Preliminary evaluation of Italian everbearing strawberry cultivars using a qualitative integrated approach

Giuggioli N.R. , Briano R. , Alvariza P., Peano C. (2018): Preliminary evaluation of day-neutral strawberry cultivars cultivated in Italy using a qualitative integrated approach. Hort. Sci. (Prague), 45: 29–36. In this study the texture profile, total soluble solids (TSS) and the fruit skin colour of four day-neutral strawberry cultivars cultivated in Italy (‘Anabelle’, ‘Murano*’, ‘Portola*’ and ‘Triumph’) was evaluated at four harvest times. The interrelationships of the analysed parameters were determined using principal component analysis in order to suggest the best commercial scenario (local market, supermarket retailer or export) for each cultivar. Data analysis related to texture and TSS contents revealed that ‘Anabelle’, ‘Portola*’ and ‘Murano*’ displayed unique characteristics, and that ‘Triumph’ showed lower values for these parameters. Due to its low hardness and cohesiveness values ‘Anabelle’ could be suited to a short supply chain; ‘Portola*’, meanwhile, might meet the requirements of a long supply chain, due to its high hardness and low TSS (P £ 0.05); ‘Murano*’ could be distinguished from the other cultivars by its high luminosity (ranging from 41.46–46.21 L*); while ‘Triumph’, due to its darkness (36.83–37.13 L*), could be suitable for a local/farmers’ market.
Assessing Topic Models: How to Obtain Robustness?

In this work we investigate the influence of varying daily activity dataset characteristics on topic model performance stability for daily routine discovery. For this purpose, we denote a set of key dataset properties that influence the experimental design regarding recording, as well as data pre-processing steps. Using generated daily activity datasets, we identified optimal topic model stability for particular dataset properties. Results indicated that topic model routine duration should exceed document size by a factor of more than two. Recording durations of more than 9 days were required for a set of four routines and activity primitive overlap may not exceed 5%.

Bullying Problems among School Children

Abstract This paper examined the problems of bullying in schools. The paper is a position paper. The term bullying refers to physical, verbal and psychological attacks intended to induce fear and distress or to inflict physical harm upon victim. Physical attacks between peers were traditionally categorized as rough play and integrated parts of students’ culture. The victims of bullying can have a variety of psychological problems such as: low self confidence, feeling of worthlessness; and low self esteem. The study advocates that bullying should not be viewed as an integral part of growing up but as an antisocial behavior associated with public health problems. The authors suggested ways to prevent and stop bullying in our schools.
General second-rank correlation tensors for homogeneous magnetohydrodynamic turbulence

The properties and structure of second-order ~Cartesian! correlation tensors are derived for the general case of two solenoidal random vector fields. The theory is intended to describe homogeneous magnetohydrodynamic turbulence, with no assumed rotational or reflectional symmetries. Each correlation tensor can be written in terms of four scalar generating functions and the relationship of these functions to the potentials that generate the poloidal and toroidal components of the underlying vector fields is derived. The physical nature of the scalar functions is investigated and their true or pseudoscalar character is ascertained. In our general discussion we clarify several misleading statements dating back to Robertson’s original paper in the field @Proc. Camb. Philos. Soc. 36, 209 ~1940! #. It is also shown that using the one-dimensional correlation function, it is possible to obtain spectral information on the induced electric field in directions perpendicular to the measurement direction. @S1063-651X~97! 09208-8#
Data Identity Provable For Multi Clouds With Freezing Safeguards

