Enacting Resilience in Small and Medium Enterprises Following the Sustainability Path: A Systematic Literature Review
Authors: Damiano Rodolfo , Valenza Giuseppe 
Published: October 2024

ABSTRACTThis article investigates entrepreneurship literature insights into whether and how changing organizational strategies and processes toward more sustainable ones can allow small and medium enterprises (SMEs) to gain resilience. We deepen the relationship between reorienting SMEs' strategies and processes toward sustainability and gaining resilience by providing a framework and suggesting avenues for future research. Specifically, we cluster the content of 53 articles in five thematic areas using qualitative thematic analysis. These areas are “barriers, contextual factors, and government help,” “entrepreneurial orientation or attitude,” “capabilities and lean thinking,” “means and processes,” and “supply chains, synergies, and collaborations.” The findings suggest that reorienting businesses to more sustainable strategies and processes can also facilitate the shift toward more resilient business models and ecosystems. The article contributes to the literature on SMEs' resilience, binding such literature with the one on sustainable business and SMEs' sustainability, providing a theoretical framework useful for researchers, managers, and policymakers. The novelty of the work consists of emphasizing consciousness of this relationship and suggesting unexplored lines of research.

ABSTRACTBackgroundDespite the well‐known prognostic role of lymph node metastasis (LNM) in pNETs, less is known about the importance of lymphovascular invasion (LVI) among patients with these tumors.MethodsPatients undergoing pancreatectomy for pNET between 2002 and 2020 were identified in the US Neuroendocrine Tumor Study Group database. Cox regression analysis was utilized to identify the impact of LVI on recurrence‐free survival (RFS) among patients with node‐negative pNET.ResultsAmong 853 patients who underwent resection for pNET, 214 patients (25.1%) had LNM, while 116 (13.6%) and 523 individuals (61.3%) were LVI + N0 and LVI − N0, respectively. The overall incidence of LVI among patients with N0 pNET was 18.1%; the incidence of LVI increased with increasing tumor size and Ki‐67 levels (size < 2 cm and Ki‐67 < 3%: 5.5%; size < 2 cm and Ki‐67 ≥ 3%: 17.2%; size ≥ 2 cm and Ki‐67 < 3%: 22.2%; size ≥ 2 cm and Ki‐67 ≥ 3%: 43.1%, p < 0.001). Five‐year RFS was highest among patients with LVI − N0 disease followed by individuals with LVI + N0 and N+ pNETs (92.8% vs. 61.6% vs. 58.3%, p < 0.001). On multivariable analysis, the presence of LVI on pathology remained independently associated with almost 2.5 times higher hazards of recurrence (HR 2.47, 05% CI 1.44–4.24) among individuals with N0 pNETs.ConclusionThe incidence of LVI varied according to tumor size and Ki‐67. LVI was associated with a higher likelihood of recurrence among individuals who underwent formal pancreatic resection for N0 pNETs. LVI is an important prognostic indicator among patients with node‐negative pNETs.

AbstractMany large‐herbivore populations are regulated at least in part by bottom‐up forces, and thus relationships between herbivores and their habitat are of fundamental importance to wildlife managers. Variation in nutritional resources—and how herbivores respond to that variation—influences rates of nutrient intake, which directly affect nutritional condition, pregnancy rates, timing of parturition, offspring birth mass, and survival. Accordingly, nutrition‐focused research holds great potential for uncovering the mechanisms that govern population performance of large herbivores and for assessing the nature and magnitude of bottom‐up limitations. We quantified relationships between the foodscape (i.e., spatiotemporal variation in forage quality and abundance) in southwestern Oregon, USA, and black‐tailed deer (Odocoileus hemionus columbianus) behavior and performance, with a focus on the influence of maternal nutrition on fawn survival. We hypothesized that black‐tailed deer performance (i.e., fawn birth mass and survival) is influenced by the availability of high‐quality forage during spring and summer and patterns of foodscape use exhibited by individual deer. From 2016–2023 we monitored movement and survival of adult female black‐tailed deer and their offspring. We also conducted intensive vegetation sampling and used generalized additive modeling to map the foodscape available to deer in spring and summer. Suitable forage biomass (i.e., maximum biomass of forage that together exceeded quality thresholds for supporting one fawn) was highly variable across space and time, and our top foodscape model explained 70% of the variation in suitable biomass (adjusted R2 = 0.70). We observed a strong, positive relationship between use of the foodscape by maternal females prior to parturition and fawn birth mass. Although maternal foodscape use after parturition did not influence the probability of fawn survival, survival increased with increasing birth mass. These results suggest that the effects of nutrition on fawn survival in our study system are indirectly mediated by maternal behavior (i.e., use of the foodscape) and the corresponding effects on birth mass of fawns. Our study adds to a growing body of literature supporting a fundamental link between foodscape use and population performance of large herbivores. Wildlife managers can use the dynamic models we developed to assess habitat quality and to make quantitative predictions about how different management actions (e.g., forest thinning) are likely to influence habitat quality and performance of black‐tailed deer.

