This paper introduces apanel on temporality in the work of Hans Loewald, presented at an IARPP conference in 2022. The presenters highlight Loewald's idea that the experience of time shapes our understanding of ourselves and the world. Each author applies Loewald's notion of temporality to clinical material: Cheryl Goldstein uses the image of a"rift" in our relationship to time in her treatment of ayoung woman unable to bear the guilt of separating from adepressive mother. Shoulamit Milch Reich and Amir Atsmon present the case of atraumatized young boy unable to integrate, or link, the dimensions of past, present, and future, resulting in fragmentation and psychic collapse. Robin Young and Gila Ofer each explore gender development through aLoewaldian lens in which regressive wishes can safely emerge in treatment and ego development resume. Implicit in these presentations is the seminal influence of Loewald on clinical work and his integrative appeal across psychoanalytic orientations. [ABSTRACT FROM AUTHOR]

Global demand for animal protein is on the rise, but many practices common in conventional production are no longer scalable due to environmental impact, public health concerns, and fragility of food systems. For these reasons and more, a pressing need has arisen for sustainable, nutritious, and animal welfare–conscious sources of protein, spurring research dedicated to the production of cultivated meat. Meat mainly consists of muscle, fat, and connective tissue, all of which can be sourced and differentiated from pluripotent stem cells to resemble their nutritional values in muscle tissue. In this paper, we outline the approach that we took to derive bovine embryonic stem cell lines (bESCs) and to characterise them using FACS (fluorescence-activated cell sorting), real-time PCR and immunofluorescence staining. We show their cell growth profile and genetic stability and demonstrate their induced differentiation to mesoderm committed cells. In addition, we discuss our strategy for preparation of master and working cell banks, by which we can expand and grow cells in suspension in quantities suitable for mass production. Consequently, we demonstrate the potential benefits of harnessing bESCs in the production of cultivated meat. Global demand for sustainable, nutritious, and animal welfare–conscious protein sources encourages research dedicated to the production of cultivated meat. In this paper, we outline the approach that we took to produce bovine embryonic stem cell lines and present our strategy to expand and grow cells in quantities suitable for mass production. Our work demonstrates the potential benefits of harnessing bESCs in the production of cultivated meat. Photograph by Dr. Irena Vertkin (researcher, R&D department, Aleph Farms).

Differentiation in education can be seen as a means of responding to student diversity in order to meet the vision of a school for all. Differentiation has been widely addressed within a western context, and it appears to be a versatile phenomenon as it occurs under various guises and with a variety of terms and modes of operationalizations. The aim of this configurative review is to investigate how differentiation appears in the international context and to contribute to a much-needed overview of the concept. Analysis of 28 scientific papers representing a broad range of national affiliations resulted in two main findings. First, differentiation is a complex idea that appears to be presented either as differentiating students or differentiating teaching. Four perspectives for approaching differentiation further illustrate the complexity of the phenomenon: differentiation as individualization, differentiation as adaptation to specific groups, differentiation as adaptations within diverse classrooms, and differentiation in a system perspective. Second, the analysis revealed that there are almost no studies transcending the focus on teachers and the classroom by addressing the organizational or system/policy level. This review argues for the benefits that a more system-oriented perspective of differentiation would provide. [ABSTRACT FROM AUTHOR]

In the field of international business, examination of the link between a market orientation (MO) and an export performance (EP) is quite popular. However, mechanisms through which MO affects EP have not been sufficiently investigated. The aim of this paper was to examine direct and indirect impact of MO on EP, as well as drivers of MO. In this paper, MO is defined as organisational culture. Based on the structure-conduct-performance paradigm and Resource-Based View, a model was formulated and tested on a sample of 121 large and medium-sized exporters operating in the Republic of Serbia. The method applied was partial least squares structural equation modelling (PLS-SEM). Obtained results indicate that there is a direct and positive effect of relational resources and competitive intensity on MO. It was also found that MO affects EP directly, and that differentiation strategy partially mediates the relationship between MO and EP. [ABSTRACT FROM AUTHOR]

