This empirical study aims to explore sufficiency conditions for patient loyalty to a hospital.

The study collected 645 self-administered questionnaires from patients in a major medical center in Taiwan and applied fuzzy set qualitative comparative analysis (fs/QCA) to explore the sufficiency conditions for patient loyalty.

The findings support the conclusion that the three conditions (patient satisfaction, patient participation in the process of diagnosis, and patient participation in treatment decision-making) in combination are sufficient for high patient loyalty to the hospital but high patient satisfaction alone is insufficient. While the three conditions in configural algorithm are sufficient, this expression is not necessary, which means the findings do not reject possible alternative conditions for high patient loyalty.

The study applies a relatively new method, fuzzy set qualitative comparative analysis (fs/QCA) to test the sufficiency proposition of the theory. This method enables researchers to focus on examining sufficient conditions without worrying about various confounding factors and informs this study ' s conclusion that patients exhibiting high scores in all three conditions mentioned above constitute a near-perfect subset of highly loyal patients. Hospitals thus should provide their satisfied patients opportunities to share a role in the process of diagnosis and treatment decision-making.

Along with patient satisfaction, this study clearly identifies two important stages of patient participation (i.e., participation in the process of diagnosis and treatment decision-making) that are important in forming patient loyalty to a hospital. Prior studies do not present empirical evidence to this proposition.

Living a nutritious lifestyle requires that people get a sufficient amount of nutrients, vitamins and minerals every day. Healthy dietary practices are related to a stronger immune system, better prevention and easier recovery from illnesses, lower blood pressure, healthy weight, lower risk of diabetes, heart problems and other medical conditions and improved overall well-being (WHO, 2020). Therefore, to maintain a strong immune system able to prevent diseases and ease recovery, optimal nutrition and healthy habits are of increased importance during a pandemic such as Covid-19. However, according to the Bureau of Labor Statistics, more than 22 million Americans have lost a job between February and October 2020, increasing the unemployment rate from 3.5% in February 2020 to 6.9% in October 2020, reaching a peak of 14.7% in April 2020. Job losses during the Covid-19 crisis are likely to put lots of families at risk of malnutrition and food insufficiency and to further deteriorate the already existing food insecurity (Gundersen et al., 2018). This research explores the effect of a recent job loss between August and October 2020 on food sufficiency.

This research examines the impact of a job loss on nutrition and food safety. Specifically, this study explores the effect of a job loss during the Covid-19 pandemic on the level of family and child food sufficiency as perceived by the respondent, confidence about meeting family’s dietary needs in the four weeks following the interview, and an indicator of whether the food sufficiency status of the family has deteriorated or not. This study also determines the differential effect of a job loss by individuals who are still employed despite the loss relative to workers who remained unemployed after a job loss during the Covid-19 crisis. Subsample analyses based on ethnicities, genders and educational attainment are also performed to identify the most vulnerable groups.

The results provide evidence that a job loss is associated with a highly statistically significant deterioration of food sufficiency for families and children and a reduction in the confidence in food security for the near future. This effect is observed for all job losers, but from them, it is larger for the ones who are currently unemployed compared to those who are working. The association between a job loss and family’s nutrition insecurity is the greatest for Hispanic, males and people with some college. Children’s nutrition suffers the most for children whose parents have not completed high school. These results provide an insight into the adverse effect of Covid-19 on food security.

From a policy perspective, the results indicate that federal nutrition programs whose goal is to ensure that the dietary needs of Americans, and especially children, are met, which are most likely to benefit the Hispanic population, individuals with low educational attainment and individuals who remained unemployed after losing a job.

This study makes several contributions to the growing literature on food security. First, this study is novel in that it examines the effect of an ongoing event, specifically a labor market disruption as a result of a health and economic crisis, on families’ nutrition, and does so using the newest publicly available data designed to track the impact of Covid-19 on the American population. This is one of the first studies that investigates the forementioned impacts in the context of the Covid-19 pandemic. This study further contributes to the literature by distinguishing between employed versus unemployed individuals despite a job loss and by studying distinct groups on the population. In addition, this study compares the effects of interest in the onset of the pandemic to a year later to examine the population’s adjustment to the crisis. The importance and relevance of the results for policy decision-making are also discussed in the paper.

The purpose of this paper is to empirically study the necessary and sufficient antecedents of customer loyalty to logistics service providers (LSPs). Despite the abundance of loyalty studies, few studies have empirically examined the complex causal relationships between loyalty and its antecedents using the appropriate research methods.

The study uses fuzzy sets qualitative comparison analysis (FsQCA) to uncover the antecedents and antecedent configurations of customer loyalty. This study examined the necessity and sufficiency of five antecedents (operational collaboration, strategic collaboration, trust, service satisfaction and price satisfaction) and on five dimensions of loyalty (repurchase intension, switching costs, exclusiveness, referrals and overall loyalty). This study developed six research hypotheses based on existing literature and tested them empirically in a manufacturing context. This study compared results from FsQCA with regression analysis.

