A number of different approaches are currently available to digitally restore the symmetry of a specimen deformed by taphonomic processes. These tools include mirroring and retrodeformation to approximate the original shape of an object by symmetrisation. Retrodeformation has the potential to return a rather faithful representation of the original shape, but its power is limited by the availability of bilateral landmarks. A recent protocol proposed by Schlager and colleagues (2018) overcomes this issue by using bilateral landmarks and curves as well as semilandmarks. Here we applied this protocol to the Middle Pleistocene human cranium from Steinheim (Germany), the holotype of an abandoned species named Homo steinheimensis. The peculiar morphology of this fossil, associated with the taphonomic deformation of the entire cranium and the lack of a large portion of the right side of the face, has given rise to different hypotheses over its phylogenetic position. The reconstruction presented here sheds new light on the taphonomic origin of some features observed on this crucial specimen and results in a morphology consistent with its attribution to the Neanderthal lineage.

A 24-year-old woman was referred because of incompletely-controlled complex partial seizures. Her seizures had started at age 21, after a mild head injury with brief loss of consciousness incurred in a biking accident, and were characterized by a sensation of bright flashing lights in the right visual field, followed by numbness and tingling in the right foot, spreading up the leg and to the arm, ultimately involving the entire right side, including the face. Occasionally they spread further to involve right facial twitching with jerking of the right arm and leg, loss of awareness and, at the onset of her epilepsy, rare secondarily generalized convulsions. Seizure frequency averaged three to four per month. She was initially treated with phenytoin and clobazam and subsequently changed to carbamazepine 800 milligrams per day. She also complained that her right side was no longer as strong as her left and that it was also numb, especially the leg, but felt that this weakness had stabilized or improved slightly over the past two years.

In a recent number of The Harvard Theological Review, Professor Douglas Clyde Macintosh of the Yale Divinity School outlines in a very interesting manner the religious system to which he gives his adherence. For “substance of doctrine” (to use a form of speech formerly quite familiar at New Haven) this religious system does not differ markedly from what is usually taught in the circles of the so-called “Liberal Theology.” Professor Macintosh has, however, his own way of construing and phrasing the common “Liberal” teaching; and his own way of construing and phrasing it presents a number of features which invite comment. It is tempting to turn aside to enumerate some of these, and perhaps to offer some remarks upon them. As we must make a selection, however, it seems best to confine ourselves to what appears on the face of it to be the most remarkable thing in Professor Macintosh's representations. This is his disposition to retain for his religious system the historical name of Christianity, although it utterly repudiates the cross of Christ, and in fact feels itself (in case of need) quite able to get along without even the person of Christ. A “new Christianity,” he is willing, to be sure, to allow that it is—a “new Christianity for which the world is waiting”; and as such he is perhaps something more than willing to separate it from what he varyingly speaks of as “the older Christianity,” “actual Christianity,” “historic Christianity,” “actual, historical Christianity.” He strenuously claims for it, nevertheless, the right to call itself by the name of “Christianity.”

Children are afforded a number of protections when they encounter the criminal justice system. The need for special protection stems from the vulnerable position children occupy in society. When children form part of the criminal justice system, either by being an offender, victim, or witness, they may be subjected to harm. To mitigate against the potential harm that may be caused, our law provides that criminal proceedings involving children should not be open to the public, subject to the discretion of the court. This protection naturally seems at odds with the principle of open justice. However, the courts have reconciled the limitation with the legal purpose it serves. For all the protection and the lengths that the law goes to protect the identity of children in this regard, it appears there is an unofficial timer dictating when this protection should end. The media have been at the forefront of this conundrum to the extent that they believe that once a child (offender, victim, or witness) turns 18 years old, they are free to reveal the child's identity. This belief, grounded in the right to freedom of expression and the principle of open justice, is at odds with the principle of child's best interests, right to dignity and the right to privacy. It also stares incredulously in the face of the aims of the Child Justice Act and the principles of restorative justice. Measured against the detrimental psychological effects experienced by child victims, witnesses, and offenders, this article aims to critically analyse the legal and practical implications of revealing the identity of child victims, witnesses, and offenders after they turn 18 years old.

