The purpose of this paper is to present a novel image‐labeling CMOS sensor for modulated marker detection.

An image scene with multiple objects, each identified by a flashing light‐emitting diode (LED), is captured by the sensor. The LED's frequency is a representation of the object ID‐tag. The sensor detects and labels the objects by identifying the signal frequencies. The processing is performed in‐pixel and, since the object detection task is simplified, power dissipation is reduced. A 64×64 pixel sensor is designed in the 0.6 μm CMOS technology.

Simulation results show successful object identification. At a frame rate of 250 fps the measured power consumption is 11 mW, which is less than those of the previously reported object detection solutions. The application of the presented sensor is shown in several different robotic fields such as unmanned aerial vehicles (UAVs) vision, household robots and industrial robots. It is also explained how the sensor can be used for low‐power localization and position detection of the robot vehicles.

The paper shows that the sensor is a suitable solution for low‐power landmark detection and robot localization.

This paper aims to examine the effect of critical mass of women managers on corporate boards on the voluntary disclosure of climate change in a developing country in which the regulations on climate change disclosure is an area of growing research interest.

This study uses logistic panel regression models with a sample of 1,001 firm-years for companies in the Borsa Istanbul 100 Index that were asked to disclose voluntary climate change indicators over the seven-year period from 2014 to 2020 through the Carbon Disclosure Project.

This paper provides evidence from an emerging country that the critical mass of women on the board has no impact on voluntary climate change disclosure. In addition, the presence of independent managers on the board was found to have a significant impact on climate change disclosure. In addition, the results show that larger companies are more likely to report their climate change activities. Large companies are more visible due to their size, are perceived by stakeholders as more polluting and are, therefore, more likely to report on the environment.

The results show that the critical mass of women on the board has no effect on voluntary disclosure of climate change. Empirical tests are still needed to strengthen the overall validity of the critical mass of at least three women on boards in Türkiye.

Despite many valuable insights provided by critical mass theory, very few studies directly address critical mass and voluntary disclosure of climate change. To the best of the authors’ knowledge, this study is the first empirical and comprehensive paper in the Turkish context evaluating critical masses and voluntary corporate climate change giving a comparison between firms listed on financial industry and nonfinancial industry.

This study aims to examine how the effect of pop-ups on an omnichannel brand’s subsequent online sales is moderated by the brand’s online price and premium promotions, paid search and popularity signaling.

Using a difference-in-differences approach, this study appraises variations in two similar Chinese apparel brands’ online sales before and after one of the brands’ implementations of its pop-ups and how the brand’s online promotions modify the pop-ups’ effect.

Unique, interactive pop-ups boost brands’ subsequent online sales. Online price promotions negatively moderate the effect; online premium promotions and paid search positively moderate it. Moreover, the product’s popularity diminishes the extent to which a pop-up stimulates online demand. These findings can be partially generalized to other categories, such as utilitarian products.

Only certain online strategies enhance the effect of pop-ups on brands’ online sales, so practitioners should strategically select appropriate promotion combinations when they operate pop-ups and allocate resources across channels. In addition, the moderating influence of online promotions on pop-ups depends on the type of product being promoted.

Pop-ups offer proven abilities to deliver sensory experiences to online shoppers, reinforce brand awareness and loyalty and boost online sales. This study extends prior research by examining how various online promotions moderate pop-ups’ effects.

This study aims to examine the direct relationship between board gender diversity (BGD) and financial performance and the moderating role of corporate social responsibility (CSR) in the said relationship.

Using data collected from the Thomson Reuters Eikon ASSET4 database from 42 UK financial institutions listed in the ESG index for the period 2005–2019, this study used multivariate regression analysis on panel data to test the effect of BGD on financial performance and estimate the moderating effect of CSR between them. Moreover, to control the endogeneity problem, the authors conducted an additional analysis by testing the dynamic dimension of the data set through the generalized moment method.

The empirical results show that BGD is positively related to financial performance and that BGD increases firm performance with the moderating effect of CSR. Regarding the endogeneity problem, the existence of continuity between financial institution performances over time is demonstrated.

The current paper sheds light on the importance of BGD in improving firm performance and the moderating role of CSR in strengthening the relationship between BGD and firm performance, thereby contributing to the agency theory, the resource dependency theory and the stakeholder theory. Therefore, regulators and policymakers in the UK can use the outcomes of this study to enforce the representation of female directors on boards to enhance the financial performance of financial institutions. Moreover, the findings could be useful for regulatory bodies to encourage financial institutions to practice CSR activities and disclose them in their annual reports.

To the best of the authors’ knowledge, this is the first study investigating the moderating role of CSR on the relationship between BGD and financial performance in the context of the financial sector. It is also the first study documenting that CSR reinforces the relationship between gender-diverse boards and financial institutions' performance. This study fills a research gap as it expands the existing literature that has generally focused on the impact of BGD on financial performance and has not reached similar results.

