An Efficient Method for Supervised Hyperspectral Band Selection

Abstract: Band selection is often applied to reduce the dimensionality of hyperspectral imagery. When the desired object information is known, it can be achieved by finding the bands that contain the most object information. It is expected that these bands can provide an overall satisfactory detection and classification performance. In this letter, we propose a new supervised band-selection algorithm that uses the known class signatures only without examining the original bands or the need of class training samples. Thus, it can complete the task much faster than traditional methods that test bands or band combinations. The experimental result shows that our approach can generally yield better results than other popular supervised band-selection methods in the literature.

Toward an Interactional Conception of Community

Abstract: T IHE GROWING CONCERN of the general public and of opinion leaders for the development and preservation of the community as a social unit needs to be seen against the background of forces hastening its decline, namely, centralization, specialization, and the increase of impersonal relationships. Centralization is seen both in the massing of population and the pyramiding of power and leadership, culminating in the growth of the monolithic state.' The search for community is not confined to the devotees of the rural way of life. The supporters of urban life, principally those concerned with the neighborhoods of the central city, are becoming increasingly concerned about the urban sprawl and the "anti-city" trends in metropolitan growth.2 The many-sided community organization and community development movement of today) as seen especially by those involved, is a reaction to rapid community decline. Significant development programs are found in town and country communities and in urban neighborhoods, chiefly those in central cities.3 Community development programs in the underdeveloped nations of the world are another very rapidly expanding area of work.

The intestines of carnivorous fish: structure and functions and the relations with diet

Abstract: The intestine is a complex multifunctional organ. In addition to digesting and absorbing feedstuffs, the intestine is critical for water and electrolyte balance, endocrine regulation of digestion and metabolism, and immunity. The intestines of carnivorous fish have evolved for processing a highly digestible, nutrient dense diet that is high in protein and low in carbohydrate. Correspondingly, abilities to digest protein are well developed, but carbohydrate digestion is low compared to omnivorous and herbivorous fish. Furthermore, the evolutionary stable diet is associated with a lack or reduced abilities to adaptively modulate digestive functions to match changes in diet composition. Despite similar selective pressures, intestinal structure is highly variable among carnivorous fish, reflecting phylogenetic diversity. Due to economic considerations, diets for cultured species often have varying proportions of plant-based ingredients. Although such feeds are effective for raising omnivorous and herbivorous species, they have provided limited success for carnivores, and this has been attributed to digestive limitations. Recent evidence of inflammatory responses to as yet unidentified components of some plants suggest involvement of the enteric immune system. Changes in temperature and salinity alter intestinal structure and functions, and therefore processing of dietary inputs. A relatively unknown component of the intestine involves the resident microbiota and its role in the health and disease of carnivoraus fish.

A path model examining the relations among strategic performance measurement system characteristics, organizational justice, and extra- and in-role performance

Abstract: Economic theory suggests that multiple financial and non-financial measures (i.e., a strategic performance measurement system “SPMS”) be used in compensation contracting to properly direct employees’ attention and motivate behavior aligned with organizational goals. Conversely, linking incentives to the SPMS can result in various dysfunctional behaviors, including game playing by employees, the achievement of unbalanced performance, and the potential of basing compensation on an incomplete performance measurement system. Prior literature has investigated the use of subjectivity in compensation contracting as a means of potentially mitigating these problems; however, subjectivity can introduce other problems including claims of favoritism and bias. Economic theorists have recently begun expanding the traditional agency model to include the notion of fairness or justice. In this study, we obtain data from an organization that uses an SPMS as the basis for the allocation of bonuses and investigate whether characteristics of the SPMS are associated with perceived organizational fairness. Specifically, we hypothesize and show that the extent to which employees perceive that the SPMS reflects a strategic causal model and the degree to which it is technically valid are positively associated with their perceptions of organizational justice. We also provide evidence that heightened levels of organizational justice are the mechanism though which the perceived characteristics of the SPMS are associated with employee performance. The implication is that firms do not necessarily need to introduce subjectivity into the incentive contracting system, but can enhance performance by linking incentive contracts to their SPMS if the system contains characteristics that enhance employees’ perceptions of justice.
