What makes activities strategic: Toward a new framework for strategy‐as‐practice research

AbstractResearch AbstractStrategy as practice is one of the most vibrant approaches to strategy research. Yet, there is significant ambiguity around what characterizes an activity as strategic and thus as falling into the domain of strategy as practice. In this article, we address this fundamental concern by differentiating four distinctive views of what qualifies activities as strategic: (1) activities that have important consequences, (2) activities that are labeled strategic, (3) activities carried out by strategists, and (4) activities that perform an important recurrent pattern. Each of these views is associated with different research questions resulting in different research insights. We discuss how the four views together form a new research framework that expands the notion of strategy and thereby the research domain of strategic management.Managerial SummaryStrategy as practice is an important approach to studying strategic management that focuses on strategic activities. However, there is significant ambiguity around what characterizes activities as strategic. In this article, we identify four different views on this question: (1) activities that have important consequences, (2) activities that are labeled strategic, (3) activities carried out by strategists, and (4) activities that perform an important recurrent pattern of activities. Each of these views is associated with different questions and thus with different types of insights. We suggest that the four views together form a research framework that reveals distinctive links between strategy as practice and other lines of strategy research and that expands our notion of strategy and thereby the domain of strategic management.

Psychology of religion and spirituality in Jewish contexts: A synthetic review

Jewish spirituality and religion include dynamics that are different from other traditions and have important implications for relational forms of spirituality. Certain approaches to relational Judaism (e.g. Mussar) have offered insights for understanding the folk psychology of relational spirituality in Jewish contexts but have not generated empirical research. Existing research in the psychology of Jewish religion and spirituality draws on several theoretical frameworks and has generated helpful findings. In this synthetic review, we foreground the role of theory in psychological research and offer a brief review of several theoretical frameworks used in research on the psychology of Jewish religion and spirituality (cognitive-behavioral, psychodynamic, cultural psychology of religion, and positive psychology). The relational spirituality model (RSM) is summarized as a conceptual framework that could be useful for future research in this area. We use the RSM as a heuristic organizing framework to review several lines of prior empirical research on the psychology of Jewish religion and spirituality that fit within the RSM domains of spiritual dwelling, seeking, and struggles. The final section outlines future directions in research in this area based on the RSM, with particular attention to dimensions of diversity (e.g. gender, sexual orientation), diverse contexts of Jewish spirituality, Jewish spirituality in relation to both mental health suffering and flourishing, and historical trauma. We also highlight the need for research on Jewish spiritual development in communal settings (e.g. congregations, seminaries) to provide a deeper understanding at both individual and communal levels, and interdisciplinary integration with Jewish theology.

Thoracic ultrasound: a review of the state-of-the-art.

Thoracic ultrasound (TUS) is a tool that has become increasingly essential in the daily practice of thoracic medicine. Driven by the need to assess patients during the COVID-19 pandemic, there has been an increase in the use of point-of-care TUS, which has demonstrated several benefits, either as a complement to clinical decision-making for diagnosis or as a real-time guide for procedures, whether as a predictor or measure of treatment response. Here, we present a review of TUS, based on the most recent scientific evidence, from equipment and techniques to the fundamentals of pulmonary ultrasound, describing normal and pathological findings, as well as focusing on the management of lung disease and guidance for invasive thoracic procedures at the bedside. Finally, we highlight areas of perspective and potential lines of research to maintain interest in this valuable tool, in order to improve the diagnostic process and expand the treatment arsenal.

Emociones morales, revelación de la identidad personal y evidencia del corazón

Moral emotions show or reveal in some way the personal identity of their subject. Joy in the face of another's evil, sincere regret for having inflicted an objective evil on another person, hope in the face of a difficult situation, humility in facing one's own failure, etc., say a lot about the person who is the subject of these experiences. How do these affective experiences that we call "moral emotions" tell us or "give" us personal identity? In this order of things, I would like to present the central lines of the treatment of this question by the North American philosopher Anthony Steinbock. The perspective that this author adopts is phenomenological. By this I mean that it is not so much a question of the construction of personal identity by the subject and the "sediment" that moral emotions leave in him, but rather how this personal identity is given in moral emotions. At the end of my contribution I will offer some critical consideration of Steinbock's analyses and suggest new lines of research.