A standout amongst the most critical current examinations in the Cloud Computing provisioning is the Service Level Agreement and its application in guaranteeing the supplied distributed computing administrations. The method for giving dispersed administrations has been re-imagined as an outcome of utilizing distributed computing which as a part of turn has acquainted new difficulties with both suppliers and shoppers. Measuring the nature of distributed computing procurement from the customer's perspective is imperative so as to guarantee that the administration fits in with the level determined in the understanding; this is generally alluded to as Quality of Experience. There has been some exertion in measuring the Quality of Service as a strategy for guaranteeing the administration level in distributed computing. One of the difficulties with measuring the Quality of Experience parameters is that huge numbers of the parameters. Are subjective, and consequently makes it hard to characterize a measured metric to be utilized for instrumenting the supplied administration. This paper portrays a work-in-advancement explore that endeavours to characterize an evaluated metric that can be utilized as an execution measure to benchmark SaaS applications in distributed computing. Such a metric will be valuable to cloud suppliers and also purchasers for guaranteeing that the conveyed administrations meet the client needs. The distributed computing applications brings another arrangement of data security issues. The cloud security model in view of SLA (Service Level Agreement) was concentrated on. From the security difficulties of distributed computing , distributed computing security dangers was dissected extensively, the administration level understandings was extended, the CSLA (Cloud Service Level Agreement) structure was proposed, the cloud security reference system was planned, the cloud security level structural engineering and cloud administrations estimating and charging models was proposed.

Strengthening and repairing relationships: Addressing forgiveness and sacrifice in couples education and counselling

For many years, couples research has focused a great deal on marital distress and dissolution and, in particular, the types, frequency and management of conflict. However, some researchers are suggesting that there are limitations to the efforts being made to understand couple relationships through a narrow conflict lens. In a 2007 article in the Journal of Marriage and Family, three noted relationships scholars suggested that the accumulating evidence on conflict in relationships shows that it may be less central to long-term relationship outcomes than has been thought. They suggested that a richer understanding of couple relationships might be gained by moving the focus of research towards examining the "larger meanings and deeper motivations about relationships" and the positive constructs underlying behaviours and attitudes that help to strengthen and repair a relationship (Fincham, Stanley, & Beach, 2007, p. 276; see also Stanley, 2007; Stanley & Markman, 1998). Fincham et al. also suggested that, in taking this broader view, further mechanisms for understanding relationships may be revealed, although constructs relating to the more positive aspects of relationships seem to be more difficult to investigate. Their suggestion of shifting the focus of relationships research was met with cautious enthusiasm by a number of relationships scholars. Nevertheless, intuitively it makes sense that studying the constructs that are manifest in a range of pro-relationship behaviours and attitudes is likely to contribute to our understanding of the complexities of couple relationships. These investigations would also build on other major shifts in the focus of relationships researchers in recent years, such as the highly productive application of attachment theory to adult intimate relationships, from which therapeutic applications have also been developed. Such a move would also reflect a broader shift towards viewing relationships in terms of their strengths and wellbeing rather than deficits and distress, also evident in both research and public policy (see, for example, Ooms & Wilson, 2004). This "shift" per se is not the primary focus of this paper. Rather, it is concerned with the notion that better understanding of relational dynamics can be gained through studying constructs that contribute to the strength of a relationship.

Towards an Effective Audit Committee Role in Corporate Governance in Libyan Banks: Composition Criteria and Membership Requirements

This study examines the criteria for audit committee composition and its membership requirements within the context of effective corporate governance in Libyan banks. Members of audit committees at Libyan banks, directors of internal audit departments, and members of board of directors at these banks in addition to a number of external auditors and academicians from Libyan universities were targeted by a structured questionnaire. The participants emphasized the importance of a well written charter stating the committee's responsibilities as an essential starting point. Other criteria considered important include quarterly regular meetings, sufficient size, non-executive chairperson and the committee to report to the board of directors regarding its duties and responsibilities. The results indicate that independent audit committee members with financial literacy and accounting expertise as well as banking business knowledge are significant ingredients to ensure an effective audit committee performing corporate governance. The findings provide regulators and researchers with a foundation upon which a model of audit committees' formation and structure in Libyan banks can be formulated. Keywords : audit committee composition, membership requirements, corporate governance, Libyan commercial banks.
Environmental Indicators for the Coastal Region of the North American Great Lakes: Introduction and Prospectus

