A Defense of Free-Roaming Cats from a Hedonist Account of Feline Well-being

There is a widespread belief that for their own safety and for the protection of wildlife, cats should be permanently kept indoors. Against this view, I argue that cat guardians have a duty to provide their feline companions with outdoor access. The argument is based on a sophisticated hedonistic account of animal well-being that acknowledges that the performance of species-normal ethological behavior is especially pleasurable. Territorial behavior, which requires outdoor access, is a feline-normal ethological behavior, so when a cat is permanently confined to the indoors, her ability to flourish is impaired. Since cat guardians have a duty not to impair the well-being of their cats, the impairment of cat flourishing via confinement signifies a moral failing. Although some cats assume significant risks and sometimes kill wild animals when roaming outdoors, these important considerations do not imply that all cats should be deprived of the opportunity to access the outdoors. Indeed, they do not, by themselves, imply that any cat should be permanently kept indoors

Sheep complexity outside the laboratory

Marino & Merskin’s review shows that sheep are intelligent and highly social but their methodology has some shortcomings. I describe five problems with reviewing only the academic and scientific literature and suggest how one might provide an even more compelling case for the complexity of sheep minds

Spacecraft surgical scrub system

Ease of handling and control in zero gravity and minimizing the quantity of water required were prime considerations. The program tasks include the selection of biocidal agent from among the variety used for surgical scrub, formulation of a dispensing system, test, and delivery of flight dispensers. The choice of an iodophore was based on effectiveness on single applications, general familiarity among surgeons, and previous qualification for space use. The delivery system was a choice between the squeeze foamer system and impregnated polyurethane foam pads. The impregnated foam pad was recommended because it is a simpler system since the squeeze foamer requires some applicator to effectively clean the skin surfaces, whereas the form pad is the applicator and agent combined. Testing demonstrated that both systems are effective for use as surgical scrubs

Don’t Demean “Invasives”: Conservation and Wrongful Species Discrimination

It is common for conservationists to refer to non-native species that have undesirable impacts on humans as “invasive”. We argue that the classification of any species as “invasive” constitutes wrongful discrimination. Moreover, we argue that its being wrong to categorize a species as invasive is perfectly compatible with it being morally permissible to kill animals—assuming that conservationists “kill equally”. It simply is not compatible with the double standard that conservationists tend to employ in their decisions about who lives and who dies

Vicia incisa (Fabaceae). Taxonomical and chorological notes

The classification of the Vicia sativa aggregate is unsatisfactory. Concerning the taxonomic value and choice of rank of some of these taxa, there are disagreements among botanists. Vicia incisa, which was originally described at species level, was mostly treated at subspecies rank of V. sativa. However, chemical and molecular data pointed out that this taxon, not only should be treated at species rank, but it should be removed from the group of V. sativa, being more related to V. barbazitae, V. grandiflora, and V. sepium. Based on morphometric measurements and cultivation tests, as well as nomenclatural investigations, the present research was carried out with the main aim to define the better taxonomic rank for the studied taxon. The results obtained support the published molecular data concerning both the recognition of the studied taxon at species level and the morphological similarity among V. incisa, V. barbazitae, V. grandiflora and V. sepium

Patterns of co-occurrence of rare and threatened species in winter arable plant communities of Italy

Detecting patterns of species co-occurrence is among the main tasks of plant community ecology. Arable plant communities are important elements of agroecosystems, because they support plant and animal biodiversity and provide ecosystem services. These plant communities are shaped by both agricultural and environmental drivers. The pressure of intensive agriculture worldwide has caused the decline of many characteristic arable species and communities. Italy is the European country where arable plant biodiversity is the best preserved. In this study, we assessed the patterns of co-occurrence of rare and threatened arable plants in 106 plots of winter arable vegetation located from Piedmont to Calabria, in the mainland part of the country. For this purpose, we based our investigation on the analysis of a recently acquired dataset and on the European list of rare and threatened arable plants. We highlight how dierent species of conservation interest tend to occur in the same community. On the other hand, generalist and more competitive taxa show similar patterns of co-occurrence. We suggest that single species of conservation value could be suitable indicators of a well-preserved community. On the other hand, to be eective, conservation strategies should target the whole community, rather than single species

The Spirituality of Addictions: A Christian Patristic Model and Procedure for Assessment

Addiction theory has focused on the debilitating effects that drug addicts and alcoholics face. However, addiction can permeate much further into our lives than just through drugs and alcohol. Evagrius of Ponticus presented eight tempting thoughts that comprised all the beliefs, behaviors, items, and emotions that an individual can be disorderly attached to. These disordered attachments can have enslaving effects on an individual that constrains the person’s will and desire for freedom from these preoccupations. We also include a measure that assesses spiritual involvement and locus of control. The purpose of this study is to compile a psychological measurement that will assess the many domains of disordered attachment an individual can encounter and the degree to which it constrains their lives. This measure will consist of approximately 75 Likert scale items that include questions pertaining to pride, emotions, relations, sexuality, avarice, power/control, and problems of desire. The factors we have derived through factor analysis allow for each participant to be scored on various subscales. These scores will indicate the specific nature of the addictive tendencies. Lastly, individuals who are found to be more spiritually involved are presumed to be less attached to the constructs mentioned above
