This paper discusses the rise of human-centric lighting and its current status in lighting. We summarise the human benefits associated with light and lighting and show that human-centric lighting has sound motivations, despite being tainted by misleading marketing claims. The phrase integrative lighting avoids the hype and encapsulates what lighting aspires to be. Embodied in these concepts are some things old and some things new. The old is twofold. First, without diminishing the value of lighting products, the core ingredient for good human outcomes is good design, driven by a design team. Second, light is still for vision, and lighting for visibility, visual comfort and visual amenity is as important as ever. Complementing the old is new awareness and responsibility for how light and lighting influence non-visual responses in humans. Circadian, neuroendocrine and neurobehavioural responses are important for human health and should be considered on-par with visual responses. This awareness leads toward lighting design solutions with increased contrast between day and night. The parties responsible for addressing non-visual responses to light and lighting are evolving. Architects, lighting professionals, lighting equipment manufacturers, medical professionals, building owners and individuals all have a stake, but who should drive decisions and in what proportion?

As lighting designers, our work impacts people and the environment. Putting human-centric thinking and approaches at the heart of design is the first principle. This paper reflects a personal view on what lighting designers need to know before they can apply professional judgement and claim that their lighting design will improve human health.

The LHCb detector will be upgraded for the LHC Run 3. The new, full software trigger must be able to sustain the 30MHz proton-proton inelastic collision rate. The Gaudi framework currently used in LHCb has been re-engineered in order to enable the efficient usage of vector registers and of multi-and many-core architectures. This contribution presents the critical points that had to be tackled, the current status of the core software framework and an outlook of the work program that will address the challenges of the software trigger.

Abstract Artificial intelligence technology (A I T) has also been widely used in society. Combining A I T with mechanical and electrical control systems will bring huge profits to the corporate sector and greatly improve work efficiency. It can save a lot of money in the electrical control operations of all walks of life in the country, and fill the gap in this technology in the country. The purpose of this article is to study the application of A I T in mechanical electrical control systems (M E C S). This article first introduces the basic theories and concepts of A I T, extends the core technology of A I T, and combines the current status of the electrical control system of modern enterprises in our country to discuss its existing problems, and finally studies and analyzes A I T and machinery. Combination of electrical control systems, and discuss the application of A I T in mechanical electrical orifice subsystems. Experiments show that, compared with the existing M E C S, the M E C S using A I T can better complete the work and improve work efficiency.

Background/Context Research in the latter half of the 20th century purporting to show significant racial differences in intelligence and social behavior appears to pit civil rights concerns against the freedom of scientific inquiry. The core hypotheses and presumptions of recent research on racial difference are not new, however, but spring from a two-century-old program of research that has sought to demonstrate racial differences in socially valued traits. Purpose/Objective/Research Question/Focus of Study The purpose of this review was to explore the history of racial difference research in order to (1) elucidate the central themes of that research and (2) explore the reasons for the persistence of those themes into modern racial difference research. Research Design The investigation is a historical analysis of research on racial differences from the late 18th century to the present. Conclusions/Recommendations Both the methodologies and the willingness to express the core hypotheses of a fixed differential between races on socially important characteristics have changed over time, yet adherence to a set of core research questions has remained relatively unchanged across generations of researchers. Although the consistent conflation of its political and scientific aims has, to some extent, compromised the scientific status of racial difference research, consistent links to social and economic policy have also ensured its intergenerational reproduction. Convergent shifts across a number of disciplines suggest that a Kuhnian-type paradigm shift may be under way that will redefine both the strategies and the types of questions that may characterize future research in the areas of race, ethnicity, and culture.

Established in 1983, the Digital Geography Lab (DGL) at Salem State University (SSU) is one of the oldest higher-education digital spatial labs. This paper details the evolution of the DGL as well as its current status as one of the best computer labs at Salem State University. This paper describes the changing technology of the DGL over the past 28 years. The DGL not only provides SSU students with cutting edge geospatial technology, but it is a research lab for faculty and is extensively used in community outreach programs. The DGL is being used more and more by other departments such as Geology, Criminal Justice, Computer Science and Inter-disciplinary Studies which reflects the expansion of the geo-spatial sciences beyond geography. The success of the DGL lies in part with the University’s management of the facility where major decisions are made in consultation with the Department and DGL staff. The configuration and technology of the DGL has changed considerably through the years, reflecting the transformations in technology and educational philosophies, but the core mission of the DGL has not, which is to serve the students, faculty and the local community with cutting edge geospatial technology.

