Employees' perception of corporate social responsibility and performance: the mediating roles of job satisfaction, organizational commitment and organizational trust

Purposeorporate social responsibility (CSR) is an evolving concept which is increasingly being adopted by companies with the purpose of creating sustained organizational growth. However, while the impact of CSR practices on employees' behaviors and attitudes has been recognized over the years, the relationship between CSR practices and employee performance remains underexplored.Design/methodology/approachDrawing on social identity theory and using the partial least squares structural equation method, this research examines the impact of CSR practices on employees' performance in a sample of 171 employees belonging to the construction industry.FindingsThe findings do not support the existence of a direct relationship between employees' perception of CSR and their performance; instead, they indicate that this relationship is mediated by job satisfaction and organizational trust.Research limitations/implicationsThe data concerns employees' self-reported measures on their perceived CSR and the study was conducted in a single industry.Practical implicationsAdopting CSR initiatives in company strategies is worthy as the perceptions of employees and their performance is positively influenced by their organization's CSR activities. Managers should properly communicate and involve internal stakeholders in socially responsible practices to increase their awareness.Originality/valueThis article analyzes the impact of employees' perception of CSR on employees' performance through the roles of employee organizational trust and job satisfaction as mediating variables in a highly socially pressured industry such as construction.
A New Ornithocheirid Pterosaur from the Upper Cretaceous (Cenomanian—Turonian) Eagle Ford Group of Texas

North American pterosaurs are edentulous with the exception of Coloborhynchus (Lee, 1994). In contrast, toothed pterosaurs be longing to the Ornithocheiridae are widely distributed and abun dant in other parts of the world at this time, with documented occurrences on every continent except Antarctica (Molnar and Thulborn, 1980; Lee, 1994; Mader and Kellner, 1999; Kellner and Tomida, 2000; Unwin, 2001; L? and Ji, 2005; Unwin and Mar till, 2007). The specimen described here, consisting of a nearly complete lower jaw, represents only the second documented oc currence of an ornithocheirid pterosaur in North America. Fur thermore, this specimen represents one of the youngest defini tive occurrences of the Ornithocheiridae. Discovered in the mid
Outcome after proton beam therapy versus photon-based radiation therapy in childhood-onset craniopharyngioma patients—results of KRANIOPHARYNGEOM 2007

Background Proton beam therapy (PBT) is being increas16ingly used to treat residual craniopharyngioma (CP) after hypothalamus-sparing surgery. Compared to photon-based radiation therapy (XRT) with PBT, less irradiation in the penumbra reduces the scattered dose to critical organs neighboring but outside the area of treatment, minimizing the risk of sequelae. Patients and methods Between 2007 and 2019, 99 of 290 (34%) childhood-onset CP patients recruited in KRANIOPHARYNGEOM 2007 received external radiation therapy (RT) (65% PBT, 35% XRT). Outcome was analyzed in terms of survival, endocrinological and anthropometric parameters (BMI and height SDS), quality of life (QoL using PEDQOL), and functional capacity (FMH) with special regard to irradiation technique. Results PBT became predominant (used in 43% and 72% of all irradiated patients registered within the first and second halves of the recruitment period, between 2008 and 2013 and 2013 and 2018, respectively). Five-year event-free survival rates after PBT or XRT were comparable (92% ± 4% vs. 91% ± 4%, p = 0.42) and higher than for the whole cohort since diagnosis, including non-RT patients (37% ± 4%). Radiation doses to the hypothalamus and pituitary did not differ between PBT and XRT. Endocrine deficits due to disturbances of the hypothalamic-pituitary axis (HPA) were already common before irradiation. During the first 5 years after CP diagnosis/RT, no differences between PBT, XRT, and non-RT CP patients concerning functional capacity and anthropometric parameters have been obtained. Only for the PEDQOL domain “physical function”, parental-assessed QoL was lower 12 months after PBT versus XRT or non-RT patients. Conclusion QoL, functional capacity, degree of obesity, and endocrinopathy varied over time from diagnosis, but by 5 years, there was no significant difference between PBT and XRT upfront or delayed, nor was there any compromise in historic survival rates, which remained high >90%. RT of any type is extremely effective at stabilizing disease after hypothalamic-sparing surgery. The purported specific benefits of PBT-reducing sequelae are not proven in this study where the organ of critical interest is itself diseased, increasing an urgent need to better address and treat the tumor-induced endocrine harm from diagnosis in dedicated pituitary services. Other hypothesized benefits of PBT versus XRT on vascular events and secondary cancers await longer comparison.