AbstractAn inequity persists between women and men in nearly all scientific fields. A clear indicator of this bias is the disparity between women and men in authorship of scientific papers, as publications are a critical part of a researcher's career. Our objective was to describe gender equity (sensu women, men) in wildlife‐related publishing in recent decades. We reviewed all research articles published in The Journal of Wildlife Management (JWM) from 1999 through 2020 and collected author names, affiliated institutions, and study species taxa from each paper. To help understand representation by gender in publishing, we classified the gender of each author using the online tool Genderize.io. We then calculated the women‐to‐men ratio in publishing as first‐ and co‐authors across time. We further investigated whether there were biases by country, institution, and taxon of study species. Our results revealed that authorships were dominated by men 22 years ago, with 14 and 12 women/100 men for first‐ and co‐authorships, respectively, in 1999. Since then, apart from year‐to‐year fluctuations, the overall gap between women and men gradually narrowed until the mid‐2010s, reaching approximately 60 and 30 women/100 men for first‐ and co‐authorship, respectively. The percentage of women increased across institutions, taxa, and countries during the study; however, the percentages of women associated with each institution type and most wildlife taxa were lower than the percentages of men. Although it is encouraging to see the improvement in equity in publishing since 1999, there are still substantially more men publishing than women, which indicates there is still a need to remedy known barriers and identify additional barriers that contribute to publication inequity.

AbstractPancreatic cancer (PC) is one of the most fatal malignancies, which has attracted scientists to investigate its etiology and pathogenesis. Nevertheless, the association between erythrocyte fatty acids and PC risk remains unclear. This study aimed to evaluate the association between levels of erythrocyte fatty acids and PC risk. The erythrocyte fatty acid compositions of 105 PC patients and 120 controls were determined by gas chromatography. Cases and controls were frequency matched by age and sex. Multivariable conditional logistic regression model and restricted cubic spline were applied to estimate the odds ratio with 95% confidence interval (OR, 95% CI) of erythrocyte fatty acids and PC risk. Our main findings indicated a significant negative association between levels of erythrocyte total monounsaturated fatty acids (MUFA) and n‐3 polyunsaturated fatty acids (n‐3 PUFA) and the risk of PC (ORT3‐T1 = 0.30 [0.14, 0.63] and ORT3‐T1 = 0.15 [0.06, 0.33], respectively). In contrast, erythrocyte n‐6 polyunsaturated fatty acids, specifically linoleic acid (LA) and arachidonic acid (AA) levels, were positively associated with PC incidence (RT1‐T3 = 4.24 [1.97, 9.46] and ORT1‐T3 = 4.53 [2.09, 10.20]). Total saturated fatty acid (SFA), especially high levels of palmitic acid (16:0), was positively associated with the risk of PC (ORT3‐T1 = 3.25 [1.53, 7.08]). Our findings suggest that levels of different types of fatty acids in erythrocytes may significantly alter PC susceptibility. Protective factors against PC include unsaturated fatty acids such as n‐3 PUFA and MUFA.
What controls the onset of winter stratification in a deep, dimictic lake?
Authors: Austin Jay 
Published: October 2024

