Introduction: Media representation of intimate partner violence (IPV) can influence public opinion and understanding of the phenomena and guide health policies. The current review has the aim to explore and discuss international, scientific literature focused on the portrayal of IPV in written forms of news media.

Method: Searching through EBSCO and PubMed, 2,435 studies were found and 41 were included in the current review.

Results: Bias in the portrayal of IPV was found within the studies included. While IPV-related news was mainly focused on male-perpetrated violence within heterosexual couples, little attention was paid to same-sex intimate partner violence (SSIPV). Newsworthy stories dominate IPV reporting within news media and a sensationalistic style was often employed. Furthermore, contextual information was often limited and the adoption of a thematic frame was rare, while news media were found to commonly employ an episodic frame. Official sources and family, friends and neighbours were the most quoted sources in news articles, while IPV experts were rarely drawn on for information. Regarding media representation of perpetrators, mainly regarding male abusers, news articles reported several reasons behind the violence with the consequence to justify and exonerate them from their responsibilities. Female perpetrators were found to be depicted, in some cases, as ‘mad’ or ‘bad’ people. Finally, victim-blaming content emerged within many of the articles included.

Conclusion: Bias in the media representation of IPV emerged in the current review, which needs to be addressed to positively influence public opinion and to promote an adequate understanding of the phenomena.

Collective Investment Schemes in Securities (‘CISS’) and Collective Investment Schemes in Property (CISP’) are common business vehicles in the South African economy. Nevertheless, there is still some uncertainty with regard to the tax treatment of these business structures, as the application of the specific income tax and capital gains tax provisions applicable to CISS and CISP results in several anomalies. The purpose of this article is to identify and highlight these anomalies by discussing the specific income tax and capital gains tax provisions applicable to CISS and CISP, and to suggest how some of these anomalies should be treated for tax purposes. It is submitted that the legislator did not consider the legal nature and practical operation of a CISS when the tax provisions for CISS were drafted. The tax treatment of CISP is also not without difficulties, especially where the CISP is constituted as an open‐ended investment company (OEIC’).

This paper aims to investigate the tensile strength of partially filled fused filament fabrication (FFF) printed parts with respect of cross-sectional geometry of partially filled test pieces. It was reported in the authors’ earlier work that the ultimate tensile strength (UTS) is inversely proportional to the cross-sectional area of a specimen, whereas the number of shells and infill density are directly proportional to the UTS with all other parameters being held constant. Here, the authors present an in-depth evaluation of the phenomenon and a parametric model that can provide useful estimates of the UTS of the printed part by accounting for the dimensions of the solid floor/roof layers, shells and infills.

It was found that partially filled FFF printed parts consist of hollow sections. Because of these voids, the conventional method of determining the UTS via the gross cross-sectional area given by A = b × h, where b and h are the width and thickness of the printed part, respectively, cannot be used. A mathematical model of a more accurate representation of the cross-sectional area of a partially filled part was formulated. Additionally, the model was extended to predict the dimensions as well as the lateral distortion of the respective features within a printed part using input values from the experimental data.

The result from this investigation shows that to calculate the UTS of a partially filled FFF part, the calculation based on the conventional approach is not sufficient. A new meta-model is proposed which takes into account the geometry of the internal features to give an estimate of the strength of a partially filled printed part that is closer to the value of the strength of the material that is used for fabricating the part.

This paper investigates the tensile strength of a partially filled FFF printed part. The results have shown that the tensile strength of a partially filled part can be similar to that of a solid part, at a lower cost: shorter printing time and lower material usage. By taking into account the geometries within a printed part, the cross-sectional area can be accurately represented. The mathematical model which was developed would aid end-users to predict the tensile strength for a given set of input values of the process parameters.

The purposes of this paper are to investigate the biotribological behaviour of Vitamin E-blended highly cross-linked ultra-high molecular weight polyethylene (HXL-UHMWPE) under multi-directional motion by using a CUMT II artificial joint hip simulator and compare it with HXL-UHMWPE and conventional UHMWPE.

The biotribological behaviour of conventional, highly cross-linked and Vitamin E-blended highly cross-linked UHMWPE acetabular cups counterfaced with CoCrMo alloy femoral head under multi-directional motion were investigated by using CUMT-II artificial hip joint simulator for one-million walking cycles. The test environment was at 36.5 ± 0.5°C and 25 per cent bovine serum was used as lubricant. A Paul cycle load with a peak of 784 N was applied; the motion and loading were synchronized at 1 Hz.

The wear resistance of Vitamin E-blended highly cross-linked UHMWPE was significantly higher than that of highly cross-linked and conventional UHMWPE. The wear marks observed from the worn surface of UHMWPE were multi-directional, with no dominant wear direction. Only abrasion occurred on the surface of Vitamin E-blended highly cross-linked UHMWPE, while yielding and accumulated plastic flow processes occurred on the surface of conventional UHMWPE and flaking-like facture and abrasion occurred on the surface of highly cross-linked UHMWPE.