Review of previous works on functionally graded materials (FGM)

This paper presents bibliographical research on previous works of FGM functional gradient materials. We notice that functional gradient materials represent a relatively new line of research. Since the appearance of the FGM concept, many researchers have been interested in it, and countless works have been published, but there is still much to be done.

Líneas de investigación y perspectivas futuras de los estudios organizacionales: una revisión

Organizational studies allow us to analyze and understand the functioning of organizations, generate knowledge and improve their management and performance, from perspectives different from the classic ones with which the organizational phenomenon has been analyzed in a traditional way; These perspectives invite a critical look at this phenomenon. However, it is relevant to evaluate its potential to provide theories, models and tools that help advance the field of management and improve the effectiveness and sustainability of organizations. To date, no review has been identified in Scopus that synthesizes the literature on organizational studies from a bibliometric analysis, by doing so, this article provides a basis for researchers in organizational studies to learn about various future lines of research. The objective of this document is to review scientific documents published in Scopus(r) on organizational studies, to propose a structure of published scientific knowledge, so that different future lines of research are offered. 1091 documents were found that met the inclusion and exclusion criteria in the database that were processed with Bibliometrix, VosViewer and ToS. The main lines of research identified were: a) Leadership and management of organizational change; b) Changing, diverse and inclusive work environments; c) Legitimation, sustainability and organizational responsibility.

A framework for territorial spatial ecological restoration zoning integrating “Carbon neutrality” and “Human-geology-ecology”: Theory and application

Global climate change worsens the imbalance among human environment, geological environment and ecological environment (human-geology-ecology), leading to increasingly prominent ecosystem damage. Constructing a scientifically effective territorial spatial ecological restoration zoning (TSERZ) framework will promote the coordination between nature and human. However, the fundamental role of geological environment in TSERZ has been overlooked, and there is lack of theoretical frameworks and empirical research on TSERZ oriented towards carbon neutrality goal. Therefore, we have proposed a new TSERZ framework by integrating “carbon neutrality” and “human-geology-ecology”, which employs models such as CECM, LCA, IUEMS and ESP to divide primary zones, secondary zones and key areas, and also provides restoration directions for various zones. Taking the typical alpine-gorge region of Yulong County as an example, we conduct empirical research to verify the validity of the TSERZ framework. The findings indicate that, firstly, besides human and ecological factors, geological factors like lithology are indispensable factors for TSERZ, and understanding the dynamic balance relationship of human-geology-ecology is the prerequisite and basis for TSERZ. Secondly, the proposed TSERZ framework emphasizes the fundamental role of carbon source/sink and lithology in TSERZ, constructing the three-level zones division method oriented towards carbon neutrality goal with the research line of “natural background conditions—dominant ecological functions—ecological stress problems”. Thirdly, the framework has been successfully applied to TSERZ in Yulong County, dividing it into 8 primary zones, 17 secondary zones, and 7 types key areas. Given its complex geological conditions, fragile ecological environment and increasingly human interference, Yulong County urgently needs to focus on restoring ecological problems such as rocky desertification and geological disasters to improve carbon sink capacity. This study innovatively constructs a cascading path for TSERZ from theoretical cognition to practical application, which can provide a reference for solving the TSERZ problem in geologically complex regions, especially in alpine-gorge regions.

The cognitive triad network - oscillation - behaviour links individual differences in EEG theta frequency with task performance and effective connectivity

We reconcile two significant lines of Cognitive Neuroscience research: the relationship between the structural and functional architecture of the brain and behaviour on the one hand and the functional significance of oscillatory brain processes to behavioural performance on the other. Network neuroscience proposes that the three elements, behavioural performance, EEG oscillation frequency, and network connectivity should be tightly connected at the individual level. Young and old healthy adults were recruited as a proxy for performance variation. An auditory inhibitory control task was used to demonstrate that task performance correlates with the individual EEG frontal theta frequency. Older adults had a significantly slower theta frequency, and both theta frequency and task performance correlated with the strengths of two network connections that involve the main areas of inhibitory control and speech processing. The results suggest that both the recruited functional network and the oscillation frequency induced by the task are specific to the task, are inseparable, and mark individual differences that directly link structure and function to behaviour in health and disease.

