Sexual Harassment is an unwelcome behaviour of sexual nature. Harassment can include “sexual harassment” or unwelcome sexual advances, requests for sexual favours, and other verbal or physical harassment of a sexual nature. It can be physical, verbal and written that tends to create a hostile or offensive work environment.

The Supreme Court of India defined Sexual Harassment as any unwelcome sexually determined behaviour (whether directly or by implication) such as

  1. Physical contact and advances,
  2. A demand or request for sexual favours,
  3. Sexually coloured remarks,
  4. Showing pornography,
  5. Any other unwelcome physical, verbal or non-verbal conduct of sexual nature.

Sexual Harassment of Women at Workplace as a Problem:

Sexual Harassment is one of the biggest problems our women are facing today in different sectors of life. Sexual Harassment at work is an extension of violence in everyday life and is discriminatory, exploitative, thriving in the atmosphere of threat, terror and reprisal. The victims fear to report the same to the higher officials or the concerned authorities. They fear to file a complaint against such offenders who does such heinous acts. The fear is due to the fear of boss, fear of guilt in the society that they might have to face, fear of being thrown out of the job or being demoted, fear that it will jeopardize their career as in it will put a blot on their resume and would render them un-hireable.

Sexual harassment includes many things:

  1. Actual or attempted rape or sexual assault.
  2. Unwanted deliberate touching, leaning over, cornering, or pinching.
  3. Unwanted sexual teasing, jokes, remarks, or questions.
  4. Whistling at someone.
  5. Kissing sounds, howling, and smacking lips.
  6. Touching an employee's clothing, hair, or body
  7. Touching or rubbing oneself sexually around another person.

Procedure to lodge/file a complaint:

Complaints regarding Sexual Harassment against women can be made either in paper form or by sending e-mail to icc[dot]ncess[at]gmail[dot]com.

The Act stipulates that aggrieved woman can make written complaint of sexual harassment at workplace to the ICC or to the LCC (in case a complaint is against the employer), within a period of three months from the date of the incident and in case of a series of incidents, within a period of three months from the date of last incident.

As per the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Rules, 2013, in case the aggrieved woman is unable to make a complaint on account of her physical incapacity, a complaint may be filed inter alia by her relative or friend or her co-worker or an officer of the National Commission for Woman or State Women's Commission or any person who has knowledge of the incident, with the written consent of the aggrieved woman.

Ministry of Women & Child Development launched an online complaint management system titled Sexual Harassment Electronic-Box (SHe-Box) on 24th July, 2017 for registering complaints related to Sexual Harassment at the workplace. The SHe-Box is an initiative to provide a platform to the women working or visiting any office of Central Government (Central Ministries, Departments, Public Sector Undertakings, Autonomous Bodies and Institutions etc.) to file complaints related to Sexual Harassment at the workplace under the Sexual Harassment of Women at workplace (Prevention, Prohibition and Redressal) Act, 2013.

Once a complaint is submitted to She-Box, it will be directly sent to the Internal Complaint Committee (ICC) of the concerned Ministry/ Department/ PSU/ Autonomous Body, etc. having jurisdiction to inquire into the complaint. The SHe-Box also provides an opportunity for both the complainant and nodal administrative authority to monitor the progress of inquiry conducted by the ICCs. The complainant can ask for a transfer (for herself or the respondent) / 3 months leave or other relief during inquiry period. The inquiry should be completed within a period of 90 days from the day of complaint. Non-compliance is punishable.

Debunking The Myths and Misconception about Sexual Harassment

  1. Myth: Only women are harassed and only men are sexual harassers.
    Fact: Anyone, irrespective of gender can be the victim of harassment or a harasser.
  2. Myth: People invite sexual harassment through their behaviour or dress.
    Fact: Sexual harassment is not a motivated act, but an expression of hostility and/or power focused on differences in gender or sexual orientation. People do not invite sexual harassment.
  3. Myth: If ignored, the problem of sexual harassment and stalking will go away.
    Fact: Generally, the harasser is persistent and does not stop on his/her own. The harasser often has more targets. If ignored by the harassed, the harasser may interpret such behaviour as consent or motivation.
  4. Myth: Sexual Harassment is a rare occurrence.
    Fact: The rate of sexual harassment is increasing throughout the world day by day. It is not a rare occurrence at all. Such incidents keep taking place every day. Few victims take strict against the harasser while a few incidents go unnoticed or are not complained about.

False Complaints and Consequences

According to the Act, if a complaint is made with malicious intent which is substantiated then it shall attract repercussions under Section 14 or if there is any false complaint backed with forged document then strict action will be taken according to the service rules. If it is found that a person has filed a false complaint, then the ICC will award the same punishment to the person who has filed the wrong complaint as per Rule 10 of the Rules.

Isotope Geochemistry Facility

 

NCESS has established an advanced analytical facility for isotope geochemistry and geochronology studies. The facility incorporates ICP-MS and MC-ICPMS which can be integrated with a Laser Ablation Microprobe (LAM). This combination of instruments can provide major and trace element abundances, isotopic characterisation, in-situ U-Pb dating and measurement of precise hafnium isotope ratios of various accessory mineral phases in rocks.