AbstractThe transition from summer stratification to winter stratification is considered for deep, dimictic Lake Superior. The fall transition is dynamically distinct from the better‐studied spring transition; it is characterized by a wind‐driven collapse of weakening summer stratification, a surface‐cooling–driven period during which the water column is essentially isothermal, and eventual onset of inverse (cold upper layer) stratification, after which sub‐thermocline water temperatures are largely fixed for the rest of the season. Due to the small value of thermal expansivity near the temperature of maximum density, temperature gradients do not impart much stability to the water column, and it is difficult for winter stratification to form immediately upon dropping below the temperature of maximum density. Instead, the water column continues to cool until the thermal expansivity is sufficiently large in magnitude to allow temperature gradients to impart stability. This observation implies that the temperature locked into the deep water for the winter season will be a consequence of the specific meteorological forcing experienced in a given year; there may be long‐term climate change driven trends in the timing of the onset of stratification but not trends in winter deep‐water temperature. To address this hypothesis, 15 yr of moored temperature data collected in Lake Superior are examined, and a scaling argument and climatological data are applied to better understand interannual variability in the onset of winter stratification.

AbstractProgrammable metasurfaces provide a promising paradigm for the beamforming of electromagnetic waves in the fifth‐generation (5G) and sixth‐generation (6G) wireless communications with low cost and low complexity. However, most of the existing researches are focused on the sub‐6 GHz spectrum, which limited the gigabits per second (Gb s−1) high‐speed data transmission on future wireless network. Additionally, as a step forward in the development of intelligent metasurfaces, extra peripheral devices are often required to sense environmental variations for self‐adaptive modulations. Here, a wideband millimeter‐wave programmable metasurface is presented for peripheral‐free self‐adaptive signal enhancement in 5G/6G wireless communication. The proposed transmissive programmable metasurface consists of meta‐atoms, exhibiting efficient transmission (1 dB loss) and a stable 1‐bit phase difference from 23.7 to 32.1 GHz, effectively covering the desired 5G millimeter‐wave frequency bands: N257, N258, and N261. By integrating the self‐adaptive algorithm based on received signal intensity into the controller, the programmable metasurface can self‐adaptively establish an optimal or acceptable channel according to the predefined threshold values. To evaluate the performance of the prototype, an experiment on wavefront modulation was first conducted in a microwave chamber, verifying the wideband beamforming performance of the programmable metasurface. Moreover, self‐adaptive signal enhancement and millimeter‐wave wireless communication experiments were conducted in indoor environments, showing a maximum signal enhancement of 21.4 dB and a significant improvement in constellation. The proposed self‐adaptive wideband programmable metasurface demonstrates high potential for application in 5G/6G millimeter‐wave wireless networks.

AbstractA three‐step synthetic route is established for the synthesis of a phosphorus‐containing ε‐caprolactam derivative, starting from cyclohex‐2‐enone and diphenylphosphinous chloride, followed by a Beckmann rearrangement. 2D NMR spectroscopy reveals that the phosphorus moiety is selectively localized at the 4‐position of the caprolactam ring. Different amounts of the phosphorus‐containing comonomer are systematically incorporated into polyamide 6 by anionic ring‐opening copolymerization with ε‐caprolactam at elevated temperatures. Polymerization reactions are initiated by a latent, CO2 protected N‐heterocyclic carbene in the presence of N‐acetyl caprolactam and MgCl2. The phosphorus content is determined by inductively‐coupled plasma‐optical emission spectroscopy (ICP‐OES) analysis. Limiting oxygen indices up to 23.5 are found for polymers containing ≈1 wt.‐% of phosphorus. The thermal properties of the copolymers are determined and compared to those of polyamide 6.

AbstractBacterial infection of wound surfaces has posed a significant threat to human health and represents a formidable challenge in the clinical treatment. In this study, a novel antimicrobial hydrogel utilizing POM is synthesized as the primary component, with gelatin and sodium alginate as the structural framework. The resultant hydrogel demonstrates exceptional mechanical properties and viscoelasticity attributed to the hydrogen‐bonded cross‐linking between POM and gelatin, as well as the ionic cross‐linking between sodium alginate and Ca2+. In addition, the integration of CuS nanoparticles conferred photothermal properties to the hydrogel system. To address the concerns regarding the potential thermal damage to the surrounding normal cells, this study employs a LT‐PTT combined with CDT approach to achieve the enhanced antimicrobial efficacy while minimizing the inadvertent harm to the healthy cells. The findings suggested that POM‐based hydrogels, serving as an inorganic–organic hybrid material, will represent a promising antimicrobial solution and offer valuable insights for the development of the non‐antibiotic materials.

