular region, which can add to the originality, especially as there is limited prior research in this specific context. The study’s exploration of leadership styles is original in the sense that it provides insights into the leadership behaviors and traits of nursing managers in the given context. The emphasis on factors such as positive thinking and leadership knowledge as influential elements adds originality to the study.
‘Even a piece of paper has two sides’: multi‐scalar cosmologies of Japanese New Year cards
Authors: Daniels Inge 
Published: February 2024

AbstractAnnually on 1 January, Japan's efficient postal system circulates 2.5 billion New Year cards to arrive simultaneously in every home in the country. Based on ethnographic fieldwork around Osaka, this article investigates the continued popularity of this exchange of paper forms in an age of smartphones and fast internet connections. Extending recent anthropological scholarship about digital data, I argue that these seemingly trivial cards have transformative potential. They are active, potent participants in the cultivation, accumulation, and ongoing care of multiple networks of social, economic, and spiritual relationships. Through an analysis of the material and aesthetic qualities of the cards, I highlight how their front‐back design embodies co‐existing, but contrasting, dimensions of Japanese relations along a qualification‐quantification and personalization‐standardization axis. The cards also produce depth and scale by linking intimate, domestic concerns with larger political and economic interests, while weaving together multiple temporal dimensions. Ultimately, they exemplify how the manipulation of surfaces can have profound cosmological consequences. These cards possess a spiritual and social potency that generates an all‐encompassing, intimate closeness that yearly rejuvenates society by reconstituting individuals as part of the whole.
The symbiont Wolbachia alleviates pesticide susceptibility in the two‐spotted spider mite Tetranychus urticae through enhanced host detoxification pathways

Published: February 2024

AbstractThe two‐spotted spider mite (Tetranychus urticae) is one of the most well‐known pesticide‐resistant agricultural pests, with resistance often attributed to changes such as target‐site mutations and detoxification activation. Recent studies show that pesticide resistance can also be influenced by symbionts, but their involvement in this process in spider mites remains uncertain. Here, we found that infection with Wolbachia, a well‐known bacterial reproductive manipulator, significantly increased mite survival after exposure to the insecticides abamectin, cyflumetofen, and pyridaben. Wolbachia‐infected (WI) mites showed higher expression of detoxification genes such as P450, glutathione‐S‐transferase (GST), ABC transporters, and carboxyl/cholinesterases. RNA interference experiments confirmed the role of the two above‐mentioned detoxification genes, TuCYP392D2 and TuGSTd05, in pesticide resistance. Increased GST activities were also observed in abamectin‐treated WI mites. In addition, when wild populations were treated with abamectin, WI mites generally showed better survival than uninfected mites. However, genetically homogeneous mites with different Wolbachia strains showed similar survival. Finally, abamectin treatment increased Wolbachia abundance without altering the mite's bacterial community. This finding highlights the role of Wolbachia in orchestrating pesticide resistance by modulating host detoxification. By unraveling the intricate interplay between symbionts and pesticide resistance, our study lays the groundwork for pioneering strategies to combat agricultural pests.
