Psychological ownership in organization: A contribution to the Italian validation of pierce and colleagues scale

We present a contribution to the Italian validation of the scale of Pierce Van Dyne e Cummings (1992) concerning the organizational ownership. This construct even internationally widely adopted is mostly absent in the scientific Italian debate. Using data from a sample of 598 Italian employees, was studied both the internal and external validity of the version with seven items that of the one with four. The results showed better psychometric properties of the shorter version and good evidence with regard to internal and external validity

A diagnostic tool to evaluate the proactivity levels of risk-Reporting activities by the workforce

Prevention of occupational injuries is an important task of Human Resource Management. Empiric research showed that risk perception, safety communication and worker's participation in safety programs may have a relevant role in reducing accident and injury occurrence - see for example (Conchie, 2013). These considerations lead us to this study to propose a new methodology which consists in an index aimed to assess the proactivity of worker participation in safety management systems. The innovation consists in defining a diagnostic measurement model to assess the degree of workforce proactivity, considering a specific kind of participatory contribute by workers for safety promotion in the workplace, like the spontaneous risk-reporting initiatives. The measurement tool has been defined and tested by an interdisciplinary team composed of four university researchers (human factor experts) and two site safety managers of a chemical site which is chosen with the purpose to apply for the first time the new tool. Preliminary results show that different levels of proactivity were adopted and that the highest levels of proactivity are relatively less frequent. The tool offers relevant diagnostic information for the industrial organizations which aim to achieve higher level of proactivity in risk management, offering practical indications for managerial interventions focused on stimulating and improving appropriate participation by the workforce. © Copyright 2014, AIDIC Servizi S.r.l

Online recruitment: The role of trust in technology

In recent years, online recruitment has become a prevalent human resource management practice worldwide. Although studies emphasized the importance of candidates' perceptions related to the recruiting web site attributes, there is no research focused on the effects of trust toward the IT technology during the online application process. Given the importance of trust dynamics in personnel recruitment, the aim of this study is to investigate the role of trust towards the web platforms supporting online recruitment. Results, from a sample of university students including 330 participants, showed that trust toward the web site affects both directly and indirectly - via company attractiveness - the intention to apply for a job

Testicular histopathology, semen analysis and FSH, predictive value of sperm retrieval: supportive counseling in case of reoperation after testicular sperm extraction (TESE)

Background: To provide indicators for the likelihood of sperm retrieval in patients undergoing testicular sperm extraction is a major issue in the management of male infertility by TESE. The aim of our study was to determine the impact of different parameters, including testicular histopathology, on sperm retrieval in case of reoperation in patients undergoing testicular sperm extraction. Methods: We retrospectively analyzed 486 patients who underwent sperm extraction for intracytoplasmic sperm injection and testicular biopsy. Histology was classified into: normal spermatogenesis; hypospermatogenesis (reduction in the number of normal spermatogenetic cells); maturation arrest (absence of the later stages of spermatogenesis); and Sertoli cell only (absence of germ cells). Semen analysis and serum FSH, LH and testosterone were measured. Results: Four hundred thirty patients had non obstructive azoospermia, 53 severe oligozoospermia and 3 necrozoospermia. There were 307 (63%) successful sperm retrieval. Higher testicular volume, lower levels of FSH, and better histological features were predictive for sperm retrieval. The same parameters and younger age were predictive factors for shorter time for sperm recovery. After multivariable analysis, younger age, better semen parameters, better histological features and lower values of FSH remained predictive for shorter time for sperm retrieval while better semen and histology remained predictive factors for successful sperm retrieval. The predictive capacity of a score obtained by summing the points assigned for selected predictors (1 point for Sertoli cell only, 0.33 points for azoospermia, 0.004 points for each FSH mIU/ml) gave an area under the ROC curve of 0.843. Conclusions: This model can help the practitioner with counseling infertile men by reliably predicting the chance of obtaining spermatozoa with testicular sperm extraction when a repeat attempt is planne

