双选信道下的CPM-FMT联合调制

为了提高双选择性衰落信道下滤波多音（FMT）多载波系统的性能,从子载波调制角度出发,提出了一种连续相位调制-滤波多音（CPM-FMT）联合调制方法。该方法首先将比特数据流串并转换后进行CPM映射,接着对映射后的信号进行重组,然后进行FMT调制。在接收端首先将接收的信号进行FMT解调并进行逆重组,然后进行CPM解映射恢复出比特数据流。实验结果表明,CPM-FMT联合调制方法优于传统调制的QPSK-FMT方法,在误码率为10-3时,白噪声信道下性能最大提高了10 dB,时间频率双选择性衰落信道下性能提高了5 dB,同时该方法对多谱勒频偏具有良好的稳健性。这表明CPM-FMT方法能显著提高FMT系统在双选择性衰落信道下的性能,可应用于高速移动环境下的宽带无线传输系统。     

Gradual stimulation of respondents' reflexivity: A research design for studying unreflexive consumers

In interpretive research accounts, reflexivity has been understood primarily in terms of the researcher's reflexivity, while the respondent's reflexivity has been considered only marginally. We regard this gap as critical and therefore introduce a research design for the gradual stimulation of respondents' reflexivity (GSRR), which we propose as a methodological tool for strengthening research validity. First, to frame our argumentation in the contemporary socio-technological context, we emphasize the need to focus on the respondent's reflexivity in the onto-epistemological conditions of the hybrid space and posthuman consumer culture, which unprecedentedly eliminate actors' abilities to monitor their actions reflexively. Second, we present and methodologically examine the GSRR as a 3-phase sequential mixed-method research design for stimulating respondents' reflexivity. GSRR's logic is as follows: the questionnaire captures what respondents think they are doing; the digital self-tracking diary captures what they are doing and what they often do not acknowledge (unreflexivity); the interviews use the previous phases' data to elicit respondents' reflexivity. Third, we present examples from our research practice to demonstrate the strengthening of data validity elicited from respondents by stimulating their reflexivity. We conclude by outlining the GSRR's possible future applications and directions.     

Consumer cynicism: Interdisciplinary hybrid review and research agenda

Over the years, consumers have been questioning the intentions and actions of firms, resulting in a cynical attitude and behaviour. Due to the severity of the outcomes that cynical consumers may display, reputed journals and prolific researchers have addressed the core issue in their own unique ways. However, no single study offers a uniform, comprehensive, and contemporary review of consumer cynicism literature. Thus, we use an interdisciplinary approach to study the literature spanning 47 years (1976–2022) on cynicism in consumer research, psychology, and organizational domains through a hybrid review involving bibliometric and systematic literature reviews. Following the SPAR-4-SLR protocol, this review shows the most cited and co-cited articles, researchers, and keywords in cynicism research. We infer that the consumer cynicism construct draws heavily from the organizational behaviour area, possessing the potential to be correlated with, and extended to interdisciplinary research. Also, we offer an all-inclusive model of the predictors and predictands of consumer cynicism based on the ADO-TCM framework. We close this study with its academic contributions, practical implications, and future research directions using the ADO-TCM framework.     

When a clean scent soothes the soul: Developing a positive attitude toward sharing service space with strangers

In the context of sharing services, this research examines how ambient scent can improve the perception of the presence of other sharers. Four experiments conducted in real conditions (open-plan workspaces, car-sharing services, rail-stations, and library) show that the diffusion of a clean scent promotes positive attitudes toward sharing space with others. Three alternative explanations are assessed: 1) perceived cleanliness of the space; 2) other users' behaviors; and 3) user's mood. The results indicate that throughout the four experiments, the effect of scents is mediated only by the positive mood induced by the scent.     

Impact investing in biodiversity conservation with bonds: An analysis of financial and environmental risk

Impact investments have the dual goals of generating profit and environmental and/or social impact from the same project or enterprise. This article examines recent impact investments in biodiversity conservation—specifically, debt finance in the form of conventional bonds and impact bonds. The proceeds of these bonds finance projects aiming to enhance forest management, sustainable agriculture, endangered species protection, ecosystem service provision, and nature-based solutions to climate change such as REDD+. The article scrutinises whether these dual goals are achievable by evaluating the financial risks and impact risks within each bond's theory of change. Risks stem from projects with vague cashflow forecasts, project sites with low or ambiguous threat statuses, and simplified impact metrics that may measure activities or outputs—rather than impact. Risk mitigation strategies involve using baselines and counterfactuals to establish additionality, and guarantors to protect investors if revenues are insufficient. Implications for biodiversity management and for-profit conservation are discussed.     

