Additive manufacturing of copper parts using extrusion and sinter-based technology: evaluation of the influence of printing parameters and debinding method
Authors: Pellegrini Alessandro , Lavecchia Fulvio , Guerra Maria Grazia 
Published: July 2024

Purpose
This work is focused on the realization of copper parts using the material extrusion additive manufacturing debinding and sintering (MEX+D&S) technology.

Design/methodology/approach
A highly filled filament with 90 Wt.% of copper is used to realize nine different combinations varying the printing speed and the flow rate. The following thermal debinding and sintering are performed at 483 °C and 1057 °C, respectively, burying the samples in specific refractory powder and carbon. The green and sintered density are measured and an inspection at optical microscope is implemented for a detailed internal analysis of the defects.

Findings
The samples, that reported the highest values of the green density, become the worst in the sintered condition due to evident swelling defect generated by the entrapped polymer during the thermal debinding. On the other hand, the parts with the lower values of green density allowed to achieve a satisfying density value without significant external defects.

Originality/value
The realization of copper parts through laser-based additive manufacturing technologies shows several troubles related to the rapid heat transfer and the high reflectivity of copper, which is a hinder of the absorption of the laser power. The MEX+D&S becomes an easier and economical alternative for the realization of copper parts. The internal inspection of the samples revealed the need for the improvement on the process chain, adopting a different debinding process to open channels during the thermal debinding to avoid the entrapment of the polymer.

Published: July 2024

Purpose
This study aims to bridge a gap in literature by exploring the impact of art and culture projects on primary internal stakeholders (i.e. employees), focusing on the micro-foundations of corporate social responsibility (CSR).

Design/methodology/approach
The analysis uses a qualitative approach, using a single-case study and semi-structured interviews. The single-case study focuses on art and culture projects developed by companies participating in the public contest promoted by Parma City of Culture 2020. The analysis relies on the information gathered from interviews with the employees who were involved in the projects of seven of the winning companies.

Findings
The results suggest that employees positively assess their participation in CSR activities based on art and culture projects. Specifically, through their direct involvement in the competition employees manage to experience meaningfulness and they attribute intrinsic motives to these types of activities.

Originality/value
This study analyses the effectiveness of a publicly endorsed CSR initiative oriented towards internal social enhancement based on art and culture projects, leveraging the unique case of Parma City of Culture 2020. The findings might be beneficial to both companies and regulators aiming to achieve internal social enhancement. This study contributes to existing literature on the social dimension of CSR by emphasising the key role of art and culture projects in the organisational context and by opening new avenues for future research.

Published: July 2024

Purpose
This study aims to examine the relationship between corporate social responsibility (CSR) and job pursuit intention (JPI), and the role of job seekers’ perception on employer prosocial orientation, value congruence and employer attractiveness in this relationship. CSR is measured based on internal and external CSR.

Design/methodology/approach
By adopting quantitative approach, data was obtained through survey questionnaire from 420 bachelor’s degree university fresh graduates from five universities in Malaysia who are actively seeking for jobs. Data was analysed using structural equation modelling technique.

Findings
Research findings show that internal and external CSR positively impact job seekers’ perception of employer prosocial orientation. Job seekers’ perception towards employer prosocial orientation has a significant positive impact on value congruence. Value congruence has a significant positive influence on employer attractiveness. Finally, employer attractiveness has a significant positive impact on JPI.

Practical implications
The findings are useful for human resources management. Organisations (employers) should focus on effective internal and external CSR practices through a prosocial orientation approach to attract the best talents and create a strong position in the job market.

Originality/value
This study extends the Signalling Theory and P-O Fit theory by applying them to an entirely different context of CSR and JPI, by incorporated the holistic job seekers’ psychological processes of the recruitment signals (internal and external CSR), signalling process and person-organisation fit (perception on employer prosocial orientation, value congruence and employer attractiveness) thoroughly.

Published: July 2024

AbstractMarine magnetometry very close to the targeted sources, even in very deep waters, is today a reality with the advent of autonomous underwater vehicles. We argue that a successful approach is to fully integrate the magnetometer onboard the autonomous underwater vehicle and to deal with its static magnetic noise, that is induced and permanent fields of the drone, with a 3‐axis vector measurement of the Earth's magnetic field. This argument is supported by results from three magnetic surveys performed with different fluxgate magnetic sensors embedded in autonomous underwater vehicles of increasing sizes. They show that simple specifically defined figures of merit coupled to an optimized scalar calibration procedure derived from aeromagnetic and satellite‐borne developments produce reliable magnetic measurements from autonomous underwater vehicles for geophysical mapping or detection applications. Results are impressive and show that even weak magnetic anomalies smaller than 10 nT can be highlighted even though the magnetic signatures of autonomous underwater vehicles can be orders of magnitude higher.
Children picturing their own worlds: Using photovoice to amplify children’s voice in sociological research
Authors: Ferraro A. C. , Maher Erin J. 
Published: July 2024