ABSTRACT The Great Lakes coastal region is a dynamic area at the interface between land and water. It is heavily influenced by the magnitude of the large lakes themselves, by natural abiotic and biotic processes in the watershed, and especially by human activity. This special issue contains a series of 21 papers that are organized into four major themes: 1) landscape characterization and coastal linkage, 2) integration, 3) indicator development, and 4) supporting information. The results of these papers emphasize that many environmental response signals are linked to their physiobiogeographic location in the basin and with human activity in coastal watersheds or in the immediate coastal margin. If lake levels continue to fluctuate and decline, if the climate continues to warm, if agricultural activity expands, if exotic species continue to invade, and if the human population density in the watershed increases, then environmental indicators of the Great Lakes coastal region reported here will point to further degradation of water quality and native amphibian, bird, diatom, fish, macroinvertebrate, and wetland plant communities. These environmental indicators are benchmarks for the current conditions of the Great Lakes coastal region and provide measurable endpoints to assess the success of future management, conservation, protection, and restoration of this important resource.
Numerical study of the vibrations of an elastic container filled with an inviscid fluid

We investigate numerically the vibrational behavior of an elastic structure containing an inviscid fluid with a filling hole where the pressure is prescribed. The underlying mathematical model is detailed and its spectra is characterized. The finite element method relies upon the added‐mass formulation of Morand and Ohayon but avoids the explicit assembly of the dense added‐mass matrix. A parametric study allows to characterize the system's response to dimensionless parameters in terms of eigenfrequencies. The resulting mode shapes are then physically discussed, with emphasis on the presence and the behavior of singular modes caused by specific boundary conditions in the fluid.
A NEW WAY TO EXTEND FUZZY IMPLICATIONS

The main purpose of this paper is to use a new way to extend fuzzy implications $I$ from a generalized sublattice $M$ to a bounded lattice $L$, such that the extended implications preserve many of the considered properties of fuzzy implications on $M$. Furthermore, as a special case, we investigate the extension of $(S,N)-$implications. Results indicate that the extended implications preserve many of the considered properties of $(S,N)$-implications.
Globalizing Corporate Governance: Convergence of Form or Function

This paper examines the interplay between selection-driven functional adaptivity on the one hand, and formal institutional persistence or path dependency on the other, that will determine whether such corporate governance convergence as we observe will be formal or functional. Five combinations of formal and functional covergence are considered: 1) purely functional convergence, as with the displacement of inefficient management; 2) the use of formal tools to catalyze the breakdown of formal barriers to functional convergence as with the elimination of tax on the sale of cross holdings; 3) the need for elements of both formal and functional convergence as with the creation of the institutional infrastructure that supports a venture capital market; 4) convergence by contract as with security design or foreign stock exchange listing; and 5) convergence through regulatory competition -- the hybrid of private and public ordering introduced to the European Community by the European Court of Justice's recent decision in Centros.
Hybrid Parallel Programming on HPC Platforms

Summary Most HPC systems are clusters of shared memory nodes. Parallel programming must combine the distributed memory parallelization on the node inter-connect with the shared memory parallelization inside of each node. Various hybrid MPI+OpenMP programming models are compared with pure MPI. Benchmark results of several platforms are presented. This paper analyzes the strength and weakness of several parallel programming models on clusters of SMP nodes. Benchmark results on a Myrinet cluster and on recent Cray, NEC, IBM, Hitachi, SUN and SGI platforms show, that the hybrid-masteronly programming model can be used more eciently on some vector-type systems, but also on clusters of dual-CPUs. On other systems, one CPU is not able to saturate the inter-node network and the commonly used masteronly programming model suers from insucient inter-node bandwidth. This paper analyses strategies to overcome typical drawbacks of this easily usable programming scheme on systems with weaker interconnects. Best performance can be achieved with overlapping communication and computation, but this scheme is lacking in ease of use.
User Needs for Mobility Improvement for people with Functional Limitations