The findings reveal that only a few antecedent configurations lead to customer loyalty, including a combination of strategic and operational collaboration, bundling of service offerings and combining competitive price with strategic collaboration. Further, the absence of trust negatively affects loyalty, but the presence of trust does not lead to loyalty.

This study contributes to business to business literature by demonstrating how to use FsQCA analysis to test the presence of equifinality, conjunction and causal asymmetry of complex relationships. This study applies FsQCA between antecedent factors and customer loyalty. Furthermore, we demonstrate how to compare and integrate FsQCA with conventional regression analysis which is based on correlation-bounded logic.

This study shows that no single antecedents that can generate loyalty, yet, few antecedent configurations work better than others: collaborating at both strategic and operational level with your partner has the highest impact on loyalty. Another configuration that leads to loyalty is to combine competitive prices with strategic collaboration, which particularly stimulates repurchase decisions. Price is are not sufficient enough to lead to customer loyalty.

This study applied a novel analysis to uncover necessary and sufficient conditions that conventional methods such as regression analysis and structural equation modelling have limited power.

Social and environmental accounting research manifests varying levels of awareness of critical global problems and the need to develop alternative approaches to dealing with economy and society. This paper explores Buddhist thought and, specifically, Buddhist economics as a means to informing this debate. We draw on and expand Schumacher's ideas about ‘Buddhist economics’, first articulated in the 1960s. Our analysis centres on Buddhism's Four Noble Truths, the Noble Eightfold Path and associated Buddhist teachings. The examination includes assumptions, means and ends of Buddhist approaches to economics; these are compared and contrasted with conventional economics.To consider how thought and practice may be bridged, we examine a practical application of Buddhism's Middle Way, in the form of Thailand's current work with ‘Sufficiency Economy’.Throughout the paper, we explore the implications for the development of social accounting, looking for mutual interactions between Buddhism and social accounting thought and practice.

Sharing resources with stakeholders is the key for keystones to govern business ecosystems successfully. However, existing research has not paid further attention to how keystones share resources under the condition of resource sufficiency and how keystones balance resource sharing with complementors when they lack resources. Therefore, this paper aims to explore how keystones govern their business ecosystems under the conditions of resource sufficiency and resource insufficiency.

This paper adopts the single case study method. First, by adopting Gioia coding to analyze the relevant data of the case sample, this paper obtains the key concepts of the business ecosystem governance process. Then, it establishes the relationship between the concepts by analyzing the governance process of the case sample.

Under the condition of resource sufficiency, keystones under the condition of resource sufficiency, should make full use of resources to incubate more complementors, and further integrate the resources of the business ecosystem, to create more value for their business ecosystems. Under the condition of resource insufficiency, keystones should break the boundaries of business ecosystems and acquire external resources, to meet the resource needs of complementors. Subsequently, keystones should redeploy idle resources according to the actual needs of complementors, to meet the changing resource needs of complementors.

This study subdivides business ecosystem governance conditions and further constructs the business ecosystem governance process model, which provides a theoretical and practical reference for business ecosystem governance.

The authors illustrate accounting information's effects in terms of necessity and sufficiency, using a set-theoretic approach, and highlight how the approach complements conventional correlational analyses.

The authors examine the relationship between accounting numbers (accounting information) and stock prices (effect) under both correlational and set-theoretic perspectives using a value relevance methodology.

The claim that accounting information is significantly correlated to an outcome does not inform the accounting information's necessity or sufficiency. In addition, findings suggest that not all control variables that are significantly correlated to a supposed accounting effect are necessary to explain that effect. Moreover, variables reflecting accounting information are not individually sufficient to explain the effect under investigation.

The study contributes to set-theoretic approach to accounting research and echoes the call for a diversity of research approaches in accounting.

The study may have practical implications for various accounting information users, including investors, financial analysts and financial market and accounting disclosure regulators as well. Indeed, accounting information users should consider the importance of the combined effect of multiple pieces of accounting information in the users' positions on firms' stocks. Understanding what might be the relevant combinations of accounting information associated with a given organizational context is a key in making compelling accounting-informed decisions. Such knowledge can inform reflections of accounting disclosures and regulations on the combined effects of several accounting information.

First, the study adds to the newly introduced set-theoretic approach to empirical accounting. The study also resonates with the call for a diversity of research approaches in accounting. The authors empirically demonstrate that significant correlation between accounting information and its effects does not connote “necessity” or “sufficiency,” which is rather revealed by qualitative comparative analysis (QCA). Such complementarity can help accounting researchers to carry out (1) new investigations of accounting's earlier hypotheses or propositions and (2) investigations of new accounting hypotheses/propositions deriving from existing accounting theories and (3) to explore new relationships between accounting phenomena. Second, the study incidentally contributes to value relevance literature in terms of contextualization of the relevance of accounting information. Specific to the African capital markets, the study complements the few recent studies on the Bourse Régionale des Valeurs Mobilières d’Abidjan (BRVM).