混合型组织的可持续成长：多重紧张的战略响应

本文从混合型组织的“多重紧张识别-多重紧张影响效应-多重紧张的战略响应”这一逻辑链条出发，建构混合型组织紧张表现形式的钻石模型，识别出以使命紧张和制度紧张为表现形式的本源性紧张和以战略紧张、治理紧张、运营紧张和身份紧张为表现形式的引致性紧张。在此基础上，提出紧张度对混合型组织可持续成长影响效应的倒U型关系，认为恶性紧张容易引发单向性使命漂移、内外部合法性冲突、组织治理失灵、扩展性受限等组织脆弱性问题，良性紧张则可以激发组织创新性、促进制度逻辑重构并促进组织身份制度化，有利于组织的可持续成长。针对混合型组织出现的多重紧张，本文结合紧张度和混合元素性质认知两个维度，拓展性地提出针对“紧张”的适度竞争、适当激发、分离战略、整合战略和弹性战略五种响应战略，并基于紧张形式与组织类别建立针对恶性紧张的响应战略适配矩阵。     

Access to transportation,residential segregation,and economic opportunity

The Housing Choice Voucher Program assists low-income families to afford decent housing and provide them with better economic opportunities. There is growing evidence that public transportation plays an important role in shaping the residential location choices of low-income households. However, transportation has not been a major focus of the research related to housing voucher programs. We develop a general equilibrium model of a city with multiple districts, decentralized employment, multiple commuting modes, and locally financed education. We compare housing vouchers with transportation vouchers with respect to poverty deconcentration, educational quality in each district, unskilled employment in the suburbs, and welfare.     

Ecotourism branding in protected areas of Iran: Using an efficient hybrid multi-criteria decision-making method model

Ecotourism, as a nature-based sustainable tourism, raises awareness about the protection of natural and cultural landscape values. This study aims to determine the ecotourism criteria to develop strategies for a sustainable ecotourism branding in Golestan, located in the northeast of Iran. To reach this aim, Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis, multi-criteria decision-making methods consisting of Analytic Hierarchy Process (AHP), and Best and Worst Method (BWM) were integrated. The most appropriate ecotourism strategies for the branding of the study area were ranked according to their priorities. The results of this study reveal that among the 5 main and 20 sub ecotourism criteria, “having natural protected areas,” which is an opportunity, and “having ecological values,” which is a strength, were determined as the highest priority strategies for ecotourism branding. The methods and results of this quantitative-based research present an exemplary hybrid model that prioritizes the strategies required for branding ecotourism in similar protected areas.     

Innovation ecosystems as a service: Exploring the dynamics between corporates & start-ups in the context of a corporate coworking space

The desire to create innovative organizational spaces has led to various instantiations of innovation ecosystems. Towards this direction, there is a growing interest in establishing corporate innovation ecosystems in the form of ‘corporate coworking spaces’ (CWS). From a relational ontological standpoint, this study builds on the collaborative spaces literature with the aim to investigate the emerging dynamics between corporates and start-ups in an innovation ecosystem. Through an abductive research strategy (ARS) as well as service design methods, we explore how co-creation between corporates and start-ups emerges (or not) in an innovation ecosystem that serves as a collaborative space in Denmark. Our empirical findings challenge the mostly overenthusiastic connotations and thus the study contributes to the critical coworking research stream. More specifically, we give emphasis on the co-constructive entanglement of socio-spatial arrangements and we propose a framework for revisiting the design of CWS through 1) balancing the engineered and evolving parts of the ecosystem, 2) facilitating stakeholder alignment, 3) adopting a service-oriented approach and 4) developing inclusive strategies. Apart from the implications for scholars and practitioners who study and design CWS, we argue that future research would especially benefit from building on a service-oriented approach of innovation ecosystems and we call for more interdisciplinary research.