Polynapthalene Sulfonate Superplasticizer for Oil well Cementing: Effect on Compressive Strength

A superplasticizer or dispersant acts as a friction reducer to enhance the rheological properties of cement slurry, thereby eliminating the need for high pump pressure to pump the viscous slurry behind the casing. Polynaphthalene sulfonate (PNS) is a common dispersant for well cement; however, with the emergence of geopolymer technology for oil wells, the application of PNS in the industry has yet to be investigated. The focus of the research is to examine the influences of PNS on the early, medium, and final compressive strength of geopolymer cement cured at 3000 psi and 100 °C with PNS concentration ranging from 0.0 to 2.0 by weight of fly ash (bwof %). The findings show that PNS can increase the 8-hour compressive strength of geopolymer cement, but it can decrease the 24-hour compressive strength. However, only the sample with the highest concentration of PNS exhibits better compressive strength than the control sample at 48 hours. Additionally, the results demonstrate that the compressive strength of geopolymer cement with PNS increases with a longer curing duration. It is advisable to run a prediction plot to determine the optimum concentration that can result in high compressive strength for 8, 24 and 48 hours.
Durability and Accelerated Ageing of Natural Fibers in Concrete as a Sustainable Construction Material

This paper presents an experimental study on the influence of alkaline environments on natural fibers of plant and mineral origin in concretes. The durability of concrete-based composite materials is influenced by the properties of the reinforcing fiber, and the serviceability of concrete is dependent on its durability. The aim of the present study is to investigate the strength, weight loss %, and surface degradation of jute, sugarcane, coconut, sisal, as well as basalt fibers through an accelerated aging method when used as reinforcements in concrete. The samples were immersed in an alkaline environment of sodium and calcium hydroxide at two different levels of pH for one week. Further, the fibers were immersed in NaOH and Ca(OH)2 solutions of 1 M, 2 M, 4 M, and 6 M concentrations for 48 h in order to investigate the gradual effect of an alkaline environment on the mechanical properties of the fiber. It was concluded that the weight loss % was greatest for jute fibers when used in concrete composite, while there was no significant effect on the basalt fiber samples. The strength of jute fiber in the concrete sample was also most severely affected by the aging process, compared to other fibers. The strength of basalt fibers in a concrete composite was least affected by the aging process. In some cases, the sisal fiber sample showed an increase in fiber tenacity after the aging process due to fibrillation, which might have increased the interfacial area. The fiber microstructure before and after the aging was evaluated through the use of scanning electron microscopy (SEM). SEM analyses of different fibers were carried out to investigate surface degradation. The fiber pull-out strength was found to be the greatest for basalt fiber, followed by jute and sisal. This is indicative of the excellent adhesion of such fibers with cement in a concrete composite. In these cases, the use of sisal fiber results in defibrillation and increased specific surface area. Sugarcane and coconut fibers ruptured due to their inherent weakness and provided only a small increment in the mechanical performance of the concrete. Basalt fiber-reinforced concrete offered the greatest compressive strength, followed by jute and sisal. These observations provide crucial information regarding the durability and aging of natural fiber-reinforced concrete.
Edinburgh Research Explorer Simultaneous removal of Cr(VI) and 4-chlorophenol through photocatalysis by a novel anatase/titanate nanosheet composite: Synergetic promotion effect and autosynchronous doping

Clean-up of wastewaters with coexisting heavy metals and organic contaminants is a huge issue worldwide. In this study, a novel anatase/titanate nanosheet composite material (labeled as TNS) synthesized through a one-step hydrothermal reaction was demonstrated to achieve the goal of simultaneous removal of Cr(VI) and 4-cholophenol (4-CP) from water. TEM and XRD analyses indicated the TNS was a nano-composite of anatase and titanate, with anatase acting as the primary
Mineralogy of major soils of Punjab (Pakistan) by X-ray diffraction