The literature about the asymptotic numerical method (ANM) is reviewed in this paper as well as its application to hyperelasticity and elastoplasticity. ANM is a generic continuation method based on the computation of Taylor series for solving nonlinear partial differential equations. Modern techniques of high-order differentiation provide simple tools for computing these power series, the corresponding algorithms for finite strain elasticity and elastoplasticity being summarized here. Taylor series is not only a computation tool, but it contains also useful information about the structure of the considered solution curve. The paper ends with a short historical account about the development of this numerical method. [ABSTRACT FROM AUTHOR]

Reinforcement, extinction, generalization and differentiation are all basic principles of Pavlov associative memory. Most memristive neural networks that simulate associative memory only consider reinforcement and extinction, while ignoring differentiation and generalization. In this paper, a memristive circuit of associative memory with generalization and differentiation is proposed to solve the above problem. It implements the functions of learning, forgetting, long-term memory, generalization and differentiation. Learning and forgetting correspond to reinforcement and extinction in associative memory respectively. Spontaneous recovery, in which forgotten reflexes can reappear in the absence of an unconditional stimulus, is also discussed here. Besides, a special differentiation method that takes into account the time delay is designed and demonstrated. The proposed memristive circuit of associative memory provides a reference for the theoretical research and application of artificial neural networks. [ABSTRACT FROM AUTHOR]

Neuroblastoma is a type of peripheral neuroblastic tumor and is a common malignant solid tumor in children with significant biological heterogeneity and rapid development. Determining the type of differentiation is important in predicting the prognosis of neuroblastoma and making early judgments on postoperative treatment plans. The whole slide images of neuroblastoma offer high resolution that greatly facilitates clinical reading. However, the high resolution of these images makes computer-aided diagnosis quite challenging. To address the challenge, we propose in this paper a network model based on the traditional encoder-decoder structure of U-Net. The model uses DenseNet as the encoder to extract features of image, initializes network weights by transfer learning, and builds the decoder based on the up-sampling module and dense block to extract different types of cells. K-means algorithm is used to cluster and count the poorly differentiated cells and differentiated cells, identifying the histopathological types and the prognostic effects. Our experimental results demonstrate that our model performs excellently, having achieved 97.55% of segmentation accuracy, 92.10% and 89.02% counting accuracy for poor differentiated cells and differentiated cells, respectively.

This article describes Dr. Murray Bowen's original research from which the concept of differentiation of self emerged. Bowen's extension of the concept ultimately developed into the science of human behavior now known as Bowen theory. The descriptions here are taken from materials in the Bowen archives at the National Library of Medicine and from the Bowen family materials in Williamsburg, Virginia. Late in his life, when Bowen was drafting his 1988 epilogue "An Odyssey Toward Science" for the book Family Evaluation, he did a thorough review of the earliest periods of the development of his theory. These notes, along with his papers going back fifty years, are now in the archival collection at the National Library of Medicine. Bowen's review, coupled with the actual works from that time, offers a solid opportunity to document his path toward a theory that would extend Freudian theory to integrate more closely with breakthroughs in other sciences. While he maintained a respect for Freud's efforts, when the data supported an alternative theory, Bowen went with the data. This article describes this process, especially with regard to the origin of his concept of differentiation of self, and illuminates the value of the Bowen archives for understanding how the theory originated.