AbstractThe structure‐properties relationships of sustainable materials derived from biomass‐based monomers are investigated, focusing on hybrid styrene/terpene‐based copolymers with blocky microstructures, such as β‐myrcene– and β‐ocimene–styrene copolymers. The samples show complex glass transition dynamics, as evidenced by the physical aging experienced by the amorphous phase in styrene‐rich copolymers. The tendency of styrene‐ and terpene‐rich sequences to give heterogeneous morphologies with correlation strength extending over 10–40 nm is outlined, through small‐angle X‐ray scattering analysis. A new class of terpene‐based hybrid systems, holding promise for applications in surface coating technologies, is identified.

AbstractBackgroundX‐linked dystonia‐parkinsonism (XDP), a neurodegenerative movement disorder endemic to the Philippines, is primarily investigated in patients from Panay Island and the Greater Manila area. However, individuals residing in geographically distant regions may exhibit different clinical or genetic characteristics compared to those documented in earlier reports.ObjectiveThe aim was to investigate the relationship of XDP clinical features in a Mindanao cohort with modifiers of age at onset (AAO) variability and utilization of a previously reported AAO model.MethodsWe investigated clinical and genetic features in 27 XDP patients from southern Mindanao. In all patients, we genotyped the 4 polymorphisms linked to AAO.ResultsThe XDP‐relevant hexanucleotide repeat number significantly correlated with AAO in the 27 patients and explained about 68% of AAO variability. There is no statistical difference between the predicted and actual AAO.ConclusionThe AAO model may provide reliable predictions by employing the effect of XDP genetic modifiers of AAO variability.

AbstractBackgroundMovement clinical neurophysiology studies can distinguish myoclonus, tremor, and other jerky movements; however, there has been limited demonstration of their real‐world clinical impact.ObjectiveThe aim was to investigate movement study utility in clarifying movement classification and guiding patient management.MethodA retrospective study of myoclonus‐related movement studies was performed.ResultsOf 262 patients referred for consideration of myoclonus, 105 (40%) had myoclonus, 156 (59%) had no myoclonus (the commonest alternative classifications were functional jerks and tremor), and 1 was uncertain. An additional 29 studies identified myoclonus without prior clinical suspicion. A total of 119 of 134 (89%) myoclonus patients had a specific neurophysiologic subtype identified, most commonly cortical (64, 54%). Diagnostic differential narrowed in 60% of patients, and a new diagnosis was made in 42 (14%) patients. Medication changes were made in 151 patients (52%), with improvement in 35 of 51 (67%) with follow‐up.ConclusionsMovement studies effectively determined movement classification and identified unsuspected myoclonus, leading to changes in diagnosis and management. © 2024 The Author(s).

ABSTRACTBackgroundWe aimed to assess the role of the COVID‐19 pandemic in the association of clinical, physical, and psychological factors with pain in Rheumatoid Arthritis (RA) patients.MethodsWe included 103 RA patients (81.6% females; mean age 56.1 ± 13.8 years). Patients filled out the VAS‐pain, GAD‐7, PHQ‐9, MFI‐20, and B‐IPQ. Paired sample t‐tests, correlations, and multiple regression analyses were used to analyse the data.ResultsOur results showed significantly worsened pain in the data collected post‐pandemic (p ≤ 0.05). Pre‐pandemic, the final regression models showed an association between functional disability (β = 0.24; p ≤ 0.05), illness perception (β = 0.34; p ≤ 0.05) and pain. In post‐pandemic models, significant associations were found between fatigue (β = 0.33; p ≤ 0.01) and illness perception (β = 0.36; p ≤ 0.01) with pain. Positive illness perception was able to alleviate the associations between fatigue and depression with pain before and after the pandemic.ConclusionFindings indicate that patients with RA may have been negatively affected by the COVID‐19 pandemic given their vulnerability. Even though pharmacological treatment was not interrupted, post‐pandemic results showed significantly higher levels of experienced pain. Therefore, in addition to biological therapy, non‐pharmacological interventions, including psychological support aimed at diminishing negative illness perception, may be beneficial in reducing RA‐related pain, especially when dealing with a crisis.