The results obtained from investigation of soil samples collected from different units of Punjab like agricultural, commercial and industrial units are reported and analyzed in this paper. XRPD studies from various units showed that the phases present in the soil samples were Quartz (SiO2), Calcite (CaCO3), Albite NaAlSi3O4, Chlinochlore Mg5Al(Si,Al)4O10, Illite {(K.H3O) Al2Si3AlO10(OH)2, Vermiculite {Mg(Mg,Fe)3 (Si.Al)4 O10(OH)2.4H2O}, Gypsum (CaSO4.2H2O), Talcum {Mg3Si4O10(OH)2)}, Aluminate Al2O3, Chamosite (Fe,Al,Mg,Mn)6 (Si,Al)4O10(OH)8, Dolomite (Ca,Mg)CO3 and Epidote Ca2(Al,Fe)3 (SiO2O7) (SiO4)(OH)2. The result and mean values of concentrated data in weight %age of phases showed that Quartz, Illite, Albite and Calcite were the major constituents of the soil of Narowal and Faisalabd, while Quartz, Illite and Chamosite were the major constituents of soil in Multan. But, all other phases appeared as minor components of the soil. These were present in very small amount in the soil. From the plot of the comparison of the mean weight percentage of phases, it was clear that Illite was major phase in largest amount (53.27%, 42.62%) in the soil of Faisalabad and Narowal respectively, while Quartz (SiO2) appeared as the major phase in the largest amount (68.83%) in the soil of Multan. The special sample S-1 showed that some minerals which were already present in the soil of Narowal and Faisalabad disappeared after combining the soil samples. It means that there was a chemical phase which not only became the reason for disappearance of the minor phases but also affected the values of major phases. The appeared phases were Q, CAL and ILL while the disappeared phases were AL, CL, G, T and AM. In the same way, in the special sample S-2, CH, DL and EP did not appear after combining all the samples of Multan.
Climate Crisis and Social Protection - From Worker Protection to Post-growth Transformation?

The article discusses five literature strands’ approaches towards social protection systems in the context of climate crisis: Adaptive Social Protection, Just Transition, Green New Deal, Post-growth, and Eco-feminism. As we argue, these five strands are located on a spectrum between a green growth orientation and a green anti-capitalist orientation. Furthermore, they differ in terms of their problematisation of the climate crisis and have different perspectives on relevant actors, on world regions, and – most relevant in the context of social welfare – their conceptualisation of social protection. While Adaptive Social Protection emphasizes cash transfers and insurances, Green New Deal and Just Transition approaches focus more on redistribution and labour market policies, and Post-growth and Eco-feminist approaches more on universalist policies and systems. We argue that these literatures each have their weaknesses, but also offer urgent questions, concepts, and insights for further social policy research.
T5-like phage BF23 evades host-mediated DNA restriction and methylation

Abstract Bacteriophage BF23 is a close relative of phage T5, a prototypical Tequintavirus that infects Escherichia coli. BF23 was isolated in the middle of the XXth century and was extensively studied as a model object. Like T5, BF23 carries long ∼9.7 kb terminal repeats, injects its genome into infected cell in a two-stage process, and carries multiple specific nicks in its double-stranded genomic DNA. The two phages rely on different host secondary receptors—FhuA (T5) and BtuB (BF23). Only short fragments of the BF23 genome, including the region encoding receptor interacting proteins, have been determined. Here, we report the full genomic sequence of BF23 and describe the protein content of its virion. T5-like phages represent a unique group that resist restriction by most nuclease-based host immunity systems. We show that BF23, like other Tequintavirus phages, resist Types I/II/III restriction–modification host immunity systems if their recognition sites are located outside the terminal repeats. We also demonstrate that the BF23 avoids host-mediated methylation. We propose that inhibition of methylation is a common feature of Tequintavirus and Epseptimavirus genera phages, that is not, however, associated with their antirestriction activity.
Altered Clock Gene Expression in Female APP/PS1 Mice and Aquaporin-Dependent Amyloid Accumulation in the Retina

Alzheimer’s disease (AD), the most prevalent form of dementia, is a neurodegenerative disorder characterized by different pathological symptomatology, including disrupted circadian rhythm. The regulation of circadian rhythm depends on the light information that is projected from the retina to the suprachiasmatic nucleus in the hypothalamus. Studies of AD patients and AD transgenic mice have revealed AD retinal pathology, including amyloid-β (Aβ) accumulation that can directly interfere with the regulation of the circadian cycle. Although the cause of AD pathology is poorly understood, one of the main risk factors for AD is female gender. Here, we found that female APP/PS1 mice at 6- and 12-months old display severe circadian rhythm disturbances and retinal pathological hallmarks, including Aβ deposits in retinal layers. Since brain Aβ transport is facilitated by aquaporin (AQP)4, the expression of AQPs were also explored in APP/PS1 retina to investigate a potential correlation between retinal Aβ deposits and AQPs expression. Important reductions in AQP1, AQP4, and AQP5 were detected in the retinal tissue of these transgenic mice, mainly at 6-months of age. Taken together, our findings suggest that abnormal transport of Aβ, mediated by impaired AQPs expression, contributes to the retinal degeneration in the early stages of AD.
Children with developmental coordination disorder are less able to fine-tune muscle activity in anticipation of postural perturbations than typically developing counterparts