In recent years, spatial transcriptomics (ST) research has become a popular field of study and has shown great potential in medicine. However, there are few bibliometric analyses in this field. Thus, in this study, we aimed to find and analyze the frontiers and trends of this medical research field based on the available literature. A computerized search was applied to the WoSCC (Web of Science Core Collection) Database for literature published from 2006 to 2023. Complete records of all literature and cited references were extracted and screened. The bibliometric analysis and visualization were performed using CiteSpace, VOSviewer, Bibliometrix R Package software, and Scimago Graphica. A total of 1467 papers and reviews were included. The analysis revealed that the ST publication and citation results have shown a rapid upward trend over the last 3 years. Nature Communications and Nature were the most productive and most co-cited journals, respectively. In the comprehensive global collaborative network, the United States is the country with the most organizations and publications, followed closely by China and the United Kingdom. The author Joakim Lundeberg published the most cited paper, while Patrik L. Ståhl ranked first among co-cited authors. The hot topics in ST are tissue recognition, cancer, heterogeneity, immunotherapy, differentiation, and models. ST technologies have greatly contributed to in-depth research in medical fields such as oncology and neuroscience, opening up new possibilities for the diagnosis and treatment of diseases. Moreover, artificial intelligence and big data drive additional development in ST fields. Spatial transcriptomics (ST) technologies and application prospects. (1) Imaging-based approaches, including in situ sequencing (ISS)—where transcripts are amplified and sequenced in tissue—and ISH-based approaches—where imaging probes are sequentially hybridized in tissue. (2) NGS-based techniques, in which positional information is encoded onto transcripts prior to NGS sequencing. [ABSTRACT FROM AUTHOR]

Among the theoretical contributions made by Hans Loewald, some of the most meaningful address the developmental process of differentiation from a primary or original unity into "id-ego and objects." This differentiation requires "separation, loss, and restitution," and results in a shift from oneness/unity to at-onement, a connection that bears within it the trace of the separation it emends. A parallel dynamic plays out in the shift from identification to internalization in Loewald's work. The author identifies this dynamic as cohering difference, a structural interaction in both intra- and inter-psychic processes graphically illustrated by the hyphen in Loewald's concept of "at-onement." The author examines these processes and the significance of cohering difference, illustrated by Loewald's idea of "linking," and presents a clinical example in which loss, grief, identification, and internalization play key roles.

The division of the world into 'developing' and 'developed' countries has grown increasingly problematic in the past decades. Nonetheless, it remains embedded in legal documents, foreign policy discourse, and colloquial use. This paper explores this complexity by unpacking the different ways in which the 'developing' label is used in the international system. It argues that understanding the complexity around its use requires a rigorous analysis of the label's diverse meanings and consequences. This is done by introducing a taxonomy that intersects two elements: (1) the source of the classification (External or Internal) and (2) the kind of hierarchy implied in the classification (Narrow or Broad). This two-by-two matrix generates four approaches in which the 'developing' vs 'developed' dichotomy is used: Technocratic, Elective, Northern Gaze, and Southern Solidarity. Each approach is explored empirically, illustrated by cases connected to international organizations and multilateral treaties. In doing so, the paper teases out the underlying reasons why the use of the dichotomy is so challenging, based on what kinds of contestation it generates, and which actors are pushing for demise or longevity (and where).

This paper introduces the concept of decompression as a specific process of differentiation. Decompression can be anchored as one of the phenomena of non-compliance, representing a distinctive phenomenon, however. Governments or leaders acting in a decompression way are not Eurosceptics and they do not want to reverse the course of integration. We define decompression as a sudden violation of an EU rule by a member state, which leads to immediate disruption of shared trust in a basic EU policy or principle. In the case of a crisis, we can see a 'compression', an unexpected crisis-driven demand placed on domestic institutions. Decompression is a relaxation of this pressure triggering the non-application of an EU policy or principle in reaction to changes external to the political equilibrium. It sheds new light on the persistent power of individual politicians to compromise European integration in an unintended way, so far under-reported by the literature. [ABSTRACT FROM AUTHOR]

Purpose: To (a) present a theoretical framework that describes how learners' movement habits become relevant in the development of movement capability and (b) present data that illustrate how this process occurs in practice. Method: An investigation with preservice physical education teachers was conducted in two phases. The first phase involved examining participants' movement habits, and the second phase involved examining the participants' development of novel capabilities in the context of unicycling. Results: Empirical materials from two participants are presented as case studies. The cases demonstrate how different sets of movement habits interact with novel tasks, making the demand for creative action more or less likely. The cases also demonstrate how subjective and physical elements are interwoven. Finally, the cases provide insights into potentially productive habits for movement learning. Discussion/Conclusion: The paper is concluded with pedagogical implications, including a consideration of how crises might be managed in educational contexts. [ABSTRACT FROM AUTHOR]