According to the Eurostat statistics, 25.3% of the European Union (15 countries) population are “severely hampered” (9.3%) or “hampered to some extent” (16.0%). More specifically, these figures refer to “hampered in daily activities by any physical or mental health problem, illness or disability” (Simoes and Gomez, 2005; United Nations, 2003). Their quality of life would improve substantially if they could participate more actively in the society, while society itself could benefit from this contribution. The transdisciplinary project ASK-IT aims to support this and is developing an ambient intelligence system that provides information to people with functional limitations.
Everything is movement: on the nature of embodied communication

In this chapter we will introduce motion quality as an analog signal in communication. We will first give a short overview of the history of motion research, and then introduce a communication model that goes beyond signal ping-pong theories, based on the evolutionary constraints of communication. Last, empirical studies on motion quality show that motion quality can be assumed to be an honest signal about the sender’s physical and internal state, fit to be employed in communicative processes.
Feasibility of Strength-Balance Training Extended with Computer Game Dancing in Older People; Does it Affect Dual Task Costs of Walking?

Background: It is suggested that one of the reasons for the lack of effect in fall prevention programs is insufficient attention given to cognitive functions in the design of interventions. New treatments have to be piloted to test whether they are feasible and effective. The aim of this pilot study was to elucidate the feasibility and efficacy of an assisted living-based, twelve weeks combined physical-computer-game-training program for older people to inform a future Phase III trial. Secondary aim was elucidating the effects of the training program on brain associated spatial and temporal characteristics of gait. Materials and methods: We investigated the effects of a program with computer game dancing against usual care physical interventions in Swiss assisted living facilities. A controlled clinical trial experimental design was employed whereby participants in a facility were either allocated to 12 weeks usual care physical training (control group) or to 12 weeks physical training with integrated computer game dancing (experimental group). Main outcome measures were adherence rates, relative dual task costs of walking, and falls efficacy. Results: Adherence rate of the physical-computer-game-training was excellent with 96%. Results indicate a positive effect of the computer game dancing program on relative dual task costs of walking. The program significantly lowered the fear of falling. Conclusions: The findings from this pilot study suggests that a multicentre randomized clinical trial comparing usual care with physical-computer-game-training in older people in assisted living facilities is feasible. Pilot studies can improve the design of larger trials. A training programme with computer game dancing affects brain related walking functions, as opposed to usual care that showed no such effect.
Retrievability and Gradience in Filler-Gap Dependencies

The deﬁning characteristic, from a linguistic point of view, of certain kinds ofunbounded dependencies is that they violate one of a set of putatively univer-sal constraints on syntactic dependencies. These so-called ”island” constraintsobstruct or block ﬁller-gap dependencies into (or out of) particular syntactic con-ﬁgurations (Ross, 1967; Chomsky, 1973, 1977, 1986). Exempliﬁed below areviolations of two such constraints, known as the Wh-Island Constraint (1a) andSuperiority Condition (1b):(1) a. What don’t you remember who wrote? b. What did who read?

Wastewater use in India: the impact of irrigation weirs on water quality and farmer health

Water quality in the wastewater polluted Musi River, India was assessed in a 14 month survey, while the impact of exposure to polluted river water was assessed in an epidemiological study. The water quality survey found very high intestinal nematode and BOD concentrations in Musi water in the city of Hyderabad. Water quality improved dramatically downstream of the city as a result of irrigation weirs that were placed on the river and which promoted sedimentation. River water, at two of the selected sample points, was found to be unfit for use in agriculture based on WHO guidelines. Hookworm infection was found to be the main health risk associated with the use of polluted Musi water and a significantly increased risk of infection was found in farmers using untreated wastewater. In the absence of wastewater treatment facilities, regular anthelmintic treatment programs are recommended to protect farmer health.