The purpose of this paper is to examine the impact of the characteristics of two corporate governance mechanisms, namely, board of directors and ownership structure, on the firm value of European financial institutions.

Using the market-to-book ratio calculated by the Thomson Reuters Eikon ASSET4 database, this study measures the firm value of 111 financial institutions belonging to 12 European countries listed on the stock exchange during the period 2007–2019. Multivariate regression analysis on panel data is used to estimate the relationship between corporate governance attributes, such as board size, board independence, board gender diversity, ownership concentration and CEO ownership, and the firm value of European financial institutions.

The empirical results reveal that board gender diversity and CEO ownership are positively related to the firm value, whereas board size and ownership concentration are negatively related. Furthermore, the findings suggest that board independence is insignificantly correlated with the firm value. Regarding the control variables, the results show that financial institutions' size, age and legal system are significant factors in changing the firm value. Nevertheless, financial institutions' leverage and activity sector are not significantly correlated with their value.

This research contributes to the literature by providing the significant links between some corporate governance mechanisms and the firm value of companies from the financial industry, by addressing the information gap for this critical industry in the context of a developed market like Europe.

Google commands approximately 70 per cent of search market share worldwide, resulting in businesses investing heavily in search engine advertising on Google to target potential customers. Recently, Google changed the way in which content and ads were displayed on the search engine results page. This reshuffling of content and ads is expected to affect the advertisers who advertise on Google and/or use it to drive traffic to their websites. The purpose of this study is to analyze the impact of these changes on various stakeholders.

Data have been collected from various sources on the internet including blogs and discussion forums. Netnography has been used as it allows a detailed evaluation of the consumers’ needs, wants and choices in a virtual space.

The average cost-per-click for ads on the top positions is expected to increase. Advertisers whose ads usually occupy the lower positions would be adversely affected. To counter this, more emphasis should be placed on ad extensions and on product listing ads. In addition, organizations would benefit from increased efforts on search engine optimization.

A variety of coping strategies have been developed that can help marketers to successfully navigate through the change, including the use of ad extensions and the use of product listing ads.

This practice-focused paper offers guidelines for digital marketers to use sponsored search more effectively as part of their arsenal in light of some important changes recently made by Google. The potential of netnography as a research methodology has also been expanded by using it in a novel setting and in drawing up actionable insights.

There has been an increase in research examining whether and how companies disclose climate change impacts and how these disclosures influence capital structure strategies in recent years. However, prior literature has generally focused on developed countries. This paper proposes to examine the impact of voluntary climate change disclosures on corporate financing decisions in an emerging economy.

The dataset includes 335 firm-year observations listed in the Borsa Istanbul (BIST) 100 manufacturing industry firms that participated in the Carbon Disclosure Project (CDP) questionnaire from 2016 to 2020, characterized by high public awareness of greenhouse gas emissions in Turkey. To accomplish this aim, two models have been constructed that link capital structure strategies with voluntary corporate climate change disclosures while controlling for firm-level attributes in terms of size, profitability, market value and free float ratio (FFR).

The significant and negative relationship between the voluntary disclosure of climate-related activities and long-term borrowing is consistent with the arguments that companies with high commitments are unlikely to reduce default risk in emerging markets. This paper also provides empirical evidence that the high size and the level of low profitability magnify this relationship between CDP and financial leverage.

The Paris Agreement seems to be a significant point where corporate lenders have become aware of the commitment of policymakers to fight climate change. The results have significant implications for both managerial strategies and environmental regulatory policy-making issues. In addition, the findings shed light on the strategic behavior of managers in the consideration of climate change risks and related transparency.

This study aims to address the following research questions: Do the two types of service firms (individual or aggregator) have similar competitiveness on online search ads? How should the two types of service firms select optimal branded keywords to improve search performance? In addition, how do consumers’ search queries influence the service search performance of the two types of service firms?

In this study, the authors conduct an empirical analysis by building a two-stage choice modeling on the process of search engine ranking and consumer click-through decisions. The authors estimate the parameter coefficients and test the hypotheses using maximum likelihood estimation in the logistic regression model.

The empirical findings suggest that consumer response rates are highly dependent upon three aspects (service types, branded keyword strategy and consumer search query). First, the authors found that service aggregators receive greater consumer responses than individual service providers. Second, depending upon the various branded keyword strategies (e.g. generic vs branded, “within-type” vs “cross-type”) implemented by service aggregators or individual firms, the expected consumer responses could be quite different. Finally, customer’s search query, being either generic or branded, also has direct effect and interactive effect with service type on how consumers would response to the sponsored ads in the service search process.

The limitation of the research is twofold. First, conversion rate is not considered in the model estimation due to the nature of the data set. Second, the discussion about the keywords selection strategies is focusing on the hospitality industry. Future research shall further validate the generalizability into other industries.