Besides the prevention of oxidative degradation, blending with Vitamin E can also reduce the incidence of fatigue crack occurred in the surface layer of HXL-UHMWPE samples. Therefore, the wear resistance of HXL-UHMWPE under multi-directional motion can be further enhanced by blending with Vitamin E.

This study aims to systematically investigate the tribological behaviors of metal and polyethylene using lubricants composed of four synovial fluid (SF) components. In addition, the changes in protein conformation during wear were analyzed to establish the correlation between protein conformation and tribological properties.

A pin-on-disk tester with multidirectional sliding motion was used for tribological properties observation between metal and polyethylene pairs. Simulated SFs with four main constituents were used as the testing lubricants. Differential scanning calorimetry and Raman were used to characterize the changes in protein conformation during wear.

The coupling of lipids and hyaluronic acid further suppressed protein denaturation. The protein structures of the adsorption film and the ensnared protein chains in the friction zone were maintained to a certain extent, thus improving the friction and wear of polyethylene.

These findings established the correlation between protein conformation and friction and wear, promoting the understanding of the lubrication mechanism of artificial joints.

As a site of contestation among job seekers, workers, and managers, the bureaucratic workplace both reproduces and erodes occupational race segregation and racial status hierarchies. Much sociological research has examined the reproduction of racial inequality at work; however, little research has examined how desegregationist forces, including civil rights movement values, enter and permeate bureaucratic workplaces into the broader polity. Our purpose in this chapter is to introduce and typologize what we refer to as “occupational activism,” defined as socially transformative individual and collective action that is conducted and realized through an occupational role or occupational community. We empirically induce and present a typology from our study of the half-century-long, post-mobilization occupational careers of over 60 veterans of the nonviolent Nashville civil rights movement of the early 1960s. The fourfold typology of occupational activism is framed in the “new” sociology of work, which emphasizes the role of worker agency and activism in determining worker life chances, and in the “varieties of activism” perspective, which treats the typology as a coherent regime of activist roles in the dialogical diffusion of civil rights movement values into, within, and out of workplaces. We conclude with a research agenda on how bureaucratic workplaces nurture and stymie occupational activism as a racially desegregationist force at work and in the broader polity.

Transient climate sensitivity relates total climate forcings from anthropogenic and other sources to surface temperature. Global transient climate sensitivity is well studied, as are the related concepts of equilibrium climate sensitivity (ECS) and transient climate response (TCR), but spatially disaggregated local climate sensitivity (LCS) is less so. An energy balance model (EBM) and an easily implemented semiparametric statistical approach are proposed to estimate LCS using the historical record and to assess its contribution to global transient climate sensitivity. Results suggest that areas dominated by ocean tend to import energy, they are relatively more sensitive to forcings, but they warm more slowly than areas dominated by land. Economic implications are discussed.

Knowledge of how social movements move, diffuse, and expand collective action events is central to movement scholarship and activist practice. Our purpose is to extend sociological knowledge about how movements (sometimes) diffuse and amplify insurgent actions, that is, how movements move. We extend movement diffusion theory by drawing a conceptual analogue with military theory and practice applied to the case of the organized and highly disciplined nonviolent Nashville civil rights movement in the late 1950s and early 1960s. We emphasize emplacement in a base-mission extension model whereby a movement base is built in a community establishing a social movement school for inculcating discipline and performative training in cadre who engage in insurgent operations extended from that base to outlying events and campaigns. Our data are drawn from secondary sources and semi-structured interviews conducted with participants of the Nashville civil rights movement. The analytic strategy employs a variant of the “extended case method,” where extension is constituted by movement agents following paths from base to outlying campaigns or events. Evidence shows that the Nashville movement established an exemplary local movement base that led to important changes in that city but also spawned traveling movement cadre who moved movement actions in an extensive series of pathways linking the Nashville base to events and campaigns across the southern theater of the civil rights movement. We conclude with theoretical and practical implications.

The Corporation of the City of London are about to appoint a Public Analyst, and by advertisement have invited applications for the post. It is obviously desirable that the person appointed to this office should not only possess the usual professional qualifications, but that he should be a scientific man of high standing and of good repute, whose name would afford a guarantee of thoroughness and reliability in regard to the work entrusted to him, and whose opinion would carry weight and command respect. Far from being of a nature to attract a man of this stamp, the terms and conditions attaching to the office as set forth in the advertisement above referred to are such that no self‐respecting member of the analytical profession, and most certainly no leading member of it, could possibly accept them. It is simply pitiable that the Corporation of the City of London should offer terms, and make conditions in connection with them, which no scientific analyst could agree to without disgracing himself and degrading his profession. The offer of such terms, in fact, amounts to a gross insult to the whole body of members of that profession, and is excusable only—if excusable at all—on the score of utter ignorance as to the character of the work required to be done, and as to the nature of the qualifications and attainments of the scientific experts who are called upon to do it. In the analytical profession, as in every other profession, there are men who, under the pressure of necessity, are compelled to accept almost any remuneration that they can get, and several of these poorer, and therefore weaker, brethren will, of course, become candidates for the City appointment.