Previous literature informed by biopolitical theory has shown how global education for sustainable development differentiates between populations by assigning different roles, responsibilities, and lifestyles to rich and poor. Taking these arguments as a point of departure, this paper first identifies three different 'problems' pertaining to biopolitical differentiation within this literature and then elaborates on potential didactical responses to such problematic differentiation. The suggested didactical responses draw on Judith Butler's theories of vulnerability, Jacques Rancière's ideas of a presupposition of equality, and Michel Foucault's writing on ethics and self-formation. The paper contributes to previous research on biopolitical differentiation in education for sustainable development by suggesting potential didactical responses to the problematics put forth in these works. It also contributes to previous literature on how Butler's, Rancière's and Foucault's theories are relevant to education by relocating the arguments to the context of global implementation of education for sustainable development.

Much has been said about how crises in the EU create disintegration or differentiation pressures. Considerable attention has been paid to EU crisis governance mechanisms. Yet, less attention has been paid to the anticipation of effects of differentiated implementation on transboundary crisis management regimes. This article asks how differential policy integration accommodates the anticipation of differential implementation through institutional choices in transboundary crisis management regimes. Concerns about the consequences of national customisation influence the way in which transboundary crisis management regimes develop in terms of allocation of authority and constraints on member state discretion. The paper compares EU transboundary crisis regimes in four sectors: banking, electricity, youth unemployment, and invasive alien species. Concerns with ongoing differential implementation of transboundary crisis management generate further inevitable tensions in governance systems, leading to continued contestation over institutional arrangements.

In this paper, we develop a theoretical framework that explains how digital technologies can help small businesses generate competitive advantages for scaling. To gain and sustain competitive advantages, small businesses traditionally had to choose between cost leadership and differentiation strategies. Digital technologies enable small businesses to reduce their costs and at the same time enhance the value of their market offerings through differentiation. The aim of this paper is to explain the role of digital technologies in such hybrid strategies for small businesses. We first identify automation, individualization and interdisciplinarity as the three dimensions of digital technologies that together enable technology-driven firms to gain and sustain competitive advantages and to scale rapidly. Second, we integrate these three dimensions into a theoretical framework. Third, we test and confirm the theoretical framework in an explanatory case study and discuss the results.

The aim of this paper is to validate a multidimensional measurement of design orientation and test its links with marketing design integration and competitive advantage in trade and tourism companies. Structural equations modelling was used to analyse data from 421 service firms. The results show that design orientation helps firms to achieve a competitive advantage and thus improve their relationship with service users and their business effectiveness. This study provides trade and tourism firms with an instrument to accomplish design orientation by assessing its constituent dimensions. [ABSTRACT FROM AUTHOR]

School district administrators must address structural racism and inequitable access to advanced learning opportunities in their school districts. District administrators in one large district in the northwestern part of the United States sought research-based advice by asking the authors to provide the answer to the "million-dollar" question, " What is the most effective and equitable way to deliver services to advanced learners? " This paper shares the response provided to the school district and discusses the complexity of the question. Based on a systematic literature review of best practices in the field of gifted education, we share our findings in three categories: (1) administrative structures, (2) pedagogy of gifted education, and (3) social and emotional considerations for advanced learners. We conclude by offering recommendations drawn from this review to develop a holistic view of programming and serving all students with advanced academic needs. [ABSTRACT FROM AUTHOR]

Equalizing opportunities for students to learn science and engineering in the ways described in the Next Generation Science Standards (NGSS) requires intentional planning. In this paper, we describe a framework for designing equitable and inclusive science lessons. We then share an example of how this framework was applied to the launch of a fifth-grade science unit, specifying the instructional strategies used to provide students with a meaningful, relevant, and engaging learning experience.