Solidaridad Intergeneracional y Salud Mental en Educación Superior: Programas Intergeneracionales

This study is a reflexive method practice that pretends to improve the teaching-learning processes through experience and the use of theory. This is how intergenerational programs based on solidarity and dialogue are approached as a support tool for a problem that is evident in the classrooms and that has an impact on the class dynamics, as well as on the academic student's achievement and their mental health. Day after day, significant problems such as depression, anxiety, and suicide in young students are increasing. Therefore, it is proposed a theorical and exploration approach by addressing the axes of reflective practice: professional scenario, personal experience, and reflection, visualizing the viability of intergenerational programs proposed by the authors approaching as critical- reflective prototypes from which there are undoubtedly several actions and lines of research to work, to achieve the validation and creation of this in the future. Taking as a case study the Autonomous University of Ciudad Juarez, where we seek to have a first approach to make a proposal related to intergenerational programs at higher education Institutions. With this theorical approach and multiple readings from international solidarity, dialogue, and existing programs from other parts of the world, the evidence allows us to think that this knowledge's proposal, development, and application enable the teachers to position themselves as an active agent of transformation and formation.

Rethinking IPE duration: a five-year comparative analysis of competency development across two introductory IPE course models

ABSTRACT Best practices have not yet been established in the interprofessional education (IPE) literature to guide the ideal dose and duration of IPE experiences across the curriculum. As such, the content, structure, and delivery format of IPE offerings vary significantly across institutions. The University of Minnesota had the rare opportunity to evaluate learner-perceived collaborative competency outcomes due to the transition of its centrally offered introductory IPE course. Data were collected consistently, longitudinally, and for a high volume of learners and professions across two IPE course models applied within the same academic institution. Retrospective analysis of pre-post interprofessional collaborative competency scores collected for over 5,000 learners from 17 health profession degree programs demonstrated nearly identical self-reported competency attainment for both a 12- and 4-hour introductory IPE offering, assessed using the ICCAS tool over the course of 5-year format transition. If student-reported competency attainment is the same following an introductory IPE experience regardless of the dosage, then academic IPE programs may be better positioned by decreasing their introductory emphasis and instead focus their resources on exploring innovative workplace-based and competency-based IPE strategies in line with contemporary recommendations. Further studies are needed to explore the implications of and next steps in this line of research.

Self-Reproduction and Evolution in Cellular Automata: 25 Years After Evoloops.

The year 2024 marks the 25th anniversary of the publication of evoloops, an evolutionary variant of Chris Langton's self-reproducing loops, which proved constructively that Darwinian evolution of self-reproducing organisms by variation and natural selection is possible within deterministic cellular automata. Over the last few decades, this line of Artificial Life research has since undergone several important developments. Although it experienced a relative dormancy of activity for a while, the recent rise of interest in open-ended evolution and the success of continuous cellular automata models have brought researchers' attention back to how to make spatiotemporal patterns self-reproduce and evolve within spatially distributed computational media. This article provides a review of the relevant literature on this topic over the past 25 years and highlights the major accomplishments made so far, the challenges being faced, and promising future research directions.

Thrombospondins: Conserved mediators and modulators of metazoan extracellular matrix.

This review provides a personal overview of significant scientific developments in the thrombospondin field during the course of my career. Thrombospondins are multidomain, multimeric, calcium-binding extracellular glycoproteins with context-specific roles in tissue organisation. They act at cell surfaces and within ECM to regulate cell phenotype and signalling, differentiation and assembly of collagenous ECM, along with tissue-specific roles in cartilage, angiogenesis and synaptic function. More recently, intracellular, homeostatic roles have also been identified. Resolution of structures for the major domains of mammalian thrombospondins has facilitated major advances in understanding thrombospondin biology from molecule to tissue; for example, in illuminating molecular consequences of disease-causing coding mutations in human pseudoachrondroplasia. Although principally studied in vertebrates, thrombospondins are amongst the most ancient of animal ECM proteins, with many invertebrates encoding a single thrombospondin and the thrombospondin gene family of vertebrates originating through gene duplications. Moreover, thrombospondins form one branch of a thrombospondin superfamily that debuted at the origin of metazoans. The super-family includes additional sub-groups, present only in invertebrates, that differ in N-terminal domain organisation, share the distinctive TSP C-terminal region domain architecture and, to the limited extent studied to date, apparently contribute to tissue development and organisation. Finally, major lines of translational research are discussed, related to fibrosis; TSP1, TSP2 and inhibition of angiogenesis; and the alleviation of chronic cartilage tissue pathologies in pseudoachrondroplasia.

