Leadership style to sustain organisational culture
One of Kumba Resourcesâ strategic objectives is to create a high performance culture amongst
its employees. The Hay-group identified through worldwide studies that leadership style has a
70% influence on organisational culture, which in turn explains a 28% increase in revenues and
profits. In view of the fact that leadership can have a positive influence on the bottom line it was
identified as one of the key drivers to enhance performance. Thabazimbi iron ore mine
implemented this leadership model to impact on the culture to move towards a âhigh
performanceâ culture. Thabazimbi developed an organisational culture model that is aligned to
the foundational values (caring, accountability, fairness, integrity and respect) of Kumba
Resources. Thabazimbi is in the process of building a strong organisational culture by creating
an environment for its employees to perform in. The latest Organisational Culture Assessment
that was conducted during November 2005 indicates that Thabazimbiâs culture is a âmoderate
high performanceâ culture.Graduate School for Business LeadershipM.B.L
HOW TO CULTIVATE ANALYTICS CAPABILITIES WITHIN AN ORGANIZATION? â DESIGN AND TYPES OF ANALYTICS COMPETENCY CENTERS
Today, the ability to exploit big data using advanced analytics bears considerable potential to create competitive advantages. Therefore, business leaders need to make crucial design decisions on how to cultivate these capabilities within their organization. Analytics Competency Centers (ACCs) are an important organizational solution to spread analytics capabilities by providing leadership, expertise and infrastructure. In this paper, we analyze nine analytics competency centers of major global players across several industries - based on a series of interviews with executives, consultants and data scientists. We identify strategic and structural design options, common processes, best-practices, and potential future development paths. In particular, we distinguish between two generic types of centers that differ in their strategic orientation and their choice of design options. Our work contributes to organizational design theory addressing the question on how analytics capabilities can be nurtured for competitive advantage. It should provide concrete guidance to business leaders on how to design and apply ACCs as an organizational option
DMFC-GraspNet: Differentiable Multi-Fingered Robotic Grasp Generation in Cluttered Scenes
Robotic grasping is a fundamental skill required for object manipulation in
robotics. Multi-fingered robotic hands, which mimic the structure of the human
hand, can potentially perform complex object manipulation. Nevertheless,
current techniques for multi-fingered robotic grasping frequently predict only
a single grasp for each inference time, limiting computational efficiency and
their versatility, i.e. unimodal grasp distribution. This paper proposes a
differentiable multi-fingered grasp generation network (DMFC-GraspNet) with
three main contributions to address this challenge. Firstly, a novel neural
grasp planner is proposed, which predicts a new grasp representation to enable
versatile and dense grasp predictions. Secondly, a scene creation and label
mapping method is developed for dense labeling of multi-fingered robotic hands,
which allows a dense association of ground truth grasps. Thirdly, we propose to
train DMFC-GraspNet end-to-end using using a forward-backward automatic
differentiation approach with both a supervised loss and a differentiable
collision loss and a generalized Q 1 grasp metric loss. The proposed approach
is evaluated using the Shadow Dexterous Hand on Mujoco simulation and ablated
by different choices of loss functions. The results demonstrate the
effectiveness of the proposed approach in predicting versatile and dense
grasps, and in advancing the field of multi-fingered robotic grasping.Comment: Submitted IROS 2023 workshop "Policy Learning in Geometric Spaces
Sexual interaction in digital contexts and its implications for sexual health: a conceptual analysis
Based on its prevalence, there is an urgent need to better understand the mechanisms, opportunities and risks of sexual interaction in digital contexts (SIDC) that are related with sexual arousal. While there is a growing body of literature on SIDC, there is also a lack of conceptual clarity and classification. Therefore, based on a conceptual analysis, we propose to distinguish between sexual interaction (1) through , (2) via , and (3) with digital technologies. (1) Sexual interactions through digital technologies are face-to-face sexual interactions that (a) have been started digitally (e.g., people initiating face-to-face sexual encounters through adult dating apps) or (b) are accompanied by digital technology (e.g., couples augmenting their face-to-face sexual encounters through filming themselves during the act and publishing the amateur pornography online). (2) Sexual interactions via digital technology are technology-mediated interpersonal sexual interactions (e.g., via text chat: cybersex; via smartphone: sexting; via webcam: webcam sex/camming). (3) Sexual interactions with digital technology occur when the technology itself has the role of an interaction partner (e.g., sexual interaction with a sex robot or with a media persona in pornography). The three types of SIDC and their respective subtypes are explained and backed up with empirical studies that are grouped according to two major mediators: consent and commerce. Regarding the causes and consequences of the three types of SIDC we suggest a classification that entails biological, psychological, social, economic, and technological factors. Regarding implications of SIDC we suggest to focus on both opportunities and risks for sexual health. The proposed conceptual framework of SIDC is meant to inform future research
In vitro characterization of 177Lu-radiolabelled chimeric anti-CD20 monoclonal antibody and a preliminary dosimetry study
Purpose: 131I- and 90Y-labelled anti-CD20 antibodies have been shown to be effective in the treatment of low-grade, B-cell non-Hodgkin's lymphoma (NHL). However, the most appropriate radionuclide in terms of high efficiency and low toxicity has not yet been established. In this study we evaluated an immunoconjugate formed by the anti-CD20 antibody rituximab and the chelator DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid). DOTA-rituximab was prepared as a kit formulation and can be labelled in a short time (<20min) with either 177Lu or 90Y. Materials and methods: Immunoconjugates with different numbers of DOTA molecules per rituximab were prepared using p-SCN-Bz-DOTA. In vitro immunoreactivity and stability were tested and preliminary dosimetric results were acquired in two patients. Results: The immunological binding properties of DOTA-rituximab to the CD20 antigen were found to be retained after conjugation with up to four chelators. The labelled product was stable against a 105 times excess of diethylenetriaminepentaacetic acid (DTPA, 37°C, 7days). Two patients with relapsed NHL were treated with 740MBq/m2 body surface 177Lu-DOTA-rituximab. Scintigraphic images showed specific uptake at tumour sites and acceptable dosimetric results. The mean whole-body dose was found to be 314mGy. The administration of 177Lu-DOTA-rituximab was tolerated well. Conclusion: Our results show that DOTA-rituximab (4:1) can be labelled with 177Lu with sufficient stability while the immunoconjugate retains its immunoreactivity. 177Lu-DOTA-rituximab is an interesting, well-tolerated radiolabelled antibody with clinical activity in a low dose range, and provides an approach to the efficient treatment with few side effects for patients with relapsed NH
Liver Transplantation for Advanced Liver Disease with Alpha-1antitrypsin Deficiency
ALPHA-1-antitrypsin deficiency associated with chronic obstructive airway disease was recognized in 1963 by Laurell and Ericksson.1 In 1969, Sharp2 described the first cases of alpha-1-antitrypsin-deficiency disease in children with cirrhosis. Since then, this inborn error has been recognized as one of the more common factors in cirrhosis of infancy and childhood,3 including âneonatal hepatitis.â4 Alpha-1-antitrypsin is a glycoprotein that accounts for a major portion of the alpha-1 globulin fraction of the serum.5 It is responsible for approximately 90 per cent of the antitrypsin activity6 of the serum, and it also inhibits several other plasma enzymes, including plasmin,7 elastase,8 collagenase,9 and. © 1980, Massachusetts Medical Society.