AbstractThis research note highlights an emerging transdisciplinary research method—photovoice—and why it is particularly suited for sociological studies of children and youth. Traditional social science data collection methods can be limited in their ability to capture both the depth and breadth of childhood experiences and children's perceptions of their experiences. We describe an emerging method, photovoice, that is used more frequently in other disciplines, and its suitability for sociologically studying youth and children. We describe the limitations of traditional social science methods and how photovoice can help overcome some of these limitations. Photovoice engages participants as lived experts who contribute to both the data collection and analysis in an individual and collective manner. Through taking photos and discussing their meaning, participants can share abstract feelings and discuss sensitive topics in an imaginative format and express themselves creatively. We describe how previous research has used photovoice to work with youth from vulnerable circumstances and those who have experienced trauma as well as demonstrate how photovoice is well situated to bolster the tenets of sociological research.

SummaryPeptide‐binding motif (PBM) model, a hierarchical clustering of HLA class I based on their binding specificity, was developed to predict immunopeptidome divergence. The effect of PBM mismatches on outcomes is unknown in HLA‐haploidentical haematopoietic cell transplantation with post‐transplant cyclophosphamide (PTCy‐haplo). We therefore conducted a retrospective study using national registry data in PTCy‐haplo. Overall, 1352 patients were included in the study. PBM‐A bidirectional mismatch was associated with an increased risk of overall mortality in multivariable analysis (hazard ratio, 1.26; 95% confidence interval, 1.06 to 1.50; p = 0.010). None of relapse, non‐relapse mortality (NRM) and graft‐versus‐host disease showed significant differences according to PBM‐A bidirectional mismatch status in the entire cohort. The impact of PBM‐A bidirectional mismatch on overall survival (OS) was preserved within the HLA‐A genotype bidirectional mismatch population, and their lower OS stemmed from higher relapse rate in this population. The worse OS due to high NRM with PBM‐A bidirectional mismatch was prominent in lymphoid malignancies receiving reduced‐intensity conditioning. The PBM model may predict outcomes more accurately than HLA genotype mismatches. In conclusion, this study demonstrated that the presence of PBM‐A bidirectional mismatch elevated the risk of mortality of PTCy‐haplo. Avoiding PBM‐A bidirectional mismatch might achieve better outcomes in PTCy‐haplo.

Emerging Ideas. Family estrangement and its association with life satisfaction and depressiveness in adulthood
Authors: Hank Karsten 
Published: July 2024

AbstractObjectiveThe aim was (a) to assess the association between family estrangement and psychological well‐being in adulthood, (b) to investigate potential differences in this association by type of relationship (intergenerational vs. siblings), and (c) to assess whether estrangement from multiple family relations (parents and siblings) is associated with cumulative disadvantage.BackgroundFamily estrangement is a quantitatively relevant phenomenon, whose association with psychological well‐being in adulthood has been insufficiently investigated.MethodAnalysis of data from the German Family Panel (pairfam; N = 5,245) involved running ordinary least squares regressions on the association between previous experiences of family estrangement (in Waves 5, 7, 9, and 11) with respondents' (aged 24–48 years) life satisfaction and depressiveness in Wave 11.ResultsFamily estrangement was negatively correlated with psychological well‐being. The strength of this relationship did not substantially differ by type of relationship (parents vs. siblings). Associations were strongest if estrangement from both parental and sibling ties was reported.ConclusionFamily estrangement is significantly associated with reduced psychological well‐being. This applies to vertical and horizontal ties in the family system. Co‐occurrence of estrangement from parents and siblings bears particularly strong negative relationships with psychological well‐being.ImplicationsResearchers and practitioners should consider spillovers of estrangement processes among family members and be aware of cumulative disadvantages this might bring about.
Eggs on a plate: Population‐dependent effects of humic substance rich water on perch egg size and hatching success

Abstract

The ability of fish to sustain environmental perturbations during fragile early‐life stages can be of vital importance for populations and species facing rapid global environmental change. One of the potential challenges for aquatic organisms, including teleost fish, is rising concentration of dissolved organic carbon (DOC) in freshwater environments, known as brownification, which causes a cascade of changes including a decreased visibility and pH. Conversely, humic substances are increasingly recognised for their potential antimicrobial and immunostimulant properties. The questions remain whether exposure to humic waters high in DOC during the development causes significant perturbation, and to what extent genetic and parental factors may maintain optimal development in such a possibly challenging environment.

To address these questions, we generated pure and hybrid (inter‐population) crosses of Eurasian perch (Perca fluviatilis) originating from clear‐water and humic lakes. Fertilised eggs from each cross were exposed to natural humic and clear‐water lake water. Intra‐chorionic space diameter (embryo diameter) and hatching success were recorded.

