- Introduction: Ectopic parathyroid adenoma is rare during pregnancy but poses multiple challenges in treatment. It presents as primary hyperparathyroidism which leads to symptoms and complications of hypercalcemia in both the mother and fetus. Presentation of case: A 38-year-old Sudanese female presented with diffuse bone pain and polyuria. Laboratory investigations revealed elevated serum calcium and parathyroid hormone. Ultrasound of the neck did not show any abnormal lesion, however 99mTc-sestamibi scan showed a right sided parathyroid adenoma, and an earlier CT scan showed the adenoma to be in an ectopic paraesophageal position. Focused surgical neck exploration was done, and the ectopic parathyroid adenoma was excised. Discussion: Preoperative localization of the ectopic parathyroid adenoma allows for a focused surgical procedure. Ultrasound is the safest during pregnancy, but 99mTc-sestamibi and CT scan may be necessary if ultrasound or initial bilateral neck exploration do not detect any adenoma. Mild elevations in maternal serum calcium can have detrimental effects on the fetus which suggests that a surgical approach may be necessary in the majority of cases. Conclusions: Ectopic parathyroid adenoma is rare during pregnancy and is detrimental to both the mother and fetus. Preoperative localization allows for a focused surgery which is a definitive treatment and can safely be performed during the 2nd trimester of pregnancy.

- Emerging digital and smart technologies, including wearable and collaborative ones, related to the Industry 4.0 paradigm are playing an assisting, collaborative, and augmenting role for the Operator 4.0, and just as in previous industrial revolutions, the nature of work and the workplace for operators on the shop floor is changing. This literature review aims to look into the impact of digital and smart technologies adoption on the workers’ psychosocial stage under the light of the Operator 4.0 typology. Based on the review conducted, a theoretical framework for assessing the psychosocial impacts (risks) of Industry 4.0 technologies adoption in Operator 4.0 is proposed. The framework can be utilized by company managers, researchers, production engineers, and human resources personnel for carrying out a psychosocial risk assessment of Operator 4.0 in assembly, maintenance, and training operations as these operations get digitally transformed and smartified based on self-report questionnaires. Findings reveal that the nature of work, the social and organizational environment of work, and related individual factors are key categories that might affect the Operator 4.0 psychosocial stage on the shop floor.

- 2024
-
Ingår i: International Journal of Bank Marketing. - : Emerald Group Publishing Limited. - 0265-2323 .- 1758-5937.
-
Forskningsöversikt (refereegranskat)abstract
- Purpose: Financial anxiety has become a global concern and a growing research area with significant potential to contribute to the behavioral and personal finance literature. Despite this, the literature is fragmented and inconsistent. Prior studies vary greatly in the breadth of definitions and measures of financial anxiety. There has been no systematic evaluation of literature on financial anxiety antecedents, consequences, and coping strategies. This systematic review fills this gap. Design/methodology/approach: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched Scopus and Web of Science and identified 55 eligible studies published between 2009 and 2024. Findings: Financial anxiety is defined and measured differently in different research domains. We identified several antecedents, including socio-demographic factors (e.g. gender, age, ethnicity, income, employment, racial background, and language proficiency), personality traits, compulsive and impulsive buying behavior, depression or other mental issues, family health issues, and the COVID-19 pandemic and consequences of financial anxiety, including psychological and psychic health, societal and personal relations, financial behavior and well-being, and job-related outcomes. In addition, the literature presents six financial anxiety coping strategies (self-imposed coping mechanisms, spiritual and theological resources, increased financial capability, social and family support, seeking professional help, and language proficiency training). Several future research directions are presented. Originality/value: This review represents the first systematic compilation and evaluation of the research findings on financial anxiety.

- Stevia is a perennial herb that belongs to the Asteraceae family. It is a natural sweetener plant and estimated to be 300 times sweeter than cane sugar. The leaves of stevia are the source of diterpene glycosides, viz. stevioside and rebaudioside. Stevioside is regenerated as a valuable natural sweetening agent because of its relatively good taste and chemical stability. Now it is being cultivated in Japan, Taiwan, Philippines, Hawaii, Malaysia and overall South America for food and pharmaceutical products. Products can be added to tea and coffee, cooked or baked goods, processed foods and beverages, fruit juices,

Forskningsöversikt (refereegranskat)abstract
- Background: Foam rolling has been extensively investigated, showing benefits in performance and recovery. Recently, vibration has been added to foam rollers, with hypothesized advantages over conventional foam rollers. However, there is no systematic evidence in this regard.Objective: To carry out a systematic review and meta-analysis about the effects of vibration foam roller (VFR) on performance and recovery.Methods: A systematic search was conducted in PubMed/MEDLINE, Web of Science and SportDiscus according to the PRISMA guidelines. The outcomes included performance (jump, agility and strength) and recovery variables (blood flow, pain and fatigue) measured after an intervention with VFR. The methodological quality was assessed with the PEDro scale. A random-effects model was used to perform the meta-analysis.Results: Initially, 556 studies were found and after the eligibility criteria 10 studies were included in the systematic review and 9 in the meta-analysis. There was no significant effects on jump performance (SMD = 0.14 [95% CI − 0.022 to 0.307]; p = 0.101; I2 = 1.08%) and no significant beneficial effects were reported on isokinetic strength (SMD = 0.16 [95% CI − 0.041 to 0.367]; p = 0.117; I2 = 9.7%). Recovery appears to be enhanced after VFR interventions, but agility does not seem to increase after VFR interventions.Conclusion: This systematic review and meta-analysis suggest that VFR could have great potential for increasing jump performance, agility, strength and enhancing recovery. Further research is needed to confirm the effects of VFR on performance and recovery.Trial Registration This investigation was registered in PROSPERO with the code CRD42021238104.