The aim of this chapter is to introduce a methodology that enables researchers to employ a set of systematic comparative tools and techniques in their multiple case study research that allow them to move from drawing loose comparisons towards a more formalised type of analysis, while simultaneously paying attention to within-case complexities. This methodology stands between the qualitative and the quantitative methods and helps researchers to build middle-range theories (Mjoset, 2001) from small to intermediate numbers of cases. This methodology encompasses a number of techniques including crisp and fuzzy set-theoretic qualitative comparative analyses, which have been used in a wide range of social science disciplines. However, these techniques have not received sufficient attention from higher education scholars.

For firms entering a foreign market for the first time, institutional distance can be thought of as being insufficient in the sense that knowledge gap issues associated with large distances are not easily resolved. The purpose of this paper is to explore the concept of knowledge sufficiency and the implications that this concept holds for assuaging these issues.

The concept of knowledge sufficiency is developed into a practical framework. The framework is comprised of the knowledge that firms accumulate about potential host countries. This accumulated knowledge is disaggregated into components that provide the basic structure of the knowledge sufficiency framework and facilitate a systematic assessment of accumulated knowledge.

Accumulated knowledge about foreign market risk factors that exist in potential host countries is disaggregated into three components. The breadth of knowledge component is designed to help answer the question: what do firms know about foreign market risk factors in potential host countries? The depth of knowledge component is designed to help answer the question: how much do firms know about foreign market risk factors in potential host countries. The quality of knowledge component is designed to answer the question: are firms confident in what they know about foreign market risk factors in potential host countries?

There is a tendency for strategic decision makers in firms to feel that they have “deep” knowledge of foreign market risk factors when they may actually have only “surface” knowledge of these factors. The result is likely to be an unwarranted lowering of the risk they perceive to exist in potential host countries. Consequently, the host country selected for entry may not be optimal and the mode of entry may be inappropriate. The issue to be resolved is how to ascertain how much knowledge firms actually possess about these foreign market risk factors.

Selecting the “right” foreign market and entering that market in the “right” way is unquestionably one of the most important topics in the international literature and has been extensively studied. However, there is no central repository of finding from these studies that will help firms going international for the first time to systematically assess whether their choice of market and entry mode is optimal. Utilization of the knowledge sufficiency framework will significantly improve firms’ chances of entering the “right” foreign markets in the “right” way, which holds practical implications for their initial and long-term performance in these markets.

For firms entering a foreign market for the first time, answers to two questions are essential: what foreign market should we enter? How should we enter that foreign market? The extant literature does not provide a framework that allows firms to systematically search for answers to these questions such that, when satisfactorily found, will boost confidence that answers to these two questions are optimized. In addition to filling an important gap in the extant literature, the framework's usefulness as an aid for making internationalization decisions also makes an important contribution to practice.

Purpose – This chapter examines the complex, multilevel barriers low-income women of color in a medium-sized Midwestern city face when trying to achieve economic self-sufficiency and homeownership. The aim of this study was to determine whether women attempting to achieve self-sufficiency and/or homeownership face different barriers than men as a result of multiple and intersecting social locations.

Design/methodology/approach – The study sample includes 24 low-income women of color, all of whom participated in in-depth interviews in Fall, 2008. Low-income women also completed short demographic surveys. Intersectionality represents the conceptual framework for this study, and data analysis followed phenomenological inquiry.

Findings – Some barriers low-income women of color face are unacknowledged and are gendered and racialized. Many women in this study faced personal barriers (e.g., low-income, lack of savings, poor credit, lack of mentors) and system-level barriers (e.g., banking account requirements and lenders’ downpayment requirements) to obtain economic self-sufficiency and/or homeownership simultaneously.

Research limitations – This study only examined 25 women's experiences in one location. These findings can only be generalized to low-income women of color in this study.

Originality/value – This study addresses the gaps in existing literature about low-income women's journeys toward economic self-sufficiency, and highlights that many women have goals of homeownership as well. Data analyzed here also illustrated the complex nature of barriers.

In this paper, the authors aim to present a novel methodological tool – necessary condition analysis (NCA) to aid managerial psychology researchers in properly testing necessity statements.

The authors employ NCA to analyze whether three basic psychological needs for autonomy, competence and relatedness are necessary for work engagement.

The authors illustrate the value and application of NCA by revealing that basic psychological needs for autonomy, competence and relatedness are necessary for work engagement, as proposed by self-determination theory (SDT).

The authors illustrate the importance of the sufficiency-necessity distinction and the relevance of a necessity logic in managerial psychology. They also discuss NCA's methodological implications for managerial psychology research, theory and practice.