Abstract This paper describes a systematic approach to analyzing manufacturability of parts produced using Solid Freeform Fabrication (SFF) processes with flatness, parallelism and perpendicularity tolerance requirements on the planar faces of the part. SFF processes approximate objects using layers, therefore the part being produced exhibits stair-case effect. The extent of this stair-case effect depends on the angle between the build orientation and the face normal. Therefore, different faces whose direction normal is oriented differently with respect to the build direction may exhibit different values of inaccuracies. We use a two step approach to perform the manufacturability analysis. We first analyze each specified tolerance on the part and identify the set of feasible build directions that can be used to satisfy that tolerance. As a second step, we take the intersection of all sets of feasible build directions to identify the set of build directions that can simultaneously satisfy all specified tolerance requirements. If there is at least one build direction that can satisfy all tolerance requirements, then the part is considered manufacturable. Otherwise, the part is considered non-manufacturable. Our research will help SFF designers and process providers in the following ways. By evaluating design tolerances against a given process capability, it will help designers in eliminating manufacturing problems and selecting the right SFF process for the given design. It will help process providers in selecting a build direction that can meet all design tolerance requirements.

Abstract This paper examines the right to freedom of thought in the European Convention on Human Rights against the background of technological developments in neuroscience and algorithmic processes. Article 9 echr provides an absolute right to freedom of thought when the integrity of our inner life or forum internum is at stake. In all other cases, where thoughts have been manifested in some way in the forum externum, the right to freedom of thought is treated as a qualified right. While Article 9 echr is a core focus of this paper, we argue that freedom of thought is further supported by Articles 8, 10 and 11 echr. This complex of rights carves out breathing space for the individual’s personal development and therefore supports the enjoyment of freedom of thought in its fullest sense. Charged with ‘maintaining and promoting the ideals and values of a democratic society’ as well as ensuring that individual human rights are given ‘practical and effective protection’, this paper predicts that the ECtHR will make greater use of the right to freedom of thought in the face of the emerging challenges of the Fourth Industrial Revolution.

Professor van Biervliet has now completed his very careful study of right-sidedness and left-sidedness (already summarised in the Journal) by a still more careful investigation of ambidextrous persons. In the first place by photography, according to a special and uniform method, he finds that in the ambidextrous the two sides of the face, as well as the arms, are fairly alike, the face being slightly more developed on the right side, as among left-sided people, but not in so marked a degree. They occupy much the same position, indeed, throughout the investigation. When compared with right-sided and left-sided people as regards sensory acuteness, it is found that while the right-sided have predominant sensory acuteness on the right side, both the left-sided and the ambidextrous can see further, hear better, possess more acute tactile and muscular sense, on the left side, so that ambidexterity may be regarded as a variety of left-sidedness of more symmetrical anatomical type. In all respects the ambidextrous almost or quite resembled the left-sided.

OBJECTIVE: Trigeminal neuralgia is the most common facial pain. It may be treated with percutaneous balloon compression (PBC), which is considered to be a safe and efficient procedure. The purpose of this study was to review our results with PBC and to assess the factors influencing the outcome. METHOD: A multivariate analysis was used to study 39 patients during a 50-month postoperative period. RESULTS: There was predominance of the female gender (54%), the right side of the face (84%) and V2V3 roots of trigeminal nerve (33%). The mean age was 62.3 years. No major complications or deaths occurred. Among all variables, postoperative hypoesthesia was the single prognostic factor capable of positively influencing the results (p=0.02). Most patients (80%) were pain-free after 50 months with a 90% satisfaction rate. CONCLUSION: PBC was a safe procedure with low morbidity, no mortality, high approval ratings, and was an important improving on patients' quality of life.

Many in the environmental movement have argued in recent years that in order to speed up climate actions we should take the ethics out of the climate change debate. Focusing on the moral obligation to act or on the effects of climate change on the most vulnerable was often judged to render the discourse too “heavy,” “negative,” or “difficult.” Many also deemed it unnecessary. After all, renewable energies, better designed cities that allow for reduced car use, and power plant regulations that lead to cleaner local air—to take just three examples—all have real and substantial benefits unrelated to the fact that they are “the right thing to do” in the face of climate change. They create jobs, reduce health problems and costs, and make society fitter.

The freedom of the individual can easily come into conflict with his or her obligation to integrate in society. The case of Belcacemi and Oussar v Belgium provides a good example. It is evident that some restrictions of citizens’ freedoms must be accepted for a state to function and, more basically, persist; as a consequence, it is acceptable that certain demands, incorporated in criminal law, are made of citizens. The issue of the extent to which such restrictions are justified has increasingly become a topic of discussion. The present case raises a number of important questions with respect to the right to wear a full-face veil in public if the societal norm is that the face should be visible, the most salient of which are whether women should be ‘protected’ from unequal treatment against their will and to what extent society may impose values on the individual. I will argue that Belgian law places unwarranted restrictions on citizens and that the values behind it testify to an outlook that is difficult to reconcile with the freedom of conscience and religion.