First, given this competitive advantage, service aggregators should take an aggressive approach to adopting paid search strategy in acquiring new users and enhance its brand salience in the service ecosystem. Second, when considering other competitor’s brand names to include, if a firm is a service provider (e.g. hotel), a strategy that can help it receive higher consumer response would be to use “within-type” rather than “cross-type” branded keyword strategy. If a firm is a service aggregator, a better branded keyword strategy would be to use “across-type” instead of “within-type” approach. In addition, given that consumer’s brand awareness can influence the effectiveness of branded keyword strategy, online service search should target consumers in earlier stages of a decision journey.

The authors believe their theoretical framework can provide actionable solutions to service firms to ease customer’s search process, increase customer’s stickiness using search engines and add value to the customer relationships with all services entities within the digital ecosystem.

This study is the first to expand online search marketing into granule examinations (main and interactive effects of three key factors) in the service search domain. First, the authors differentiate service firms into two categories – online travel aggregators and individual hotels in the model. Second, the authors introduce two sets of new classifications of branded keywords for online service search research (i.e. own versus other brand and “cross-type” versus “within-type” branded keywords). Third, this study integrates service consumers’ search word specificity into the conceptual framework which is often missing in previous online search research.

After discussing this case, students will be able to understand the challenges faced by social entrepreneurs in starting a health-tech start-up in Africa; create and evaluate lean business models of health-tech companies as a social enterprise; evaluate how health-tech start-ups were developing innovative business models and supply chain networks to make prescription drugs accessible and available in Africa; understand how inorganic growth strategies can help health-tech start-ups scale up; and evaluate what promises investors were seeing while investing in social enterprises in the health-care sector in Africa and what social wealth they were creating.

In August 2022, Gregory Rockson (Rockson), social entrepreneur and founder of for-profit health technology (health-tech) social enterprise in Ghana, mPharma, stated that he had plans to replicate the company’s business model, which provided people access to drugs and at affordable prices, to other African nations, beyond the company’s existing footprint. However, analysts pointed out that the fragmented drug supply chain and poor regulation in the health-care market across Africa could act as a challenge for mPharma to replicate its business model successfully across the African continent. People in Africa were forced to pay higher prices to buy life-saving drugs due to the continent’s fragmented drug supply chain. To add to their woes, pharmacies struggled to keep life-saving and life-sustaining medicines in stock. Often, patients traveled miles to a pharmacy only to find out that the drugs they needed were not in stock. In addition to this, the markets were flooded with counterfeit drugs. And the Covid-19 pandemic only exacerbated the situation. mPharma managed the prescription drug inventory for pharmacies and drug suppliers using its proprietary vendor management information system. By using the technology infrastructure it had built, the company connected patients, pharmacies and hospitals through a cloud-based software. The system enabled doctors to track in real-time which drugs were available and at which location, thus giving patients reliable access to medicines. Patients registering with mPharma with their prescriptions and medical history received an alert on their mobile phones notifying them where the drugs they needed were available. mPharma bought drugs from major drug manufacturers such as Novartis International AG, Pfizer Inc. (Pfizer) and Bayer AG, on behalf of the pharmacies. This enabled the pharmacies to save on the up-front costs of stocking the drugs, reduced supply constraints and ensured availability of drugs to consumers in these underserved markets. The company had a consignment model wherein member pharmacies had to pay only for what they sold. Most pharmacies forecast the number of drugs they needed and purchased them from mPharma at pre-agreed rates. The company took the inventory liability to prevent pharmacies from going out of stock. As mPharma used its purchasing power to buy drugs in large quantities from drug manufacturers and suppliers, it was able to help patients realize cost savings of 30% to 60% in the purchase of medicines. mPharma was focusing on achieving its ambitious goal of dominating the health-care market in Africa in future. However, analysts felt that the company would face challenges related to poor regulation in the health-care market, high prices of drugs and the fragmented pharmacy retail market in the continent.

Much work about health reform and systems improvement in healthcare looks at shortcomings and universal problems facing health systems, but rarely are accomplishments dissected and analyzed internationally. The purpose of this paper is to address this knowledge gap by examining the lessons learned from health system reform and improvement efforts in 60 countries.

In total, 60 low-, middle- and high-income countries provided a case study of successful health reform, which was gathered into a compendium as a recently published book. Here, the extensive source material was re-examined through inductive content analysis to derive broad themes of systems change internationally.

Nine themes were identified: improving policy, coverage and governance; enhancing the quality of care; keeping patients safe; regulating standards and accreditation; organizing care at the macro-level; organizing care at the meso- and micro-level; developing workforces and resources; harnessing technology and IT; and making collaboratives and partnerships work.

These themes provide a model of what constitutes successful systems change across a wide sample of health systems, offering a store of knowledge about how reformers and improvement initiators achieve their goals.

Few comparative international studies of health systems include a sufficiently wide selection of low-, middle- and high-income countries in their analysis. This paper provides a more balanced approach to consider where achievements are being made across healthcare, and what we can do to replicate and spread successful examples of systems change internationally.