The majority of children with developmental coordination disorder (DCD) struggle with static and dynamic balance, yet there is limited understanding of the underlying neuromechanical mechanisms that underpin poor balance control in these children. Eighteen children with DCD and seven typically developing (TD) children aged 7–10 years stood with eyes open on a moveable platform progressively translated antero-posteriorly through three frequencies (0.1, 0.25 and 0.5 Hz). Myoelectric activity of eight leg muscles, whole-body 3D kinematics and centre of pressure were recorded. At each frequency, postural data were divided into transition-state and steady-state cycles. Data were analyzed using a linear mixed model with follow-up Tukey’s pairwise comparisons. At the slowest frequency, children with DCD behaved like age-matched TD controls. At the fastest frequency, children with DCD took a greater number of steps, had a greater centre of mass variability, had a greater centre of pressure area, and tended to activate their muscles earlier and for longer than TD children. Children with DCD did not alter their postural response following prolonged exposure to platform movement, however they made more, non-structured postural adjustments in the medio-lateral direction as task difficulty increased. At the faster oscillation frequencies, children with DCD adopted a different muscle recruitment strategy to TD children. Activating their muscles earlier and for longer may suggest that children with DCD attempt to predict and react to postural disturbances, however the resulting anticipatory muscle excitation patterns do not seem as finely tuned to the perturbation as those demonstrated by TD children. Future work should examine the impact of balance training interventions on the muscle recruitment strategies of children with DCD, to ensure optimal interventions can be prescribed.

Quantification of hydrodynamic effects on capillary seal capacity

Whether a reduction in overpressure across a hydrocarbon column and its seal will reduce the column height that the seal is capable of supporting has been much debated. Recent studies have focused on measuring water relative permeability at high capillary pressure, and have concluded that hydrocarbon columns may be sufficiently permeable to water for the seal capacity to be unaffected by hydrodynamic flow in most situations. A new method for estimating the capillary seal capacity is developed which properly takes into account viscous as well as gravity and capillary forces. A reassessment of existing analyses indicates that hydrodynamic flow has a greater influence on the seal capacity than previously thought. Sets of sensitivity models, including a range of reservoir and seal geometrical and petrophysical characteristics, indicate that – as a general rule – hydrodynamic flow should not be neglected when assessing capillary seal capacity. The sealing capacity of thick top seals above reservoirs with a basal aquifer are least likely to be affected by hydrodynamic flow. The sealing capacity of membrane fault seals, irrespective of whether they have a basal or edge aquifer, may be influenced by realistic overpressure differences. Simple end-member equations define the possible influence of hydrodynamic flow in a particular situation, and only if this is significant should a more comprehensive evaluation be considered.
A Global Hypothesis for Women in Journalism and Mass Communications

This article examines the status of women in communications industries and on university faculties. It specifically tests the Ratio of Recurrent and Reinforced Residuum or R3 hypothesis, as developed by Rush and colleagues in the early 1980s. The R3 hypothesis predicts that the percentage of women in the communications industries and on university faculties will follow the ratio residing around a 1/4:3/4 or 1/3:2/3 proportion females to males. This article presents data from a nationwide US survey and compares them to data from global surveys and UN reports. The evidence is overwhelming and shows the relevance and validity of the R3 hypothesis across different socioeconomic and cultural contexts. The article argues that the ratio is the outcome of systemic discrimination that operates at multiple levels. The obstacles to achieving equality in the academy as well as media industries are discussed and suggestions for breaking out of the R3 ratio are included.
Quality and Yield Rate of Wheat Grown in Organic Farming

Bread wheat (Triticum aestivum L.) is the most frequent cereal species in the Czech Republic grown in accordance with the organic farming principles. The range of cultivars is wide there; the organic farmers deal with a problem - how to understand it and orientate themselves in it. Our research aimed at an evaluation of the yield rate and the basic parameters of the baking quality of different winter wheat cultivars. The trial plants were grown in accordance with the organic farming principles between 2006 and 2011. The research outputs have shown that the organic growing of wheat is connected with a reduction of the yield rate, as well as the technological quality. The proportion of proteins in grain, just as the baking quality of proteins, decreases (the reduced values of the Zelenyho test). Our research has, however, shown a favorable yield rate and a good protein content of the following cultivars: Akteur, Ludwig or Element.