An increasing number of organizations are struggling to overcome “information paralysis” — there is so much data available that it is difficult to understand what is and is not relevant. In addition, managerial intuition and instinct are more prevalent than hard facts in driving organizational decisions. Organizational Data Mining (ODM) is defined as leveraging data mining tools and technologies to enhance the decision-making process by transforming data into valuable and actionable knowledge to gain a competitive advantage (Nemati & Barko, 2001). The fundamentals of ODM can be categorized into three fields: Artificial Intelligence (AI), Information Technology (IT), and Organizational Theory (OT), with OT being the core differentiator between ODM and data mining. We take a brief look at the current status of ODM research and how a sample of organizations is benefiting. Next we examine the evolution of ODM and conclude our chapter by contemplating its challenging yet opportunistic future.

The taxonomy of the T. bessonii, T. bonibony, T. dysalum, T. marginatum, T. tsingy, and T. weitzeckeri species groups isrevised. A total of 33 species is treated, of which 27 are newly described and one is raised to species status. The T.weitzeckeri group contains the single species T. humbloti Forel, which is of Afrotropical origin and the only representativeof the group in the Malagasy region. The species T. bessonii Forel, T. dysalum Bolton, T. marginatum Forel, and T. stein-heili Forel, which were originally members of the T. weitzeckeri group, are now placed in other groups. Tetramorium bes-sonii is the core species of the T. bessonii group, which also contains the four newly described species T. artemis sp. n., T.malagasy sp. n., T. ryanphelanae sp. n., T. wardi sp. n., and T. orientale Forel stat. n., which was a junior synonym of T.bessonii but is now raised to species rank. The T. dysalum group is a moderately-sized group with ten species, of whichonly T. dysalum and T. steinheili were previously known; the other eight species are all newly described. The newly described species in this group are: T. ambatovy sp. n., T. macki sp. n., T. mallenseana sp. n., T. orc sp. n., T. robitika sp. n.,T. sargina sp. n., T. yammer sp. n., and T. vohitra sp. n. A lectotype and several paralectotypes of T. steinheili are desig-nated. Tetramorium marginatum is the central species of the T. marginatum group, which also includes the five newly de-scribed species T. valky sp. n., T. hector sp. n., T. norvigi sp. n., T. shamshir sp. n., and T. silvicola sp. n. The T. bonibonyand T. tsingy groups represent completely new groups that consist entirely of previously unknown, undescribed species.The first group holds the new species T. bonibony sp. n., T. kali sp. n., T. sada sp. n., T. nosybe sp. n., T. olana sp. n., T.popell sp. n., and T. trafo sp. n. and T. vony sp. n. The last group, the T. tsingy group, only contains the two species T. tyrionsp. n. and T. tsingy sp. n., both among the rarest Tetramorium species in Madagascar. All groups are fully revised withillustrated species-level identification keys, and all species are described/re-described and illustrated with high qualitymontage images. In addition, the current status of the Malagasy Tetramorium species groups is discussed and further modifications are proposed.

The presence of arsenic in marine samples was first reported over 100 years ago, and shortly thereafter it was shown that common seafood such as fish, crustaceans, and molluscs contained arsenic at exceedingly high concentrations. It was noted at the time that this seafood arsenic was probably present as an organically bound species because the concentrations were so high that if the arsenic had been present as an inorganic species it would certainly have been toxic to the humans consuming seafood. Investigations in the late 1970s identified the major form of seafood arsenic as arsenobetaine [(CH3)3As+CH2COO–], a harmless organoarsenic compound which, following ingestion by humans, is rapidly excreted in the urine. Since that work, however, over 50 additional arsenic species have been identified in marine organisms, including many important food products. For most of these arsenic compounds, the human toxicology remains unknown. The current status of arsenic in seafood will be discussed in terms of the possible origin of these compounds and the implications of their presence in our foods.