The role of prosocial and proactive safety behaviors in predicting safety performance

© 2015 Elsevier Ltd. Employees' engagement in safety is assumed to be a significant contributor to safety performance within the chemical industry. The current study tested this assumption by examining the role of prosocial safety behaviors (e.g., helping others) and proactive safety behaviors (e.g., seeking change) in predicting four safety performance outcomes: micro-accidents, property damage (accidents without injury), near-miss events, and lost-time injuries. Two-wave data collected from 511 employees located in 2 Italian chemical plants revealed that prosocial safety behaviors predicted micro-accidents and property damage, and proactive safety behaviors predicted near-miss events and lost-time injuries. These results suggest that benefits can be gained from distinguishing between prosocial and proactive safety behaviors when seeking to improve safety performance. Organizations may reduce the rate of minor injuries and property damage by increasing helping among employees. However, this approach will be less effective in reducing more serious accidents or increasing near-miss event reporting. More effective in these cases is creating environments in which employees feel able to raise their suggestions and concerns about safety

Proactivity-and-consequence-based safety incentive (PCBSI) developed with a fuzzy approach to reduce occupational accidents

© 2015 Elsevier Ltd. This study introduces a new reward system for enhancing safety during work activities, by improving workers' motivation in performance and thereby reducing occupational accidents. The reward system is based on a safety incentive that can be defined by means of two parameters: the worker behavior, which is measured especially in terms of proactivity (namely workers' attitude in reporting potentially hazardous situations) and the consequences that could be avoided thanks to the reporting activity. In doing this, the fuzzy logic theory can be usefully applied, because it offers the opportunity to quantify the two parameters taking into account their vagueness, through the concept of degree of membership and then it also allows to combine them into the final value of the safety incentive through a Fuzzy Inference System (FIS). The model, named "Proactivity-and-Consequence Based Safety Incentive" (PCBSI), has been tested in an Italian chemical plant, with the purpose to evaluate its effectiveness

PRNP P39L variant is a rare cause of frontotemporal dementia in Iialian population

The missense P39L variant in the prion protein gene (PRNP) has recently been associated with frontotemporal dementia (FTD). Here, we analyzed the presence of the P39L variant in 761 patients with FTD and 719 controls and found a single carrier among patients. The patient was a 67-year-old male, with a positive family history for dementia, who developed apathy, short term memory deficit, and postural instability at 66. Clinical and instrumental workup excluded prion disease. At MRI, bilateral frontal lobe atrophy was present. A diagnosis of FTD was made, with a mainly apathetic phenotype. The PRNP P39L mutation may be an extremely rare cause of FTD (0.13%)

Fibroma of tendon sheath located within the ankle joint capsule

We report a very rare case of fibroma of the tendon sheath arising from the anteromedial ankle joint capsule, with no apparent connection to any tendon in the area, found in a 58-year-old patient complaining of progressive local swelling. This uncommon tumor has its usual localization in tendon sheaths, is extremely rare in joint capsules, and has never been described in this location previously. MRI showed nonuniform low signal intensity in T1- and T2-weighted images and high intensity in STIR images. The mass was completely excised by open surgery. Histopathological analysis later confirmed the diagnosis of a fibroma of the tendon sheath

Characterization of the Earwig, Doru lineare, as a Predator of Larvae of the Fall Armyworm, Spodoptera frugiperda: A Functional Response Study

Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) is considered as the most important pest of maize in almost all tropical America. In Argentina, the earwig Doru lineare Eschscholtz (Dermaptera: Forficulidae) has been observed preying on S. frugiperda egg masses in corn crops, but no data about its potential role as a biocontrol agent of this pest have been provided. The predation efficiency of D. lineare on newly emerged S. frugiperda larva was evaluated through a laboratory functional response study. D. lineare showed type II functional response to S. frugiperda larval density, and disc equation estimations of searching efficiency and handling time were (a) = 0.374 and (t) = 182.9 s, respectively. Earwig satiation occurred at 39.4 S. frugiperda larvae