The Standard Gauge Railway (SGR) in Kenya, inaugurated in 2017, has been promoted by the Kenyan government as a promise of "development" and "prospering people." This paper demonstrates how, contrary to these narratives, the SGR reiterates the pre‐existing relations of difference mediated by class, geography, and ethnicity. Focusing on material and semiotic forms of the SGR infrastructures, it specifically shows how the railway project functions as the techno‐politics of differentiation that governs by including "prospering publics" of urban middle classes into Kenya's modernist development vision, providing unstable hopes for "development" to more precarious peri‐urban and rural "anticipating populations," but simultaneously constituting "excluded populations" in rural landscapes that are denied the possibility of being a part of the national modernist development vision. Highlighting this intimate relationship between infrastructure, governance, and biopolitics, the paper demonstrates that mega‐infrastructures – differentiating between the publics included in, and the populations excluded from, the state's development visions and practices, as well as unstable subjective dispositions in‐between – engender modalities of non‐belonging that fall outside of (inherently liberal) frames of "citizenship" or a "public" frequently employed in critical infrastructure scholarship.

This paper explores the relationship between the illicit opium economy and processes of agrarian change in south‐western Shan State, Myanmar. This is a region where opium production has risen significantly since the 1990s despite the declining territorial control of insurgent groups long blamed for the country's illegal drug economy and alongside the deepening integration of the region's agriculture sector into national and global markets. This paper reveals how illicit opium cultivation has offered distressed smallholders a way to mitigate the worsening livelihood insecurities that have accompanied the commercialization of smallholder agriculture. Yet at the same time, opium cultivation has locked farmers into a set of highly unequal social relations that has enabled militias, businesspeople with ties to local (armed) authorities, moneylenders, and agricultural brokers to accumulate capital through their control over rural markets and credit systems while leaving poppy cultivators with little more than the means to reproduce their livelihoods. This paper thus shows how opium cultivation has enabled farmers to respond to worsening precarity by sustaining smallholder farming despite the worsening "reproduction squeeze" facing many households, although the opium economy has simultaneously played an instrumental role in reinforcing and deepening agrarian class relations.

A companion paper in this issue of Surface and Interface Analysis (Surf Interface Anal. 2021;1–6. doi: 10.1002/sia.7029) discusses corrections for the effects of analyzer modulation on peak intensity in derivative Auger spectra. Today, most Auger spectra are acquired in the direct mode, E·N(E), and derivatives are taken using a computer program to measure peak intensities (peak‐to‐peak heights) with the background suppressed, for ultimate quantification. In taking a derivative, there is sometimes a choice of the algorithm used for taking the derivative, but the most common method is to use the Savitzky–Golay algorithm. In using the Savitzky–Golay algorithm, there is also a choice in the number of data points used in the differentiation. To improve quantification, Martin Seah suggested using relatively large Gaussian broadening in the differentiation process to reduced effects of line shape differences in measuring signal intensities, as often occur due to chemical effects on spectra. This paper shows the effects of the number of points used with the Savitzky–Golay algorithm in taking the derivative on peak‐to‐peak heights in derivative Auger spectra and how dynamic background subtraction can be used to obtain Auger peak area values independent of the broadening of spectra caused by such differentiation.

Simple Summary: Cell therapy is emerging as a promising modality to treat cancers such as hematological malignancies and solid tumors; hence there is a need to develop processes to manufacture and maintain functional and lasting cells. The use of cytokines, as well as transcription and growth factors, is critical to ensure effective cell therapeutics. This is especially important for allogeneic cell therapies that employ induced pluripotent stem cells (iPSC). The use of iPSC offers the potential to treat a large number of patients with consistent material without relying on limited donor cells and the delay associated with processing immediately before treatment. This paper demonstrates the importance and use of cytokines and growth factors in driving the iPSC-to-effector differentiation and expansion process, which leads to the generation of functional and persistent immune-effector cells such as natural killer cells or T cells. Cytokines and other growth factors are essential for cell expansion, health, function, and immune stimulation. Stem cells have the additional reliance on these factors to direct differentiation to the appropriate terminal cell type. Successful manufacturing of allogeneic cell therapies from induced pluripotent stem cells (iPSCs) requires close attention to the selection and control of cytokines and factors used throughout the manufacturing process, as well as after administration to the patient. This paper employs iPSC-derived natural killer cell/T cell therapeutics to illustrate the use of cytokines, growth factors, and transcription factors at different stages of the manufacturing process, ranging from the generation of iPSCs to controlling of iPSC differentiation into immune-effector cells through the support of cell therapy after patient administration.