Perch embryos successfully developed even in a small volume of water (5 mL) and majority hatched (70%) by 13 day post‐fertilisation. Embryo diameter was influenced by the interaction between cross type and treatment where embryos with maternal clear‐water origin were smaller than embryos of humic water origin in both clear‐water and humic water treatments. The probability of hatching was not related to female size, but rather to embryo diameter at the eyed stage and the interaction between cross type and treatment, resulting in pure clear‐water crosses hatching earlier and at higher numbers.

Our study shows that effects of humic water are not uniformally negative in perch and discloses population‐dependent responses to humic water exposure during development. Our experimental design also illustrates the utility of multi‐well plates for conducting complex high‐throughput experiments beyond traditional model species and opens new possibilities for testing perch genotype–environment associations in early‐life traits.

Taken together, results of this study add to the growing evidence that humic substances may have complex effects on fish during early life, motivating further investigations on their role in shaping natural phenotypes and potential use in the applied sector.

Published: July 2024

AbstractClimate change is anticipated to cause species to shift their ranges upward and poleward, yet space for tracking suitable habitat conditions may be limited for range‐restricted species at the highest elevations and latitudes of the globe. Consequently, range‐restricted species inhabiting Arctic freshwater ecosystems, where global warming is most pronounced, face the challenge of coping with changing abiotic and biotic conditions or risk extinction. Here, we use an extensive fish community and environmental dataset for 1762 lakes sampled across Scandinavia (mid‐1990s) to evaluate the climate vulnerability of Arctic char (Salvelinus alpinus), the world's most cold‐adapted and northernly distributed freshwater fish. Machine learning models show that abiotic and biotic factors strongly predict the occurrence of Arctic char across the region with an overall accuracy of 89 percent. Arctic char is less likely to occur in lakes with warm summer temperatures, high dissolved organic carbon levels (i.e., browning), and presence of northern pike (Esox lucius). Importantly, climate warming impacts are moderated by habitat (i.e., lake area) and amplified by the presence of competitors and/or predators (i.e., northern pike). Climate warming projections under the RCP8.5 emission scenario indicate that 81% of extant populations are at high risk of extirpation by 2080. Highly vulnerable populations occur across their range, particularly near the southern range limit and at lower elevations, with potential refugia found in some mountainous and coastal regions. Our findings highlight that range shifts may give way to range contractions for this cold‐water specialist, indicating the need for pro‐active conservation and mitigation efforts to avoid the loss of Arctic freshwater biodiversity.

AbstractThe Lys mutation of the canonical histone H3.1 Glu97 residue (H3E97K) is found in cancer cells. Previous biochemical analyses revealed that the nucleosome containing the H3E97K mutation is extremely unstable as compared to the wild‐type nucleosome. However, the mechanism by which the H3E97K mutation causes nucleosome instability has not been clarified yet. In the present study, the cryo‐electron microscopy structure of the nucleosome containing the H3E97K mutation revealed that the entry/exit DNA regions of the H3E97K nucleosome are disordered, probably by detachment of the nucleosomal DNA from the H3 N‐terminal regions. This may change the intra‐molecular amino acid interactions with the replaced H3 Lys97 residue, inducing structural distortion around the mutated position in the nucleosome. Consistent with the nucleosomal DNA end flexibility and the nucleosome instability, the H3E97K mutation exhibited reduced binding of linker histone H1 to the nucleosome, defective activation of PRC2 (the essential methyltransferase for facultative heterochromatin formation) with a poly‐nucleosome, and enhanced nucleosome transcription by RNA polymerase II.
Understanding CRT and its implications for family science
Authors: Dow Dawn M. , Gordon Mellissa S. 
Published: July 2024

AbstractFamily science has been slow to incorporate critical race theory (CRT) into research on family experiences and outcomes. Discussions of CRT often reduce it to one idea when it is comprised of several key tenets, including the social construction of race, racism as normal and commonplace, critiques of the liberal state, interest convergence, counterstorytelling, intersectionality and anti‐essentialism, and Whiteness as a form of property. CRT scholars share the aim of investigating the creation, maintenance, and reproduction of regimes of White supremacy that subordinate people of color, and how such regimes might be transformed. Responding to amplified attention to racial injustices and structural racism, The National Council on Family Relations journals published special issues in 2022, inviting family scholars to submit scholarship engaging with a range of critical frameworks examining racial inequities within families, including CRT. However, many family scientists have limited exposure to CRT in their training and know little about its origins, tenets, applications, and contributions to various disciplines. There is also little understanding of the consequences of not using CRT approaches to enhance our understanding of families and what can be gained from using it. This article describes CRT's origins and key tenets scholars use in their research alongside examples of family science and related research using CRT to examine the impact of structural racism and racial inequality on the family. The article concludes by discussing how a more robust and sustained engagement with the analytical, methodological, and theoretical frameworks of CRT would enhance our understanding of families.