A critical examination of the EO-performance relationship
- 2010
-
Ingår i: International Journal of Entrepreneurial Behaviour & Research. - Bingley, United Kingdom : Emerald Group Publishing Limited. - 1355-2554 .- 1758-6534. ; 16:4, s. 309-328
-
Forskningsöversikt (refereegranskat)abstract
- Purpose: The purpose of this study is to critically analyze the assertion that there is a statistical significant relationship between EO and performance.Design: In several publications it has been stated that there is a positive relationship between entrepreneurial orientation (EO) and the performance of a firm. These studies have generally used the same core references, and these seminal contributions are examined critically in this article. The EO-performance relationship is also analyzed in an empirical study, consisting of 172 Swedish SMEs in the manufacturing sector.Findings: The result of the literature review is that the notion of a positive EO-performance relationship can be questioned. Earlier studies have neglected some important issues, mainly regarding the use of perceptual performance data, common method biases and survival biases. Some of the conclusions presented are supported by the empirical study.Originality/value: The main point of this paper is to show that the relationship between EO and performance is more complicated than previous studies have implied. More care should be taken when generalizing the results of core references and scholars ought to have a more cautious approach when stating that there is a general correlation between EO and performance.

Forskningsöversikt (refereegranskat)abstract
- Purpose: The aim of this article is to provide a holistic framework for the acquisition of strategic resources.Design/methodology/approach: The literature dealing with resource creation is reviewed and analyzed from a resource-based point of view. The major methods of acquiring resources are identified through the literature review and the applicability of the framework proposed is illustrated with an empirical example.Findings: Three ways of acquiring strategic resources are identified-- direct investments, organizational processes, and product market positioning. All three ways of acquisition can be intentional or unintentional. Arguments for using this six-dimension scale are provided through deductive reasoning, literature review, and the empirical example.Research implications/limitations: The study identifies the six dimensions of strategic resource acquisition. However, integration of these dimensions is not a subject addressed in this study. Cluster analysis of companies according to these dimensions could enhance our understanding of the characteristics of companies regarding resource acquisition.Originality/value: Whereas previous studies have generally used a single-theory approach, this study highlights the importance of having a holistic outlook when analyzing resource-based competitive advantages.

Forskningsöversikt (refereegranskat)abstract
- Purpose: Numerous studies have set out to examine the relationship between strategic resources and firm performance. The traditional VRIO attributes have been the point of departure in most resource-based studies. This paper sets out to argue that the relationship between resources and performance is more complex. Thus, the purpose of this paper is to illustrate the complex relationship between a strategic resource and firm performance by providing an overview of different factors that can influence this relationship.Design/methodology/approach: Relevant literature is reviewed and discussed.Findings: It was found that five criteria must be fulfilled for resources to generate superior performance. These are identified and discussed. These criteria fit with existing resources, management capability, marketing capability, firm appropriation of rent, and non-competitive disadvantages.Research limitations/implications: By using the criteria identified, resource-based theory can become less tautological. Also, the criteria highlight the importance of resource utilization and appropriation of resource-based rents.Practical implications: The paper could contribute to an increased awareness among practitioners of the importance of focusing on factors which are additional to the VRIO-attributes when analyzing potential strategic resources. The criteria provide an easy-to-access framework for strategic analysis.Originality/value: Whereas some specific aspects of the relationship between the possession of resources and firm performance have been reviewed in some RBT contributions, few studies have addressed the issue using a more holistic approach. Thus, this paper affords a broader approach on the relationship between strategic resources and firm performance.

- Collections of time series formed via aggregation are prevalent in many fields. These are commonly referred to as hierarchical time series and may be constructed cross-sectionally across different variables, temporally by aggregating a single series at different frequencies, or even generalised beyond aggregation as time series that respect linear constraints. When forecasting such time series, a desirable condition is for forecasts to be coherent: to respect the constraints. The past decades have seen substantial growth in this field with the development of reconciliation methods that ensure coherent forecasts and improve forecast accuracy. This paper serves as a comprehensive review of forecast reconciliation and an entry point for researchers and practitioners dealing with hierarchical time series. The scope of the article includes perspectives on forecast reconciliation from machine learning, Bayesian statistics and probabilistic forecasting, as well as applications in economics, energy, tourism, retail demand and demography.

Data mining methods for knowledge discovery in multi-objective optimization : Part A - Survey
- 2017

- Real-world optimization problems typically involve multiple objectives to be optimized simultaneously under multiple constraints and with respect to several variables. While multi-objective optimization itself can be a challenging task, equally difficult is the ability to make sense of the obtained solutions. In this two-part paper, we deal with data mining methods that can be applied to extract knowledge about multi-objective optimization problems from the solutions generated during optimization. This knowledge is expected to provide deeper insights about the problem to the decision maker, in addition to assisting the optimization process in future design iterations through an expert system. The current paper surveys several existing data mining methods and classifies them by methodology and type of knowledge discovered. Most of these methods come from the domain of exploratory data analysis and can be applied to any multivariate data. We specifically look at methods that can generate explicit knowledge in a machine-usable form. A framework for knowledge-driven optimization is proposed, which involves both online and offline elements of knowledge discovery. One of the conclusions of this survey is that while there are a number of data mining methods that can deal with data involving continuous variables, only a few ad hoc methods exist that can provide explicit knowledge when the variables involved are of a discrete nature. Part B of this paper proposes new techniques that can be used with such datasets and applies them to discrete variable multi-objective problems related to production systems.