Differentiation is a foundational premise in the study of middle powers, as evident in the way that the relevant literature distinguishes these states from the great powers and smaller states. Despite the underlying assumption of differentiation, the middle power literature has rarely engaged theoretically with the concept. This paper seeks to make more explicit this basis of differentiation in the study of middle powers, by advancing a new framework for middle power behavior that draws on differentiation theory. The framework makes the case that it is the differentiated structure in international politics – a departure from the dominant neorealist understanding of structure – that enables the behavior of middle powers. The effects of this differentiated structure are activated by the relative, relational, and social power politics that middle powers engage in, in a particular time and place. Through this process, middle powers are able to leverage their 'middlepowerness' in international politics by weakening stratification particularly where the great powers are concerned, and strengthening functional differentiation through taking on key and distinctive roles. By putting differentiation at the core of a framework for middle power behavior, the paper strives to make a constructive contribution to the theorizing of middle powers. [ABSTRACT FROM AUTHOR]

Recently, the new global policy framework for implementing education for sustainable development (ESD) – ESD for 2030 – was launched officially. Drawing on Foucauldian theory, this paper explores biopolitical elements in ESD for 2030. The paper contributes to previous research on ESD policy by employing a biopolitical perspective, and by highlighting problematic aspects of the framework's will to include and to adapt to different contexts. The analysis brings attention to the framework's notions of life and to how different human populations are separated. Furthermore, the analysis of the framework demonstrates how notions of transformative pedagogy, community, and the individual, assume the functions of biopolitical techniques. The findings point to a biopolitical differentiation where rich and poor populations are assumed to need different educational interventions, adapted to their socio-economic contexts, in the global educational policy quest for sustainable development. Ultimately, we consider the potential of Foucauldian ethics as an affirmative alternative to the current mode of biopolitical differentiation in global ESD policy [ABSTRACT FROM AUTHOR]

The provision of inclusive learning materials has been a longstanding issue in FL education. During the 2020 pandemic, school closures have posed additional challenges to educators seeking to engage learners and provide egalitarian access to learning opportunities. This case study documents a collaborative materials design process when the COVID-19 pandemic forced Chilean schools into remote lessons for a whole school year. The collaboration was based on a small professional learning network consisting of two pre-service teachers and two teacher educators. Two questions were posed: What learning and circumstantial needs had to be considered for materials design and for the process of making the materials accessible to a diverse group of Year-9 EFL learners? What were the benefits and challenges for this networked learning system when searching for solutions? Findings: The combination of different access modes to materials, including paper-based worksheets and social networking, and the provision of internet access to facilitate video conferences, helped to overcome some but not all of the limitations caused by the lack of political commitment to offer solutions at a macro level. Based on a framework that combined principles of Differentiated Instruction, Universal Design for Learning, multimodality and bilingual support, the team developed materials at an appropriate level for most students. However, difficulties regarding differentiation between different learner levels persisted. This study sheds light on the affordances and challenges of a collaborative materials design process in which educators join perspectives to provide materials for greater educational justice in FL classrooms.

The genesis of the education system is linked with the rapid expansion of school education in the eighteenth and nineteenth century. The genesis of the education system therefore brought about a primary form of differentiation in the education system, viz. the differentiation between family and school. Family education and school education can be seen as differentiated units of a more encompassing unit. This paper explores changes in the relationship between these subsystems with the help of systems theory. We particularly discuss tensions between families and schools that have emerged in recent decades as a consequence of the growing societal impact and status of formal schooling. Highlighting the heterogeneity that exists within the education system, we argue that loose coupling, instead of strict coupling, may have major advantages for the primary subsystems of the education system. In the concluding section, we call for more careful reflections within the education system on the pressures and tensions between its primary subsystems. [ABSTRACT FROM AUTHOR]
