Exploring the etiological pathways of Problematic Pornography Use in NoFap/PornFree rebooting communities: A critical narrative analysis of Internet forum data
Objective: Problematic pornography use (PPU) has been extensively studied in terms of its negative implications for various life domains. The empirical literature reveals measured outcomes of interpersonal and intrapersonal dysfunction in participants’ everyday living, supporting its classification as a disorder. The increasing number of complaints around PPU opens the door to the creation of online self-help rebooting communities.
Method: This qualitative study aims to provide a better understanding of this behavior by investigating potential etiological pathways contributing to the onset of PPU, as they were expressed by members of the online NoFap/PornFree self-help communities with self-perceived PPU.
Results: The critical narrative analysis reveals a complex web of mutually informing causal connections. The dialectical relationship between situational resources, material conditions and an embodied spectator gives rise to an online persona with motivations of self-exploration, experimentation and socializing. A sense of vulnerability, also, renders the use of pornography as a means of escape and validation. Furthermore, commitment to abstinence, framed by the notions of recovery and relapse, is found to be a major factor for maintaining distress.
Conclusions: The study highlighted the need for a thorough understanding of the etiological pathways of PPU for a more effective and targeted intervention. Moving beyond biomedical conceptualizations suggests an intervention whereby PPU is placed in a context of a crisis of meaning
Poling of VDF/TrFe copolymers using a step-wise method
A new poling technique is presented, in which a series of five consecutive pulses of electric field, and with successively increasing strength is applied between the two electrodes of 65/35 VDF/TrFE copolymer based sensor. Between each pulse, the applied electric field is reduced to zero (short circuit). This allows deformations and space charges to be relax, resulting in more homogeneous electric field distribution with less risk for an electric breakdown. It is conducted at room temperature and is compatible with semiconductor technology. This step-wise poling technique is characterised by a low breakdown rate and yields a high pyroelectric coefficien
An integrated charge amplifier for a pyroelectric sensor
This paper presents an integrated charge amplifier that measures a small charge. This charge is generated by a pyroelectric detector. The charge amplifier consists of a single-stage c-annon source configuration with a passive feedback network. The charge amplifier has a bandwidth of 700 kHz and an output noise voltage of 20 nV Hz 1/2 at 1 kHz. A 2Ă—2 integrated pyroelectric sensor based on VDF/TrFE copolymer has been realized. The voltage response of this sensor-amplifier is reported
Managerial Unionism and the Law in New Zealand
This paper examines the issue of trade unionism amongst the fastest growing occupational group in New Zealand, which is also the least unionised, managers and administrators. Despite facing similar threats to employment security and changes to working conditions as other wage and salary earners, most managers and administrators do not have the benefits of a protective organisation to bargain on their behalf. The paper examines forms of collective representation for managers, but particularly incorporation and registration as a trade union. Problems associated with attempts to register managerial unions are discussed, and the particular case of APEX is examined. The paper concludes with some suggestions for changes to the law to ease the plight of those managers who wish to unionise, and summarises the current avenues available for collective representation
What is the impact of public care on children's welfare? A review of research findings from England and Wales and their policy implications.
The outcomes for children in public care are generally considered to be poor. This has contributed to a focus on reducing the number of children in care: a goal that is made explicit in the provisions of the current Children and Young Persons Bill. Yet while children in care do less well than most children on a range of measures, such comparisons do not disentangle the extent to which these difficulties pre-dated care and the specific impact of care on child welfare. This article explores the specific impact of care through a review of British research since 1991 that provides data on changes in child welfare over time for children in care. Only 12 studies were identified, indicating a lack of research in this important area. The studies consistently found that children entering care tended to have serious problems but that in general their welfare improved over time. This finding is consistent with the international literature. It has important policy implications. Most significantly it suggests that attempts to reduce the use of public care are misguided, and may place more children at risk of serious harm. Instead, it is argued that England and Wales should move toward a Scandinavian system of public care, in which care is seen as a form of family support and is provided for more rather than fewer children and families
Measurement of the ΔS=-ΔQ Amplitude from K_(e3)^0 Decay
We have measured the time distribution of the π^+e^-ν and π^-e^+ν modes from initial K^0's in a spark-chamber experiment performed at the Bevatron. From 1079 events between 0.2 and 7 K_S^0 lifetime, we find ReX=-0.069±0.036, ImX=+0.108_(-0.074)^(+0.092). This result is consistent with X=0 (relative probability = 0.25), but more than 4 standard deviations from the existing world average, +0.14 -0.13i
Bulk and surface energetics of lithium hydride crystal: benchmarks from quantum Monte Carlo and quantum chemistry
We show how accurate benchmark values of the surface formation energy of
crystalline lithium hydride can be computed by the complementary techniques of
quantum Monte Carlo (QMC) and wavefunction-based molecular quantum chemistry.
To demonstrate the high accuracy of the QMC techniques, we present a detailed
study of the energetics of the bulk LiH crystal, using both pseudopotential and
all-electron approaches. We show that the equilibrium lattice parameter agrees
with experiment to within 0.03 %, which is around the experimental uncertainty,
and the cohesive energy agrees to within around 10 meV per formula unit. QMC in
periodic slab geometry is used to compute the formation energy of the LiH (001)
surface, and we show that the value can be accurately converged with respect to
slab thickness and other technical parameters. The quantum chemistry
calculations build on the recently developed hierarchical scheme for computing
the correlation energy of a crystal to high precision. We show that the
hierarchical scheme allows the accurate calculation of the surface formation
energy, and we present results that are well converged with respect to basis
set and with respect to the level of correlation treatment. The QMC and
hierarchical results for the surface formation energy agree to within about 1

Treatment of interictal epileptiform discharges can improve behavior in children with behavioral problems and epilepsy
Objectives:
It is generally agreed that children should be treated for epilepsy only if they have clinical seizures. The aim of this study was to examine whether suppressing interictal discharges can affect behavior in children with epilepsy.//
Study design:
In a double-blinded, placebo-controlled, crossover study, 61 children with well-controlled or mild epilepsy were randomly assigned to add-on therapy with either lamotrigine followed by placebo or placebo followed by lamotrigine. Ambulatory electroencephalographic recordings and behavioral scales were performed during baseline and at the end of placebo and drug phases. The primary hypothesis to be tested was that behavioral scales would improve specifically in patients with a reduction of electroencephalographic discharges during active drug treatment.//
Results:
Global rating of behavior significantly improved only in patients who showed a significant reduction in either frequency (P < .05) or duration of discharges (P < .05) during active treatment but not in patients with without a significant change in discharge rate. This improvement was mainly seen in patients with partial epilepsy (P < .005).//
Conclusions:
Our data suggest that suppressing interictal discharges can improve behavior in children with epilepsy and behavioral problems, particularly partial epilepsy. Focal discharges may be involved in the underlying mechanisms of behavioral problems in epilepsy
Dairy Cow Performance Associated with Two Contrasting Silage Feeding Systems
As a result of increasing labour costs, the lack of skilled labour, and the desire of many farmers to reduce their working hours, there is considerable interest in using simple feeding systems for dairy cows. A study was conducted to compare two silage feeding systems that differed in complexity