An algebraic approach to the reconstruction of uniform hypergraphs from their degree sequence

The reconstruction of a (hyper)graph starting from its degree sequence is one of the most relevant among the inverse problems investigated in the field of graph theory. In case of graphs, a feasible solution can be quickly reached, while in case of hypergraphs Deza et al. (2018) proved that the problem is NP-hard even in the simple case of 3-uniform ones. This result opened a new research line consisting in the detection of instances for which a solution can be computed in polynomial time. In this work we deal with 3-uniform hypergraphs, and we study them from a different perspective, exploiting a connection of these objects with partially ordered sets. More precisely, we introduce a simple partially ordered set, whose ideals are in bijection with a subclass of 3-uniform hypergraphs. We completely characterize their degree sequences in case of principal ideals (here a simple fast reconstruction strategy follows), and we furthermore carry on a complete analysis of those degree sequences related to the ideals with two generators. We also consider unique hypergraphs in Dext, i.e., those hypergraphs that do not share their degree sequence with other non-isomorphic ones. We show that uniqueness holds in case of hypergraphs associated to principal ideals, and we provide some examples of hypergraphs in Dext where this property is lost.

Stem Cell Treatment for Dilated Cardiomyopathy: A Review of Recent Scientific Advances

Cardiomyopathy, a disorder of mechanical and electrical cardiac action, is a significant cause of morbidity and mortality in the United States and is seen in both adult and pediatric populations. Dilated cardiomyopathy, a subtype involving pathological enlargement of the heart, in particular causes significant reduction in quality of life and is a significant risk factor for heart failure development. Traditional treatment for dilated cardiomyopathy largely focuses on symptomatic relief and delayed progression of disease but does not offer a cure or reversal of disease process. In the past few decades, stem cell therapy has become a promising therapeutic because these cells can differentiate into human cardiomyocytes and offer a potential restoration of normal cardiomyocyte function. This review highlights 3 methodological derivations of cardiomyocytes: bone marrow–derived hematopoietic stem cells, mesenchymal stem cells, and adipose-derived stem cells. While most of the current research has focused on hematopoietic stem cells for dilated cardiomyopathy, further research is needed to elucidate which stem cell line is superior and most effective for disease treatment and reversal. This review highlights future directions of this line of research, such as direct comparison between cell types, analysis of the long-term effects of stem cell treatment, increased sample sizes, and potential use of this treatment in the pediatric and adult populations.

Experimental optimization and evaluation of an R600a/R1150 auto-cascade refrigeration systems for ultra-low temperature applications

Auto-cascade refrigeration systems are the most employed systems for ultra-low temperature applications, especially for small capacity systems. Recent investigations have allowed to analyze them energetically and thermodynamically, starting a research line focused on enhancing their energy performance from experimental approaches. This work focuses on the energy optimization of a real auto-cascade system working with the mixture R600a/R1150 [70/30 %], which has been evaluated using two compressor models for R404A and R290 as well as the optimization of the two capillary tubes used in the system. Results indicate that overall efficiency of the R290 compressor is up to 21 % higher than with R404A, leading to COP increments between 35 and 81 %. Optimum capillary lengths have been determined in terms of COP and energy consumption, reaching similar values, however, the inner parameters of the system change as function of these lengths, which needs to be considered in prototypes design.

Colonial Legacy and Informal Finance

An influential line of research emphasizes that colonial legacy plays a key role in formal financial development. Can colonial legacy also shape informal finance? We investigate the impact of colonial legacy on informal financial development using a manually georeferenced data set within a credible empirical framework. In the 19th century, Europeans arbitrarily designed colonial borders that partitioned many ethnicities across multiple countries in Africa. Leveraging several spatial regression discontinuity designs across national borders and within British-French–partitioned Cameroon and a unique natural experiment where the same former British colony is compared with two otherwise similar areas with different exposures to French colonization, we discover that former British colonies today have better informal financial development than former French colonies. Exploring the channels, we find that places with a British colonial legacy maintain a style of social control that facilitates information flow, supports private enforcement and market interactions, and promotes strong legal cultures.

A multispecies study reveals the diversity and potential regulatory role of long noncoding RNAs in cucurbits.