Instrumentation

Teledyne CETAC LSX-213 G2+ laser ablation system: The Teledyne CETAC LSX-213 G2+ laser ablation system offering a 5ns shot pulse is capable of generating > 3 mJ/pulse of laser energy with a spot size range between 4-200 μm. This allows improved absorption of energy and less transmission of the beam into the underlying epoxy. This aids in retarding the instability and U-Pb fractionation during spot analysis which indeed reduces the stabilization period allowing a short warm-up time. The laser is characterized by a flat-topped beam energy profile with pulse width < 5 nsec, enabling a repetition rate up to 20 Hz. The system is equipped with a HeLEx II sample ablation cell allowing automated stage translation with a precision of ±2–3 μm for pre-setting of analytical points. The HeLEx II with an internal volume cup enables effective sample transportation to the ICPMS through the articulated gas inlet/outlet arm. The ablated material from the sample is pushed out of the chamber by purging helium gas which later mixes with the carrier argon gas and gets transported into the plasma. The fast washout of the laser ablation system allows rapid measurement of elements with a minimal fractionation effect.

Agilent 7800 Quadruple ICPMS: The Agilent 7800 Quadrupole ICPMS is equipped with a dual-mode discrete dynode electron multiplier as an ion detector. The quadrupole mass analyzer is a 3 MHz hyperbolic rod having a mass range 2–260 u and variable mass resolution from 0.3 u to 1.0 u. This enables a sensitivity ≤ 5 × 10-7 counts for low masses and ≤ 1 × 10-7 counts for higher masses. The Scott-type double-pass quartz spray chamber with High Matrix Introduction system tandem with 500 - 1600W RF generating capability allows complete ionization of the introduced sample. The Octopole Reaction System (ORS) with He gas in the cell interacts with the ions from the sampling cone to avoid the interference of polyatomic molecules.

Nu Plasma III Multi collector ICPMS: Nu-PLASMA-III is a double-focusing Multi Collector ICP Mass Spectrometer (MC-ICP-MS) designed to provide a high precision isotope ratio of elements. The MC-ICPMS is equipped with 16 Faraday detectors, 2 Daly detectors and 4 Ion counters. The instrument retains the unique, patented, variable dispersion Zoom lens enabling the simultaneous measurement of the isotopes of elements from lithium to the actinide series on its static collector arrays. This allows comprehensive coverage of different isotopic applications over the full mass range.

Calibration strategy

U-Pb geochronology using LA-ICPMS: The ICPMS is tuned for U-Pb geochronology by ablating a raster over NIST 610 (Pearce et al., 1997) standard glass reference material to get the maximum signal intensity and stability for analyzed masses. The ICPMS parameters along with nebulizer and laser gas flows are adjusted to achieve maximum counts for the monitored masses keeping U/Th ratio ~1. Plasma oxidation level is monitored by Th/ThO ratio and double charged ion ratio was monitored using Ca/Ca2+. The He flow is optimized to get maximum counts and to minimize fractionation during sample transport. Spot analysis on accessories is conducted at a spot size of 30 microns with a laser fluence of ~4 J/cm2 on the sampling surface and a repetition rate of 10 Hz in Q-switch mode. LIEF correction is applied using zero ablation time intercepts of least-squares linear regression lines fitted to the time-resolved isotopic ratio data using the protocol of Košler and Sylvester (2003) whereas inter-element fraction and instrumental mass discrimination are corrected by normalization to a matrix-matched primary reference material, which is analyzed during the analytical sessions under the same conditions as the samples. In-situ trace element determination is carried out using NIST 612 and NIST 610 (Pearce et al., 1997) as reference standards for time-drift correction and quality monitoring. Off-line data reduction is carried out using Iolite 4.1, ICPMS DataCalc 12.0 and Glitter software.

Lu-Hf measurements in zircons using LA-MC-ICPMS: Zircons analyzed for U-Pb dating will be reanalyzed and the laser spots positioned as close as possible to the previous crater. Before integrating with the LA, pure 25 ppb JMC 475 solution is analyzed for calibration and peak selection. For hafnium measurement, the laser is operated at a spot size of 50 μm at 10 Hz repetition rate in Q-switch mode, imparting a laser fluence of ~3 J/cm2 in the sample surface. Data are reduced off-line and calculated isotopic ratios and elemental concentrations are processed using Iolite 4.1. Isotopic fractionation of Hf is determined by measuring interference-free 179Hf/177Hf and βHf is determined using a constant 179Hf/177Hf value of 0.7325 (Patchett et al.,1981). Similarly, isotopic fractionation of Yb is corrected by calculating βYb using the measurement of interference-free 173Yb/171Yb using a constant 173Yb/171Yb value of 1.132685 (Vervoort et al., 2004). Correction for the interference of 176Yb on 176Hf is carried out by measuring the interference-free 173Yb and using the constant 176Yb/173Yb value of 0.796218 (Chu et al., 2002).

Detailed analytical protocol for all these techniques is according to “Dev, J. A., Tomson, J. K., Sorcar, N., & Nandakumar, V. (2021). Combined U-Pb/Hf isotopic studies and phase equilibrium modelling of HT-UHT metapelites from Kambam Ultrahigh temperature Belt, South India: Constraints on tectonothermal history of the terrain. Lithos, 106531 (DOI; https://doi.org/10.1016/j.lithos.2021.106531) .”

Sample Preparation

Accessory minerals are analyzed in both mineral separates as well as in thin sections. Accessory minerals are separated from bulk rock samples using conventional Wilfley table and magnetic separation methods in the Thin section and Sample preparation Laboratory at NCESS. The handpicked grains are mounted in epoxy-filled blocks of 2.5 cm diameter and subsequently sectioned and polished. Grain mounts are later cleaned in different steps with ethanol and deionized water in an ultrasonic bath to remove surface contamination during sample preparation before insertion into the laser sample cell. This allows skipping pre-ablation during LA analysis even though pre-ablation is carried out in rare cases if surface contamination is noticed. The internal structure of targeted minerals is studied using backscattered electron (BSE) and cathodoluminescence (CL) images taken either from SEM or EPMA laboratories at NCESS.