Plant long noncoding RNAs (lncRNAs) exhibit features such as tissue-specific expression, spatiotemporal regulation, and stress responsiveness. Although diverse studies support the regulatory role of lncRNAs in model plants, our knowledge about lncRNAs in crops is limited. We employ a custom pipeline on a dataset of over 1000 RNA-seq samples across nine representative species of the family Cucurbitaceae to predict 91 209 nonredundant lncRNAs. The lncRNAs were characterized according to three confidence levels and classified by their genomic context into intergenic, natural antisense, intronic, and sense-overlapping. Compared with protein-coding genes, lncRNAs were, on average, expressed at low levels and displayed significantly higher specificity when considering tissue, developmental stages, and stress responsiveness. The evolutionary analysis indicates higher positional conservation than sequence conservation, probably linked to the conserved modular motifs within syntenic lncRNAs. Moreover, a positive correlation between the expression of intergenic/natural antisense lncRNAs and their closest/parental gene was observed. For those intergenic, the correlation decreases with the distance to the neighboring gene, supporting that their potential cis-regulatory effect is within a short-range. Furthermore, the analysis of developmental studies showed that a conserved NAT-lncRNA family is differentially expressed in a coordinated way with their cognate sense protein-coding genes. These genes code for proteins associated with phloem development, thus providing insights about the potential involvement of some of the identified lncRNAs in a developmental process. We expect that this extensive inventory will constitute a valuable resource for further research lines focused on elucidating the regulatory mechanisms mediated by lncRNAs in cucurbits.

Development and validation of a realistic type III esophageal atresia simulator for the training of pediatric surgeons

BackgroundThe technical complexity and limited casuistry of neonatal surgical pathology limit the possibilities of developing the necessary technical competencies by specialists in training. Esophageal atresia constitutes the paradigm of this problem. The use of synthetic 3D models for training is a promising line of research, although the literature is limited.MethodsWe conceptualized, designed, and produced an anatomically realistic model for the open correction of type III oesophageal atresia. We validated it with two groups of participants (experts and non-experts) through face, construct, and content-validity questionnaires.ResultsThe model was validated by nine experts and nine non-experts. The mean procedure time for the experts and non-experts groups was 34.0 and 38.4 min, respectively. Two non-experts did not complete the procedure at the designed time (45 min). Regarding the face validity questionnaire, the mean rating of the model was 3.2 out of 4. Regarding the construct validity, we found statistically significant differences between groups for the equidistance between sutures, 100% correct in the expert group vs. 42.9% correct in the non-expert group (p = 0.02), and for the item “Confirms that tracheoesophageal fistula closure is watertight before continuing the procedure”, correctly assessed by 66.7% of the experts vs. by 11.1% of non-experts (p = 0.05). Concerning content validity, the mean score was 3.3 out of 4 for the experts and 3.4 out of 4 for the non-experts.ConclusionsThe present model is a cost-effective, simple-to-produce, and validated option for training open correction of type III esophageal atresia. However, future studies with larger sample sizes and blinded validators are needed before drawing definitive conclusions.

Another Evidence to not Employ Customized Masked Hardware

As a well-studied countermeasure against side-channel analysis attacks, there is a general interest in applying masking to different cryptographic functions executed on different platforms. On the one hand, despite their high performance, masked hardware implementations are dedicated to specific algorithms, making them inflexible. On the other hand, applying masking on software involves serious challenges including significant overhead in terms of efficiency and difficulties to maintain theoretical security guarantees in practice. As a result, a line of research has been devoted to enable masked operations in flexible platforms (i.e., microprocessors) by including some masked modules in their hardware, hence a combination of flexibility and performance. In such scenarios, RISC-V is a natural choice as hardware can be adjusted to the extended instruction set. One such attempt presented at CHES 2021 is known as SCARV, which extends the Instruction Set Architecture (ISA) of a RISC-V core with a rich number of first-order masked operations on both Boolean and arithmetic masked operands. In this work, we conduct a comprehensive analysis of SCARV. Instead of relying on empirical measurements to demonstrate security, we utilize tool-assisted evaluations. Through these evaluations, we identified a couple of design flaws that lead to leakage in the masked implementations hosted by the corresponding processor. These flaws are primarily due to the lack of composability of cascaded components. While heuristic and ad-hoc design principles can result in secure, small, and efficient designs, they lack formal security proofs, which may lead to security flaws, like those we report here. Consequently, this work serves as a motivation for using composable masked modules and tool-assisted evaluations when constructing complex circuits.
